Unlike low frequency ac-dc front ends using
a PFC boost stage and a dc-dc down converter, Vicor Corp.'sPFM VI
BRICK module provides isolation, voltage transformation and PFC regulation
in a single stage using advanced, high-frequency soft switching technology. Its
thin profile liberates system architects from dimensional constraints of bulky power
supplies. Its small size, coupled with secondary-side energy storage at 48V,
allows greater flexibility and creativity to design slim products with
competitive advantages. Its modular, scalable power component functionality
supports efficient, cost-effective power systems with 'N+1' redundancy.
This initial PFM module complements an array of VI BRICK
and V.I Chip converter building blocks that Vicor Corp. says provides unparalleled density, efficiency and connectivity from
the wall plug to the point of load.
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
