A wireless device having an improved antenna system is disclosed comprising one or more antenna, preferably circularly polarized antenna, for transmitting or receiving a signal, and one or more floating ground planes, wherein the floating ground plane preferably is electrically isolated from and in sufficient proximity to the antenna so that it is inductively coupled to the antenna. The floating ground plane may comprise one or more of a strip, band, foil, plate, block, wire mesh, sheet or coating of conductive material and, for example, may be a relatively thin copper strip, band, foil or coating. The circularly polarized antenna, preferably comprises a flat planar shaped radiating element sized and configured to resonate at a predetermined, desired frequency, frequencies or band of frequencies, and a flat planar shaped antenna ground, both radiating element and antenna ground formed on the same printed circuit board. The radiating element is electrically isolated from the antenna ground but sufficiently close to resonate at the desired frequencies. Preferably the floating ground plane is larger than or more massive than the antenna ground, and preferably larger than or more massive than the radiating element. In a further embodiment the wireless device comprises a housing for interfacing with a user, the housing comprising a conductive contact exposed to the exterior of the housing and configured to be contacted by a user, wherein the conductive contact is electrically connected to the floating ground plane, preferably so that the user is coupled to the antenna and becomes part of the antenna system. The floating ground plane may also preferably be configured to substantially cover or overlap the antenna, and may also be configured to distribute and propagate the electromagnetic signals away from the head of the user.

A capacitive touch sensor includes a sensor substrate and an array of electrode elements formed over the sensor substrate. Each electrode element of the array includes at least one of a first electrode group comprising at least two drive electrodes and at least one sense electrode, or a second electrode group comprising at least two sense electrodes and at least one drive electrode. The respective electrodes of the first or second electrode group are arranged to form multiple capacitances over different coupling distances. A controller is operatively coupled to the array of electrode elements, the controller configured to determine a distance of an object relative to the surface of the touch sensor based on variations in the multiple capacitances.

Highly concentrated, water-based dispersions of certain lipophilic and/or hydrophobic antimicrobially active materials are stabilized to a surprising degree by a surfactant combination including a nonionic acrylic graft copolymer surfactant and a alkoxylated polyarylphenol phosphate ester surfactant. The active materials may be present in dispersion concentrates of the present invention singly or in useful combinations. The active materials are selected from the group of fungicides and bactericides consisting of 1,2-benzisothiazol-3(2H)-one; 2-octyl-2H-isothiazol-3-one; 5-chloro-2-methyl-2H-isothiazol-3 -one; 2-methyl-2H-isothiazol-3-one; pyrithione zinc; 3-iodo-2-propynyl butylcarbamate; 2-methylthio-4-ethylamino-6-tert-butylamino-s-triazine; and 3-(4-isopropylphenyl)-1,1-dimethylurea, and mixtures thereof. The dispersion concentrates may be efficiently shipped and stored, and subsequently diluted with water to produce less concentrated dispersions when desired. Even at relatively high concentrations, the dispersion compositions of the present invention can be stored for months or years without significant loss of stability.

Uses of the beta-glucan product as a food ingredient and for treating various diseases or disorders. The process includes the steps of forming flour from the cereal grain, mixing the flour with water to form a slurry of a process for obtaining beta-glucan from cereal grain including forming flour from the cereal grain, mixing the flour with water to form a slurry of an aqueous solution of beta-glucan and a solid residue, separating the aqueous solution from the solid residue, and removing water from the aqueous solution by evaporation or ultrafiltration or combinations thereof to form a beta-glucan containing gel or solid.

A pneumatic tire including a circumferential tread, two spaced apart beads, and sidewalls connecting said beads and tread, wherein said tire sidewall contains at least one internal annular sidewall insert including at least two annular segments, the at least two annular segments including first and second adjacent annular segments;

• • wherein said first and second annular segments are disposed with an interface therebetween;
  • wherein each of the at least two annular segments includes a rubber composition comprising at least one diene based rubber and at least one vulcanization modifier selected from the group consisting of α,ω-bis(N,N′-dihydrocarbylthiocarbamamoyldithio)alkanes, bismaleimides, and biscitraconimides; and

Spheroidal reconstituted HDL particles with a defined phospholipid composition have been formed for the first time. The spheroidal HDL particle are formed from discoidal HDL particles of defined phospholid composition to which is added in multiple stepwise format unesterified cholesterol carried in a solvent, followed by addition of a LCAT. Lysophopholipids are removed and a specific sequence of addition of reagents are found to be beneficial. Additionally it is found that a ratio of phospholipids to apoprotein A-1 of about 100:1 enhances the result.

An apparatus is provided for manufacturing a semiconductor package of the type in which a gap between a semiconductor chip and a mount board is filled with a resin. The apparatus includes resin supply means for supplying the resin along one side of the semiconductor chip, and resin supply control means for controlling the amount of resin supplied by the resin supply means such that more resin is supplied near the central portion of the semiconductor chip than near the end portions of the semiconductor chip. Also provided is a method that includes the steps of connecting the semiconductor chip and the mount board, and supplying the resin along one side of the semiconductor chip in such a manner that more resin is supplied near a central portion of the semiconductor chip than near the end portions of the semiconductor chip. According to the present invention, the resin is supplied such that it is relatively less concentrated near the peripheral portions of the chip so the resin spreads throughout the entire gap at substantially the same time as it flows along the peripheral portion of the chip. Thus, the formation of resin-less voids in the gap is deterred so that the grade and quality of the semiconductor device is improved.
