US Classification:

342361, 343771

Abstract:

A dual-polarization common aperture antenna having fully populated common aperture dual polarized arrays. The inventive antenna includes a first and second arrays of radiating slots disposed in a faceplate. The second array is generally orthogonal and therefor cross-polarized relative to the first array. The first array is waveguide fed and the second array is stripline fed. In the illustrative implementation, the first array and the second array share a common aperture. The common aperture is fully populated and each array uses the aperture in its entirety. The first and second arrays of slots are arranged for four-way symmetry. Each slot in the first array is a vertically oriented, iris-excited shunt slot fed by a rectangular waveguide and centered on a broad wall thereof. The second array is a standing wave array in which each slot is an air cavity backed slot fed by an inverted micro-stripline offset from a center thereof.

Abstract:

The invention provides an all-in-one golf belt for attaching objects. In an embodiment, the all-in-all golf belt includes: a flat strip having inner and outer surfaces, which is configured to be disposed around a portion of a golfer's body; fasteners provided on the outer surface of the flat strip, one or more of the fasteners being configured to engage at least one of the objects; and holding portions provided in each of the objects, each of the holding portions being configured to hold a portion of at least one of the fasteners. The holding portions of the objects are configured to hold the at least one of the fasteners with force of a predetermined magnitude. The fasteners may include hook-and-loop fasteners and magnets. The objects may be a glove, a ball marker, a ball mark repair tool, and a golf ball pouch.

International Classification:

A61C 5/09
A61C 5/10

US Classification:

4332221, 433223

Abstract:

A coping material for a prosthetic crown is provided. The coping material according to current application is comprised of two portions which are mechanically bonded each other. The first portion is the main coping portion that is located beneath of the enamel layer of a crown. The first portion is made from, including but not limited to, common metal and/or portion fused gold (PFG). The second is the portion which makes contact with gum tissue. That portion surrounds the brim of the bottom of the coping for 360 degrees. The gum contacting portion is comprised of bio-gold that is mechanically bonded to the main coping portion. Centrifuging of molten bio-gold technology is applied for mechanical bonding of the two portions. Electronic forming technology is also applied for mechanical bonding.

US Classification:

343771

Abstract:

Disclosed is a common aperture dual polarization antenna array (30). This common aperture dual polarization antenna array (30) includes an antenna aperture (36) and a plurality of centered slot arrays (32) positioned within the antenna aperture (36). A plurality of notch dipole arrays (34) are positioned within the antenna aperture (36) and positioned substantially orthogonal to the plurality of centered slot arrays (32). A first feed guide (46) is coupled to the plurality of centered slot arrays (32) and a second feed guide (56) is coupled to the plurality of notch dipole arrays (34).

Abstract:

A radiator (10) comprising one or more centered longitudinal shunt slots (12) disposed in a rectangular waveguide (11) that are fed by corresponding offset ridge resonant irises (14). The offset ridge resonant irises that are centered on each respective slot. When multiple slots and offset ridge resonant irises are employed, adjacent irises are oriented opposite to one another.
