Abstract: Elevator systems, methods, and devices comprising dual source light systems are described herein. Such elevator systems may be associated with or located within wind turbines and wind turbine towers. In embodiments, an elevator cabin may comprise a dual source light system further comprising at least one light source, a supercapacitor unit, an electronic circuit electrically connected to the at least one light source and the supercapacitor, and a housing unit. The dual source light system can receive energy from an external power source, convert one or more characteristics of the energy, e.g., voltage or current, and distribute the energy to the at least one light source. Any excess energy can be used to charge the supercapacitor such that when energy from the external power source is insufficient to power the at least one light source, such as during an outage, the electronic circuit draws energy from the charged supercapacitor.

Abstract: A mailbox whose construction is chiefly made up of a used rubber motor vehicle tire provides self protection from impact damage by utilizing the rubber tire's shock absorption qualities and also provides an environmentally responsible use for post consumer vehicle tires; thereby possibly reducing the number of tires sent to landfills.

Abstract: A spring box assembly for use in clamping mechanisms of the over-center type comprises two nested metal housings, at least one spring located between such housings, and means for resiliently holding said housings together with a predetermined initial tension applied to the spring. In a preferred embodiment, at least one metal pin is secured at one end to the bottom of the inside housing and slip fitted in holes in the outside housing at its other end, a helical spring is located around such pin and means are mounted on the other end of such pin for holding the two nested housings together with a predetermined initial tension applied to such spring.
