摘要： A computer based method for estimating surface velocity based on a time series of at least two images of a same portion of the ocean surface by solving a heat equation having unknown parameters of heat source s and surface velocity components u and v. The images can be infrared or thermal images from the AVHRR or other images. Assign a pattern of sub-arrays with number of pixels in each sub-array sufficient to overdetermine the heat equation without the need to apply divergence and vorticity constraints. Define the heat equation for each interior pixel using bilinear interpolation at each interior based on solutions at the corner pixels. Use linear regression to solve for the unknown parameters u, v, and s for each corner pixel by minimizing total error of the heat equation in finite difference form at all pixels, and find the parameters at each remaining point with bilinear interpolation.

摘要： A video-rendering chip performs gain correction on received display input, based on a display temperature, to produce output values that are shown on the display. The video-rendering chip includes multipliers, a microprocessor, and a memory. The microprocessor receives a display temperature from a sensor, determines gain correction coefficients that correspond to the display temperature, and provides the correction coefficients to the multipliers. The multipliers then multiply the display input by the correction coefficients to produce the output values. The microprocessor may determine the correction coefficients utilizing a lookup table or a correction coefficient formula stored in the memory. The microprocessor may receive an updated display temperature periodically and may determine new correction coefficients that correspond to the updated display temperature. The microprocessor may receive updated display temperatures at fixed periods or at varying periods based on the previous display temperature.

摘要： A method for ensuring reliable transmission of a DCN signal by a gateway is disclosed. When acting as a sending gateway, the gateway packs a DCN signal detected into an IFP packet and sends the IFP packet to the IP side, then, reports a fax end event to a Soft Switch after a designated delay period; and the Soft Switch issues a State Switching Command for switching the two gateways back to voice state after receiving the fax end event. When acting as a receiving gateway, the gateway modulates a DCN signal detected and sends the modulated DCN signal to a receiving facsimile machine; if a switching command issued by a Soft Switch is received during sending the DCN signal, the gateway delays the switching; if the gateway has not received a switching command after the DCN data is sent, the gateway initiatively reports a fax end event.

Each string may include light emitting diodes from a different color bin, and the respective driving strengths may be adjusted, for example, through pulse width modulation or amplitude modulation, to maintain the target white point. In certain embodiments, the driving strengths may be adjusted to compensate for shifts in the white point that may occur due to temperature or aging.
