Abstract: An energy harvesting method and apparatus for harvesting electrical energy from an elongate conductor through which alternating electrical current is flowing. The apparatus includes a magnetically permeable ferromagnetic metal U-shaped core. An electromagnetic coil surrounds the central section of the core. The core legs form an opening leading to a gap between the legs. The opening and gap are larger than the cross section of the conductor. The conductor is received through the opening into the gap whereat the flowing alternating electric current electromagnetically couples with the core and induces electric current in the coil. The opening is maintained open for selectively removing the conductor therethrough. The apparatus is encapsulated within an electrically insulative housing for electrically insulating and preventing physical contact with the conductor. The apparatus powers an electronic circuit which senses and transmits, via electromagnetic radiation, the operational status of the conductor.

Abstract: A buoy that is adapted to resist entanglement with a trawler net that may be dragged over the anchor and buoy. The buoy may have an indentation on the body of the buoy that causes the buoy to pivot as a trawler net pulls the tether down and slides across the buoy. A lead-in ramp surface increases in thickness from the lower end to a transition area spaced from the lower end. A reorienting ramp surface extends from the transition area to the side of the housing that tips the buoy to a generally horizontal orientation as the object traverses the reorienting ramp surface.

Abstract: An anchoring base and a buoy that are adapted to resist entanglement with a trawler net that may be dragged over the anchor and buoy. The buoy may have a plurality of cones that are secured to the tether in a spaced relationship proximate the lower end of the buoy. The anchoring base has a top side having an upper surface that defines a plurality of indentations between raised portions. The tether may be received in at least one of the indentations when the tether is pressed against the upper surface of the insert to protect the tether from being damaged or severed.

Abstract: A microwave oven cavity air flow system having a grease shield adapted for receiving a nominal flow of air and efficiently using that flow to rotate the antenna and to remove moisture from the cavity. The air is first concentrated into a directive stream which impinges the vanes of the antenna rotating structure. Then, the air is directed into a dispersed flow towards the front of the grease shield wherein a first portion is directed down along the door and a second portion is directed back along the underside of the grease shield to directly transfer water vapor rising from the food to a rear exhaust. The grease shield has a channel for receiving an antenna mounting cradle.

Abstract: A microwave oven having a low friction bearing support for a rotatable microwave feed assembly which includes a primary radiating antenna axially coupled to a cylindrical metal stub that vertically extends from the microwave cavity through an aperture into the waveguide where it is excited by microwave energy. The stub has a bottom cylindrical bore which inserts over a microwave transparent post that extends upwardly through the aperture from a horizontal cross bar suspended by two legs connected to the cavity ceiling. The cross bar may be oblique to the waveguide to centrally and positively align the post in the aperture. The roof of the bore has a downward spherical surface which provides a low friction bearing with the microwave post. The feed assembly also includes a microwave transparent turbine against which a stream of air is directed to rotate the feed assembly.
