    Abstract: Aspects of the present disclosure provide communications between local and remote devices having low-frequency (LF) and high-frequency (HF) circuits. As may be implemented in accordance with one or more embodiments, the local device transmits an LF signal to the remote device, which synchronizes its clock based on the LF signal. Another LF signal is communicated from the local device to the remote device using a reduced quality factor, which can be implemented to facilitate synchronization. The clock is resynchronized based on the second LF signal and used to transmit an HF signal with a time delay. The local device synchronizes its clock based on the HF signal, and transmits another HF signal to the remote device using the clock and another time delay. The remote device re-synchronizes its clock based on the second HF signal while accounting for a trip time for communicating the first and/or second HF signals.

    Abstract translation: 本公开的方面提供具有低频（LF）和高频（HF）电路的本地和远程设备之间的通信。 如可以根据一个或多个实施例来实现的，本地设备向远程设备发送LF信号，该远程设备基于LF信号同步其时钟。 另一个LF信号使用降低的品质因子从本地设备传送到远程设备，这可以被实现以促进同步。 基于第二LF信号重新同步时钟，并用于以时间延迟发送HF信号。 本地设备基于HF信号同步其时钟，并使用时钟和另一个时间延迟将另一个HF信号发送到远程设备。 远程设备基于第二HF信号重新同步其时钟，同时考虑用于传送第一和/或第二HF信号的跳闸时间。

    Abstract: Aspects of the preset disclosure are directed to processing an analog signal transmitted during active portions of a duty cycle. As may be implemented in accordance with one or more embodiments, an apparatus includes a high-speed sampling circuit that samples portions of such an analog signal at a first rate corresponding to the active portion of the duty cycle, and stores the sampled portions of the analog signal. A low-speed analog-to-digital converter accesses the stored sampled portions and converts the sampled portions to a digital form at a second rate that is slower than the first rate.

    Abstract: A passive keyless system including a base that selectively allows access to a restricted environment through a base transceiver operating with an encrypted link on first and second frequencies, and a base recording element storing base measured movement history information. Also, a passive keyless device with at least one sensor detects a movement property of the device, a device recording element stores movement history information about the device and reflecting the detected movement property, and a device transceiver communicating with the base transceiver, and transmitting to the base transceiver encrypted security information identifying the device in accordance with a passive keyless protocol and/or the movement history information, and an access request element that causes the device transceiver to request access to the base transceiver. The base uses the base measured movement history information and movement history information when allowing access to the restricted environment.
