  • Wireless point to multi-point communication apparatus and method
    Patent number: 7006794
    Abstract: A wireless communication system that provides energy efficient, high bandwidth and low cost wireless communication. In one embodiment, the communication system utilizes a fan out, pencil beam arrangement in which electro-magnetic energy is transmitted from a hub to customer premises equipment (CPE) with a fan or similar antenna and from the CPEs to the hub via pencil beam antennas. The pencil beam antennas provided higher link margin. The hub may include a shared aperture antenna device for receiving pencil beam transmissions from the CPEs. A shared aperture antenna device may also be used for transmission from the hub to the CPEs.

  • Sectorized multi-function communication system
    Patent number: 6052582
    Abstract: The preferred embodiment of the present invention is a communications apparatus which includes a first transmitting antenna array (15A) having a transmitting antenna (16) which is dedicated to serve only a first sector (12). Similarly, a second transmitting antenna array (17A) having a transmitting antenna (18) is dedicated to serve only a second sector (14). Each of the transmitting antenna arrays (15A, 17A) have a beamwidth (19) of generally less than fifteen degrees. Both the first and the second transmitting antenna arrays (15A, 17A) emanate shaped beams which are alternately polarized to ensure the isolation of beams that serve adjacent sectors.

  • Processing microchips
    Patent number: 5411918
    Abstract: Uniaxially conductive connector formed in situ on microchip by laser drilling an insulating layer at least 5 micrometers thick to provide holes communicating with the chip bonding sites, and depositing metal in the holes to establish electrical connection with the bonding sites. Excimer U.V. laser ablation of a polyimide insulating layer is preferred, followed by removal of a surface layer (preferably of amorphous polyamide from the insulating layer to expose the ends of the metal deposited in the holes.
