Abstract: Circuits, methods, and apparatus that provide a precise phase shift for a read strobe or other signal. One embodiment provides a read strobe delay line including a series of delay elements, where inputs or outputs of at least some of delay elements are received by a multiplexer.

Abstract: Valve structures formed in elastomer material are electrostatically actuated by applying voltage to a flexible, electrically conductive wire pattern. An actuation force generated between the patterned wire structure and an electrode result in closure of a flow channel formed in elastomer material underlying the wire. In one embodiment of a valve structure in accordance with the present invention, the wire structure is patterned by lithography and etching of a copper/polyimide laminate, with an underlying gold plate positioned on the opposite side of the flow channel serving as an electrode. In an alternative embodiment, a first wire structure is patterned by physically cutting out a first pattern of strips from an Aluminum/Mylar(®) laminate sheet. A second patterned wire structure serving as the electrode is formed by the same method, and positioned on the opposite side of a control channel.

Abstract: A time indicator comprising a first reservoir (13), a migration medium (11) and activating means for bringing liquid from the first reservoir (13) in contact with the migration medium (11) so that after activation the liquid migrates through the migration medium (11) producing a colour change therein. The activating means comprises a second reservoir (16) connected between the first reservoir (13) and the migration medium (11) whereby after activation the liquid travels relatively rapidly from the first reservoir (13) to the second reservoir (16) and then migrates relatively slowly along the length of the migration medium (11) over time.

Abstract: A method and apparatus for rendering shadows. A pre-rendering process implements a two dimensional array or map of depth-based functions, such as a visibility function in z. During rendering of an object scene, these functions are accessed via lookup operations to efficiently determine the function value for a sample point at a given depth. The use of visibility functions allows for partial light attenuation effects. Each visibility function is computed by filtering multiple transmittance functions obtained by casting sample rays from a light source onto an object scene. The visibility function is implemented as a sequence of vertices. Colored shadows are modeled by vertices comprising a depth value and separate visibility function values for red, green, and blue light at a given depth value. Compression is achieved by minimizing the number of vertices needed to represent a visibility function within a desired error tolerance.

Abstract: Accordingly, embodiments of the present invention provide circuits, methods, and apparatus that improve utilization of storage buffers by overwriting data in them as soon as the data is no longer needed. An exemplary embodiment employs a counter to add each time a particular unit of data is needed by a circuit. The counter also subtracts each time the data is actually used by the circuit. When the counter reaches zero, upstream circuitry is checked to see if a command allowing the particular data to be overwritten has been issued. If it has, the command is not waited for, rather the data may be overwritten immediately. Embodiments of the present invention may also make use of one level of indirection to mask physical storage buffer locations from upstream circuitry. In this way, utilization can be improved.

Abstract: A system receives input data frames that are configured according to a SONET or an SDH standard. The input data is converted to parallel data. The system provides groups of bits along parallel signal lines. In each group of bits, N contiguous bits in the group form a complete word of input data. The system identifies the boundary between complete words in the input data by comparing subsets of the bits to predefined framing patterns. The system then aligns the input data based on the location of each word using the boundary information. The output data of the system includes data that is word aligned. The system can also detect boundaries between the frames.

Abstract: A system and method is provided for monitoring the activities and/or locations of wireless units in a wireless network independent of location-based service preferences of those wireless units. That is, a system and method is provided that allows an authorized requester override location-based service preferences (e.g., privacy settings) that may be set for a wireless unit. In this regard, an authorized entity may be able to effectively locate and/or monitor the activities of a wireless unit associated with an individual of interest. Furthermore, if proper authorization exists, such monitoring may be done surreptitiously without the wireless unit user's knowledge and/or consent. For example, in some instances, law enforcement agencies may be authorized to monitor call traffic and/or the location of persons utilizing wireless units.

Abstract: A door assembly having a structural inner frame that is secured between an interior sheath and an exterior sheath. The inner frame provides rigidity and strength to the door assembly and will not warp or otherwise lose its dimensional integrity regardless of the environment or usage. Both the interior and exterior sheaths add strength and durability once attached to and combined with the inner frame. The internal frame is formed from metal, wood, plastic, composite panels, polystyrene panels or other structural materials. In the preferred embodiment, the inner frame by itself is not structural, it relies on the interior sheath and exterior sheath for its combined strength. The components of the internal frame are secured together by fastening onto the interior sheath and exterior sheath. This allows the components, while structurally supporting one another, to utilize the interior and exterior sheaths to fasten the components to one another.

Abstract: Apparatus and methods, including computer program products, for providing a network-accessible queue. The queue is stored on a network-accessible file system having a locking mechanism providing strictly-enforced, network-wide file locking. The data structures of the queue are stored in the file system. The file system is preferably implemented on a network accessible RAID array storage device providing a native CIFS file system for storing queue entries received over a network from sender clients and for delivery of such queue entries to receiver clients. Synchronization is implemented using file locks enforced by the file system, so there is no need for a master synchronization process. Notification of the availability of queue entries to receiver clients is also done by a decentralized process.
