Active video filter

Originally, video filters were passive LC circuits surrounded by amplifiers. Smaller, more efficient designs can currently be achieved by combining the amplifier with an RC filter. Sensitivity analysis and predistortion methods developed in the 1960s have, moreover, overcome the poor performance that gave early video filters a bad reputation.

High performance 1-Wire network driver

This document describes a microcontroller-based 1-Wire® master interface for reliable operation of small, medium, and large 1-Wire networks. This is accomplished using careful impedance matching, intelligent (software-controlled) active pullup, and slew-rate control. Software flow charts are included to assist the user in generating the correct 1-Wire timing for reset pulse, presence detect, write one, write zero, and read time slots using any suitable microcontroller. Scope traces illustrate the timing performance of the driver as well as transmission line effects as they appear with long cables.

Use of MAX4090 with reconstruction filter

In most video applications, the video signal generated from the DAC requires a reconstruction filter to smooth out the signal and attenuate the sampling aliases. The MAX4090 is a direct, DC-coupled output driver, which can be used after the reconstruction filter to drive the video signal. The driving load from the video DAC can be varied from 75Ω to 300Ω. A low input impedance (< 100Ω) is required by the MAX4090 in normal operation, special care must be taken when a reconstruction filter is used in front of the MAX4090.

Tool changing manipulator design

The manipulator is the main tool for exchanging tools in the automatic tool changer. It is responsible for sending the tools from the tool magazine to the spindle, and then returning the used tools from the spindle to the tool magazine. The design idea is to use the movement of the manipulator to change the tool of the machining center. The rotation of the manipulator is realized by a rotary pneumatic cylinder or a rotary pneumatic cylinder, and its power is realized by the drive system. The automatic tool changer of a machining center is usually composed of a tool magazine and a manipulator. It is a symbol of the machining center and a key link to the success or failure of the machining center. Therefore, all machining center manufacturers are working hard to develop automatic tool changers with fast action and high reliability in order to achieve good results in the fierce competition. Automatic tool changers are the core content of machining centers, and each manufacturer is keeping it secret. Very little relevant information is disclosed, especially the robot part. The knife extraction and knife insertion actions of the manipulator are mostly completed by the pneumatic cylinder or the action of the pneumatic cylinder. The entire manipulator is composed of a mechanical arm telescopic mechanism, a mechanical claw opening and closing mechanism, a rotary mechanism and a linear motion mechanism for loading and unloading tools.
