Abstract: A lost motion engine valve actuation system and method of actuating an engine valve are disclosed. The system may comprise a valve train element, a pivoting lever, a control piston, and a hydraulic circuit. The pivoting lever may include a first end for contacting the control piston, a second end for transmitting motion to a valve stem and a means for contacting a valve train element. The amount of lost motion provided by the system may be selected by varying the position of the control piston relative to the pivoting lever. Variation of the control piston position may be carried out by placing the control piston in hydraulic communication with a control trigger valve and one or more accumulators. Actuation of the trigger valve releases hydraulic fluid allowing for adjustment of the control piston position. Means for limiting valve seating velocity, filling the hydraulic circuit upon engine start up, and mechanically locking the control piston/lever for a fixed level of valve actuation are also disclosed.

Abstract: An oral hygiene device for use by infants, toddlers and small children as an effective tool for soothing and strengthening the gums and, when the new teeth begin to grow in, as an implement employed to keep the teeth clean and maintain both the gums and the teeth in a healthy condition, comprising a handle member, which is symmetrically oriented about a longitudinal axis, a head member, a nodule support surface and a plurality of nodules of varying heights and thicknesses supported by and extending from the nodule support surface, and a flange member mounted at the interface of the handle member and the head member. The head member and the nodule support surface are oriented longitudinally in a direction generally in alignment with the longitudinal axis of the handle member.
