摘要： The present invention concerns a network node comprising: first and second modems and a digital switch having one or more ports for attaching peripheral devices, the switch being interposed between the first and second modems, first and second cables being' respectively connectable to the first and second modems, wherein the network node is operable as a point-to-point link Further, the invention concerns a network of such nodes, connected by cables to form a series of point -to "point links. The invention allows a new, cable-based network topology of point-to-point links, which finds particular application in environments such as underground mines, subways and tunnels.

摘要： A wireless communications unit is provided, such as a portable unit to serve as an access point and/or a repeater node in a wireless meshing network, including at least two removable power source modules engageable with and electrically connectable to the unit to provide electrical power thereto, and a mechanism to allow selective disconnection and removal of one power source module from the unit while maintaining connection and retention to the unit of another power source module. The mechanism comprises a rotatable wheel having a radially projecting portion (such as a cam lobe). When the wheel is rotated the projecting portion bears against a part of the first power source module to push it into an ejected position while electrically disconnecting it from the unit, to allow removal and recharge/replacement.

摘要： The invention generally relates to a field regulator, particularly a field regulator for a resonant circuit, a transmitter including such a field regulator, a proximity detection system including such a transmitter, and a method of regulating a resonant circuit. In one aspect the invention provides a field regulator for a resonant circuit, the resonant circuit including an inductor coil around a core, the field regulator including a DC bias circuit configured to apply a DC bias current to the inductor coil for regulating an electromagnetic field generated by the inductor. The DC bias circuit can be used to selectively change the inductance of the inductor in the resonant circuit so as to maintain a consistent field strength in a changing environment, particularly to take into account the presence of large metal bodies which might otherwise adversely impact on operation. In particular, the DC bias current may be used to selectively change the natural frequency of the resonant circuit so as to shift the resonant circuit towards a desired resonance point.

摘要： The invention relates to an inductor, and particularly to an inductor for a transmitter circuit. The invention also concerns a transmitter including said inductor, a proximity detection system employing such a transmitter, and a method of making said inductor. The inductor of the invention includes a core having non-uniform permeability and a conductor winding arranged around the core. When used in a transmitter circuit, this allows an induced electromagnetic field to propagate through the core in a more efficient manner than otherwise possible, so resulting in a higher dynamic field strength for a given resonant circuit drive.
