New sensations for saline sprays and washes must moisturize dry nasal passages and relieve a stuffy nose. Additives such as eucalyptus or sesame oil, for example, produce coolness or warmth. The desired effects must calm, soften, and relieve symptoms. An antibacterial effect and a physical rinse are of...

A technology provides a full-surface, bonded, nonwoven fabric with a tensile strength suitable for packaging, bubble packs, and other applications requiring tear resistance. Fullwidth bonding, compared to the more common patterned point bonding, produces the high-strength fabric. The thin,...

A traditional sulfur-adsorption bed uses microwave energy to remove, or desorb, captured impurities. Conventional adsorption beds use heat and sometimes vacuum to cleanse the bed of sorbents; the process is energy-intensive and can reduce sorbent life. By using microwaves, the new technology...

To enhance transportability and shelf life, many drugs and pharmaceuticals are distributed as freeze-dried formulations. The formulations must be dissolved before they can be injected. A client therefore seeks a new device or container that helps lyophilized preparations dissolve rapidly and completely with diluents such as...

Because of their weight and the weight they bear, most grab-bars must be installed permanently in a home, usually by drilling through the wall material and into a wall stud. In the case of grab-bars installed in a tub enclosure or shower, a permanent hole may need to be drilled through ceramic tile, thus making a change...

The Inclinos 3DS inclination and acceleration sensor, based on thermodynamic effects, exhibits no hysteresis in response signal (output lag). A power distribution of four heaters is controlled by a closed loop, and the temperature of each heater is constantly affected by any acceleration. The...

A water/propylene glycol-based formulation acts as a heattransfer medium and reduces the corrosion of sensitive metals by 10x to 100x in heat exchangers, radiators, cold plates, and associated plumbing. The water-based cooling fluid can be used with equipment containing a variety of metals, while still...

A company produces and stacks sheet goods that have a naturally viscous and sticky surface material. The sticky material is applied at about 480 °F. During application, the coating has a specific gravity of 1.03 to 1.70, and a viscosity of >5000 cps. A release material needs to be applied to the substrat...

Without producing clumps, a professional adhesive must be poured in a consistent and smooth way. A company seeks a dispenser/ applicator that can handle a thick, gelatinous, preformed, professional-quality adhesive. Currently, a polymer dispersion of polyvinyl pyrrolidone is used. While the stearates thicken the...

Transverse Flux Machines (TFMs) are brushless motors and generators that use permanent magnets. A TFM’s direction of magnetic flux is perpendicular to the direction of force, instead of parallel to it, as in a standard electric motor or generator. The machines are also inherently...

A solar tracker enables the construction of independent power sources and a micro-grid. The mechanism of the land-intensive system has two independent virtual axes for azimuthal moving and altitude moving. After the solar panel is aligned, the tracker drives it to move from east to west...

A company must deliver a measured amount of antiseptic/ antimicrobial formulation to a specific surface area (between 1 to 3 square feet) and be able to verify visually that the area has been adequately covered and treated. Currently, the antimicrobial formulation is a liquid with a viscosity...

Beverages, when served cold, quickly heat up during consumption. A client seeks material and process technologies that will insulate against heat gain or actively reduce temperature of liquids contained in glass bottles or metal cans. Processes that enable the printing, coating, and...

MP3 and MP4 players, along with powerful Class-D headphone amplifiers, can cause hearing loss due to a continuously high sound pressure level (SPL). A Hungarian university has developed an electronic device for preventing hearing loss and simulating ear distortion. The invention is a simple module that models...
