摘要： A demodulator, suitable for use in a communication system and in a modem, has a block polyphase circuit with circuit blocks for different signal processing functions, particularly filtering, delay, and frequency conversion. The circuit blocks are arranged for parallel processing of different portions of an input sequence of signals. Signals of the input sequence to be filtered are divided among the blocks by a demultiplexer for processing at a clock frequency lower than a clock frequency of the input signal sequence. Signals outputted by groups of the circuit blocks are summed to produce an output signal of the group. Frequency and timing reference signals, as well as fractional delay interpolation, are produced also by parallel-channel circuitry. Output signals of all of the groups are multiplexed to provide an output signal sequence such that the repetition frequency of the outputted signals may be higher, lower, or equal to that of the input signal sequence. This enables use of programmable circuitry operative at clock rates lower than rates required to process directly the input signal sequence.
摘要翻译：适用于通信系统和调制解调器的解调器具有块多相电路，具有用于不同信号处理功能的电路块，特别是滤波，延迟和频率转换。电路块被布置用于对输入信号序列的不同部分进行并行处理。要被滤波的输入序列的信号由解复用器在块之间划分，以在低于输入信号序列的时钟频率的时钟频率处理。将由电路块的组输出的信号相加以产生该组的输出信号。频率和定时参考信号以及分数延迟插值也由并行通道电路产生。所有组的输出信号被复用以提供输出信号序列，使得输出信号的重复频率可以高于，低于或等于输入信号序列的重复频率。这使得可以使用以低于直接处理输入信号序列所需的速率的时钟速率工作的可编程电路。

摘要： A ventilated toilet for removing odors from the toilet base includes a unitary molded tank assembly with an integral ventilation cavity formed along the base and the back inside of the water tank. At least one water channel connects a water inlet chamber of the base to the water tank and is configured to channel water into the base when released from the tank, as well as to provide an airflow conduit for odors present in the base to be removed from the base via the ventilation cavity. A flush valve extends through the ventilation cavity to connect the tank and the base, and is sealed in attachment to eliminate egress of odors. The system permits substantial elimination of odors at flush volumes of 1.6, 1.3 or 0.8 gallons per flush by virtue of the enhanced seals and unitary construction. A toilet tank assembly in accordance with the invention is also disclosed.

摘要： A closure for pipeline pig sender or receiver includes a primary closure body and a secondary closure body. The primary closure body has an outer face, an inner face and a port extending therethrough from the outer face to the inner face. The primary closure body is secured to the pipeline pig sender or receiver sealing a closure end when the primary closure body is in the closed position. The secondary closure body closes the port on the primary closure body. The secondary closure body is movable between a closed position and an open position to enable an operator to insert a tool through the port into the diversionary passage to manipulate the pipeline pig and release trapped pressure prior to opening the closure. The secondary closure body is secured to the primary closure body sealing the port when the secondary closure body is in the closed position.

摘要： Air cleaner assemblies and components therefor are described. An example first or main filter cartridge is described which includes a media pack comprising strips of fluted material secured to facing sheets, oriented in a stack. The media pack defines opposite inlet and outlet flow faces, with flutes extending in a direction therebetween. The media pack is non-removably secured within a filter cartridge housing, at a location between opposite sections of a shell, typically secured thereto with an adhesive. The shell also defines a closed end, spaced from, but in overlap with, the outlet end face of the media pack. The closed end is typically curved and the shell typically provides either a d/b-shape or a u-shape. The filter includes an end member, with a outlet flow aperture arrangement therein, allowing for outlet flow from the filter cartridge in a general direction orthogonal to air flow through the media pack. The air cleaner assembly includes a housing having features for receipt of, and engagement by, the filter cartridge. An optional secondary filter cartridge is provided, mountable on the housing in an orientation projecting into a clean air volume in the main filter cartridge.

摘要： A Static Random Access Memory (SRAM) having a split write control is described. The SRAM includes bit, write, and write-word lines. Each memory cell within the SRAM includes a delay which is coupled to a dedicated write-word line. When a cell is not being written, its delay receives a delay signal on its associated write-word line, which increases the response time of the cell. When a cell is to be written, however, its delay receives a bypass signal on its associated write-word line, which decreases the response time of the SRAM cell.
摘要翻译：描述具有分离写入控制的静态随机存取存储器（SRAM）。 SRAM包括位，写和写字线。 SRAM内的每个存储单元包括耦合到专用写字线的延迟。当单元未被写入时，其延迟在其相关联的写字线上接收延迟信号，这增加了单元的响应时间。然而，当单元被写入时，其延迟在其相关的写字线上接收旁路信号，这降低了SRAM单元的响应时间。
