  • Patent number: 9793679
    Abstract: A distributed Raman amplifier comprises a loss-measuring device that measures losses in an optical fiber transmission line; a signal processing circuit that compares the measured losses to a threshold, below which a pumping light source is permitted to pump the transmission line; a control circuit responsive to a control signal from the signal processing circuit for controlling operation of the pumping light source; and a spool of fiber configurable to be optically coupled between the pumping light source and optical point-loss sources in the transmission line when the losses are above the threshold. The spool of fiber has a fiber of sufficient length to offset aggregated losses, which prevents the distributed Raman amplifier from shutting down while also allowing the distributed Raman amplifier to achieve entitled gain by pumping the fiber in the spool.

  • Patent number: 9207129
    Abstract: A preexisting voltage across a sensor is latched to a storage capacitor prior to any excitation current being applied to the sensor. Once the excitation current is applied, the voltage on the storage capacitor is directly subtracted from a differential voltage across the sensor. The subtraction is done before a measurement is converted to a digital value and passed to a transmitter. The subtraction is performed in hardware, and a time required to sample and hold the preexisting voltage across the storage capacitor is within a settling time used for collecting any sensor measurements.

  • Patent number: 7009491
    Abstract: A dual purpose key fob has manipulable keys for, in a normal mode, locking and unlocking a vehicle and keys for opening a vehicle trunk and activating a panic alarm and, in a training mode, for sending code signals to tire pressure sensors to tell the sensors what tire they are in, e.g., after wheel rotation, so that the sensors subsequently can transmit the proper location signals to the vehicle's ECM along with the pressure signals.

  • Patent number: 6988043
    Abstract: A method compensates for measurement errors of an external transformer coupled between an electricity meter and one or more power lines. The method includes a first step of obtaining at least one error rating for the external transformer. The method also includes the step of storing data representative of the at least one error rating in a memory within the meter. At some point the electricity meter is coupled to the external transformer. The method further includes the step of employing the meter to obtain at least one electricity consumption measurement value, the at least one electricity consumption value including either a sampled current value or a sampled voltage value. Finally, the method includes the step of causing the meter to adjust the at least one electricity consumption measurement value using at least a portion of the stored data.

  • Patent number: 6781521
    Abstract: An electromagnetic borehole telemetry system providing improved signal to noise ratio. Adaptive filters use noise channels as references to remove noise from the signal channel. Multiple noise channels are coupled to series connected adaptive filters for removing each noise source from the signal channel. The order of noise removal is selected to remove the most significant first.

  • Publication number: 20040074323
    Abstract: A measuring device incorporating a substrate with sensors that measure the processing conditions that a wafer may undergo during manufacturing. The substrate can be inserted into a processing chamber by a robot head and the measuring device can transmit the conditions in real time or store the conditions for subsequent analysis. Sensitive electronic components of the device can be distanced or isolated from the most deleterious processing conditions in order increase the accuracy, operating range, and reliability of the device.

  • Patent number: 6664900
    Abstract: A programmable transducer device that includes a signal source (e.g., a sensor) and a transducer output to output a transducer output signal and to receive a control signal from an external control unit. The control signal is superposed on the transducer output signal, and is detected at the transducer output from a resultant superposition signal by a detector circuit. The transducer output signal and the control signal may co-exist on the transducer output. Advantageously, providing a programmable transducer device that is actuated by control signals conducted through the transducer output and does not need to be switched over to a special receiving state, ensures the uninterrupted transmission of transducer output signals even while the control signals are received by the programmable transducer device. In addition, no additional signal path is required for programming.

  • Patent number: 6647351
    Abstract: The position of the inner surface of a hollow metal workpiece on a machine tool is detected by connecting an operating member of the machine, preferably a tool, to a first terminal of an electric power source; connecting the inner surface to a second terminal of the power source; moving the operating member gradually towards the inner surface to detect the emission of a signal generated by an emitting device interposed between one of the terminals and the inner surface, and corresponding to a condition in which initial contact is established between the operating member and the inner surface; and determining the position of the operating member at the instant the signal is emitted.

    Abstract: An apparatus for use with a digital field sensor comprises a digital communication circuit. The digital communication circuit is operative to output a digital signal indicative of calibration information for the digital field sensor. A processor is connected in operational communication to the digital communication circuit. The processor is operative to receive a value communicated to the processor by the digital field sensor. The processor is also operative to calculate calibration information based on the value and to provide the calibration information to the digital communication circuit.

  • Publication number: 20020070877
    Abstract: A measuring transducer with a sensor for converting a detected measured value into a sensor signal. The sensor signal is processed in a signal processing device to form a measuring signal that is transmitted to a central location via a data interface. The data interface is also used as a conduit for signals to parameterize the measuring transducer. The measuring transducer includes a device that provides a simulated measuring signal that can be transmitted to the central location on request via the data interface instead of the detected measured value. Further, a function can be performed on the simulated measuring signal before it is transmitted or a sequence of simulated measuring values can be transmitted corresponding to particular operating conditions.
