Electronic Design Automation

EDA domain is purely in software. It is how software are used to help integrated circuit (IC) designers to design ICs. These software are referred to as EDA tools.

While the high level stage of the IC design requires a lot of creativity, but the low level and details part of IC design can be very repetitive, tedious and boring. The EDA tools help the designers in doing the repetitive and tedious tasks.

While in collage, students majoring in electronics learn basic electronic system design using small number of components called gates. Basic system can be construct with less than 10 gates. By their final year, the students will learn how to construct larger system which consists of up to hundreds of gates. This is not how it is done in the real world.

In the real world, a system such as the Intel Pentium 4 chip is constructed from … Read the rest

Building DVR and HTPC

  • Case
    Your case is important because it is going to be sitting in your living room alongside your television, DVD player, stereo and so on. You don’t want some beige office PC cluttering up your home theater. Here you can either splurge on a custom, HTPC case or you can paint and customize your own. I went with contact paper and acrylic paint as a cheap solution to decorating a beige case.
  • Video Card
    Incredibly, your video card is a place you can save some money on your homemade Tivo. Unless you plan on playing some serious high-end computer games, all you need is an appropriate video out (s-video, DVI, or HDMI depending on your needs).
  • Tuner Card
    Make sure you don’t go cheap here. Go with a Hauppauge brand tuner card. At least the PVR-150. These are quality cards that take a load off your main processor.
  • Sound Card

Basics of VoIP

VoIP stands for Voice over Internet Protocol but is more commonly know as Digital Phone, Broadband Phone, or even internet Phone service. Simply put, it refers to using your internet connection to talk to people. The people you talk to can be across the world or even just down the block.

Although there are free programs to let your computer act like a telephone, it is more common for people to purchase specially made devices that are separate from their computers but still use their internet connections. These devises then also plug into your homes telephone wiring system. This has the advantage of allowing people to use the phone equipment they already own.

To make a call, just pick it up, dial a number and talk just like you would with a traditional phone service. It does not matter if the person receiving the call has VoIP or not, because … Read the rest

Protyping Made Easy

Prototypes are an important step in the manufacturing process. It is in this process that we will encounter computer numerical control or CNC prototyping. In CNC prototyping, a computer controller basically translates the design data and produces a 3D output of that data through a mechanical device.

This whole process has revolutionized the manufacturing process because previously, prototypes were difficult to produce because it consumed a lot of time, effort and cost to make. Now with CNC prototyping, complex 3D virtual designs by design engineers are easily translated actual 3D models with straight and curved lines easily replicated automatically. With CNC prototyping machines, producing prototypes are fast, easy and cost effective.

Now that CNC prototyping processes are available for most prototyping problems, the manufacturing process is greatly sped up. The savings in time and effort allow greater productivity by allowing design engineers to work on more with less time needed. … Read the rest

Electronic Medical Billing

Since 1997, all practices which involve patient interaction should pass HIPAA, the Health Insurance Portability and Accountability Act. Under HIPAA, most of the billing claims for the service are required to file via electronic means. HIPAA was enforced in order to prevent fraud and abuse in healthcare delivery and health insurance. While manual filing is time consuming, electronic billing is fast and accurate. With the usage of electronic billing, the rejection and denial has reduced drastically and the percentage of reimbursement has improved.

Electronic medical billing is nothing but the combination of IT and health care sector. Medical practices have been using software to manage their finances for several years. However, the present electronic medical billing programs are well known as medical management practice software. Electronic medical billing software covers a wide range of functions including tracking patient demographics, scheduling appointment, tracking billing information and insurance payments, patient’s visits, diagnosis … Read the rest

USB Flash Pen Drives

Being about the same size as the standard pen, USB pen drives, most popular added feature to date is its MP3 playback function. A lot also have an LCD display for track browsing, and audio input jack and a rechargeable battery. The newer models also offer up to 10 hours voice recording and may even come with tiny speakers for added functionality.

Further, a lot of pen drives come with card reader support for portable memory formats. Some of the newer pen drives can double as a Web cam and a still camera because they have tiny camera lenses for snapping low resolution pictures. These units also come with mountable stands and for greater functionality as Web cams.

USB pen drive applications may also be used to allow the user to save desktop configurations, documents and even bookmarks and makes for easy accessibility and transfer from one computer to the … Read the rest

LCD Monitor vs CRT Measurements

Now take a ruler or tape measure, and measure the actual image you are viewing, measure diagonally, and you will see that the actual measurement is smaller than the monitors claimed size. For example, my 19 inch CRT monitor, measuring the actual image from the bottom left hand corner of the picture to the upper right hand corner is actually 17.25 inches, or in other words, only .25 inches larger than 17 inches, if the monitor measurement were the actual viewing screen this 19 inch monitor would only qualify as a 17 inch LCD monitor. This is where the LCD measurement comes in.

LCD monitors are measured by actual viewable area of the screen. They do not have a large rounded out tube beyond the screen, it is a flat panel of Liquid Crystals behind which are a series of tube lights that shine through the color crystals to illuminate

Google’s Pixel 4

The Pixel 4 adds some more AI-powered smarts, relying increasingly on its software to determine the overall look of the final image. And while the camera has some moments where it’s truly excellent, I ran into a few growing pains as Google tries to calculate its way to perfect photos.

What’s new?

On paper, the Pixel 4’s camera doesn’t seem all that different from the hardware that came before it. The primary exception is the notable addition of a telephoto lens, which Google intends to improve performance specifically when it comes to zooming and portrait mode. The shooter’s competition, however, is stiffer this year: Apple seems to have corrected some the over-zealous HDR tech that made iPhone XS images look unrealistic and unnatural at times, and the Cupertino company promises to further improve the iPhone 11 Pro’s already-very-good camera when its detail-enhancing Deep Fusion tech arrives in the next iOS

Electronic Personal Organizer

Early versions of these electronic personal organizers had features like an address book, pocket calculator and a calendar. The electronic organizer, being pocket-sized, was more portable compared to the traditional organizer, which made the former more convenient.

Now, electronic organizers are available in all sorts of sizes and have many functions and capabilities. Cheaper electronic organizers are smaller in size, or have less functions. High-end electronic personal organizers are built like mini-computers, with a memory storage large enough to accommodate huge files and loads of data. The HP iPAQ 111 (Hewlett Packard) and Palm Tungsten Handheld are just two examples of the many models and brands of electronic organizers. The two are both equipped with Bluetooth technology, WiFi capacity, as well as the capability to create Word and Excel documents, PowerPoint presentations, photo sharing and music streaming. PDA is the term used to call high-end electronic organizers.

Automotive Electronics Plug

Some gadgets and gizmos, like nose hair trimmers, could easily disappear without much fuss. There are many intelligent tools, on the other hand, that make our lives more convenient and safer on a daily basis.

Our enormous world of “smart” technology is ruled by new automotive electronics. Anti-lock brakes, electronic stability control and other indispensable features are excellent examples of smart and safe automotive electronics.

Through recent developments within the automotive industry, there has been a huge increase in the number of electronic devices installed at assembly plants. Here’s an example of how quickly cars have evolved electronically: the Apollo 11 traveled to the moon and back again, using just 150 kilobytes of onboard memory. Today’s typical CD player, however, uses a whopping 500 kilobytes of memory just to keep our favorite songs from skipping. That uninterrupted music is an iota of how electronics impact a car’s performance to benefit … Read the rest
