摘要： An audience polling system includes a plurality of wireless transmitters, each transmitter capable of transmitting a pulse of electromagnetic energy on a selected one of a group of predetermined frequencies. Each frequency selected on which to transmit corresponds to one of a group of suggested responses to a given stimulus. The polling system includes a receiver for receiving the transmitted pulses and electronic counters for tallying the number of pulses received on each of the selected frequencies. An electronic display presents the results of the tallying for observation by the audience or others.

摘要： An electronic voting system includes a plurality of wireless response units, each response unit capable of transmitting several different digitally coded signals. Each of these digitally coded signals corresponds to the response of a person responding to a given stimulus. Each response unit transmits a selected digitally coded response via a radio frequency signal during one of a series of time intervals, a different time interval corresponding to each of the response units. An interrogating and response processing unit signals the response units to commence response transmission and receives, processes and displays the transmitted responses for observation by selected persons.
