摘要： A system includes a monitoring module, a congestion module, a modification module, and a communication module. The monitoring module monitors vehicles in a transportation network. The congestion module calculates a throughput parameter that is representative of a statistical measure of adherence to a movement plan by the vehicles. The modification module determines a confidence parameter representative of a probability that changing the original meet event does not reduce the throughput parameter. The modification module modifies the original meet event to an updated meet event when the confidence parameter exceeds a predetermined threshold. The communication module transmits the updated meet event to the yielding vehicle and/or the passing vehicle, for the yielding vehicle and/or the passing vehicle to receive the updated meet event from the communication module and change a speed of the yielding vehicle or the passing rail vehicle to arrive at the updated meet event.

摘要： The present invention provides a CMOS imager with a reset scheme, by which a CMOS imager generates a sub-kTC noise so that read noise does not depend on the sense node capacitance. By using a column feedback circuit, reset noise can be suppressed to a negligible amount so that photogate APS or CCD-like circuits can achieve noise performance to very efficient value. This scheme allows increasing sense node capacitance without increasing the noise and also achieves a large full-well value without sacrificing read noise performance. The feedback circuit in one of the embodiment of the present invention is located at the column side of the circuit. This design provides a minimal change to the pixel. As a result quantum efficiency or pixel size is not compromised. The present invention allows a CMOS imager to capture scene with high intra-scene contracts under low illumination with high dynamic range.

摘要： For a source-follower signal chain, the ohmic drop in the selection switch causes unacceptable voltage offset, non-linearity, and reduced small signal gain. For an op amp signal chain, the required bias current and the output noise rises rapidly with increasing the array format due to a rapid increase in the effective capacitance caused by the Miller effect boosting up the contribution of the bus capacitance. A new switched source-follower signal chain circuit overcomes limitations of existing op-amp based or source follower based circuits used in column multiplexers and data readout. This will improve performance of CMOS imagers, and focal plane read-out integrated circuits for detectors of infrared or ultraviolet light.

摘要： A multiple-step reset process and circuit for resetting a voltage stored on a photodiode of an imaging device. A first stage of the reset occurs while a source and a drain of a pixel source-follower transistor are held at ground potential and the photodiode and a gate of the pixel source-follower transistor are charged to an initial reset voltage having potential less that of a supply voltage. A second stage of the reset occurs after the initial reset voltage is stored on the photodiode and the gate of the pixel source-follower transistor and the source and drain voltages of the pixel source-follower transistor are released from ground potential thereby allowing the source and drain voltages of the pixel source-follower transistor to assume ordinary values above ground potential and resulting in a capacitive feed-through effect that increases the voltage on the photodiode to a value greater than the initial reset voltage.

摘要： A two-dimensional range-imaging system is capable of transmitting light from a source into a field of view and focusing return portions of the light, reflected off targets in the field of view, onto a two-dimensional array of photodetectors. The photodectectors convert the return portions of light into electric signals that are compatible with a solid state circuit. Each electric signal is combined with a one or more reference signals to indicate a distance between the source and an associated target.
