Frequency Counter - Giga Hertz

"Imagine you have a radio receiver and you wish to display the receiving frequency. As you know the oscillator in a radio receiver works 455 kHz or 10.7 MHz above the receiving frequency. The 455 kHz and 10.7 MHz difference is called IF (Intermediate Frequency)."

Tizen was MeeGo who was Moblin or Mobile Linux

Moblin hosts the Mobile & Internet Linux Project which is an umbrella, open source project focused on the development of Linux for Intel-based devices.

"To this purpose, moblin will host various projects that will provide key elements of community-based projects such as Ubuntu Mobile and Embedded Edition, Red Flag Midinux, and Pepper Linux.."

 Tizen was MeeGo who was Moblin or Mobile Linux
MeeGo was designed to act as an operating system for hardware platforms such as netbooks, entry-level desktops, nettops, tablet computers, mobile computing and communications devices, in-vehicle infotainment devices, SmartTV / ConnectedTV, IPTV-boxes, smart phones, and other embedded systems.

Smartwatchs started with Android, now they have a Tizen version, this watch may be a good experimental hardware for Embedded Systems hackers to test out their own custom linux firmware !

If you haven't heard, in 2010 Moblin became MeeGo! MeeGo is an open source, Linux project which
brings together the Moblin project a single open source activity.

By now, you may have read that The Linux Foundation, with the support of several other companies, announced a new project, Tizen, to build a new operating system for devices. This new project is first and foremost open source, and based on Linux. So it begs the question: why not just evolve MeeGo? We believe the future belongs to HTML5-based applications,

Tizen - An open source, standards-based software platform for multiple device categories.

For Smartphones, Tablets, Netbooks and Smart TV. Also one for your Car, Boat or Chopper for an In-Vehicle Infotainment Gadget.

PICMG - Open specifications for Modular Computing

PICMG is a consortium of companies who collaboratively develop open specifications for high performance telecommunications and industrial computing applications.

PICMG - Open specifications for Modular Computing

Founded in 1994, PICMG’s original mission was to extend the PCI standard to non-desktop applications. The formal name of the organization is the PCI Industrial Computer Manufacturers Group. It is now known as PICMG (pronounced “PICK-EM-GEE” or “PICK-MIG”).

Specs and Standards for Advanced Mezzanine Card, AdvancedTCA, COM Express, CompactPCI, e-PCI-X, MicroTCA and others.

PICMG - Open specifications for Modular Computing

PICMG 3.7 AdvancedTCA

To better address the datacenter market PICMIG has developed thePICMG 3.7 AdvancedTCA specification, as an extension to the existing ATCA standard. The extension utilizes the available depth in server cabinets and the environmental characteristics of datacenters to dramatically increase the power and throughput, while reducing the cost of the systems.

PCI-ISA - Passive Backplanes - "The PCI-ISA passive backplane standard moves all of the components normally located on the motherboard to a single plug-in card. Looking much like a standard ISA or PCI card, a PCI-ISA CPU card has two edge connectors on it - one for the PCI bus and one for the ISA bus. The "motherboard" is replaced with a simple "passive backplane" that has only connectors soldered to it."

The Qseven concept is an off-the-shelf, multi vendor, Computer-On-Module that integrates all the core components of a common PC and is mounted onto an application specific carrier board. Qseven modules have a standardized form factor of 70mm x 70mm and have specified pinouts based on the high speed MXM system connector that has a standardized pinout regardless of the vendor.

Qseven - Computer-On-Module Standard

These functions include, but are not limited to, graphics, sound, mass storage, network and multiple USB ports. A single ruggedized MXM connector provides the carrier board interface to carry all the I/O signals to and from the Qseven module. This MXM connector is a well known and proven high speed signal interface connector that is commonly used for high speed PCI Express graphics cards in notebooks.

Qseven - Computer-On-Module Standard

Qseven offers the newest I/O technologies on this minimum size form factor. Some are .. PCIexpress, USB 2. Serial ATA, Secure Digital I/O interface. Gigabit Ethernet
    QBliss Qseven

    Since the Qseven form factor was introduced; many manufacturers of boards and software have adopted it. The combination of Qseven and RISC gains more and more importance. The reason is the compatibility of the offered boards, as well as the small form factor (70x70mm) with an inexpensive plug connector

    PC User Interface and Wireless Power

    Wireless Charging is a Reality today, it was first conceived by me in the 90s. The first page published related to that in my netscape site.

    This was conceived to get rid of cables for data and power on my desktop. I felt if we use Optics for Data and Wireless Ferrite Contact Plates to transfer power, there would be no wires at all on the desk. I even experimented with RS232 Serial Port and Ferrite Slices below thin Acrylic Plastic Sheet, it worked.

    I did not patent any of my concepts, but it is offered to all humanity as an Open Design, like all my other work.

    Here is a planar transformer which has PCB tracks for winding. This show that there is more scope of innovation in such ferrite transformers for short range wireless power.

    PC User Interface and Wireless Power

    Objects kept on a electromagnetic table must be able to draw energy from that. A Notebook or tablet can be just placed on this table to get charged.

    The optic ball-less mouse is a great step in mice-tech user-interface. This mouse consumes more power, for a wireless mouse a capacitive sensor matrix based sensing may be better.

    Touch Screen on PC is not common place. A combination of Touch screen and Mouse is excellent for all age-groups. Large monitors can have at least two inches of touch screen area at bottom.

    Laptops, LCD Monitors make UPS (Uninterrupted Power Supply) last longer and it reduces electricity costs.

     Wireless Power for Wireless Peripherals

    Wireless Mouse with capacitive sensors may consume less power, no batteries works on a Supercap, Connector-less ferrite dock for recharging

    Wireless mouse rechargeable battery can recharge while moving on the Mouse Pad made of Ferrite/Ceramic 1′ Sq with Power Hot Spots every 3″

    Flexible Ferrite, Silicone & Ferrite based Solid emulsion. Can be made as computer table mats to charge the supercaps of peripherals.

    The Energy Efficient Wireless Peripherals can just be placed on this mat to draw the power without wires. Wireless power and Wireless Data.

    Usability and Ergonomics Review
    Aggregated Notes from 2008-12

    Usability and Ergonomics of Electronic Consumer Equipment, product risks and safety are best studied with very old and very young people.

    Personal Computers, Netbooks, Portable Communicating Devices, Remote Controls are where Usability Issues abound, and can be studied/remedied.

    Optical Rotary Encoders, Magnetic/Eddy/Capacitive/Hall Effect based Non-Contact Joysticks, Makes Human An analog Interface with Digital Output.

    For the people who type with two fingers; A Circular Keyboard is right. A Capacitive Touch Gesture Pad can replace the Mouse. Health & Ergo.
