Abstract: Hip implant systems described herein can include a distal stem, a proximal body, and a fastener. In some embodiments, the distal stem can include a cavity configured to receive the fastener when a portion of the distal stem is positioned within the proximal body. In some embodiments, the distal stem can include a threaded exterior surface configured to mate with a fastener when a portion of the distal stem is positioned within the proximal body. In some embodiments, a distal end of the distal stem can include an anterior relief configured to conform to interior surface of a femoral canal of a patient.

Abstract: A flow sensor has a paddle assembly that is mounted to a housing by opposed pivot posts which extend from the paddle assembly between the paddle and the magnet. The housing has two pivot post clips that resiliently capture the pivot posts which are received in mounting holes in resilient clips A shroud surrounds the housing and positions a biasing magnet which repels the magnet on the paddle assembly. The shroud slides over the housing and provides a transverse passageway that is aligned with a passageway in the housing. An activation sensor positioned within a sleeve is positioned within the transverse passageway of the housing and passes through a transverse passageway in the shroud pinning the two subassemblies together.

Abstract: A turbine type flow meter has a four-vaned plastic torpedo-shaped turbine mounted by portions of the plastic turbine within a housing between first and second bearings. The turbine supports a pair of magnets of the Neodymium-Iron-Boron type which rotate with the turbine. An upstream portion of the housing incorporates a sensor cavity, which is sealed from a flow cavity containing the turbine. A connector and an attached printed circuit board with a Hall effect sensor is mounted within the sensor cavity closely spaced from the rotating magnets. The sensor housing is constructed from two parts. Each part of the housing incorporates mating structures that are designed for joining by spin welding.

Abstract: A vehicle door handle has a fixed part, a movable part and a sensor. The sensor is a magnet and a magnet-actuated switch. Movement of the movable part relative to the fixed part causes the magnet to activate the switch. A flux blocker is arranged between the magnet and the switch to prevent magnetic flux from the magnet actuating the switch. The flux blocker is arranged to expose the switch to magnetic flux when the movable part moves relative to the fixed part.

Abstract: A reed switch in a solid plastic body is positioned by a clip adjacent to a fluid container. A change in fluid level opposite the reed switch moves a magnet connected to a float, turning the reed switch on or off. Glass filled polyester is injected into a die which surrounds the reed switch supported on electrical plug blades. The reed switch has high stiffness leads positioned on the blades, and is oriented within the mold so the injected plastic flows along the glass tube of the reed switch, minimizing stresses on the reed switch, which could result in the reed switch becoming crack and/or broken. The molded plastic body incorporates an integrally formed clip arm that functions to position and hold the plastic body onto a larger structure. The magnet and float may move in a tube, may pivot, or slide along rails in response to a change in fluid level.

Abstract: A metering device has a magnet with ten poles which is driven to rotate by a gear connected to a source of rotation that is proportional to fluid flow, the passage of time, or other phenomenon. A reed switch is mounted so that rotation of the poles of the magnet, into and out of a position adjacent to the reed switch causes the reed switch to open and close as the magnet rotates. The opening and closing of the reed switch causes a step change in voltage applied to an electronic device which increments a counter. A second reed switch spaced from the rotating magnet sufficiently so that it remains normally open can act as a sensitive device for detecting the presence of extraneous magnetic fields that might interfere with the operation of the first reed switch.

Abstract: A bidirectional shock sensor has a housing mounted directly to a printed circuit board. The housing contains a switch or sensor embedded in the housing and is connected by leads to the circuit board. A pendulum sensing mass is suspended from two flexible pendulum arms. The arms come together where they are attached to the housing and constrain the mass to swing along an arc that lies in a plane. A magnet either forms the sensing mass or is mounted to the sensing mass. A reed switch or Giant Magneto-Restrictive (GMR) type sensor is encapsulated within the base of the housing. When a shock causes motion of the sensing mass and the magnet the motion is detected by the sensor or switch.
