Abstract: A grille attachment for a loudspeaker is disclosed. A grille retainer is defined by a retention lip portion, a radial rim interface portion, and a hinge portion. The radial rim interface portion is in an abutting relationship with a flange radial mounting surface of the loudspeaker basket. The hinge portion connects the retention lip portion and the radial rim interface portion. The retention lip portion extends toward a flanged rim of the speaker basket, and defines an inner retention surface that is opposed to a flange circumferential surface. A grille extends across the griller retainer and is defined by a grille body and a grille rim that is circumferentially disposed and extending from the grille body. The grille rim is interposed between the flange circumferential surface and the inner retention surface, with the retention lip portion exerting a radial compressive force against the grille rim.

Abstract: The invention relates to the use of a thermal reversible gel, such as a copolymer composition, as a biological filler or implant. The gel has a semi-solid form at body temperature, but upon cooling to a temperature below a threshold level, the gel is liquefied and can be re-shaped, re-sized, manipulated or removed from the body. The gel may be used as a subcutaneous implant, a biological filler, joint or tissue spacer, for wrinkle filling or other cosmetic implants, as a soft-tissue replacement for reconstructive surgery, or as a barrier within the lumen of a biological structure, such as a blood vessel. The implant may be used to provide reversible birth control by providing, for example, a reversible barrier to the cervix or a reversible blockage of the lumen of the vas deferens.

Abstract: The invention relates to a gelable copolymer composition comprising a copolymer in a solvent. The copolymer has the structure A(B)n, wherein the core (A) is soluble in the solvent, the arms (B) are convertible between soluble and insoluble in the solent depending on an environmental condition, and n>1. The composition forms a gel under environmental conditions in which B is insoluble, through formation of B aggregates. Block copolymers comprising polyethylene glycol (PEG) and poly(N-iso-propylacrylamide) (PNIPAAm) having a liquid form at ambient temperature under aqueous conditions and a gel form at body temperature are disclosed.
