Patent number: 10772400Abstract: An improved umbrella holder. The improved umbrella member has a cylindrical member with an upper end and a bottom end. The upper end has a pair of arms extending from the rear surface of the cylindrical member to form a ring clamp. The ring clamp can be tightened to secure an umbrella inside of the cylindrical member. A slot is defined between the ring clamp and the cylindrical member to allow adjustment of the ring clamp independently from the cylindrical member.Type: GrantFiled: March 26, 2019Date of Patent: September 15, 2020Inventor: Timothy Booth

Publication number: 20180161918Abstract: Methods of and devices for forming edge chamfers and through holes and slots on a material that is machined using a laser, such as an ultrafast laser. The shaped material has predetermined and highly controllable geometric shape and/or surface morphology. Further, a method of and a device for preventing re-deposition of the particles on a material that is machined using a laser, such as an ultrafast laser. A fluid is used to wash off the particles generated during the laser machining process. The fluid can be in a non-neutral condition, with one or more chemical salts added, or a condition allowing the coagulation of the particles in the fluid, such that the particles can be precipitated to avoid the reattachment to the machined substrate.Type: ApplicationFiled: February 6, 2018Publication date: June 14, 2018Inventors: Ramanujapuram A.

Patent number: 8554037Abstract: A hybrid waveguide device includes a hollow core fiber having a core formed by a combination of solid material and gases. The hybrid nature of the core allows the hybrid device to transport a high energy high power laser beam having an ultra-short pulse width without damage to the hybrid device due to a higher tolerance of irradiance than single-matter cores. A waveguide device having a core with gases in addition to solid matter is characterized by a lower nonlinear refractive index coefficient (n2), lower numerical aperture, larger delivering laser beam size, and higher ionization potential of the gases. As a result, the hybrid waveguide fiber can transport ultra-short laser pulses having ablative energy levels and power levels, for example from a laser generating subassembly to a laser material-modification subassembly.Type: GrantFiled: September 30, 2010Date of Patent: October 8, 2013Assignee: Raydiance, Inc.Inventors: Xiang Peng, Michael Mielke, Timothy Booth

Publication number: 20080063340Abstract: Methods for optical isolation in high peak power fiber-optic systems prevent damage to a facet within a fiber-optic isolator caused by back-reflected light from, for example, an optical amplifier. Preventing damage to the facet may include expanding a mode area of the back-reflected light and/or reducing a change in refractive index.Type: ApplicationFiled: October 29, 2007Publication date: March 13, 2008Inventors: Timothy Booth, Ismail Yilmaz, James Brennan

Publication number: 20070064304Abstract: In an optical amplifier, passively wavelength-stabilized pump diodes generate pumping light to excite a gain medium (e.g., rare-earth-ion doped optical fiber or solid-state optical amplifier) near an absorption peak of the gain medium. The gain medium amplifies a pulsed laser signal coupled into the gain medium to a high peak power with minimal non-linear distortion. The gain medium may include a portion configured to receive the pumping light and another portion configured to amplify the pulsed laser signal. A volume phase hologram device may passively wavelength stabilize the pump diodes by reflecting a portion of the pumping light back to the pump diodes. Passively wavelength-stabilizing the pump diodes improves power efficiency of the optical amplifier.Type: ApplicationFiled: September 22, 2005Publication date: March 22, 2007Inventors: James Francis Brennan, Timothy Booth

Patent number: 6916271Abstract: A method and apparatus for controlling an amount of engagement of a clutch with a transmission. The method and apparatus includes selecting an engagement parameter, determining a desired operating parameter associated with the engagement parameter, and calibrating a control system to generate an engagement control signal to achieve the engagement parameter based on the desired operating parameter.Type: GrantFiled: August 7, 2003Date of Patent: July 12, 2005Assignee: Caterpillar IncInventors: Timothy A. Booth, David L. Zwetz, Gregory S. Hasler

Publication number: 20050134115Abstract: Methods and systems may provide theft protection in one or more work machines. Methods and systems may control one or more operational systems and may provide and manage varying levels of access to work machines. Methods and systems may react to override attempts in order to provide robust theft protection. One or more control modules embedded in a work machine may be leveraged to perform theft protection services. Methods and systems may activate a first control module to restrict access to a first operational system in a work machine and activate a second control module to restrict access to a second operational system in the work machine. The first control module may detect a substitution of a new control module for the second control module and automatically configure the new control module to restrict access to the second operational system in the work machine.Type: ApplicationFiled: December 23, 2003Publication date: June 23, 2005Inventors: Edward Betts, Timothy Booth, Roy Fonseca, Mark Hilbert, Daniel Swords, Nathan Taylor, David Zwetz

Patent number: 6786079Abstract: A recuperator core has a plurality of passages sealingly formed therein. In use, a fluid passes through a respective one of the plurality of passages under pressure. The recuperator core must be tested to determine an operational efficiency or leakage within the respective plurality of passages. A pair of sealing mechanisms are positioned at a respective one a pair of ends of the respective one of the plurality of passages.
