  • Patent number: 12098661
    Abstract: A control system for a cam phaser can include a cam phaser coupled to a cam shaft, the cam phaser to adjust a position of the cam shaft, an actuator in mechanical communication with the cam phaser, and a controller in electrical communication with the actuator, the controller including a processor and a memory. In one example, the processor is configured to calculate a first hysteresis position of the actuator with respect to a hysteresis band, determine if the actuator is within a first threshold distance of a first edge of the hysteresis band, and if the actuator is not within the first threshold distance of the first edge of the hysteresis band, command the actuator to displace across the hysteresis band.

  • Patent number: 8361162
    Abstract: This invention relates to an orthopaedic joint prosthesis implant kit (2). The implant kit comprises a stem component (4) of an orthopaedic joint prosthesis which is intended for articulation with a mating component of the joint. The stem component has a distal end (6) and a proximal end (8), and a neck part (10) at the proximal end, and is configured for fixation in a bone cavity-using bone cement material with the distal end within the cavity and the proximal end at the opening of the cavity, and with the neck part protruding from the cavity towards the mating component of the joint. The implant kit further comprises a positioning kit (18), at least one spacer (20, 22, 24) for location between the wall of the cavity and the stem component at its proximal end, and a delivery device (26).

  • Patent number: 6990197
    Abstract: An improved hands-free speaker telephone designed to provide high-quality sound in a relatively small instrument, while at the same time avoiding acoustic shock to a user pressing the device too closely to an ear. If a speakerphone is mistaken for an ordinary portable or cellular phone, or simply out of misguided habit, a user may intentionally or inadvertently press the speaker against an ear. This action may subject the ear to an overly-loud audio event if the speaker begins producing sound, as hands-free speakerphone speakers are typically set to a much higher volume than those of ordinary phones. The effect, which is sometimes referred to as ‘acoustic shock’, is worsened significantly where the user actually succeeds in sealing the phone around the ear, as commonly (and harmlessly) occurs with standard (personal) phones. To avoid this undesirable phenomenon, the hands-free speakerphone is provided with a seal-proof speaker configuration.

  • Patent number: 6254641
    Abstract: A pressurizer device (1) is provided with a body (6) in the form of a collar and a surrounding radially extending flexible flange (8). A prosthetic component to be disposed in a cemented bone cavity is inserted through the central opening (50) in the body (6). Pressure in the bone cement is maintained during insertion of the prosthetic component by the flange (8) being held down around the prosthetic component during insertion.

  • Patent number: 6205884
    Abstract: A handle assembly (1) has a handle body (4), an arm (8) and a trigger mechanism (6). The handle body (4) has a recess (18) for receiving an instrument to be held by the handle assembly (1). The arm (8) pivots in relation to the handle body (4) and the trigger mechanism (6) holds the arm (8) in two positions relative to the handle body (4). A third position enables the arm (8) to be detached from the handle body (4). In the first position, the arm (8) is locked adjacent the handle body (4) such that a projection (30) from the arm (8) engages the recess (18) in which a neck of an instrument being held can be inserted.
