Filed:

Feb 20, 2009

Appl. No.:

12/390386

Inventors:

David Lee Erickson - San Jose CA, US

Assignee:

iControl, Inc. - Santa Clara CA

International Classification:

G08B 21/00

US Classification:

340540, 34053926, 340521, 3405681

Abstract:

Monitoring data is received from a remote device and represents a current status value of a monitored condition at the remote device. The monitored condition is characterized by a current state that can be any one of a number of possible states. A determination is made as to whether the current status value of the monitored condition as indicated by the received data satisfies a hysteresis criterion associated with the current state of the monitored condition. If the current status value of the monitored condition satisfies the hysteresis criterion, then a determination is made as to whether the hysteresis criterion has been continuously satisfied for a specified persistence period. If the hysteresis criterion has been continuously satisfied for the specified persistence period, then the current state of the monitored condition is changed to reflect the current status value of the monitored condition, and the changed current state is recorded.

US Classification:

382103, 382105, 382104, 705 28, 705 6

Abstract:

An unknown named territory encloses a known physical target location that is specified by a target longitude and a target latitude. An operation is performed to identify a number of rectangular-shaped terrestrial areas that each enclose both the target longitude and the target latitude. Each of the identified rectangular-shaped terrestrial areas respectively encloses a polygonal-shaped named territory. Each polygonal-shaped named territory is defined by a respective circumscribing set of contiguously positioned vectors. An operation is performed to evaluate the circumscribing sets of contiguously positioned vectors of the polygonal-shaped named territories to determine if a given polygonal-shaped named territory includes both the target longitude and the target latitude. When both the target longitude and the target latitude are found to reside within a given polygonal-shaped named territory, the identity of the given polygonal-shaped named territory is conveyed.

Abstract:

A processor for a cable television set-top box has an interface for coupling the processor to a second processor. The processor also has a port that is coupleable to control a tuner, a demodulator and a DOCSIS module with or without DSG support. The tuner has an output coupled to the demodulator input, and the demodulator has an output to the DOCSIS module input. The demodulator's output is also coupled to a conditional access module controlled by the second processor. The processor issues commands via the port to control at least one of the tuner and the demodulator based on instructions received via the interface from the second processor.

International Classification:

H04L 9/32

US Classification:

713171, 713168

Abstract:

A first hash result is generated at a client system in accordance with hash input parameters known to the client system. A second hash result is generated at a server system in accordance with hash input parameters known to the server system. Each of the first hash result and the second hash result is truncated in a same manner. The truncated first hash result is transmitted from the client system to the server system. The truncated first hash result as transmitted to the server system is compared with the truncated second hash result generated at the server system. Equality between the truncated first hash result as transmitted to the server system and the truncated second hash result generated at the server system authenticates the client system to the server system.

Abstract:

A method is provided for fabricating a nanochannel. The method comprises providing a microchannel and controlling collapse of the microchannel so that it collapses to form a nanochannel of desired dimensions. The method employs a collapsible, flexible material such as the elastomer polydimethylsiloxane (PDMS) to form the nanochannel. A master is provided that is configured to have geometric conditions that promote a desired frequency of microchannel collapse. A collapsible material having a stiffness that also promotes a desired frequency of microchannel collapse is molded on the master. The molded collapsible material is removed from the master and bonded to a base, thereby forming the microchannel, which then collapses (or is collapsed) to form the nanochannel of desired dimensions. Nanofluidic and microfluidic devices comprising complex nanochannel structures and micro to nanochannel transitions are also provided.

Abstract:

A video stream demultiplxer receives video streams comprising a selected current content channel and one or more adjacent content channels. Time stamp management is concurrently performed on the adjacent content channels while decoding the selected current content channel. Timing information such as Decoding Time Stamp (DTS) and Presentation Time Stamp (PTS) values, and/or random access points (RAPs) may be determined for pictures stored for the selected current content channel and the adjacent content channels. The determined timing information is utilized to determine a Program Clock Reference (PCR) value for each of the selected current channel and the adjacent channels for channel monitoring. A timebase, derived from a PCR rate that is determined based on the determined PCR value, is determined for decoding the selected current content channel. An adjacent content channel, which is primed during decoding of the selected current content channel, may be directly decoded for display if selected.
