System and method for activity monitoring and fall detection
First Claim
1. A personal emergency reporting system (PERS) device comprising:
- an orientation sensor configured to measure orientation of the PERS device;
a transceiver;
processing circuitry configured to;
initiate an orientation measurement based on at least one of timing, manual activation or a sensor detecting an abnormal condition,receive from the orientation sensor an orientation measurement,determine that a predetermined orientation change in a predetermined time has been met,in response to a determination that the predetermined orientation change in the predetermined time has been met, determine whether at least one of;
a fall event has occurred in response to a determination that each of multiple successive changes in orientation between adjacent orientation measurements at least meets a different predetermined threshold, the predetermined thresholds decreasing with increasing change in orientation from an initial orientation, orto enter a more active monitoring state, andin response to a determination that a fall event has occurred, instruct the transceiver to transmit an alert signal to at least one of a local or remote device, the alert signal indicating that a fall event has occurred; and
a housing retaining the sensor, transceiver and processing circuitry and configured to be worn by a user.

Abstract
Devices and methods of using a personal emergency reporting system device is described. The personal emergency reporting system (PERS) device wakes up based on timing, manual activation or an accelerometer in the PERS device detecting an abnormal condition. The PERS device measures the orientation and correlate and sends statistics to a console. The PERS device determines whether a predetermined threshold has been met to determine whether a fall event has occurred or whether to enter a more active monitoring state. The PERS device also determines whether it is appropriate to transmit an alarm to a central monitoring station via the console and transmits the alarm if desired.

12. A method of managing a fall event, the method comprising:
-
measuring orientation of a personal emergency reporting system (PERS) device worn by a user; determining that a fall event has occurred using at least one orientation measurement to determine that a predetermined orientation change has been met, the fall event determined without using an acceleration measurement; in response to determining that a fall event has occurred, transmitting an alert signal indicating that a fall event has occurred to at least one of a local device via a short range communication protocol or a remote device via a network communication protocol; and transmitting orientation history either periodically or at event-driven times in which a periodicity of a transmission of the orientation history is dependent on at least one of previous history, or current time or location of the PERS device. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A personal emergency reporting system (PERS) device comprising:
-
an orientation sensor configured to measure orientation of the PERS device; a transceiver; processing circuitry configured to; initiate an orientation measurement based on at least one of timing, manual activation or a sensor detecting an abnormal condition, receive from the orientation sensor an orientation measurement, determine that a predetermined orientation change in a predetermined time has been met, in response to a determination that the predetermined orientation change in the predetermined time has been met, determine whether at least one of; a fall event has occurred, or to enter a more active monitoring state, in response to a determination that a fall event has occurred, determine whether another PERS device is proximate, and in response to a determination that the other PERS device is not proximate, instruct the transceiver to transmit an alert signal to at least one of a local or remote device, the alert signal indicating that a fall event has occurred, and in response to a determination that the other PERS device is proximate, adjust transmission of the alert signal to avoid transmitting the alert signal or to transmit a modified alert signal; and a housing retaining the sensor, transceiver and processing circuitry and configured to be worn by a user. - View Dependent Claims (20)
