Abstract: The present invention provides a pump assembly having an intake, an outtake, and a rotor rotatably mounted to a shaft. A propeller is fixedly mounted to the upstream portion of the rotor and is rotatable upon actuation of the rotor. A passageway is disposed on the rotor so as to provide a path for fluids to cool the shaft. The pump assembly includes chamber and a pipe. The chamber is disposed within the housing and is located downstream the intake and is in communication with the passageway. The pipe interconnects the chamber with the outtake. An impeller is fixedly mounted to the rotor opposite the propeller and draws air bubbles from the passageway into the chamber.

Abstract: In one embodiment, a method for determining a blow-by gas species concentration may include calculating one-dimensional engine performance data with a one-dimensional engine performance model. The one-dimensional engine performance data may be based at least in part upon an engine operating condition. The one-dimensional engine performance data may be transformed, automatically with a processor executing a two-dimensional ring dynamics model, into piston ring motion data. The two-dimensional ring dynamics model simulates geometrical changes to a piston-ring pack flow path. The blow-by gas species concentration may be determined with a network model including the one-dimensional engine performance model and a two-dimensional ring pack model. The two-dimensional ring pack model simulates species concentration change in the piston-ring pack flow path. The blow-by gas species concentration may be determined using the engine operating condition and the piston ring motion data.

Abstract: The invention concerns monolithic foam sleeves that comprises titanium or titanium alloy foam having a porosity of 50 to 85% and possess a proximal end, a distal end, an interior wall that defines an interior channel and extends from the proximal end to the distal end; and a terraced outer surface that tapers such that said sleeve is widest at the distal end and most narrow at the proximal end.

Abstract: A method for evaluating a sheet comprising the steps of casting a sheet and automatically determining characteristics relating to at least one of thickness or shape of the sheet during or immediately after the casting step. The method includes automatically determining chemical composition of the sheet. The method further includes receiving an order for the sheet and retrieving, from a database, specifications based upon the order. Finally, the method includes automatically comparing the determined characteristics to the retrieved specifications to determine the suitability of the sheet for use with the order.

Abstract: A cleat is provided, including a head and a shank connected to the head. The shank has a pair of opposing planar faces and a pair of opposing short edges, a wide portion and a point. The edges are provided with at least one serration fixed relative to the wide portion.

Abstract: A reusable orthopaedic instrument includes a reusable orthopedic trial having a first outer surface and a second outer surface that is opposite the first outer surface. The second outer surface includes a plurality of sidewalls extending outwardly therefrom to form a cavity. A drain hole is formed in the second outer surface at a location within the cavity. The drain hole extends through the reusable orthopaedic trial from the second outer surface to the first outer surface. Further, the second outer surface slopes downwardly from the plurality of sidewalls toward the drain hole.

Abstract: An annular device for the temperature control of a pump is provided. That device is in fluid communication with the radiator coolant system of a vehicle, and the engine-warmed coolant flows through the annular device to warm the pump and thaw ice buildup. The device is removable and can be added on to an existing pump without any redesign of the existing pump housing.

Abstract: A fastener driving tool is provided, including a housing substantially enclosing a power source including a reciprocating piston with a driver blade. A nosepiece is associated with the housing and is configured for receiving the driver blade and for sequentially receiving fasteners for engagement with the driver blade for driving into a workpiece. A magazine is configured for retaining a supply of the fasteners and for sequentially feeding the fasteners to the nosepiece, the magazine storing a plurality of elongate strips of the fasteners, and being configured for rotating about a longitudinal axis of the magazine for providing access of fasteners in each fastener strip to the nosepiece.

Abstract: A laser source assembly for providing an assembly output beam includes a first emitter, a second emitter, and a third emitter. The first emitter emits a first beam along a first beam axis that is substantially parallel to and spaced apart from an assembly axis. The second emitter emits a second beam along a second beam axis that is substantially parallel to and spaced apart from the assembly axis. The third emitter emits a third beam along a third beam axis that is substantially parallel to and spaced apart from the assembly axis. The first beam axis, the second beam axis and the third beam axis are positioned spaced apart about and substantially equidistant from the assembly axis.

Abstract: A rehabilitation system that combines robotics and interactive gaming to facilitate performance of task-specific, repetitive, upper extremity/hand motor tasks, to enable individuals undergoing rehabilitation to improve the performance of coordinated movements of the forearm and hand is disclosed. More specifically, the rehabilitation system includes a two degree-of-freedom (DOF) robotic, upper limb rehabilitation system and interactive gaming hardware that is coupled to a computer, to provide a virtual reality-like environment.

Abstract: A pre-molded or moldable shaft grip includes a pre-configured or moldable section disposed within a substantially circular outer grip layer. A pre-configured or moldable section substantially conforms to a player's grip, facilitating consistent finger placement. The pre-configured section may comprise the shaft, a separate section, or multiple sections of varying durometer. The moldable section may include a layer of moldable material, or a cavity disposed between the outer grip layer and the shaft containing a moldable substance. Overall grip durometer can be adjusted by varying the pressure within the cavity.

Abstract: A cover and method of covering a sterilizable medical container are described. The cover is used to cover a sterilizable medical container wrapped in at least one sheet of a wrapping material. The cover has a body including an upper member configured to hold the wrapping material against an upper portion of the container and a lower member configured to hold the wrapping material against a lower portion of the container. The body can be assembled about the wrapped container to hold the wrapping material about the container. At least one handle extends from the body which can be held by a user to move the covered wrapped container.
