Devices for insulating the electrical terminals of cylindrical batteries, such as lithium-ion cells, to prevent the occurrence of shorting. One configuration is a device or apparatus which covers one or more terminals of the cell, thereby providing an insulative barrier, while still allowing the cell to be used. Another configuration is a cell covering partially covering the topmost portions of the negatively charged exterior cell case, closest to the positive terminal of the cell, and attaching the covering via a circumferential appendage which locks onto the cell. In another configuration the cell covering extends axially down the side of the cell case to cover part of, or the entirety of, the side of the negatively charged case.

A leak alarm system for a petroleum pipeline includes one or more detectors installed in the ground adjacent to a pipeline, each detector having a tubular enclosure with a diode light source and photosensor located at the opposed end of the tube. The tubular enclosure is fabricated of a microporous material that has microfiltration properties: it is hydrophobic, so that soil water will not enter the enclosure, but also oleophilic to enable petroleum and related substances migrate through the material of the tubular enclosure and accumulate therein. The petroleum-like materials scatter the beam and diminish the sensor signal, causing a leak alarm signal to be generated.

Method and apparatus for detecting and monitoring oil spills and leaks

An apparatus and method for identifying, measuring, and monitoring metal loss through corrosion or other deleterious factors in ferromagnetic piping and ferromagnetic objects. Drive coils secured to the object are driven to emit a magnetic field which is transmitted through the object by magnetic domains in the object. Response coils detect the magnetic domains and generate a response signal. The drive and response signals can penetrate insulating materials and non-ferromagnetic metallic coverings of the piping and vessels. The system operates reiteratively over an extended period of time, e.g., months or years, to detect loss of magnetic domains which is an important indicator of corrosion and deterioration of the object.

A method for creating a 3D map of the surface contours of an object includes projecting a variety of patterns onto the object, and imaging the patterns as they fall on the object to encode the topographic features of the object. In one embodiment a three dimensional image is taken in a single flash to avoid blurring due to motion of the object. Thereafter a secondary pattern is projected to detect changes in the initial image. The images are processed in a computer program in a manner such that a complete 3D map of the surface of the object is obtained in digital form. Reiteration of the method can detect motional variation such as a breathing human, flexure of a complex mechanical structure, or a stress-strain testing of an airplane, vehicle, beam, bridge, or other structure.

A metallic insulated container (e.g. vacuum) such as a cup, mug, tumbler, bottle, coffee maker and brewing container is combined with a solid state thermal electric generator to create a container which heats and cools food and beverages and keeps the food and beverages hot or cold.
