Portable alerting device for use in cell phone for alerting fall and/or discomfort of e.g. elder person, has transmitter/receiver sending warning message to monitoring device when acceleration value exceeds threshold limit value

摘要

The device has an accelerometer (3) for measuring an acceleration value such as an angular velocity of the portable device, and a comparator (4) for comparing the acceleration value measured by the accelerometer with a threshold limit value determined in advance. An initiating unit initiates a transmitter/receiver (2) such that the transmitter/receiver sends a warning message to a monitoring device or a monitoring center when the acceleration value exceeds the predetermined threshold limit value. An independent claim is also included for a method for providing a remote alert upon detection of a fall and/or discomfort of a carrier of a monitoring device.
