A control wheel includes a casing, a wheel ring, a first magnetic element, a pivotal shaft and a second magnetic element. The casing includes an accommodation structure and a concave structure. The accommodation structure includes a base. The wheel ring is disposed within the accommodation structure. The wheel ring is exposed outside through the accommodation structure and the concave structure. The pivotal shaft is disposed within the wheel ring and connected with the base of the accommodation structure. The wheel ring is rotatable relative to the pivotal shaft. The first magnetic element is disposed within the wheel ring. The second magnetic element is disposed within the base of the accommodation structure. The first magnetic element of the wheel ring and the second magnetic element are magnetically attracted by each other. Consequently, a rotating speed of the wheel ring is decreased.

An electronic device includes an enclosure and a keyboard positioned within the enclosure. The keyboard includes a substrate and a key mechanism. The key mechanism includes a keycap support mechanism, a keycap supported by the keycap support mechanism and movable relative to the substrate, a ferromagnetic component attached to the keycap support mechanism, and a selectively magnetizable magnet. The selectively magnetizable magnet system may include a magnetizable material and a coil configured to selectively magnetize and demagnetize the magnetizable material. The key mechanism may include a collapsible dome biasing the keycap toward the extended position.

The invention relates to an actuator device for change of state of an electronic-control apparatus for underwater use and a system for underwater use comprising the combination of a said actuator device with an electronic-control apparatus for underwater use. The actuator device for change of state of an electronic-control apparatus for underwater use comprises a main body designed to be associated in a stable way with at least part of said apparatus. A peculiarity of the invention is that it comprises, associated with the main body, magnetic-field generator means that interface, in the operating position of the actuator device, with reed-technology sensor means of said apparatus for sending electrical information to means for management and control of the apparatus that are designed to change the state, in particular the state of supply of the apparatus, said management and control means being electrically associated with a supply circuit of the apparatus, which comprises at least one power-supply battery, for the possible opening or closing of the circuit.

A capacitance detection device has: a first capacitor disposed in the path between a first node connected to a detection electrode and a second node; a second capacitor disposed in the path between the first node and the ground; a third capacitor disposed in the path between the first node and a third node connected to a shield electrode placed in proximity to the detection electrode; an alternating-current voltage output circuit that outputs a first alternating-current voltage to the third node; a first attenuation circuit that outputs a second alternating-current voltage resulting from attenuating the amplitude of the first alternating-current voltage; and a charge amplifier that supplies charge to the first capacitor through the second node and outputs a detection signal matching the supplied charge.

An underwater device may include a waterproof housing defining a dry cavity and having a nonferrous switch interface wall. The underwater device may include a rotary switch within the dry cavity and including a switch body, and a switch shaft extending outwardly from the switch body. The underwater device may include a first magnetic body within the dry cavity and coupled between the switch shaft and the nonferrous switch interface wall, and a second magnetic body external from the waterproof housing and adjacent the nonferrous switch interface wall in alignment with the first magnetic body so that rotation of the second magnetic body rotates the switch shaft. Each of the first magnetic body and the second magnetic body may include a permanent magnet.

A display device includes multiple gate lines, multiple source lines, multiple pixel electrodes provided respectively in regions defined by the multiple gate lines and the multiple source lines, and multiple common electrodes provided to face the multiple pixel electrodes and used for both image display and touch detection. A second drive circuit supplies a touch drive signal to each of the multiple common electrodes. A touch detection circuit performs detection of a touch by an object on the display device, based on a touch detection signal received from each of the multiple common electrodes. The display device includes multiple touch detection regions. Among the multiple common electrodes, multiple common electrodes are arranged in each of the touch detection regions. In the display system, touch detection is performed in part of the multiple touch detection regions, and touch detection is not performed in rest of the multiple touch detection regions.

A button deck includes a substrate and a two-part non-penetrating pushbutton assembly with an upper portion positioned on an upper surface of the substrate and a lower portion positioned on a lower surface of the substrate. The upper portion includes a button face positioned in a button frame that is coupled to the upper surface of the substrate. The button face is configured to be pressed to move within the button frame toward the upper surface of the substrate. The upper portion and the lower portion are configured to work together to provide a signal to an EGM that the button face has been pressed. The pushbutton assembly is non-penetrating because it does not provide any penetration points through the substrate of the button deck.

The resin molded article is molded by using an electrode sheet as an insert in a state where one surface of the electrode sheet is closely attached to an inner surface which serves as the inner side of the operation surface. The electrode sheet is formed by using, as a base material, a thermoplastic synthetic resin sheet which outputs an electrical signal according to the amount of change of electrostatic capacitance generated by a contact operation with respect to the operation surface. At least a whole or a part of the inner surface is formed in a three-dimensionally curved surface, and a passage is formed in the electrode sheet so as to allow a molten resin following in through a gate formed in a die which comes into contact with the other surface of the electrode sheet during molding to pass toward one surface side of the electrode sheet.
