Vibration Sensors Monitor Engine Health in Latest Space Shuttle Launch

Model 7704M7 vibration sensors Endevco Corp. San Juan Capistrano, CA 949-493-8181 www.endevco.com On August 8, 2007, three Space Shuttle Main Engines (SSMEs) from Pratt & Whitney Rocketdyne lifted the space shuttle Endeavor into orbit and on its way to the International Space Station. The three SSMEs were fitted with Advanced Health Management (AHMS) controllers, using Endevco Model 7704M7 vibration sensors, to actively monitor engine health and performance.

Dash 32HF

The Astro-Med Test & Measurement Product Group, West Warwick, RI, has introduced the Dash 32HF multi-channel, high-frequency data acquisition recorder. Engineered to capture high-frequency data and transient signals, the unit records up to 32 channels to an internal hard drive at sample rates up to 500 kHz, and a bandwidth of 100 KHz per channel. The system contains 32 differential inputs that accept up to ±50 VDC. Filtering capabilities include low-pass, high-pass, band-pass, and notch filtering. It is equipped with a 15" diagonal monitor for touchscreen control and real-time data viewing and analysis. It also includes a dedicated, 250 GByte internal hard drive for capturing data, and a DVD burner for archiving data. Other features include 10/100/1000BaseT Ethernet for data upload, and a USB 2.0 port for archiving to external devices. It operates on 120 or 240 VAC, and includes a capacitive backup for proper shutdown without data corruption if power is lost.

Simulation Reveals How the Body Repairs Balance

When your brain’s neural pathways are impaired through injury, age, or illness, muscles are deprived of the sensory information they need to perform the constant balancing act required for normal movement and standing. In a project designed to build robots that can balance like humans, researchers at Georgia Tech and Emory University have created a computer simulation that sheds new light on how the nervous system reinvents its communication with muscles after sensory loss. The project could help better diagnose and rehabilitate patients with balance problems by retraining their muscles.

Phil Neudeck, Electronics Engineer, NASA’s John Glenn Research Center, Cleveland, OH

The Aeronautics Research Mission Directorate at NASA's Glenn Research Center has developed a new silicon carbide differential amplifier integrated circuit chip that may provide benefits to anything requiring long-lasting electronic circuits in very hot environments. The chip exceeded 1,700 hours of continuous operation at 500ºC - a breakthrough that represents a 100-fold increase in what has previously been achieved. Phil Neudeck is the team lead for this work.

Image Sensors Decades Old But Not Yet Mature

There’s no rule that says when a technology becomes mature, but one might think that image sensors would be by now, 40 years after their conception. Nothing could be further from the truth. After decades of use in fax machines, scanners, and camcorders, image sensors are now in the largest growth period in their history, and much of the innovation is still happening.
