Abstract: A weightlifting barbell includes a steel shaft and sleeves constructed of engineered plastic (e.g., POM, Teflon®, Nylon, UHMW, and the like). The engineered-plastic sleeve is relatively light weight and provides impact strength suitable for executing weightlifting exercises.

Abstract: A cardiac rhythm management (CRM) device can extract ventilation information from thoracic impedance or other information, and adjust a delivery rate of the CRM therapy. A tidal volume of a patient is measured and used to adjust a ventilation rate response factor. The measured tidal volume can optionally be adjusted using a ventilation rate dependent adjustment factor. The ventilation rate response factor can also be adjusted using a maximum voluntary ventilation (MVV), an age predicted maximum heart rate, a resting heart rate, and a resting ventilation determined for the patient. In various examples, a global ventilation sensor rate response factor (for a population) can be programmed into the CRM device, and automatically tailored to be appropriate for a particular patient.

Abstract: Individual participants in a multi-participant collaborative computing application may be sent intermittent updates of actions taken by other participants. These updates need not be sent to a participant's device until the participant has interacted with a specified object in the application. The participant's device may then be sent an update including object interactions of the other participants occurring since the participant's previous object interaction. The update may be used to periodically inform the participant of the actions taken by the other participants during the period between the participant's interactions.

Abstract: The present invention relates to a magnetic actuation method according to which a magnetized mobile (4) is directed by means of at least one magnetic element (2, 2a, 2b) placed opposite said magnetized mobile, characterized in that the preferred direction (or easy axis) of magnetization is made to turn at every point of said element by applying at least one mechanical constraint to said magnetic element(s) (2, 2, 2b), causing anisotropy within said element and thus moving the magnetized mobile in a preferred linear direction or causing the same to rotate.

Abstract: In one embodiment, a three-dimensional object is rendered on a two-dimensional display screen by associating a three-dimensional mesh with an image of the object, generating a vector-based texture map that defines a surface area of the object, and rendering the vector-based texture map on the display screen.

Abstract: Apparatus and method for connecting tubular members in a wellbore. A host tubular member has annular members mounted within a receiving section to provide regions of differing resistance to the radial load. When a portion of a second tubular member is expanded radially outwardly within the receiving section a joint is formed between the members. Embodiments of host tubular members are described including recesses for the portion to form protrusions within, collapsible rings, channels and valves to expel fluid from the interface between the members and gripper elements and sealing elements to improve the joint.

Abstract: Apparatus and method for connecting tubular members in a wellbore. A host tubular member has reinforcing annular members mounted thereon to provide regions of differing resistance to the radial load. When the host tubular member is expanded radially outwardly, within a second tubular member, each weaker region starts expanding first and seals the host tubular member against the second tubular member prior to the stronger region. Embodiments of host tubular members are described including members of progressive resistance, split rings, gripper elements and sealing elements.

Abstract: An apparatus and method for providing a tubular connection in the form of a liner tieback connection or a liner hanger in a slim hole well as found in deep wells. When installing the casing sections, a first casing section having a profiled surface distinct from a surface of an adjacent casing section is provided. A liner is run into the first casing section and a part of a portion is radially expanded to morph against the inner surface of the first casing section at the profiled surface and form a sealed joint. Various arrangements of profiled surfaces are provided. The liner may also have a profiled surface. By adapting the casing section to receive the liner directly, a slim hole well construction is achieved.

Abstract: A rate-adaptive pacemaker and a method for its operation in which the response factor for a minute ventilation sensor or other type of exertion level sensor is automatically set during a parameter adjustment mode that utilizes an activity level measurement to determine when the patient is at a target activity level with which is associated an appropriate target pacing rate. In a preferred embodiment, the target activity level corresponds to casual walking (e.g., 2 mph at a 4% grade) with a target pacing rate selected as appropriate for that level of activity in the individual patient.

Abstract: The present invention relates to an apparatus and method for creating an printed circuit board including one or more waveguides having one or more reflective surfaces. Waveguides are embedded within a printed circuit board. A reflective surface is formed within the embedded waveguides by mechanically milling the printed circuit board. The reflective surfaces enable intra chip, chip-to-chip, or chip-to-component optical interconnections through the waveguides embedded within the printed circuit board.
