Abstract: An attachment assembly and method for attachment are provided. The attachment assembly includes a base having a shaft extending therefrom and a non-conductive compression member having a plurality of slots and configured to engage the shaft. The attachment assembly further includes a locking component configured to engage the shaft. The locking component has a plurality of resilient extensions configured to engage the plurality of slots of the compression member. The locking component is configured to compress the compression member in a tightened state and wherein the resilient extensions form a conductive path when in the tightened state.

Abstract: An attachment assembly, useful in quickly attaching an object to a panel, is provided with a base assembly having a shaft member extending therefrom and an expandable member having a plurality of fingers disposed on one side of the panel such that, during installation, the fingers radially outwardly expand to clamp the object to the panel. A process of mounting an object to a panel is also provided. The object is attached to the base of the attachment assembly and the shaft member is positioned in an aperture in a panel. The panel is clamped between the fingers and the base upon installation of the attachment assembly.

Abstract: A waterproof automotive antenna mounting assembly gasket comprises a base having a plurality of apertures and a mounting hole disposed therein, a generally sloped outer casing extending upward from the base, an inner casing connected along a bottom portion of the outer casing and positioned interior to the outer casing, a gap positioned between the bottom portion of the inner casing and the base, a plurality of compressible tabs extending inwardly from the inner casing and aligned with the apertures in the base, a channel disposed in between the inner and outer casings, a plurality of gripping members disposed on an underside of the base, a sealing interface disposed on the base, and an anti-rotation hole disposed on the base. The upper portion of the inner casing extends beyond the upper portion of the outer casing. The anti-rotation hole aligns with a corresponding hole attached to a secondary surface.

Abstract: A method for molding a thick part without significant surface distortion is disclosed. A cavity mold having a first core mold portion with strakes is used to create a first molded form having ribs proportioned and spaced apart to prevent distortions on one surface of the part due to shrinkage. A second core mold portion replaces the first core mold portion for creation of a second molded form having complementary ribs which are similarly proportioned to prevent distortions in an opposite surface of the part. The first form acts as a mold for the second form, the complementary ribs fuse together and form a homogeneous mass between the opposite surfaces of the part.

Abstract: The invention is directed to a flexible antenna comprising a plurality of strands of a nickel-titanium alloy, mountable on a base assembly of an antenna system, for transmitting signals from and receiving signals to said antenna. In one embodiment, the strands of nickel-titanium alloy may be configured as one or more selected from the group consisting of 7×1 and 9×3. A mast stud in the base assembly may be used for receiving a signal cable for communication with the antenna element. The assembly may also include a printed circuit board. A sleeve may be mounted over at least a portion of the antenna element and a radome mounted over at least a portion of the antenna element and the base assembly.

Abstract: An attachment assembly provides quick attachment of an automotive antenna unit or other object to the exterior of a vehicle. A single worker is able to install the antenna unit or other object with one downward push from the exterior without the need for tools. The attachment assembly also includes an anti-rotation feature to prevent rotation. The attachment assembly can only be removed from the interior, rendering the attachment assembly tamper resistant from the exterior. The attachment assembly can also be mounted on vehicles with various panel thicknesses.

Abstract: A microwave antenna and receiver assembly is described for use at gigaherz frequencies wherein the antenna is a microstrip antenna and the receiver includes a stripline filter circuit which is integrated in a layered configuration with both the microstrip antenna and the amplifier so as to achieve a very low noise figure, a low SWR and preserve good receiver characteristics, while being easily assembled inside a common radome housing. An inexpensive substrate material formed of alternating layers of polypropylene and woven glass is described for use with the microstrip antenna and other microwave structures.
