    摘要: Techniques of selective demodulation of downlink frames using a subscriber description segment or activity descriptor to identify one or more subscriber stations to which at least a portion of data placed in the downlink frame is addressed in wireless communication systems such as frame-based point-to-multipoint wireless communication systems. The described techniques can be used to reduce power consumption at each subscriber station and to elongate the battery time of mobile devices, especially in the bursty Internet data transmission. The subscriber station can use information in the subscriber description segment or activity descriptor to decide whether to turn off receiver power for the remainder of a received downlink frame.

    摘要: A karaoke sound system had a mixer that combines the singer's real-time voice signal from a microphone with the pre-recorded background song/music signal from a player, an amplifier that receives the mixed signal from the mixer to provide amplification or gain boosting, a dedicated channel for the vocal signal from the microphone without using a mixing device, one or more speakers to output the mixed and amplified audio signal, and one or more speakers to output the vocal signal from the dedicated channel. The vocal channel allows the vocals to maintain an overall cleaner and vibrant sound, with a “live feeling” positional presence.

    摘要: A synchronous dynamic RAM capable of segmentally precharging each memory bank. In this SDRAM, each memory bank is divided into multiple memory blocks. Each of these memory blocks internally has its own row access circuitry, but performs independent precharging operation. Access to the memory bank can be cooperative externally, and precharge operation can be separately applied to these memory blocks while allowing utilization of row cache that is available on other blocks. The SDRAM further includes a control device for generating a dedicated precharge signal to each memory block according to a precharge signal for each memory bank. Each dedicated precharge signal independently precharges the corresponding memory block regardless of the access operations executed by other memory blocks. The dedicated precharge signal and a succeeding activate signal for activating a different memory block are overlapped in timing so that the precharge sequence is implanted in the succeeding activate signal and the data access time is shortened.

    摘要: The present disclosure relates to an exhaust treatment article including a substrate having a length that extends along a central longitudinal axis from a first end to second end. The substrate has walls defining a honeycomb arrangement of longitudinal passages that extend along the central longitudinal axis between the first and second ends. The substrate also has first, second and third zones that each extend along a portion of the length of the substrate with the second zone being positioned axially between the first and third zones. The exhaust treatment article also includes a washcoat layer coated on the first and third zones but not coated on the second zone.

    摘要: Wireless communication techniques for cellular deployment of wireless communication systems with transmitters in each cell to have partially overlapped transmission patterns between two adjacent transmitters. Implementations of the described techniques can provide transmit diversity with intentional partial beam pattern overlays to improve cell sectorization or frequency re-use factor, at the same time, reduce intra-cell and inter-cell interference. Various modulations may be used in the described systems, including FDMA, TDMA, and OFDMA modulation schemes.
