  • Patent number: 7642862
    Abstract: A digital phase locked loop includes a phase acquisition unit for producing a digital representation of the phase of a reference signal, a digital phase detector having a first input receiving a digital signal from, or derived from, the output of the phase acquisition unit, digital loop filter filtering the output of the digital phase detector, and a digital controlled oscillator generating an output signal under the control of the digital loop filter. A digital feedback loop provides a second input to the digital phase detector from the output of the digital controlled oscillator.

  • Patent number: 7621484
    Abstract: A rotor kite is characterized by a stabilizer bar connected between the wing and stabilizer ring components of the kite to maintain the wing and the stabilizer ring in a perpendicular orientation with respect to each other during flight. The stabilizer bar is connected at its ends with the inner edge of the annular stabilizer ring so that the bar extends across the inner diameter of the ring. The wing is connected with the bar at multiple locations within the stabilizer ring, with the bar extending normal to the longitudinal axis of the wing. When the kite is released, the wind rotates the wing which in turn lifts the kite into the air. The stabilizer acts as a rudder to maintain the wing perpendicular to the wind direction.

  • Patent number: 7610696
    Abstract: An adjustable fit insole system for shoes includes an insole member formed of flexible, resilient cushioning material that is removably inserted within the foot-receiving chamber of the shoe, the insole member and the shoe having corresponding heel, arch, ball and toe portions. In order to vary the internal width and girth dimensions of the ball portion of the chamber, a width adjustment pad of a desired thickness and/or hardness is removably connected with the bottom surface of the ball portion of the insole member, thereby to permit the user to customize the fit of the shoe. The top surface of the insole member is contoured to position the foot relative to the insole, and the bottom surface of the heel portion of the insole member is provided with an anti-slip stabilizing arrangement, thereby to prevent sliding movement of the insole member relative to the shoe.

  • Patent number: 7597160
    Abstract: A four wheel drive system for bilaterally symmetric vehicles is characterized by separate drive systems for the front and rear wheels. Each drive system is operable to independently drive each wheel. The rear wheels of the vehicle are steering wheels which are connected with the vehicle frame for independent rotation about a vertical axis. Steering and driving of the wheels is controlled by a controller. The combination of independent steering for the rear wheels and independent powering of all four wheels provides the vehicle with a zero turning radius for improved mobility as well as improved traction on unstable surfaces.

  • Patent number: 7575459
    Abstract: A plug and socket connector arrangement for electrical or fiber optic cables includes a pair of tubular locking sleeves mounted for axial and rotational displacement on the plug and connector bodies, which locking sleeves have adjacent ends provided with internal and external screw threads, respectively. The adjacent sleeve ends each contain a plurality of circumferentially spaced longitudinal slits that define a plurality of resilient threaded sectors. After the plug and socket connectors are brought into connected engagement, the locking sleeves are successively displaced from retracted separated positions axially together toward an adjacent locked position, whereby the resilient inner sleeve sectors are initially radially expanded, and the resilient outer sleeve sectors are subsequently radially contracted. The inner and outer screw threads are thus brought into threaded engagement, whereupon the locking sleeves are slightly relatively rotated to lock the sleeves together.

  • Patent number: 7568939
    Abstract: A plug-in connector arrangement includes a terminal block containing a chamber in which are mounted a horizontal bus bar having a transverse wall, and a resilient contact having a fixed horizontal leg portion, an intermediate portion bent upwardly from the first leg portion, and an outwardly biased second leg portion reversely bent back above the first leg portion. The second leg portion contains a clamping end portion that extends through a conductor opening contained in the first leg portion. The clamping portion includes at least two discrete clamping surfaces so arranged that when a bare conductor is inserted into the conductor opening, the conductor circumferential surface is selectively engaged by one or more of the clamping surfaces in accordance with the diametrical size of the conductor. The conductor is biased by the clamping portion toward electrical engagement with the bus bar transverse wall.

  • Patent number: 7566234
    Abstract: A connector block arrangement includes a first connector block housing having a row of first contacts, a second connector block housing having a row of second contacts in engagement with the first contacts when the connector block housings are in a connected condition, a conductive jumper device having a base portion and a plurality of resilient fingers normally connecting together a group of the second contacts, and an electrically-insulated code device carried by one of the housings for selectively disengaging from the jumper device at least one of the contacts of the second contact group. The code device has a planar generally comb-like configuration including a base portion arranged in an opening contained in either one of the connector block housings, and at least one code bar portion operable to separate a resilient finger of the jumper device from the corresponding contact to be disengaged.

  • Patent number: 7563122
    Abstract: An electrical connector assembly includes a quick-fastening locking arrangement for locking together a plug member and a socket member, including a locking peg connected with one of the plug and socket members, and a cylindrical locking cam connected with the other member, which locking cam is pivotable through a relatively small angle between locked and unlocked positions relative to the locking peg. The cylindrical locking cam is mounted at one end of the plug member adjacent the socket member for rotation about a transverse axis relative to the collinear axis of the plug and socket members. In one embodiment, the socket member is mounted in an opening contained in a mounting wall to which the locking peg is fastened. In a second embodiment, the locking peg is fastened directly to the socket member.

  • Patent number: 7540109
    Abstract: An humane trap for small animals, such as cats, includes a housing having rigid bottom, top, side, front and rear end walls which cooperate to define an animal-receiving chamber, the front end wall being guided for vertical movement between opened and closed positions relative to the other housing walls. A retaining rod is axially displaceable within the chamber between a retaining position in which an end portion of the rod extends through a retaining opening contained in the second wall to maintain the same in the open position, and a released position removed from the retaining opening, whereby the second wall is displaced by gravity downwardly toward the closed position. The retaining rod is released either by a food retention plate that is engaged by the animal in the trap, or by a remotely controlled solenoid arrangement.
