US Classification:

343702, 343895, 343901

Abstract:

A telescoping antenna ( ) has a mast element ( ) with first and second ends ( ), the first end ( ) being mounted on a cellular telephone housing ( ) and establishing electrical connection with signal processing circuitry ( ) within the cellular telephone ( ). The telescoping antenna ( ) also has a cylindrical radiating element ( ) that slidably engages the mast element ( ). In a retracted or stowed position first ends ( ) of the mast element ( ) and the cylindrical radiating element ( ) are substantially adjacent, and second ends ( ) of the mast element ( ) and the cylindrical radiating element ( ) are also substantially adjacent. A loading coil ( ) has a first end ( ) permanently connected to the second end ( ) of the cylindrical radiating element ( ) and has a second end ( ) engageable with the second end ( ) of the mast element ( ). The loading coil ( ) engages the mast element ( ) when the antenna ( ) is in a stowed position, and is disconnected from the mast element ( ) when the antenna ( ) is in the deployed position. The antenna ( ) provides a substantially constant frequency of operation in both an extended and retracted orientation.

International Classification:

H04Q 7/20

US Classification:

4555755, 455274, 343702

Abstract:

A dual-band cellular telephone antenna. A monopole antenna is tuned to a first resonant frequency of operation. A first helical antenna is coupled to the monopole antenna and has turns surrounding the monopole antenna, where the first helical antenna is tuned to a second resonant frequency of operation. A grounded second helical antenna surrounds the first helical antenna and is formed to have an upper capacitive loading segment to tune the grounded second helical antenna at substantially the second resonant frequency of operation. The cellular telephone has a housing formed of a conductive material. A printed circuit board (PCB) has a metalized ground plane, wherein the metalized ground plane and the grounded second helical antenna are coupled to the cellular telephone housing.

A01N 43/04
C07J 71/00

US Classification:

514172, 514 27, 540 17

Abstract:

The present invention is based on the discovery that certain chemical compounds isolated from Chinese medicinal herbs are useful as anti-microbial agents, e. g. , anti-bacterial agents, anti-fungal agents, and the like. In particular, the present invention provides compositions useful for treating microbial infections such as, for example, oral microbial infections, including periodontal disease and dental caries.

International Classification:

A61K039/09

US Classification:

424/185100, 424/244100

Abstract:

Dental caries in man may be prevented or treated by oral ingestion of human or humanized murine monoclonal IgG and IgM antibodies that bind to surface antigens of cariogenic organisms, such as . The genetically engineered monoclonal antibodies engage the effector apparatus of the human immune system when they bind to cariogenic organisms, resulting in their destruction. In a preferred embodiment, monoclonal antibodies to cariogenic organisms are produced by edible plants, including fruits and vegetables, transformed by DNA sequences that code on expression for the desired antibodies. The antibodies are applied by eating the plants.

Abstract:

Microbial infection may be treated by administration of a fusion protein comprising one or more recognition sequences and at least one antimicrobial peptide. In preferred embodiments, a linker peptide connects the recognition sequence and one or more antimicrobial peptides. The recognition sequence may be an immunoglobulin molecule, or fragment thereof, that specifically binds to a target antigen present on a pathogen. The recognition sequence may also be a non-immunological polypeptide, providing that the polypeptide binds specifically to a particular ligand. In presently preferred embodiments the recognition sequence is monoclonal antibody that binds specifically to and the antimicrobial peptides are derivatives of histatin.
