Patent number: 8606539Abstract: A radar (peripheral object observation device) repeatedly observes a relative position of an object relative to the moving object, which is located in the vicinity of a moving object. A stationary object identification unit (stationary object determination unit) determines whether or not the object the relative positions of which have been observed by the radar is still. A road approximate curve temporary computation unit (object correlation unit) determines a plurality of the relative positions of an identical object observed by the radar from among the relative positions observed by the radar. A road approximate curve main computation unit (approximate curve computation unit) computes an approximate curve that approximates the configuration of a road on which the moving object is located, based on a result of the determination by the stationary object identification unit and a result of the determination by the road approximate curve computation unit.Type: GrantFiled: February 3, 2011Date of Patent: December 10, 2013Assignee: Mitsubishi Electric CorporationInventors: Yuki Takabayashi, Takashi Matsuzaki, Hiroshi Kameda, Yasushi Obata

Publication number: 20130325386Abstract: A mobile electronic equipment includes a gyro sensor that detects an angular velocity, a first housing with the gyro sensor disposed therein, a second housing movably connected to the first housing, an angle formed between the respective housings being changed by movement of the first housing, and a control unit that calculates a change in an angle formed between the first housing and the second housing before and after the movement as a measured angle, based on output data of the gyro sensor. The control unit calculates a correction value for the output data of the gyro sensor based on the measured angle and a reference angle set in advance (see FIG. 1).Type: ApplicationFiled: February 17, 2012Publication date: December 5, 2013Applicant: NEC CASIO MOBILE COMMUNICATIONS, LTD.Inventor: Satoshi Takano

Patent number: 8594971Abstract: Systems, methods, and apparatus for performing deduced reckoning navigation without a constraint relationship between orientation of a sensor platform and a direction of travel of an object are described herein. A sensor fusion component can be configured to receive data from sensors of a sensor platform coupled to a pedestrian; and generate world coordinate information based on the data. Further, a gait recognition component can be configured to record one or more walking patterns of the pedestrian in a training database; and determine whether the world coordinate information is associated with a walking pattern of the one or more walking patterns. Furthermore, a position estimation component can be configured to estimate a position of the pedestrian based on the world coordinate information if the world coordinate information is associated with the walking pattern, regardless of an orientation of the sensor platform with respect to the position of the pedestrian.Type: GrantFiled: September 22, 2010Date of Patent: November 26, 2013Assignee: Invensense, Inc.Inventors: William Kerry Keal, David Sachs, Shang-Hung Lin, Erik Anderson

Publication number: 20130311130Abstract: A sensor system includes a sensor and processing means adapted to process the signals from the sensor, and to provide a distance measurement or estimate from the sensor to a metallic object of interest, such as a turbine blade. The sensor, typically an eddy current sensor, provides a signal to which the processing means fits a curve, and parameters including pulse width and height are taken from the fitted curve and used in calculating the distance measurement or estimate. Look-up tables may be used to produce the measurement or estimate. Average values of the parameters may calculated to reduce random noise effects and may be subsequently used to produce correction factors to correct instantaneous measurements.Type: ApplicationFiled: February 13, 2012Publication date: November 21, 2013Applicants: The Secretary of State for Business Innovation and Skills, QINETIQ LIMITEDInventors: Thomas John Horton, Paul Antony Manning

Patent number: 8577627Abstract: A hydraulic operated system for testing cable under variable tensions and speeds with a lower input horsepower requirement. The system can include storage reels in series with multiple moveable sheaves. A moveable tensioning moveable sheave can be in series with the multiple moveable sheaves for receiving cable and for measuring load and speed of the cable using sensors. The system can include clutches and a clutch controller. The measured load and speed can be transmitted to a processor which can perform calculations and comparisons thereon, and can transmit related notifications to client devices through a network.Type: GrantFiled: September 21, 2010Date of Patent: November 5, 2013Assignee: Dynacon, Inc.Inventors: Joe R. Janac, James H. Stasny

Patent number: 8569986Abstract: A demagnetization detection device and a demagnetization detection method thereof are provided. The demagnetization detection device is for use in a power control unit which is electrically connected to a testing permanent magnet motor. The power control unit is electrically connected to a direct current power source. The demagnetization detection device is configured to detect a testing voltage value and a testing current value of the direct current power source, and to compute a testing power value of the direct current power source according to the testing voltage value and the testing current value. The demagnetization detection device determines the difference between the testing power value and a standard power value, and then determines whether the testing permanent magnet motor is in a demagnetization status according to the difference.Type: GrantFiled: September 27, 2011Date of Patent: October 29, 2013Assignee: Delta Electronics, Inc.Inventor: Jen Chih Tseng
