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.
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.

delabs Notes –
This is an Educational Masterpiece, with more Relevance to Asian Students. I took my first steps with 8085, Z80 and later 8749. Then the 80C51. If you start writing code for 8080, you will want features which will come in 8749 and when you study 8749 and think of enhancements 80C51 will pop out as if they read your mind.
Once you work with these, then you can use all the new uC and uP easily. It is better you write code with as less EPROM or Flash as possible. This will help you make quality code. The smaller the code the more real time your firmware and lesser bugs.
The Intersil ICL7135 precision A/D converter, with its multiplexed BCD output and digit drivers, combines dual-slope conversion reliability with ±1 in 20,000 count accuracy and is ideally suited for the visual display DVM/DPM market. The 2.0000V full scale capability, auto-zero, and auto-polarity are combined with true ratiometric operation, almost ideal differential linearity and true differential input. All necessary active devices are contained on a single CMOS lC, with the exception of display drivers, reference, and a clock.
- Accuracy Guaranteed to ±1 Count Over Entire ±20000 Counts (2.0000V Full Scale)
- Guaranteed Zero Reading for 0V Input
- 1pA Typical Input Leakage Current
- True Differential Input
- True Polarity at Zero Count for Precise Null Detection
- Single Reference Voltage Required
- Overrange and Underrange Signals Available for Auto-Range Capability
- All Outputs TTL Compatible
- Blinking Outputs Gives Visual Indication of Overrange
- Six Auxiliary Inputs/Outputs are Available for Interfacing to UARTs, Microprocessors, or Other Circuitry
- Multiplexed BCD Outputs

The ICL8038 waveform generator is a monolithic integrated circuit capable of producing high accuracy sine, square, triangular, sawtooth and pulse waveforms with a minimum of external components. The frequency (or repetition rate) can be selected externally from 0.001Hz to more than 300kHz using either resistors or capacitors, and frequency modulation and sweeping can be accomplished with an external voltage…. The chip is available in some stores, not in production. (This is another chip of intersil i used for many things – delabs)
- Low Frequency Drift with Temperature 250ppm/oC
- Low Distortion 1%(SineWave Output)
- High Linearity 0.1%(Triangle Wave Output)
- Wide Frequency Range 0.001Hz to 300kHz
- Variable Duty Cycle 2%to 98%
- High Level Outputs TTL to 28V
- Simultaneous Sine, Square, and Triangle Wave Outputs
- Easy to Use – Just a Handful of External Components Required
Use in Phase Locked Loops – Its high frequency stability makes the ICL8038 an ideal building block for a phase locked loop as shown in Figure 9. In this application the remaining functional blocks, the phase detector and the amplifier, can be formed by a number of available ICs (e.g., MC4344, NE562).
The linearity of input sweep voltage versus output frequency can be significantly improved by using an op amp as shown in Figure 10.
A global leader in silicones, silicon-based technology and innovation, Dow Corning offers more than 7,000 products and services.
“Xiameter is a web-enabled global silicones supplier. With Dow Corning reliability, Xiameter offers more than 400 commonly-used products online”
Silicones from Xiameter – the Global Silicones Supplier
“Silicones have found use in HBLEDs for many critical needs – providing electrical and environmental protection, increasing light-extraction, minimizing heat build-up and forming lenses that provide options for specific light distribution patterns and intensities.”
Silicones are polymers that include silicon together with carbon, hydrogen, oxygen, and sometimes other chemical elements.
Frederick Kipping was the chemist who pioneered the study of the organic compounds of silicon (Organosilicons), and invented the term silicone.
You know that Silicones play an important role to electronics manufacturing. When you want to Insulate a Power Device from the heatsink, Silpad is used in place of Mica. In some situations, where a higher temperature is expected, Mica or Alumina is inevitable, but these are fragile.
Silicone shrink sleeves, Silicone Insulating Sheaths or Surfaces, provide good electrical insulation and Thermal stability to survive in the industrial environment.
Here is an example how i feel a DTH portal can interleave with interactive optical/wireless networks on land.
Let us assume Simtel has a DTH Channel. They broadcast MS updates from 10.00 AM to 10.30 AM. Linux updates at 11.00AM and Mac at 9.00 AM. All updates, some repetitive in gzip format and a advance xml feed indicating and enabling parsing of content on a digital device.
From 1.00 PM to 5.00 PM is subscriber time. “Your favorite software is ‘played’ at these times”. A user can use his phone or tablet to request a media. paid or free. All software will be broadcast at the time slot. With a xml feed/sitemap.
The user transfers the software from dth box to his computer using usb/lan. If he has been mailed dual layer decrypt keys he will be able to unzip the paid software. Else he can look thru the formatted/presented xml for any free software/media he would like to use.
DTH software providers can monetize using software developers to publicize their demo versions. Other firms from computers to toothbrush providers can give a “Media Promotion Pack” with wallpapers/freeware/video/audio/presentations and discounted/free offers.
Auxiliary Software Media DTH Download Box – Reduce Net Congestion
# Either you connect the USB of this Download-Box to Router to make a media server for your Netbooks & Tablets or plug it to your Desktop PC.
# This has a Tiny LCD Touch Screen, Key in the URL & Press Get, Wait. Media ready beep will come in a few secs. Satellite Delays don’t matter.
# Invent something like Satellite Software/Media Download DTH Service – Small dish on Roof, A Stand alone Box with One Tera Byte HDD and USB.

Idea from Polly –
Make a AI Robot in the form of a Cartoon Parakeet. Something like polly the techno parrot below. When you ask a question or a unique term like “Solar Energy” or “Vitamin C” it can use its AI – Artificial Intelligence to read out a Wikipedia Page and if not Satisfied browse the web internally and suggest alternative pages to read out. It can have a Dockable Tablet Interface too for Visualizing its AI and Articles.
Who made Polly Shown on the right in CrossSection – Rob and Roberta Radtek
“Direct from the Institute of Robotic Technology comes this amazing interactive robot pet– POLLY THE TEKNO PARROT! Polly talks with people he senses around him just like a real parrot. Polly’s electronic cuircuits can detect motion, sound, light and even touch. He will snore off to sleep at night and wake up in the morning. If you pet him, he will “coo” and move his wings. ”
