Abstract: A secure ranging system can use a secure processing system to deliver one or more ranging keys to a ranging radio on a device, and the ranging radio can derive locally at the system ranging codes based on the ranging keys. A deterministic random number generator can derive the ranging codes using the ranging key and one or more session parameters, and each device (e.g. a cellular telephone and another device) can independently derive the ranging codes and derive them contemporaneously with their use in ranging operations.

Abstract: Embodiments of an apparatus and method are disclosed that may allow for managing power of a computing system. The apparatus may include a clock generation circuit, a bus interface unit, and a control circuit. The clock generation circuit may be configured to generate multiple clock signals. Each clock signal may provide a timing reference to different functional blocks within a device coupled to the communication bus. The bus interface unit may be configured to receive messages from the device via the communication bus. The messages may include a latency value and a request to activate a low power mode. The control circuit may be configured to deactivate one or more of the multiple clock signals dependent upon the latency value and multiple threshold values.
