Patent number: 8728602Abstract: Adhesive systems may be fabricated to include first and second solid adhesion structures. The first adhesion structure may require an applied normal preload force to achieve adhesion to a surface. The second solid adhesion structure may be separate from but joined to the first adhesion structure such that both adhesion structures are jointly adherable to the surface upon application of the normal preload force.Type: GrantFiled: April 28, 2008Date of Patent: May 20, 2014Assignee: The Charles Stark Draper Laboratory, Inc.Inventors: David J. Carter, Jonathan Bernstein, Peter Kerrebrock, Arnis Mangolds

Patent number: 7137465Abstract: A crawler device for traversing in a confined environment, searching victims or inspecting defections, comprises an elongated flexible drive shaft extending along a central axis between a proximal end and a distal end, a motor operatively connected to the drive shaft for turning the drive shaft, and a plurality of segments disposed over the drive shaft. Any two adjacent segments are joined by an articulate joint. Each segment has a wheel assembly including drive wheels. At least two segments further include a gear assembly operatively connecting the wheel assembly to the drive shaft. Turning the drive shaft provides distributed traction force to the drive wheels of the at least two segments, and thereby drives the crawler device.Type: GrantFiled: October 2, 2003Date of Patent: November 21, 2006Assignee: The Charles Stark Draper Laboratory, Inc.Inventors: Peter A. Kerrebrock, Jamie M. Anderson, William W. McFarland, Jr., Thomas G. Ogrodnik

Patent number: 6502657Abstract: The transformable vehicle comprises a central chassis assembly having first and second distal ends with an axis passing therebetween, a first wheel assembly mounted to the first distal end, and a second wheel assembly mounted to second distal end. A multifunction transformable vehicle comprising at least two configurational states: a stowed state and a transformed state. In the stowed state, the transformable vehicle comprises a compact structure suitable for storage, transport or deployment. During transition from the stowed state to the transformed state, the first and second wheel assemblies move longitudinally outward along the axis to reveal the central chassis assembly.Type: GrantFiled: March 14, 2001Date of Patent: January 7, 2003Assignee: The Charles Stark Draper Laboratory, Inc.Inventors: Peter A. Kerrebrock, Robert Larsen

Patent number: 5443798Abstract: A separator plate for a chemical oxygen generator candle includes an elongate rigid thermal insulating section; and at least a first conduit section on one side of the rigid section having a multiplicity of gas flow paths for conducting released oxygen from a burning candle longitudinally along the plate for increasing the burning action of the burning portion of the candle and pre-heating the unburned portion of the candle, and for retaining gas to act as a thermal insulator when the candle is not burning. A plurality of such plates are combined to form a separator assembly for surrounding a candle and a number of such separator assemblies are combined to form a multi-candle oxygen generator.Type: GrantFiled: October 27, 1993Date of Patent: August 22, 1995Assignee: The Charles Stark Draper LaboratoriesInventor: Peter Kerrebrock

Patent number: 5372617Abstract: A hydrogen generator for hydrolyzing hydrides substantially at stoichiometry to provide hydrogen on demand to a fuel cell is disclosed. The generator comprises a sealable, pressurizable, thermally insulated vessel into which a hydride in granular form is loaded. Water, most of which may be a byproduct from the fuel cell, is controllably introduced into the vessel for reaction with the hydride to generate hydrogen. The rate of introduction of the water is determined by the demand for hydrogen at the fuel cell. Heat transfer apparatus is disposed about the vessel to control the temperature of the reaction. A stirring mechanism is disposed in the vessel to prevent clumping of the hydride, to distribute the water to unreacted hydride, and to disperse the heat of the reaction throughout the hydride mass and thence to the heat transfer apparatus. An outlet from the vessel is provided for transfer of the generated hydrogen to the fuel cell.Type: GrantFiled: May 28, 1993Date of Patent: December 13, 1994Assignee: The Charles Stark Draper Laboratory, Inc.Inventors: Peter A.
