  • Patent number: 7373128
    Abstract: With respect to a first wireless transmit/receive unit (WTRU), at least one WTRU near the periphery of other cells is determined. Out of the at least one WTRU near the periphery, at least one WTRU nearby that WTRU is determined. The first WTRU codes are provided of the at least one nearby WTRU. A contribution of the at least one nearby WTRU is canceled from a received signal at a first WTRU, producing an interference canceled signal. Data of the first WTRU is detected from the interference canceled signal.

  • Patent number: 7242909
    Abstract: A location of a wireless transmit/receive unit (WTRU) is determined. A measurement is made by the WTRU. The measurement is sent to a base station. The sent measurement is combined with measurements sent by other WTRUs to estimate a measurement made for a longer duration than the sent measurement.

  • Patent number: 7221520
    Abstract: A video connection is established using cameras which are able to be remotely controlled by a distant viewer. A local radio link is established between a telephony device such as a cellular telephone or other wireless transmit/receive unit (WTRU). A distant viewer connected through a telephone link can use a video image screen to view the camera image and can use the telephone link to control the operation of the camera.

  • Patent number: 7164908
    Abstract: The invention provides for various cell condition measuring devices and methods. One aspect is a mobile wireless monitor. The mobile monitor takes channel quality information and location information for use in cell condition analysis. Another aspect is a fixed wireless monitor. The fixed monitor takes channel quality information and sends it to a monitored source. Another aspect is a method for analyzing cell channel conditions. A baseline of the channel conditions is generated and wireless monitors update the baseline. Another aspect is a method for base station site selection. A mobile wireless monitor is used to determine an optimum base station site.

  • Patent number: 6816442
    Abstract: A sports annunciation system is remotely controlled by players in unofficiated games. Players start and stop game timers by wireless communication to a base unit using a switching device on their person. The system audibly announces time-in, time-out, remaining time and key game events. The device simulates time control and announcements found in officiated games.

  • Patent number: 6449567
    Abstract: Briefly stated the motor speed monitor includes a method of determining a shaft speed of a motor by using an electrical signature of the motor. The method includes: (a) sensing an electrical current supplied to the motor to generate a current sensor output signal for at least one electrical phase of the motor; (b) demodulating the current sensor output signal for a predetermined time interval to obtain an instantaneous amplitude of the electrical current signal; (c) generating a frequency spectrum of the instantaneous current amplitude; (d) finding at least one spectral peak of the instantaneous current amplitude frequency spectrum within a predetermined shaft frequency sideband range; (e) estimating a shaft frequency from the at least one spectral peak and converting the shaft frequency to shaft speed.

  • Patent number: 5519300
    Abstract: A method for determining at least one operating parameter to determine the operating condition of a polyphase electric motor system comprises sensing the instantaneous current signal and the instantaneous voltage signal as a function of time for more than one electrical phase of the motor. The sensed current signals and the sensed voltage signals are both amplitude demodulated and phase demodulated to provide amplitude demodulated current and voltage signals as a function of time and phase demodulated current and voltage signals as a function of time. The resulting amplitude and phase demodulated signals are used to determine one or more of the following electrical parameters as a function of time: total real power, real power per phase, total reactive power, reactive power per phase, total apparent power, apparent power per phase, overall power factor, power factor per phase, electrical impedance per phase, and electrical balance.

  • Patent number: 5517585
    Abstract: A method of stably identifying and characterizing a transient contained in a sampled set of data, the data representing a physical event, where alignment of the sample points with the transient is typically arbitrary. The method includes the step of analyzing the first data set using a predefined mathematical operator to produce a second data set, detecting and isolating the discrete data pattern in the second data set, determining a location of the detected and isolated data pattern in the second data set, measuring a difference between the location of the detected and isolated data pattern and a predetermined location of the predefined mathematical operator, adjusting preselected parameters of the mathematical operator in accordance with the measured location difference such that the adjusted mathematical operator is aligned with the detected and isolated data pattern, and reanalyzing the first data set using the aligned mathematical operator.

  • Patent number: 5432436
    Abstract: A method is disclosed for approximating the stem thrust during the operation of a motor operated valve combination including a valve having a valve stem, a valve disk, a valve seat, and a motor operator having a motor drive means interconnecting the motor to the valve stem for movement of the valve stem disk toward and into engagement with the valve seat to close the valve and a control switch for deactivating the motor.

  • Patent number: 5012411
    Abstract: A portable, self-contained, microprocessor controlled apparatus for monitoring, storing and transmitting detected physiological information, including an input section for sequentially receiving analog signals corresponding to heart activity for as many as twelve different cardiac sensors. An input section is provided for receiving analog electrical signals corresponding to blood pressure from at least one sensor. An analog to digital converter is provided for converting the received analog signals to a series of digital pulses at a predetermined sampling rate and for receiving and storing the digital pulses in predetermined memory locations. A control section is provided for recalling the stored digital pulses from the memory and for receiving the recalled digital pulses and for transmitting them to a remote location over a communications system.
