Wearing compliance of personal emergency response system help button
First Claim
1. A device for use in conjunction with a personal emergency response system (PERS), the device comprising:
- a wearable personal help button including a call button, a motion sensor, and a transmitter or transceiver configured to transmit a wireless call signal in response to the call button being pressed; and
an electronic processor programmed to perform a compliance monitoring process using the motion sensor to assess compliance with wearing the wearable personal help button wherein the compliance monitoring process is performed at successive compliance check times and includes, at each compliance check time;
acquiring motion sensor data from the motion sensor of the wearable personal help button over a compliance data acquisition time interval shorter than the time interval between successive compliance check times;
determining from the motion sensor data acquired over the compliance data acquisition time interval whether the wearable personal help button has moved since the last compliance check time by;
determining a current orientation (vDir) of the wearable personal help button from the motion sensor data acquired over the compliance data acquisition time interval; and
determining the wearable personal help button has moved since the last compliance check time if a difference (Δ
vDir) between the current orientation of the wearable personal help button and the orientation of the wearable personal help button determined for the last compliance check time exceeds a threshold difference (Δ
th); and
assessing compliance with wearing the wearable personal help button based at least in part on the determination of whether the wearable personal help button has moved since the last compliance check time.

Abstract
In a personal emergency response system (PERS), a personal help button (PHB) (10) includes a call button (12), a motion sensor (22), and a transmitter or transceiver (24) for transmitting a wireless call signal responsive to pressing the call button. An electronic processor (28) performs a compliance monitoring process (42) at successive compliance check times, each including: acquiring motion sensor data over a compliance data acquisition time interval; determining whether the PHB has moved since the last compliance check time; and assessing compliance based at least in part on the determination of whether the PHB has moved. The determining may include determining an orientation change of the PHB since the last check time. Alternatively, compliance may be monitored by detecting and logging wake-up interrupt events that cause the motion sensor to switch from a low-power mode to an operational mode.
