It takes considerable time and effort to manufacture “perfect” surfaces. The mirrors on NASA’s James Webb Space Telescope, with a surface area of about 25 m 2 and finished to accuracies of 25 nm, took ...

High feedback loop gain is one of several critical parameters frequently needed for precision servo drives in automation equipment, robots, handling systems, machine tools, and various production ...

Direct-drive systems are firmly entrenched in the semiconductor and electronics-manufacturing industries, and are becoming increasingly common in the machine tool industry. Direct-drive systems offer ...

Controlled servo drives are used in many areas of automation technology, converting, printing, handling, and robotics, including production machines and machine tools. The selection of a rotary ...

Optical encoders have been used to measure position, speed, acceleration and motion direction for decades, but now they are finding new applications where high performance and miniaturization are ...

A high-accuracy 20-bit resolution quasi-absolute encoder with DSP-based signal processing is housed in a dc stepper motor assembly, as shown in Fig. 1. Able to operate in a temperature range between ...

Controlled servo drives function in many areas of automation technology, from robotics and handling systems to the drive technology of production machines and machine tools. The requirements of speed ...

Motion blur can be caused by interpolating frames, algorithms can help with this problem. The BBC has always pushed boundaries to achieve better video quality for both streaming and broadcasting - one ...
