Abstract: A biological and chemical decontamination device that includes at least one planar x ray source, an irradiation chamber that receive the x rays, and at least one access port on the irradiation chamber through which port articles can enter the irradiation chamber is described. The planar x-ray source includes a planar field emission cathode having a plurality of nanotubes, an electron target for receiving electrons from the cathode, and an applied voltage that accelerates electrons from the cathode to the target. The cathode can be formed into a variety of shapes as needed for specific applications.

Abstract: A repairable compact ultrasound probe which is easy to assemble and disassemble, and which has cable load transfer and heat dissipation capabilities. The transducer assembly of the probe has a heat-conductive backing board which is fastened to a yoke incorporated in the cable assembly. The cable assembly further has a strain relief element which is secured in a separate operation following attachment of the yoke to the backing board. When the strain relief element is secured, the probe handle is compressed between the strain relief and a headshell of the transducer assembly, thereby forming a housing. To disassemble the probe, the strain relief is turned counterclockwise with respect to the transducer, thereby releasing the handle and allowing access to the probe interior.
