An operation detection device for a key operation of a keyboard device includes a conductive unit configured to be disposed on each of keys, a substrate configured to be disposed facing each of the keys in a pressing direction of the keys. The substrate is provided with a sensor including at least first and second coils, the sensor being configured to be disposed spaced from one key so that at least one of the first or second coil outputs a signal corresponding to a distance between the one key and the respective sensor. The operation detection device includes a detection unit configured to detect a displacement of the one key in at least one of a yaw direction or a roll direction based on signals output from the first and second coils during a key pressing stroke of the one key.

A ring input device, and more particularly to variable rotational resistance mechanisms within the ring input device that modulate the rotational friction of a rotating outer band to improve the user experience, is disclosed. Because finger rings are often small and routinely worn, electronic finger rings can be employed as unobtrusive communication devices that are readily available to communicate wirelessly with other devices capable of receiving those communications. Ring input devices according to examples of the disclosure can modulate the rotational friction of its rotating outer band in accordance with an item (e.g., user interface or parameter) being manipulated by the band.

A push button switch assembly for a vehicle includes an elastic button that is moveable between a first unactuated position and a second actuated position. An actuator is disposed adjacent a plate and is pivotable between a first position and a second position. The actuator includes a magnetic element. When the elastic button is in the first unactuated position the magnetic element biases the actuator into the first position, and when the elastic button is moved to the second actuated position, a force applied to the elastic button is transmitted to the actuator such that the force overcomes the magnetic attraction and permits the actuator to pivot to the second position while providing a tactile haptic response. When the actuator is moved to the second position, a hall sensor senses a change in the magnetic field of the magnetic element.

A detection system is used in a musical keyboard instrument that includes a key, the displacement of which changes in accordance with a playing operation. The detection system includes a detectable portion configured to be disposed on the movable member and including a first coil; a signal generator including a second coil configured to be disposed spaced from the first coil and configured to, in a state where the second coil receives a supply of current: generate a magnetic field; and generate a detection signal with a level depending on a distance between the detectable portion and the second coil; and a magnetic body disposed on at least one of the movable member or the signal generator.

A push button switch assembly for a vehicle includes a housing having a plurality of walls that collectively define an inner space, and an elastic button that is moveable between a first unactuated position and a second unactuated position. A plate is positioned in the housing and an actuator is pivotable between a first position and a second position. The actuator includes a magnetic element. When the elastic button is in the first unactuated position, the magnetic element biases the actuator into the first position, and when the elastic button is moved to the section actuated position, a force applied to the elastic button is transmitted to the actuator to pivot the actuator to the second position.

Disclosed herein is an input device having adjustable input mechanisms. The input mechanisms of the input device may be dynamically adjusted based on one or more input characteristics associated with a user. Accordingly, the input device may be customized to fit a user's input preferences.

A control device includes a moving portion, a magnetic element coupled to the moving portion, at least one magnetic sensing circuit responsive to magnetic fields, and at least one magnetic flux pipe structure. The magnetic element may comprise alternating positive and negative sections configured to generate a magnetic field. The magnetic element may be any shape, such as circular, linear, etc. The magnetic sensing circuit may be radially offset from the magnetic element, and the magnetic flux pipe structure may be configured to conduct the magnetic field generated by the magnetic element towards the magnetic sensing circuit. The magnetic element may generate the magnetic field in a first plane, and the magnetic sensing may be responsive to magnetic fields in a second direction that is angularly offset from the first plane. The magnetic flux pipe structure may redirect the magnetic field towards the magnetic sensing circuit in the second direction.

A ring input device, and more particularly to pressure-sensitive input mechanisms within the ring input device that detect pressure to initiate an operation, is disclosed. Because finger rings are often small and routinely worn, electronic finger rings can be employed as unobtrusive communication devices that are readily available to communicate wirelessly with other devices capable of receiving those communications. Ring input devices according to examples of the disclosure can detect press inputs on its band to generate inputs that can then be wirelessly communicated to companion devices.

A latch assembly, including: at least one moveable component rotationally mounted to the latch assembly; a magnet secured to the at least one moveable component; a hall effect sensor remote from the magnet; and a metal trace operably coupled to the hall effect sensor and configured to be magnetized by the magnet as the at least one moveable component rotates.
