According to an embodiment, an electrically switchable mirror includes: a first electrically switchable layer of cholesteric liquid crystal material, the first electrically switchable layer having a first state in which right-handed circularly polarized light incident thereon is reflected and left-handed circularly polarized light incident thereon is transmitted and a second state wherein right-handed and left-handed circularly polarized light incident thereon are transmitted; a second electrically switchable layer of cholesteric liquid crystal material, the second electrically switchable layer having a first state in which left-handed circularly polarized light incident thereon is reflected and right-handed circularly polarized light incident thereon is transmitted and a second state wherein right-handed and left-handed circularly polarized light incident thereon are transmitted; and a first electrically switchable wave plate disposed between the first and second electrically switchable layers.

A method of operating a production line comprises the steps of supporting equipment in the production line on a plurality of crawlers comprising at least one rolling track and a structural support for supporting the equipment. A first plurality of lifting magnets coupled to an interior surface of said at least one rolling track is configured to oppose a second plurality of lifting magnets coupled to an exterior surface of said structure support to lift the structural support, such that the structural support floats between and within said at least one rolling track. The magnetic fields experienced by the first and second plurality of lift magnets are adjusted to translate the at least one rolling track, such that the crawlers move along the production line.

Method of operating a production line

An electromagnet and associated apparatus and method are provided. The electromagnet includes a core and at least one winding disposed circumferentially about the core such that the winding extends at least one revolution around the core. The electromagnet further includes at least one spacer having channels defined therein and disposed circumferentially about the core and adjacent to the at least one winding. The channels facilitate cooling by directing fluid about the windings of the coil as fluid is introduced into the electromagnet.

Electromagnet having spacer for facilitating cooling and associated cooling method

An equipment-carrying crawler () includes a rolling track () and a structural support (). The structural support () supports equipment (). Lifting magnets () are coupled to the rolling track () and to the structural support (). The lifting magnets () are configured to oppose each other, lift the structural support (), and aid in the translation of the rolling track ().

Superconducting crawler system for a production line

A rivet gun system includes a rivet gun frame having two ends. A die is coupled to one end, and a force sensor coupled to the rivet gun frame. The force sensor detects force applied to the die and generates a force signal in response to the force. A holding coil defines a channel within the rivet gun frame and generates an electromagnetic force along the channel. The channel includes an end defined by an end stop and an end defined by the die. A main coil further defines the channel between the holding coil and the die. The main coil also generates an electromagnetic force along the channel. A plunger slides through the channel in response to the electromagnetic forces. A force sensor electronics controller receives the force signal from the force sensor and activates the holding coil and the main coil in response to the force signal above an activation threshold.
