Abstract: An optical fiber sensor, disposed in the insulation of a wire or cable, provides a means of detecting damage to the insulation of the wire or cable. An optical measurement device, such as an optical time domain reflectometer (OTDR), coupled to the sensor, detects the presence and location of a sensor fault or stress. The sensor is positioned between the conductor and the outside surface of the conductor so that the OTDR will sense damage before the conductor is exposed or contacted by a damage element.

Abstract: A reforestation and nourishing practice by the use of a lighter-than-air airship system, for dispersing and planting tree saplings, primarily in remote regions which may have been devastated by fire, where access to such regions by personnel and ground equipment is difficult. The airship system comprises an aerodynamically configured structure having a semi-rigid keel or skeleton, where lift is provided by helium, with the keel mounting a liquid management mechanism consisting of a reservoir open to the outside for resupply of liquid or water, a conduit leading to a holding tank, and a piping distribution and nozzle assembly below the airship system to spray or dispense the liquid or water over selected areas to water or nourish the newly planted trees. The mechanism for temporarily storing and eventually dispensing the tree saplings is a rack mounting at least one cylindrical canister containing plural compartments.

Abstract: An electrical safety device is disclosed which utilizes a sensor conductor configured in a continuous loop and disposed in an electrical component so as to sense overtemperature or mechanical damage over a length or wide area of the component. The sensor may be simple insulated or non insulated copper wire. A low voltage potential is maintained across the sensor conductor. The sensor circuitry includes ambient temperature compensation.
