| 20130141085 | POSITION DETECTOR AND POSITION DETECTION METHOD - In a position detector having two sensors, a first sensor detects a position indicated by a first indicator by electromagnetic induction and a second sensor detects a position indicated by a second indicator by a detection method other than electromagnetic induction. The position detector reduces adverse effects of the transmission signal supplied to the second sensor on the electromagnetic induction position detection circuit. The position indication state of the first and second indicators is determined based on a signal output from the first sensor according to the position indication by the first indicator on the first sensor and a signal output from the second sensor according to the position indication by the second indicator on the second sensor. According to the determination results of the position indication state, the level of the transmission signal provided to the second sensor to detect the position indication by the second indicator is controlled. | 2013-06-06 |
| 20130141086 | ROTATION DETECTION DEVICE AND MANUFACTURING METHOD FOR THE SAME - A rotation detector component detects a rotational state of a rotor and sends a rotational detection signal. A signal transmission component is electrically connected with a lead frame of the rotation detector component to transmit the rotational detection signal to an external device. A body portion holds the rotation detector component and a part of the signal transmission component. The body portion is integrally molded of a first resin to cover a joint portion between the lead frame and the signal transmission component, the rotation detector component, and a part of the signal transmission component. A part of the rotation detector component forms an exposed portion exposed from the body portion. | 2013-06-06 |
| 20130141087 | MAGNETIC ENCODER HAVING THIN DETECTION SURFACE - A magnetic encoder including an object to be detected, a casing opposite to the object, a magnet and a magnetic sensor accommodated in the casing is provided. The casing of the magnetic encoder has an opposite wall opposite to the object. The opposite wall has a thickened portion and a thin portion integrally formed with the thickened portion. The thin portion has a smaller thickness than the thickened portion. The magnetic sensor is situated at the thin portion. | 2013-06-06 |
| 20130141088 | NON-INTRUSIVE MONITORING OF POWER AND OTHER PARAMETERS - Methods and apparatus for non-intrusive power monitoring and current measurement in a circuit breaker without modification of the breaker panel or the circuit breaker itself. In one example, an inductive pickup sensor senses current from the breaker face, an inductive link transmits power through a steel breaker panel door, and a passive balanced JFET modulator circuit modulates a carrier signal on the inductive link with information regarding the sensed current. A demodulated breaker current signal is available outside of the breaker panel door. The JFET modulator circuit does not require DC power to modulate the carrier signal with the information regarding the sensed current from the breaker. Such methods and apparatus may be interfaced with a spectral envelope load detection system that can monitor multiple loads from a central location. | 2013-06-06 |
| 20130141089 | Semiconductor GMI Magnetometer - A giant magneto-impedance (GMI) magnetometer is formed in a semiconductor wafer fabrication sequence, which significantly reduces the size and cost of the GMI magnetometer. The semiconductor wafer fabrication sequence forms a magnetic conductor, a non-magnetic conductor that is wrapped around the magnetic conductor as a coil, and non-magnetic conductors that touch the opposite ends of the magnetic conductor. | 2013-06-06 |
