摘要:
A real-time method and system of determining and validating location of a relocated mobile object or person in a tracking environment in which a plurality of sensors are located are provided. The method includes modulating a first carrier signal with a first packet including a first set of data to obtain a modulated first signal. The first signal contains the first packet and has a first precision and a first range within the environment. A modulated second signal is received from at least one of the sensors including the nearest sensor. The second signal contains a second packet including a second set of data and has a second precision and a second range within the environment. The method further includes determining and validating current location of the relocated tag within the environment based on a plurality of second packets.

摘要:
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.

摘要:
An interactive response system (20) includes a central control host system (22) and one or more wireless remote systems (23) geographically separated from the host system and interconnected with the host system through a communication network. Each remote system includes a base unit (26) and a plurality of response units coupled with the base units through a wireless communication link. Each of the response units includes a microphone (46), a user input device and a control. Audio signals entered through the microphone are communicated over the wireless communication channel to the base unit and over the communication network to the host system. Any inputs entered on the input device are communicated over the wireless communication channel to the base unit. The host system includes an instructor selection device and a display. At least one call list is displayed on the display. The instructor selects characteristics of individuals for inclusion on the call list. Individuals requesting to have an audio link with the instructor are placed on the call list if a characteristic of theirs from a database roster matches the characteristic set up by the instructor for that call list.
