    Abstract: Various operations may be performed based on a distance-related function associated with two or more devices. For example, an association procedure for two or more devices may be based on one or more determined distances. Similarly, presence management may be based on one or more determined distances. A distance-related function may take various form including, for example, a distance between devices, two or more distances between devices, a rate of change in a relative distance between devices, relative acceleration between devices, or some combination of two or more of the these distance-related functions.

    Abstract: An apparatus, which may be configured as a receiver or transceiver, includes a plurality of super regenerative (SR) amplifiers coupled in parallel, wherein the SR amplifiers are tuned to distinct frequency bands, respectively. The apparatus may further include isolation amplifiers at the respective inputs and outputs of the SR amplifiers to prevent injection locking and reduce power leakage. The apparatus may include a circuit to reduce or substantially eliminate in-band jamming signals. The apparatus may form at least part of a wireless communications device adapted to receive signals from other wireless communications devices, adapted to transmit signal to other wireless communications devices, and adapted to both transmit and receive signals to and from other wireless communications devices.

    Abstract translation: 可以被配置为接收器或收发器的设备包括并联耦合的多个超再生（SR）放大器，其中SR放大器分别被调谐到不同的频带。 该设备可以进一步包括在SR放大器的相应输入和输出处的隔离放大器，以防止注入锁定并减少功率泄漏。 该装置可以包括用于减少或基本上消除带内干扰信号的电路。 该设备可以形成无线通信设备的至少一部分，该无线通信设备适于从其他无线通信设备接收信号，适合于向其他无线通信设备发送信号，并适用于向其他无线通信设备发送信号以及从其他无线通信设备接收信号。
