Abstract: An alarm for sending out distress information when the user is in an abnormal position or when the user wishes to alert others of a distress condition. The alarm includes an omni-directional tilt switch and a transmitter. When the tilt switch has passed a critical angle, a signal is sent to a delay circuit. The delay circuit waits for a predetermined period of time, such as ten seconds, before enabling a transmitter. The transmitter then sends information over a communication link, signaling others that the user is in need of assistance. The invention further includes an alarm for alerting the user that the predetermined position of the tilt switch has been satisfied and that, after the predetermined delay, the distress information will be transmitted over the communication link unless deactivated by the user.
