Abstract
An audience response system includes a console having a plurality of pairs of lamps in which one lamp of each pair is grouped with corresponding ones of the lamps of the other pairs. The system also includes a plurality of switches, each for controlling the lighting of a different pair of lamps, and a plurality of timers, each of which is activated by a different one of the switches. When a particular one of the lamps of a pair is lighted by the associated switch, then the corresponding timer is also activated, and when the other lamp of the pair is lighted, the corresponding timer is deactivated. An additional switch is provided to activate an additional timer and deactivate the plurality of timers.
Claims7
An audience response system comprising
- first and second groups of visual indicators, each indicator in one group being paired with an indicator in the other group,
- a plurality of switches, each for distribution to and use by a different member of an audience and each corresponding to a different pair of said indicators and having first and second positions, said switches each being manually operable to activate one indicator of a corresponding pair while in the first position and to activate the other indicator of the pair while in the second position,
- a plurality of timers, each coupled to a different one of said switches for activation while the corresponding switch is in the first position to thereby indicate the duration that the corresponding switch is in the first position,
- an additional timer, and
- an additional switch coupled to said additional timer and said plurality of timers for deactivating the plurality of timers and activating the additional timer when the additional switch is in a first position, and for deactivating the additional timer when the additional switch is in a second position.
An audience response system comprising
- a plurality of pairs of visual indicators, a first indicator of each pair grouped with the other indicators and a second indicator of each pair grouped with the other second indicators, said first group of indicators being spatially separated from said second group of indicators
- a plurality of manually operable two-position switches for distribution to and use by members of an audience, each switch coupled to a different pair of indicators for selectively activating the first indicator of the pair when the switch is operated to a first position and for activating the second indicator of the pair when the switch is operated to a second position,
- means for providing, at any given time, an indication of the proportion of said plurality of switches which are at that time activating the corresponding said particular indicators,
- a selection switch coupling said indication providing means to selected ones of said plurality of switches, and
- means for biasing said indication providing means to indicate the proportion of switches, of those coupled to the indication providing means, which are activating the corresponding said particular indicators.
