Machine condition assessment through power distribution networks

InactiveUS20100169030A1Eliminate needAlters the current and vibration characteristics of the machineVibration measurement in solidsElectric motor controlEmbedded systemTelecommunications equipment
A device, which is preferably embedded in a power distribution enclosure, enables analysis of conditions of electromechanical machines and, alternatively, also their driven or driver devices. The analysis uses operating voltages and currents supplied to or from the electromechanical machines. Since these voltages and currents are available at the enclosure, wiring or any other communication means to any sensors on the electromechanical machines or on the driver or driven devices are not necessary. The embedded device may optionally transmit its results to a computing or monitoring device remote from the enclosure, preferably wirelessly. The embedded device may receive all its power from an existing, conventional potential transformer in the enclosure, so that the embedded device may be retrofitted to the enclosure without the addition of any wiring external to the enclosure.

System And Method For Camera Imaging Data Channel

A system and method for using cameras to download data to cell phones or other devices as an alternative to CDMA / GPRS, BlueTooth, Infrared or cable connections. The data is encoded as a sequence of images such as 2D bar codes, which can be displayed in any flat panel display, acquired by a camera, and decoded by software embedded in the device. The decoded data is written to a file. The system and method meet the following challenges: (1) To encode arbitrary data as a sequence of images. (2) To process captured images under various lighting variations and perspective distortions while maintaining real time performance. (3) To decode the processed images robustly even when partial data is lost.

Controllable track-skipping

InactiveUS20030018797A1Good estimateRestricting skipping moreTelevision system detailsAnalogue secracy/subscription systemsComputer programDigital Millennium Copyright Act
A method, system, and computer program product allow users to skip and / or to fast-forward through media items such as songs, while limiting the extent to which skipping is allowed in order to maintain conformance with sound performance complement restrictions such as those specified by the Digital Millennium Copyright Act. If the user requests a skip that may result in a DMCA violation, the skip is disallowed and the request is denied. Playlists are constructed so that the sound recording performance complement limitations are applied to a longer time period than the period specified in the DMCA, the longer time period being defined by adding an "excess time" to the normal DMCA period. If the user attempts to skip a song or song portion that would cause the aggregated skipped amount to exceed the excess time, the skip is disallowed.

Uplink timing synchronization and access control for a multi-access wireless communication system

Improved timing synchronization and access control techniques for use in an orthogonal frequency division multiplexed (OFDM) wireless system or other type of wireless communication system. In accordance with the invention, an uplink synchronization and access control system is provided in which mobile stations transmit certain timing and access signals in dedicated intervals in an uplink stream. Access control is illustratively implemented as a two-stage process in which a given mobile first transmits a generic uplink access signal in one of the intervals. If this access is accepted, the base station transmits an access acknowledgment containing initial timing and power corrections, along with initial channel assignments on which the mobile can initiate a call set-up process. For re-synchronization, mobiles transmit timing synchronization signals in the dedicated timing and access intervals. The base station measures the arrival time of the signals, and sends back appropriate timing corrections. The invention thereby ensures that orthogonality between mobiles is maintained.

Physical resynthesis of a logic design

A multiple-pass synthesis technique improves the performance of a design. In a specific embodiment, synthesis is performed in two or more passes. In a first pass, a first synthesis is performed, and in a second or subsequent pass, a second synthesis or resynthesis is performed. During the first synthesis, the logic will be mapped to for example, the logic structures (e.g., logic elements, LUTs, synthesis gates) of the target technology such as a programmable logic device. Alternatively a netlist may be provided from a third party. Before the second synthesis, a fast or abbreviated fit may be performed of the netlist to a specific device (e.g., specific programmable logic device product). Before the second synthesis, the netlist obtained from the first synthesis (or provided by a third party) is unmapped and then the second synthesis is performed. Since a partial fit is performed, the second synthesis has more visibility and optimize the logic better than by using a single synthesis pass. After the second synthesis pass, a more detailed fit is performed.

Methods for analyzing and compressing multiple images

A multi-temporal, multi-angle, automated target exploitation method is provided for processing a large number of images. The system geo-rectifies the images to a three-dimensional surface topography, co-registers groups of the images with fractional pixel accuracy, automates change detection, evaluates the significance of change between the images, and massively compresses imagery sets based on the statistical significance of change. The method improves the resolution, accuracy, and quality of information extracted beyond the capabilities of any single image, and creates registered six-dimensional image datasets appropriate for mathematical treatment using standard multi-variable analysis techniques from vector calculus and linear algebra such as time-series analysis and eigenvector decomposition.
