CompanyName ProductName Duesseldorf, Germany ALPS Electric has developed the HMLSR Series of Liqualloy magnetic sheets for radio frequency identification (RFID) applications. The magnetic sheets utilize ALPS’ Liqualloy metallic glass powder to boost the sensitivity of RFID antennas. The product enhances electromagnetic compatibility (EMC), eliminating the problem of interference with waves that should reach the wireless tag from radio or electromagnetic waves generated by nearby parts and devices. The amorphous structure of Liqualloy allows a high degree of freedom in the shaping process, and it displays soft magnetic properties that can be readily activated by exposure to magnetic fields. In addition, its high permeability is 1.3 times greater than that of Fe-Al-Si alloys, the leading magnetic material, giving it superior capacity to absorb radio and electromagnetic waves. In RFID technology, it is not unusual to install parts and devices on the back of wireless tag antennas, eventually causing interference with waves that should reach the antenna. The Liqualloy magnetic sheets effectively focus waves to the antenna, increasing RFID antenna sensitivity. Alps Electric Europa GmbH , Duesseldorf, Germany. www.alps-europe.com.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
