Abstract
A wireless response system and method of receiving user input selections at a base station includes distributing a plurality of response units to users. The response units wirelessly communicate with the base station in order to retrieve user responses received by the response units. Each of the response units has a user input device that is configured to receiving user input selections, a controller that is responsive to the user input device to process user inputs and to communicate responses wirelessly to the base station and a power supply having a super capacitor. The super capacitor is charged with a wireless-charging circuit and current is supplied from the super capacitor to the controller. Current supplied to the controller is controlled.
