20110025299 | DUAL-RANGE MEASUREMENT OF ELECTRICAL CURRENT - An electrical current measurement system. A sense impedance and a composite amplifier are in electrical communication and together define a trans-impedance circuit that presents a frequency-compensated impedance lower than the sense impedance to an input electrical current to be measured. A sense amplifier in electrical communication with the sense impedance provides an output indicative of a magnitude of the input electrical current. A current bypass circuit may parallel the trans-impedance circuit and bypass the input electrical current around the trans-impedance circuit when the current reaches a predefined magnitude. The system may be combined with another current sensor to form a dual-range current measurement instrument. | 02-03-2011 |
20110109300 | MULTI-RANGE ELECTRICAL CURRENT MEASUREMENT - An electrical current measurement system. A first low-range current gauge receives a current to be measured and provides a first intermediate value indicative of the amplitude of the current up to a first maximum current. A second low-range current gauge receives any portion of the current having a magnitude that exceeds the first maximum current and provides a second preliminary value indicative of the amplitude of the portion of the current having a magnitude that exceeds the first maximum current up to a second maximum current. An arithmetic unit or a digital processor receives the first intermediate value and the second preliminary value and provides a second intermediate value indicative of the amplitude of the current. A full-range current gauge may also be provided. A selector or the digital processor selects one of the values for display or other output. | 05-12-2011 |
20140152335 | CONTINUOUS BROKEN SENSE LEAD DETECTION SYSTEM - Disclosed is a continuous broken sense lead detection system (“CBSLDS”) for use with a Kelvin-connected device under test (“DUT”), a power source, and detection system stimulus configured to provide a periodic stimulus voltage. The CBSLDS is configured to detect a discontinuity in a first sense lead, second sense lead, or both, that are in signal communication with the DUT. The CBSLDS includes a first transformer, second transformer, first DC-blocker, second DC-blocker, first detection module, and second detection module. | 06-05-2014 |

20100327850 | METHODS AND APPARATUS FOR ACQUIRING MEASUREMENTS AND PERFORMING AN AUTO-ZERO PROCESS USING A MULTI-RANGE MEASUREMENT APPARATUS - In one embodiment, a measurement apparatus has an input stage, an output stage and a multiplexer. The input stage has a signal input, a plurality of measurement range outputs, and a plurality of selectable gain stages, with each of the selectable gain stages being coupled between the signal input and a respective one of the measurement range outputs. The output stage has a measurement acquisition path between an analog measurement input and a digital measurement output. The measurement acquisition path includes an analog-to-digital converter. The multiplexer has i) a plurality of data inputs, at least two of which are coupled to respective ones of the plurality of measurement range outputs, and at least one of which is a reference input configured to receive a signal to which signals appearing at the measurement range outputs are commonly referenced, ii) a data output coupled to the analog measurement input of the output stage, and iii) a control input. | 12-30-2010 |

20080201503 | Communications System for Implementation of Synchronous, Multichannel, Galvanically Isolated Instrumentation Devices - An apparatus and method for synchronous communications using a serial data stream employs a housing with a controller and a back plane. The housing accepts one or more modules for interconnection with the back plane. The back plane distributes power to the modules and provides a communication link from the controller to each module. Each communication link includes a data out line, a data in line and a clock line, where each clock line is derived from one clock source. | 08-21-2008 |

20140198549 | ENERGY DISSIPATING DEVICE FOR DC POWER SUPPLIES - An energy dissipating device configured to connect to a power supply and to dissipate excess energy from a direct current (DC) rail in response to a change in power supply settings or operating characteristics. The energy dissipating device is connected to the DC rail, which conducts current generated by an AC/DC converter to at least one DC/DC converter. When power demand to the DC/DC converter is reduced, the DC/DC converter generates a supplemental current surge on the DC rail. A rail current monitor monitors the current level on the DC rail and generates the DC rail power signal indicative of the supplemental current surge level generated by the at least one DC/DC converter. The supplemental surge current is used to control dissipative elements connected across the DC rail to modulate a current sink path across the DC rail to dissipate the excess energy from the DC rail. | 07-17-2014 |
