摘要:
A muscle growth regulating factor includes polynucleotide and polypeptide sequences, promoter sequences, constructs comprising the sequences, and compositions for regulating muscle growth and treating diseases associated with muscle growth. The present sequences can be used in identifying animals with altered muscle mass, and for selective breeding programs to produce animals with altered muscle mass.

A harness for an upper extremity below-elbow prosthesis. The harness includes a humeral cuff having medial and lateral pivot arms configured to removably attach to the socket of a below-elbow prosthesis. The humeral cuff enables a user to suspend the prosthesis without the need of a shoulder strap/harness or body harness. A cable system is affixed to the pivot arms and includes a wheel coupling the pivot arms to the control arm of a hook of the below-elbow prosthesis, thereby enabling users to operate the hook by simple flexion and extension of their arm.
摘要:
A positive lock mechanism having a compression spring rod with a housing, a rod member having an inner end in said housing and an outer end axially outwardly of a housing end. One or more compression springs extend between a guide member and an end of the housing. A positive locking mechanism is provided to prevent movement of the rod member in a longitudinal direction. The lock mechanism is controlled by a wire and cable assembly operated by a lever.

Modular convertible furniture systems include a pair of similar open-ended box frame assemblies which are nestable one within the other. A pair of slotted support rails are attached pivotally at respective opposing corners of one of the box frame assemblies so as to be movable between raised and lowered positions. When in a raised position, the rails provide a support for a solid board plank thereby becoming a seat back (e.g., for a chair, love seat, or sofa-type arrangement). When the rails are in a lowered position substantially parallel to the ground, the two box frame assemblies may be oriented back-to-back so as to provide a support for a mattress thereby converting the structure into a bed arrangement, for example. The box frame assemblies can be positioned on different sides and ends thereby allowing formation of tables and/or shelving as may be desired.

A scope for a firearm can be used for a gun sight. The scope comprises a main tube that contains imaging optics therein. In certain embodiments, the main tube comprises a single continuous tubular body extending uninterrupted from a widened proximal end portion through a narrow medial portion to a widened distal end portion. An objective is disposed in the widened distal end portion of the tubular body and an ocular is disposed in the widened proximal end portion of the continuous tubular body. A zoom selector ring is located about a circumference of the narrow medial portion of the continuous tubular body. The zoom selector ring can be used to provide optical zoom. In one arrangement, the zoom selector ring includes a plurality of segments arranged circumferentially about the circumference of the narrow medial portion. A flexible erector assembly that includes erector optics may be included in the main tube. This flexible erector assembly may flex to adjust windage and elevation.

A compact, light-weight binocular includes motorized optical adjust. The binocular includes a pair of telescopic sections connected to a bridge section positioned between them. Each telescopic section includes an eyepiece lens group, a prism element, an intermediate focus lens element, and a fixed objective lens. A high-speed focus motor and a speed-reduction gear assembly are positioned on the bridge section and operably coupled to the intermediate focus lens elements. A user-operated focus control is selectively operated by a user to activate the focus motor and adjust focus of the binocular.
摘要:
A stationary rowing machine or rowing simulator, were the cockpit components of an elite rowing shell are used where practical. The motion of the rower as occurs on the water is then transferred by a ¼ size pulley that is located roughly 18′ outboard of the oarlock . The pulley is connected to a cable transferring the rowing motion to bicycle wheels, at stern and bow ends, that sit on rollers with grooves that detain the tires. The rowing machine frame and roller frame are coupled together in a way that causes them both to swivel on a radius at the proximity of that occurring in an elite rowing single. The spinning motion of the wheels offers counter-balance allowing the rower to achieve balance. The rowers weight rests on the wheels replicating the weight of the rower as it would rest on the hull of the boat running on the water.
