Patent TW-297972-B (TW)
IPC: H04B7/26
Filed: 1995-12-12
Granted: 1997-02-11
Abstract: A system and method for using a sectored antenna arrangement within a cellular base station to provide redundant coverage within the surrounding cell is disclosed herein. An antenna feed network connects elements of the sectored antenna arrangement to a set of communication transceivers, wherein the feed network includes a combiner array for combining selected ones of the antenna beams upon failure of one of the communication transceivers. A switch network serves to provide the resultant combined beam to an operative one of the communication transceivers. Alternately, the sectored antenna arrangement includes an antenna array having a plurality of switchable antenna elements, each connected to one of the communication transceivers. The switchable antenna elements project a set of variable-width antenna beams over the plurality of cell sectors. Upon one of the communication transceivers becoming inoperative, an antenna control network operates to adjust beam width of a selected one of the variable-width antenna beams by switching configuration of an associated one of the switchable antenna elements. In another approach each antenna within a primary array is disposed to project a beam over a single sector, while each element within a redundant array is designed to encompass a pair of adjacent sectors. Upon one of the transceivers becoming inoperative, a transceiver nominally assigned to cover a sector neighboring the failed sector is connected to the element within the redundant array encompassing both the failed and neighboring sectors.

Title: Method and apparatus for electronically embedding directional cues in two channels of sound for interactive applications
Inventor: WOOD PAUL NIGEL
IPC: H04S1/00
Filed: 1998-01-20
Granted: 2001-05-01
Abstract: A system for providing audible cues that enable a listener to identify locations of origins of sounds. In one embodiment, a front and rear signal are copies of an input signal. The rear signal is modified by application of a modified head related transfer function which is the difference between the front and rear head related transfer functions. Copies are then made of the front signal and the modified rear signal, one copy of each associated with a first channel and one copy of each associated with a second channel. Front/rear cues are applied by delaying one of the rear signals or inverting the phase of one of the rear signals. Volume levels are then modified according to the location of the sound source. Locations of sound sources, including sources location behind the user are therefore audibly distinguished. Thus, in an interactive environment, such as a video game environment, the sounds generated by moving objects can be readily modified by simply modifying the volume levels.
