摘要： Received echo data are transferred from an ultrasound probe to the signal processing circuitry of an ultrasound imaging system by use of a reduced number of multiple coaxial cables. The system operates by frequency division multiplexing of the analog output signals produced by multiple individual array elements in the probe onto a single coaxial cable, which connects the probe to the central host computer or console for conventional signal processing and imaging.

摘要： A system and method involve tracking the location of objects within an area of interest using transmitted-reference ultra-wideband (TR-UWB) signals. The system includes at least three base stations communicating with a central processor, at least one mobile device and at least one fixed beacon transmitter of known location. The mobile device is equipped with a transmitter for transmitting a TR-UWB signal to a base station, which then determines a location of the mobile device based on time difference of arrival information between the beacon transmitters and mobile devices measured at all the base stations. Preferably, the area of interest includes a plurality of mobile devices each transmitting a delay-hopped TR-UWB signal according to a code-division multiple access scheme. The mobile devices may be attached to a patient and/or a medical asset within the hospital for tracking purposes. Additionally, patient medical information may be transmitted with the TR-UWB signals to allow patient monitoring to occur simultaneously with asset/patient tracking.

摘要： A spread spectrum protocol in a power line communication (PLC) system uses Harmonic Modulation (HM) as true spread spectrum modulation made up of a plurality of modulated tones spaced in frequency with equal distance between adjacent tones. The protocol incorporates the following modes:"Conventional"--Master/Slave relation of meters to a common hub."Leap Frog"--performing data relay through locally elected/designated meters for relay to a central hub or a distributed set of concentrators."Alarm Channel"--reserving an HM signal set for meters to telemeter their configuration in a subnetwork after a power distribution network reconfiguration."Probing"--using HM polling to diagnose the location of a feeder fault."Derived Timing"--master derived timing for inbound message framing."Rate Adapting"--allocating a mix of number of HM channels to the outbound/inbound ratio according to message traffic control requirements and power line distribution topology."Priority/Noise Based Adapting"--allocating a different mix of number of HM channels to the outbound/inbound ratio based on message priority or noise conditions.

摘要： A system for filtering digital television signals is provided. The system comprises a generator for providing a first data sequence to a private data packetizer, and a transmitter for transmitting the packetized first data sequence in a data channel of a digital television signal. The system further includes a receiver for receiving the digital television signal and recovering the first data sequence. The receiver includes a channel estimator for providing an estimate of channel characteristics, such as estimated channel impulse estimate and estimated noise variance. The receiver further includes an adaptive equalizer filter having an input for receiving the digital television signal and an input for receiving adaptive filter coefficients. The receiver further includes a coefficient processor for calculating adaptive filter coefficients based on the channel estimate, and providing the adaptive filter coefficients to the adaptive equalizer filter. The digital television signal is thus filtered to remove undesired channel effects.

摘要： A wide-band overlay sequence generator adds an overlay signal to a television signal which is transmitted through a channel. At a receiver, a replica of the transmitted overlay sequence is generated and synchronized to the overlay signal in the received signal. An adaptive equalizer filter effectively adjusts the received television signal so that the channel perturbations are removed from the signal.

摘要： A system to monitor the integrity of a railway track is provided. The system comprises a mechanical signal source and a correlation detector. The mechanical signal source coupled to the railway track and is configured for generating a mechanical signal pulse train over the railway track. The correlation detector monitors the integrity of the railway track by observing the pulse trains transmitted by the mechanical signal sources. If the railway track is intact, then the pulse train will travel to the correlation detector and afford the opportunity for repeatable detection.

摘要： The present techniques provide systems and methods for modulation coding of data on optical disks, such as holographic data disks, and techniques for reading that data back from the disks. The techniques involve parsing a bit stream into a sequence of individual bit-patterns, and then using the individual bit patterns to select a symbol, or matrix, from a lookup table of previously selected matrices. The symbols are selected according to predetermined criteria that may help make the disk more resistant to interferences and errors, such as surface scratches, and the like. For example, criteria that may be used to select the symbols are the number of reflective and non-reflective regions within each matrix, and the number of sequential reflective regions, among others. The symbols may be written to the disk in a two-dimensional fashion, e.g., across adjacent tracks, or in a three-dimensional fashion, e.g., across adjacent data layers.

摘要： The present techniques provide methods and systems for reading and processing a data signal read from an optical data disc. In embodiments, an optical reader system may read data bits from a data ring in the disc. The data rings may be concentric, and a beginning of a sequence of data on the data ring may be in substantially the same position as an ending of the sequence. The reader may identify a data ring and begin the read process on the targeted data ring, and may end the read process when the reader reaches the starting point. The data sequence read from the data ring may be decoded to form a bit stream, which may be provided to various output devices. A circular trellis formed from the bit stream may enable the reading of a targeted data sequence without additional tail bits to improve data transmission efficiency.
