Abstract: A lock in pinned photodiode photodetector includes a plurality of output ports which are sequentially enabled. Each time when the output port is enabled is considered to be a different bin of time. A specified pattern is sent, and the output bins are investigated to look for that pattern. The time when the pattern is received indicates the time of flight.

Abstract: A pinned photodiode is operated without a transfer gate. This is done by forming a pinned photodiode which has a selective connection to the substrate. When the connection is turned on, the photodiode is pinned to the substrate, and kept at a specified potential. When the connection is off, the photodiode is disconnected from the substrate and hence floats. In this way, the area above the photoreceptor can be used both for a reception area and for a charge transfer area.

Abstract: A new kind of pixel is formed of two floating diffusions of different sizes and different conductivity type. The two floating diffusions have different image characteristics, and hence form a knee-shaped slope.

Abstract: An analog to digital converter oversamples an image signal, and uses the oversampled information to obtain additional resolution. The analog to digital converter is included in an image sensor device having a photosensor array of photosensitive of pixels and a plurality of analog to digital converters. Each of the analog to digital converters is adapted to produce a digital output with a first specified bit resolution. An interpolator is adapted to receive an output thus produced from an analog to digital converter and produce a digital output with a second specific bit resolution.

Abstract: A digital imaging system, such as an active pixel sensor (APS) system, includes an array of sensors arranged into lines that form rows and columns. Each sensor in the array includes a photosensor that collects electric charge when exposed to light. Each sensor also includes a select circuit that generates an output signal indicating the amount of charge collected by the photosensor during a given time, and a reset circuit that clears collected charge from the sensor at a selected time. The APS system also includes a line decoder circuit that produces select and reset signals and delivers the signals to the select circuits over control lines. Each control line connects to two adjacent lines, e.g., rows or columns, of the array, delivering a select signal to the image sensors in one of the two lines and delivering a reset signal to the image sensors in the other line.

Abstract: The present invention has found that the Mts1 protein is expressed in white matter astrocytes in the spinal cord. Such expression is significantly increased following sciatic nerve injury or dorsal root injury, particularly in astrocytes surrounding dorsal funiculus containing the central processes of the injured primary sensory neurons. The present invention has further demonstrated that Mts1 proteins administered extracellularly promote neurite outgrowth from neuronal cells. Based on these surprising findings, the present invention provides compositions and methods that are useful for the treatment of various neurological conditions characterized by death, degeneration or injury of neuronal cells.

Abstract: A CMOS image sensor obtains color through the use of two or three superposed layers. Each pixel in the image sensor includes a plurality of superposed photosensitive p-n junctions with individual charge integration regions. The combination of each of the superposed layers provides increased sensitivity and resolution of a single chip color imager.

Abstract: An oversampling A to D converter device. A succesive approximation A to D converter system is used with a relatively small size, and low resolution succesive approximation A to D converter. This converter is operated at a higher speed to obtain multiple samples and obtain additional bits of resolution from said multiple samples. Another aspect adds noise to the circuit, to cancel out noise.

Abstract: A CMOS Active Pixel Sensor (APS) uses a pinned photodiode as a photoreceptor and negative-channel metal-oxide semiconductor (NMOS) transistors in the sample and hold and reset circuits of the frame shutter. The pinned photodiode increases the quantum efficiency and reduces the dark current. The NMOS transistors in the frame shutter increase the fill factor and reduce the pixel pitch.

Abstract: A fully depleted photodiode accumulates charge into both the diode and a separate floating diffusion. The floating diffusion has less capacitance that the overall diode, thereby resulting in a knee-shaped transfer characteristic for charge accumulation. The fully depleted photodiode also include two PN junctions, one near the surface and the other buried below the surface.
