Abstract: Techniques for a dynamic radar mode modulation feature are described herein. A computer system associated with a device may implement a first radar configuration for a radar sensor. The first radar configuration may correspond to a first mode and comprise a first frame per second rate and a first difference threshold. The computer system may receive first data from the radar sensor in the first radar configuration. The computer system may determine a presence of an object within a field of view of the radar sensor based on the first data and the first difference threshold. The computer system may instruct the device to turn on based on determining the presence of the user. The radar sensor may be instructed to implement a second radar configuration associated with a second mode.

Abstract: Technologies directed to data transfer protocols for Ultra-Wideband (UWB) are described. One method includes a UWB radio of a first device receiving first data from an application. The first device sends data to second and third devices, the data identifying a number of data rounds, a duration of each round, a duration of a data slot, a duration of a data block, and a first slot index for the second device and a second slot index for the third device. The first device sends, during a first slot associated with the first slot index, the first data to the second device using the UWB radio. The first device sends, during a second slot associated with the second slot index, the first data to the third device using the UWB radio.
