Abstract: A golf swing training device that fits on the inner down swing arm and optionally it has a thumb restraint extension. The device comprises a shell contoured to fit the inner arm from the wrist to the lower portion of the upper arm which is strapped to the arm. The device cocks the arm slightly but fully extends the arm for the back swing and down swing and aids the golfer in forming the right habit by muscle memory to extend the arm during the golf swing. The device is flexible laterally so that a snug fit between the device and the arm can be obtained. The device can twist to accommodate the twisting of the arm during the golf swing. The device resists bending of the forearm about the elbow to keep the forearm extended. The thumb extension inhibits flexure and side to side movement of the thumb during the golf swing. The thumb extension can be detachably attached to the shell.

Abstract: An improved padlock having a shackle retainer assembly that can be removed without removal of the padlock key locking assembly and/or convertible from a key retaining to a key nonretaining lock, or vice versa, by removal or insertion of a pin on the driver end of the key cylinder assembly.

Abstract: This invention relates to the zonal transmission of data by the modulation of the light output of arc lamps or discharge lamps; including the visible or invisible light output of fluorescent lamps, mercury vapor lamps, high or low-pressure sodium lamps, metal-halide based lamps, or other arc or discharge lamps. The method results in an easily installed, easily maintained, and economical to purchase, optical-wave communications system which exploits the existing infrastructure of a building or facility to facilitate the transmission of data in individual zones; thereby facilitating the transmission of wide-area as well as zonal-specific data to compatible receivers, and further facilitating the determination of location of remote devices or users, and the delivery or exchange of information or data, utilizing limited range transmission techniques.

Abstract: The present invention is a bifurcated modular graft for repairing body lumens. In one embodiment, the graft includes two elements, each element being fabricated from material which is flexible. The first element embodies a tubular docking section which bifurcates into left and right tubular limbs. The first element is adapted to be inserted into vasculature of a patient so that the device spans and is supported by a point of bifurcation. The second element is made from a single tubular segment and is adapted to engage the docking section of the first element. The first and second elements are sealed to each other and within the vasculature by expanding support structures.

Abstract: A biological stent-graft and a method of making the same wherein a stent is surgically implanted in the lumen of an artery of a mammal, harvesting the stent-graft precursor after the stent has been incorporated into artery wall, fixing the harvested stent-graft precursor, and washing the same to yield a biological stent-graft.

Abstract: A graft for repairing defects in arteries is formed from a flexible graft and at least one attachment system. A device and method is disclosed for implanting a graft within the vasculature of a patient, in which the graft is inserted into the patient at a different stage than the attachment systems, and which allows for direct percutaneous insertion of the graft and attachment systems. The method permits control over the position of the graft in the vasculature during the course of deployment of the graft and attachment systems by providing for traction forces to be applied to opposing ends of the graft.

Abstract: An improved padlock having a shackle retainer assembly that can be removed without removal of the padlock key locking assembly and/or convertible from a key retaining to a key nonretaining lock, or vice versa, by removal or insertion of a pin on the driver end of the key cylinder assembly.

Abstract: A surveillance system is provided including a platform having a plurality and variety of cameras or sensors mounted thereto, and a base enclosure adapted to accommodate a power supply, a variety of electronics and other equipment for controlling and providing power to the surveillance equipment. The base is constructed to be tamper resistant and immovable by manual means. A substantially hollow support pole includes a lower portion detachably mounted to the base, and an upper portion mounted to the platform. Wires and cables for connecting the surveillance equipment with the electronics and power supply are run through the support pole. Power to the system may be supplied through existing power sources, for example a 120V power source. A current breaker secured in an environmentally protected housing on the exterior of the surveillance system connected to the power supply and the electronics and surveillance equipment.
