Method and system for controlling neighbor scanning in a subscriber unit in a cellular communication system

Abstract: In a cellular communication system, a plurality of neighbor scan lists are generated and associated with a selected cell in the cellular communication system, wherein each neighbor scan list includes selected neighbor identifiers. Thereafter, a present operating mode, of a plurality of operating modes, of a subscriber unit communicating with the selected cell is determined. In response to the present operating mode of the subscriber unit, the subscriber unit is configured to scan a neighbor scan list selected from the plurality of neighbor scan lists for the selected cell. The operating modes of the subscriber unit may include an idle mode and an active mode.

Functionalized polynorbornene dielectric polymers: Adhesion and mechanical properties

Abstract: Within the microelectronics industry, there is an ongoing trend toward miniaturization coupled with higher performance. High glass-transition temperature polynorbornenes exhibit many of the key performance criteria necessary for these demanding applications. However, homopolynorbornene exhibits poor adhesion to common substrate materials, including silicon, silicon dioxide, aluminum, gold, and copper. In addition, this homopolymer is extremely brittle, yielding less than 1% elongation-to-break values. To address these issues, the homopolymer was functionalized to improve adhesive and mechanical properties. Attaching triethoxysilyl groups to the polymer backbone substantially improved the adhesion, but at the cost of increasing the dielectric constant because of the polarity of the functional group. Alkyl groups were also added to the backbone, which decreased the rigidity of the system, and resulted in significantly higher elongation-to-break values and a decrease in residual stress. The addition of an alkyl group slightly decreased the dielectric constant of the polymer as a result of an increase in molar volume. The coefficient of thermal expansion and modulus are also reported for the polynorbornene functionalized with triethoxysilyl groups using a multiple substrate approach. © 1999 John Wiley & Sons, Inc.

Integrated circuit having both vertical and horizontal devices and process for making the same

Abstract: An integrated circuit (10) has a vertical device, such as a transistor (71), formed by epitaxial growth from a substrate (12) and a horizontal device, such as a transistor (73, 75) grown epitaxially from the vertical device. In accordance with one embodiment of the invention, all six transistors of an SRAM cell can be formed in single crystal material for improved device characteristics and increased cell density. Utilization of various combinations of vertical and horizontal devices permits a large degree of vertical integration within semiconductor devices.

Wearable display device, corresponding systems, and method for presenting output on the same

Abstract: An electronic device can include detectors for altering the presentation of data on one or more displays. In a wearable electronic device, a flexible housing can be configured to enfold about an appendage of a user, such as a user's wrist. A display can disposed along a major face of the flexible housing. A control circuit can be operable with the display. A gaze detector can be included to detect a gaze direction, and optionally a gaze cone. An orientation detector can be configured to detect an orientation of the electronic device relative to the user. The control circuit can alter a presentation of data on the display in response to a detected gaze direction, in response to detected orientation of the wearable electronic device relative to the user, in response to touch or gesture input, or combinations thereof. Secondary displays can be hingedly coupled to the electronic device.

Interference mitigation in a device having multiple radios

Abstract: A wireless terminal that supports operation on a first wireless technology and operation on a second wireless technology performs a first set of measurements on a received signal on first operating frequency of the first wireless technology, wherein the first set of measurements are performed during time periods that overlap time periods during which the wireless terminal transmits signals of the second wireless technology. The terminal also performs interference avoidance to avoid interference from transmissions of signals of the second wireless technology to reception of signals of the first wireless technology if the first set of measurements indicates interference due to transmission of signals of the second wireless technology by the wireless terminal.
