Abstract: A unitary support for a flat panel video monitor includes a yoke that may be attached to a back side of the monitor in two or more different orientations, and handles extending from opposite side ends of the yoke. The handles may extend diagonally from the side ends of the yoke, imparting the support with a general appearance of the letter “W.” The yoke is also configured to be secured directly to a coupler at the end of an extension arm. A coupler attachment element of the yoke and a support attachment element of the coupler may have engagement features that are configured complementarily to each other to prevent undesired movement of the support relative to the coupler and the extension arm. The complementary engagement features may also enable attachment of the coupler to the support in two or more discrete orientations.

Abstract: An apparatus is provided that may be used to movably connect a device to a support. The apparatus may be a mechanical arm with multiple connections that allows the device to move into various positions and orientations. The connections may include a coupling attached to a connection assembly that movably secures the coupling to an elongated member. Each of the connection assemblies may provide a pivot point which allows rotation upon a sufficient force and provide a mechanism for removably securing a coupling at desired increments. The device may be an instrument or fixture for dental or medical use, such as an operating room light, a dental examination light, a liquid crystal display (LCD), a mirror, delivery head, etc. The support may be attached to a surface such as a ceiling or floor.

Abstract: A multiple position tool receptacle may be incorporated within a medical delivery unit, such as a dental unit head, allowing for positioning of a hand-held device in one of two or more seats. The receptacle may include a switching device operatively coupled in the receptacle to “activate” the medical delivery unit upon removal of a hand-held device from any one of the receptacle's seats. A method of providing multiple hand piece positioning in a “holster” is also provided.

Abstract: A hand-operated brake release may be incorporated within a medical delivery unit, such as a dental unit head, having an articulating apparatus allowing for improved ergonomic positioning of the delivery unit. The hand-operated brake release includes a sheath covering a switching element coupled to a handle in order to provide sealed brake releasing sensitive to the user's touch or grasp. A method of operating a delivery unit mounted on an articulating arm is also provided.
