Abstract: A pair of electro-acoustic transducers, one functioning as a speaker and the other functioning as a microphone, are operatively coupled to a reference which in turn is in communication with a fluid. A regenerative frequency filtering loop is operatively coupled between the transducers and functions to apply amplified signal to the speaker and produce an acoustic signal which propagates through the medium. The acoustic signal is sensed by the microphone and coupled to the regenerative loop input. For certain frequencies, the spacing between the transducers together with the speed of propagation of sound through the fluid combine with the frequency filtering of the regenerative loop to cause the loop to regenerate at a frequency indicative of the relative speed between the reference and the fluid.
Abstract: A weighted vest includes a pair of mirror image front panels joined to a back panel to form a sleeveless weight supporting vest. A plurality of pliable easily conformed weight packets are secured within the vest interior by fabric attachment pads together with a combination of elastic bands and belts. The vest provides weight distribution particularly suited to activities of substantial acceleration such as sprint starting, American football or the like. A porous liner and mesh outer layer over certain areas of the vest allow heat to be vented from the vest interior. A pair of variable spring rate expansion joints are coupled between the front panels and the back panel passing over the shoulder, neck and collar bone region of the athlete's body to provide reduction of localized stress upon the athlete.
Abstract: A liquid applicator includes an elongated cylindrical body having an end cap within which a plunger is slidably moveable.

Abstract: An adjustable cable guide for archery bow provides a housing which supports a pair of rotatable pulleys upon which the cam cables of the bow are received. A slide mounting of each pulley supporting segment is adjustable by a threaded adjustment screw. The entire adjustable cable guide assembly is supportable upon the riser directly or may be supported upon the conventional cable guide bar which extends from the riser.
Abstract: A traffic signal device includes a plurality of illuminatable light assemblies such as red amber and green used to control traffic flow. A transparent element configured to fit upon the outer surface of the lens of a light assembly supports one or more opaque numerals corresponding to vehicle speed limits. The transparent member baring the speed limit numerals is placed upon the outer surface of the traffic signal lens to impose the speed limit numerals upon the light emitted by the light assembly when illuminated.
Abstract: A joint area formed by intersecting surfaces is provided with a caulk seal using a conventional caulking gun to apply an initial bead of silicone-based caulk to the joint. Thereafter, a spray of cleaning solvent is immediately applied to the caulk bead and the surrounding surfaces of the joint area to provide complete covering. Excess caulk is removed from the joint such as through finger wiping, to provide a smoothed caulk joint corner. A cloth fiber patch is soaked to saturation in cleaning solvent and is smoothly stroked across the smoothed joint surface to further finish the caulk material surface and to remove traces of excess caulk material from the adjoining or intersecting surfaces. In an exemplary embodiment, the cleaning solvent is used to caulk a tub and wall joint area of a typical bathroom facility and includes a formula of soft distilled water, glycol ether DPM, a surfactant and an antifoaming agent.
Abstract: A combination doll and toy puppy include interacting magnetic elements therein which mimic a face-licking action by the puppy. The doll includes a partially hollow head within which one or more magnets are movably supported behind the cheek portions of the doll's face. A battery-powered electric motor driven gear drive mechanism is operative within the doll's head to move the one or more magnets behind the doll's cheeks. The puppy includes a flexible extending tongue having a magnetic element supported in the end portion thereof. When the puppy is brought sufficiently close to the doll's face, the magnet in the puppy's tongue is attracted to the moving magnet within the doll's cheek area to mimic the face-licking action.
Abstract: A housing suitable for partial immersion in a pool or pond supports a plurality of electric lamps together with a plurality of fountain nozzles. The fountain nozzles are coupled to a nozzle flow distributor which is operative to direct water flow to one or more of the nozzles selectively. The directing of flow is accomplished by a motor-driven flow distributor operative under an electric module control. A plurality of electric lamps are supported within respective lamp assembly receptacles which in turn provide a flow of cooling water to maintain the lamp assemblies at a safe operating temperature.
Abstract: A generally cylindrical housing supports a pair of rotatable tubing wheels within the housing. Each rotatable tubing wheel supports a quantity of flexible tubing having one end extending outwardly through an aperture in the housing and the remaining end coupled to a rotatable coupler such that gas flow may be produced between the two outer ends of the two flexible tubings. Each rotatable wheel is operatively coupled to a spring-driven ratchet-controlled winding and rewinding mechanism. The rotatable coupler between the interior ends of the two flexible tubes allows for independent rotation of each tubing wheel with respect to the remaining tubing wheel.
Abstract: A cleaning device includes an outer container having an open upper edge and a closed bottom and side wall together with a nesting strainer shaped and sized to be received within the outer container. A plurality of apertures are formed in the lower portion of the side wall and bottom surface of the strainer to drain liquids therefrom. A lid shaped and configured to be received upon the upper edge of the container and strainer provides closure of the cleaning device. A pair of handles are independently secured to the strainer and outer container for convenient carrying.
Abstract: A plurality of color LEDs are commonly coupled to a source of operating supply. A plurality of switching transistors and current limiting resistors in series therewith are coupled to the color LEDs to control the current there through in response to switching transistor conduction. A microcontroller having an input signal and a plurality of outputs configured in response thereto is operatively coupled to the plurality of switching transistors to control the conduction and thereby illumination output of the color LEDs to achieve incremental color blending.
Abstract: A magnetic holder for cell phones includes a cup formed of a ferromagnetic material or the like within which a magnet is supported. The rear surface of the cup includes a double-sided adhesive pad to provide attachment of the cup to a vehicle dashboard surface or the like. The cup concentrates the force of the magnet along the frontal edges thereof. A friction ring encircles the frontal edges of the cup to provide enhanced retention of a cell phone secured to the cup by magnetic attraction between the internal magnet and the cell phone battery or other metallic portion thereof. Alternate embodiments are shown which provide different shapes of cup and magnet and which provide differing attachments such as suction cups or belt clips for retaining the magnetic holder. In a further alternate embodiment, the packaging provided for the cup holder is constructed to facilitate the multiple display of the a plurality of cup holders and packages in typical point of sale environment.
