Switches in Electronics

Switches are electromechanical devices. The are used to control the  path of current or energy flow. Power switches are used to turn on and off loads. The contacts should be robust and have immunity to  sparking and corrosion. Switches for signals need to be gold plated for low contact resistance and within a sealed enclosure.

SoC the System on Chip and IP

When a product has to be made small, the board real estate is limited or it has to be manufactured in large numbers.... SoC is the Answer. A Microprocessor evolved into a Microcontroller by packing many external chips into one chip. Now uC Card along with the other blocks like A-D, Port Drivers, Networking elements, Display Driver and other peripherals can be packed into one chip.

Some Power Supply and RF blocks cannot be easily added inside as they have a silicon processing more specific to their applications. Laser trimmed Instrumentation Op-Amps, high accuracy resistor arrays, high value capacitors, magnetics and supporting chips are placed outside on the PCB.

The SOC can pack Digital Chips, Memory, A/D, D/A converters, uC, RAM and Custom programmable areas. For more specialized communications, analog and power requirements; Special SoC types can tackle RF and Power management within a chip because of proprietary silicon processing expertise.

Product Safety and Ergonomics

Ergonomics and Manpower the Engine of Growth

A Worker in One Firm is a Customer for another Firm. Healthy and Safe Workers implies a strengthening Consumer base.Just imagine what wonders it can do for the economy, when you broaden your view, think togetherness, as a Whole; not in isolated competitive groups, not in parts.

 

Ergonomics reduces Worker Stress. Helps in keeping good Mental and Physical Health. Safety is very important. His Limbs, Eyes and Ears are assets that a firm hires. On this page you can start learning these aspects. A good Manager knows that Manpower is the Foremost Asset of any Company.

Product Safety

  • Product should not give even the lightest shock, Even metal parts on user side to be laminated.
  • High energy circuits never enters analog and digital circuit areas without Opto or other Isolation.
  • Gadgets, Furniture, Tools and Storage Units should not cause injury. Rounded Edges, Non Toxic.

USB Serial Interface

There are many Serial Data Devices that means those that use the RS232 (old mouse port). USB is now the standard interface in most computers and embedded devices. Many mini embedded sensors and devices come with High Speed Serial Interfaces.

This page lists solutions and methods to get These Devices talking with your computer. The focus will be HandHeld Computers made of the Android OS. This way you can get your hand on the Real World thru USB and Serial. USB to parallel also helps when you want to control a Relay or Solenoid Array. Wireless Interfaces also are a good Solution with Networking.

Digital Signal Processing - DSP

When you are trying to arrive at a complex Embedded Systems and Communications solution, You will think of a DSP. Now that computers and embedded devices are used in most electronic devices, DSP is a way you can process, transform, analyze and generate fast analog data, in Real Time.

Real Time ideally is instantaneous or in sync, in tandem. Not an Zepto Second lost. But in the real world many analog inputs or result outputs can be processed a lot slower. So it is more like, How 'real time' you want, how cost-effective a real-time solution can be provided. If the analog input is slow and the system inertia is high and the user response time is limited by his persistence of vision, you need to make a system just a bit faster, even Microseconds delay may be fine. In yet another case it may be pico seconds.

Embedded Systems Design

An Embedded Microcontroller or DSP system is made of Chips, Circuits and Firmware. The digital voltage levels, speed, bus width, fan out, power consumption are some factors that a designer has to keep in mind. As portable and wireless gadgets are becoming more popular, RF, Ethernet and Energy Efficient Design aspects should be studied. Power electronics and Analog Circuits knowledge is used around the system, all this is integrated to make an instrument, equipment or gadget.

Analog OpAmp Circuits

Operational Amplifiers With a few Op-Amps and a regulated Power supply, many Instrumentation and Process control equipment can be designed. The Human Brain understands Numbers, Quantity and it regulation very well ! On the right you can see a analog controller based on opamps and discrete devices. A Heater, Fan and Motor is regulated, controlled and timed for a process.
