Patent number: 10734565Abstract: An electric generator device is provided that includes a thermoelectric array, a base plate, and an electric power output. The thermoelectric array may include a hot side portion and a cold side portion. The base plate may be configured to receive heat from a heat source to be transferred to the hot side portion of the thermoelectric array. The electric power output may be electrically coupled to the thermoelectric array. The thermoelectric array may be configured to convert a temperature differential into an electric voltage for output to the electric power output. The power generation housing may be configured to hold a heat rejection substance that absorbs heat from the cold side portion of the thermoelectric array to facilitate generation of the temperature differential between the hot side portion and the cold side portion of the thermoelectric array.Type: GrantFiled: December 22, 2017Date of Patent: August 4, 2020Assignee: The Johns Hopkins UniversityInventors: Jonathan M. Pierce, Rama Venkatasubramanian, Geza Dezsi, Drew P. Seker, Craig B. Leese

Patent number: 9281537Abstract: A thin film electrode is fabricated from a non-metallic, non-conductive porous support structure having pores with micrometer-range diameters. The support may include a polymer film. A first surface of the support is metalized, and the pores are partially metallized to create metal tubes having a thickness within a range of 50 to 150 nanometers, in contact with the metal layer. An active material is disposed within metalized portions of the pores. An electrolyte is disposed within non-metalized portions of the pores. Active materials may be selected to create an anode and a cathode. Non-metalized surfaces of the anode and cathode may be contacted to one another to form a battery cell, with the non-metalized electrolyte-containing portions of the anode facing the electrolyte-containing portions of the cathode pores. A battery cell may be fabricated as, for example, a nickel-zinc battery cell.Type: GrantFiled: July 22, 2013Date of Patent: March 8, 2016Assignee: The Johns Hopkins UniversityInventors: Rengaswamy Srinivasan, Jeffrey P. Maranchi, Lance M. Baird, Ryan M. Deacon, Arthur S. Francomacaro, Paul J. Biermann, Craig B. Leese, Gary E. Peck

Patent number: 9011158Abstract: A human surrogate neck model includes a spinal neck region containing cervical vertebrae. A biosimulant intervertebral material is inserted between the cervical vertebrae. The spinal neck region is surrounded by a first silicone material mixed with a polymeric cross-linking inhibitor. One or more elastic tension bands are anchored to a top interface and a bottom interface of the neck model. A second silicone material mixed with a polymeric cross-linking inhibitor is applied to surround the spinal neck region and the first silicone material and to embed the tension bands. One or more of the elastic tension bands and/or a concentration ratio of the first silicone material or second silicone material to the polymeric cross-linking inhibitor can be adjusted for variable test conditions to closely simulate or mimic the static and dynamic characteristics of a human neck in various scenarios.Type: GrantFiled: February 7, 2013Date of Patent: April 21, 2015Assignee: The Johns Hopkins UniversityInventors: Andrew C. Merkle, Jack C. Roberts, Ian D. Wing, Liming M. Voo, Craig B. Leese, Howard A. Conner

Patent number: 8725449Abstract: A human surrogate head model (HSHM) to measure brain/skull displacement due to a physical force, such as due to an explosive, ballistic, or automotive crash type of event. A HSHM may include a plurality of magnetic field generators positioned stationary relative to a HSHM skull, each to generate a magnetic field oriented with respect to a corresponding one of multiple directions. The HSHM may include one or more electromagnetic force (EMF)-based displacement sensors, each of which may include three inductive coils oriented orthogonally with respect to one another and co-aligned about a central point. A signal processor may be implemented to separate signals generated by each coil of each EMF-based displacement sensor into a plurality of component magnitudes, each attributable to a corresponding one of the magnetic fields. A computer-implemented model may be implemented to correlate between the component magnitudes and a corresponding position and orientation of the displacement sensor.Type: GrantFiled: June 24, 2011Date of Patent: May 13, 2014Assignee: The Johns Hopkins UniversityInventors: Jack C. Roberts, Andrew C. Merkle, Bliss G. Carkhuff, Ian D. Wing, Craig B. Leese

Patent number: 8679583Abstract: A method of making an antifouling article includes providing a mold having a mold cavity and a mold surface for defining an article. The method also includes applying a mold release material to the mold surface. The method further includes coating the mold surface with a plurality of metallic powder particles comprising an antifouling agent. Still further, the method includes filling the mold with a curable polymeric material. Yet further, the method includes curing the polymeric material and forming an article having a surface defined by the mold surface, the surface of the article having the plurality of metallic powder particles disposed thereon and comprising an antifouling coating.Type: GrantFiled: August 29, 2012Date of Patent: March 25, 2014Assignee: The Johns Hopkins UniversityInventors: Charles W. Kerechanin, II, Justin S. Morrison, Craig B. Leese, Paul J. Biermann, Ryan J. Forrest, William R. Setzler
