Abstract: An electrical arc detector for a series electrical connection as may be associated with an electric meter may comprise: an arc detector housing; a source of electrical power; a de-tuned resonant tank circuit configured to receive a magnetic field and/or an electric field generated by an electrical arc at a series electrical connection; an electrical detector for detecting signals generated in the de-tuned resonant tank circuit responsive to the magnetic field and/or the electric field generated by an electrical arc; and an output device responsive to the electrical detector and configured to provide a human perceivable indication of detection of an electrical arc at the series electrical connection.

Abstract: An electric meter contact arc detector is mountable to an electric meter base and may comprise: a de-tuned resonant tank circuit configured to receive a magnetic field and/or an electric field from an electrical arc at a stab contact; an electrical detector detecting signals generated in the de-tuned resonant tank circuit responsive to the electrical arc at the stab contact; and an output device indicating detection of an electrical arc. A disconnect device responsive to the electrical detector and configured to interrupt an electrical connection to the stab contact, may be provided. An electrical arc at the stab contact may thus be detected and may cause an electrical connection to the stab contact to be interrupted.

Abstract: Interactive, low power, collapsible, intelligent, multi-media display systems for use as hand-held, portable communications devices are disclosed. A display communications device according to the invention can include a housing that contains a processor, radio transceiver means for transmitting and receiving radio signals, and a collapsible display that is mechanically coupled to the housing and electrically coupled to the processor. The display can have a surface area that is larger than any cross-sectional area of the housing. The processor can be adapted to extract display data from input radio signals, and to provide a representation of the display data to the display.
