Publication number: 20220266737Abstract: A sliding mattress accessory is used with an existing mattress support system coupled to an RV slide-out. The accessory includes a secondary with a fixed head section and a long deck section coupled with a hinge. The system also includes two long sliding rails longitudinally aligned and mounted to the bottom surface of the secondary deck and the top surface of the primary deck used with the existing mattress support system. The system also includes at least one support mounted on the top surface of the primary deck that supports the fixed head section. The two sliding rails and the fixed support are the same height so that the entire secondary deck is elevated approximately 3 inches above the primary deck. A lock mechanism is provided to prevent the secondary deck from moving longitudinally over the primary deck. When assembled, the secondary platform is aligned and registered over the primary deck, and a mattress is placed over the secondary deck.Type: ApplicationFiled: February 24, 2022Publication date: August 25, 2022Inventor: Thomas Lancaster

Patent number: 10305577Abstract: A high-linearity linearizer system includes a multi-stage linearizer circuit formed by cascading multiple linearizer circuits. The multi-stage linearizer circuit is configured to pre-distort an input signal to generate a pre-distorted signal. A non-linear high-power amplifier (HPA) having non-linear characteristics is coupled to the multi-stage linearizer circuit and is configured to amplify the pre-distorted signal. Pre-distortion characteristics of the multi-stage linearizer circuit are configured to counter the non-linear characteristics of the non-linear HPA and to compensate a non-linearity of the non-linear HPA to achieve a desired level of linearity.Type: GrantFiled: August 21, 2015Date of Patent: May 28, 2019Assignee: Lockheed Martin CorporationInventors: Marc Ronald Bjorkman, Kim Thomas Lancaster, Douglas V. McKinnon, Novellone Rozario, Jason Michael Teixeira

Patent number: 10075310Abstract: An adaptive linearizer system includes an adaptive linearizer circuit that is configured to pre-distort an input signal based on one or more control signals to generate a pre-distorted signal, and a non-linear high-power amplifier (HPA) having non-linear characteristics that is coupled to the adaptive linearizer circuit. The nonlinear HPA amplifies the pre-distorted signal. The pre-distortion characteristics of the adaptive linearizer circuit provide for countering the non-linear characteristics of the non-linear HPA and compensating a non-linearity of the non-linear HPA.Type: GrantFiled: August 26, 2015Date of Patent: September 11, 2018Assignee: LOCKHEED MARTIN CORPORATIONInventors: Marc Ronald Bjorkman, Novellone Rozario, Jason Michael Teixeira, Douglas V.

Publication number: 20070110811Abstract: Methods for reducing the T-cell mitogenicity of lectin compositions are provided. In one aspect this is achieved by chemically modifying mitogenic lectin compositions under optimized conditions. Additionally or alternatively, the reduction in T-cell mitogenicity is achieved by removing unmodified subunits chemically modified mixtures. Modified lectin compositions with reduced T-cell mitogenicity are also provided as are uses of the inventive compositions.Type: ApplicationFiled: October 19, 2006Publication date: May 17, 2007Inventors: Thomas Lancaster, Wenyi Cai, Ryan Faucette, Matthew Pecukonis, Todd Zion

Publication number: 20070101649Abstract: The invention relates to a security barrier apparatus. Some embodiments of the present invention may be used in conjunction with a previously existing security gate or perimeter and other embodiments may be used as stand-alone security barrier gate systems. The various embodiments of the security barrier apparatus comprise a passive security gate apparatus that is capable of withstanding the force of an object, such as a vehicle, of up to 1.1×106 ft-lb/s wherein the driver of the object is attempting to gain entrance through the security gate apparatus.Type: ApplicationFiled: January 27, 2006Publication date: May 10, 2007Inventors: Joe Anderson, Victor Kaminsky, Thomas Lancaster, Douglas Hornstra, Michael Light, James Powers, Richard Schenk

Publication number: 20070099820Abstract: A conjugate that includes a drug covalently linked to a polymer. Upon administration, the conjugate is digested by an enzyme that is present at the site of administration thereby releasing a therapeutic agent. The conjugate may demonstrate substantially the same pharmacokinetic and pharmacodynamic behavior as the drug itself. A material for controllably releasing a conjugate in response to the local concentration of a molecular indicator. The material includes a plurality of conjugates and a plurality of multivalent cross-linking agents. The polymers of the conjugates include an analog of the indicator within their covalent structure. The multivalent cross-linking agents include cross-link receptors that interact with the indicator analog and thereby cross-link the conjugates.Type: ApplicationFiled: October 19, 2006Publication date: May 3, 2007Inventors: Thomas Lancaster, Matthew Nalewanski, Todd Zion

Publication number: 20050214539Abstract: Methods for making porous articles are described, along with articles and structures which can be made by these methods. The methods typically involve polymerization of a carbon-containing precursor in the presence of an amphiphilic molecular structure, followed by carbonization to make a final product. Articles of the invention are generally porous, carbon-containing, and can have one or any number of features including crystallinity, electrical conductivity, and porosity of a specific and advantageous nature.Type: ApplicationFiled: April 13, 2004Publication date: September 29, 2005Applicant: Massachusetts Institute of TechnologyInventors: Jackie Ying, Javier Garcia-Martinez, Thomas Lancaster
