Wilcoxon Research (Gaithersburg, MD) has introduced the 788A accelerometers that feature a sensitivity of 100 mV/g. The accelerometer is a single-axis sensor with an acceleration range of +50 g. High-frequency response measurements up to 10 kHz identify faults and improper machine operation. Typical noise is 4 mg at 100 Hz. The unit...

Duff-Norton (Charlotte, NC) offers the 1900 Series Rotary Union® that provides a rotating seal between fluids and a revolving roll or drum. Commonly conducted media are water, hot oils, chemicals, hydraulics, and air. The union is designed for very high pressure applications to 10,150 psi, and with maximum temperature ratings to 248...

A document describes a concept for an inertial sensor for measuring the rotation of an inertially stable spacecraft around its center of gravity to within 100 microarc- seconds or possibly even higher precision. Whereas a current proposal for a spacecraft-rotation sensor of this accuracy...

A sensor system was proposed that would monitor spaceflight bioreactor parameters. Not only will this technology be invaluable in the space program for which it was developed, it will find applications in medical science and industrial laboratories as well.

An electronic control unit has been fabricated and tested that can be replicated as a universal interface between the electronic infrastructure of a spacecraft and a brushless-motor (or other electromechanical actuator) driven mechanism that performs a specific mechanical function within the overall...

A flostation is a computer-controlled apparatus that, along with one or more computer(s) and other computer-controlled equipment, is part of an immersive cyberspace system. The system is said to be “immersive” in two senses of the word: (1) It supports the body in a modified form neutral posture...
