A rotary switch device for a vehicle includes a rotary dial module including a plurality of sensors, a material configured to react to a magnetic force, and a base module that generates a magnetic force greater than or equal to a threshold value to enable the rotary dial module to be attached to the base module and transmits detection results from the plurality of sensors included in the rotary dial module to an electronic device inside the vehicle when the rotary dial module is attached to the base module.

The present disclosure provides a touch panel assembly and an electronic device. The touch panel assembly includes a touch panel, a touch switch, and a transmission assembly. The touch panel receives a touch operation from a user. The touch switch is positioned below the touch panel and located at a center position of the touch panel. The transmission assembly drives the touch panel to ascend and descend along a vertical direction synchronously and across an entire touch surface, and the touch panel activates the touch switch while descending. When subject to a given force, any touch areas of the touch panel can be pressed down, the touch panel stably moves synchronously and across its entire touch surface, so as to increase product stability. The touch panel assembly can achieve technical effects of a uniform touch feedback and the touch panel's stable movement, and so as to effectively improve user experiences.

A touch panel includes a first sheet and a second sheet that are disposed opposing each other. A first conductive path and a second conductive path are formed facing each other on main surfaces of the first sheet and the second sheet, respectively. The second conductive path is spaced apart from the first conductive path when viewed in the normal direction of the first sheet. On the main surface of the second sheet, pressure-detecting conductive paths electrically connected to the second conductive path are arranged. The pressure-detecting conductive paths intersect the first conductive path as viewed in the normal direction. Structures are disposed on a second sheet main surface not opposing the first sheet, and cause flexing of the corresponding pressure-detecting conductive path to contact the first conductive path when pressed down.

A control panel for a vehicle. The control panel includes a decorative layer and a control assembly. The decorative layer has a visible face and a rear face opposite to the visible face. The control assembly has a front face and a rear face opposite to the front face. The front face of the control assembly faces the rear face of the decorative layer. The control assembly is fixed to the decorative layer and includes a support film, a pressure sensor and a light-emitting diode. The pressure sensor and the light-emitting diode are printed on the support film.

The invention relates to a capacitive sensor system comprising sensor electronics and a sensor portion (1) consisting of a synthetic construction material which comprises a sensor electrode (3; 22) and to a method for the production and use of said sensor system.

A system includes a piezoelectric capacitor assembly and signal processing circuitry coupled to the piezoelectric capacitor assembly. The piezoelectric capacitor assembly includes a piezoelectric member and piezoelectric capacitors located at respective lateral positions along the piezoelectric member. Each piezoelectric capacitor includes: (1) a respective portion of the piezoelectric member, (2) a first electrode, and (3) a second electrode. The first and second electrodes are positioned on opposite side of the piezoelectric member. The piezoelectric capacitors include piezoelectric force-measuring elements (PFEs). The PFEs are configured to output voltage signals between the respective first electrode and the respective second electrode in accordance with a time-varying strain at the respective portion of the piezoelectric member between the respective first electrode and the respective second electrode resulting from a low-frequency mechanical deformation. The signal processing circuitry is configured to read at least some of the PFE voltage signals.

The described technology includes an apparatus comprising a proximity sensor pad and booster element located between an antenna and the proximity sensor pad, wherein voltage level of the booster element at least ten percent higher than voltage level of the proximity sensor pad. Implementations of the booster element may be made of metal or metal-ink and may have U-shape or L-shape.

An optical detection sensor functions as a proximity detection sensor that includes an optical system and a selectively transmissive structure. Electromagnetic radiation such as laser light can be emitted through a transmissive portion of the selectively transmissive structure. A reflected beam can be detected to determine the presence of an object. The sensor is formed by encapsulating the transmissive structure in a first encapsulant body and encapsulating the optical system in a second encapsulant body. The first and second encapsulant bodies are then joined together. In a wafer scale assembling the structure resulting from the joined encapsulant bodies is diced to form optical detection sensors.

Key assemblies are disclosed herein that are retractable and/or that present a variable key assembly depression force to a user. In one example, one or more key assemblies may be provided that each employ one or more electro-permanent magnets (EPMs) together with permanent magnet and/or magnetically permeable (e.g., ferromagnetic) key assembly components to control key retraction and extension, and/or to control peak depression force (e.g., typing force) required to depress and displace a key assembly from an extended position to a lower position that causes the key assembly to produce a digital or analog output signal.

Systems and methods are disclosed that may be implemented to indicate real time availability of individual key assemblies for user input to an information handling system. In one embodiment, the disclosed systems and methods may be implemented to retract an individual key assembly of a user input device (e.g., such as keyboard matrix, game controller, game pad, computer mouse, etc.) when the key assembly is, or becomes, unavailable for input to a user application (e.g., such as a computer game) that is executing on a host programmable integrated circuit (e.g., such as host CPU) of an information handling system. Such a retracted key assembly may then be extended when it becomes available for input to the user application.
