In electrical connector assemblies 2, 102 comprising mating receptacle and plug connectors, a force is generated during mating which urges the receptacle and plug connectors away from an intermediate, partially mated position in which arcing might occur between terminals in the mating connectors. The transmitter comprises an input device for receiving a DTMF dialling signal from said telephone, and a transmitter circuit housed in the casing for subsequently processing the signal and then transmitting it as a remote control signal for receipt by the receiver. The linear encoder includes a holder in a position in a measuring direction, wherein the holder fastens the scale to a body to be measured by the linear encoder at a fixed point while bypassing the support. The battery sensor includes a first die including a first and second input terminal configured for coupling to the positive and negative potential terminals of the battery; and a second die including the voltage sensor, wherein the first and second die are electrically isolated from each other. This knowledge is employed to determine coefficients for combining the received composite signals received in the first and the second time interval in order to recover the desired signal in a manner that maximizes the SNR associated with the desired signal or completely cancels the dominant interference. Further, because the smart card assembly can be manufactured by automated equipment, manufacturing costs are reduced.
