Abstract: Technologies and techniques for operating of a touch-sensitive display device of a vehicle. A processor display generates content on the touch-sensitive display device, wherein the content includes assigned elements configured to function in a display mode and an operating mode, depending on a user's presence in at least one of a first position and a second position of the vehicle. A sensing apparatus detects an approach by a user toward the touch-sensitive display device. The processor identifies that the user is in the second position relative to the display device, and, based on the identifying, changes an operating state of the display device to change at least one display mode element of the display content assigned to the second position from display mode to operating mode.

Abstract: A dental syringe employs a single thumb or finger operated control member mounted on the syringe for regulating the flow of air or water or spray. The single control moves axially and vertically with respect to the syringe. Axial movement either forward or rearward from a rest position, initiates and controls the quantity of flow of air or water. Vertical movement of the control member initiates the flow of both air and water to produce a spray.

Abstract: A foot controller for dental instruments having a pair of foot pedals which are depressed to initiate and control the rate of flow of a utility service, there being a single, variable output generator with the controller which can be operated by either the independent or simultaneous operation of the foot pedals.
