Abstract: An antipersonnel barrier system is disclosed which includes at least one concertina coil and a plurality of spaced support members. Each of the support members includes a base section and a vertical section. Each of the concertina coils is secured to the support members to provide a horizontally and vertically stabilized barrier. A length limiting cable is provided to limit the length of spacing between adjacent support members. The support members can include anchoring structure for securing the support members to a support surface. In one embodiment, the concertina coils include two small diameter base coils and a top coil positioned on the base coils.

Abstract: A housing for interfacing a fiber optic cable with a semiconductor device allows simple insertion and removal of the cable by application of an axial force. The housing exerts a spring-like gripping force upon the cable and axially aligns the cable to the semiconductor device in order to minimize loss of transmitted light. A portion of the gripping force is translated into an axial force by a slanted ridge within the housing which acts upon a ridge on the cable to cause the cable to be forcefully abutted to the semiconductor device.
