Patent number: 9404879Abstract: An apparatus for measuring electrical conductivity of liquid is disclosed. The present invention as disclosed accurately and consistently measures infinitesimal conductivity of liquid by applying a stable reference signal to a conductivity sensor controlled with a constant temperature, and by low-noise processing on an output signal from the conductivity sensor. More specifically, infinitesimal conductivity of liquid can be repeatedly and accurately measured and change in performance of the detection apparatus over time can be minimized, by minimizing temperature variations, unstability of a reference signal, and noise effects to ensure stablility of a baseline as a measurement reference of the conductivity and accuracy of conductivity measurements.Type: GrantFiled: May 20, 2013Date of Patent: August 2, 2016Inventor: Nam Tae Kim

Patent number: 9395410Abstract: Integrated circuit comprising a sensing unit that includes a sensing circuit, two conductors and a magnetic storage element. The sensing circuit monitors a voltage drop across the element when a current is passed between the conductors with the element in between. The voltage drop is pre-calibrated to indicate a change in conductivity in the element that is caused by an external magnetic field. Advantageously, this indication is usable particularly for assessing a possible data corruption in a magnetic memory circuit in the integrated circuit, due to stray and external magnetic fields. Methods of using the sensing unit are also proposed.Type: GrantFiled: June 6, 2011Date of Patent: July 19, 2016Assignee: III HOLDINGS 1, LLCInventor: Krishnakumar Mani

Patent number: 9395171Abstract: A method and system for determining a distance from a probe to an object includes generating a first electric field by applying a first signal across a first pair of electrodes aligned along a first axis and generating a second electric field by applying a second signal across a second pair of electrodes aligned along a second axis substantially perpendicular to the first axis. After generating the signals, a first change in the first signal due to the object interacting with the first electric field and a second change in the second signal due to the object interacting with the second electric field is concurrently detected. A distance of the object from the first and second pair of electrodes can be calculated based on a ratio of the first and second changes.Type: GrantFiled: November 5, 2012Date of Patent: July 19, 2016Assignee: SIEMENS ENERGY, INC.Inventor: Nikolai R.

Patent number: 9366548Abstract: The embodiments described herein include systems with a variable reluctance sensor (VRS) interface and methods of their operation that may reduce the probability of erroneous transitions in a resulting generated detect signal. As such, the VRS interface can improve the accuracy of position and/or motion determinations, and thus can improve the performance of a wide variety of devices that use variable reluctance sensors. In one embodiment the VRS interface uses a comparator with hysteresis to generate a trailing edge signal. In another embodiment the VRS interface uses bias voltages to reduce the probability of erroneous transitions in a trailing edge signal. In either case the VRS interface can prevent erroneous transitions in the detect signal and thus may improve the performance and accuracy of the system.Type: GrantFiled: October 3, 2013Date of Patent: June 14, 2016Assignee: FREESCALE SEMICONDUCTOR, INC.Inventors: William E.
