INSIGHT APPLE PA TENT UPDA TE WORDS AND IMAGES PROVIDED BY P TTENTL APPLE.COM A Y The Secrets behind the new iPad Air Retina Display Revealed Apple Advances their Device Free Fall Protection Invention New Coating Added to the iPad Air Retina Display In March of this year Apple first introduced a new invention covering a future free fall protection systemin great detail. Apple's proposed protective mechanism is configured to selectively alter a center of mass of the electronic device so that it doesn't fall on its glass face. Today's patent application illustrates one of Apple's latest advances in this project that utilizes a sophisticated magnets system used as a form of a guidance system to ensure that the fall protects the device. Two new technologies that went into the iPad Air's new improved Retina display were revealed today. The first of Apple's new iPad Air display technologies involves the application of a new coating technology. The previous iPad display was coated with indium tin oxide (ITO) to form an LCD insulator film. However, this time around, the thickness of this film was reduced and transmission factor enhanced with application of ITO and multi-layer coating technology.  Apple Continues to Work on a Free Fall Protection System Haptic devices are generally designed to provide a tactile feedback to users of electronic devices. A commonly implemented haptic device is an eccentric weight that is rotated to cause vibration to occur. Generally, the stronger the vibrations are, the more effective the haptic device. A stock market analyst covering this technology stated that "In general, several layers of coating increase display thickness. However, the multi-layer coating technology applied to iPad's LCD decreases thickness on the contrary and enhances transmission factor. There are only a handful of companies in the world that have the multilayer coating technology." The amplitude may vary with several parameters; some of these are the frequency at which the weight rotates and the location of the center of mass relative to the axis of rotation, both of which are generally fixed parameters in conventional haptic devices. The thin glass technology has also been further advanced. This is a technology to melt upper and lower substrates of a display glass panel using chemicals to make them thinner. Apple's invention relates to advancing a haptics device to perform a function beyond mere vibration. Apple's invention relates to systems and techniques for operating a The iPad Air Created with New Thinning Glass Process The second improvement made to the iPad Air's Retina display involves a new glass thinning process technique that has recently been perfected. In the past, about half the 1mm thickness of upper and lower glass substrates was reduced using thin glass technology. The new iPad, reportedly, is created with LCD glass ground off by 60 – 70%. To achieve the new Retina display's improvements, Apple turned to Korean manufacturers such as GD, Avatec, UID and Chemtronics. 28 MacDirectory dynamic rotating mass. Apple states that the dynamic rotating mass may be used to generate vibration and/or alter angular momentum of a falling device. In particular, a system is provided having a motor, a shaft extending from the motor, and a weight attached to the shaft. Operation of the motor rotates the shaft and the weight is dynamically reconfigurable when rotating to change the location of the center of mass relative to an axis of rotation.
