Facebook Privacy

Many people believe that the app is especially invasive or tending to intrude on a persons thoughts or privacy.

A myth of Facebook messenger is that the app’s term of service are different from Facebook’s own official terms. When in reality Facebook terms of service is the same in all of its apps including the messenger app. People who use messenger on an Android say it is upsetting is the list of permissions. On the list there is 10 items that states the access to the features on your phone. App on your phone like contacts, calendar, location data and Wi-Fi information.

Myth: Facebook will direct the app to send SMS, or text, messages without your permission. When in reality one of the permissions does say that Facebook can edit, receive, read and send SMS message.

The app ask for the ability to “call phone numbers without your intervention,” and “use the camera at any time without your permission.” What this means is that the app can send or call your family or friends to make them buy something. Also, they can use your camera to tell where you are and use that information and sell it off.

But, according to Facebook, the concerns about its messenger app has been overblown, and based on misinformation. Much of the problem, Facebook says, is due to Android’s rigid policy on permissions. Facebook says it doesn’t et to write its own, and instead must use generic language provided by Android.

Android users must agree to all permissions at once, before using the app, for every feature an app might use. On iPhones, users agree to the permissions when they come up during the normal use of the app. For instance, if an iPhone user never makes a voice call with Facebook Messenger, the app might never ask for permission to use the phone’s microphone.

3D Printing

What is 3D printing?

            3D printing or additive manufacturing is a process of making three-dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the entire object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.

How does 3D printing work?

It all starts with making a virtual design of the object you want to create. This virtual design is made in a CAD (Computer Aided Design) file using a 3D modeling program (for the creation of a totally new object) or with the use of a 3D scanner (to copy an existing object). This scanner makes a 3D digital copy of an object and puts it into a 3D modeling program.

To prepare the digital file created in a 3D modeling program for printing, the software slices the final model into hundreds or thousands of horizontal layers. When this prepared file is uploaded in the 3D printer, the printer creates the object layer by layer. The 3D printer reads every slice (or 2D image) and proceeds to create the object blending each layer together with no sign of the layering visible, resulting in one three dimensional object.

Methods and Technology

            Not all 3D printers use the same technology to realize their objects. There are several ways to do it and all those available as of 2012 were additive, differing mainly in the way layers are build to create the final object. Some methods use melting or softening material to produce the layers. Selective laser sintering (SLS) and fused deposition modeling (FDM) is the most common technologies using this way of printing. Another method of printing is to lay liquid materials that are cured with different technologies. The most common technology using this method is called stereo lithography (SLA). What sterolithography is the technology to lay liquid minerals is a three-dimensional pattern.

The History

In the history of manufacturing, subtractive methods have often come first. The province of machining (generating exact shapes with high precision) was generally a subtractive affair, from filing and turning through milling and grinding.

Additive manufacturing’s earliest applications have been on the toolroom end of the manufacturing spectrum. For example, rapid prototyping was one of the earliest additive variants and its mission was to reduce the lead time and cost of developing prototypes of new parts and devices, which was earlier only done with subtractive toolroom methods (typically slowly and expensively). However, as the years go by and technology continually advances, additive methods are moving ever further into the production end of manufacturing. Parts that formerly were the sole province of subtractive methods can now in some cases be made more profitably via additive ones.
However, the real integration of the newer additive technologies into commercial production is essentially a matter of complementing subtractive methods rather than displacing them entirely. Predictions for the future of commercial manufacturing, starting from today’s already- begun infancy period, are that manufacturing firms will need to be flexible, ever-improving users of all available technologies in order to remain competitive. So in conclusion 3D printing will help with the medical field. It will also advance us in many other work fields.

Wireless Charging

Inductive charging (also known as "wireless charging") uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.

         What that means is that when you charge your device it uses an electromagnetic field. So the energy is sent from the primary coil to the phone. Therefore, making it fully charged when you take it off.

         Induction chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery. The two induction coils in proximity combine to form an electrical transformer.

          What this means is that the charger uses induction coil. That makes the electromagnetic field.

         Greater distances between sender and receiver coils can be achieved when the inductive charging system uses resonant inductive coupling. Recent improvements to this resonant system include using a movable transmission coil i.e. mounted on an elevating platform or arm, and the use of advanced materials for the receiver coil made of sliver plated copper or sometimes aluminum to minimize weight and decrease resistance due to the skin effect.

         What this means is that the charger is portable. So when you move the charger it will be charging still.

Whatever the application, the removal of the physical connection delivers a number of benefits over traditional cable connectors, some of which aren’t always obvious.  The video below highlights just some of the benefits and advantages of wireless charging and offers an insight into a world where wireless power is widely integrated into the home, office and our everyday lives.

Benefits of wireless chargers

•   Greater convenience and ubiquity for charging of everyday devices

•   Reduce cost associated with maintaining mechanical connectors

•   Safe powering or charging devices that need to remain sterile or hermetically sealed (waterproof)

•   Prevent corrosion due to elements such as oxygen and water

•   Eliminate sparks and debris associated with wired contacts

Current options for wireless charging of smartphones and tablets involve the use of a charging pad, which acts as the transmitter, transferring power to a miniaturized wireless receiver integrated into the smartphone or tablet.

The Proxi 2D Charging Solution is the safest and most efficient wireless charging pad technology for smartphones, phablets and tablets, delivering simultaneous wireless charging of multiple devices, with full spatial freedom for the placement of devices in any position (no exact alignment).

Miniaturized receivers are integrated directly into the device, removing the need for external housing covers or sleeves on devices.  Follow the link to read more about our Proxi 2D Pad charging technology. With continued advances in wireless charging technology, transmitters built into workstations, desks, tables and a whole range of everyday furniture will soon become a reality. So in conclusion the wireless charger is portable and efficient.

Suspended Animation

Suspended Animation is when the surgeons drain out your blood then replace it ice-cold saline solution. When they put in the solution and cools the body’s core to about 50 to 55 degrees. 

   At normal body temperatures, cells need regular oxygen supply. When the heart stops, blood no longer carries oxygen throughout the body, and the brain can only survive for a few minuets. 

         At these reduced temperatures, however, tissue cells need less oxygen because all chemical reactions slow down. It’s the same principal that has allowed some people to survive near-drownings in cold water, despite being submerged for half-hour or more.

         The included hypothermia, or “suspended animation,” process is expected to buy doctors enough time— at least 45 minutes— to get patients into the operating room, hook them up to the machines to restart their circulation, warm them up and then restore their blood.                   The groundbreaking process has proven successful in animal trials involving pigs. Now Tisherman and his researchers plan to carry out a similar trial with humans, operating 10 patients who get EPR with 10 who don’t. The patients will have suffered cardiac arrest after a traumatic injury and have little chance of survival under normal circumstances.                      The federal government is watching with interest. Tisherman said the Food and Drug Administration is overseeing the trial, and the Department of Defense, which sees potential for treating soldiers in the field, has contributed funding.                                                                                       It will take several years to complete the trial and crunch the data. Tisherman's hope is to eventually prove the process works and help it spread to other trauma centers around the world.                                             "As trauma surgeons, we're always fighting against the clock. And we've all seen people who had injuries we could fix if we just had a few more minutes. It's heartbreaking when these patients don't make it," he told CNN."We find it exciting that this might give us a way to save people that we otherwise can't."
