Patent number: 9943698Abstract: In an embodiment, a method includes determining a target frequency corresponding to a target brain state and stimulating a brain of a user using feedback to attempt to achieve the target brain state in the user. The stimulating step may include measuring an electrical output of the brain of the user received from one or more sensors coupled to the user, determining a current frequency associated with the brain of the user based on the measured electrical output, and determining a difference between the current frequency and the target frequency. When the difference between the current frequency and the target frequency is greater than a predetermined amount, the method includes sending a signal to the brain of the user through one or more pathways. The signal may have a frequency operable to modify the current frequency associated with the brain of the user towards the target frequency.Type: GrantFiled: April 22, 2014Date of Patent: April 17, 2018Assignee: Lockheed Martin CorporationInventors: Charles J. Chase, Gerold Yonas

Patent number: 9913997Abstract: A device for monitoring gases present in a breathing mask. A gas sensing element carried by the breathing mask senses the partial pressure of a gas present in the breathing mask and outputs signals corresponding to the sensed gas partial pressure. The gas sensing element may comprise a gas-sensing material configured to emit, in response to light excitation, an optical signal at an intensity corresponding to the partial pressure of a sensed gas.Type: GrantFiled: July 23, 2013Date of Patent: March 13, 2018Assignee: Lockheed Martin CorporationInventors: Martin Anthony Kearney-Fischer, Sarah Kathleen Mottino, Charles J. Chase

Patent number: 8242404Abstract: A plasma jet system includes a housing with a single opening. A plasma generator is coupled to ionize a fluid in the housing. An electromagnetic accelerator is coupled to generate an electric field that accelerates ionized fluid in the housing toward the opening. A controller can modulate the frequency of the electric field to cause the ionized fluid to form a plasma vortex flow through the opening. A magnetic field is applied normal to the direction of the plasma vortex flow to mitigate the momentum of the electrons. The electrons slowed by the magnetic field can be collected and conducted to a location where they are re-inserted into the plasma vortex flow to maintain charge neutrality.Type: GrantFiled: December 15, 2010Date of Patent: August 14, 2012Assignee: Lockheed Martin CorporationInventors: Daniel N. Miller, Paul D. McClure, Charles J. Chase, Robert R. Boyd

Patent number: 8006939Abstract: A method to manipulate a fluid flow over a surface is provided. This method may be used to reduce drag, improve the lift to drag (L/D) ratio, attach fluid flow, or reduce flow noise at the surface. This involves flowing a fluid over the surface wherein the fluid contains positively charged ions and electrons. An electric field accelerates ions and electrons in directions parallel to the electric field. A magnetic field at the surface redirects ions and electrons based on their velocity and charge. The magnetic field imparts little force on the relatively heavy and slow moving positive ions but has a significant impact on the relatively fast moving, light weight electrons. This results in a non-zero net change in the total momentum of the positive ions and electrons allowing thrust to be realized. This thrust may be sufficient for vehicle propulsion or manipulation of the fluid flow around the vehicle.Type: GrantFiled: November 22, 2006Date of Patent: August 30, 2011Assignee: Lockheed Martin CorporationInventors: Paul D. McClure, Charles J. Chase

Patent number: 4888590Abstract: The invention is a reduced radar detectable runway. In detail, the invention comprises a runway having a plurality of holes randomly orientated and randomly dispersed across and along the surface thereof. The holes are preferably polygons, and ideally square in shape, and filled with a dielectric material. Additionally, the minimum necessary perimeter of the runway should include an extended portion in an irregular pattern about a least a portion of the necessary perimeter. This portion should also incorporate the randomly positioned and orientated holes.Type: GrantFiled: July 25, 1988Date of Patent: December 19, 1989Assignee: Lockhead CorporationInventor: Charles J.
