Patent number: 9671257Abstract: An arrangement measures coordinates of a workpiece and/or machines the workpiece. The arrangement has a first part and a second part that can be moved relative to the first part. The relative mobility of the first and second parts is specified in addition to a possible mobility of a probe that is optionally additionally fixed to the arrangement. The mobility of the probe is specified by a deflection of the probe from a neutral position during a mechanical probing of the workpiece for the purpose of measuring the coordinates. A measuring body is arranged on the first or second part, and at least one sensor is arranged on the other part, i.e. on the second or first part. The sensor generates a measurement signal corresponding to a position of the measuring body and thus corresponding to the relative position of the first and second part.Type: GrantFiled: July 8, 2011Date of Patent: June 6, 2017Assignee: Carl Zeiss Industrielle Messtechnik GmbHInventors: Tobias Held, Rainer Sagemueller, Dominik Seitz, Tobias Woletz

Patent number: 9618541Abstract: A magnetometer that senses low level currents flowing in a conductor or wire includes two cores with excitation windings on each core that are connected in series but which are wound in opposite orientations. A periodic alternating current drives the windings. Since the windings are in series but oppositely wound, the current flowing through the windings will produce equal but opposite flux flows in the two cores. A sensing winding is wound around both cores to provide flux profiles. A digital processor analyzes a quiescent flux profile, which is generated when no sense current is flowing through the dual cores, and distorted flux profiles when sense currents are flowing through the dual cores to measure a sense current flowing through the dual cores.Type: GrantFiled: April 20, 2016Date of Patent: April 11, 2017Assignee: NEILSEN-KULJIAN, INC.Inventors: Huy D.

Patent number: 9618583Abstract: A method detects faults during a steady state of an operation of an induction motor. The method measures, in a time domain, a signal of a current powering the induction motor with a fundamental frequency and determines, in a frequency domain, a set of frequencies with non-zero amplitudes, such that a reconstructed signal formed by the set of frequencies with non-zero amplitudes approximates the signal measured in the time domain. The determining includes a compressive sensing via searching within a subband including the fundamental frequency of the signal subject to condition of a sparsity of the signal in the frequency domain. The method detects a fault in the induction motor if the set of frequencies includes a fault frequency different from the fundamental frequency.Type: GrantFiled: March 10, 2015Date of Patent: April 11, 2017Assignee: Mitsubishi Electric Research Laboratories, IncInventor: Dehong Liu
