Method of Driving a Field Emission Display

This technology makes possible Field Emission Displays (FEDs) and Surface-conduction Electron-emitter Displays (SEDs) that can use a variety of less expensive cathode materials and types. The technology adjusts the output of the cathodes by using a monitoring circuit between the cathode and the anode (the visible phosphors), overcoming the poor picture quality that can result from emitters operating at different levels of effectiveness. With this technology, almost any kind of cathodes can be used in making display panels that have image quality as good as display panels made from carbon nanotube (CNT) cathodes, thus reducing manufacturing costs.

Gel That Changes Color on Demand Could Lead to New Sensors

Researchers at the Massachusetts Institute of Technology (MIT) have created a new structured gel that can rapidly change color in response to a variety of stimuli, including temperature, pressure, salt concentration, and humidity. The gel could be used as a fast and inexpensive chemical sensor. These environmental sensors could be used in food processing plants, where it would indicate if food that must remain dry has been exposed to high levels of humidity.

MV1000 and MV2000

Yokogawa Electric Corp., Newnan, GA, has introduced the MV1000 and MV2000 paperless portable recorders with integrated display, recording, and communications functions. The units record on-site changes in temperature, voltage, current, flow, and pressure. The MV1000 features 24 input channels; the MV2000 has 48 channels. Both units feature 200 MB of memory, allowing data to be stored for approximately 70 days at one-second intervals with a 12-channel model. The recorders feature guidance messages for set-up and entering of settings. Measured data can be stored in text format on removable storage media for further processing and data backup on a personal computer using standard software. The MV1000 features a 5.5" color TFT-LCD display; the MV2000 has a 10.4" display. For Free Info .

Strainmeter Helps NASA Identify Continental Drift

TEGAM 1949-0001 ratio transformer TEGAM Geneva, OH 440-466-6100 www.tegam.com The EarthScope Project is an undertaking funded by the National Science Foundation in partnership with the United States Geological Survey and NASA to characterize the geology of North America, including continental drift caused by earthquake faults. Capturing the slow movement (which in some areas happens over centuries) can be done by measuring strain. Capturing strain (the deformation caused by stress) also can highlight areas that are moving faster along a fault relative to other areas.

2007: The Year in Technology

In 2007, we focused on the global climate, and as gas prices soared, more novel technologies emerged in the development of alternative fuel and power sources. Once again, electronics and computers became smaller, faster, and cheaper, thanks to advances in nano-engineering and alternative battery technologies. Homeland security continued to be a focus of research and development in new ways to protect ourselves and our soldiers. And a number of breakthroughs in the medical field brought the promise of revolutionary new diagnostic and treatment options.
