Abstract
Abstract An apparatus to alert a deaf person made up of an alarm device such as a smoke detector adapted to vibrate when actuated by smoke and a transmitter having a vibration sensor connected to the transmitter. The vibration sensor is supported in engagement with the smoke detector and adapted to sense the vibrations of the smoke detector and to transmit a signal to a remotely located receiver. The receiver has a vibrating reed with a tacticle member on its end for engaging a person to alert him when the receiver causes the reed to be vibrated.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
188 words
Apparatus to alert a deaf person of an emergency situation comprising: a vibration sensor for sensing an audible alarm, a radio receiver, a radio transmitter having a vibration pickup adapted to sense the vibration of a smoke alarm, said radio receiver having means to receive transmissions from said transmitter, a tactile stimulator connected to said receiver, said tactile stimulator being adapted to be disposed in engagement with the skin of a person whereby said person is alerted by a transmission from said transmitter to said receiver and to said tactile stimulator when said smoke alarm is operating, said tactile stimulator being a piezoelectric reed connected to a skin engaging member terminating in an end that is substantially a conical member having a point adapted to vibrate at a frequency in the range of 160 HZ, said piezoelectric reed comprises a conductor member sandwiched between two relatively thin non-conductor members supported in fixed position at a first end and having said point member supported on its distal end, and adapted to vibrate in contact with said skin in response to a signal received by said receiver from said transmitter.
Claim 2
Dependent Claim
