Patent number: 11578928Abstract: A transducer system includes a housing, an electromechanical transducer within the housing, a wicking material adjacent to a portion of the electromechanical transducer, and a coolant solution within the housing. The coolant solution transitions from a liquid phase to a gaseous phase in response to a temperature of the electromechanical transducer exceeding a threshold temperature. In some example cases, the coolant solution has a boiling point of less than about 60° C., which effectively defines the threshold temperature. The coolant solution may be chosen such that it remains a liquid during a first phase (cooling via conduction), and then evaporates during a second phase (cooling via conduction and convection) as the electromechanical transducer heats up.Type: GrantFiled: February 13, 2019Date of Patent: February 14, 2023Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Charles P.

Patent number: 11574391Abstract: Local detail enhancement (LDE) is an imagery contrast enhancement method applied to visible and uncooled long wave imagery. It enhances local spatial detail through the use of a median based high/band pass filter. The generated detail channel is blended with a histogram-equalized version of the image, creating an image that contains both local detail as well as retaining some amount of global intensity. Retaining global intensity coherency allows for easier target acquisition when compared to fully local forms of contrast enhancement.Type: GrantFiled: June 16, 2021Date of Patent: February 7, 2023Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Derek T.
