摘要： A method for measuring a position, is performed by a vehicle assembly (VA) for alignment between a ground assembly (GA) and the VA. The method includes transmitting low frequency (LF) signals to initiate alignment with the GA and estimating a position of a vehicle using at least one sensor mounted on the vehicle. Information regarding the estimated position of the vehicle is provided to the GA and information regarding a position of the vehicle measured by LF receive antennas of the GA and an acceleration flag calculated by the GA is received. Accordingly, a transmission strength of the LF signals transmitted by the VA is adjusted based on the information regarding the position of the vehicle measured by the LF receive antennas and the acceleration flag.

摘要： A method for detecting a phase shift in an output signal of an inductive position sensor by calculating the phase spectrum of the position signal based on a Fast Fourier Transformation of the position signal and comparing the calculated phase spectrums over time to detect changes in the phase spectrums.

摘要： A method for determining the angular position of a shaft of a motor vehicle. The method includes calculating the mean angular resolution; calculating the time at which the cosine signal passes through zero; using the time at which the sine signal passes through zero and the mean angular resolution; determining the measured angle at the calculated time at which the cosine signal passes through zero; calculating the amplitude of the second harmonic of the measured angle signa;, calculating a second-harmonic error from the calculated amplitude of the second harmonic; and calculating a compensated angle representing the corrected angular position of the shaft from the real-time measured angle and from the calculated second-harmonic error.

摘要： A system for distinguishing target metal objects from each other in close proximity to each other. The method includes transmitting a first sinusoid signal via a first transmit coil to a first receive coil in close proximity to the first transmit coil; transmitting a second sinusoidal signal at a second frequency and amplitude different from the first frequency and amplitude to a second receive coil arranged in close proximity to the second transmit coil and in close proximity to the first receive coil such that received signals in the first and second receive coils include first and second frequency signals from the other of the first and second transmit coils. The received signals are separated via frequency domain multiplexing. The signals are compared to detect a presence of the target having a signal magnitude different from the first received signal and the received second signal and a known reference point.

摘要： A transmitting element for generating a magnetic field for tracking of an object includes a first spiral trace that extends from a first outer origin inward to a central origin in a first direction. A second spiral trace can extend from the central origin outward to a second outer origin in the first direction. The second spiral trace can extend from the central origin to the second outer origin in the first direction. The first spiral trace and the second spiral trace can be physically connected at the central origin to form the fluorolucent magnetic transmitting element and at least a portion of the first spiral trace overlaps at least a portion of the second spiral trace.

摘要： A coordinate measuring machine for measuring coordinates or properties of a workpiece includes an extended stylus. The extended stylus includes an extension element and a connection element. The extension element includes a carrier portion mounted at the connection element so as to be rotatable about an axis of rotation. The extension element includes, on a side remote from the connection element, a shaft portion that is aligned so as to deviate from the axis of rotation. The coordinate measuring machine includes a measurement head to which the extended stylus is attached. The measurement head is configured to measure deflections of the stylus resulting from contacts of the extended stylus to the workpiece.

摘要： A magnetic sensing tool (“MST”) uses differentials in induced voltage to detect the approximate location of a ferric target tool within surface pressure control equipment associated with a wellhead. The MST comprises a transmitter coil and two receiver coils configured such that a voltage generated in the transmitter coil induces a baseline voltage, and a baseline voltage differential, in the receiver coils when no target tool is present. A target tool passing axially through the MST will disrupt the magnetic fields inducing the voltages, such that variations in the voltage differential can be used to detect the approximate location of the target tool. The MST can be deployed alone or in series depending on the requirements of detection of the target tool.

摘要： This invention is Motion Recognition Clothing™ which measures the motion and/or configuration of a person's body using an energy-conducting mesh with a plurality of energy pathways. Energy input components direct energy into the pathways at a first set of locations. Energy sensors measure energy flow through the energy pathways from a second set of locations. As the person's body moves, the mesh stretches, elongates, and/or twists, which changes the flows of energy through pathways. These changes are then analyzed to estimate the motion and/or configuration of the person's body.
