    • An integrated circuit is presented in which optical signal propagation replaces or supplements conventional electrical signal propagation. Optical lasers, waveguides, beam splitters, and photodetectors are fabricated on top of or below conventional electrical semiconductor circuits to propagate data, clock, and control signals. Such optical signal propagation is generally more rapid than electrical signal propagation, and can free conventional electrical semiconductor circuit area by eliminating at least some conventional data busses and global clock and control wiring. Furthermore, optical clock signal propagation substantially eliminates clock skewing problems and reduces power consumption by significantly eliminating clock signal re-buffering.
    • 提出了一种集成电路,其中光信号传播取代或补充传统的电信号传播。 光学激光器,波导,分束器和光电检测器制造在常规电半导体电路之上或之下,以传播数据,时钟和控制信号。 这种光信号传播通常比电信号传播更快,并且可以通过消除至少一些常规的数据总线和全局时钟和控制布线来释放常规的电半导体电路区域。 此外,光时钟信号传播基本上消除了时钟偏移问题,并通过显着消除时钟信号重新缓冲来降低功耗。

    • A communication system (10) has at least one communication resource controller (28) for allocating a limited number of communication resources among a plurality of communication units. The communication resource controller monitors the communication resources and maintains a data library of the level and duration of any interference of the communication resources. The communication units (20 and 22) are constructed and arranged to communicate information on any of the communication resources. Any one of the plurality of communication units can initiate access to a communication resource by transmitting a request therefor. In response to a proper request, the communication resource controller (28) assigns a communication resource the communication units in accordance with the data retrieved from the interference data library.

    • A radio transceiver includes a read only memory (ROM) for storing an origination code and a random access memory (RAM) for storing a destination code. The destination code may be manually entered into the RAM via a keypad or it may be entered remotely from another transceiver. In signalling between two transceivers, the destination code is transmitted followed by the origination code indicating the transmission's origin. In this manner coded squelch communications may take place between two parties without the necessity of reverting to carrier squelch operation while obtaining enhanced user privacy and flexibility.
    • 无线电收发机包括用于存储起始码的只读存储器(ROM)和用于存储目的地代码的随机存取存储器(RAM)。 目的地代码可以通过键盘手动输入到RAM中,或者可以从另一收发器远程输入。 在两个收发器之间的信令中,发送目的地码,随后发送指示传输原点的发起码。 以这种方式,编码的静噪通信可以在两方之间进行,而不需要恢复到载波静噪操作,同时获得增强的用户隐私和灵活性。

    • A radio frequency transceiver is provided in which the crystal resonator and monolithic crystal filter devices therein all operate at or near the operating frequency of the transceiver, and which employs a single piezoelectric element to achieve the functions of receiver signal filtering, transmitter signal filtering, receiver local oscillator signal generation, and transmitter local oscillator signal generation. To achieve these functions, a crystal resonator and a monolithic crystal filter are situated on the same substrate of piezoelectric material. The crystal resonator portion of the piezoelectric device is employed to control the frequency at which a local oscillator generates radio frequency energy. Such crystal controlled local oscillator is shared by a receiver mixer circuit and a transmitter mixer circuit. Switching circuitry is employed to switch the crystal filter portion of the piezoelectric device from the receiver signal path to the transmitter signal path.
