Control head with electroluminescent panel in land mobile radio

摘要

An exemplary land mobile radio control head and method are provided. In one embodiment, the control head has the capability to utilize halo light of the control head to implement a multi-function indicator that communicates a state of the land mobile radio. In another embodiment, the control head has the capability to provide buffer images constructed from data received from the land mobile radio into a video stream for rendering on an electroluminescent display. In another embodiment, the control head provides the capability for a user to modify a configuration stored on the land mobile radio that defines one of several display modes to be utilized in generating data for use in forming images to be rendered on an electroluminescent display.

主权项

1. A control head for use with a land mobile radio, the control head comprising:
a plurality of user interface input/output components, one or more first light pipes each having a first LED operable to illuminate a respective one of the one or more first light pipes to provide a halo light for at least one of said user interface input/output components; a second light pipe having a plurality of indicator LEDs each operable to illuminate the second light pipe to provide an indicator halo light for at least another one of said user interface input/output components; and a control system configured to determine a state of the land mobile radio, to control activation of the first LEDs, and to control individual activation of the indicator LEDs, wherein the control system is operable, in response to determining the state of the land mobile radio, to control activation of each of the indicator LEDs to indicate the state of the land mobile radio via the indicator halo light, wherein the control system is operable to monitor the state of the land mobile radio and, in response to detecting a change in the state of the land mobile radio, to control activation of each of the indicator LEDs to indicate the change in the state of the land mobile radio via the indicator halo light, wherein the control system is operable to activate a first one of the plurality of indicator LEDs to illuminate the second light pipe and the indicator halo light a first hue to indicate the land mobile radio is in an idle state, wherein the control system is operable to activate a second one of the plurality of indicator LEDs to illuminate the second light pipe and the indicator halo light a second hue to indicate the land mobile radio is in a transmit state, and wherein the control system is operable to activate a third one of the plurality of indicator LEDs to illuminate the second light pipe and the indicator halo light a third hue to indicate the land mobile radio is in a receive state.
