Tablets Slates to rule

Tablets and Slates based on OpenSource OS. Even OpenHardware Tablets. This is a collage of various blurbs of mine in my other pages.

Ultra-Mobile PC - UMPC

Tablets Slates to rule

Why Tablets ?
  1. People want computing to be Personal and Portable and hassle free. With less Maintenance Tasks.
  2. Low Power or Green is the order of the Age, Fuel and Energy is not as easy, expensive and depleting.
  3. Low Carbon Footprint, The global carbon footprint of making, selling and scrapping tablets is low.
  4. The Technologies have evolved in Flash, Battery, CPU, OS, GUI, LCD, SMT and most Electronic Parts.
  5. Online - Web Computing and Cloud Computing offers Safer Storage and Powerful Web Applications.
Most Important Specs. - Low Power, Wireless, Portable, Safe, Simple. The Browser is the Most and Only Important part of this Computer.

EDA and Product Design Ideas

I saw devices that are like Tablets. Handhelds, Nettops, Smart TV Computers. Low Power and enable to use the Internet on TV or any Display Device. Android is a nice Gadget OS, customise it to make your own device.

Chumby Mini Embedded Computer

These are types of the Chumby Mini Web Computer, it was a Web Widget App System with Touch Interface. Innovative System ahead of its time. It manifested in 2006 before the Touch Screen Tablet.

Success of iGoogle in 2005 with Mini Web Apps and a Free App Store like System. The Desktop widgets of Yahoo, Google Desktop Search who created a Apps Shop or App Vending Store formed the ideas.

These innovations and rapid Hardware size shrinking, low power chips, flash+, wireless and broadband technology boost have lead to the Tablets you see today,

I made this post today when many facts feel in place and i came to the conclusion that the Tablets, AppStore manifested from the concepts of touch usability, widgets etc. that came from gadgets like chumby and web services like iGoogle, both are gone today - 2012 delabs

Desktop Power Supply Immunity

Make the desktop architecture like laptop with regards to Power Electronics. I think now RAM's consume lower power. So every Desktop can come with a Li-ion Backpack based on some standard. 10Ahr 12V Rechargeable Battery. The entire Motherboard works on the 12V DC supply that uses Float Charging from mains.

Power Electronics & Solar Energy

The supply to computer is always derived from battery, the battery being constantly replenished. The charger also supplies power to computer board over the battery itself. Many lighting/inverter systems use this. The SMPS now is only a intelligent charger. Other voltage levels with DC/DC converters from that 12V.

Desktop Power Supply Immunity

Advantage -

1 - A user can easily upgrade the 12 V bus, another 12 V battery with smart charger; gives a boost of backup time. Probably intelligent batteries can come with built in float chargers, so that they can they can be bussed to form a 12v Tiny power grid for home which includes solar cells.

2 - When just the backpack is used, power fails. Harddisk, Monitor etc. sent to standby, low power mode. CPU then goes to quiescent state. The RAM keeps all data intact but goes to a low power mode. Alternatively quickly write a RAM image on a Flash Layer Built over RAM.

This makes the PC Impervious to Power Supply or UPS or other problems. Moves the desktop system to a 12 V standard. Drives desktop PC development to more Power Efficient designs.

Switching Supplies and SMPS

Easy integration into automobiles, bus, etc which have DC grid. Remote areas where no power is there. This will ensure desktops have a role in the future.

The charger SMPS has 1A charging current for Battery and 3A max for Computer. Total 4A max. A SuperCap can be added parallel to the Battery for Extra Inertia.

When power fails, in few seconds the system goes to standby. No program need to be closed. When power is restored they system comes up with windows and programs in the same positions of the last frozen state.

When a UPS is used, the system does not go down at all. The UPS just consists of a 10A Charger and a 12V 20AHr Battery. If the house has a 24V DC bus which is battery supported too. Then this can be used. As 24V is being developed as a new standard for internal power distribution. EMerge Alliance. The PCs also can move to this manageable and safe standard for homes.
