US Classification:

36167901, 361500, 361502, 29 2503, 977742, 977948

Abstract:

Electrical devices having a plurality of stacked electrode layers are described. At least one of the electrode layers contains continuous fibers that are infused with carbon nanotubes. The continuous fibers can be disposed upon an electrically conductive base plate. The electrical devices can further contain an electrolyte contacting each electrode layer and a layer of separator material disposed between each electrode layer, in which case the electrical devices can form a supercapacitor. Such supercapacitors can have a capacitance of at least about 1 Farad/gram of continuous fibers. The capacitance can be increased by coating at least a portion of the infused carbon nanotubes with a material such as, for example, a conducting polymer, a main group metal compound, and/or a transition metal compound. Methods for producing the electrical devices are also described.

International Classification:

F41F 3/04

US Classification:

89 1806, 89 8, 124 3

Abstract:

Restraint release devices, systems and methods may enable actuation of a release function without using chemically energetic or thermally sensitive devices, and may employ an electromagnetic (EM) force to mechanically separate components of a fastener. A pulsed power system having a capacitive discharge circuit may be used to supply an electric current pulse to generate the EM force. The EM force can be applied to a retaining wire that surrounds and holds intact a segmented fastener. The EM force may cause the retaining wire to increase in length, thereby relaxing its hold on the segmented fastener and allowing the segments to separate and release the restraint mechanism. Restraint mechanisms using such EM restraint release devices, systems and methods may not need periodic recertification or replacement of energetics and may not have a risk of cook-off resulting from heat soak of thermally sensitive devices during operational and fault scenarios.
