Abstract: A dynamic context filter for communication and information management filters information using dynamic parameters corresponding to a particular user. Dynamic context filters may represent user location, current time, or past preferences. Filtered information may be prioritized based on proximity, time, or past preferences. The importance of dynamic context filter parameters may be weighted.

Abstract: An enhanced cellular layout for cellular networks having six-sectored cells is disclosed. In one embodiment, the cellular layout is implemented by rotating directional antennas located at each cell site of a triangular cellular layout of a six-sectored CDMA network clockwise or counterclockwise by approximately 10.893.degree. or rotating directional antennas located at each cell site of a parallelogram cellular layout of a six-sectored CDMA network clockwise or counterclockwise by approximately 19.107.degree..

Abstract: A discontinuous ring is formed by separate bidirectional optical communication links, with possibly different transmission speeds, synchronous or asynchronous transmission, and ratios of working to protection channels, each linking a pair of terminals in different nodes of a communication system. To protect protection-switched traffic on a communication link from a link failure, it is routed around the ring via the protection channel of the other communication links. To this end, an optical switch is provided between the protection channel of each link and the associated terminals in each node, and is controlled differently in nodes adjacent the link failure and in nodes not adjacent the link failure to route the protection-switched traffic accordingly. Rapid protection switching is facilitated by controlling the optical switches using wavelength detectors directionally coupled to the protection channel at each node.

Abstract: A service methodology for time based availability to content, such as, movies, music, games, information and the like, provisioned on a storage medium whereby revenue may be generated for premier and pay-per-use access to the content. The service is manifested by the combination of a video disk reader, controller and authorization center. A service provider, for instance, locks up a movie on a video disk for which a premier event viewing date and time may be defined and which the provider may then directly distribute, in advance of the premier event, to potential consumers. Each consumer may purchase the right to view the movie once for a certain fee, for example $5.00, through online access from the controller to the authorization center, but the single viewing will only be allowed by the controller on or after the premier event. Thereafter, the consumer pays for viewing of the movie on a pay-per-use basis or over a defined window of time, perhaps for reduced fee, such as $1.00.

Abstract: A method and apparatus are provided for coupling light from a fiber to a waveguide on an OEIC (optoelectronic integrated circuit). The region of the fiber to be connected is made into a D-fiber by removing a portion of its cladding. The flat surface is fused to a silicon dioxide coated portion of the waveguide. The light in the fiber is evanescently coupled into the waveguide on the OEIC which is typically a planar or channel waveguide.

Abstract: In order to provide for clocking master/slave flip-flops in complex circuits by means of non-overlapping two-phase clocks, a clock generator for providing two clocks signals for use with two-phase flip-flops, comprises a settable latch and a gating device. The settable latch has a data input connected to a reference source, a set input connected to receive one of the two clock signals and a clock input connected to receive the other of the two clock signals. The gating device has one input connected to receive such one of the two clock signals and a second input connected to the output of the settable latch. The output of the gating device, which corresponds to the other of the two clock signals, is connected to the clock input of the settable latch, the arrangement being such that when the settable latch has been set by a transition of the one clock signal resetting of the settable latch is enabled by the other clock signal.
