Superconducting electronics often require high-density microwave interconnects capable of transporting signals between temperature stages with minimal loss, cross talk, and heat conduction. We report the design fabrication superconducting 53 wt% Nb-47 Ti (Nb47Ti) FLexible coAXial ribbon cables (FLAX). The ten traces each consist a 0.076 mm O.D. NbTi inner conductor insulated PFA (0.28 O.D.) she...

─ This paper deals with an impact of receiving antenna placed in a metal enclosure on an electromagnetic field distribution within the enclosure, and thus on its shielding effectiveness. In an experimental setup, a frequently used tool for measuring the electromagnetic field level at certain points within the enclosure is a dipole antenna connected to a measuring instrument via a coaxial cable....

A two stage Magneto-Cumulative Generator employing simple construction techniques and inexpensive explosives has been explored by the Air Force Weapons Laboratory. The first stage in the cascade MCG system is constructed with a helically wound, insulated cable stator and an aluminum armature filled with (Comp C-4) explosive. The 0.5 1 MJ output energy of this generator is coupled, inductively, ...

The recent advance in Field Programmable Gate Array (FPGA) technology hasbeen largely embraced by the communication industry, which views this technology asan effective and economical alternative to the design of Application Specific IntegratedCircuits (ASICs). The primary reasons for switching to FPGAs are lower developmentand non-recurring engineering costs, the flexibility to...

This paper introduces a new web based method to remotely upgrade firmwares of Cable Modems (CM) which are integral part in providing high-speed Internet access through Hybrid Fiber Coaxial (HFC) networks. Also, it discusses various practical problems arising in the upgrading process. Traditional upgrade has been performed by modifying the CM configuration file. This paper shows a new web based ...

Lasers and LEDS Electrical to optical video converters generally have a BNC coaxial cable connector at the input and a fiber optic connector on the output. In order to get the digital bits down the fiber optic cable, a light emitting device is used, onto which the digital signal is modulated. Either a laser or an LED (Light Emitting Diode) is used for this purpose. Lasers are more expensive, bu...

Recently, coaxial cable networks have received much attention in the context of interactive application [1,2]. In countries with a high penetration of CATV (e.g. Belgium >90%), the cable network forms a viable alternative to classical telephone networks. Envisaged applications are telephony, interactive television, home-shopping, video-ondemand, high-speed Web browsing, etc. The interactive nat...

This summary aims at presenting an overview of the CEC-ESPRIT AVS-RIO (Advanced Video Surveillance Advanced Video Surveillance – Cable Television Based Remote Video surveillance System for Protected sites Monitoring) project. The peculiarity of the project consists both in the video-surveillance application considered (i.e. the monitoring of tourist and naturalistic places), and in the communic...
