An information display system for a switching device having a handle includes a cover for the switching device and a faceplate. The cover includes an opening sized to allow passage of the handle. The faceplate is configured to carry information about the switching device. The faceplate is rotatable with respect to the cover to change an orientation of the information.

A power supply system includes: a power supply terminal, for receiving first power from an external power source or outputting second power to a load; at least one battery, for receiving and storing first power in a charging mode, and outputting second power to the power supply terminal in a discharging mode; a charger, enabled in the charging mode for charging the battery by first power; a switch, turned on in the discharging mode for transmitting second power to the power supply terminal; a current detection circuit, for detecting a current of the power supply terminal to determine whether the power supply system is operated in the charging or discharging mode. The current detection circuit controls the charger to be enabled in the charging mode and disabled in the discharging mode, and controls the switch to be turned on in the discharging mode and turned off in the charging mode.

An electronic watch may include a tactile switch and/or one or more sensors for detecting rotational and translational inputs. The watch may include a display configured to produce graphical outputs that may change in response to rotational inputs, translational inputs, and/or touch inputs received at the display. The watch include a crown positioned along an exterior of the watch enclosure and a shaft coupled to the crown and extending into the enclosure. The tactile switch and/or the one or more sensors may be used to detect rotational and/or translational inputs provided at the crown.

Presently provided is a keyboard, key stabilizer mechanism, and method. At least one of the keys on the keyboard has a stabilizer mechanism with spaced apart bases. A stem is supported on each of the bases with perpendicularly disposed hinges. A wire is disposed to cooperate with a hinge supporting each of the stems.

An attachment for conventional weapon mounted lasers that provides a larger and more convenient and ergonomic interface of actuating the laser. The laser attachment is molded or formed as a single piece from a pliable rubber or similar material and has a switch cover and a pair of opposed side straps. The side straps are dimensioned and configured to wrap around the laser and affix to the bottom of the laser. The switch cover is dimensioned and configured to seat and nest over the activation switch on the top of the laser. The switch cover has interior (bottom) and exterior (top) surfaces that substantially mirror the profile to the activation switch; however, the switch cover has a diameter larger than the activation switch. Depressing any area of the switch cover actuates the laser. The larger surface area of the switch cover provides improved acquisition for the user without increasing size or footprint of the laser.

The control panel and display of a cart-borne ultrasound system are support by a lift which can be controlled to allow the control panel and display to be raised, lowered, and rotated. The lift has a first pivot elbow mounted to the ultrasound system cart and a second pivot elbow on which the control panel and display are mounted. A four-bar linkage is coupled between the pivot elbows which enables to control panel and display to be raised and lowered while maintaining the inclination of the control panel. The pivot elbows allow the control panel and display to be turned and rotated. A pair of hydraulic struts are mounted to the four-bar linkage to support the weight of the control panel and display. When a control button on the handle of the control panel is depressed the control panel and display can be freely raised, lowered and rotated. When the control button is released the pivot elbows and four-bar linkages are locked in their current positions.
