Abstract: Methods, apparatuses, and computer-readable media for distributing digital content. One embodiment comprises an apparatus comprising: a device (100) communications bus; coupled to the device communications bus (150), a bi-directional communications controller (110) capable of communicatively interfacing with a computer (710); coupled to the device communications bus (150), an integrated processor (130) capable of executing (270) computer-executable instructions; and coupled to the integrated processor (130), a storage module (140) capable of storing computer-executable instructions.
Abstract: A system for interchangeably mounting sighting devices on a plurality of firearms which includes one or more ring assemblies and one or more mounting assemblies. A sighting device is coupled to a mounting assembly using a ring assembly forming a mounting system. The system can then be mounted to one or more firearms using a single connector via two receptacles in the surface of the firearm. An entirely different sighting device and associated mounting system can be exchanged with the existing sighting device by removing the existing mounting system and replacing it with the new sighting device and mounting system. Each sighting device and mounting system are configured to have identical mounting assemblies that interface into standard receptacles in the firearm. In a similar manner a single sighting device and associated mounting system can be mounted on several firearms that each possess the two mounting receptacles.
Abstract: A frictionless transport apparatus for transporting an object from a first to a second station is disclosed. The apparatus has a frame extending between the first and second stations and a carriage mounted for movement along said frame, in a levitated condition. A substantial portion of the weight of the carriage and load is supported by biasing magnets on the frame and carriage. The carriage and load are stabilized in a levitated condition by magnetic interactions between a diamagnetic plate on the carriage and a magnetic array extending along the frame. The carriage is moved in its levitated condition by a frictionless drive system, such as an electromagnetic, electrostatic, or pneumatic drive system. Also disclosed is a method of frictionless transport of an object between first and second stations.
