Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
254 words
An automobile display control system in combination with an on-board display for displaying visual information on a screen and arranged in a vehicle, said control system operating for controlling said display, comprising: selector means for manually selecting an operating mode of interest to a user from among a plurality of operating modes, said display displaying different visual information at different operating modes, said selector means generating a selected operating mode indicative signal identifying a selected operating mode selected thereby; display control means responsive to said selected operating mode indicative signal, for controlling said display to display particular visual information on said screen at the selected operating mode; manually operated blanking switch means operating in a blanking state for blanking the particular visual information displayed on said screen in the selected operating mode and for generating a blanking signal when operating in said blanking state; said control means being responsive to said blanking signal for controlling said display to blank the visual information displayed on said screen; and a touch switch panel disposed over said display for defining an entire switching area over an entire surface of said screen for sensing user contact with any portion of said entire switching area and for generating a user-contact indicative signal; wherein said control means is responsive to said user-contact indicative signal in the presence of said blanking signal for shifting a state of said blanking switch means from said blanking state to a non-blanking state for re-displaying the visual information previously blanked by said blanking switch means.
Claim 2
Dependent Claim
254 words
An automobile display control system in combination with an on-board display for displaying visual information on a screen and arranged in a vehicle, said control system operating for controlling said display, comprising: selector means for manually selecting an operating mode of interest to a user from among a plurality of operating modes, said display displaying different visual information at different operating modes, said selector means generating a selected operating mode indicative signal identifying a selected operating mode selected thereby; display control means responsive to said selected operating mode indicative signal, for controlling said display to display particular visual information on said screen at the selected operating mode; manually operated blanking switch means operating in a blanking state for blanking the particular visual information displayed on said screen in the selected operating mode and for generating a blanking signal when operating in said blanking state; said control means being responsive to said blanking signal for controlling said display to blank the visual information displayed on said screen; and a touch switch panel disposed over said display for defining an entire switching area over an entire surface of said screen for sensing user contact with any portion of said entire switching area and for generating a user-contact indicative signal; wherein said control means is responsive to said user-contact indicative signal in the presence of said blanking signal for shifting a state of said blanking switch means from said blanking state to a non-blanking state for re-displaying the visual information previously blanked by said blanking switch means.
Claim 3
Dependent Claim
108 words
The display control system as set forth in claim 1, further comprising run detecting means for detecting a running state of the vehicle and for generating a vehicle-running indicative signal, wherein said selector means includes means for selecting a television display mode for displaying a television broadcast image, and said blanking switch means comprises means responsive to said vehicle-running indicative signal for outputting to said control means a further blanking signal responsive to said vehicle-running indicative signal, said control means being responsive to said further blanking signal for controlling said display to blank the television broadcast image displayed on said screen when said television display mode is selected.
Claim 4
Dependent Claim
64 words
The display control system as set forth in claim 2, wherein said touch switch panel includes a plurality of pairs of corresponding light emitting and light receiving diodes diametrically opposed to each other around said screen, wherein a light receiving diode provides said user-contact indicative signal to said control means when a user's finger interrupts light transmission from a light emitting diode corresponding thereto.
Claim 5
Dependent Claim
81 words
The display control system as set forth in claim 3, wherein said selector means includes a plurality of user contact areas, each smaller than said touch switch panel, for generating a plurality of separate signals identifying user contacts with separate ones of said user contact areas, and wherein, in the presence of said blanking signal, said control means is responsive to said user-contact indicative signal for re-displaying the visual information in said selected operating mode previously selected by said selector means.
Claim 6
Dependent Claim
47 words
The display control system as set forth in claim 2, wherein when said control means responds to said further blanking signal by blanking only the television broadcast image displayed on said screen, while maintaining an output of an audio sound portion superposed on the television broadcast image.
Claim 7
Dependent Claim
81 words
The display control system as set forth in claim 5, wherein said selector means includes a plurality of user contact areas, each smaller than said touch switch panel, for generating a plurality of separate signals identifying user contacts with separate ones of said user contact areas, and wherein, in the presence of said blanking signal, said control means is responsive to said user-contact indicative signal for re-displaying the visual information in said selected operating mode previously selected by said selector means.
Claim 8
Dependent Claim
81 words
The display control system as set forth in claim 4, wherein said selector means includes a plurality of user contact areas, each smaller than said touch switch panel, for generating a plurality of separate signals identifying user contacts with separate ones of said user contact areas, and wherein, in the presence of said blanking signal, said control means is responsive to said user-contact indicative signal for re-displaying the visual information in said selected operating mode previously selected by said selector means.
Claim 9
Dependent Claim
81 words
The display control system as set forth in claim 1, wherein said selector means includes a plurality of user contact areas, each smaller than said touch switch panel, for generating a plurality of separate signals identifying user contacts with separate ones of said user contact areas, and wherein, in the presence of said blanking signal, said control means is responsive to said user-contact indicative signal for re-displaying the visual information in said selected operating mode previously selected by said selector means.
