A strain relief system for the backside of a fiber optic connector has a controlled bend radius defined by the formula R=[(W+t) 2 /2(1-cos φ)] 1/2 , where W is the rib thickness, t is the width of spaces between the ribs, and φ is an angle defined by comers of the ribs which engage each other at the minimum bending radius and a pivot point about which the ribs pivot relative to each other.

An electronic faucet ( 10 ) mounted on a countertop ( 12 ) includes a housing, at least one fluid inlet line ( 24 a , 24 b ) extending into the housing, a fluid outlet ( 46 ) from the housing, a solenoid ( 142, 143 ) for operating a valve controlling the fluid flow between at least one inlet line and the outlet, and a control circuit ( 206 ) for controlling the opening and closing of the valve.

The present invention relates to a fiber optic cable assembly (100) comprising (a) a connector subassembly comprising a fiber optic (300) cable terminated in a connector, the fiber optic cable having a minimum bend radius; and (b) a strain relief boot attached to the connector subassembly, the strain relief boot comprising a core portion, a flexible extension having a proximal end and a distal end, the proximal end extending from the core portion, and a means (26) for retaining at least a portion of the fiber optic cable which is disposed along the flexible extension. The flexible extension does not have a predetermined bend.

A multi-link boot assembly has a number of separate links which can be connected to form a flexible boot assembly capable of maintaining a predetermined bend radius as off-axial loads are applied, thereby effectively dispersing stresses along a cable as the cable is flexed or bent. Each link of the multi-link boot assembly includes a body portion defining a lengthwise extending bore for receiving the cable. The body portion extends between first and second opposed ends and generally includes a female section at the first end and a male section at the second end. The female section defines an opening for receiving the male section of another link during the assembly of the multi-link boot assembly. In order to connect each link with another link to form the flexible boot assembly, each link includes a connecting element at each of the first and second opposed ends which cooperably engages a corresponding connecting element of an adjacent link. As a result of the mechanical interconnection of the links of the multi-link boot assembly, the multi-link boot assembly will permit the cable to readily bend or flex until the predetermined minimum bend radius of the cable is reached, at which point the boot assembly will prevent further bending of the cable even in instances in which increased off-axial loads are applied to the cable.

A sheathing for optical fibres and for optical fibre cables comprises a continuous length of tubing with the tubing walls being designed to allow the tube to be bent to a predetermined radius but to hinder its bending to a radius smaller than the predetermined radius. The tube walls (12) include portions (18) which are spaced apart when the tube is straight, but abut one another at (20) when the tube is bent to the predetermined radius.
