Patent number: 9080821Abstract: A heat dissipation system that includes a structure having a surface with a cavity recessed on the surface. A wing or channel causes a vortex to occur in the cavity. Destabilizers, such as projections or recesses are disposed on the sidewall of the cavity to disrupt the local surface boundary layer that forms in the cavity. Alternatively, a plurality of freely moving bead elements are disposed in the cavity to disrupt the local surface boundary layer. A cover can be included that prevents the bead elements from exiting the cavity.Type: GrantFiled: March 19, 2015Date of Patent: July 14, 2015Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Yan R. Kucherov, Graham K. Hubler

Publication number: 20140305293Abstract: A composite armor plate includes a fracture layer placed adjacent to a ceramic layer. The ceramic layer provides a ballistic resistant layer that receives a ballistic impact and propagates a compression wave. The fracture layer is placed behind the ceramic layer and absorbs a portion of the compression wave propagating out in front of the ballistic impact. The absorbed compression wave causes the fracture layer to at least partially disintegrate into fine particles, which dissipates energy in the process. To cause a higher degree of fracturing (and thus larger dissipation of compression wave energy) the fracture layer includes a plurality of resonators embedded in a fracture material.Type: ApplicationFiled: February 20, 2014Publication date: October 16, 2014Applicant: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Yan R. Kucherov, Graham K. Hubler, Brant Johnson

Publication number: 20140060300Abstract: A system for reducing the effects of a blast wave includes armor plating configured to face a supersonic blast wave. The armor plating has a surface consisting of alternating tall and short peaks with valleys between the peaks. The peaks and valleys are positioned such that the supersonic blast wave reflects from the side surfaces of the tall peaks as a regular reflection that at least partially suppresses Mach reflection of the supersonic wave caused by the short peaks and the valleys. The surface may also be designed to not trap reflected waves. The valleys can be parabolic shaped to deflect and/or dissipate transonic flow that follows the blast wave front.Type: ApplicationFiled: May 4, 2009Publication date: March 6, 2014Applicant: Nova Research, Inc.Inventors: Yan R. Kucherov, Graham K. Hubler

Patent number: 8176831Abstract: An armor plate transforms projectile energy into solid-state lattice waves and facilitates absorption of these waves at different wavelengths. For high frequency lattice waves, dopants are used for absorbing the lattice waves and converting them to thermal energy. Heavy dopants and layered materials can also be use for reflecting lattice waves to facilitate attenuation through absorption. A spreading layer can also be used for dispersing non-absorbed lattice waves.Type: GrantFiled: April 10, 2009Date of Patent: May 15, 2012Assignees: Nova Research, Inc., The United States of America, as represented by the Secretary of the NavyInventors: Yan R.

Patent number: 7569763Abstract: A solid-state energy converter with a semiconductor or semiconductor-metal implementation is provided for conversion of thermal energy to electric energy, or electric energy to refrigeration. In n-type heat-to-electricity embodiments, a highly doped n* emitter region made of a metal or semiconductor injects carriers into an n-type gap region. A p-type layer is positioned between the emitter region and gap region, allowing for discontinuity of corresponding Fermi-levels and forming a potential barrier to sort electrons by energy. Additional p-type layers can optionally be formed on the collector side of the converter. One type of these layers with higher carrier concentration (p*) serves as a blocking layer at the cold side of the converter, and another layer (p**) with carrier concentration close to the gap reduces a thermoelectric back flow component. Ohmic contacts on both sides of the device close the electrical circuit through an external load to convert heat to electricity.Type: GrantFiled: September 13, 2006Date of Patent: August 4, 2009Assignee: Micropower Global LimitedInventors: Yan R.

Patent number: 6946596Abstract: Tunneling-effect converters of thermal energy to electricity with an emitter and a collector separated from each other by a distance that is comparable to atomic dimensions and where tunneling effect plays an important role in the charge movement from the emitter to the collector across the gap separating such emitter and collector. At least one of the emitter and collector structures includes a flexible structure. Tunneling-effect converters include devices that convert thermal energy to electrical energy and devices that provide refrigeration when electric power is supplied to such devices.Type: GrantFiled: September 13, 2002Date of Patent: September 20, 2005Inventors: Yan R.

Patent number: 6906449Abstract: The present invention embodies a solid state thermionic energy converter and is directed to a method and apparatus for conversion of thermal energy to electrical energy, and electrical energy to refrigeration. The present invention maintains a thermal separation between an emitter and a collector through a fractional surface contact of decreasing cross-sectional area towards the point of contact. The fractional surface contacts may be associated with the emitter, a barrier, or the collector. Maintaining a thermal separation between the emitter and the collector provides for ballistic electron transport through the barrier and reduces the transport of electrons through thermal conductivity. Hence, the efficiency is increased through the collection of ballistic electrons and the reduction of thermal conductivity electrons which cannot be collected. The inventive principle works for hole conductivity, as well as for electrons.Type: GrantFiled: November 27, 2002Date of Patent: June 14, 2005Assignee: C.P. Baker Securities, Inc.Inventors: Yan R.

Patent number: 6779347Abstract: Solid state thermioninc refrigerators with elements having at least one barrier segment connected to wire-equivalent segments. The barrier segment has solid state regions that establish a potential energy barrier to electric carriers. This barrier is such that the circulation of a negative electrical charge from one of such regions to another region experiences an increasing potential energy. Elements can be superconducting or nonsuperconducting. Elements can also include an inverse barrier.Type: GrantFiled: May 13, 2002Date of Patent: August 24, 2004Assignee: C.P.
