ELECTRONICS: Dytran Instruments recently release a new signal conditioner designed specifically for airborne flight testing. Model 4139 is a six-channel signal conditioner designed to power up to six IEPE constant current type accelerometers while adding filtering, output biasing and output limiting to present signal overdriving. The 4139 is intended for flight test use and operates from +28V dc aircraft power. This miniature package measures 6.25 x 4.00 x 1.03 inches and weighs about ¾ lb.
The input power, output signals and power to the accelerometers are interfaced by one D-subminiature multi-pin connector. The accelerometers are connected to the 4139 through six 10-32 jacks. A nominal +2.50V dc offset is provided at the output. This allows for direct connection of the output signals to telemetry transmitter modulators which are designed to receive input signals over the range of 0 to +5V. The output signal positive swing is limited to +5.6V to avoid the possibility of overdriving the signal from one channel into the range of the adjacent channel. The 4139 has four mounting holes at the corners to accept #10 mounting screws for easy installation to the airframe.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
