摘要： Low power wireless communication techniques may be employed in devices that communicate via a wireless body area network, a wireless personal area network, or some other type of wireless communication link. In some implementations the devices may communicate via one or more impulse-based ultra-wideband channels. Inter-pulse duty cycling may be employed to reduce the power consumption of a device. Power may be provided for the transmissions and receptions of pulses by charging and discharging a capacitive element according to the inter-pulse duty cycling. Sub-packet data may be transmitted and received via a common frequency band. A cell phone may multicast to two or more peripherals via wireless communication links.

摘要： Various techniques are described relating to verifying a distance between devices. A distance between two devices may be verified by requiring one of the devices to take one or more actions that generate a result that is only possible if the device is at most a given distance from the other device. In some aspects verified ranging is accomplished through the use of a ranging signal and a responsive signal. In some aspects the ranging signal may comprise a random, pseudorandom, or deterministic sequence. A responding device may operate on a ranging signal in accordance with a known function to generate a responsive signal. A ranging device also may perform operations to determine the likelihood that a responding device properly operated on a ranging signal that the ranging device transmitted to the responding device.

摘要： Phase of an output signal is based on comparison of an oscillating signal with an adjustable threshold. Here, adjustment of the threshold results in a corresponding adjustment of the phase of the output signal. For example, the adjustable threshold may comprise an adjustable bias signal for a transistor circuit whereby the oscillating signal is provided as an input to the transistor circuit and the output of the transistor circuit provides the output signal. In some aspects these phase adjustment techniques may be employed to provide one or more tunable multiphase clocks.

摘要： A tunable delay line is calibrated to maintain the delay of the delay line at a desired value or within a desired range of values. In some aspects a signal is passed through a delay line multiple times so that the cumulative delay of the signal through the delay line (e.g., as indicated by a count) may be calculated over a period of time. The count is compared with an expected count and, based on this comparison, the delay of the delay line is adjusted as necessary. In some aspects the signal may comprise a digital signal. In some aspects a delay through a delay line may be calculated based on analysis of amplitude changes in a signal caused by a phase shift imparted on the signal by the delay line. In some aspects a delay line is incorporated into a transmitted reference system to generate and/or process transmitted reference signals.
摘要翻译：校准可调延迟线以将延迟线的延迟保持在期望值或期望的值范围内。在一些方面，信号通过延迟线多次，使得通过延迟线的信号的累积延迟（例如，由计数指示）可以在一段时间内被计算。将计数与期望计数进行比较，并根据该比较，根据需要调整延迟线的延迟。在一些方面，信号可以包括数字信号。在一些方面，通过延迟线的延迟可以基于由由延迟线对信号施加的相移引起的信号中的幅度变化的分析来计算。在一些方面，将延迟线并入到传输的参考系中以产生和/或处理传输的参考信号。
