Macrospray® nozzles produce consistent mists at very low pressure. The nozzles have a uniformly distributed droplet size (10–30 μm Sauter Mean Diameter), which provides greater contact between deodorant, for example, and odorcausing particles or dust. Droplet size can be tuned for the degree of dust...

A patented, one-piece, fiber-reinforced plastic composite chassis, produced by sheet molding compression, uses a highglass-content vinyl ester composite structural material, toughened with urethane for fatigue and damage tolerance.

An organization needs an inexpensive device to deliver a pre-measured amount of liquid evenly to a surface. The applicator is intended for a single use, must be able to be sterilized after final assembly, and needs to hold enough liquid or gel to cover about 1 to 3 square feet of surface...

A torque-feedback mechanism must measure force, pressure, and displacement. The hybrid system or multi-part assembly requires haptic, visual, sound, temperature, or vibration feedback instruments. The technology may take the form of either a standalone sensor cube that flashes according to pressure, or a material that...

Marcia Domack and John Wagner, engineers in the Advanced Materials and Processing Branch at NASA Langley Research Center, have worked with Boston-based metal fabricator Spincraft, focusing on a one-piece manufacturing process called spin forming. The team used...

Current transcranial color Doppler (TCD) transducer probes are bulky and difficult to move in tiny increments to search and optimize TCD signals. This invention provides miniature motions of a TCD transducer probe to optimize TCD signals.

The concept of combining a laser welding system with a conventional arc welding system (GTAW) was first proposed in order to improve the stability of the laser welding system and to allow greater flexibility in part fit-up. Prior research stated that using a YAG...

A team of Harvard scientists has developed a slick way to prevent the troublesome bacterial communities from ever forming on a surface.The researchers used their recently developed technology, dubbed SLIPS (slippery-liquid-infused porous surfaces), to effectively create a hybrid surface that is smooth and slippery...

A revision of the Waste Electrical and Electronic Equipment (WEEE2) Directive was published in the Official Journal of the European Union on July 24. While it is mainly for European waste and recycling industries, some aspects will have consequences for the medical device industry since,...

Researchers at Aalto University in Finland have developed the world’s first device designed to map the human brain combining whole-head magnetoencephalography (MEG) and magnetic resonance imaging (MRI) technology. MEG measures the electrical function and MRI visualizes the structure of the...
