Abstract: There is provided an antenna reflector including at least first and second reflector segments, each having first and second sides. The first and second reflector segments being configured to be connected together wherein the first sides of the first and second reflector segments define a substantially continuous surface of an antenna reflector. A first latch member is attached to the second side of the first reflector segment and a second latch member is attached to the second side of the second reflector segment. Each latch member includes an abutting surface which contacts one another when the first and second reflector segments are connected together. At least one protrusion extends from the abutting surface of the first latch member. There is at least one recess in the abutting surface of the second latch member. The protrusion is received in the recess when the respective abutting surfaces contact one another.

Abstract: Systems and methods to obtain an ultrasonic image of a large detection area are disclosed. A system includes a source of ultrasound generating ultrasonic energy and projecting the ultrasonic energy from a projecting end and an adapter interfaced to the projecting end and ultrasonically coupling the source of ultrasound to a first surface of the structure to be imaged at an adjustable angle of incidence. A method includes ultrasonically coupling a source of ultrasonic energy to a first surface of a structure to be imaged with an adapter, the adapter adjustable to a select a first angle of incidence and a second angle of incidence, projecting ultrasonic energy into the structure, and detecting a reflected acoustic energy from the structure with an ultrasound camera. A first angle of incidence is selected to introduce a longitudinal wave into the structure, and a second angle of incidence is selected to introduce a shear wave into the structure.

Abstract: An ultrasonic imaging apparatus combined with an x-ray imaging apparatus and/or an additional ultrasonic imaging apparatus performs ultrasonic sonography and/or x-ray imaging or multiple ultrasonic sonography to produce imagery that are spatially correlated. A holding means holds an object to be imaged in compression in an examination area. The x-ray source and the ultrasonic source are each relocatable from an inactive imaging position to an inactive non-imaging position. The x-ray image and ultrasonic sonography image are both taken in transmission and the resulting images contain a registry object to assist a user in spatially correlating the images. The speckle contained in the sonography image is reduced allowing for higher resolution of abnormalities in the tissue and improved concurrent biopsy procedures.

Abstract: A compact, foldable tripod structure is self contained and mounts an antenna reflector. The structure comprises an assemblage of structural members which are long and slender, arranged to be folded into a compact configuration for storage or transport, and adapted to be rapidly unfolded at a desired site to produce an antenna support structure having great rigidity. The geometry of the structure is designed so that most components are in tension or compression, thereby resulting in a high strength/deflection-to-weight ratio which renders the structure inherently stable. Components are permanently attached to the structure and rapid erection may be completed manually.
