Abstract
Abstract A multiple remote control VCR pause switch is provided which allows any number of viewers to pause an accessory video cassette recorder to, for example, answer questions posed on the video tape. Each viewer is provided with a response switch mounted inside a cabinet. A valid first response lamp and an invalid response lamp are provided on a switch console for each response switch. The first viewer to activate his response switch pauses the VCR and causes his valid first response lamp to illuminate. Subsequent activation of any of the remaining response switches has no effect and the invalid response lamps for those response switches stay illuminated. A reset switch is provided and the rewind search may be remotely controlled.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
217 words
Multiple remote control VCR pause switch, comprising in combination: (a) N momentary contact response switches, each mounted in an individual cabinet, connected to a switching console, wherein said switching console controls the pause and the rewind functions of an accessory video cassette recorder such that when any of said momentary contact response switches is activated said video cassette recorder pauses; (b) N valid first response lamps, one for each said response switch, such that when the first of said response switches is depressed its respective said valid first response lamp is illuminated; however, any subsequent activation of any of remaining said response switches does not result in the illumination of any remaining said valid first response lamps; (c) N invalid response lamps, one for each said response switch, such that said invalid response lamps are all normally illuminated until the said first activation of said response switch wherein said respective invalid response lamp is extinguished and all remaining said invalid response lamps remain illuminated; (d) a momentary contact reset switch which, when activated, causes said accessory video cassette recorder to resume its normal playback feature and also causes all said invalid response lamps to return to their normally illuminated condition; and, (e) a rewind-search switch which remotely activates the rewind-search function of said accessory video cassette recorder.
Claim 2
Dependent Claim
217 words
Multiple remote control VCR pause switch, comprising in combination: (a) N momentary contact response switches, each mounted in an individual cabinet, connected to a switching console, wherein said switching console controls the pause and the rewind functions of an accessory video cassette recorder such that when any of said momentary contact response switches is activated said video cassette recorder pauses; (b) N valid first response lamps, one for each said response switch, such that when the first of said response switches is depressed its respective said valid first response lamp is illuminated; however, any subsequent activation of any of remaining said response switches does not result in the illumination of any remaining said valid first response lamps; (c) N invalid response lamps, one for each said response switch, such that said invalid response lamps are all normally illuminated until the said first activation of said response switch wherein said respective invalid response lamp is extinguished and all remaining said invalid response lamps remain illuminated; (d) a momentary contact reset switch which, when activated, causes said accessory video cassette recorder to resume its normal playback feature and also causes all said invalid response lamps to return to their normally illuminated condition; and, (e) a rewind-search switch which remotely activates the rewind-search function of said accessory video cassette recorder.
Claim 3
Dependent Claim
137 words
A multiple remote control VCR pause switch, as recited in claim 1, wherein said switching console further comprises an (N+1) pole relay and N latching relays connected such that the activation of any of said response switches causes its respective said latching relay to latch; thereby activating said (N+1) pole relay to prevent any of the remaining said latching relays from activating; each of said valid first response lamps is connected in parallel with the coil of each of said respective latching relays whereby only one valid first response lamp is ever illuminated; and each of said invalid response lamps is connected to a normally-closed set of contacts on each of said respective latching relays whereby each of said invalid response lamps is illuminated except when a first activation of any of said response switch has occurred.
Claim 4
Dependent Claim
32 words
A multiple remote control VCR pause switch, as recited in claim 1, wherein said momentary contact reset switch interrupts power to all of said latching relays whereby said latching relays are un-latched.
