Dual Transceiver Proximity Device Duty Cycling

The patent applies periodic action by implementing duty cycling for the UWB transceiver, where it alternates between active ranging periods and sleep periods. The transceiver performs ranging operations at specific intervals rather than continuously, thereby maintaining measurement precision when needed while significantly reducing average power consumption during extended sleep states.

The patent segments the operation into two distinct transceivers with different functions: a UWB transceiver dedicated to accurate ranging operations and a BLE transceiver for discovery and low-power communication. This segmentation allows each transceiver to be optimized for its specific function, with the BLE transceiver handling discovery to reduce overall system power consumption while the UWB transceiver maintains high precision ranging capability.

The duty cycling mechanism implements periodic action by scheduling UWB ranging operations at specific intervals rather than continuously. The transceiver alternates between active states for ranging and sleep states for power conservation, thereby extending battery life while maintaining the capability for accurate ranging when required by the application.

The patent applies dynamics by making the transceiver operational state variable rather than fixed. The duty cycle can be dynamically adjusted based on application requirements, allowing the system to adapt between more frequent ranging operations (when higher precision is needed) and longer sleep periods (when battery life is prioritized), thus optimizing the balance between measurement precision and duration of action.

The patent segments the transceiver functions into two separate components: a UWB transceiver for high-precision ranging and a BLE transceiver for discovery and low-power communication. This segmentation allows the system to use the high-power UWB transceiver only when needed for accurate ranging, rather than requiring it to operate continuously, thereby reducing the overall power requirements and enabling smaller battery and device design.

The BLE transceiver serves as an intermediary that handles discovery and initial communication, reducing the burden on the high-power UWB transceiver. By using the low-power BLE transceiver for routine discovery operations, the system minimizes the activation time of the high-power UWB transceiver, thereby reducing overall power consumption and enabling more compact device design.
