Abstract: A dental prosthesis has a gum sealing rim that snugly contacts the patient's gum. The cavity formed within the gum sealing rim is accessed by through holes via which a pressurized cleaning fluid may be injected into the cavity. The cleaning fluid swirls around and washes of bacteria and deposits. Through a number of cleaning fluid drains, the cleaning fluid exits again the cavity. An additional drain blocker may be configured such that it blocks the cleaning fluid drains while it is clamped by the patient between the teeth. The resulting pressure build up in the cavity causes the cleaning fluid to squeeze out and clean the sealing interface between the gum sealing rim and the patient's gum.

Abstract: A base for fixing the safety seating system in a passenger car has an external guiding member that more than equatorially encompasses an internal guiding member for a direct spherical guiding of a removable seated newly born infant. The infant is seated with respect to the geometrical pivoting center and an overall mass axis of the rotating portions such that neck bending and head whip lashing are minimized during a vehicle crash. The encompassing spherical and direct guiding provides for a free impact aligned reorientation of the seated infant unimpeded by adjacent elements of the car that are eventually forced into contact during crash. The direct spherical guiding provides also for a lightweight construction of the rotating portions with low momentum of inertia and consequently high responsiveness of the safety seating system.

Abstract: A support pin matrix features a number of support pins densely two dimensionally arrayed and individually springily suspended such that a patient's body or body portions may be bedded directly on the support pins. The pins are preferably pressurized by a fluid pressure system for highly balanced contact pressure irrespective the individual pins' load deflection. A control system may provide a pin retraction wave of the support pins. A body resting surface accessing device may be moved across the support pin matrix and beneath a bedded patient in conjunction with the pin retraction wave. The resting surface accessing device may be configured for cleaning, drying, inspecting, irradiating, and/or massaging the body resting surface and/or for maintaining the body support pin matrix. A body carrying net may be retracted and raised in between the body support pins to lift the patient off the support pin matrix.

Abstract: Simple and rigid attachment of a child seat to a vehicle seat that is not degraded by the seat's cushioning is provided by a head rest fixture and two latch anchor fixtures combined by an operationally rigid frame structure. The frame structure has horizontal and vertical telescopically adjustable and lockable features to fit the system to varying dimensions of vehicle seats, head rests and child seat latch anchors. The child seat may be attached to the system via an object connecting structure that is combined with the frame structure via an in between damping element. The damping element opposes vehicle vibration eventually induced via the latch anchors on the operationally rigid frame from reaching the child seat.

Abstract: Optical fibers are inserted and bonded in a two dimensional array of feedthroughs provided by an insert having a top plate, a bottom plate and a sandwiched spacer plate. Top and bottom plate feature funnel shaped hole sections that capture the approaching fiber end during its insertion. The funnel sections terminate in narrow hole sections that tightly hold the inserted fiber ends. Having top and bottom plate spaced apart provides for high angular precision of the bonded fiber ends with minimal fabrication effort of the insert. Optical fibers may be combined in linear arrays and simultaneously inserted significantly reducing assembly efforts. The insert is attached to a fiber housing and hermetically sealed within an external housing, which features a glass plate to provide beam propagation to and from the fiber ends. An optical gel fills the gap between the insert's output face and the glass plate.

Abstract: A rotatable vacuum chamber receives an optical connector having an output face on which an optical gel is applied substantially without entrapped air. Opposite the output face is placed a gel dispenser with its opened nozzle pointing towards the output face. Uncured gel components contained in the dispenser are outgased prior to application of the gel on the output face while a vacuum is maintained in the chamber. Outgasing takes place at a first chamber orientation with the nozzle pointing upwards through which the outgasing air ventilates. The gel is applied at a second chamber orientation where the output face is horizontal and upwards pointing. Immediately following the gel application, the vacuum is unmade to prevent cooking of the mixed and uncured gel. A glass plate is then pressed against the applied fluid gel.

Abstract: The present invention is directed towards a focus-position compensator for reducing focus variations on a microlens array. The focus-position compensator comprises a plurality of tiles that are affixed to a structure disposed between the lenslets of the microlens array and the target of the collimated light from the lenslets. Each tile refractive index and tile thickness is chosen to obtain a tile focus-position correction that will apply to a region of the microlens array.
