摘要： Predetermined data is stored in first and second predetermined locations of a memory. The first location may be in a first part of the memory, and the second location may be in a redundant part of the memory. At power up or reset, the first predetermined location of the memory successively is read and compared to data stored in a register until the comparison indicates a match for a predefined number of consecutive reads and comparisons. The successive reading may be stopped if the number of comparisons indicating a failure equals another predefined number of times. The data stored in the second predetermined location also is read. This data may be compared to the data previously read from the second predetermined location. The reading and comparing from the first predetermined location and the reading from the second predetermined location are continued until the number of times data is read from the second predetermined location equals a third predetermined number. The voltage signal is then determined to be valid after sufficient successive reads of the first predetermined location of the memory.

摘要： A reprogrammable fuse has a pair of non-volatile memory cells differentially programmed. The pair of non-volatile memory cells are connected to a pair of bitlines and through a pair of switches to a precharging voltage. The switches are controlled by a precharging and equalization signal, which when activated, serves to precharge the bitlines. The charged bitlines are then connected to the pair of differentially programmed non-volatile memory cells and one of the bitlines is discharged faster than the other. The resultant output is taken from one of the bitlines.

摘要： A multimedia distribution network combines the flexibility of digital video and digital networks with the low cost, high bandwidth, and isochronous capabilities of analog video distribution. At the heart of the network is a hybrid digital/analog multimedia hub, called a C-box, which provides connectivity to digital networks, both local area and wide area, with the necessary video compression and decompression, composition engines for multiple video streams and analog/digital conversions of the multiple video streams for connectivity to an analog video distribution network for delivery to end user workstations. The C-box receives multiple compressed digital video streams, decompresses the video streams, converts the decompressed video streams to analog, and delivers the converted analog signals to workstations via an analog cable television (CATV) network. The amount of video processing (e.g., compression and decompression) power required is proportional to the number of active video streams instead of the number of attached end user workstations. The analog channels over which the converted analog signals are transmitted are dynamically allocated, and once the analog signals have been transmitted to a requesting client terminal, the channels are released for reuse.
摘要翻译：多媒体分发网络将数字视频和数字网络的灵活性与模拟视频分发的低成本，高带宽和同步功能相结合。网络的核心是混合数字/模拟多媒体集线器，称为C盒，它提供与数字网络（包括局域和广域）的连接，具有必要的视频压缩和解压缩，用于多个视频流的组合引擎，用于连接到模拟视频分配网络的多个视频流的模拟/数字转换，以传送到最终用户工作站。 C盒接收多个压缩数字视频流，解压缩视频流，将解压缩的视频流转换为模拟，并通过模拟有线电视（CATV）网络将转换的模拟信号传送到工作站。所需的视频处理量（例如，压缩和解压缩）的功率与活动视频流的数量成比例，而不是连接的最终用户工作站的数量。转换的模拟信号被传输的模拟通道被动态地分配，一旦模拟信号已被发送到请求客户终端，则信道被释放以供重用。

摘要： An electrical connector comprising at least one electrical contact; and a housing connected to the contact. The housing has at least two housing pieces comprised of ultrasonically weldable material. A first one of the housing pieces has grooves. A second one of the housing pieces has projections located in the grooves. At least one of the projections comprise an energy director leading section which has a general cross-sectional wedge shape before ultrasonic welding of the first and second housing pieces to each other for use in directing energy during ultrasonic welding.
