Abstract: An apparatus for controlling the angular direction of energy emitted from a plurality of energy delivery devices. The apparatus includes a plurality of rods, each rod mechanically coupled to one of the energy delivery devices, to a stationary plate, and to a moveable plate. The stationary plate includes holes that are configured to receive a portion of a first rotatable joint that is mechanically coupled to each rod. The moveable plate includes holes that are configured to receive a portion of a second rotatable joint, the second rotatable joint slidingly engaging a portion of the respective rod. The angle of each rod changes when the moveable plate is moved in any direction with respect to the stationary plate. Changing the rod angle changes the angular direction of the energy emitted from the energy delivery devices such that the energy passes through an intended focal position.

Abstract: A convertible patient support apparatus includes a patient support bed and a removable patient contact disposed in a hole in the patient support bed. The hole is defined by a support frame. A static membrane is attached to the support frame. One of a plurality of removable patient contacts can be removably attached to the support frame to convert the convertible patient support apparatus based on the patient and/or therapy.

Abstract: The invention relates to liquid dispensing and concerns a pipette comprising at least one aspiration channel with a piston. At the lower end of the aspiration channel there is an extension channel (3) and at its end a pipette tip mounting piece (4) onto which a pipette tip (5) is attached. On the pipette tip mounting piece there is a surrounding groove (17) and in the groove a sealing ring (18). The width of the groove in the axial direction is at least 1.1 times the thickness of the sealing ring in the axial direction. When the mounting piece is pushed into the pipette tip, the inner wall of the tip can move the sealing ring upwards in the groove. The construction can provide a reliable sealing despite of inherent dimension differences between different tips and mounting pieces.
