An X-ray fluoroscopic imaging apparatus includes a table, an imaging system including an X-ray source and a detector, and an operation panel unit including a plurality of operation input units. The plurality of operation input units include an emergency stop unit and a stop state release unit. The emergency stop unit and the stop state release unit are provided separately from each other at different positions.

A transmission shifter includes a base defining P, R, N, D gear positions; four electrical dome switches associated with each of the P, R, N, D gear positions, and analog and digital circuits operably connected to the electrical switches, respectively, and associated with the P, R, N, D gear positions. The dome switches are arranged in different patterns in each of the different gear positions, and in combination with pushbutton actuators operate with different actuator motions and with different closure distances and forces to cause reliable ad confirmed intentional actuation, including redundancy. The switches are operably connected to analog and digital circuits, which provides additional functional advantage, reliability, and certainty of intentional operation.

An electronic push button for a motor vehicle door handle, including an activation pattern supported by a membrane that is flexible in the direction of an electric switch carried by a printed circuit board, the activation pattern defining an activation surface that is pressed by an operator's finger in order to push the activation pattern in the direction of the electric switch. The activation pattern is made up of a set of studs that extend parallel to one another away from the electric switch, with the majority of the studs being spaced apart from one another, the set of studs discontinuously delimiting an outer contour of the activation surface of the electronic push button.

What is presented is a key module (120) for a keyboard. The key module (120) comprises a guide (230) for guiding a movement of the key module (120) upon actuation, at least one spring element (240) for providing a reset force upon actuation of the key module (120), a support element (250) for supporting the guide (230) and a switch unit. The switch unit comprises a housing (270) and a contact device (280) at least partially arranged in the housing (270) for establishing electric contact upon actuation of the key module (120). The contact device (280) comprises a fixed contact piece with a first contact and a contactor with a first spring clip carrying a second contact and/or a second spring clip for producing an actuation sound and/or at least one actuation portion. The contactor is integrally formed.

Systems and methods for a hack-proof security keyboard are described. In some embodiments, a keyboard module may include a first circuit configured to detect activation of a plurality of keys and a second circuit configured to detect activation of a subset of the plurality of keys, where the second circuit overlies the first circuit. In other embodiments, a method may include detecting an electrical signal received from a secondary membrane of a keyboard, where the keyboard includes a primary membrane configured to detect individual activation of any of a plurality of keys, and where the secondary membrane is configured to output the electrical signal in response to concurrent activation of a subset of the plurality of keys. The method may also include performing a selected action in response to the detection.
