Programmable emergency signalling system for a vehicle
First Claim
Patent Images
1. An emergency signalling system for a vehicle comprising:
- a controller for mounting to the vehicle and alternatively operable in programming and operating modes;
a signalling device for broadcasting an emergency warning signal selected by the controller in the operating mode;
a first means of the controller responsive to a user interface and a first memory for (1) placing the controller in the programming mode and (2) selecting the emergency warning signal from a group of available emergency warning signals stored in the first memory, a second memory in communication with the first means for storing the selected emergency warning signal;
second means of the controller in communication with the second memory and responsive to the user interface when the controller is in the operating mode for delivering the selected emergency warning signal to the signalling device; and
, the controller including a control head in serial communication with a control unit, where the control head is responsive to the user interface and the control unit controls the signalling device.

Abstract
A signalling system is provided that is alternatively operable in programming and operating modes. The signalling system includes a keypad, control head, control unit and a plurality of signalling features selectively activated by the control unit in the operating mode. The system provides for keystrokes to the keypad placing the system in the programming mode and selecting the signalling features to be activated by the control unit in the operating mode.

7. A method of using an emergency signalling system installed in a vehicle, the system including (1) a programmable controller alternatively operable in programming and operating modes and (2) at least two signalling configurations of warning signals, the method comprising the steps of:
-
switching the programmable controller to the programming mode; entering commands at a user interface that enables at least one of the signalling configurations of warning signals for activation in the operating mode of the programmable controller; switching the programmable controller to the operating mode; selecting one of the enabled signalling configurations of warning signals when the system is installed in the vehicle; and activating the selected signalling configuration of warning signals in order to generate an emergency signal in an ambient environment of the vehicle. - View Dependent Claims (8, 9, 10, 11, 12)

13. For incorporation into a vehicle, an emergency signalling system comprising:
- a control head for mounting in a passenger compartment of the vehicle and including a user interface;
a control unit and power amplifier for mounting in an interior area of the vehicle at a location that is remote from the control head;
each of the control head and control unit including at least one port for serial communication;
a bi-directional communication bus connecting the serial ports of the control head and the control unit;
a signalling device responsive to the control unit and power amplifier; and
means in the control unit responsive to a user input at the control head for activating the signalling device in order to generate an emergency warning signal. - View Dependent Claims (14)
