Abstract: The battery analyzer/conditioner system includes a battery analyzer/conditioner having an input port and an output port. The battery analyzer/conditioner operates to analyze, condition and test a group of rechargeable batteries. A cable is coupled between the input port and a remote control unit to transmit signals between the battery analyzer/conditioner and the remote control unit to enable the remote control unit to control the operation of the battery analyzer/conditioner. Another battery analyzer/conditioner also having an input port and an output port communicates with the battery analyzer/conditioner via a cable coupled between the output port of the battery analyzer/conditioner and the input port of the second battery analyzer/conditioner, wherein the first and second battery analyzer/conditioners are connected in a daisy chain network to permit the remote control unit to communicate selectively with any one of the battery analyzer/conditioner units.

Abstract: A universally adaptable battery charger connector which couples electrically a battery charger outlet to pairs of terminals of different types and kinds of rechargeable battery devices. The universal adaptable battery charger includes an attachment arrangement for engaging releasably one of the pairs of battery device terminals. The attachment arrangement includes a pair of electrodes coupled electrically to a battery charger outlet for helping to supply electrical current to the battery device terminals. The universal connector also includes a securing device for mounting removably on the battery device to be charged. Each one of the electrodes includes a resilient contact for pressing resiliently into engagement with the terminals to maintain an electrical and mechanical contact between the securing device and the battery device terminals.

Abstract: A communication system includes a filter device for passing only a desired carrier frequency, and a circuit for splitting the passed carrier frequency into a pair of signals. A circuit for feeding back one of the signals to the filter device for causing an oscillation to occur at the desired carrier frequency for direct broadcast purposes.
