Abstract:
A sub for a pipe assembly and system and method for use of the same are disclosed. In one embodiment, the sub includes a mandrel having a body section including an internal flow passage that extends generally axially through the mandrel from an upper connection end to a lower connection end. A battery charger is located within a recessed region within the mandrel. Capacitors include opposing spaced plates having contact segments thereon. An output power increasing, electrically resistive fluid is held within and partially fills an enclosed chamber. In response to movement of the sub, induced relative motion between the output power increasing, electrically resistive fluid and contact segments varies the fluid-contact segment contact within the enclosed chamber, thereby generating an electrical charge. An electronic circuit, which is coupled to the opposing spaced plates, is configured to transfer the electrical charge to a battery associated with the mandrel.

Claim (Index 20):
A sub for a pipe assembly, the sub comprising:\n a mandrel having a body section including an internal flow passage that extends generally axially through the mandrel from an upper connection end to a lower connection end; a recessed region within the mandrel; a battery charger including an enclosed chamber, the battery charger being disposed in the recessed region; a pair of capacitors located within the battery charger, each of the pair of capacitors including opposing spaced plates having contact segments thereon, the opposing spaced plates including electret; an output power increasing, electrically resistive fluid held within the enclosed chamber, the output power increasing, electrically resistive fluid partially filling the enclosed chamber such that a fluid motion varies a fluid-contact segment contact within the enclosed chamber; in response to a movement of the sub, an induced relative motion between the output power increasing, electrically resistive fluid and contact segments varies the fluid-contact segment contact within the enclosed chamber, thereby inversely alternating the capacitance between the pair of capacitors and triboelectrically generating an electrical charge; an electronic circuit coupled to the opposing spaced plates of the pair of capacitors, the electronic circuit configured to transfer the electrical charge to a battery associated with the mandrel.
