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.

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.

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.

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.

The at least one second device is attached to the charge storage capacitor and adapted to read a rate of charge storage in the charge storage capacitor or to calculate the rate of charge storage by measuring both a time of charging and a charge stored or added to the charge storage capacitor during the time of charging.

Methods and apparatuses for improved position determination of a device using multiple pseudo range measurements from transmitting sources at known locations, such as GPS satellites. A plurality of pseudo range measurements for each transmitting source are processed together to obtain a simplified maximum likelihood estimate for the pseudo range for that transmitting source at a common reference time. The processed pseudo range estimates for all transmitting sources are then combined using conventional position determination algorithms. This technique facilitates removal of raw measurement outliers prior to position determination, which results in improved (i.e., more accurate) position fixes of the device. In addition, improved measurement integrity monitoring of the pseudo range measurements is a feature of this invention.

An apparatus and method for transmitting/receiving an random access channel (RACH) signal in a broadband wireless communication system where a total uplink frequency band is divided into M sub-bands are provided. In the RACH transmitting apparatus, a generator generates an access code. A sub-carrier allocator divides the access code into M sub-blocks and allocates each of the M sub-blocks to successive sub-carriers in a sub-band. An inverse fast Fourier transform (IFFT) processor generates an orthogonal frequency division multiplexing (OFDM) symbol by performing an IFFT on the allocated sub-blocks.

A display method and apparatus for navigation system enables a user easily see a list of points of interest (POIs) along a route to a destination. The POI names are arranged in the order that the user sees the POIs along the route. The method first determines a route to the destination, and specifies a search area by selecting a distance range on the route from a user position and by defining a radius of a region circle. The method further creates a plurality of region circles consecutively on the route, retrieves points of interest (POIs) within the search area, calculates a modified distance of each POI based on distances from two reference points to the POI and distances from the user position to the two reference points, and lists the POIs in the order of modified distance.

The present invention relates to a method and apparatus for monitoring haemodynamic function in animals and humans during anaesthesia and surgery. During anaesthesia and surgery the subject's haemodynamic, respiratory, neuromuscular and neurological functions are monitored as indicators of the condition of the health of the subject. Commonly, variations in blood pressure are used to imply corresponding variations in cardiac output, i.e. good blood pressure equals good cardiac output. The present invention utilizes a device to monitor changes of blood flow in peripheral blood vessels of the subject as an indicator of cardiac output. This is believed to provide a much more accurate indicator.

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.
