Title: Temperature control system for a bathing unit
Inventor: LAFLAMME BENOIT
IPC: A61H33/00
Filed: 2005-01-11
Abstract: A temperature control system for a bathing unit that includes a water holding receptacle and a heating module. The temperature control system comprises a plurality of actuators associated to the heating module and a temperature regulation device in communication with the actuators. The plurality of actuators are adapted for acquiring a first set of actuation patterns for causing the heating module to acquire a non-heating state and a second set of actuation patterns for causing the heating module to acquire a heating state. The temperature regulation device is operative for controlling the plurality of actuators to cause the heating module to acquire either one of the heating state or the non-heating state and for selecting a configuration from the first set of actuation patterns for causing the heating module to acquire the non-heating state.    Alternatively, the temperature control system includes a solid state device associated with the heating module.

Title: A knee joint prosthesis
Inventor: FARRAR RICHARD
IPC: A61F2/30
Filed: 2004-02-09
Abstract: A knee joint prosthesis which comprises a tibial component (4, 6) and a femoral component (2). The femoral component has condyles (14, 16) which act against the tibial component, directly or indirectly, during flexing of the knee. A cam (20) on the femoral component acts against a post (26) on the tibial component at high flex angles. The surface of the post which is contacted by the cam at high flex angles is convex when the post viewed generally perpendicular to the tibial bone contact and bearing surfaces, and the femoral bearing surface which is provided by the cam, where it contacts the convex surface of the post at high flex angles, is locally concave (32) when viewed along the surface of the post which contacts the cam so that the area of contact between the post and the cam is greater at high flex angles than at lower flex angles.

Abstract: A convertible anchor (H) for friable walls (W) comprises a fixture (12) for holding an article to a wall (W, M) and an anchoring mechanism (10) extending from the fixture (12). The anchoring mechanism (10) is adapted when rotated to engagingly extend into a friable wall (W) for securing the fixture (12) to the wall (W). The fixture (12) is selectively separable via frangible connection elements (14, 24) from the anchoring mechanism (10) for allowing the fixture (12) to be used alone with an appropriate fastener (S) suitable for installing the fixture (12) to a rigid structure (M), such as wooden components. The anchoring mechanism (10) can take different forms as long as it is can be mounted to a friable wall (W). Typically, a space (26) is defined between the fixture (12) and a proximal end (34) of the anchoring mechanism (10) with this space (26) being bridged by the frangible connection elements (14, 24). The fixture (12) defines an opening (16) adapted to be engaged by a screwdriver bit (B) for mounting the ancnor (H) to the wall (W, M). The method calls for determining the nature of the vertical support to which the anchor (H) is to be mounted and then, for a friable wall (W), installing the anchor (H) thereto using the anchoring mechanism (10); or, for a more solid vertical support (M) such a wood, separating the fixture (12) from the anchoring mechanism (10) and installing the fixture (12) to the solid vertical support (M) via an appropriate fastener (S).

Abstract: A two speed transmission system particularly for marine use includes a first clutch for connecting an input shaft to a co-axial output shaft, a lay shaft typically parallel to the input and output shafts, a first gear train for connecting the input shaft to the lay shaft for driving the same via the input shaft, and a second gear train connecting the lay shaft to the output shaft.  The first clutch connects the input shaft to the output shaft; and a second clutch connects the input shaft to the output shaft via the lay shaft giving a gear ratio other than one to one. The gear trains are selected to provide a higher gearing i.e. faster spinning of the lay shaft when the second clutch is engaged. A control system receives inputs from various sensors including clutch pressure sensors, sensors measuring the speed of the input shaft and output shafts respectively and sensors providing information relating to the position of gears in the gear trains and controls the first and second clutches. Control valves and electro-hydraulic solenoids may be used to provide controlled clutch slip for docking and other functions where very low speeds of the order of a few knots may be desired. The control system may also be used to control the solenoid to allow slipping of the clutch when initiating movement of the watercraft to avoid the problem of "clunking" as the boat is put into, or taken out of, gear.
