Abstract

A vehicle message terminal comprising a car radio receiver incorporating separate receiving circuits for paging messages and public entertainment broadcasts. The receiver has a common antenna input 11 for both circuits and a front panel 12 incorporating conventional radio tuning scales 13 and light emitting diode visual display 14 for paging messages. The paging receiver is powered from the vehicle battery via the ignition switch. <IMAGE>

Description

SPECIFICATION Vehicle message terminal This invention relates to vehicle message terminals for, e.g. conveying urgent messages to motorists.
The development of modern radio paging systems with small pocket-sized receivers is progressing beyond the simple "bleep" only type of receiver. There are currently radiopaging systems which will provide voice communication via the receiver or messages for visual display in the receiver. However such paging receivers are at a disadvantage when used by motorists for several reasons. Firstly, inside a vehicle they are subject to considerable electromagnetic screening by the vehicle body. Audio alert tones may be marked by the noise of the vehicle and adjacent road traffic noise. For visual displays it is difficult to place a small pocket receiver in a suitable position in a vehicle where a driver can readily read the display, bearing in mind that the display is usually a small liquid crystal device (LCD) which requires external illumination to render it visible.Of course a display can be a light emitting diode (LED) display to achieve brightness but it is still a small display to read and has a comparatively high power consumption.
According to the present invention there is provided a vehicle message terminal comprising a car radio receiver incorporating separate receiving circuits for both public entertainment broadcast signals and special paging message signals, the receiver having a front panel in which is mounted a light emitting diode (LED) alphanumeric display panel wherein messages received for the vehicle user are displayed.
An embodiment of the invention is now described with reference to the accompanying drawing illustrating a vehicle message terminal.
The terminal is contained within a housing 10 which is fitted with two printed circuit boards (not shown), one for the conventional car radio circuitry and one for the message terminal circuitry. Both printed circuits receive their r.f. inputs from a common antenna input 11. The front panel 1 2 incorporates the conventional radio volume and tuning controls and tuning scale 13, together with a visual alphanumeric display 1 4 for paging messages. The alphanumeric display is implemented with light emitting diodes to provide a bright large character display visible both in daylight and at night and readily readable from a distance of up to 1 metre. The complete unit may thus be mounted in a conventional position for a car radio, e.g. in a central console, allowing the driver to read messages without difficulty whilst driving.Because the visual LED display can be powered from the car battery the power requirements of the diodes are not a limiting factor in the design.
The paging receiver may be powered separately from the car radio, allowing it to be operative even when the radio is not in use.
For example, the paging circuity may be automatically switched on by operation of the car ignition switch so that it is always in operation when the car is in use. Pager controls, such as the reset button for the display, can be mounted either on the front panel or at some other position suitable for operation by the driver and connected to the unit by an electric cable. For paging systems with voice communication the audio output can be fed into the normal car radio audio output amplifier and loudspeaker. The circuitry can also include an entertainment broadcast muting circuit responsive to a paging voice communication whereby the paging message can override the normal entertainment broadcast output.
1. A vehicle message terminal comprising a car radio receiver incorporating separate receiving circuits for both public entertainment broadcast signals and special paging message signals, the receiver having a front panel in which is mounted a light emitting diode (LED) alphanumeric display panel wherein messages received for the vehicle user are displayed.
2. A terminal according to claim 1 wherein the paging signals receiving circuit and the entertainment broadcast receiving circuit receive r.f. inputs from a common antenna.
3. A terminal according to claim 1 or 2 wherein the paging signals receiving circuit is powered from the vehicle battery under the control of the vehicle ignition switch.
4. A terminal according to any preceding claim including an entertainment broadcast muting circuit responsive to paging voice communication whereby paging messages override the entertainment broadcast output.
5. A vehicle message terminal substantially as described with reference to the accompanying drawing.
