The housing has a peripheral portion (120) that projects forward of the ferrule front tips to protect them even though they project forward of the housing front surface. The alignment sleeve has a short length (A) that is about three times its inside diameter (C), and a long spring (84) is used to bias the terminus forwardly and maintain a substantially constant forward force on the terminus, the spring having an initial length (B) which is at least 150% of the alignment sleeve length. A plug (96) that holds the alignment sleeve in place, has an internal bore with a rear bore portion (154) that receives the front end of the terminus body (90). A retainer (100) includes a clip holder (102) with a holder rear portion (172) surrounded by the spring.

A method for uplink synchronization of a first transceiver and a second transceiver in a multi-user cellular communication system having communication resources divided into communication channels. The method includes the following steps. A first signature sequence is transmitted from the second transceiver to the first transceiver, where the signature sequence is selected from a first set of signature sequences. In the first transceiver, the received signal is correlated with at least one signature sequence from a second set of signature sequences to estimate the time of arrival of the signature sequence to synchronize transmission between the second transceiver and the first transceiver. In transmitting the first signature sequence from the second transceiver to the first transceiver, the first signature sequence constitutes at least part of a zero-correlation zone sequence.

A multi-stage inertial switch including: a housing having a first electrical contact; two or more members disposed in the housing, at least one end of each of the two or more members being sequentially movable upon a different level of acceleration of the housing; and a movable member movable within the housing by the sequential movement of the two or more members, the movable member having a second electrical contact capable of engagement with the first electrical contact to one of open or close an electrical circuit between the first and second electrical contacts upon an occurrence of a predetermined magnitude and/or duration acceleration event.

A method for friction-stir-welding two hollow workpieces. While open end portions of the workpieces butt each other, and an annular support member supports the butt end portions from the inside, the workpieces are joined together by friction stir welding. An annular, radially outward projection is formed on the entire outer circumferential surface of the support member in an intermediate region along the support member width. Support portions to be fitted into corresponding end portions of the workpieces for support from the inside are formed on the support member at corresponding opposite sides of the annular, radially outward projection. While the support portions are fitted into the workpieces, respectively, and end faces of the workpieces abut the annular, radially outward projection, the butt end portions of the workpieces and the support member are friction stir welded from the outside. Thereby, the hollow workpieces are welded without joint defect.
