Barograph uses the new iPhone pressure sensor

The new iPhone 6 and 6 Plus each have a pressure sensor that gives readings for barometric pressure. Barograph (free), displays real-time pressure data from that sensor. Weather watchers will know dropping pressure usually means bad weather is coming, rising pressure means good weather.

The app's main interface is a graph that looks for very small changes. Initially it might seem uneven, but you can usually spot a trend pretty easily. The app charts the pressure and your relative altitude.

If you leave the app or lock your phone, the readings stop after 30 seconds so the app is not a battery drain. Pressure readings are in kiloPascals, not a measurement consumers typically use when reading barometers, but what you are looking for is trends. It would be nice if the app gave you the ability to see the data in U.S. non-metric readings.

You can share your barometric readings via Facebook, Twitter and email, if that suits your fancy. You can also save the graph to your image library.

Developer Jackson Myers told me the app is a first try, and it will get more sophisticated, but it does provide an interesting look into some of the new data the iPhone sensors are offering.

The app of course requires iOS 8 or greater, and must run on an iPhone 6 or 6 Plus.

MIT researchers develop wearable toxic gas sensor

A team of four MIT researchers has developed a new wearable sensor that can detect toxic gases and talk to smartphones or other wireless devices to warn users when they are in danger.

Using these gas sensors, the researchers hope to design badges that weigh less than a credit card and can be easily worn by military personnel on the battlefield.
“Soldiers carry a lot of equipment already, and a lot of communication devices,” said Timothy Swager, Professor of Chemistry at MIT and lead author on a paper describing the sensors that was published in the Journal of the American Chemical Society. The paper’s co-authors are post-doc student Shinsuke Ishihara and PhD students Joseph Azzarelli and Markrete Krikorian.
“Soldiers have no wearable sensors to detect toxic gases. They use a variety of detectors, but they’re not the kind of thing you can carry around. Our sensors weigh less than a piece of paper,” Swager said.
In layman’s terms, the system works as follows. The sensor is a circuit loaded with carbon nanotubes. Carbon nanotubes are cylindrical molecules that look like little wires.
“Let’s think about the wires we’re familiar with, such as electric wires,” Swager explained. “They’re wrapped in plastic.” As a result, the actual wire is insulated from the external environment and users are safe. In the carbon nanotubes case, insulation is not achieved thanks to a plastic case. “We wrapped the nanotubes with a polymer,” Swager explained.
When exposed to toxic gases, such as Sarin gas, the polymer breaks apart and the insulation disappears. Consequently, the nanotubes touch each other and become conductive. When this happens, a signal is sent to the smartphone.
To detect the signal, the smartphone or the wireless device must be equipped with near-field communication (NFC) technology, which allows the devices to transmit data over short distances without the need for internet connection.
The sensor’s response is irreversible, meaning that users can see they’ve been exposed to a certain amount of toxic gas even though the gas is not detected anymore in the air.
“There are sensors that give reversible response, so things go up and if you take away the signal they go back again. But this one is different: The response is irreversible, so you can get the total dosage,” Swager said.
The toxic-gas detector — composed of the wearable badge and the communication device — may also have civilian applications in refineries, where workers might be exposed to toxic chemicals.
According to Swager, the technology to develop the product has already been licensed by C2Sense, a company based in Cambridge, Mass. Swager said the company is working on commercializing the product: “I think it would be at least a year.”

Automatic rearview mirror system using a photosensor array

A system apparatus, structure and method for controlling a plurality of variable reflectance mirrors (or mirror segments), including a rearview mirror and side view mirrors, which change their reflectance level in response to a plurality of drive voltages applied thereto, for an automotive vehicle. The system includes a light sensing device and a control circuit formed as a single VLSI CMOS circuit. The light sensing device comprises a photosensor array having a field of view encompassing a rear window area and at least a portion of at least one side window area of the vehicle. The logic and control circuit determines a background light signal from photosensor element signals generated by the photosensor elements in the photosensor array indicative of light levels incident on the photosensor elements. The circuit also determines a peak light signal in three different zones or sub-arrays of the photosensor array. The zones or sub-arrays may correspond to three mirrors or mirror segments. The peak light signals in each of the zones and a common background light signal are used to determine independent and separate control signals, which are then output to separate mirror drive circuits for independently controlling the reflectance level of the rearview mirror and the left and right side view mirrors, or alternatively the segments of a mirror.
Description
This application is a divisional of application Ser. No. 08/023,918 filed Feb. 26, 1993, now U.S. Pat. No. 5,550,677.
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an automatic rearview mirror system for automotive vehicles which automatically changes reflectance level in response to glare causing light, and more particularly relates to an improved automatic rearview mirror system using only a rearwardly facing sensor.
2. Description of Related Art
Automatic rearview mirrors and mirror systems have been devised for varying the reflectance level of a variable reflectance rearview mirror by reducing the reflectance automatically in response to annoying glare light, as seen rearwardly of the rearview mirror or mirrors by a driver of the vehicle, and by increasing automatically the reflectance to a normal or maximum reflectance level when the annoying glare light subsides. These automatic mirrors have been changed over the years in an effort to improve their performance characteristics and associated level of glare protection.
Early automatic rearview mirrors used a rearwardly facing sensor and control circuit to change mirror reflectance. One example of such a "single-sensor" type mirror is described in U.S. Pat. No. 4,266,856. In these prior art single-sensor type mirrors, the rear glare light was incident on a rearwardly facing sensor or photocell, such as a photodiode, photoresistor or phototransistor. These mirrors suffered from various problems, however, including the problem that these mirrors would become increasingly sensitive and even "lock-up" in their minimum reflectance level or state as the driver encountered significantly higher light levels in town or city driving. This required the driver to repeatedly adjust the mirror's sensitivity control to prevent such problems.
To overcome the problems of single-sensor type mirrors, a non-rearwardly facing photocell for sensing "ambient" light was added. It was believed that the desired reflectance necessary to relieve the driver from glare depended not only on glare light but also on ambient light. Accordingly, these "two-sensor" type mirrors used two separate photocells, one generally facing rearwardly and one generally facing forwardly (or other non-rearwardly facing direction) of the mirror or vehicle. The signals from these two photocells were then compared in some fashion, and when, for example, the glare light from the rear was comparatively high with respect to the "ambient" light, a control circuit would apply a control signal to reduce mirror reflectance. Some examples are described in German Laid-Open Patent No. 3,041,692; Japanese Laid-Open Patent No. 58-19941; and U.S. Pat. Nos. 3,601,614; 3,612,666; 3,680,951; 3,746,430; 4,443,057; 4,580,875; 4,690,508; and 4,917,477. In many of these prior art automatic rearview mirrors, light generally forward of the mirror or vehicle was incident on the second photocell.
These arrangements, however, also had problems. In some of these mirrors the forwardly facing or "ambient" light sensor was inaccurate because it did not correctly measure ambient light levels since it did not include light generally rearward of the mirror or vehicle. Some examples include the devices described in U.S. Pat. Nos. 4,443,057 and 4,917,477. Other prior art devices overcame these deficiencies by providing a control circuit which correctly measured ambient light as a combination of both the forward and rear light levels. Examples of this significantly different approach are described in U.S. Pat. Nos. 4,793,690 and 4,886,960.
The prior art two-sensor type systems generally provided improved performance over prior art single-sensor type systems but were also more complex and costly. In part, this was because using separate forwardly and rearwardly facing photocells required that the performance characteristics of the two separate photocells, such as photoresistors, be matched appropriately to ensure consistent performance under various operating conditions. Matching photocells such as photoresistors, however, generally involves complex, expensive and time consuming operations and procedures.
Both the prior art single-sensor and two-sensor type mirrors presented additional problems when they were also used to control the exterior side view mirrors. This is because such prior art systems used a common control or drive signal to change the reflectance level of both the interior rearview mirror and the exterior left and/or right side view mirrors by substantially the same amount. In U.S. Pat. No. 4,669,826, for example, a single-sensor type mirror system used two rearwardly facing photodiodes to control both an interior rearview mirror and the left and/or right side view mirrors based on the direction of incident light from the rear. Another example includes the two-sensor type system described in U.S. Pat. No. 4,917,477.
In rearview mirror systems, however, each of the interior rearview and exterior side view mirrors may reflect different source light levels. More specifically, the inside rearview mirror, left side view mirror and right side view mirror each enable the driver to view a different portion or zone of the total rearward area. Of course, there may be some overlap of the image information contained in each of the three zones. The situation is further complicated with multi-lane traffic because each of the mirrors reflects different light levels caused by the headlights of the vehicles which are following, passing or being passed. As a result, in the prior art systems, when the reflectance level of the interior rearview mirror was reduced to decrease the glare of headlights reflected therein, the reflectance level of the exterior left and right side view mirrors was also reduced by substantially the same amount, even though, for example, the side view mirrors might not be reflecting the same level of glare light, if any. Accordingly, rear vision in the exterior left and right side view mirrors could be improperly reduced.
Other prior art two-sensor type systems used a common ambient light sensor and several rearwardly facing sensors, one for each of the mirrors. An example is the alternate system also described in U.S. Pat. No. 4,917,477. This approach is not satisfactory, however, because it reduces system reliability and increases complexity and cost.
Finally, some prior anti-glare mirrors used several sensors to control the segments of a variable reflectance mirror. One example is disclosed in U.S. Pat. No. 4,632,509, which discloses a single-sensor type mirror using three rearwardly facing photocells to control three mirror segments depending on the direction of incident light from the rear. See also U.S. Pat. No. 4,697,883. These prior mirror systems generally have the same problems as the other single-sensor type mirrors. Some other anti-glare mirrors are generally disclosed in U.S. Pat. Nos. 3,986,022; 4,614,415; and 4,672,457.
Consequently, there is a need for an automatic rearview mirror system for an automotive vehicle having improved reliability and low cost, which accurately determines or otherwise discriminates light levels that the driver will experience as glare without the need for a separate forwardly facing photocell. In addition, as noted above, there is also a need for an automatic rearview mirror system of high reliability and low cost, which accurately determines light levels that the driver will experience as glare, and which can control independently the reflectance of a plurality of mirrors according to the light levels actually reflected by each of the rearview and exterior side view mirrors without the need for additional and separate rearwardly facing photocells. There is also a need for an automatic rearview mirror system that can independently control the segments of a variable reflectance mirror while accurately determining light levels that the driver will experience as glare in each segment of the mirror without the need for additional and separate forwardly and rearwardly facing photocells.

MIT Researchers Create Wearable Toxic Gas Sensor Lighter Than Paper

Massachusetts Institute of Technology wearable toxic gas sensor was created by four researchers. The device functions by detecting toxic gases and warn users by talking to the smartphones or other wireless devices when danger is near.

Researchers, who have developed wearable toxic gas sensors, also hope to create badges that weigh less than an average credit card so the military can wear them easily in battlefields.

MIT toxic gas sensor updates a smartphone or other wireless devices when a conduction of the nanotubes occurs. It can help people who are exposed to toxic gases like a Sarin gas. The polymer breaks causing the insulation to disappear and makes the nanotubes touch one another forming a conduction. When there's a conduction, the signal is directly sent to a smartphone or other wireless devices.

To detect the signal, the phone or device should be equipped with a near field communication (NFC) technology. The NFC allows devices to transmit data over short distances without using internet connection. The wearable toxic gas sensor has an irreversible response. This means that the wearers can see when they've been exposed to amounts of toxic gas even if it's undetected in the air.

MIT toxic gas sensor leading author and Chemistry professor Timothy Swager described the technology in the journal of American Chemical Society. The co-authors of the study are postdoctoral candidate Shinsuke Ishihara and PhD students Markrete Krikorian and Joseph Azzarelli.  

Swager said that soldiers already carry a lot of equipment and communication devices and at present, wearable toxic gas sensors are not used by soldiers. Swager also said that soldiers have many detectors, but they are not the type that can be carried easily, especially in the battlefield.

The wearable toxic gas sensor is said to weigh less than a piece of paper. The sensor is built out of a circuit filled with carbon nanotubes. These tubes are cylindrical and looks similar to little wires.

Wearable gas sensors are likened to electrical wires because they are wrapped in plastic to secure them from harsh effects of the external environment. However, the nanotubes used on the wearable gas sensors are wrapped with a polymer material rather than plastic because the latter would be unable to insulate the nanotubes.

Miniature pressure sensors for medical touch

A new kind of flexible, transparent pressure sensor, developed at the University of California, Davis, for use in medical applications, relies on a drop of liquid.

The droplet goes in a flexible sandwich of the substance polydimethylsiloxane, or PDMS. The sensor acts as a variable electrical capacitor. When the sensor is pressed down, the sensing droplet is squeezed over conductive electrodes, increasing its capacitance.

"There's a huge need for flexible sensors in biosensing," said Professor Tingrui Pan, who led the research project.

He and his colleagues used the sensor successfully in measuring the pulse in the human neck. The sensor also could be used in "smart gloves," giving physicians an enhanced ability to measure the firmness of tissues and detect tumors, and in "smart contact lenses," to monitor intraocular pressure without affecting vision.

Pan's research paper — for which graduate students Baoqing Nie and Siyuan Xing and ophthalmology professor James Brandt served as co-authors — appeared in the December issue of the journal Lab on a Chip.

Gas sensors 'see' through soil to analyze microbial interactions

Rice University researchers have developed gas biosensors to "see" into soil and allow them to follow the behavior of the microbial communities within.
In a study in the American Chemical Society's journal Environmental Science and Technology, the Rice team described using genetically engineered bacteria that release methyl halide gases to monitor microbial gene expression in soil samples in the lab.
The bacteria are programmed using synthetic biology to release gas to report when they exchange DNA through horizontal gene transfer, the process by which organisms share genetic traits without a parent-to-child relationship. The biosensors allow researchers to monitor such processes in real time without having to actually see into or disturb a lab soil sample.
The Rice researchers expect their technique will serve the same purpose for environmental scientists that fluorescent reporter proteins serve for biochemists who track protein expression and other processes in biological systems.
The work by the Rice labs of biogeochemist Caroline Masiello, biochemist Jonathan Silberg, microbiologist George Bennett and lead author Hsiao-Ying (Shelly) Cheng, a Rice graduate student, is the first product of a $1 million grant by the W.M. Keck Foundation to develop gas-releasing microbial sensors.
"This paper describes a new tool to study how microbes trade genetic material in the environment," said Masiello, a professor of Earth science.
"We care about this because the process of horizontal gene transfer controls a lot of things that are important to humans either because they're good—it's how rhizobia trade the genes they need to fix nitrogen and support plant growth—or they're bad—it's how bacteria trade antibiotic resistance in soils," she said. "It's been much more challenging in the past to construct models of this dynamic process in real soils and to study how horizontal gene exchange varies across soil types. We've created a new set of tools that makes that possible."
The researchers expect scientists will use gas biosensors in the lab to study nitrogen fixing in agriculture, antibiotic exchange in wastewater treatment, gene transfer in conditions where nutrients are scarce and the relationship between gene expression in soil and the release of greenhouse gases.
"There are other technologies that will build on this," said Silberg, an associate professor of biochemistry and cell biology. "The idea of using gases opens up most anything that's genetically encoded. However, we do need to improve technologies for some of the subtler kinds of questions."
He said releasing and sensing methyl halide gas represented an easy proof of concept. "Now we want higher-resolution information about other types of biological events by creating more sophisticated genetic programs using synthetic biology," Silberg said.
They expect they will soon be able to test agricultural soil samples to help fine-tune crop growth through more efficient watering and fertilizer use. "How can agriculture get this extra level of efficiency without the waste? Lots of people are coming to that, and there are lots of ways to do it," he said. "We're trying to build high-tech tools that allow us to understand mechanisms to make reliable predictions. That's the long game with these tools."
The researchers emphasized that these are tools for soil studies within lab environments. The synthetic microbes are destroyed once the results are obtained.
The Rice lab tested soil samples from the National Science Foundation's Kellogg Biological Station Long-Term Ecological Research Site in Michigan after adding Escherichia coli bacteria programmed to release gas upon transfer of their DNA to another microbe. Signals from the gas were up to 10,000 times the lab's detection limit.
The gas sensors were effective in anoxic—or oxygen-depleted—conditions, unlike green fluorescent protein, which requires oxygen to work. It is anticipated the reporter proteins can be used in many kinds of soil microbes, and some are currently being tested, Bennett said.

Patterning, integration and characterisation of polymer optical oxygen sensors

This paper describes a process for the layer-by-layer fabrication and integration of luminescent dye-based optical oxygen sensors into microfluidic devices. Application of oxygen-sensitive platinum(ii) octaethylporphyrin ketone fluorescent dye dissolved in polystyrene onto glass substrates by spin-coating was studied.

Soft lithography with polydimethylsiloxane (PDMS) stamps and reactive ion etching in oxygen plasma were used to produce sensor patterns with a minimum feature size of 25 microm. Sensors patterns were integrated into a PDMS microfluidic device by plasma bonding. No degradation of the sensor response as a result of the lithography and pattern-transfer processes was detected. Gaseous and dissolved oxygen (DO) detection was characterised using fluorescence microscopy. The intensity signal ratio of the sensor films was found to increase almost two-fold from 3.6 to 6.8 by reducing film thickness from 1.3 microm to 0.6 microm.

Calibration of DO measurement showed linear Stern-Volmer behaviour that was constant for flow rates from 0.5 to 2 mL min(-1). The calibrated sensors were subsequently used to demonstrate laterally resolved detection of oxygen inside a microfluidic channel. The fabrication process provides a novel, easy to use method for the repeatable integration of optical oxygen sensors into cell-culture and lab-on-a-chip devices.

Color controller integrates RGB photosensor

Avago Technologies has announced a color controller with an integrated color photosensor for backlighting LCDs, touted to be the industry's first such product. According to the company, the new ADJD-J823 enables more accurate and consistent RGB LED backlighting and richer colors than conventional technology. This solution is suitable for use in digital cameras, cell phones, PDAs, portable DVD players and display screens measuring 7 inches diagonal or smaller.
The device has a small footprint and low profile that allows it to easily fit into portable LCD devices where board space is limited, Avago said. The 5-by-5-by-0.75mm illumination and color management (ICM) device operates at voltages as low as 2.5V.
The new device is a CMOS mixed-signal IC with integrated RGB photosensors designed to be the closed loop optical feedback device of an RGB LED-based backlighting system. It also has a wide gain control and uses an algorithm to automatically select the optimum gain.
A typical system consists of an array of RGB LEDs, LED drivers and the color controller. The device samples the light output from the RGB LED array, processes the color information and adjusts the light output from the RGB LEDs until the target color is achieved. To do this, the device integrates an RGB photosensor array, an ADC front-end, a color data processing logic core and a high-resolution 12bit PWM output generator. By employing a feedback system and the color controller, the light output produced by the LED array maintains its color over time and temperature.
"By integrating the sensor and controller into one package, we are expanding the benefits of color management to the growing array of applications using color LCD screens in smaller consumer electronics," said Lee Soo Ghee, vice president and general manager for Avago's Optoelectronic Products Division.
Avago said the use of LED backlighting with the company's ICM control in LCD TVs has been proven to offer 25 percent richer colors than conventional cold cathode fluorescent lamp (CCFL) backlighting. In addition, LED backlighting totally eliminates the traces of mercury found in CCFLs to meet European Union RoHS mandates, the company said.

InGaP/GaAs heterojunction photosensor powered by an on-chip GaAs solar cell for energy harvesting

In this study, an InGaP/GaAs heterojunction phototransistor (HPT) and a GaAs solar cell were monolithically integrated into an HPT epitaxial wafer, and the battery-free operation of the HPT was demonstrated for energy harvesting. Although the thickness and doping condition of the layers were optimized for the HPT performance, but not for the solar cell performance, the obtained short-circuit current was high enough to operate the InGaP/GaAs HPT in a two-terminal (2T) configuration. A collector photocurrent of 0.63 mA was obtained when the energy-harvesting InGaP/GaAs 2T-HPT was exposed to white light with a power density of 35 mW/cm², and it linearly increased with the power density. For a potential application of the energy-harvesting InGaP/GaAs HPT as a photosensor in space, the device was irradiated with electrons of 1 MeV energy and 10¹⁵ cm⁻² fluence. No significant degradation of the fabricated energy-harvesting 2T-HPT after the high-energy electron irradiation guarantees its battery-free operation in space.

A heterojunction phototransistor (HPT) is more attractive as a photosensor than a photodiode because of its high photoresponse even at low bias voltage and immunity from avalanche noise. In particular, the GaAs-based HPT with an AlGaAs emitter demonstrated a high performance. Recently, the InGaP emitter has replaced the AlGaAs emitter in the AlGaAs/GaAs HPT owing to its superior material properties. The photosensor may be widely used in space, where it needs to be operated without a battery. An HPT has a process compatibility with a heterojunction bipolar transistor (HBT) for the fabrication of monolithically integrated photoreceivers. The InGaP/GaAs HPT also has good compatibility with the GaAs heteroface solar cell for a battery-free operation. Solar cells made of III–V compound semiconductors have been developed and used in space owing to their high conversion efficiency, lower temperature coefficient, and superior radiation resistance. The significant potential of high-efficiency GaAs heteroface solar cells for space applications has been extensively investigated by many researchers.Compared with Si, which has been widely used as a material of terrestrial solar cells, III–V compound semiconductors have a superior radiation resistance for the same electron energy and fluence. In particular, the InGaP solar cells demonstrated a radiation resistance superior to that of GaAs solar cells. Since the migration energy of radiation-induced defects and the activation energy of defect annealing in InGaP are lower than those in GaAs, InGaP has a higher radiation resistance than GaAs. In this study, radiation resistant InGaP was used as a window layer in a GaAs heteroface solar cell.
In space, high-energy electron or particle irradiation often induces a significant degradation of the performance of semiconductor devices. Since the battery-free operation of an InGaP/GaAs HPT monolithically integrated with a GaAs solar cell is also proposed for use in space in this paper, the effects of high-energy electron irradiation on the fabricated energy-harvesting HPTs were studied by 1 MeV electron irradiation.

Researchers develops toxic gas sensor that can connect to smartphones

Groups of researchers in Japan and the U.S. have jointly developed a material -- a coated carbon nanotube -- that could realize a low-cost, easy-to-carry toxic gas sensor that works with smartphones.
The researchers at the National Institute for Material Science (NIMS) in Ibaraki Prefecture and the Massachusetts Institute of Technology announced Thursday that the material is a carbon nanotube coated with insulating polymer.
Carbon nanotube is normally highly conductive, but the insulating polymer serves to significantly lower the tube's conductivity.
But the coated polymer breaks apart when it is exposed to toxic gases, in which case the conductivity of the tube drastically increases.
NIMS says it can make a sensor by loading this material in a chip that can exchange data wirelessly with smartphones in close proximity just like the Suica cards used for shopping or paying for train rides.
When toxic gas is present in the atmosphere, the material in the sensor becomes conductive, so if people hold their smartphones over the sensor, the handsets will react.
Shinsuke Ishihara, a senior researcher at NIMS, said the Japanese team explained that the toxic gas detectors currently used are heavy and expensive.
But with 1 gram of the new polymer, it is possible to make 4 million sensors, he said.
The researchers hope to put the material to practical use before 2020, and hope to install the sensors at public facilities and subway station to prepare for possible terrorist attacks such as one perpetrated by the Aum Shinrikyo religious cult in the Tokyo subway system in 1995 using sarin nerve gas.
The researchers are thinking of establishing advanced systems, such as one that can automatically send signals to smartphones whenever toxic gases are detected, Ishihara said.
The sensors can be also attached directly to smartphones, Ishihara added. If there is a smartphone app that can automatically check sensors once every few seconds, it can be used to monitor toxic gases in real time.
MIT researchers in the meantime are hoping to use the sensors to design lightweight radio-frequency identification badges that could be worn by soldiers on the battlefield, according to the MIT website.

Low-cost miniaturized UV photosensor for direct measurement of DNA concentration

Highly sensitive measurement of DNA concentration on portable, easy-to-use, low-cost miniaturized equipments without sample waste is challenging.
The DNA peak optical absorbance at λ=260 nm is a well-known property already used in the spectrometric measurement of DNA concentration. Existing apparatus are large-sized, expensive and require a manipulation of DNA. In the current work, a low-power, suitable and miniaturized photosensor aiming at a sensitive and direct measurement of DNA concentration has been designed. Direct measurement, i.e. without sample manipulation, implies UV transmission through the translucid tube wall from the closed tube containing the DNA sample in solution.
To allow measurements at such low wavelengths, we designed and fabricated photodiodes in SOI technology to ensure a high responsivity in the UV range. Measurements of the photodevice confirmed its responsivity spectrum and magnitudes. These fully integrable photodiodes, fabricated in SOI CMOS technology, can be coupled to a complete signal processing microsystem.
Direct measurements at 280 nm optical wavelength of serially diluted DNA within a closed tube (range: 40 pg/μL to 400 ng/μL in a volume of 45 μL) generated a monotonic relation between the DNA concentration and the mean of the diode photocurrent induced by light transmission through DNA solution and tube container. Absorbance of the incident UV ray was inversely proportional to DNA concentration. The photosensor compared favorably with other DNA quantitative methods (spectrophotometry, fluorometry, real-time PCR) in terms of sensitivity.
Originalities of this work are the use of a thin-film SOI photosensor, the low-cost, portable and adaptable system and the potential of the device for direct measurement of nucleic acid concentration within tube containers without sample manipulation or waste.

Apple could use curved photosensors to product smaller iPhone cameras

A new Apple patent reveals the Cupertino company could soon employ curved photosensors to create smaller iPhone cameras that capture better photos. The design could help Apple in its mission to make future smartphones even thinner.
Published by the U.S. Patent and Trademark Office this week, “Small form factor high-resolution camera” describes a cutting-edge mobile camera module that uses complex optics to deliver a more compact footprint and even better performance.
Apple explains how the sensor could refract light through a trio of special lenses onto a concave surface, resulting in a sharp, low-distortion image. The company also notes that the curved array limits diffraction, allowing the use of a smaller sensor with smaller pixels.
“To correct for diffraction and visual aberrations that propagate within miniature cameras, the proposed lens system includes three lenses, two of which are convex or substantially convex,” explains AppleInsider. “A third meniscus lens, or a lens with opposing convex and concave surfaces, is situated between the first two lens elements and the spherical photosensor.”
The design does have its limitations, however, such as barrel distortion. Apple describes how it might use software to correct unwanted effects like this.
Such sensors could allow Apple to make the iPhone thinner, or ensure future sensors sit flush with the handset’s case — rather than protruding out of it like they do with iPhone 6 and iPhone 6s. It could also lead to better cameras in the iPad, and even cameras in devices like Apple Watch.
But as always, Apple patents are never a guarantee of things to come, so this particular invention may never see the light of day.

Toshiba Matsushita Display Develops Photosensor Touch-Panel

Toshiba Matsushita Display Technology Co., Ltd. (TMD) has developed an LCD panel that enables finger-touch input using photosensors under a range of light conditions from dark indoor to bright outdoor. Through enhanced sensitivity of the photosensors integrated onto the LCD panel's glass substrate and optimized signal processing functions, the panel detects reflection from a finger using backlight in dark indoor and finger shadows using external light in bright outdoor.

The prototyped panel is a transmissive LCD panel using a 2.8-inch (7.1 cm diagonal) WQVGA (400 x 240 pixels) resolution, low-temperature polycrystalline Si (p-Si) TFT with approximately 65,000 display colors. The range of ambient light intensity, in which finger-touch input is available, extends from 0 to 100,000 lx.

The panel has become able to recognize finger-touch input in a wide range of light intensity by switching its recognition modes between finger shadows using external light and finger reflections using its built-in backlight depending on the situation. The panel not only recognizes finger shadows but also supports input using an optic pen. TMD will present this panel at the Flat Panel Display International (Display 2007) show to be held at Tokyo Big Sight from April 11 to 13.
