  • Patent number: 10663666
    Abstract: This invention is a method and system for addressing structural weaknesses and geometric differentials introduced to a cable when splicing optic fibers. The apparatus and method utilize structurally integrated layers of protective polymers and bonding materials selected for strength and flexibility relative to their thickness. This results in an apparatus having a minimally increased circumference compared to the cable. The method and apparatus include one or more strengthening layers which allow the repaired cable substantially similar flexibility compared to the cable, but prevent formation of sharp bends or kinks. The strengthening layers also allow the repaired cable a resistance to tension similar to the original cable. The method and apparatus further include an outer layer having a geometric configuration which includes sloped terminating ends designed to prevent the reinforced area of the cable from being damaged by the force of objects or substances in contact with cable.

  • Patent number: 10216967
    Abstract: A USB-style data-transfer device employs volatile memory that is connected to an onboard power-storage device for data storage. Through this design, any data stored on the memory can be physically cleared by interrupting the supply of electrical power from the onboard power-storage device to the memory. Enhanced security relative to conventional USB flash devices is provided by the volatile memory-based USB-style data-transfer device as the memory can be physically cleared without being plugged into a computer system either automatically when the onboard power storage device runs out of electrical power to supply to the volatile memory, or by user initiation through either a programmed instruction to interrupt the supply of electric power after a set time period or the operation of a manual switch which interrupts the supply of electric power.

  • Patent number: 8866319
    Abstract: A pair of reverse-scissoring arms are configured to be rotatable and reverse-scissorable about a common central axis point. A volume expandable and volume contractible truck is operably disposed at each of the distal ends of the reverse-scissoring arms. Actuation of the arms simultaneously expands one of the trucks, increasing its volume, while contracting the other of the trucks, decreasing its volume. Operably coupled to each of the reverse-scissoring arms is an energy-supplied electric motor-generator. Energization of the motors actuates the arms, whereas actuation of the arms without energization of the motors generates electrical power in the motors. When submersed in liquid, the simultaneous expansion and contraction of the volume in the trucks generates positive and negative buoyancy, respectively, enhancing the dynamics of the truck expansion/contraction motion and the reverse scissorable arm actuation.

  • Patent number: 8771634
    Abstract: The present subject matter provides heat management while generating hydrogen gas from a hydride achieved by coupling a hydride with a hydrate. The present subject matter unexpectedly provides improved methods so that the heat released by the hydride during hydrolysis is accurately balanced by the heat absorbed by the hydrate as the hydrate undergoes a phase transition to a less hydrated or to an anhydrous form. Examples of heat-moderated hydrogen generating systems are provided, and include, among others: NaBH4/Na2SO4.10H2O, NaBH4/CoSO4.7H2O, and NaBH4/FeSO4.7H2O. The subject matter provides a methodology for determining the correct proportions of hydride/hydrate to use in preparing a hydrogen generator capable of operating at a nearly constant temperature at or near a phase transition temperature of the hydrate or at a higher temperature that is still within a desired temperature range, such as, for example, 30-90° C.
