摘要： In the field of imaging, various components may contribute to a loss in resolution at higher spatial frequencies, both horizontally and vertically. Higher spatial frequencies may occur at the edge of an image, where there may be a large transition in the signal output between adjacent pixels. To compensate, an edge enhancement method that produces overshoots in the transitions of the video image signal is used. One of the problems with the edge enhancement method is that the noise in the input signal may not be adequately suppressed. To suppress the background noise in the video image signal while still performing the desired edge enhancement function, biasing circuitry may be used to suppress the smaller transitions in the input signal. In particular, the biasing circuitry may be placed in the signal path between the output of a first delay line and the noninverting inputs of two of the signal amplifiers. In this manner, the smaller transitions in the signal which represent background noise may be suppressed, while the edges of the video image signal are still enhanced.

摘要： A method of making high voltage complementary bipolar and BiCMOS devices on a common substrate. The bipolar devices are vertical NPN and PNP transistors having the same structure. The fabrication process utilizes trench isolation and thus is scalable. The process uses two epitaxial silicon layers to form the high voltage NPN collector, with the PNP collector formed from a p-well diffused into the two epitaxial layers. The collector contact resistance is minimized by the use of sinker up/down structures formed at the interface of the two epitaxial layers. The process minimizes the thermal budget and therefore the up diffusion of the NPN and PNP buried layers. This maximizes the breakdown voltage at the collector-emitter junction for a given epitaxial thickness. The epitaxial layers may be doped as required depending upon the specifications for the high voltage NPN device. The process is compatible with the fabrication of low voltage devices, which can be formed by placing the sinker regions under the emitter region. The thicknesses of the two epitaxial layers may be adjusted as required depending upon the specifications for the low voltage devices.
摘要翻译：在公共衬底上制造高电压互补双极和BiCMOS器件的方法。双极器件是具有相同结构的垂直NPN和PNP晶体管。制造工艺利用沟槽隔离，因此是可扩展的。该工艺使用两个外延硅层来形成高压NPN集电极，PNP集电极由扩散到两个外延层中的p阱形成。通过使用在两个外延层的界面处形成的沉降片上/下结构来最小化集电极接触电阻。该过程使热预算最小化，因此最小化NPN和PNP埋层的向上扩散。对于给定的外延厚度，这使集电极 - 发射极结处的击穿电压最大化。外延层可以根据需要掺杂，这取决于高压NPN器件的规格。该工艺与低电压器件的制造兼容，这可以通过将沉降片区域放置在发射极区域下而形成。根据低电压器件的规格，可以根据需要调整两个外延层的厚度。

摘要： A method of fabricating a switching element or a matrix of switching elements includes providing a waveguide substrate having at least two waveguides that intersect at a trench such that optical coupling between the waveguides is dependent upon the presence or absence of an index-matching fluid at the intersection of the waveguides with the trench. Fluid is supplied to the trench via a fluid fill-hole that extends through a heater substrate in a direction that is generally perpendicular to a substrate surface on which at least one heater is fabricated. In the preferred embodiment, the fluid fill-hole is formed in a step of inductively coupled plasma (ICP) reactive ion etching (RIE). The waveguide substrate having at least two waveguides and the heater substrate having the heaters and the fill-hole are bonded together after the substrates are aligned such that the trench is in fluid communication with at least one fluid fill-hole and is in thermal communication with at least one heater. Optical fibers are then coupled to the waveguides. Preferably, a structurally weakened edge portion is formed during the ICP RIE step so that the edge portion can be removed after the two substrates are bonded, allowing uninhibited access of the optical fibers to the waveguides.

摘要： Disclosed is a system to forecast a supply of online advertising demand contracts having day parting targets. The system may receive an online advertising demand contract having a flight duration and a day parting target. The received online advertising demand contract may be processed by converting the day parting target into an hour-of-week day parting target vector. If a first day of the flight duration would generate a conflict in view of the hour-of-week day parting target vector, then the system may generate a new first day contract for the first day of the flight duration.

摘要： An optical memory having an input port for receiving an input optical signal to be stored in the optical memory is disclosed. A portion of the optical signal is coupled to a storage loop for storing optical signals by a coupler that transfers a portion of the input optical signal to the storage loop. An optical signal stored in the storage loop is output by coupling a portion of that optical signal to a first external optical waveguide. The storage loop includes a semiconductor optical amplifier for amplifying the signals stored in the storage loop to compensate for losses incurred by those signals in traversing the storage loop. A plurality of such optical memories can be combined to form a larger memory that includes a reconditioning circuit that resets the amplitude of the optical signals to a value that depends on the amplitude of the optical signals.

摘要： An optical switch that includes optical paths organized into a set of M input optical paths and a set of N output optical paths, where at least one of M and N is greater than unity. The optical switch additionally includes a faceted mirror corresponding to each of the M input optical paths and including N facets and a faceted mirror corresponding to each of the N output optical paths and including M facets. Finally, the optical switch includes a moving mechanism coupled to each faceted mirror to step the faceted mirror linearly in a direction orthogonal to the optical paths to selectively align one of the facets of the faceted mirror with the one of the optical paths with which the faceted mirror is associated. The facets of each of the faceted mirror corresponding to one of the sets of optical paths, i.e., the set of input optical paths or the set of output optical paths, are preferably angled to reflect light towards a different one of the faceted mirrors corresponding to the other of the sets of optical paths, i.e., the set of output optical paths or the set of input optical paths, respectively.

摘要： An improved active pixel sensor soft reset circuit for reducing image lag while maintaining low reset kTC noise. The circuit pulls down the sensor potential to a sufficiently low level before the soft reset function is completed. The level to which the sensor potential is pulled is set between 0 and the critical potential at which the reset transistor will be on when the soft reset function begins. The timing of the pull down function is such that the sensor is stabilized at the low potential before the soft reset function completes. In one embodiment, the sensor potential is pulled down using a pull-down circuit, which may consist of a CMOS type inverter. In another embodiment, the sensor potential is pulled down by the bit line. Two ways in which the bit line may be pulled down are natural discharge, or by increasing the bias on the loading transistor. Two ways in which the bias on the loading transistor may be increased are a biasing circuit, or by using a pull-down transistor. The active pixel sensor may be implemented with any suitable sensor technology, such as photodiode, photogate, or pinned diode.
