Texas Instruments – wiki

TI produced the world’s first commercial silicon transistor in 1950, and designed and manufactured the first transistor radio in 1954. Jack Kilby invented the integrated circuit in 1958 while working at TI’s Central Research Labs.

TI also invented the hand-held calculator in 1967, and introduced the first single-chip microcontroller (MCU) in 1970, which combined all the elements of computing onto one piece of silicon.

A Developer Evaluation Embedded System

Texas Instruments Embedded Portfolio Overview is made up of three sub-divisions: Wireless, Microcontrollers, and Processors

Embedded processors are the processing brains of electronics that gather inputs from analog chips and perform computational processing to operate a system.

The gEDA project is working on producing a full GPL’d suite of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production.

gEDA – Electronic Design Automation

Currently, the gEDA project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.

gEDA - Electronic Design Automation

gschem is the schematic capture program/tool which is part of gEDA. Its sole purpose is to facilitate the graphical input of components/circuits.

PCB is an interactive printed circuit board editor. PCB offers high end features such as an autorouter and trace optimizer which can tremendously reduce layout time. For custom requirements,

GTKWave

Icarus Verilog is a Verilog simulation and synthesis tool. It operates as a compiler, compiling source code written in Verilog (IEEE-1364) into some target format. For batch simulation, the compiler can generate an intermediate form called vvp assembly.

GTKWave is a fully featured GTK+ based waveform viewer. GTKWave is designed to handle many signals at once, it has three signal searching modes (Regular Expressions, Hierarchy, and Tree) as well as the ability to display data in many different formats.

Cars should be aware of their environment and display status in the dashboard. It is like having cameras all around. The objects around and their direction of movement and acceleration.

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.

Automobile Ideas from 2002

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.

Microcontroller – 8051, 8052, OpCodes, Analog Interface.

(:->)—-\–/—-< Man Sleeping

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.

An Alarm Clock with Musical Alarms. This Web Widget was for the iGoogle Homepage, A Web-page or even a blog.  It was an Experiment in User Interface in small a small Facia or Front Panel.

You can set Five Alarms with Ten Selectable Musical Sounds and a small Text memo.- 2005

Digital Alarm Clock Gadget

The Project Page digital-alarm-clock

The simulation is as close as possible to a uC based Clock which you could build, The GUI is more like a electronic gadget than a Software Application. That should charge you to build your Alarm Clock today.

Eco Green Alarm Clock with Flash Sound

Get news Eco Version above, This page is of the Older Version of Digital Alarm Clock. The reason this is old is it sound integration is not very good.

Usability and Ergonomics Research

This gadget has established usability problems. The were intended and demonstrated. It was an attempt to show the limits and strain associated with push button and key controls to operate an electronic equipment.

Many Apps, Appliance and Gizmos are constrained with a small control interface size, these pose a challenge for the User Interface design. I myself have problems with the keyboard phones and remote control. This can be seen even in the puzzling Monitor OSD controls in comparison to the easy analog Pot controls of old CGA/EGA Monitors.

Controls should be easy like the water tap or power switch. Not like a Puzzle, Maze or Quiz.

Technology needs to make things simple. Keep controls minimum and Human Friendly means (analog). A human Being is a “Real Time Analog Machine”. This gadget is a continuing experiment in ergonomics.

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.
