Patent number: 9383876Abstract: A fingerprint sensing system comprises a sensor array with a plurality of sensing structures and read-out circuitry connectable to each of the sensing structures, and power supply circuitry arranged to provide to the read-out circuitry a substantially constant supply voltage being a difference between a high potential and a low potential. The fingerprint sensing system is configured in such a way that the low potential and the high potential are variable while substantially maintaining the supply voltage, and the read-out circuitry is connectable to each of the sensing structures in such a way that a variation in the low potential and the high potential while substantially maintaining the supply voltage results in a change of the charge carried by a sensing structure connected to the read-out circuitry. The change in charge is indicative of a capacitive coupling between the sensing structure and the finger.Type: GrantFiled: July 7, 2014Date of Patent: July 5, 2016Assignee: FINGERPRINT CARDS ABInventors: Frank Robert Riedijk, Hans Thornblom

Patent number: 9372204Abstract: The present invention provides a sensor body (1?) that can be used as part of a sensor assembly, optionally a capacitive sensor that is used to measure the clearance between the tip of a gas turbine engine blade and the surrounding casing. The sensor body includes a core layer (2) having an electrically conductive electrode layer (6). An outer insulating layer (4) substantially surrounds the core layer (2) and extends along a front part (8) of the sensor body to define a window layer (10) that provides a hermetic seal that excludes gas from any interface between the constituent layers of the sensor body. The core layer (2) and the outer insulating layer (4) are formed from the same electrically non-conducting ceramic material to avoid any problems with differential thermal expansion. The electrode layer (6) is embedded within a front part of the sensor body and extends between the core layer (2) and the window layer (10).Type: GrantFiled: July 25, 2011Date of Patent: June 21, 2016Assignee: Future Technology (Sensors) LtdInventor: Howard Elliott

Patent number: 9200529Abstract: A method for measuring and adjusting gaps between a rotor and a stator of a machine using a sensor is provided. The measuring is conducted when the rotor is operated at a rotational speed below a nominal rotational speed of the machine and without the machine being in operation. The adjusting of the gap is carried out as a function of at least one gap dimension of the gap. The sensor is not resistant to an operating temperature of the machine occurring in a region where the sensor is located. After completion of the measuring the machine is operated with the sensor.Type: GrantFiled: June 9, 2011Date of Patent: December 1, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Tobias Buchal, Björn Buchholz, Thomas Hille, Anna Kapustina, Mirko Milazar, Eric Schwerin

Publication number: 20150145531Abstract: A system for obtaining incremental and absolute displacement measurements using systems of electrodes that interact to form variable capacitors and systems that facilitate implementation of the method along with exemplary embodiments of these systems. The capacitors created by the disclosed method have known physical properties and corresponding known mathematical relationships. These laws are exploited in such a way by our method as to overcome inadequacies in existing systems and create superior systems. These superior systems improve upon the existing art by including economically and reliably made sensors based on the area varying principle which eliminate dead zone issues and increase accuracy through a reduction of the influence of gap variations on capacitive systems through the use of compensatory geometrical arrangements of multiple capacitive systems.Type: ApplicationFiled: November 26, 2013Publication date: May 28, 2015Inventor: Li LIN
