Abstract
A controller that communicates with a first set of devices and a second set of devices is disclosed. The controller includes a transmitter for transmitting commands to remotely control the first set of devices, and for communicating input/output (I/O) data with the second set of devices. A microphone, speaker, display and cellular and cordless phone circuitry are integrated into the controller to provide the controller with phone and paging capabilities. Systems for determining the spatial location of a target object are also disclosed. The spatial location of the target object is determined with reference to a predetermined spatial reference point based on measured elapsed times, which represent the difference between a time reference and the time of receipt of a location signal from the target object at the known locations.
