  • Patent number: 6930594
    Abstract: An electronically-active vehicle gear-shift knob (10) consisting of a hand-grasping section (12), an electronics enclosure (44) that is attached to an upper edge (14) of the hand-grasping section (12), and an electronics control circuit (90) consisting of a transmitting circuit (92) and a remotely located receiving circuit (94). The enclosure (44) includes a set of four pushbutton switches (92E) that are connected to the transmitting circuit (92). The closure of any one of the pushbutton switches (92E) allows the transmitting circuit (92) to produce an RF output signal (19) that is radiated via an antenna (92H) to the receiving circuit (94). The receiving circuit (94) subsequently processes the RF output signal (19) and produces an output control signal (29) that energizes an LED light corresponding to the specific pushbutton switch (92E)that has been closed.

  • Patent number: 6929268
    Abstract: A flight case (24) for shipping and supporting an audio mixing console (26), having a main platform frame (28) that includes a pair of collapsible legs (30) each with reversible swivel casters (36) and a plurality of upright sockets having gas springs (48). When the flight case (24) is positioned on its side for transportation the casters (36) face outward; when positioned horizontally the casters (36) are rotated downward for resting on a hard surface. A sub frame (50) is located inside the frame (28) and is configured to receive the audio mixing console (26). A removable top (54), with side casters (56) and locking mechanisms (58) is placed over the frame (50). When the locking mechanisms are rotated, the frame (50) and the top (54) are elevated by the gas springs (48), permitting the top (54) to be removed leaving the frame (50) for supporting the audio mixing console (26) exposed ready for use. The frame (50) is then pulled outward forming a shelf creating room for a sound engineers legs.

  • Patent number: 6866001
    Abstract: A fold-away transport platform that is attached to a stern portion of a boat and that is used for carrying sizeable items. The platform (24) consists of a pair of side supports (28), each having a first end and a second end. A plurality of cross members (38) are disposed between the side supports which form the platform, that when extended, is cantilevered outward away from the stern of the boat. Pivoting hinge brackets (42) are attached onto the side support first end and the boat stern inside a transom (26b). At least two diagonal braces (52) are removably fastened to the boat on a lower end and to a cross member such that the braces (52) may be detached and the platform pivoted into the boat for transportation and storage. A second embodiment attaches the platform to the boat stern rail instead of the inner surface of the transom.

  • Patent number: 6857582
    Abstract: A vehicle windshield spraying and lighting assembly (10) that includes a nozzle and light housing (12) that is designed to be attached to a vehicle's (80) hood cowling or hood (82). The housing (12) houses a rear facing adjustable spray nozzle (24) and a forward facing LED (30) and strobe light (34). The LED and strobe light are operated by an electronic control circuit (50) that is enclosed within an electronic enclosure (52) designed to be attached to an accessible structure on the vehicle (80). The circuit (50) includes a single-pole, five-position switch (51) that allows the LED (30) and strobe light (34) to be operated as follows: first position: LED and strobe light off, second position: LED on, strobe light off, third position: LED on, strobe light flashing, fourth position: LED off, strobe light flashing, fifth position: LED off, strobe light on.

  • Patent number: 6827479
    Abstract: A uniform small particle homogenizer for liquid product comprising a pair of intensifier cylinder pumps (20) driven by a hydraulic system (22). The pumps have a power stroke side and a suction stroke side, and a pair of proximity sensors (24) that interface with each pump to detect forward and rearward movement. A microprocessor (26) with timing capabilities controls the sequential operation of each pump with the power stroke of each pump timed to alternately produce a flow of the liquid product with a precisely timed flow overlap period from the alternating pumps. Since the power stroke takes a longer time than the suction stroke, the instant each power stroke is started the opposite pump is timed to hesitate and slightly overlap until a constant product flow-rate is produced from the alternating pumps, which eliminates large variances in pressure and therefore achieves uniformity in product particle size.

  • Patent number: 6819769
    Abstract: A compilation of improvements and modifications to U.S. Pat. No. 5,392,358 which discloses an electrolytic loudspeaker assembly (10) which reproduces a broad band of audio signals. The assembly (10) is comprised of a thin, non-magnetic capacitive transducer (12) which consists of compound diaphragm (14) that is further comprised of a center section (16), a front section (20) and a rear sect compound diaphragm (14) is enclosed by a frame assembly (32). The improvements and modifications to the assembly designs for a center section (16A, 18A); three designs each for a front section (20A, 24A, 28A) and a rear section (22A, 26A, 30A); three designs for a frame assembly (32A, 34A, 36A) and two designs for a transducer driver unit (46, 48). The basic design of the assembly (10) is also augmented by the addition of an acoustic wave diffuser, reflector, and absorbing assembly (40) and an acoustic baffle structure (44).

  • Patent number: 6804362
    Abstract: An advanced design for an electrostatic and an electrolytic loudspeaker assembly (10) that comprises a compound diaphragm (12) sandwiched between a first metal stator (40) and a second metal stator (60), wherein each stator includes a multiplicity of perforations (41,61). All the sides of the stators (40,60) as well as the inside surface of the perforations (41,61) are coated with an insulating material (90) also known as ACOUSTAGUARD™ (90) which includes a base coat (92) and a sealing and pigmentation coat (94). The coats (92) and (94) are applied by a unique process that allows ACOUSTAGUARD™ to be applied at room temperature by preferably a spraying technique. The application of ACOUSTAGUARD™ avoids any arcing or corona discharge between the two stators (40,60) which can distort the audio output and damage the loudspeaker assembly (10).

  • Patent number: 6793076
    Abstract: A glass bottle protective enclosure (10) designed to protect a glass bottle (100) in the event the bottle is subjected to an impact shock. The enclosure is provided with a leak-proof seal and is particularly adapted for protecting glass bottles (100) containing toxic injectable medication. The enclosure (10), which is preferably made from a transparent plastic, consists of a lower bottle container (12) which includes a base (14) and a plurality of shock absorbing protrusions (30), which are located to allow a bottle label to be clearly visible, on the base (14) is located at least one sensor cavity (120) into which is inserted an enclosure leakage sensor (122) consisting of either a water soluble sensor (124) or an electronic sensor (126). Both of which provide an indication if a bottle leakage occurs. To complete the enclosure (10) the container (12) includes a threaded bottle container cap (36) which includes a plurality of cap shock absorbing protrusions (52).
