Abstract: The training device assuring a proper grip utilizes a thin sheet wrap sized to wrap around an outside grip surface of a racket handle. A non-domed membrane switch is retained by the thin sheet wrap. A releasable element is utilized to secure the wrap on the racket handle. This releasable element can be a releasable adherent. A portable power source is electrically coupled to an audible alarm, both of which are in turn electrically connected to the switch. When the switch closes, the alarm sounds. Other than a switch, piezoelectric pressure sensors can be utilized. The method includes removably mounting at least one membrane switch with a wrap about a racket handle, mounting a portable power supply in an audible alarm on the racket, electrically connecting together the power supply, alarm and switch, compressibly closing the switch with a proper hand grip over a distance which does not exceed the thickness of the wrap, and audibly announcing the closure of the switch by activation of the alarm.

Abstract: The training device, to assure a proper grip, utilizes a thin sheet wrap sized to wrap around an outside grip surface of a racket handle, or a golf club handle or a hand grip surface. A non-domed membrane switch, is retained by the thin sheet wrap. A releasable element, such as a glue, strap or attachment mechanism, is utilized to secure the wrap on the handle. A portable power source is electrically coupled to an audible alarm, both of which are in turn electrically connected to the switch. When the switch closes, the alarm sounds. Piezoelectric pressure sensors can also be utilized.

Abstract: The present invention relates to an improved intravascular catheter. One improvement relates to the catheter body wherein the body is made of an inner tube of high temperature thermoplastic having a low coefficient of friction (for example fluorinated polymer). The extruded inner tube carries on its periphery a plurality of gear bodies. Each gear body further includes opposing elongated tangentially extending gear teeth spaced above the periphery of the tube. Wires are wound about the tube and over the gear teeth. An overcoat of low temperature thermoplastic covers the entire catheter and is interstitially disposed beneath the tangential teeth and the gear supported portions of the wire.The overcoat of low temperature thermoplastic over the high temperature fluorinated polymer produces an interlocking gear thereby enhancing the lamination of both low and high temperature polymers. This coupled gear design makes possible a mechanical anchoring to fluorinated polymers such as TEFLON.RTM.

Abstract: The tripod stand is used to elevate the bottom of a can. Three legs protrude outward from a support platform intersection. The intersection is located below the can bottom. The legs in the intersection establish and lie within a singular support plane beneath the can. Each leg has a foot formed at its remote end. The foot is a compact structure having a lower body protruding below the support plane and having a raised lip protruding above the support plane. The raised lip has a substantially vertical face with an inwardly directed tab near its uppermost periphery. Upon placement of the can bottom on the support plane, the tab locks over the edge of the can bottom. In one embodiment, each foot is generally spherically shaped and the lip is formed as a cut-out from the sphere. In another embodiment, each foot forms a tiered structure defining multiple levels of support surfaces for predetermined can bottom diameters.

Abstract: The anchoring system includes a generally cylindrical anchor having first and second longitudinal portions. The first longitudinal portion includes a female threaded interior cylindrical chamber. The second longitudinal portion includes a lower chamber having a bore smaller than the threaded chamber. A pair of radial slots extends longitudinally through the second portion of the anchor. An elongated pin, having a length which does not exceed the second longitudinal portion of the anchor,is driven into the lower cylindrical chamber of the anchor. The pin expands the outer cross sectional dimension of the lower portion of the anchor. A male threaded screw completes the anchoring system. The threaded surface of the screw is complementary to the female threaded interior chamber.

Abstract: The accessory carrier is mountable on a window visor of an automobile. The visor has a predetermined thickness and the accessory carrier is a three layer, generally planar, composite carrier having a thickness substantially the same as the visor thickness. One outer layer of the carrier has a longitudinal slot therein through which a tinted, planar viewing screen is laterally extendable. The viewing screen has opposing sawteeth laterally extending from opposing sides thereof such that the sawteeth interact and coact with the terminal ends of the longitudinal slot of the outer layer of the carrier. The sawteeth provide digital or precise positioning of the viewing screen with respect to the accessory as well as the window visor since the carrier is mounted on the visor itself. The accessory carrier also includes a closable, longitudinal slot in the opposite outer layer. This layer is normally exposed to the occupant of the automobile.

Abstract: The reversible triangular box is a generally rectangular sheet divided into three rectangular sections, each containing a front and back face, by two major folds. Safety sign indicia is printed on one face while advertising indicia is printed on the other face. The minimal construction of the reversible triangular box includes two triangular side sections extending from the intermediate second section. Advertising indicia is printed on one face of each triangular side section and safety sign indicia is printed on the other face. A pair of complementary side locking tab and side locking slot combinations are utilized to removably couple or link a respective triangular side section to a first main box section. A minimal construction box has a first and a second handle portion, one of which extends from a top edge region of the first section and the other one extends from the top edge region of the third section. A retaining device holds the first and second handle panels together when they are juxtaposed.

Abstract: One endoscopic surgical tool is used in conjunction with a laser that is powered through a small diameter laser power tube. The tool includes a bendable, rigid tube having a lumen sufficiently larger than the laser power tube such that upon application of an axial, inboard directed force, the laser power tube is axially compressed within the lumen of the bendable tube. The tool further includes a coupling tube which provides suction through the lumen of the bendable, rigid tube. Further enhancements of this tool include an axial movable, soft touch casing surrounding the tube. The tool may include a handle at the proximal end of the tube and a branch coupler and second bendable, rigid tube with suction control valves for the primary bendable tube and the branch bendable tube.

Abstract: The temperature compensated air/fuel ratio controller is used in conjunction with an internal combustion engine. The method includes electronically sensing the oxygen content and the temperature of the exhaust gas generated by the engine. It was discovered that the oxygen content signal varies in a curvilinear manner with respect to the temperature. The oxygen content signal is therefore compensated in both the linear and non-linear signal regions. The compensated oxygen content signal is then used to control the air/fuel ratio of the engine. In a working embodiment, the temperature compensated air/fuel ratio controller utilizes a zirconium oxide oxygen sensor. One type of circuitry designed to compensate the oxygen content signal in both the linear and non-linear signal regions includes, in one embodiment, electronic circuitry that segments the curvilinear function into linear segments and generates a plurality of linear compensatory signals which are added to the oxygen content signal.

Abstract: The device tests the pressure and the positioning of a player's hand on the grip of sports equipment. The device generates an audible signal of confirmation when a lower threshold of pressure at predetermined locations on the grip are achieved. In many sports a major hindrances to a player in perfecting his or her same is the lack of maintaining a proper grip on the sports equipment. An important aspect of many sports including tennis, racquetball, golf, baseball and hockey is to maintain proper hand position and a firm grip on the sports equipment used. This sports equipment includes, amongst others, the tennis racket in tennis, the racket in racquetball, the golf club in golf, the bat in baseball and the stick in hockey. Proper grip and the ability to properly maintain the correct grip on the equipment is of paramount importance to consistent play.
