First Claim
1. An audience response system comprising:
- a base unita plurality of handheld devices that are like in kind and perform a same function, each handheld device including;
a handheld device transceiver,an input selection control,a unique address associated with a single handheld device, andhandheld device logic configured to receive a user selection from the input selection control and instruct the handheld device transceiver to transmit a wireless selection signal encoding the unique address and the user selection according to a defined wireless profile between each handheld device and the base unit;
wherein the base unit includes;
a base unit transceiver configured to receive the wireless selection signal, andbase unit logic configured to decode the wireless selection signal into the unique address and the user selection after receipt by the base unit device transceiver, generate a wireless acknowledgment signal including a representation of the unique address, and instruct the base unit transceiver to transmit the wireless acknowledgment signal according to the defined wireless profile,wherein the defined wireless profile between each handheld device and the base unit includes;
a distinct period of no wireless transmission,a first period of wireless transmission following the distinct period of no wireless transmission, the first period of wireless transmission including transmission of the wireless selection signal, where the first period of wireless transmission occurs upon receipt of the user selection at the input selection control, without receipt of a signal from the base unit to initiate transmission, anda second period of wireless transmission following the first period of wireless transmission, the second period of wireless transmission including transmission of the wireless acknowledgement signal.

Abstract
A handheld device is configured to communicate with a base unit in an audience response system having a multiplicity of handheld devices that are like in kind and perform a same function. The handheld device includes a transceiver, a user interface configured to receive a user response, a unique address identifying the handheld device, and signal generating logic configured to generate a radio frequency signal encoding the user response and the unique address. The handheld device further includes transmission logic configured to instruct the transceiver to repeatedly transmit the radio frequency signal upon receipt of the user response, without receiving a signal from the base unit to initiate transmission, until a termination event occurs. The termination event consists of one of a receipt of an acknowledgment signal from the base unit and an expiration of a predetermined period of time.

18. A base unit configured to communicate with a multiplicity of handheld devices in an audience response system, the base unit comprising:
-
a transceiver; processing logic configured to instruct the transceiver to operate in a non-transmission mode until a response signal is wirelessly received from one of the multiplicity of handheld devices in the audience response system; signal decoding logic configured to decode the response signal into address data that identifies one of the multiplicity of handheld devices and response data that identifies a user response, wherein the processing logic is further configured to; generate an acknowledgment signal including acknowledgment data and the address data, instruct the transceiver to transmit the acknowledgment signal, and instruct the transceiver to return to a non-transmission mode until a new response signal is wirelessly received from one of the multiplicity of handheld devices in the audience response system. - View Dependent Claims (19, 20, 21, 22, 23)
