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...

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.

Insect Processing Technologies for Chicken Feed

The growing scarcity of resources to produce increasingly demanded ingredients, such as soybean meal and animal protein meals, has doubled feed costs in the recent years. Thus, alternative protein sources, including insects, are urgently needed. Insects must be introduced in the feed chain, and...

New Synthetic Nematicides

Nematodes are among the most damaging crop pests. Very few available chemical nematicides can affect control, and some options are restricted by the Environmental Protection Agency and similar bodies. Nematodes damage plant roots, and reduce the plant’s ability to take up water and nutrients. The need is great to...

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...

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...

Preventing Adhesion of Cellulose to Steel

A client’s application joins cellulose and a resin binder. A combination of the binding agent and fibers sticks to the surface of the steel. The organization therefore seeks novel foams, coatings, and gels to act as a physical buffer between the fibers and the steel. The physical buffer must function...

Personal Cleansing Innovations

Personal cleansing after using the bathroom is a worldwide necessity, and various cultures solve that need differently. New devices must facilitate this type of cleaning and deliver soothing formulations onto the skin. The technology will serve as an alternative to Western dry toilet paper, European bidets, and...

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...

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...

Bacteria Elimination from Hard Surfaces

Long-term care facilities are subject to outbreaks of Clostridium difficile (C. diff) bacteria that form a hard shell, enter a vegetative spore state, and are thus able to withstand conventional cleaning. An active ingredient or mechanical/ electronic means must minimize the threat of C. diff and its...

Insulating Coating for a Ceramic Substrate

A client seeks an insulating coating for a ceramic substrate and a method of applying it. Electrical leakage from one side of the substrate to the other causes damage. A thin coating is preferred for the application, but the critical specification is the relative permittivity of the coating, which...

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.

CV Number Enables Tunable Ball Valves

A ball valve for process systems has a field-adjustable CV number. The CV number allows the valve to be “tuned” for its system. The ball, controlled by an actuator, is moved 0–90 degrees. An adjustable V-port then adjusts the CV number.

Industrial-Scale Gas Separation

A company has a process stream made up of a variety of gases and molecules. They seek effective industrial-scale technologies that separate methane from other hydrocarbons in the stream, as well as from lighter and heavier molecules. The large-scale gas streams must be separated into their constituent molecules at...
