  • Patent number: 8523386
    Abstract: An illuminable safety rope includes an illuminable wire of a predetermined length surrounded by a light-transmitting insulative covering to thereby form an illuminable cable. The insulative covering includes a flange extending radially outward along its length. The flange is defined by opposing side portions and terminates at an edge portion. A fabric material is disposed over and secured to the opposing side and edge portions along at least the length of the illuminable cable to thereby form the safety rope. At least a portion of the illuminable cable opposite the flange transmits light to illuminate the safety rope along its length when the illuminable wire receives power. Additional floatation materials and/or wiring can be provided adjacent the flange and beneath the fabric to enable floatation and/or reinforcement of the rope, or a distress signal to be sent to an alarm.

High aspect ratio clay nanoparticles are positioned in the substrate in overlapping layers with layers of the substrate interposed. The invention also provides a method for forming an acoustically transparent low permeability encapsulant about an acoustic device. The method includes treating high aspect ration clay nanoparticles to make them organophilic. The treated nanoparticles are then mixed in a polymer resin in such a way as to form an intercalated mixture. A curing agent is added to the mixture, and the mixture is allowed to set. When set the resulting intercalated mixture produces an acoustically clear, low permeability polymer coating.

  • Publication number: 20130088887
    Abstract: An optical fiber switch (16) for alternatively redirecting an input beam (14) comprises a redirector (18) and a redirector mover (20). The redirector (18) is positioned in the path of the input beam (14) along a directed axis (344A). The redirector (18) redirects the input beam (14) so that a redirected beam (46) alternatively launches from the redirector (18) (i) along a first redirected axis (354) that is spaced apart from the directed axis (344A) when the redirector (18) is positioned at a first position (348), and (ii) along a second redirected axis (356) that is spaced apart from the directed axis (344A) when the redirector (18) is positioned at a second position (350) that is different from the first position (348). The redirector mover (20) moves the redirector (18) about a movement axis (366) between the first position (348) and the second position (350). The redirector mover (20) includes a stator component (320A) and a rotor component (320B) that moves relative to the stator component (320A).
