Neumarkt, Germany: The DSM surge arrester from Dehn is designed to protect telecommunications equipment from the effects of electrical surges due to lightning or electrical switching. The compact protector is ideally suited for installation into flush-mounted boxes or small enclosures, while the use of removable plug-in terminals makes installation very straightforward and simple. In a typical installation, the DSM is fitted at the socket outlet of the telecommunications equipment being protected. This will provide a high level of protection to any connected equipment for minimal cost. The family of DSM arresters includes models for two or four standard lines and ISDN versions.

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.
