Machine Vision Software

EyeSpector Version 1.5 software from Vision Components GmbH (Ettlingen, Germany) is suitable for a variety of gauging, inspection, orientation, color inspection, and recognition tasks. The Eye-Spector works with VC4xxx Series real-time and network ready Smart Camera series. The software now offers support for Robot Vision, making 2d/3d calibration and communication with robots easy. The software provides for brightness compensation, pattern matching, color measurements, and position compensation.

Laser Diode Modules

Photonic Products (Hertfordshire, UK) introduces the PM-NEOLD 635nm photon laser diode modules with an integral “Near End of Life Detection” feature that alerts users when a laser diode approaches the end of its operational life. The laser modules have optical output powers from 0.9 mW to 18 mW at a lasing wavelength of 635 nm, beam size of 3.5×1.5mm, operating voltage of 3-6 VDC, and operating temperature from -10°C to +50°C.

Piezoelectric Bolt Breakers and Bolt Fatigue Testers

Safer alternative to spacecraft explosive bolts may accelerate fatigue testing on Earth. A proposed family of devices for inducing fatigue in bolts in order to break the bolts would incorporate piezoelectric actuators into resonant fixtures as in ultrasonic/ sonic drills/corers and similar devices described in numerous prior NASA Tech Briefs articles. These devices were originally intended primarily for use as safer, more-reliable, more-versatile alternatives to explosive bolts heretofore used to fasten spacecraft structures that must subsequently be separated from each other quickly on command during flight. On Earth, these devices could be used for accelerated fatigue testing of bolts.

Optical Measurement of Mass Flow of a Two-Phase Fluid

Density and mass flow are estimated from wavelength-dependent scattering of light. An optoelectronic system utilizes wavelength-dependent scattering of light for measuring the density and mass flow of a two-phase fluid in a pipe. The apparatus was invented for original use in measuring the mass flow of a twophase cryogenic fluid (e.g., liquid hydrogen containing bubbles of hydrogen gas), but underlying principles of operation can readily be adapted to non-cryogenic two-phase fluids.

New Analgesic Actives

A company is looking for the next generation in analgesics. There are several fine analgesics on the market, both by prescription and over the counter, that vary in dosage load, dosage form, molecular size, speed of effectiveness, and side effects or toxicity (if any). New actives in the realm of analgesia are sought, and the form of their delivery is open. Certain aspects of the new analgesic are of particular interest, including speed of effectiveness, toleration, and (shelf-life) fragility.

In-Process Detection of Defects During Welding

Technology is required to enable “in-process” or real-time detection of defects during the welding process. This could be achieved by a system that can monitor any combination of accessible parameters during the weld process and then by analyzing changes, ascertain the presence of a weld defect, its locations, and, if possible, its nature. Potential solutions should be suitable for industrial production lines. Respond to this TechNeed at: Email: nasatech@yet2.com Phone: 781-972-0600

Up to Ten-Fold Production Increase for Deep, Heavy-Oil Fields

In oil field tests over 18 months, Direct Current Electrical Stimulation has shown up to a 10X increase in oil production for deep, heavy oil. The predominant method for recovering heavy oil is steam, but steam is limited to depths of 2,500 feet. There are no inherent depth limitations to Direct Current Electrical Stimulation. This patented technology — electrically enhanced oil recovery — uses direct current electricity to both heat and electrochemically upgrade the oil in situ, allowing for economical recovery.
