Abstract: Light sensors having a wide dynamic range are used in a variety of applications. A wide dynamic range light sensor includes an exposed photodiode light transducer accumulating charge in proportion to light incident over an integration period. Sensor logic determines a light integration period prior to the beginning of integration and the charge is reset. Charge accumulated by the exposed light transducer over the light integration period is measured and a pulse having a width based on the accumulated charge is determined.

Abstract: A substrate for a photoelectric conversion device that is effective in trapping light in a photovoltaic layer and can be manufactured by industrial mass-production, a method of manufacturing the same, and a photoelectric conversion device using the same. On a glass sheet containing an alkaline component, a first undercoating film containing tin oxide as a main component, a second undercoating film, and a conductive film containing tin oxide as a main component are formed in this order, thus obtaining a substrate. The first undercoating film is formed by a thermal decomposition oxidation reaction of coating-film forming materials containing chlorine on glass with a temperature of at least 600° C. In the first undercoating film, holes are formed without an after-treatment. The surface of the conductive film above the holes has larger irregularities, thus scattering incident light on a photovoltaic unit. Further, on the photovoltaic unit, a back electrode is formed, thus obtaining a photoelectric conversion device.

Abstract: An infrared (IR) transceiver having a receiver chain with an isolated analog output, includes a transmission gate and a unity gain buffer interposed between the amplifier output and an analog output pad. The transmission gate behaves as a switch, passing the analog output signal to the analog output pad only when an analog output is required. The unity gain buffer has a high input resistance, a low input capacitance, a unity gain and a low output impedance, so that the load of a digital signal processing (DSP) device or measuring instrument on the analog output pad is isolated and does not affect the performance of the receiver chain. Since the transfer rates of the transmission gate and the buffer are each unity, the analog output pad provides a high fidelity analog output signal to the output buffer.

Abstract: In a video receiver, a photodiode is terminated with one or more junction diodes to provide an output voltage that is a log function of the incident optical power. The termination with the diode provides a nonlinear resistance which converts the output current of the photodiode to a voltage, with the output voltage being the log of the input current due to the nonlinear resistance characteristic associated with junction diodes. The subject system eliminates the necessity of providing a transimpedance amplifier used to obtain a voltage from the photo current of a photodetector and also the requirement for a log amplifier to provide the log of the voltage to give the receiver a wide dynamic range. In one embodiment a PIN diode is provided with a series of termination diodes, with the larger of the number of diodes, the more voltage that is available. The series-connected termination diodes provide a passive low noise system for converting the photo current to a log voltage.

Abstract: An optical detector is formed so that gate traces formed during molding of a lens member do not allow additional stray light to enter a light detecting element. A lens member for focusing incident light is mounted forward of a cylinder used for blocking extraneous light. An IC light detecting device used for range-finding is mounted behind the cylinder. The lens member has lens portions and a peripheral portion surrounding the lens portions. The lens portions and the peripheral portion are integrally molded from a transparent plastic material. Positioning protrusions extend from an outer peripheral surface of the lens member. Recessed portions in which the positioning protrusions can be engaged are formed in a front outer peripheral portion of the cylinder. Gate traces formed during molding are located in the positioning protrusions. Consequently, additional recessed portions are not needed to accommodate the gate traces.

Abstract: An optical navigation system saves power by pulsing its surface illumination light source to provide light only when needed. The level of light may be controlled by a servo-mechanism that monitors degree of correlation data and average illumination, and that changes the controlled level at times when it is both required and safe to do so. As for creating different levels of illumination, that maybe accomplished by: (1) pulsing the light on and then opening the electronic shutter for some period of time during the pulse (gating the light); (2) opening the shutter and then varying the pulse width of the light (gating the LED); (3) opening the shutter and then pulsing the LED at different intensities; and (4) a combination of(2) and (3). In addition, the velocity of the navigation circuit over the surface (or vise versa) can be determined, and in cases where it is safe to assume that limited acceleration is possible, at low velocities it is desirable to reduce the rate of data acquisition, and thereby pulse the light source less often and conserve power.
