    摘要： A time-framed communications transceiver maintains synchronization through fade conditions by resetting a counter (640) whenever new synchronization parameters are stored in a memory (630) based on bursts detected by a receiver (610) and a burst synchronizer (620). A transmitter (690) transmits bursts based upon the synchronization parameters in the memory (630) when the time counter (640) has not exceeded a predetermined period of time. The receiver (610) re-establishes the synchronization parameters in the memory (630) when the time counter exceeds another, longer predetermined period of time before transmission by the transmitter (690).

    摘要翻译： 基于由接收机（610）和突发同步器（620）检测到的突发，每当新的同步参数存储在存储器（630）中时，通过复位计数器（640），时间帧通信收发器通过淡入淡出来维持同步。 当时间计数器（640）尚未超过预定时间段时，发送器（690）基于同步参数在存储器（630）中发送脉冲串。 当时间计数器超过由发射机（690）发射之前的另一较长的预定时间段时，接收器（610）重新建立存储器（630）中的同步参数。

    摘要： An acrylic acid ester polymer having improved characteristics and oleaginous compositions containing the acrylic acid ester polymer. The acrylic acid ester polymer includes a copolymer derived from a first acrylic acid ester monomer having from about 1 to about 4 carbon atoms, a second acrylic acid ester monomer having from about 12 to about 14 carbon atoms, and a third acrylic acid ester monomer having from about 16 to about 20 carbon atoms. The copolymer has a weight average molecular weight ranging from about 20,000 to about 100,000 daltons and contains no more than about 1 weight percent unreacted monomer.
