An embodiment of the present technology provides an apparatus, comprising at least one compass sensor and at least one main electronic board capable of determining a mismatch from said compass sensor and further sending a signal to a at least one vehicle control board to activate at least one security action. The present technology also provides for a security method, comprising determining at least one variation in a magnetic field with at least one magnetic sensor, amplifying said variation by at least one electronic amplifier, processing said variation by a least one electronic board and receiving said processed variation by a vehicle control board to trigger at least one security action in an alarm system. The technology also comprises an alarm circuit, further comprising an electronic compass sensor to sample an incoming magnetic field and output a signal an electronic board to receive said signal and comprise a plurality of NOR gates, transistors, resistors, capacitors, operational amplifiers, wherein said electronic board is capable of processing said signal and a vehicle control board to receive said processed signal to trigger at least one security action in an alarm system.
A storage receptacle for the collection of trash, litter, garbage, etc. , particularly in public places such as recreational grounds and picnic areas, is fabricated of formed concrete for strength and stability, and has a cantilevered closure lid, normally locked in closed, covering relation, but which may be unlocked and readily swung between open and closed positions by an attendant whenever necessary for emptying. Side openings just below the lid serve as access to the receptacle for disposal use by the public.
A hanger, in combination with a drafting table and more particularly with a cylindrical paper protector attached to said drafting table, for supporting drafting tools and more particularly an electric eraser is described. Said hanger is formed as a one piece integrally molded device comprising an arcuate portion shaped as a partial cylinder which is generally resilient so it can be installed by snapping it on said paper protector, or inserted onto either end of said paper protector and once installed it can be moved to any location along said paper protector. The hanger also includes a hook-like portion, or a sleeve like portion, or a combination of both, extending from the arcuate portion, providing a surface for receiving and supporting an electric eraser or some other drafting tool.
