Title: A controller for a portable touchscreen device
Filed: 2012-06-11
Abstract: A controller 11 for a portable touchscreen device 1 comprises a casing 13 having means 15, 17 to retain the device and a viewing aperture 19 through which most of the screen 3 of the device may be viewed. The controller further comprises multiple control buttons 21-37 adjacent to the viewing aperture but remote from the screen, and multiple control pads 39-49 positioned where they can be in contact with a peripheral portion of the screen. A coupling rod 61 located between each control button and its corresponding control pad is used to translate actuation of the control button into actuation of the control pad. The coupling rod normally provides an electrical disconnect between the button and the pad until the button is operated, at which point a conductive path between the button and the pad is created. This allows the control buttons to be located away from the screen so that they do not impede the view of the user, whilst allowing for maximum control function.

Patent DE-3169082-D1 (DE)
Title: Short-circuit protection device for a direct current actuator
Inventor: BRAJDER ANTONIO DIPL ING
IPC: H02P7/29
Filed: 1981-10-27
Granted: 1985-03-28
Abstract: A short-circuit protection device for a DC control element has at least one transistor which is addressed by timing pulses obtained by comparison of a triangular voltage with a control voltage. Each such transistor is provided with a separate overcurrent protection device which, after a short circuit, blocks the associated transistor until the beginning of a new switching-on pulse. The control voltage assumes values which are above the maximum value of the triangular voltage. In the event of a short circuit, the transistor concerned is switched off very fast, but is switched on again by the next succeeding switching-on pulse and a determination is made as to whether the short circuit is still present. If the control voltage rises to values which are above the maximum value of the triangular voltage because the actual value of the load current deviates heavily from the reference value due to the disconnection of the transistors, the transistors remain switched off until the DC control element is restored to operation by external intervention.

Title: Articulated portable trolley, designed to facilitate changing the wheels of trucks, coaches, tractors and similar vehicles
Inventor: PALMIERI PIERINO
IPC: B60B29/00
Filed: 1984-04-28
Granted: 1987-12-10
Abstract: The invention in question concerns an articulated portable trolley designed to facilitate changing the wheels of trucks, coaches, tractors and similar vehicles. The trolley, which is inserted under the wheel to be changed after it has been raised from the ground, can be adjusted according to the size of the wheel and raised to bring two arms with rollers into contact with the tire, which is supported, in this way, during dismantling. After having unscrewed the bolts, the trolley enables the wheel to be changed to be removed and lowered to the ground without effort. The new wheel to be mounted is then placed on the two lowered arms of the trolley and is, in this way, easily raised to the height of the hub and brought close to it. One of the two rollers may be made to rotate to make the wheel turn slowly to align the holes on the rim with the corresponding connections on the hub. The trolley is adjustable so as to be adaptable to wheels of differing sizes and can be dismantled in such a way as to be contained in a small case.
