When the transponderis disconnected (not shown) from base stationthe system communicates via external antennaby radio link with a local base station within a cellular phone network. The base stationprovides means to recharge the batteries (not shown) of cordless phonevia connectorsand transponder unitvia connectorswith dc supply being provided by power plugvia cableThe transponder unit may include a display screen and PDA electronics (not shown), or, be incorporated within a portable computer (not shown).

Multi-purpose mobile cordless phone system

A sealed lead acid recombination electric storage cell comprises a container containing alternating positive and negative plates separated by separators. Each separator includes reinforcing means extending over substantially its entire area and constructed to define a plurality of apertures and being surrounded by microfine glass fibre material. The plates and separators are under a compressive force and the reinforcing members are so constructed and arranged that the major proportion of the compressive force is transmitted through the reinforcing members while the major proportion of the area of the plates is contacted by the glass fibre material.
