Online Security in Embedded Systems

Comments Off on Online Security in Embedded Systems

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.

Comments Off on Usability and Accessibility Enhancements

Tablets have tools for Communication, Browsing and Many Utilities. It needs to be usable by very old people and very young ones as well.  They need to be affordable and Robust too. Ability to survive falls, Grime, Water and Heat. It should be usable by people having Health issues too.

Usability and Accessibility Enhancements

Alert sounds likes chimes and rings are not enough, The Tablet must be able to yell and scream when it is far from the owner. The user needs to wear  a Bluetooth pendent with microphone .

When charge is low, it has to create a tantrum till it is fed…up. Some pricey models can have tiny wheels to move to the closest charging bunk. Some Vacuum Cleaners are able to move and recharge themselves.

When a SMS lands, it is able to read out loud and take a reply by voice and send it at once. Similarly the email could work on the tablets, all hands-free. The speakers and quality audio are on the tablet/pad and the pendent is just an additional microphone with bluetooth and vibrator with a titillate option.

Incoming  calls can move in tandem with an answering device and make loud Audio Visual Effects to get the attention of the Owner. The caller cannot wait, so the answering machine takes the call, says “please wait” and then rings the Alert Alarm Bells and even vibrates the Pendent. The Senior now can talk to the pendent and will get the caller’s voice loud on the Phone. The Phone Audio has to be very good and loud.

If the room has a connected HD Monitor, even that can be used for the communication purpose. The user just needs to click the pendent to answer a call or video chat with family friends. In Business too, Large monitors and Loud Speakers can improve communication.

Smart PowerPacks or PowerBanks+ can be the Charging Stations. The Power Packs with docks can have the wheels and intelligence to recharge the device on alert, they will also recharge themselves from the mains power, whenever required.

Expensive Phone or PowerPack Models can have Drone Mode. I say this emphatically because the Dilbert Dupey develops wings after the mutation, This indicates that quad-copters, drones were predicted. It could be that, One fine Day the Tablet+ may Fly!

Comments Off on Wireless Home Automation and Application Server

The PC has much Evolved, From XT to AT, then from 286 to 586, the evolutionary trend continues. The Speed: GHz, Space: GB and Software: Linux-XP, have grown rapidly. The other vital things Interface, Networking and Power Consumption moved a bit slower. So some suggestions on the New Desktop for Small Office and Home Standard, that is crucial in the present computing scenario.

Enterprise Level Hardware and Software can be extrapolated from this idea for a SOHO. An Enterprise is like a SOHO Cluster. One big Homogeneous Entity is unstable and unreliable. When small varied, self-dependent entities collaborate to form an Enterprise, it is a Cluster of SOHOs, which is a Reliable and Resilient Entity.

Wireless Home Automation and Application Server

A Green solution could be New Desktop Computing Standard – The quiescent losses in this is only the wifi server cube, which can serve 6 tablets or UMPC. So if 6-12 people are using computers, many desktops need not be on. Tablets, Laptops and Notebooks consume less power and run on batteries. Thin Custom Notebook and Tablet Clients can use one OpenOffice on the WiFi Application Server cube

Nomadic Computing – WebOS – 2004

Nomadic Computing - WebOS

SOHO Desktop Standard

  • The Desktop Home Computer is the Wireless Router, Power Server.
  • SMPS Power Supply runs Both on 230V-110V AC and 12-24 V DC.
  • Home Wifi Computer, Application and Web Server is just a Cube.
  • Wireless Networked Peripherals, Printers, Drives, Viewers, Inputs.
  • Desktop Wifi Server networks 6 Handhelds and 12 peripherals.
  • Wireless Ethernet LCD Monitor-Keyboard for System Admin.

Tech Ideas as Feedback – Computers

Comments Off on Tech Ideas as Feedback – Computers

These are some ideas, comments, feedback and communication that i have had over the past many years online. 2006-11

Photonic Speeds

The real speed can be seen when we switch completely to photons and photonic circuits. No more electrons. Blazing Tera Hertz Transfer Speeds. Just a few decades away. Another smart alec comment i made at the site of a major speed provider.

System-on-Chip – SoC – IP

3D Hologram Newspaper

3D Hologram Newspaper

An Interactive 3D Hologram Newspaper that is Projected by a Small Rechargeable Pendent or Desktop Device. It can be a MultiMedia 3D Book, Magazine or Newspaper. It can be used even when lying down on a bed. It can be used on a Restaurant, the group can read the day’s Paper. (An idea i gave at a website with a Questionnaire, years ago)

Digital Signal Processing – DSP

Rechargable Wireless Peripherals

Buy only those Wireless Peripherals or Even Keyboard / Mouse, that can be recharged & dockable or on a Ferrite / Magnetic, No wire/metal charging base. (Just drumming up an old idea of mine)

Storage Tripod Hybrid for Reliability Speed

Comments Off on Storage Tripod Hybrid for Reliability Speed

The wear and tear, fragmentation on HDD can be reduced using a Tripod Hybrid. Access Speed improves too…

Top Layer is RAM Drive with Li-ion Battery. Second layer is Flash. Third is the Spinner HDD.

All active files of user are on RAM drive and backed up on Flash by intelligent Drive (not CPU). The files go into HDD after they have been stable for over an hour. As HDD sizes are increasing. The files and file system can be like svn and maintain 3 versions of all dynamic files. This is useful for user also and HDD too.

Storage Tripod Hybrid for Reliability Speed

Static files like Binaries can be on one area of HDD. Frequently accessed binaries are promoted to flash layer. Extremely frequent to Ram Layer. The HDD now is less stressed and lasts longer and is a stable backup. Power failures immune.

Bare Essentials

A supercap built into a HDD. On Brownout OR Power Fail. The falling ramp is detected beyond an isolating diode. It says to HDD uC … Look there is something funny with power now. The HDD uC at once finishes the work at hand, drawing its juice from the stable supercap, parks its heads and goes to sleep.

When power is stable again, it wakes up and the supercap is replenished too. This way damage to HDD is avoided, these happen when .. battery connection problems in laptop or mains power fluctuations or switching power systems carelessly. It makes HDD idiot proof at least electrically.

Speech to Text and Text to Speech Devices

Comments Off on Speech to Text and Text to Speech Devices

This was an idea for Apps like Browser and Email..This is for any device phone or laptop a user interface for people who need it like when Cooking or Driving. People with disabilities or injuries. BlackBerry Phone had a nice incorporation of the text to action.

Added in 2015

We have three things Text-2-Speech, Speech-2-Text and Speech-2-Action. This makes any Gizmo or Computer Interface with a Human without the use of Limbs.

2009 Note Below –

Spoken Words or 14 Seconds of Voice Message. Alternative to Thumbing. A Text to Speech Engine Server Side. With Adaptive Mimicry Voice Synthesizer for that User ID. .

A MultiMedia Service without too much local or server load. Short Compressed Audio Files Recorded and Rendered by Flash Inline Inserts on the Web Application.

Speech talking calculator by Telesensory Systems

 A Vintage Speech Equipment The Speech+ talking calculator by Telesensory Systems, Inc.

First idea enables people who just cannot type their message, and need to speak a few words, which is recorded by microphone and sent like a Compressed Voice mail.

Second Idea depends on first idea to train a server side engine, a Text to Speech tuned by earlier voice messages.

When a person cannot read the text, like when driving or in a private gathering, he can press read all incoming messages. Then the server will process text to speech matched according to the User ID Speech Profile and Read out loud in his Headphones.

Date Time Clock Widgets

Comments Off on Date Time Clock Widgets

I wanted to realize usability of controls within a small footprint. This lead to some innovations.
These are JavaScript and CSS Clock Widgets originally made for my webpage later improved and decorated for iGoogle. Now available as web widgets.

Date Time Clock Widgets

Date Time Clock Widgets

When i found the Remote controls and the early mobile phones difficult to use. I felt i have to try to design user interface within a small footprint. This helped me innovate a Active or Dynamic GUI concept; as shown in the Ability to change the skins of the Audio Music player and Digital Alarm Clock. The metronome too see the other project in this profile. These were done around 2005-6-7. Both for elements on my site and gadgets.

Digital and Analog Clocks

I also made a Virtual Web Gadget Alarm Clock Simulation that will demonstrate a Dynamic GUI in a Limited Facia Area.

Conclusions –

Reduce the number of operations a user would do at achieve a purpose. Auto, Intuitive, Context Gui. When a Customer comes to buy Trousers, Take him to the Trouser Corner. Do not show Tuxedo option. The colors have good contrast and the text clearly visible.

A Highlighted reaction to user action. Tactile. Dynamic GUI, see in Gadgets above. GUI Elements appear only for that sequence of actions. No clutter. Menus if used, should not get stuck. Should not be fidgety, should not be menus at all if possible.
