摘要： Monitoring a premises may comprise receiving signals from a plurality of devices. One or more spatially static devices of the plurality of devices may be determined based on strengths of the received signals. A user activity pattern may be determined based on changes in strengths of signals received from the spatially static devices. Abnormal user activity may be determined based on the user activity pattern and a strength of at least one signal received from at least one of the spatially static devices.

摘要： A person detection system includes an obtainer and a processing unit. The obtainer obtains a signal strength of a radio wave transmitted by each of a plurality of transmitters and received by an antenna. The processing unit performs a detection process of detecting whether a person is present in a vicinity of the antenna, based on the signal strengths obtained by the obtainer. Each of the plurality of transmitters is classified into any one of a plurality of groups according to a position of the transmitter with respect to the antenna. In the detection process, the processing unit detects that a person is present in the vicinity of the antenna when each of the signal strengths obtained by the obtainer regarding, among the plurality of transmitters, two or more transmitters deviates from a normal range.

摘要： A distance measuring method is applied to measure a distance between a first device and a second device. The first device and the second device include a UWB antenna module. The distance measuring method includes: obtaining the distance between the first device and the second device as an initial distance value; obtaining an actual distance between the first device and the second device according to a first distance measuring mode in response to the initial distance value being in a first distance range; and obtaining the actual distance between the first device and the second device according to a second distance measuring mode in response to the initial distance value being in a second distance range. The second distance measuring mode and the first distance measuring mode are configured to obtain the actual distance between the first device and the second device based on the UWB antenna module.
