    摘要: A method, apparatus, and system are described in which a signal is generated to inhibit the execution of flip commands that cause a flip between buffers of a frame buffer. One or more of the flip commands and their associated instruction pointers may be preloaded into a frame buffer flip queue prior to removing the signal inhibiting the execution of the flip commands.

    摘要: In an encoding process, video data are represented as a bitstream of quantized base data and enhancement data, which capture the difference between a quantized base video picture and an original unquantized input video picture. Due to bandwidth constraints on a communication channel, it may be unfeasible to transmit all enhancement data. During the encoding process, the enhancement data may be divided into “layers” based upon bandwidth restrictions. Following transmission, the layers are recombined and are added to the base data by a decoder, producing a viewable video sequence.

    摘要: A control system for an electric motor used to provide mechanical power to a power steering system in a vehicle. The motor is of the two-phase type with an independent winding for each phase, or of the three-phase type with two independent stator windings. Two inverters are provided, one for each winding. Each inverter provides AC current to run the motor. If a fault is detected in an inverter or its stator winding, current is terminated to that inverter, and the motor is run using the other winding. In addition, if the vehicle battery is installed with incorrect polarity, components within the inverters can be destroyed. The invention detects the incorrect polarity, and blocks current to the inverters.

    摘要: An apparatus and method for controlling sinusoidal currents in inductive loads during zero-crossing to reduce distortion. The apparatus and method utilizes first and second PWM signals during a single PWM cycle to apply opposite voltage signals to obtain a net desired voltage across the inductive load. The voltage applied to the load is compared with a threshold and, when the applied voltage is greater than the threshold, normal PWM signals are applied to the load, and when the applied voltage is less than the threshold, an adjusted voltage formed of first and second PWM signals is applied to the load.
