Handheld Portables

Handheld Computers on WiFi like Tablets, Portable Battery Operated Electronics.

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 Tablets.

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.

iGoogle Widgets and The First App Store

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 – 2009 to 2012 delabs

A Jpeg browser device like Digital Photo Album. It has a LCD Screen and a FM Radio interface. It costs less that $100 or comes free with 5 yrs subscription to a paper. – The SmartRadio

In the early morning it downloads the media on a built-in locked FM receive only radio.The FM newspaper station just transmits a few minutes of encrypted digital data. This is stored and static jpeg pages generated, which can be easily viewed and read using scroll and zoom using a convenient handheld device.

XML-HTML FM Radio – FM Radio enhancements

Electronic Engineering Magazines

FM radios consume less power and are affordable, now we should add a small LCD display like you have in cellphones. Xml should be frequency modulated and transmitted by fm stations in adjoining bands.

I once worked in Tek for a very short period. I got to experience the 2235 and 2465 analog scopes and their controls. The 2465 was a 400 MHz Digitally Controlled Analog Scope.

I also used the Plugin Scopes and Calibration systems that were Tek Culture and Tech contribution to the Instrumentation world, it probably evolved into VXI-PXI as uC systems took over.

delabs Web Widget and Application Interface Usability Experiments 2003-2008

I also had a chance to look at DSO/Logic Analyzers and the just developed TDS Series. The older tek analog scopes made me understand about usability and panel layouts. Many controls are inevitable in a Analog Scope with Electromechanical Interface.

In a Digital World that can be largely changed using the Monitor and Trackballs. The older BlackBerry phones are also good study for usability before Touch Screens came.

These days many gadgets with embedded systems are being used. Tablets, Netbooks and Desktop Clients. Many of these are used to make secure transactions like Banking. It is also used as a Security Device for Web Applications and Website Memberships.

The secure transaction process has improved. I know there is encryption and also the NIC number of Ethernet cards etc. I have some thought, i think i will note it here. In one sentence “Make Every CPU Chip Unique with a Unerasable ROM ID Code or Signature” this can also be tied to a QR Code.  A Firmware query spawned by a SSL TCP/IP action will return the CHIP ID which enables secure communication and device tracking overriding all user controls.

Online Security in Embedded Systems

Processor manufactures and Chip IP makers are standardized. The Secure CPU makers should obtain a license for secure CPU, which will be a CPU but with a Secure Transaction Chip with Unique Identification Code engraved within. Each Chip is unique and a replacement of CPU needs new authentication for all transactions. No two chips are made the same, the unique numbers are not on flash (like BIOS), but digitally etched-burnt with indelible e-ink. So when a person makes transaction his computer is more securely authorized. More security options like GPS in CPU for big transactions, these computers will be expensive too.
