James Webb Telescope Components Pass Tests

Development models for components of the Mid-Infrared Instrument on NASA’s James Webb Space Telescope (JWST) passed a series of temperature and vibration tests that show they can survive the ride to space. Now, engineers have begun building parts of the actual instrument.

Effects of Temperature on Polymer/Carbon Chemical Sensors

Experiments were conducted on the effects of temperature, polymer molecular weight, and carbon loading on the electrical resistances of polymer/carbon-black composite films. The experiment were performed in a continuing effort to develop such films as part of the JPL Electronic Nose (ENose), that would be used to detect, identify, and quantify parts-per-million (ppm) concentration levels of airborne chemicals in the space shuttle/space station environments. The polymers used in this study were three formulations of poly(ethylene oxide) [PEO] that had molecular weights of 20 kilodaltons, 600 kilodaltons, and 1 megadalton, respectively.

ML7 BGS sensors

Pepperl+Fuchs, Twinsburg, OH, has introduced the ML7 Background Suppression (BGS) photoelectric sensors that feature a 31 x 11 x 23 mm housing, and a sensing range of up to 350 mm. Background suppression optimizes the detection of variously colored targets without the need for reflectors or thru-beam sensing arrangements. Objects in the background, even directly behind the target, are ignored. The sensors feature automatic cross-talk protection that enables multiple sensors to be mounted side-by-side with no interference. LED indicators provide power and output status, as well as diagnostic information. The sensors also feature 4-in-1™ output technology that automatically detects the connected load, and sinks or sources as needed. The ML7 BGS sensors have an adjustable sensing range that can be customized. Applications include converting, material handling, packaging, and assembly operations that require long sensing ranges.

Tele-Supervised Adaptive Ocean Sensor Fleet

A software architecture and system deploys robotic boats to study ocean surface and subsurface phenomena such as coastal pollutants, oil spills, and hurricanes. The Tele-supervised Adaptive Ocean Sensor Fleet (TAOSF) is a multi-robot science exploration architecture and system that uses a group of robotic boats (the Ocean-Atmosphere Sensor Integration System, or OASIS) to enable in-situ study of ocean surface and subsurface characteristics and the dynamics of such ocean phenomena as coastal pollutants, oil spills, hurricanes, or harmful algal blooms (HABs). The OASIS boats are extended-deployment, autonomous ocean surface vehicles. The TAOSF architecture provides an integrated approach to multi-vehicle coordination and sliding human-vehicle autonomy.

Single-Layer Electrochromic Polymer Technology for Automotive and Architectural Glazing Light Control

DuPont’s electrochromatic (EC) technology for controllable light transmission in automotive and architectural safety glazing applications is based on an organic polymer film that can function as a controllable EC interlayer. This technology addresses the need for reducing the complexity of current EC technologies and can be used in rigid and flexible forms, large sizes, and curved shapes. It has applications in dynamic electrochromic glazing systems that undergo a reversible change in color from light to dark by application of a very low voltage. Target markets in automotive include sunroofs, mirrors, instrument clusters, windshield shadebands, sidelights, and backlights. The technology works either in transmissive or reflective mode. Transmissive EC devices are made with indium tin oxide electrodes that are fully transparent in the visible spectral range. All of the components of the electronic control systems are commercially available. Get the complete report on this technology at: Email: nasatech@yet2.com Phone: 781-972-0600

Tool-Free Engineered Composite Thermoforming Technology

Tooless Engineered Composite (TEC) is a patent-pending process that incorporates the benefits of a thermoformed plastic composite product and the strength of fiberglass reinforcement. This tool-free process utilizes the thermoformed shell as the tool surface in a closed mold process. The result is an extremely durable product with superior finish quality. The product has low to no emissions and uses soy and corn resin. The TEC process utilizes a multi-layer thermoformed shell producing products with a class “A” finish. Utilizing a multi-layer thermoformed shell eliminates painting, which reduces cost and produces low or no emissions. This multi-layer shell has a layer of acrylic that may be sanded and buffed if needed. The thermoformed shell allows for the use of various materials, finishes, colors, textures, and decorative patterns that may be utilized in different applications.
