NWUAV MEMS Fuel Injection System

CurtisEllzey — Thu, 29 Oct 2009 13:45:00 GMT
The NWUAV MEMS Fuel Injection System uses Hewlett Packard Ink Jet technology to atomize a variety of fuels including JP5, JP8 and logistical fuels used in internal combustion engines. The system will allow longer duration flight times and reduced (green house gas) emissions as a result of the ability to digitally control the fuel delivery and droplet size to a level much smaller than is conventionally possible using carburetors and COTS (Commercial Off The Shelf) fuel injectors. For more information, visit NWUAV Propulsion Systems.

Westech Solar Integrative Controller

CurtisEllzey — Wed, 28 Oct 2009 11:50:00 GMT
The operation of a Westech solar collector is as follows: Solar radiation is absorbed by the evacuated tubes and converted into heat. Heat pipes conduct the heat from within the solar tube up to the header. Water is circulated through the header via intermittent pump cycling. Each time it circulates the temperature is raised by 9-18° F and throughout the day the water in the storage tank is gradually heated. The system operates automatically by using Westech's intelligent controller, detailed here. For more information, visit WesTech Solar.

Westech Solar Collector Systems

CurtisEllzey — Tue, 27 Oct 2009 13:20:00 GMT
The Westech Evacuated Tube Solar Collector is a device that absorbs thermal energy from the sun and converts it into usable heat. The heat is normally absorbed by water, or a freeze resistant water mix, which can then be used to supplement hot water heating, space heating and even space cooling via use of an absorption chiller or desiccant cooler technology. For more information, visit WesTech Solar.

Westech Evacuated Tube Solar Collector

CurtisEllzey — Mon, 26 Oct 2009 12:02:00 GMT
If you’ve ever used a glass lined thermos, you know that a vacuum is an excellent insulator. Evacuated tubes absorb solar energy and convert it into heat for use in water heating. The insulation properties are such that while the inside of the tube may be up to 300° F, the outer surface is cold to the touch. This means that evacuated tube water heaters can perform well even in cold weather when flat panel collectors suffer from heat loss. For more information, visit WesTech Solar.

SPECK.CHECK For First Article Inspection

CurtisEllzey — Tue, 20 Oct 2009 13:44:00 GMT
CGI's Spec.Check inspection software, for use with any digitizing system, is designed for first article inspection or mold qualification and can save users time in performing dimension measurements - up to 75 percent, according to the developer. In one instance, a company needed to measure an eight cavity mold with 93 dimensions per cavity -- normally an 80-hour task. With Spec.Check, the job was completed in less than six hours. For more information, visit CGI Inspection.

CGI Cross Sectional Scanning

CurtisEllzey — Mon, 19 Oct 2009 12:04:00 GMT
First article inspection is an essential and crucial step in product development and in proving a new mold. But when the part geometry is complex – and especially when the internal geometry is complex – the measuring and qualifying process can take days, if not weeks. This is unacceptable in terms “time to market” as well as in terms of “cost.” The CGI System and Spec.Check solves these problems by providing complete measured results in one to two days instead of the weeks that others processes require. For more information, visit CGI Inspection.

A160T Hummingbird - Part 2

Terry Knight — Thu, 15 Oct 2009 12:00:00 GMT
The A160T Hummingbird unmanned aerial vehicle looks like a helicopter but is unlike any other helicopter on the market today. It features a unique optimum speed rotor technology that enables the Hummingbird to adjust the RPM (Revolutions Per Minute) of the rotor blades at different altitudes and cruise speeds. During flight, an operator can vary the RPM of the A160's rotors (speed them up or slow them down) at different altitudes to improve overall efficiency and save fuel. This is quite a departure from conventional rotor systems, which tend to have a fixed rotor RPM regardless of altitude. For more information, visit Boeing.

EOS Laser Sintering Systems

CurtisEllzey — Tue, 13 Oct 2009 14:19:00 GMT
EOS systems enable a wide variety of e-Manufacturing applications for producing metal or plastic parts. e-Manufacturing with EOS technologies is a method of manufacturing by which parts for consumer goods, industrial components and tools are laser-sintered directly from electronic data. A laser selectively melts and fuses together plastic or metal in powder form layer by layer until, after the final layer has been applied, the completed product is removed from the machine. For more information, visit EOS Electro Optical Systems.

EOS Laser Sintering Technology

CurtisEllzey — Mon, 12 Oct 2009 12:00:00 GMT
Laser sintering is a generative layer manufacturing technology. Any three-dimensional geometry can be built effectively and flexibly, without any tools or laborious milling path programming. During production, the 3D CAD model is sliced into layers. EOS's innovative laser-sintering technology then builds the required geometry layer by layer. The energy of a laser solidifies powder-based materials, for example plastic, metal or foundry sand. The laser-sintering process allows for the production of several different parts in one single build job. For more information, visit EOS Electro Optical Systems.

Yamaha AvantGrand Piano - Part 2

Terry Knight — Thu, 01 Oct 2009 10:33:00 GMT
Amongst the AvantGrand's many innovations, the placement of the four-channel, three-way Spatial Acoustic Speaker System mimics the points where original grand piano samples were taken, while a Soundboard Resonator creates a non-directional sound dispersion directly in front of the player, duplicating the subtle reproduction of the buildup of sound felt by concert pianists. These technologies combine to authentically re-create the depth of tone of the Yamaha nine-foot CFIIIS grand piano, the choice instrument of many of the world's top musicians and performance venues.
