The present invention provides a protective garment with impact detection and alarm notification capability. The monitoring garment, while offering protection from fall related injuries allows for automatically detecting falls, with great reliability by employing a fall v. daily activity recognition algorithm. As a result, false alarms are discarded while the real event triggers the alarm.
The protective & monitoring garment is preferably constructed as a hip or a shoulder protector with the aim at shielding parts of the wearer’s body which are most commonly affected in case of a fall, which are the trochanter bone and the shoulder bone. The garment is truly wearable, easy to put on and undo, and houses the wireless monitoring device in an unobtrusive way.
The monitoring device may acquire data from an analog or digital accelerometer, which can sense changes in acceleration of the user in two or three dimensions X, Y and Z. The monitoring device may incorporate a microprocessor, a flash memory with pre stored software program suite, a wireless transmitter and a power source. In case of a serious fall, an alarm notification is generated and transmitted.
The alarm message may be sent by wireless GSM/GPRS mobile phone technology to a remote receiver, which may be a mobile phone or PDA. This feature caters for situations when the user is located in open spaces, or living at home.
The alarm message may be sent wirelessly to a Central Monitoring Station, such as a nursing station. This feature caters for situations when the wearer resides in a nursing home or a hospital.
The protective & monitoring garment may also monitor basic vital signs such as temperature and heart beat by analysing data acquired from additional ^nsorT mco^oraled info'the garment, in order to assess the user’s state of emergency *............
