Patent number: 10788384Abstract: A method, apparatus, and system to quantify tension forces of the anchor bolts for, e.g., SLTS support structures. A sensing assembly comprising one or more washers is installed along an anchor bolt. The sensing assembly comprises two spaced-apart surfaces between which a capacitance can be measured if electrical potential is created between the surfaces. The capacitance between the surfaces can be calibrated to bolt tension based on the relative distance between the surfaces. An RFRD circuit is connected to the two surfaces. An RF interrogation signal can supply the electrical potential and allow a reading of the responsive capacitance between surfaces to convert the capacitance reading into a bolt tension. Additionally, the introduction of the battery-free RFRD allows data to be acquired wirelessly from a distance, enabling an entirely new method of inspection. With minimum additional hardware cost, it provides a cost-effective way to replace traditional bolt installation and inspection methods.Type: GrantFiled: January 31, 2018Date of Patent: September 29, 2020Assignee: Iowa State University Research Foundation, Inc.Inventors: An Chen, Daji Qiao, Long Que

Patent number: 9728703Abstract: Apparatus and methods of generating electricity include using an optically and thermally responsive material comprising single-walled Carbon nanotubes and Copper sulfide nanoparticles. This material acts as a thermoelectric generator lacking rectifying effects. In some forms, the generator may generate electricity from a light source alone, a heat source alone, or a source of both light and heat. Some forms exhibit enhanced optical and thermal switching characteristics, light absorption, photocurrent and thermocurrent generation under light illumination or/and thermal radiation, providing a new route to obtain thermoelectricity without any cooling or heat-sink component. Moreover, measurements showed thin films of SWNT CuS NPs had significantly increased light absorption (up to 80%) compared to untreated SWNT thin films.Type: GrantFiled: March 11, 2014Date of Patent: August 8, 2017Assignees: Louisiana Tech Research Corporation, Board of Regents, The University of Texas SystemInventors: Long Que, Wei Chen

Patent number: 8901802Abstract: An energy harvesting device capable of harvesting multiple forms of energy. The device includes a base, a piezoelectric cantilever, and a carbon nanotube film. The piezoelectric cantilever includes a piezoelectric layer disposed between a top electrode and a bottom electrode. A proximate end of the piezoelectric cantilever is supported by the base. The base does not support a distal end of the piezoelectric cantilever. The piezoelectric cantilever is capable of converting vibration energy into electrical power. The carbon nanotube film is capable of absorbing electromagnetic radiation and thermal radiation, and thereafter transmitting heat to the piezoelectric layer. The piezoelectric layer is mechanically deformed in response to said heating, thereby generating electrical power.Type: GrantFiled: April 13, 2011Date of Patent: December 2, 2014Assignee: Louisiana Tech University Research Foundation, a division of Louisiana Tech University Foundation Inc.Inventor: Long Que
