Depew, NY: The 261A Series triaxial force link sensors from the Force/Torque Division of PCB Piezotronics simultaneously measure dynamic and quasi-static forces in three orthogonal directions (X, Y, and Z-axes). The sensors are used during vibration testing of aerospace structures to match the mechanical impedance of shaker inputs and may be used to force limit the shaker controller to prevent damage to expensive structures. Other applications include cutting tool monitoring, biomechanics feedback, and automobile chassis dynamics. Series 261A comes preloaded between two plates, with a four-screw mounting pattern to allow easy installation and feature full-scale measuring ranges from 2.2 kN to 18 kN in the X and Y directions, and from 4.5 kN to 45 kN in the Z direction. Single axis models are also available. PCB Piezotronics Inc, Depew, NY, USA.
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.
