Abstract: A headphone stand, for supporting a variety of electronic devices and accessories, having a base portion and a tower portion. The tower portion is mounted on the top surface of the base portion and has a pair of parallel and substantially identical end plates, and a connecting part extending between the end plates. Each of the end plates has a plurality of fingers extending forwardly and rearwardly therefrom for supporting electronic devices and accessories. A plurality of upstanding walls extend upwardly from the base portion, defining slots for holding electronic devices. A USB hub provides a plurality of USB charging ports, such that charging cables can be used to charge various devices supported by the headphone stand.

Abstract: A system for measuring the concentration of an assay substance comprising a sensor having an optical fiber (10) on one end of which is coated a body (22). A fluorophor is dispersed within the body (22), the fluorescent activity of which is altered in relationship to the concentration of the assay substance. Light from a source such as an LED (40) is carried by the fiber (10) to the body (22). Light emitted by the fluorophor is carried to a detector unit (54) along the fiber (10). Concentration of the assay substance is determined by measurement of the characteristics of the growth in emitted light following activation of the LED (40).

Abstract: Multiple conductor cables are connected to horizontally distributed component equipments within a vertical array inside a cabinet. The cables are brought into the cabinet through or near the bottom and a clear space is provided within the cabinet generally parallel to the arrays. Each array has a plurality of cables, each consisting of a plurality of conductors. Starting with the lowermost, the cables to connect to a given equipment are collected into a bundle by retainer means, preferably a resilient U-shaped clip which can be sprung to fit into a hole in a plate along a cabinet wall. The cables are terminated in connector means which are plugged into horizontally distributed mating connectors for each component equipment supported on a stress relief panel supported by the cabinet. The clip for each bundle of cables is generally at the level of the component equipment to which it attaches so that it carries most of the weight of the cables.
