Patent number: 7377445Abstract: The circuitry introduced in this invention selectively slows down the functioning of an electronic circuit by maintaining a particular state for a prolonged period of time. This circuitry is used not only to achieve the desired effect in maintaining security from electronic thieves trying to circumvent codes but also in other applications such as enabling a circuit to continue to function in the event of a brief loss of power. For example, in an RFID system, if a reader is frequency hopping, a tag loses power for as long as about 400 milliseconds when the reader changes to other frequencies. In a preferred embodiment, the disclosed circuitry is used in conjunction with a destruct sequence.Type: GrantFiled: October 31, 2005Date of Patent: May 27, 2008Assignee: Alien Technology CorporationInventors: Roger G.

Patent number: 7377480Abstract: A servomechanism includes a controller which dynamically estimates the resistance of the solenoid coil in an electrohydraulic valve as part of determining a level of electric voltage to apply to open the valve. The servomechanism receives a current setpoint designating a desired electric current level and senses the actual level of current flowing through the coil. A proportional term is derived from the current setpoint and the actual level of current. Creation of a derivative term is based on the difference between the current setpoint and the actual level of current. A feedforward term is produced by estimating the resistance of the electrohydraulic valve and limiting the feedforward term to a predefined range of acceptable values. The proportional term, derivative term, and the feedforward term are summed to define a desired voltage level, and a PWM signal for driving the electrohydraulic valve is generated based on the desired voltage level.Type: GrantFiled: March 18, 2005Date of Patent: May 27, 2008Assignee: HUSCO International, Inc.Inventors: Keith A.

Patent number: 7377484Abstract: A multi-functional ratchet includes first and second bars with left and right axially opposed ends respectively. Each bar is provided with a channel formed therein with a longitudinal length that is less than the longitudinal length of the bar. The apparatus further includes first and second beams with axially opposed proximal and distal ends. The beams are pivotally attached to the bars. Each beam is provided with a channel formed therein with a longitudinal length that is less than a longitudinal length of the beam. A mechanism winds a strap about a central portion of the ratchet when the first and second beams are laterally displaced away from equilibrium. The winding mechanism is connected to the bars and the beams respectively. The strap is freely rotated about the central portion while the first and second beams are maintained at a static position.Type: GrantFiled: June 2, 2007Date of Patent: May 27, 2008Inventor: Marcus Williams

Patent number: 7377485Abstract: A three-phase drive motor is utilized to operate a boat lift. In one example, a drive motor arrangement for replacing manual drives on an existing boat lift winch shaft comprises a worm gear box with a worm driven by an integrally mounted motor on the worm gear box. A worm gear is mounted on a tubular cross shaft extending outwardly on opposite ends of the gear box. The bore of the cross shaft is of size to slide over an existing winch drive shaft. The tubular shaft has a drive connection that mates with the existing drive connection on the winch box shaft. As shown a disc that effects drives to a mating disc on the winch box shaft. After removing the manual ratchet and wheel on an existing winch shaft, the tubular shaft of the worm gear box can be put into place and a suitable fastener is used to hold the drive connection on the tubular shaft in engagement with the drive member on the winch shaft.Type: GrantFiled: February 28, 2007Date of Patent: May 27, 2008Assignee: Commander Products LLCInventor: Ellis W.

Patent number: 7377488Abstract: A landing gear assembly comprises a first leg member adapted to couple to a vehicle frame member, and a second member operably coupled to the first leg member and moveable between a raised storage position and a lowered in-use position. The landing gear assembly further comprises a flexible member operably coupled with the drive mechanism and the second leg, such that the drive mechanism extends the flexible member and moves the second leg from the storage position to the in-use position, and wherein the flexible member is adapted to support a weight exerted on the first and second legs. In certain embodiments disclosed herein, the flexible member comprises a ribbon constructed of natural fibers. Other embodiments comprise additional pulleys and flexible members adapted to raise the second leg member from the in-use position to the raised storage position.Type: GrantFiled: June 6, 2006Date of Patent: May 27, 2008Assignee: SAF-Holland, Inc.Inventor: Randy L. Schutt

Patent number: 7377490Abstract: A fence assembly includes anchor brackets mountable to a first support wall. An anchor post is conjoined to the anchor brackets, has opposed top and bottom ends and is formed from rigid and non-corrosive material. Couplings are conjoined to the anchor post, are detachable therefrom and positional along a length thereof. A cylindrical housing defines a cavity therein, is provided with a slot and is formed from rigid and non-corrosive material. A screen passes through the slot, is formed from transparent material and can be adapted along at least a 180 degree arcuate path when extended. A rectilinear auxiliary post is permanently attached to a distal screen end, travels along an entire length thereof and is situated to an exterior of the housing. Latching brackets are connected to the auxiliary post and are engageable to a second support wall.Type: GrantFiled: July 25, 2005Date of Patent: May 27, 2008Inventor: Bahman Khosravian
