  • Inspection devices and related systems and methods
    Patent number: 10962506
    Abstract: Inspection devices include a nozzle portion having at least one opening and a transducer disposed in a rear chamber of a housing. The housing has at least one fluid channel defined in the housing and extending along at least a portion of the rear chamber. The at least one fluid channel is configured to supply a fluid into a forward chamber of the housing proximate the transducer. Related methods include operating an inspection device.
    Type: Grant
    Filed: May 6, 2019
    Date of Patent: March 30, 2021
    Assignee: Northrop Grumman Systems Corporation
    Inventors: Jeremy D. Palmer, Ronald G. Mellus, Edwin Dean S. Oba

  • Methods and devices for measuring volume resistivity
    Patent number: 7609073
    Abstract: A device for measuring the volume resistivity of materials and method of measuring are disclosed. The device for measuring has a receptacle of a known volume in which fluid materials, for example powdered or granular materials which may assume the shape of the receptacle, may be placed. The receptacle may have an insulating body and electrodes in the form of conductive end caps on either longitudinal end of the body. The resistance across the device, between the electrodes, may be measured. The volume resistivity of the fluid materials may be determined using the known volume of the receptacle and the resistance.
