Abstract: A detection unit has a fixed magnet, which is part of a magnetic circuit unit, and also has a movable magnet and a magnetic sensor, which are disposed below a cap. A fixed magnetic field component oriented toward a vibration direction acts on the magnetic sensor due to a leakage flux from the magnetic circuit unit. A movable magnetic field component acts from the movable magnet on the magnetic sensor in a direction crossing the fixed magnetic field component. A change in the angle of a detection magnetic field component, which is a combined vector formed from the magnetic field components in two directions, is detected by the magnetic sensor. According to the output in this detection, the operational position of the movable magnet is measured.

Abstract: A switching device includes a first knob to receive a pressing operation in a first direction; a pressing detection switch to be pressed upon transmission of an operating force of the pressing operation; a decorative member to decorate a periphery of the first knob, that includes an engaged portion; and a holder to engage and hold the decorative member, that includes an engaging portion to engage the engaged portion. In response to the pressing operation by a first stroke amount, by the operating force transmitted to the pressing detection switch without transmitted to the engaged portion, the pressing detection switch is pressed. In response to the pressing operation by a second stroke amount greater than the first stroke amount, by the operating force applied to the first knob being transmitted to the engaged portion, the engaged portion elastically deforms, and engagement of the engaging/engaged portions is released.

Abstract: An input device is characterized in that in a first stroke region in which an operation panel is pushed during a touch operation, a first reaction force that occurs by pushing the operation panel is generated by the first elastic portion. In a second stroke region including a stroke longer than in the first stroke region and a stroke for performing a push operation, a second reaction force that occurs by pushing the operation panel is a resultant force generated by a first elastic portion and the push switch. In the vicinity of a boundary between the first stroke region and the second stroke region, the amount of change in the first reaction force with respect to a stroke length is less than the amount of change in the second reaction force with respect to a stroke length.

Abstract: In order to provide a receiver capable of accurately determining a phase difference of I/Q signals, a receiver includes a section detector configured to detect a section between a rising and a falling of a phase based on the rising and the falling of the phase represented by I/Q signals generated based on an advertisement packet transmitted from a transmitter, and a section setting unit configured to identify, within the section between the rising and the falling of the phase, a period in which a first variation amount of the phase is equal to or less than a first predetermined amount, and use the identified period as a section for detecting the phase of the I/Q signals. The section detector detects the rising when a first phase is smaller than a last phase among a plurality of phases acquired by sampling the phases.
