Keith Lofstrom is an American electrical engineer. He has a BSEE and MSEE from University of California, Berkeley.〔 〕 He is more widely known in the space advocacy community for a ground-based space launcher design, the Launch Loop,〔 〕〔 〕〔 〕 for which he has been credited by name in several works of science fiction.〔 〕〔 〕〔 〕〔 〕 Frederik Pohl, who used the idea in several of his stories, once wrote that, of all the non-rocket spacelaunch concepts, he liked the Lofstrom Loop "best of all."〔 〕 As an electrical engineer, Lofstrom specializes in mixed-signal integrated circuit design. A paper he wrote on boundary scan methods was one of two to receive an Honorable Mention at the 1997 IEEE International Test Conference.〔 () 〕 One of his 9 patents is for a way to read an individual digital ID for integrated circuits that arises from random atomic variations inherent in the semiconductor device fabrication process.〔 〕〔(【引用サイトリンク】 url = http://www.siidtech.com/index.html ) 〕〔 〕 One of his more recent efforts in speculative space systems is Server Sky, a very large satellite constellation in Earth orbit using thin-film solar cells to power data center computers integrated into the same wafers as the PV cells.〔 〕 == See also == * Lofstrom loop 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Keith Lofstrom」の詳細全文を読む スポンサード リンク
