摘要： A brake pedal device includes: a housing fixed to a vehicle; a brake pedal provided to be swingable about a predetermined axis with respect to the housing and to receive a depression operation of a driver; and at least three sensors that output signals according to an operation amount of the brake pedal. The at least three sensors include at least one magnetic sensor and at least two inductive sensors, for example. The at least two inductive sensors are spaced apart from each other such that a movement of a target metal of one inductive sensor is detected by a sensing coil of the one inductive sensor but a movement of a target metal of any other inductive sensors is not detected by the sensing coil of the one inductive sensor.

摘要： A sensor device to be attached to a drug delivery device includes an array of conducting elements each forming part of a respective resonant circuit and each operable to have a signal applied to it. The drug delivery device has a first movable element supporting a conductive region, which is configured to move along a path parallel to a longitudinal axis of the drug delivery device. When the sensor device is attached to the drug delivery device, the conducting elements are arranged such that each resonant circuit is operable to output a signal indicative of the proximity of the conductive region supported on the first moveable element to the respective conducting element of each resonant circuit. The sensor device includes circuitry to receive the signals output from the resonant circuit and, based on the received signals, determines information associated with a location along the path of the first movable element.

摘要： A position detecting system detects and responds to the movement of a target through a sensing domain area of a plane. The movement causes the amount of the target that lies within a sensing domain area to change. A portion of the target always lies within at least one of the sensing domain areas of the plane.

摘要： A stroke sensor system includes a tubular vehicle-body-side member, a tubular vehicle-wheel-side member, and a displacement obtainer. The tubular vehicle-body-side member is disposed at a vehicle body side. The tubular vehicle-wheel-side member is coupled to the vehicle-body-side member on a vehicle wheel side and movable in an axial direction of the vehicle-body-side member relative to the vehicle-body-side member. At least one of the members is a conductor. Another one of the members includes a coil. The displacement obtainer includes a capacitor electrically coupled to the coil and constituting an LC oscillation circuit that outputs an oscillation waveform when the members move relative to each other. The displacement obtainer digitizes the oscillation waveform to obtain a reshaped waveform, divides a frequency of the reshaped waveform by a frequency division ratio to obtain a frequency-divided waveform, and uses the frequency-divided waveform to obtain a displacement by which the members move relative to each other.

摘要： An induction type position measuring apparatus includes a scale and a sensor. The scale includes a track having a plurality of control patterns provided at equal intervals along a measurement reference line to control flow of an induced current, and a first edge portion and a second edge portion located on both sides of the measurement reference line. The sensor is provided to be capable of moving relatively to the scale along the measurement reference line to detect an induced current. The scale includes regulation patterns at least between the track and the first edge portion or between the track and the second edge portion to regulate a flow of an induced current.
