Remote Cloud-Height and Visibility Sensing

A small, low-power automatic sensor technology is needed to determine the cloud coverage, cloud ceiling height between 3,000 to 20,000 feet, and visibility up to at least five miles. These measurements must be provided in day and night conditions. The devices need to be small for easy placement at remote sites (not necessarily near cities or airports) and must operate autonomously.

Non-Damaging Cell Wall Defrosting Method and Apparatus

A defrosting technology was developed to protect cell walls and the quality of frozen products during defrosting. Potential applications include the medical and pharmaceutical industries, cosmetic materials, and foods. The system seldom breaks cell walls because of its quick temperature rising and its high-level uniform heating. In the frozen food field, this system can prevent dripping, and loss of quality and nutrition.

Cargo Drop Air Delivery System

The ADCA aerial delivery system reduces cargo loading time, is safe for fragile cargo, and allows loading and unloading to be performed by one person (no special training required). The drop container is designed with a tubular frame, padding materials, a shock-absorbing cushion, and side and bottom air bags to withstand impact as it drops to the ground so that the box remains intact and secure. All types of aerial drops (high/low velocity) are possible, and the system is compatible with existing ranges of parachutes. ADCA is very stable, and highly targeted aerial drops can be achieved due to a weighted-bottom feature. The ADCA system comes as a single unit with no parts to assemble and a single unit may be used repeatedly. Applications include humanitarian aid and relief efforts, and resupplying military troops in hostile territory.

Electric Motors vs. Fluid Power: Robotic System Designers Have a Choice

Robotic system designers should choose the right power source for the job. Often, electric motors are chosen without thinking about the benefits of hydraulics or pneumatics. For applications where precise control of large forces and smooth motion are required, or applications that require “forgiveness” in the motion, fluid power can deliver significant benefits compared to electromechanical motion.

Lead Screws Used in Diamond Analyzer

Traditionally, once they are shaped, but before they are mounted, diamonds are rated by the “4 Cs” — clarity, color, carat, and cut. Modern gemology, however, grades finished diamonds by a more accurate standard: light performance. The quality of how a diamond innately captures and “plays” with light separates a superior gemstone from a flawed one. Supporting 10 million people and recording a profit of $1,010 billion in 2006, but facing a global supply crunch and competition from gem-quality synthetic diamonds, the diamond industry must get superior stones on the market quickly and reliably. For quality assurance, many firms have turned to the BrillianceScope™ Analyzer from GemEx (Mequon, WI) to measure the light performance of finished diamonds in a comparative test against some of the industry’s highest-rated stones. GemEx utilized the RGS™ Rapid Guide Screws from Kerk Motion Products (Hollis, NH) to maintain the precision of the BrillianceScope’s testing mechanism.
