Digital Jewellery

 ABSTRACT
The latest computer craze has been to be able to wear wireless computers. The Computer Fashion Wave, "Digital Jewelry" looks to be the next sizzling fashion trend of the technological wave. The combination of shrinking computer devices and increasing computer power has allowed several companies to begin producing fashion jewelry with embedded intelligence. Today’s, manufacturers place millions of transistors on a microchip, which can be used to make small devices that store tons of digital data.. The whole concept behind this is to be able to communicate to others by means of wireless appliances. The other key factor of this concept market is to stay fashionable at the same time.Digital jewellry is the fashion jewelry with embedded intelligence. “Digital jewellery” can help you solve problems like forgotten passwords and security badges. “Digital jewelry” is a nascent catchphrase for wearable ID devices that contain personal information like passwords, identification, and account information. They have the potential to be all-in-one replacements for your driver's license, key chain, business cards, credit cards, health insurance card, corporate security badge, and loose cash. They can also solve a common dilemma of today's wired world – the forgotten password.By the end of the decade, we could be wearing our computers instead of sitting in front of them.

Digital jewellery Components
Each piece of jewelry contains a part of cell phone embedded in them,together works as a normal cellular phone.The various components that are inside cell phone such as Microphone,Receiver,display,touch pad,circuit board,antenna are embedded into different jewelry parts according to their working.IBM has developed a prototypes of cell phone that that consists of several pieces of digital jewelry that will work together wireless.

Here are the pieces of computerized-jewellery phone and their functions:
•Earrings - Speakers embedded into these earrings will be the phone's receiver.
•Necklace - Users will talk into the necklace's embedded microphone.
•Ring - Perhaps the most interesting piece of the phone, this "magic decoder ring” is equipped with light-emitting diodes (LEDs) that flash to indicate an incoming call. It can also be programmed to flash different colors to identify a particular caller or indicate the importance of a call.
•Bracelet -Equipped with a video graphics array (VGA) display, this wrist display could also be used as a caller identifier that flashes the name and phone number of the caller.
With a jewellery phone, the keypad and dialing function could be integrated into the bracelet, or else dumped altogether -- it's likely that voice-recognition software will be used to make calls, a capability that is already commonplace in many of today's cell phones. Simply say the name of the person you want to call and the phone will dial that person. IBM is also working on a miniature rechargeable battery to power these components.

The same ring that flashes for phone calls could also inform you that e-mail is piling up in your inbox. This flashing alert could also indicate the urgency of the e-mail.The mouse-ring that IBM is developing will use the company's Track Point technology to wirelessly move the cursor on a computer-monitor display. (Track Point is the little button embedded in the keyboard of some laptops).

In the coming age no longer you will find the displays on wall or desktops.You can simply view the images or content through your sunglasses or Bracelet.this the main and important advantage of Digital jewelry.Researchers are overcoming several obstacles facing these new wearable displays, the most important of which is the readability of information displayed on these tiny devices.



Prototype bracelet display developed by IBM
Charmed Technology is already marketing its digital jewelry, including a futuristic-looking eyepiece display. The eyepiece is the display component of the company's Charmed Communicator, a wearable, wireless, broadband-Internet device that can be controlled by voice, pen or handheld keypad. The Communicator can be used as an MP3 player, video player and cell phone. The Communicator runs on the company's Linux-based Nanix operating system. 

Technical specifications of Digital Jewelry
Digital jewellery devices consist of a screen or display for information, most likely consisting of 7-16-segment, or dot matrix LEDs, LCDs, or other technologies such as electroluminescent material (EL) or others, which could become an optional display. So too, an audiovisual or other 'display' could consist of a speaker, a single flashing light, a sensor of some kind (such as a temperature driven EL display), or other informational aesthetic. The display layer sits on a face of the device, which is enclosed in some material such as plastic, metal, crystal, or other material. It has external switches and buttons on its side and a data-port for accessing the programmable electronic circuit inside. A micro controller that is a surface mounted device (SMD) on a printed circuit board (PCB) with resistors (R) and capacitors (C) are the internal 'guts' of the jewelry.

Digital Jewellery can be made in many different sizes and shapes with a variety of materials ranging from plastic and metal to rubber and glass. They utilize electromagnetic properties and electronics to display information through a screen or display of some kind. This could range from LED 7-segment, 16-segment, dot matrix, and other programmable LEDs devices to LCDs, OLEDs, and other display devices.


Electro Magnetic Beads
The closest comparison to this model is that of 'beads' which are strung together to make a custom necklace or bracelet, with interchangeable electromagnetic component systems or devices. One bead may be a capacitor on the inside, and a solar panel on the outside. Another bead may have an internal resistor which feed power into a programmed micro controller bead which drives an external screen, with other options available in a variety of bead configurations which compose a circuit, including beads with a piezo element, voltage regulator, crystal, or rechargeable battery as part of the modular jewel circuit. The number of data pins on the micro controller needs to be enough to easily program the display layer plus the switches without overly complex and advanced coding methods.


Java Ring

It seems that everything we access today is under lock and key. Even the devices we use are protected
by passwords. It can be frustrating trying to keep with all of the passwords and keys needed to access
any door or computer program. Dallas Semiconductor is developing a new Java-based, computerized
ring that will automatically unlock doors and log on to computers.The Java Ring can be programmed to give you access to every door and device.

The Java Ring is snapped into a reader,called a Blue Dot receptor, to allow communication between a host system and the Java Ring.

 Blue Dot receptor

The Java Ring is a stainless-steel ring, 16-millimeters (0.6 inches) in diameter, which houses a 1-
million-transistor processor, called an iButton. The ring has 134 KB of RAM, 32 KB of ROM, a real-
time clock and a Java virtual machine, which is a piece of software that recognizes the Java language and translates it for the user's computer system. Digital jewelry, (designed to supplement the personal computer,) will be the evolution in digital technology that makes computer elements entirely compatible with the human form.

Highlights of Java Ring
• Runs Java better (plus portions enhance Java Card 2.0)
• Careful attention to physical security (rapid zeroization)
• Durability to stand up to everyday use
• High memory capacity (up to 134K bytes NV SRAM)
• Retail connectivity to 250 million existing computers (less if designed- in before manufacturing)
