Low-Cost Technology Detects Bad Breath

Most individuals experience bad breath (malodor or halitosis) occasionally, but few people can selfdiagnose when it occurs. Proto - types and initial human trial clinical tests have been completed on a low-cost bad-breath detection device. The detector changes color when the user blows through a tube.

Time-Based Tracker Boosts Solar Energy Production

Solar panels are normally positioned at a fixed position. If a panel uses a tracking system to follow the movement of the Sun, however, more solar energy can be collected. Instead of having light sensors that are often disturbed in cloudy environments, a new time-signal-based system uses a programmable logic controller (PLC) to give a start signal at the end of a fixed time.

Zeolite Production Method Removes Soil Pollutants

X-type zeolites use an ion-exchange mechanism to capture and retain heavy metals for soil and water remediation. Zeolites are hydrated aluminosilicate minerals characterized by a three-dimensional open structure. Their cation exchange capacity (CEC), large surface area, and porosity allow the absorption and encapsulation of pollutants. The geopolymer product, containing the zeolites in formation, can be applied directly to contaminated soil, thus immobilizing toxic heavy metals within the zeolite structure during growth and formation.

Low-Loss Dielectric Materials Improve PC Boards

Low-loss dielectric materials are available. The hydrocarbon- based, fiber-reinforced composite sheets can be applied to printed circuit boards and IC chip packaging. The material has a very low dielectric constant and low dissipation factor up to GHz range frequencies, and is advantageous for emerging high-frequency electronics applications as a printed circuit dielectric sheet.

Floorboard Locking Technology Features A/A Splicing

A locking technology can be widely used in the hardwood and laminate floor installation process. After being spliced, the two-locking structure has bearing capacity similar to that of a whole single material. The technology can be reversely disassembled, and both sides of the locking device are tightly sealed. The glue-free structure has multiple applications, including use in laminated boards, composite floorboards, furniture, and a new separable spliced process, other than welding, for metal boards with thickness over 5 mm.

Reseatable Pressure Relief Valve Fixes Leaks

Reclosable pressure-relief devices that employ a frusto-conical valve assembly or spherical valve assembly have been found to leak under vacuum. A new technology fixes leaks in low-pressure (less than 50 psi) relief valves. The invention adds a ring inside the valve. Both the valve seat and the sealing surface of the valve head are annular planar confronting surfaces oriented substantially perpendicular to the valve axis, and the resilient valve seal is an annular O-ring. To form a vacuum- tight seal, the O-ring is compressed between two planar mating surfaces by the valve spring. Pressure relief capacity is maintained, while providing a vacuum-tight seal during normal operation.

Hydrogen Degassing System Features Ceramic Rotor

A system for degassing hydrogen uses silicon nitride ceramic rotors. The technology’s rotors stir molten aluminum and disperse the gas. By adding bubbles of an inert gas, hydrogen is drawn out from the metal, which otherwise would cause voids and substantially weaken castings.
