Abstract: An orthopaedic surgical instrument includes a patella trial and drill guide that may be used to both perform a surgical trial of the patellofemoral joint and guide the surgeon in drilling a number of anchor holes in the patella of the patient.

Abstract: A reconfigurable user interface for a modular patient monitor which selectively populates menus for operator selection based on the parameters which are available at any given time. Due to event processing, when a parameter module is added or removed from the system, the reconfigurable user interface is updated immediately to reflect the addition or subtraction of the associated parameter. A flash box in each menu provides shortcuts to the most likely menu option in response to asynchronous events such as alarms and the like. The flash box also assists the operator with the particular steps that must be followed to properly setup or operate a particular feature of the system. Since the menus are not modal, an operator may navigate the menus without making any selections or changing the state of the device.

Abstract: A cushioned helmet structure comprising a helmet shell and liner; and a multiplicity of flexible fins carried by the helmet and projecting generally inwardly relative to the liner to resiliently deflect in bending when receiving loading imposed by the user's head received within the helmet.

Abstract: A receptacle having a cover with a seal located between the cover and receptacle and flexible fins located on the interior of the receptacle and cover. The fins are deflected and the seal depressed in response to an article being squeezed between the cover and receptacle upon fastening the cover to the receptacle. External flexible finned protectors are provided for external corners and edges of an article.

Abstract: A universal holder for a cup that has a handle and a side wall, comprises:(a) a generally horizontal base to support a cup in a zone above the base,(b) an upright frame attached to the base,(c) a retainer attached to the frame and extending generally above the base to retain the cup wall, the retainer extending about that zone and forming a generally upright slot to guidably downwardly receive the cup handle,(d) and the frame attachable to a vehicle.

Abstract: A packaging medium comprises:(a) a flexible support wall, and(b) fins integral with that wall to project generally toward a structure to be packaged, to confine same during such packaging,(c) the fins being resiliently and yieldably deflectible to bend relative to the support wall in response to squeezing relatively toward the structure,(d) the fins extending in generally parallel planes and having terminal edges that define a positioning plane relative to which the fin planes are out of perpendicularity.

Abstract: A universal cup holder, comprising(a) a generally horizontal base to support a cup,(b) an upright frame attached to the base,(c) a retainer attached to the frame and extending generally horizontally above the base to retain the cup wall,(d) a resilient pusher element supported by the frame to engage the cup wall and urge the cup toward the retainer,(e) there being structure attached to the frame to attach the holder to a vehicle door.

Abstract: A rosary device on a wrist watch or clock has electrically energizable elements in a pattern, the elements having different characteristics corresponding to different rosary prayers.

Abstract: A special router for cutting an L-shaped groove in elongated frame members has an elongated cutter stem and an axis about which the stem is rotatable; the stem has substantially parallelogram cross sections in planes normal to that axis; and a cutter head is provided at the end of the stem and integral therewith, the head also having substantially prallelogram cross sections in planes normal to that axis. Further, the router head has generally outwardly convex outer surfaces and opposite flat sides intersecting said curved outer surfaces. The router is movable laterally to cut L-shaped grooves in the frame members, which are adapted to have their grooved ends joined by an L-shaped bracket receivable into the grooves to hold the members in L-shaped assembly.

Abstract: A container comprises a receptacle and a cover therefore, the receptacle having a bottom wall and the cover having a top wall, fins integral with at least one of such walls and projecting toward the other of such walls to engage an article placed within the container and between the walls when the cover is closed onto the receptacle, the fins being yieldably deflectible in response to squeezing of the article between the walls, and fastener structure associated with the receptacle and cover to hold the cover closed on the receptacle with the article squeezed and thereby positioned with the fins in deflected state.

Abstract: An artificial heart valve includes tapering flaps which are suspended to pivot between open and closed positions.

Abstract: A lock-up corner bracket for frame parts is characterized by:(a) the bracket having legs that extend in planes which define a corner angle,(b) the legs having terminal enlargements that are elongated in parallel directions of forward insertion of the legs relatively into recesses formed in said parts, for retaining said parts in assembled relation.

Abstract: Apparatus for receiving a tape cassette includes a sleeve, at least one flexible arm on the sleeve top wall, and a projection carried by each arm to cam against the cassette and to drop into a cassette reel opening to block rotation of the reel.
