Publication number: 20160194039Abstract: A link assembly for a track comprises a first side plate, and a second side plate coupled with the first side plate such that proximal surfaces of the first and second side plates are disposed in abutment with one another. The link assembly further includes a wear plate assembly that is coupled to a top face of the first side plate and a top face of the second side plate.

Publication number: 20140077843Abstract: The invention provides a digital modulator system for use in a fractional-N frequency synthesizer, said system comprising: a first pipelined modulator configured to receive a digital signal via a bus signal; a second pipelined modulator configured to receive a part of said digital signal; and said system is adapted to split the bus signal by passing least significant bits (LSBs) of said digital signal through the second modulator, combining the output of said second modulator with the most significant bits (MSBs) of said digital signal, and adapted to pass the combined signal through said first pipelined modulator. The combination of bus-splitting and pipelining in the modulator system is configured to provide an output signal to maximize the update rate of a multi-modulus divider of said fractional-N frequency synthesizer.Type: ApplicationFiled: May 31, 2013Publication date: March 20, 2014Inventors: Michael Peter Kennedy, Brian Patrick Fitzgibbon

Publication number: 20080077293Abstract: A method and system for extending the range of run-flat tires by providing ride height control. When the vehicle has a damaged tire or tires the ride height of an appropriate suspension system(s) is capable of being adjusted to achieve a level attitude for the vehicle thus preventing destructive loads from being placed on the damaged run-flat tire(s).Type: ApplicationFiled: September 5, 2007Publication date: March 27, 2008Applicant: LOCKHEED MARTIN CORPORATIONInventor: Patrick Fitzgibbons

Publication number: 20080001470Abstract: Disclosed is a redundant braking system for a vehicle. A controller may monitor a status of a hydraulic braking system, and during vehicle travel, automatically switch to a modulated electric braking system which is separate from the hydraulic braking system when the hydraulic braking system fails. The modulated electric braking system may utilize a brake acting on a drive shaft of the vehicle, and an operator-actuated switch may set a mode of the modulated electric braking system to a non-modulated parking brake mode.Type: ApplicationFiled: July 18, 2006Publication date: January 3, 2008Applicant: Lockheed Martin CorporationInventors: William Craig, Patrick Fitzgibbons

Publication number: 20070158400Abstract: A mail box configured to contain and reduce exposure to hazardous particulates, which includes a container having a deposit port at an upper end and a collection chamber at a lower end. There is at least one door at the upper end for mail to be placed into the deposit port. A normally open sealable bag is located in the collection chamber for receiving mail and for being sealed when the mail is to be removed from the container. There is a bag holder constructed and arranged to hold a bag in place and normally open so that in a first position, mail placed into the deposit port falls downwardly through the bag holder and into a bag in the collection chamber and which bag may be preliminarily sealed while in this position, and in a second position, the bag may be more securely sealed and removed from the bag holder.Type: ApplicationFiled: February 9, 2007Publication date: July 12, 2007Applicant: LOCKHEED MARTIN CORPORATIONInventors: Patrick Fitzgibbons, John Hoover, Glenn Kehley, John Swider, Mary Wilcoxen
