Internet and Intranet of Things - IoT

When Intelligent Devices (embedded systems) are privately and securely networked, it is called the Intranet of Things. This is like a Home-Office-Business private closed Cloud. This is ideal for Home and Infrastructure Automation and even Big Business or SMB Automation.

The Internet of Things - IoT is the Superset. It could be Secure and Private but still vulnerable to security lapses and breakdowns. This could send devices, robots and machines Berserk.

In all Networked Environments we have to have fallback arrangements when network fails or is compromised or even slow due to peak hour internet traffic.

Internet and Intranet of Things - IoT

WSN - Wireless Sensor Networks and M2M - Machine to Machine Data Communication;

M2M and WSN is a closed private Intranet network that is used in Manufacturing and Industrial Automation. Here we could use data sync to Interface it with the Web or Internet. This enables passive controls and monitoring of SCADA or Machine Status, yet very Secure.

COR - Collaborative Online Robotics - This is like team work for bots. Big tasks can be accomplished by very small and weak robots. Example - Observe Ants and Bees.

All these only mean Wireless Networked Intelligent Embedded Systems. They could be machines, appliance, robot or gadget. The brain is both on the device and in the Clouds.

Wired Wi-Fi or WiGig for enhancing Range

You have a big office of 3 Floors or a Home which is not Wi-Fi Friendly and it does not have the provision for LAN or any other wiring. Even a distant room/garage or basement beyond the Wi-Fi range.

Wireless Gigabit Alliance - WiGig 60 GHz

If we could build a Wired interface for Wi-Fi and WiGig then such rooms can be brought within range. A wired interface without wires, then you think of optics, not even optic fiber .... that will build up the cost for home networks.

Wave Guide may be an answer, a wire that pretends to be a waveguide. Let us take a thin flexible plastic tube, 2-3 mm in dia, 1mm wall thickness of tube. The outer wall of the 3mm tube is coated with a suitable copper alloy. Above that a thick insulation to protect from mechanical damage. This may act as a waveguide if properly designed, probably the way or pattern in which the metal is coated.

Wired Wi-Fi or WiGig for enhancing Range

Fixed WiMAX SoC and RF Module - Fujitsu

If this works in theory, then Pump RF on one end with a little more juice, just like in Optic fibers. The other end may get enough signal strength for good speed connectivity. It will at least be still wi-fi on waveguide and easier to implement than RJ45, these LAN cables, connectors and switches include many components and modules, that make it very fussy and unreliable.

Wi-Fi seems to be very friendly and safety has also improved now. So a wired, one wire or waveguide to extend Wi-Fi can phase out the RJ45. I like RJ45 similar to the sentiments i have for the Printer Port and RS232. Then USB has just taken over. Change is inevitable, Find a way out of RJ45 for good.

Automobile Ideas from 2002

Simple Automobile Safety Radar

There must be a very affordable automobile radar with just a 10-20 feet radius around the vehicle. This should display as a graphic on the dashboard as some of the very old 2D car games. This radar must be based on sonar or infra red to avoid additional EMI-RFI pollution and confusion. The display should show all objects which include people, small animals, kerb and wall.

The sensor has to be a multiple sensor, static belt one near wheels and one at the roof of automobile. The display device on car should be TCP-IP so that you can monitor your vehicle with your cellphone, PDA or any browser.

Cars can have multiple skins like Winamp

If you use organic flexible LEDs, encapsulated in transparent poly-sulphone or some silicones. And the RGB triad matrix of LEDs are driven by a computer system to make it work like a flexible LCD screen. It can be used to form a skin for a car. Only there will be no high resolution, but it will do.

This flexible layer is fixed on the car like a permanent cap. Now with the onboard graphics synthesis embedded car computer you can choose any jpg, png or gif textured tile or make your own. Then output the tile or wallpaper to the car exterior LED matrix skin. Now the Car has become skinnable. Not just colors but fine textures are possible.

Automobile Ideas from 2002

Now with a Bluetooth enabled Human Mood Monitor plugin you can make the car exterior to reflect the mood of the life-forms inside. This will make a road alive and traffic jams very colorful.

Some things i had written online around 2002 on cars.

Microcontroller - 8051, 8052, OpCodes, Analog Interface.
