IPC: G02B6/38
Filed: 1998-03-20
Abstract: The present invention relates to optical connectors and concerns a connector (1) for connecting at least one optical fibre (2) in a so called integrated optical interface, wherein a ferrule fibre end, in order to contact a second ferrule fibre end, is pressed towards said second end and is retained in this position. Because the first ferrule (11), creating the optical interface, is placed just outside a wall in an opto electrical component (3), and the second ferrule (6), a same kind of or similar ferrule, is placed inside the connector (1), a possibility is formed to mutually align two optical fibres in a cost efficient way. In order to retain the contact between the fibre ends in a contact position, the connector (1) comprises two hook members (12), the hooked ends (13) of which can be hooked into grooves (14) provided in the component (3). To release the connector from the component, only a slight pressure needs to be applied to the hook elements, whereby the hooked ends of the hook elements are released from the grooves, and the connector can be separated from the component.

Title: Electrostatic adhesion tester for thin film conductors
Inventor: GRIFFIN ALFRED J JR
IPC: G01N19/04
Filed: 1998-03-31
Abstract: An electrostatic adhesion tester for thin film conductors. In one embodiment, a device is provided for testing the adhesion strength of a thin film conductor that has been formed upon a substrate. The device includes an adhesion tester that is primarily comprised of a conducting portion. The conducting portion is applied to the thin film conductor so that it does not physically contact the thin film conductor, but leaves a small space therebetween. A power supply may further be provided for coupling to either the adhesion tester, the thin film conductor, or both in order to create a potential difference between the conducting portion and the thin film conductor. The potential difference creates an electric field between the conducting portion and the thin film conductor that induces stress in the thin film conductor. A measuring device may also be provided for coupling to the adhesion tester and the thin film conductor in order to measure an electrical parameter of the electric field, which is indicative of the adhesion strength.

Title: Power adaption in a multi-station network
Inventor: LARSEN MARK SIEVERT
IPC: H04B7/005
Filed: 1998-08-03
Abstract: The invention relates to a method of operating a communication network, the network comprising a plurality of stations which are able to transmit data to and receive data from one another. The method comprises monitoring, at each station, the transmission path quality between that station and each other station with which that station can communicate. Data corresponding to the monitored path quality is recorded at each station, thereby permitting a transmission power value based on the relevant path quality data to be selected when transmitting data to another station. Thus, the probability of transmitting data to any selected station at an optimum power level is increased. Each station transmits path quality data in its own transmissions as well as local noise/interference data, so that other stations can obtain path quality data for a particular station even if they are out of range of that particular station. The invention extends to communication apparatus which can be used to implement the method.

Title: Light separation and recombination system for an off-axis projector
Inventor: SCOTT BRADLEY A
IPC: H04N9/31
Filed: 1998-10-13
Abstract: A color separation and recombination system separates a beam of white light traveling along an optical axis into three differently colored light beams. The system then independently modulates each colored beam and recombines the colored beams to create a color image.      The system includes a crossed pair of dichroic filters to separate the beam of white light and to recombine the modulated bundles. The system also includes a pair of aberration-compensating elements that equalize the optical thickness of glass through which each light bundle passes.      This equalization of optical thickness equalizes the aberration induced into each bundle. In another embodiment the beam of white light is polarized before separation. The polarities of the colored light beams are then modulated using a spatial light modulator. An analyzer and half-wave plate are provided between the spatial light modulator and the crossed dichroic filters to pass only a portion of the modulated light. The half-wave plate ensures that the modulated light incident on the crossed dichroic filters is of the same polarity as was the polarized white light separated by the crossed dichroic filters.

IPC: G02B6/42
Filed: 2000-05-02
Abstract: A vertical cavity surface emitting laser (VCSEL) and monitoring diode combination having reduced parasitic capacitance for use in high bandwidth communications systems. The VCSEL has both p-type and n-type contacts on the same face. This allows the VCSEL to be mounted on a monitor chip or diode without using a metal contact layer. In an embodiment wherein the VCSEL is soldered to the monitor chip for mechanical stability only a small metal pad no larger than the VCSEL is used. The reduction in metallisation results in a lower parasitic capacitance that in turn results in higher potential operational speeds

Abstract: An uncoordinated frequency hopping cellular system includes a mobile unit and a number of base stations. The mobile unit determines which base stations are in a geographical location defined by a location of the mobile unit. This determination is made by transmitting one or more inquiry messages, and receiving response information transmitted by responding base stations. The mobile unit then selects, for use by the mobile unit, one of the base stations from the set of base stations. Each of the base stations receives at least one of the inquiry messages, and transmits the response information to the mobile unit in response to the at least one received inquiry message. The mobile unit determines synchronization information from the response information, and uses this to establish communication with the selected base station.
