    Abstract: A method and system of counting coulombs drawn from a power source by a load. A reference current source regulates the current drawn by the load at any given time to be either zero or a predetermined fixed amount. A comparator controls a time the switch is closed and open. When the switch is closed, coulombs are allowed to be drawn from the power source, and prevented to be drawn when the switch is open. An oscillator generates a clock signal during the time the switch is closed. A counter counts the number of clock cycles from the clock signal during the time the switch is closed. The count is provided as a signal at a second output of the coulomb counter.

  • Patent number: 9255976
    Abstract: In a current detection device for detecting current in a busbar, a reduction in device size may be realized by employing a small magnetic core. The prevention or reduction of excessive heat generation by the busbar, the facilitation of the attachment task, and a reduction in the amount of space required for the attachment task may also be realized. The folded-back busbar is U-shaped with a bar-shaped penetration portion that passes through a hole portion of a magnetic core, two bar-shaped extension portions, and two flat plate-shaped penetration portions. The width of each terminal portion is larger than the widths of the penetration portion and the extension portions. An insulating casing supports the magnetic core, a Hall element, and the folded-back busbar in a fixed positional relationship, with the two terminal portions being exposed to the outside.

  • Patent number: 9192311
    Abstract: A pulse wave detection device that includes a piezoelectric transducer acquiring the velocity pulse wave of a test subject and an information processing unit that processes the acquired velocity pulse wave and selectively detects regular velocity pulse wave data. The information processing unit acquires a differential waveform, extracts the extreme value of the velocity pulse wave, calculates the area value of a domain surrounded by the differential waveform and a reference line, compares the previous value and the current value of the extreme value with each other with respect to the velocity pulse waves chronologically adjacent to each other when the area value is greater than or equal to a predetermined value, and determines that the two velocity pulse waves are regular velocity pulse wave data when a difference between the two extreme values is less than or equal to a predetermined value.

  • Patent number: 9157814
    Abstract: Systems and methods for perturbation analysis of harmonic oscillations in the time domain according to several embodiments can include a time domain switching sensor and a resonator for imposing a first oscillation and a second oscillation on the sensor. The first and second oscillations can have the same amplitude A and period P, but can have a known phase shift. The sensor can use a time interval, which can be defined by the time between when the sensor passes a reference point due to motion caused by the first oscillation and when the sensor passes the same reference point, but due to motion caused by the second oscillation. With this configuration an improved accuracy of measurement for the system can be realized.

  • Patent number: 9052343
    Abstract: An apparatus and method make use of a single shunt and two or more instrumentation amplifiers, switchably measuring voltages at the shunt. This permits current measurement. At times each instrumentation amplifier has its input shorted, which permits zeroing out many sources of offset in the signal path of that amplifier. Dynamic range is several orders of magnitude better than known current measurement approaches, permitting coulometry.

  • Publication number: 20150137792
    Abstract: The invention relates to a power consumption monitoring apparatus (11) for monitoring the power consumed in a network (1) of electrical devices (3, 4, 5; 6, 7, 8). An electrical parameter measuring unit measures an overall electrical parameter of the network over time,a group signature providing unit provides group signatures, wherein each group signature is indicative of an electrical parameter of a certain group (9; 10) of electrical devices over time, and a disaggregation unit disaggregates the measured overall electrical parameter over time for determining the power consumption of the individual groups of electrical devices depending on the provided group signatures. This allows disaggregating the overall electrical parameter, without providing for each group an individual measuring unit, thereby reducing the required hardware and the time needed for installing and maintaining the power consumption monitoring apparatus.
