BION System for Distributed Neural
Medical Engineering & Physics 23 (2001) 9–18 www.elsevier.com/locate/medengphy BION system for distributed neural prosthetic interfaces Gerald E. Loeb *, Raymond A. Peck, William H. Moore, Kevin Hood A.E. Mann Institute for Biomedical Engineering, University of Southern California, 1042 West 36th Place, Room B-12, Los Angeles, CA 90089-1112, USA Received 5 October 2000; received in revised form 18 January 2001; accepted 26 January 2001 Abstract We have developed the first in a planned series of neural prosthetic interfaces that allow multichannel systems to be assembled from single-channel micromodules called BIONs (BIOnic Neurons). Multiple BION implants can be injected directly into the sites requiring stimulating or sensing channels, where they receive power and digital commands by inductive coupling to an externally generated radio-frequency magnetic field. This article describes some of the novel technology required to achieve the required microminiaturization, hermeticity, power efficiency and clinical performance. The BION1 implants are now being used to electrically exercise paralyzed and weak muscles to prevent or reverse disuse atrophy. This modular, wireless approach to interfacing with the peripheral nervous system should facilitate the development of progressively more complex systems required to address a growing range of clinical applications, leading ultimately to synthesizing complete voluntary functions such as reach and grasp. 2001 IPEM.

Energy Efficient Wifi Tethering on a Smartphone
Energy Efficient Wifi Tethering on a Smartphone Kyoung-Hak Jung†, Yuepeng Qi†, Chansu Yu†‡, and Young-Joo Suh† †Department of Computer Science and Engineering & Division of IT Convergence Engineering Pohang Univ. of Science and Tech., Pohang, 790-784, Republic of Korea Email: {yeopki81, yuepengqi, yjsuh}@postech.ac.kr ‡Department of Electrical and Computer Engineering Cleveland State University, Cleveland, Ohio 44115 Email: [email protected] Abstract—While numerous efforts have been made to save energy of “client” devices but it has not been addressed for access points (APs) as they are assumed to be supported by AC power. This paper proposes E-MAP, which is an energy saving algorithm for a tethering smartphone that plays a role of mobile AP (MAP) temporarily. It saves MAP’s energy by introducing the sleep cycle as in power save mode (PSM) in 802.11 but successfully keeps clients from transmitting while it sleeps.

The first publicly available smartphone running Android, the HTC Dream, was released on October 22, 2008. The user interface of Android is based on direct manipulation, using touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching and reverse pinching to manipulate on-screen objects. Internal hardware such as accelerometers, gyroscopes and proximity sensors are used by some applications to respond to additional user actions, for example adjusting the screen from portrait to landscape depending on how the device is oriented. -
History and Evolution of the Android OS
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Springer - Publisher Connector CHAPTER 1 History and Evolution of the Android OS I’m going to destroy Android, because it’s a stolen product. I’m willing to go thermonuclear war on this. —Steve Jobs, Apple Inc. Android, Inc. started with a clear mission by its creators. According to Andy Rubin, one of Android’s founders, Android Inc. was to develop “smarter mobile devices that are more aware of its owner’s location and preferences.” Rubin further stated, “If people are smart, that information starts getting aggregated into consumer products.” The year was 2003 and the location was Palo Alto, California. This was the year Android was born. While Android, Inc. started operations secretly, today the entire world knows about Android. It is no secret that Android is an operating system (OS) for modern day smartphones, tablets, and soon-to-be laptops, but what exactly does that mean? What did Android used to look like? How has it gotten where it is today? All of these questions and more will be answered in this brief chapter. Origins Android first appeared on the technology radar in 2005 when Google, the multibillion- dollar technology company, purchased Android, Inc. At the time, not much was known about Android and what Google intended on doing with it. Information was sparse until 2007, when Google announced the world’s first truly open platform for mobile devices. The First Distribution of Android On November 5, 2007, a press release from the Open Handset Alliance set the stage for the future of the Android platform. -

Essential Phone on Its Way to Early Adopters 24 August 2017, by Seung Lee, the Mercury News
Essential Phone on its way to early adopters 24 August 2017, by Seung Lee, The Mercury News this week in a press briefing in Essential's headquarters in Palo Alto. "People have neglected hardware for years, decades. The rest of the venture business is focused on software, on service." Essential wanted to make a timeless, high-powered phone, according to Rubin. Its bezel-less and logo- less design is reinforced by titanium parts, stronger than the industry standard aluminum parts, and a ceramic exterior. It has no buttons in its front display but has a fingerprint scanner on the back. The company is also making accessories, like an attachable 360-degree camera, and the Phone will work with products from its competition, such as the Apple Homekit. Essential, the new smartphone company founded by Android operating system creator Andy Rubin, "How do you build technology that consumers are is planning to ship its first pre-ordered flagship willing to invest in?" asked Rubin. "Inter-operability smartphones soon. The general launch date for is really, really important. We acknowledge that, the Essential Phone remains unknown, despite and we inter-operate with companies even if they months of publicity and continued intrigue among are our competitors." Silicon Valley's gadget-loving circles. Recently, Essential's exclusive carrier Sprint announced it While the 5.7-inch phone feels denser than its will open Phone pre-orders on its own website and Apple and Samsung counterparts, it is bereft of stores. Essential opened up pre-orders on its bloatware - rarely used default apps that are website in May when the product was first common in new smartphones. -
