摘要： A location system and method for determining the location of a tagged item in a facility. In one embodiment, the location system includes a plurality of room transmitters designed to be located throughout the facility. Each room transmitter has a unique signature. The system also includes at least one item or location tag affixed or otherwise associated with an item. Each tag is operable to send a signal having information related to the signature of a room transmitter within the reception range of the tag and information related to the identity of the tag. Signals from the tags are received by one or more locating receivers. Each locating receiver is operable to determine the identity of an item tag and the likely location of the item tag within the facility based upon the signal from that tag. The invention also provides a method of locating an item in a facility. In one embodiment, the method includes positioning room transmitters in multiple areas within a facility; configuring each room transmitter to generate a unique signature; fitting items with a tag; configuring each tag to generate a signal having a location portion and a signature portion; positioning a locating receiver within the facility; and determining the likely location and identity of that tag based on the tag's signal.

摘要： A method for calibrating cameras includes moving a point of light on a first flat surface. A first and a second camera are capable of generating a first frame and a second frame of the point of light respectively. The respective points of light are in a first and a second field of view of the first and second camera. The method includes determining a relative position between the first camera and the second camera based in part on the first frame and the second frame.

摘要： An Advanced Television Standards Committee (ATSC)-compliant pilot tone is generated within an 8-VSB (eight level vestigial sideband) transmission in order to enable Quadrature Amplitude Modulation (QAM) receiver designs to more efficiently process the transmitted/received 8-VSB signal. The method and apparatus also efficiently removes the pilot tone before using conventional QAM demodulator equipment for directly demodulating the 8-VSB signal.

摘要： An N-VSB (vestigial sideband) modulation signal is converted into an M-QAM (quadrature amplitude modulation) signal, where M=N2, by shifting the symbol rate frequency of a received N-VSB modulation signal to center the waveform spectrum about zero Hertz prior to complex demodulation so that data symbols will alternately appear on demodulated I and Q channels. A pilot tone of the received N-VSB modulation signal is removed to eliminate any bias in the both I and Q channels. Symbol timing between I and Q channels is offset, and quadrature amplitude demodulation of the I and Q channel signals generate alternating I and Q channel data symbols. Alternating inversion of the alternating I and Q channel data symbols recovers the N-VSB symbol data.

摘要： A system for communicating digital information over wires having a great deal of harmonic distortion, such as a power line, employs a transmitter which transmitter which creates a carrier wave for each of a plurality of signals to be sent. This carrier wave has frequency lobes positioned between the frequency lobes of the harmonic distortion. Each of the lobes of a single carrier signal is encoded with the same bit value during a given bit period. This signal is then mixed with any existing signal on the wire. At a remote receiver coupled to the wires, the signal is sensed, filtered, and Fourier transformed into coefficients. The signal-to-noise (S/N) ratio of each Fourier coefficient is determined by a novel S/N estimation technique. The coefficients are weighted based upon the S/N ratio estimation, and decoded, preferably by an inner product of the weighted Fourier coefficients. Additionally, the S/N ratio estimates could be time averaged before being used in the weighting and bit decoding.

摘要： A junction box architecture includes a main circuit breaker, plurality of branch circuit breakers, and an arc detection unit. The main circuit breaker input is connected to main power supply lines, e.g., phase 1 and phase 2 power lines. The main circuit breaker output is connected to respective inputs of branch circuit breakers and to an input of the arc detection unit. The arc detection unit includes an enable output and is configured to generate an enable signal on the enable output. The enable output is coupled to enable inputs of each branch circuit breaker. When no enable signal is present on an enable input of any one branch circuit breaker, the one breaker will not trip. In general, for any one circuit breaker to trip, the breaker must simultaneously detect a high frequency current in the associated branch circuit and receive an enable signal from the arc detection unit.

摘要： A pressure sensor having structure for generating a magnetic force to balance forces on opposing sides of a flexible diaphragm centered within a pressure chamber allows fluid pressure to be introduced into the chamber on one side of the diaphragm. A first magnetic coil is positioned on another side of the diaphragm and a second coil is mounted to the diaphragm. When fluid pressure is introduced into the pressure chamber, the diaphragm deflects, and the magnitude of current required to generate a recentering magnetic force which causes the diaphragm to be recentered constitutes a measure of the fluid pressure. Since the recentering magnetic force is substantially unaffected by temperature, the fluid pressure measurement obtained is substantially independent of temperature.

摘要： An array ultrasonic transducer precursor includes a body of piezoelectric material with a dielectric substrate bonded to a surface of the body. Circuit elements supported on the dielectric substrate include, in an active region, physically parallel signal conductors arranged in a pattern with spaces between adjacent ones of the conductors. Dicing saw cuts made in these spaces define individual circuit elements within the piezoelectric body. The circuit elements outside the active region include a set of resistive alignment elements in predetermined positions with reference to the pattern of signal conductors. The transducer precursor is mounted in a dicing saw fixture, and initial cuts made with the dicing saw remove portions of the resistive alignment elements. Locations of the initial cuts with reference to the resistive alignment elements are determined by measuring resistances of the resistive alignment elements after the initial cuts.
