A real-time method and system for locating a mobile object or person in a tracking environment. The method includes modulating a first carrier signal with a first packet including a first set of data to obtain a modulated first signal and transmitting the first signal. The first signal contains the first packet and has a first precision and a first range within the environment. The steps of modulating and transmitting are repeated until a modulated second signal is received within a time period after the step of transmitting. 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 second signal is demodulated to obtain the second packet. Location is determined within the environment based on the second packet.

Real-time method and system for locating a mobile object or person in a tracking environment

A response system and method of receiving remotely entered user input selections at a central location includes providing at least one base unit and a plurality of response units. A user input selection is received with each of the response units. The user input selection is communicated to the at least one base unit utilizing wireless communication. Personality data is received at each of the response units. The at least one base unit communicates with each of the response units according to the personality data of the particular one of the response units to receive a user input selection. The personality data is received by an individual one of the response units communicating with the at least one base unit at close proximity to provide personality data to that response unit.

Response system and method with dynamic personality assignment

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.

Real-time method and system for determining and validating location of a relocated mobile object or person in a tracking environment

A wireless response system and method of retrieving user selections includes providing a plurality of response units, each having a wireless response transceiver and an input device and a plurality of base units, each having a wireless base transceiver. The wireless response transceiver is adapted to transmitting a response transmission in response to receipt of a base transmission. The base transceiver is adapted to transmitting base transmissions and receiving response transmissions from the response units. Each of the base units and each of the response units are assigned communication identification. Base transmissions include a unique base address of the base unit transmitting that base transmission. Response transmission includes the base address of the base transmission to which that response transmission is responding. Each of the base units processes response transmissions having its base address and does not process response transmissions not having its base address.

Audience response system and method with multiple base unit capability

A response system and method of retrieving user responses from a plurality of users includes providing a plurality of base units and a plurality of response units, each of the response units adapted to receive a user input selection and to communicate that user input selection with at least one base unit utilizing wireless communication. Personality data is provided for the response units. The personality data facilitates communication with a particular base unit. The personality data of a particular one of the response units is changed in order to change which of the base units that response unit communicates. This allows a response unit to become grouped with a particular base unit at a particular time and become grouped with another base unit at another particular time. The personality data may be obtained from a database.

A wireless communication system and method includes providing at least one master unit and a plurality of slave units communicating with the at least one master unit over at least one wireless communication link. The at least one master unit sends polling signals to the slave units over the at least one wireless communication link. The slave units send data to the at least one master unit over the at least one communication link in response to one of the polling signals. The communication link is made up of at least one master transceiver at the at least one master unit and a plurality of slave transceivers each at one of the slave units. The at least one master transceiver and the slave transceivers communicate with a spread-spectrum hopping protocol.
