Digital Photography Jewelry PDF

Digital jewelry is the fashion jewelry with embedded intelligence. “Digital jewelry” 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.

DIGITAL JEWELRY AND ITS COMPONENTS:

Soon, cell phones will take a totally new form, appearing to have no form at all. Instead of one single device, cell phones will be broken up into their basic components and packaged as various pieces of digital jewelry. Each piece of jewelry will contain a fraction of the components found in a conventional mobile phone. Together, the digital-jewelry cell phone should work just like a conventional cell phone.

The various components that are inside a cell phone :

Microphone, Receiver, Touch pad, Display, Circuit board, Antenna, and Battery .

IBM has developed a prototype of a cell phone that consists of several pieces of digital jewelry that will work together wirelessly, possibly with Blue tooth wireless technology, to perform the functions of the above components.

Cell phones may one day be comprised of digital accessories that

Work together through wireless connections.

Here are the pieces of computerized-jewelry 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 jewelry 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 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). IBM Researchers have transferred TrackPoint technology to a ring, which looks something like a black-pearl ring. On top of the ring is a little black ball that users will swivel to move the cursor, in the same way that the TrackPoint button on a laptop is used. This Track Point ring will be very valuable when monitors shrink to the size of watch face. In the coming age of ubiquitous computing, displays will no longer be tied to desktops or wall screens. Instead, you'll wear the display like a pair of sunglasses or a bracelet. 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.

TECHNICAL SPECIFICATIONS OF DIGITAL JEWELRY:

Digital jewelry 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.

Sensitive Skin PPT : Seminar Report|PPT|PDF|DOC|Presentation|Free Download

Sensitive skin is a large-area, flexible array of sensors with data processing capabilities, which can be used to cover the entire surface of a machine or even a part of a human body. Depending on the skin electronics, it endows its carrier with an ability to sense its surroundings via the skin's proximity, touch, pressure, temperature, chemical/biological, or other sensors. Sensitive skin devices will make possible the use of unsupervised machines operating in unstructured, unpredictable surroundings among people, among many obstacles, outdoors on a crowded street, undersea, or on faraway planets. Sensitive skin will make machines “cautious” and thus friendly to their environment. This will allow us to build machine helpers for the disabled and elderly, bring sensing to human prosthetics, and widen the scale of machines' use in service industry. With their ability to produce and process massive data flow, sensitive skin devices will make yet another advance in the information revolution. This paper surveys the state of the art and research issues that need to be resolved in order to make sensitive skin a reality.

Skin Materials

- Sensitive Skin material will hold embedded sensors and related signal processing hardware. It needs to be flexible enough for attaching it to the outer surfaces of machines with moving parts and flexible joints. - The skin must stretch, shrink, and wrinkle the way human skin does, or to have other compensating features. Otherwise, some machine parts may become "exposed" due to the machine's moving parts, and have no associated sensing.

- Wiring must keep its integrity when Sensitive Skin is stretched or wrinkled. This requirement calls for novel wire materials, e.g. conductive elastomers or vessels carrying conductive liquid, or novel ways of wire design with traditional materials, such as helical, stretchable wires

From the device point one might wish a Sensitive Skin to have some of the following capabilities:

• Flexible or deformable, Can be tiled or cut, This aspect ties in to cost and repair ability, High detectivity, On-skin switching and signal processing, Fault tolerances by distributing functions/computing, or protect processor units. Transmission by wire or optical fiber, or wireless: RF, UHF, free-space optical.

• Power by wire photovoltaics, RF, fuel cells, micro engines, or from energy harvesting - (skin-integrated mechanical power generators). Power storage in batteries. Or as fuel for fuel cells and micro engines.

• Sensitive Skin sensor components will be deployed in two dimensional arrays of sufficiently high density

• Smaller arrays may be of use as well: the key feature is that the skin should allow, by itself or with appropriate data processing, to identify with reasonable accuracy the points of the machine's body where the corresponding sensor readings take place.

• “Self-sensing” ability of the skin is highly desirable; this may include sensing of contamination, dust, chemical substances, temperature, radiation, as well as detection of failure of individual or multiple skin sensors and the ability to work around failed areas.

• The ability to measure distance to objects would be a great advantage for enabling dexterous motion of the machine that carries the skin

Manufacturing Of Large-Area Sensitive Skin

The materials needed for the printing of sensor circuits include metallic conductors, insulators, semiconductors for transistors and light emitters, piezoelectric materials, etc. This approach to the printing of active circuits explores the territory that lies between IC's and printed-wire boards. In effect, sensitive skin devices will contain active circuits monolithically integrated with their packaging. Completed thin-film circuits are at most a few micrometers thick. Therefore, the substrate and encapsulation constitute the bulk of the finished product. Reduction of their weight and thickness becomes important.

When the substrate is reduced to a thickness where it becomes flexible, it also becomes usable in continuous, roll-to-roll paper-like production. The finished circuit then is a flexible foil, and using equally thin encapsulation will preserve this flexibility. Rugged thin-film circuits are a natural consequence of the mechanics of thin foil substrates. In devising printing techniques for fabricating sensitive skin, the questions of feature size and of overlay registration must be answered. The development of microelectronics has shown that the search for high pattern density is one of the main drivers of IC technology. Therefore, it is instructive to estimate the density of active devices that could be produced by using conventional printing techniques.

The physical limits of several printing techniques are considerably finer than the resolution and registration of conventional printing equipment. Laser writing can produce a resolution of the order of 1 micro meter. Nanoimprinting has demonstrated a resolution in the tens of nanometer range. The density of directly printed devices can be raised orders of magnitude above ~ 10000 per square centimeter.

5 Pen PC Technology PPT Free Download

P-ISM (“Pen-style Personal Networking Gadget Package”), which is nothing but the new discovery, which is under developing, stage by NEC Corporation. 5 Pen PC Technology is a gadget package including five functions: a pen-style cellular phone with a handwriting data input function, virtual keyboard, a very small projector, camera scanner, and personal ID key with cashless pass function. 5 Pen PC Technology are connected with one another through short-range wireless technology. The whole set is also connected to the Internet through the cellular phone function. This personal gadget in a minimalist pen style enables the ultimate ubiquitous computing.

In fact, no-one expects much activity on 802.11n installations until the middle of 2008. “Rolling out 802.11n would mean a big upgrade for customers who already have full Wi-Fi coverage, and would be a complex add-on to existing wired networks, for those who haven't. Bluetooth is widely used because we can able to transfer data or make connections without wires. 5 Pen PC Technology is very effective because we can able to connect whenever we need without having wires. 5 Pen PC Technology are used at the frequency band of 2.4 GHz ISM (although they use different access mechanisms). Blue tooth mechanism is used for exchanging signal status information between two devices. 5 Pen PC Technology techniques have been developed that do not require communication between the two devices (such as Blue tooth's Adaptive Frequency Hopping), the most efficient and comprehensive solution for the most serious problems can be accomplished by silicon vendors. They can implement information exchange capabilities within the designs of the Blue tooth. The circuit diagram for the 802.11B/G is given below. It is nothing but also type of Blue tooth. Using this connectivity we can also connect it with the internet and can access it anywhere in the world.

LED Projector

The role of monitor is taken by LED Projector which projects on the screen. The size of the projector is of A4 size. It has the approximate resolution capacity of 1024 X 768. Thus it is gives more clarity and good picture.

Virtual Keyboard

The Virtual Laser Keyboard (VKB) is the ULTIMATE new gadget for PC users. The VKB emits laser on to the desk where it looks like the keyboard having QWERTY arrangement of keys i.e., it uses a laser beam to generate a full-size perfectly operating laser keyboard that smoothly connects to of PC and Most of the handheld devices (PDA's, tablet PC's). The I-Tech laser keyboard acts exactly like any other "ordinary" keyboard.

Features Of Virtual Keyboards Are

1. VKB settings can be changed by Sound:

2. Controllable Virtual Keyboard sound effects (key clicks)

3. Connection: Connection to the appropriate Laptop/PC port

4. Intensity: Intensity of the projected Virtual Keyboard

5. Timeouts: coordinated timeouts to conserve the Virtual Keyboard's battery life

6. Sensitivity: adjustable sensitivity of the Virtual Keyboard

7. Auto-repeat: Allows the VKB to automatically repeat a key based on prescribed parameters.

Battery

The most important part in the portable type of computer is its battery. Usually batteries must be small in size and work for longer time. It comes with a battery life of 6+. For normal use it can be used for 2 weeks.This 'pen sort of instrument' produces both the monitor as well as the keyboard on any flat surfaces from where you can carry out functions you would normally do on your desktop computer.
