TL;DR: In this article, a method and apparatus for determining the location of a communication unit in a CDMA system includes in a first embodiment, sending a location request via a spread spectrum signal to the subscriber (140), and receiving in return a subscriber signal including a response message showing a receive time of a particular symbol of the base's spreading sequence and a transmit time of the subscriber's transmission sequence.

TL;DR: In this paper, a method for determining a subscriber unit location in a communication system including the steps of receiving a signal from the subscriber unit (1390) at a first base station, determining a first receive time of the signal based on a sequence of spreading symbols at the first base stations, determining the first angle of arrival of a signal at the second base station and determining the location of the SU from the first received time, the first arrival time, and further predetermined information about the first BS.

TL;DR: In this article, a portable communication device (10) is controlled by voice recognition circuitry (20) remote from the portable communication devices, which includes apparatus for producing and transmitting a parametric representation of voice commands.

TL;DR: In this article, a method and apparatus for controlling the environmental conditions within a predefined area based on a network user's preferences using a personal area network is provided, which includes at least one portable communication unit associated with the network user, and has stored therein the environmental preferences (e.g., preferred temperature settings, lighting and sound conditions, etc.) of the network users for a given area.

TL;DR: In this article, a method and apparatus for assigning location estimates from a first transceiver of a plurality of wireless transceivers to a second transceiver is disclosed, which makes use of a low power short-range auxiliary communication link incorporated within networked devices to interact with nearby devices for obtaining location estimates of the current location of a device.
