Abstract
A cellular phone based emergency vessel/vehicle location system which includes a navigation unit to determine position and speech synthesis to modulate a transmitter with the emergency message includes a combined dialer and activation detector, in which activation may either be from the cellular phone keypad or from a panic button, a Lojack/hijack sensor, a car theft alarm, airbag deployment, a man down sensor, or other form of remote activation. Upon activation, the activation detector/dialer causes DTMF tones to be generated for telephone number dialing. After dialing, the transmitter for the transceiver is modulated with the emergency message in natural speech. In one embodiment, the dialer and activation detector is actuated from the keypad of the cellular phone, such as 911, *CG, *SP or other predetermined activation code. As a further feature, the number to be dialed is entered into the dialer prior to using the device, or optionally, the number to be dialed can be transmitted to the cellular phone and thence to the dialer when, for instance, a cellular phone is within range of a given cell site.
