摘要： Systems and methods for mitigating constraints associated with wireless power transmission in applications where the position and orientation of the desired magnetic field changes over time, for example, because the position and orientation of the receiver being powered changes over time or because different receivers having different positions and orientations are being powered at different times. In accordance with some embodiments, the system employs a plurality of wireless power transmitters in a defined space, each transmitter consisting of individual coils oriented orthogonally relative to each other. Using field interference amongst these individual coils as well as amongst the transmitters they form, one can actively control the wireless power field intensity and orientation at any given point in the defined space. This allows for methods to steer the power transmission towards a specific target at a specific angle.

摘要： Wearable apparatuses and methods for using reinforced neurofeedback for sports training are disclosed. Embodiments of such wearable apparatuses are configured to be worn at or near a user's joint to monitor the joint position. An embodiment may comprise a processor, a computer-readable medium, a sensor, an IO component, a battery, a timer, a signaling component, and a flexible printed circuit. The computer-readable medium of this embodiment may be configured to store at least one optimal range of joint position and/or a sequence of timed optimal ranges of joint positions for a specific sport. In this embodiment, the sensor continuously detects the joint position, and once the processor determines that the joint position falls outside the optimal range of joint position, it activates the signaling component to send a feedback signal so that the user may immediately make correction. Another embodiment is a disposable, biodegradable epidermal patch with a middle layer of balsa wood sandwiched between two protective layers or a protective sheath.

摘要： There are arranged a sensor magnet fixed to a rotary shaft and configured to generate a magnetic field for detecting a rotation angle, and a plurality of sensors arranged so as to be opposed to the sensor magnet and each configured to output a sine signal and a cosine signal in accordance with the magnetic field. First and second sensors are arranged on two radial lines different from each other, respectively, out of three radial lines dividing a circumference about the rotary shaft of the sensor magnet into six equal parts. An angle calculation unit is configured to carry out calculation so that 3n-th (n is a natural number) order harmonic components out of odd-order harmonic components of each of the sine signal and the cosine signal output by the first and second sensors cancel one another, to thereby calculate the rotation angle.

摘要： Embodiments relate to magnetic field angle sensors, including off-axis and on-axis sensors. In an embodiment, a magnetic field angle sensor comprises two sensor units, and each sensor unit comprises two sensor elements. The sensor units are spaced apart from one another and arranged proximate a magnet, wherein the two sensor elements of each sensor unit are responsive to the same magnetic field component induced by a magnet coupled to a shaft as the shaft rotates. In each sensor unit, a sum and a difference of the output signals of the two sensor elements can be calculated to determine a coarse estimation of a rotation angle, and a more refined estimation can be obtained by combining the coarse estimations of each sensor unit. In embodiment, the magnetic field angle sensor comprises a control unit or other circuitry to carry out this combining.

摘要： Sensor assemblies are described for measuring isotropic, anisotropic, or directionally dependent, characteristics of a subterranean formation. Sensor assemblies can include sensors deployed on a tool string. One or more of the sensors can be rotatable relative to the tool string. Rotating one or more sensors relative to the tool string can provide data about the subterranean formation at multiple points around the tool string.

摘要： The present invention relates to a double analysis of signals emitted by a rotational angle sensor. For this purpose, the signal emitted by the rotational angle sensor is processed in a first signal path with respect to a maximum angle quality of the angle signal to be calculated. A second signal path for processing the signal emitted by the rotational angle sensor is optimized to indicate a maximum diagnosability of errors.
