Abstract
Home safety and security are provided using a bedside unit to monitor an audible personal security pendant and to send notification signals to the appropriate communication site. Improved reliability is achieved by comparing a stored signal signature to the real time digital pattern representing sounds received using digital acoustic signature recognition technology.
Claims8
A method for monitoring an area for an audible signal generated by a personal alert pendant activated by an individual in an emergency situation, the method comprising:
- operating a sound monitoring unit including a microphone, a memory having a signal signature of the personal alert pendant stored therein, a microprocessor and a communications port;
- and
- by operating the unit, detecting sounds received by the microphone of the unit and converting the sounds to a real time digital pattern representing the sounds;
- using the microprocessor and a digital acoustic signature recognition technology, comparing the real time digital pattern to the signal signature stored in the memory and determining if detected sound represents a signal from the personal alert pendant, wherein the digital acoustic signature recognition technology comprises a technique selected from the group consisting of matched filtering, cross correlation, and neural networking;
- and in response thereto generating and sending response signals out the communications port of the monitoring unit.
