Patent number: 8897481Abstract: 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.Type: GrantFiled: February 20, 2013Date of Patent: November 25, 2014Assignee: Sound Sources Technology, Inc.Inventors: Yoichiro Sumitani, Chun-Yi Lin, Yu-Ling Cheng

Publication number: 20070110784Abstract: 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.Type: ApplicationFiled: May 3, 2004Publication date: May 17, 2007Applicant: RIMON THERAPEUTICS LTD.Inventors: Yu-Ling Cheng, Michael May, John Semple, Hai-Hui Lin
