Protect your Design or IP

If you have made an electronic product with a new circuit or code and need to protect it, then these are some Methods. If your Intellectual Property is an Idea, A Hardware Innovation or Software Application; It may need some protection other than patents. Sometimes patents are used for general applications and generic designs. Patent only an Original Idea or Innovation or an Exclusive and Unique Method.

Microcomputer Circuits in Process Control.

Protect your Design or IP

If you are small and the innovation very big, tie up with established companies with reputed brands. If you are a source for a certain product component or module, make certain restriction on patenting products made from it. Else, your Module or Application Sales may be jammed by Panic Patents.

That is the reason, the Platform that fosters innovation is Open Source.

1. Security Bit -

Use for digital logic area, an atmel uC with security bit protection or any uC-uP with internal memory read protected with security bit. the firmware should be kept in tight control from both external people and your employees and must be on a non-networked and non-internet machine.

2. Hermetically seal -

This is a crude and ancient way, delete the chip part numbers and pot it in a plastic can with ciba araldite epoxy with alumina filler, this way product may not be copied and it will be immune to vibration and corrosive environment. but heat dissipation and serviceability is affected, so make a epoxy potted module of only some part of the circuit.

3. Make ASIC or FPGA -

ASIC is only for volume production and is copy protected, if you design in-house and the chip maker you order is trustworthy, then this is ok, for small volume production use FPGA, CPLD, DSP uC or uP with read protection as practical.

Embedded Systems - More about uC based designs are here.

4. Go open source -

Design a circuit and put it on the internet to share, let the community use it and improve it, here also revenue is made by service of product, custom design and customer support and this will work long term free of tensions. This way has proved to foster greater innovation and stable technologies.

Embedded Linux Devices and Gadgets

Embedded Linux is not only Open Source, but can be adapted to any type of dedicated embedded system. It is more like a configurable firmware for Embedded Equipment. Its ability to manage multiple tasks efficiently makes it more friendly and stable, compared to any other OS.

When you look at the History of Operating Systems, you will see that that an OS that meant serious business was UNIX. It was the anvil for the creation of the C Language and AWK. Now we have Linux, the evolved Unix like OS, which is comfortable and versatile for Networking and Clustering.

Here is a Embedded Linux Wiki for the embedded product design community.

Gadgets and Appliances are become increasingly complex. More memory and CPU power for small devices are commonplace. Linux is one OS that can be muntzed to the smallest size. This helps developers make something like a super-firmware. Just what you need for that device, can be the OS.

Touchscreens for Home Appliances, wireless networking and web enabled consumer electronics make Linux an excellent escalation from "Firmware". For tiny systems a firmware is the OS. For complex devices today, Linux is user configured firmware.

Surgical Tools useful for Manufacturing

Long ago, i was making and supplying some hybrid electronics to some firms. The soldering and handling required some tools and custom jigs which were designed. As the product was mass produced, some tools for managing and working on Tiny PCB's and parts were not available in the market.

Electronic Product Production Manufacturing

So a affordable solution was created, the jigs were supplemented by surgical tools. These are the Clips and Tweezers that a doctor uses when he conducts an operation.

Surgical Tools useful for Manufacturing

Let use see one here an Hemostat Clamp and other tools at P J Tool and Supply

Call it Forceps, Tweezers or Pliers. These tools, both the bent/arched/curved one and straight are useful.

When you go to a Surgical Supplies Store, Buy some Filter Paper, capillary tubes and a spirit lamp as well. These can find a lot of good use in the ultimate quest for the God Particle. Beat the Swiss to it.
