Patent number: 8556520Abstract: The invention relates to a sealing enclosure and a sealing assembly comprising the sealing enclosure and a mating enclosure as well as a method to connect both. The sealing enclosure loosely receives a connector within a connector volume so that the connector, which may be of a standard type used in electronic or optic data transmission, may be displaced within a plug face at the forward end of the connector volume. Thus, the connector may compensate variations in the position of a mating connector with respect to the mating enclosure. Moreover, the sealing enclosure allows to seal off the connector volume and engage the sealing enclosure with a mating enclosure in a single motion. This is affected by having a cable seal interposed between an inner body and an outer body. If the outer body is moved forward to engage the mating connector, the cable seal is squeezed between the cable and the inner body sealing off the connector volume at the rearward end of the inner body.Type: GrantFiled: September 28, 2010Date of Patent: October 15, 2013Assignee: Tyco Electronics Nederland BVInventors: Jacob Arie Elenbaas, Jarno Verhoeven

Patent number: 8475056Abstract: A fiber coupled semiconductor device having an improved optical stability with respect to temperature variation is disclosed. The stability improvement is achieved by placing the platform holding the semiconductor chip and the optical fiber onto a spacer mounted on a base. The spacer has an area smaller than the area of the platform, for mechanical decoupling of thermally induced deformation of the base from a deformation of the platform of the semiconductor device. Attaching the optical fiber to a vertical mounting surface of a fiber mount, and additionally attaching the fiber mount to a submount of the semiconductor chip further improves thermal stability of the packaged device.Type: GrantFiled: July 26, 2010Date of Patent: July 2, 2013Assignee: JDS Uniphase CorporationInventors: Prasad Yalamanchili, Xiangdong Qiu, Reddy Raju, Jay A.
