US 12,004,054 B1 · Electronic devices with motion-based proximity sensing

Abstract

A system may have electronic devices with wireless communications circuitry. Devices may transmit short-range wireless signals such as advertising packets. Each advertising packet may contain information on the motion context of the transmitting device. By comparing motion context information for received packets with local motion context information, an electronic device may analyze received signal strength indicator measurements with enhanced accuracy. Presence-in-vehicle state information and/or other device context may also be obtained from nearby devices by comparing local and received motion context.

Dependent claims

An electronic device, comprising:

a sensor;
a short-range radio-frequency transceiver configured to receive advertisement packets from a remote device, wherein the advertisement packets include remote device motion context;
and
control circuitry configured to:
measure local motion context with the sensor;
and
measure received signal strength indicator values associated with the received advertisement packets;
compare the remote motion context and the local motion context;
and
ignore erroneous received signal strength indicator values from among the measured signal strength indicator values based on the comparison of the remote motion context and the local motion context.
