US 2026/0276807 A1 · MONITORING AN ENVIRONMENT TO CONTROL AN ACTIVE REFLECTED WAVE DETECTOR

Abstract

An environment is monitored to control an active reflected wave detector. It is determined, based on an output from a different device to the active reflected wave detector, whether a person is at an away location that is outside a region of interest during a time period that is after a detected triggering event. In response to a predefined criterion being met, the active reflected wave detector is switched from a first state to operate in a second state in which the active reflected wave detector measures wave reflections from a region of interest. The active reflected wave detector consumes more power in the second state than in the first state. The predefined criterion comprises that the time period has expired. If a condition comprising that a person is at an away location during the time period is satisfied, it is concluded that the predefined criterion is not met.

Dependent claims

A computer implemented method of monitoring an environment to control an active reflected wave detector installed in a premises, wherein the active reflected wave detector is part of a system comprising at least one different device to the active reflected wave detector that is also installed in the premises, the method comprising:

detecting a triggering event;
determining, based on an output from at least one different device to the active reflected wave detector, whether a person is detected as being at an away location in the premises that is outside a region of interest of the active reflected wave detector during a time period that is after the triggering event;
in response to a predefined criterion being met, switching the active reflected wave detector from a first state to operate in a second state in which the active reflected wave detector measures wave reflections from the region of interest within the environment, wherein the active reflected wave detector consumes more power in the second state than in the first state, the predefined criterion comprising that the time period has expired;
and
in response to satisfaction of a condition comprising that a person is detected as being at an away location during the time period, concluding that the predefined criterion is not met.
