Google class

Camera:

Google Glass has the ability to take photos and record 720p HD video. While video is recording, the screen stays on.

Touch pad:

A man controls Google Glass using the touch pad built into the side of the device.A touch-pad is located on the side of Google Glass, allowing users to control the device by swiping through a timeline-like interface displayed on the screen.[51] Sliding backward shows current events, such as weather, and sliding forward shows past events, such as phone calls, photos, circle updates, etc.

Applications:

Google Glass applications are free applications built by third-party developers. Glass also uses many existing Google applications, such as Google Now, Google Maps, Google+, and G mail.

Third-party applications announced at South by Southwest include Ever note, Kitsch, The New York Times, and Path.

Google released the Mirror API, allowing developers to start making apps for Glass. In the terms of service, it is stated that developers may not put ads in their apps or charge fees; a Google representative told The Verge that this might change in the future.Many developers and companies have built applications for Glass, including news apps, facial recognition, exercise, photo manipulation, translation, and sharing to social networks, such as Facebook and Twitter.

My Glass:

Google offers a companion Android and iOS app called My Glass, which allows you to configure and manage your device.

Voice activation

Other than the touchpad, Google Glass can be controlled using "voice actions". To activate Glass, wearers tilt their heads 30° upward (which can be altered for preference) or tap the touchpad, and say "O.K., Glass." Once Glass is activated, wearers can say an action, such as "Take a picture", "Record a video", "Hangout with [person/Google+ circle]", "Google 'What year was Wikipedia founded?'", "Give me directions to the Eiffel Tower", and "Send a message to John"(many of these commands can be seen in a product video released in February 2013).For search results that are read back to the user, the voice response is relayed using jawbone conduction through a transducer that sits beside the ear, thereby rendering the sound almost inaudible to other people

The quality of pictures and video are usable for healthcare education, reference, and remote consultation. The camera needs to be tilted to different angle for most of the operative procedures

Tel-consultation is possible—depending on the available bandwidth—during operative procedures.

A stabilizer should be added to the video function to prevent choppy transmission when a surgeon looks to screens or colleagues.

Battery life can be easily extended with the use of an external battery. Controlling the device and/or programs from another device is needed for some features because of sterile environment.

Text-to-speech ("Take a Note" to Ever-note) exhibited a correction rate of 60 percent, without the addition of a medical thesaurus.

A protocol or checklist displayed on the screen of Glass can be helpful during proceduresPrivacy concerns Steve Mann, inventor of Eye Tap, wearing several developments of his device which has been compared with Google Glass.

The eye wear's functionality and minimalist appearance have been compared to Steve Man's Eye Tap, also known as "Glass" or "Digital Eye Glass", although Google Glass is a "Generation-1 Glass" compared to Eye Tap, which is a "Generation-4 Glass". According to Mann, both devices affect both privacy and secrecy by introducing a two-sided surveillance and surveillance.

Concerns have been raised by various sources regarding the intrusion of privacy, and the etiquette and ethics of using the device in public and recording people without their permission, even though many artists practicing street photography or life reportage, including Henri Cartier-Bronson, have made history[peacock term] taking pictures of people in public without their consent or knowledge[citation needed], and today there are web services such as Google Street View doing the same on a massive scale[citation needed]. There is controversy that Google Glass would violate privacy rights due to security problems and others.

3D Printer Machine

3D Printer:

3D printing or Additive manufacturing is a process of making a two-dimensional solid object of virtually any shape from a digital classical. 3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes. 3D printing is also considered distinct from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling.

3D Printable Method:

3D printable models may be created with a computer aided design package or via 3D scanner. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of analyzing and collecting data of real object; its shape and appearance and builds digital, three dimensional models.

Both manual and automatic creation of 3D printable models is difficult for average consumers. This is why several 3D printing marketplaces have emerged over the last years. Among the most popular are Shape ways, Shivering and Threading.

Printing:

To perform a print, the machine reads the design from an STD file and lays down successive layers of liquid, powder, paper or sheet material to build the model from a series of cross sections. These layers, which correspond to the virtual cross sections from the CAD model, are joined or automatically fused to create the final shape. The primary advantage of this technique is its ability to create almost any shape or geometric feature.

Printer resolution describes layer thickness and X-Y resolution in dpi (dots per inch),[citation needed] or micrometers. Typical layer thickness is around 100 µm (250 DPI), although some machines such as the Object Conner series and 3D Systems' Project series can print layers as thin as 16 µm (1,600 DPI).[19] X-Y resolution is comparable to that of laser printers. The particles (3D dots) are around 50 to 100 µm (510 to 250 DPI) in diameter.

 Granular materials binding

The Candy Fab granular printing system uses heated air and granulated sugar to produce food-grade art objects.

Another 3D printing approach is the selective fusing of materials in a granular bed. The technique fuses parts of the layer, and then moves the working area downwards, adding another layer of granules and repeating the process until the piece has built up. This process uses the unused media to support overhangs and thin walls in the part being produced, which reduces the need for temporary auxiliary supports for the piece. A laser is typically used to sinner the media into a solid. Examples include selective laser wintering (S LS), with both metals and polymers (e.g. PA, PA-GS, Rigid GF, PEEK, PS, Aluminum, Carbonize, Elastoplast), and direct metal laser wintering.

Selective Laser Wintering (SLS) was developed and patented by Dr. Carl Rickard and Dr. Joseph Beam an at the University of Texas at Austin in the mid-1980s, under sponsorship of DARA.[27] A similar process was patented without being commercialized by R. F. Householder in 1979.

Selective Laser Melting (SLM) does not use wintering for the fusion of powder granules but will completely melt the powder using a high-energy laser to create fully dense materials in a layer wise method with similar mechanical properties to conventional manufactured metals.
