The package of cool end devices of float glass line must protect the contained devices from damage during transportation and storage.

Water flow rate through terminal devices in an air condition water system with a single pump is controlled by the bypass valve when the air conditioning system is under part-load.

The water flow rate through the terminal devices in water system with single pumps is controlled by the by-pass valves when the air conditioning system is under part-load.

There is no TCP/IP and PPP in the GPRS module and many terminal equipments?熏 so these make the application in terminal equipments is too hard.

A load control center with distributed C/S structure is designed,and the practicable terminal equipment (FRTU)is also designed for storied buildings with more households,which can collect hundreds of power parameters.

Some methods suitable to reliability analysis for the terminal equipments of automatic fare collection (AFC) system operated actually of rail transit have not been found as yet.

In order to satisfy the operation demand in using IC card according to the one card through regulation of Beijing,the paper describes AFC system for Beijing subway Line 5,including the system design,system structure,network structure,application system and functions of SLE equipment.

The state of terminal device is critical to IC card system which consists of different kinds of terminal device.
