Apple Patent Hints At Wirelessly Charging Your iPhone Via Wi-Fi Routers

Slashdot - Fri, 04/28/2017 - 12:00
According to AppleInsider, "Apple is experimenting with medium- to long-distance wireless charging technologies that could one day allow users to charge up their iPhones with nothing more than a Wi-Fi router." From the report: Detailed in Apple's patent application for "Wireless Charging and Communications Systems With Dual-Frequency Patch Antennas" is a method for transferring power to electronic devices over frequencies normally dedicated to data communications. In its various embodiments, the invention notes power transfer capabilities over any suitable wireless communications link, including cellular between 700 MHz and 2700 MHz, and Wi-Fi operating at 2.4 GHz and 5 GHz. More specifically, the document's claims apply to millimeter wave 802.11ad spectrum channels currently in use by the WiGig standard, which operates over the 60 GHz frequency band. Theoretically, the proposal opens the door to wire-free charging from in-home Wi-Fi routers to cellular nodes and even satellite signals. Of course, amplitude in a wireless system is normally a function of distance. Like conventional wireless charging techniques, Apple's design requires two devices -- a transmitter and receiver -- to function. Each device contains one or more antennas coupled to wireless circuitry capable of making phase and magnitude adjustments to transmitted and received signals. Such hardware can be employed in dynamic beam steering operations.

NASA Delays First Flight of New SLS Rocket Until 2019

Slashdot - Fri, 04/28/2017 - 09:00
schwit1 writes: Despite spending almost $19 billion and more than thirteen years of development, NASA today admitted that it will have to delay the first test flight of the SLS rocket from late 2018 to sometime in 2019. "We agree with the GAO that maintaining a November 2018 launch readiness date is not in the best interest of the program, and we are in the process of establishing a new target in 2019," wrote William Gerstenmaier, chief of NASA's human spaceflight program. "Caution should be used in referencing the report on the specific technical issues, but the overall conclusions are valid." The competition between the big government SLS/Orion program and private commercial space is downright embarrassing to the government. While SLS continues to be delayed, even after more than a decade of work and billions of wasted dollars, SpaceX is gearing up for the first flight of Falcon Heavy this year. And they will be doing it despite the fact that Congress took money from the commercial private space effort, delaying its progress, in order to throw more money at SLS/Orion.

Kill Net Neutrality and You'll Kill Us, Say 800 US Startups

Slashdot - Fri, 04/28/2017 - 05:30
A group of more than 800 startups has sent a letter to the FCC chairman Ajit Pai saying they are "deeply concerned" about his decision to kill net neutrality -- reversing the Title II classification of internet service providers. The group, which includes Y Combinator, Etsy, Foursquare, GitHub, Imgur, Nextdoor, and Warby Parker, added that the decision could end up shutting their businesses. They add, via an article on The Verge: "The success of America's startup ecosystem depends on more than improved broadband speeds. We also depend on an open Internet -- including enforceable net neutrality rules that ensure big cable companies can't discriminate against people like us. We're deeply concerned with your intention to undo the existing legal framework. Without net neutrality, the incumbents who provide access to the Internet would be able to pick winners or losers in the market. They could impede traffic from our services in order to favor their own services or established competitors. Or they could impose new tolls on us, inhibiting consumer choice. [...] Our companies should be able to compete with incumbents on the quality of our products and services, not our capacity to pay tolls to Internet access providers."
