Deployable And Retractable Space Frame

US Patent:
7743576, Jun 29, 2010
Filed:
Feb 5, 2004
Appl. No.:
10/771935
Inventors:
Samuel Alan Johnson - Loveland CO, US
Assignee:
S.A. Robotics - Loveland CO
International Classification:
E04H 12/18
US Classification:
52646, 52645, 526481
Abstract:
A deployable and retractable space frame structure which requires no assembly, and can be either manually or automatically activated. It comprises rigid end rings or the like which attach to a multitude of spaced trusses of generally slender aspect ratio. The trusses are fabricated of two or more generally rigid, beam like strips which are hinged so as to become very flexible and non rigid when hinged strip elements lie planarly flattened, thus allowing the structure to collapse into a minimum volume state. In this configuration truss beams assume a curvature approximating the curvature of the structure end rings. Upon deployment, the truss beams become straight, and hinged beam-like strips fold to create a triangular cross sectional moment of inertia to become very rigid and straight. The structure is deployable and stow-able an infinite number of times, and is suitable for a wide variety of applications including telescope structures, portable building and antennae masts, planetary vehicles, space stations, and the like.

High Pressure Cleaning And Decontamination System

US Patent:
7140954, Nov 28, 2006
Filed:
Oct 21, 2004
Appl. No.:
10/970214
Inventors:
Samuel A. Johnson - Loveland CO, US
Joseph E. Dixon - Fort Collins CO, US
Assignee:
S. A Robotics - Loveland CO
International Classification:
B24C 3/00
US Classification:
451 75, 451 99
Abstract:
Abrasive cleaning and decontamination methods and systems are disclosed. The methods and systems use a high pressure liquefied gas, such as carbon dioxide, which produces insignificant quantities of secondary waste. These principles of the invention exploit the properties of the relatively high triple point of COin order to first pressurize it to 35,000 to 60,000 PSI from a pressurized liquid. In the pressurized state, such a fluid can be at or above room temperature, allowing for transport over long distances in a flexible high pressure hose. At a point of use, a heat exchanger may subsequently chill the liquid, so that after expansion through a small high pressure orifice, a significant fraction of the liquid is converted to solid phase crystals exiting at high velocity to effectively clean and decontaminate. For more aggressive cleaning, abrasive particles and/or small diameter solid COpellets can be entrained into the high pressure COslipstream.

US Patent:
7631834, Dec 15, 2009
Filed:
Apr 19, 2007
Appl. No.:
11/737591
Inventors:
Samuel Alan Johnson - Loveland CO, US
William Dennis Burkard - Longmont CO, US
David Anthony Norman - Greenville TX, US
Assignee:
Stealth Robotics, LLC - Longmont CO
International Classification:
B64C 27/08, B64C 29/00, B64C 39/00, B64C 27/00
US Classification:
244 1717, 244 31, 244 1711, 244 1719, 244 1721, 244 1723, 244 751, 244 76 R, 244175
Abstract:
This disclosure involves aerial robots that dispenses conductive filament or systems, methods, and software for support such aerial robots. One remotely powered aerial robot system includes an aerial robot and a power source. The aerial robot comprises a body, a first propeller coupled to the body and operable to provide thrust to the aerial robot, a rotatable spool coupled to the body, and a conductive filament that is dispensed from the spool by rotation of the spool is one direction and retrieved by rotation of the spool in another direction. The power source is coupled with, and remote from, the aerial robot via the conductive filament, where the conductive filament is operable to power the first propeller using power from the power source.

Method And Apparatuses To Remove Slag

US Patent:
7204208, Apr 17, 2007
Filed:
Jun 17, 2003
Appl. No.:
10/464362
Inventors:
Samuel A. Johnson - Loveland CO, US
Daniel S. Johnson - Loveland CO, US
Assignee:
S.A. Robotics - Loveland CO
International Classification:
F22B 37/20
US Classification:
122379, 134167 R, 153161
Abstract:
A robotic apparatus for the cleaning and maintenance of coal fired boilers, which is designed to operate in the high temperature environment of the combustion gasses to effectively clean and remove slag deposits of the boiler heat transfer surfaces by use of a precision directed, low pressure, low flow rate water stream. The robotic cleaning apparatus is comprised of lightweight carbon fiber structural elements, attached to the exterior of the boiler, and cooled by annular pressurized water sheaths impingent on a thin metal skin covering the lightweight structural elements. Multiple articulated joints allow for complete access to the heat transfer surfaces of the boiler. A variety of payloads can be delivered to specific points within the boiler, including imaging systems, cutting, and welding apparatuses. A mathematical state space control matrix allows for optimal positioning and feedback control of motions.

Composite Fluid Actuated Cylinder

US Patent:
7185581, Mar 6, 2007
Filed:
Jul 26, 2004
Appl. No.:
10/899342
Inventors:
Samuel A. Johnson - Loveland CO, US
Assignee:
S.A. Robotics - Loveland CO
International Classification:
F16J 10/00
US Classification:
921692, 92223
Abstract:
A fluid actuator having a honed metallic sleeved inner liner assembled with fitted end caps. The inner liner and end caps are wound with carbon reinforced fiber filaments in both longitudinal and hoop orientations so as to withstand increased fluid pressure over traditional metallic designs. The fluid actuator of the present invention is lightweight and had an extremely stiff piston and rod assembly, which may also be fabricated from high flexural modulus composite materials so as to allow for a very stiff, lightweight, hydraulic cylinder which is particularly resistant to column buckling at long extensions and comprises an economical, non-rebuildable design.

Imaging Based Stabilization

US Patent:
2012024, Oct 4, 2012
Filed:
Apr 4, 2011
Appl. No.:
13/079106
Inventors:
Samuel A. Johnson - Loveland CO, US
Helen Greiner - Wayland MA, US
Andrew Shein - Winchester MA, US
Assignee:
CyPhy Works, Inc. - Danvers MA
International Classification:
H04N 7/18
US Classification:
348113, 348136, 348E07085
Abstract:
An image-based sensor system for a mobile unit makes use of light emitters and imagers to acquire illumination patterns of emitted light impinging on the floor and/or walls surrounding the unit. The illumination pattern is used to estimate location and/or orientation of the unit. These estimates are used for one or more functions of stabilization, calibration, localization, and mapping of or with respect to the unit.

Aerial Robot

US Patent:
7510142, Mar 31, 2009
Filed:
Feb 24, 2006
Appl. No.:
11/361122
Inventors:
Samuel A. Johnson - Loveland CO, US
Assignee:
Stealth Robotics - Longmont CO
International Classification:
B64C 27/08, B64C 29/00, B64C 39/00, B64C 27/00
US Classification:
244 1717, 244 31, 244 1711, 244 1719, 244 1721, 244 1723, 244 751, 244 76 R, 244175
Abstract:
An aerial robot is disclosed. The aerial robot may include at least one pair of counter-rotating blades or propellers, which may be contained within a circumferential shroud or a duct. In one embodiment, the aerial robot may have the ability to hover and move indefinitely. Electric power to the robot may be provided by a tether or an on-board power supply. In tethered embodiments, a solid-state, electronic voltage transformer may be used to reduce a high voltage, low current source to lower voltage, higher current source. In one embodiment, secure data communication between a ground unit and the aerial robot is facilitated by impressing high bandwidth serial data onto the high voltage tether wires or a thin optical fiber which is co-aligned with the tether wires. In one embodiment, precise navigational and position controls, even under extreme wind loads, are facilitated by an on-board GPS unit and optical digital signal processors. In one embodiment, if the tether detaches, precision free-flight is possible with on-board batteries.
