摘要： A frame synchronizer having broad applicability in television systems is particularly adapted for use in a chrominance time-compressed, luminance bandwidth reduced television system. The frame synchronizer, which separates the composite video signal into its component parts and thereby minimizes the dynamic range required to digitize the signal, demodulates the chrominance signal into its quadrature components and separates the luminance signal. The synchronization signal in the composite video signal generates slave distribution signals and slave horizontal and vertical addresses. The separated chrominance quadrature components and the luminance signal are digitized and, along with the slave distribution signals and the slave horizontal and vertical addresses, are temporarily stored in first-in, first-out memories which provide independent buffering and thereby accommodate a high degree of mismatch between master and slave timing. The chrominance and luminance data are accumulated in distribution registers and transferred to write registers which provide the data input to a frame buffer memory. Master distribution and master horizontal and vertical addresses are generated from a master synchronization signal along with write and read control signals. The data in the write register is read into the frame buffer memory at the slave horizontal and vertical addresses in response to the write control signal, and data in the frame buffer memory is read out from the master horizontal and vertical addresses in response to the read control signal, converted to analog signals, and combined to form a composite signal.
摘要翻译：在电视系统中具有广泛适用性的帧同步器特别适用于色度时间压缩，亮度带宽降低的电视系统。帧同步器将复合视频信号分离成其组成部分，从而使信号数字化所需的动态范围最小化，将色度信号解调为其正交分量并分离亮度信号。复合视频信号中的同步信号产生从属分配信号和从属水平和垂直地址。分离的色度正交分量和亮度信号被数字化，并且与从属分布信号和从属水平和垂直地址一起临时存储在提供独立缓冲的先进先出存储器中，从而适应高度主从时间不匹配。色度和亮度数据被累积在分配寄存器中，并被传送到向RAM缓冲存储器提供数据输入的写入寄存器。主分配和主水平和垂直地址由主同步信号以及写和读控制信号产生。写入寄存器中的数据响应于写入控制信号被读入到从属水平和垂直地址的帧缓冲存储器中，并且响应读取从主水平和垂直地址读出帧缓冲存储器中的数据控制信号，转换为模拟信号，并组合形成复合信号。

摘要： A simple digital filter having only a single multiplier operates to extract the pilot tone from a demodulated and digitized FM stereo signal. The number of poles in the filter is chosen so that the filter output is also usable to produce a digitized representation of the carrier tone for the left minus right stereo channel. This signal is in turn used to decode the input representation into the desired left and right channel signals. The circuit of the present invention is particularly amenable to fabrication on an integrated circuit chip.

摘要： A reconfigurable remote control transmitter is disclosed that has the ability to learn, store and repeat the remote control codes from any other infrared transmitter. The reconfigurable remote control transmitter includes an infrared receiver, a microprocessor, nonvolatile and scratch pad random access memories, and an infrared transmitter. The microprocessor application is divided into four main categories: learning, storing, retransmitting, and user interface. In the learning process, the reconfigurable remote control transmitter receives and decodes the transmissions from another remote control transmitter. The process is repeated at least twice for each key to make sure that it has been properly received and decoded. Once the data has been received and decoded, it is stored for later use. In order to do this, the received and decoded data is compressed so that it can fit into the nonvolatile memory. This process is repeated for each of the several remote control transmitters that are to be replaced by the reconfigurable remote control transmitter. When the learning and storing operations have been completed, the reconfigurable remote control transmitter is ready to use.

摘要： A tracking apparatus identifies distorted output signals from a digital system caused by at least one distorted signal input to the digital system. A first signal is input to the tracking apparatus when a distorted signal is input to the digital system. A second signal is input to the tracking apparatus when a non-distorted signal is input to the digital system. The tracking apparatus models a delay and widening characteristics of the digital system and operates in parallel with the digital system.

摘要： A system for sensing spin speed and an out-of-balance condition in a washing machine is provided. The washing machine includes a washer basket and an agitator that spin about a predetermined spin axis during a spin cycle. The OOB condition can be characterized by excursions, during the spin cycle, of a tub which encloses the washer basket. The tub excursions can be in a direction generally perpendicular to the spin axis of the washer basket, for example. The system includes a magnetic source, such as a permanent magnet, positioned in the agitator for producing a predetermined magnetic field. A magnetic sensor is positioned to be electromagnetically coupled to the magnetic source for supplying an output signal that varies as the agitator rotates relative to the magnetic sensor. A signal processor is coupled to the magnetic sensor for receiving the output signal supplied by the magnetic sensor. The processor is programmed for measuring spin speed during the spin cycle and for detecting any out-of-balance condition during the spin cycle based on the variations of the output signal received from the magnetic sensor.

摘要： A time domain technique for implementing an adaptive wall filter improves imaging of low-velocity blood flow by removing signals associated with slowly moving tissue. Adaptive wall filtering is performed by estimating wall velocity and bandwidth, and then filtering the basebanded data with a complex time domain notch filter. The wall velocity estimate determines the center frequency of a wall signal while the wall variance estimate determines the wall signal bandwidth. The complex filter coefficients selected are those which will center the complex notch filter on the wall center frequency, and which will set the filter cutoff frequencies (measured from this center frequency) to match the wall signal bandwidth.

A color flow processor includes a time domain adaptive wall filter which automatically adjusts to changes in frequency and bandwidth of the wall signal components in the focused baseband echo signals.
