Micro-Molded Spacers Protect Thermal Insulation of Cryogenic Propellants

Micro-Molded IMLI Matrix part Phillips Plastics Corp. Prescott, WI 877-508-0252 http://phillipsplastics.com To achieve a high level of energy density as well as green environmental performance and safety, NASA prefers to use cryogenic propellants such as liquid oxygen, hydrogen, and methane to propel their spacecraft. However, these propellants are at very cold temperatures, as low as -423°F, and must be stored in thermally insulated tanks to keep the contents from boiling off. Next-generation NASA exploration missions will require spacecraft such as the Altair Lunar Lander to maintain cryogenic propellants for up to six months.

Lenses Monitor Hubble Space Telescope Servicing in Orbit

C-mount Xenoplan and Cinegon lenses Schneider Optics Van Nuys, CA 818-766-3715 www.schneideroptics.com Schneider Optics’ C-mount Xenoplan and Cinegon lenses were selected by NASA to monitor aspects of the recent Hubble Space Telescope servicing mission. During the rendezvous between the shuttle Atlantis and the Hubble Space Telescope, and thereafter — while seven astronauts replaced six gyroscopes, batteries, and a sensor used to guide the telescope — the lenses were the “eyes” of the cameras that delivered high-resolution images to the shuttle and to engineers on Earth.

Disk Lasers in the Photovoltaic Industry

Diverse types of lasers, such as nanosecond, pulsed, and excimer, have been considered for various applications in the photovoltaic industry, including edge isolation, edge deletion, drilling for back contact, cutting of Si-wafer, and patterning of crystalline solar cells. High power lasers, with high stability and high efficiency in addition to high beam quality, are needed now more than ever.

NASA Research Will Help Aircraft Avoid Ocean Storms and Turbulence

NASA is funding the development of a prototype system to provide aircraft with updates about severe storms and turbulence as they fly across remote ocean regions. Scientists at the National Center for Atmospheric Research (NCAR) in Boulder, CO — in partnership with the University of Wisconsin — are developing a system that combines satellite data and computer weather models with artificial intelligence techniques.

Large Area OLED Device

Novaled (Dresden, Germany) developed a 15 x 15 cm white OLED with a thickness of less than 2 mm. The Novaled OLED stack allows for a natural and warm white light, performing with a high color rendering index (CRI) of 90 - which looks similar to sunlight or what is delivered by incandescent bulbs.

Ultra-Portable Data Acquisition System

Dewetron USA, Wakefield, RI, has introduced the DEWE-43-V, an ultra-portable data acquisition system that includes eight 24-bit dynamic analog input channels with >100 dB dynamic range; eight synchronous counters for recording speed, counts, RPM, and duty cycle from tachometer and pulse train sources; 24 TTL level digital discrete inputs; and two high-speed CAN BUS ports. The system is made from a solid block of aluminum for rugged conditions, and is connected via USB to any Windows PC. Each of the eight analog inputs is a multifunctional signal conditioner capable of handling full-bridge strain gages and voltages up to ±10V. MSI adapters are available for IEPE accelerometers and microphones, high voltages, thermocouples, RTD sensors, and charge accelerometers. The adapters are automatically recognized by the DEWESoft-SE software, which adjusts the input ranges and engineering units to match them. GPS and video sensors can be connected to the PC and recorded in sync with the analog data from the DEWE-43-V. The unit is powered via a 6-36 VDA, and includes an AC/DC adapter with additional adapters for common AC plugs worldwide. For Free Info Visit http://info.hotims.com/22922-120
