Track System

Accuride (Santa Fe Springs, CA) introduced the Model AL4190 Tilt Track System that provides access to drawers or trays installed at shoulder level and above. The system uses wheels and rollers to extend the drawer, and an aluminum channel guides the back of the drawer upward as it slides out of the case, tilting the drawer downward for easy viewing and access to contents. The system carries drawers up to 40" wide and loads up to 140 pounds. The system is comprised of lightweight, corrosion- resistant aluminum tracks, roller wheel assemblies, and track rollers. Tracks are available in lengths of 24" and 40". The system is fully adjustable with the drawer in place. The installer can alter the angle of the tilt, which varies based on the angle of the track, attachment location of the track roller, and positioning of bumper stops.

Actuators

Nook Industries (Cleveland, OH) offers Series 500™ programmable actuators designed for continuous duty and long service life. They incorporate a direct or toothed-belt drive for high mechanical efficiency. Ball screw-driven programmable actuators are made with high-strength materials, and are available in parallel and in-line models with either a servomotor or stepper motor. The screw shaft is constructed with medium-carbon, induction-hardened alloy steel, and the ball nuts are manufactured from high-grade bearing steel. Both ball screw and nut are heat-treated to a surface hardness of 56 HRC.

Accelerometer Chips

Silicon Designs (Kirkland, WA) offers industrial-grade MEMS variable capacitive accelerometer chips and modules for zero- to medium-frequency instrumentation applications. Onboard voltage regulation and an internal reference minimize temperature and voltage changes while eliminating additional external power regulation requirements. Each sensor is made to be virtually identical, allowing users to swap out parts in the same g range with few to no testing modifications. This also provides a plug-and-play solution for almost any application.

Bonded Magnets: A Versatile Class of Permanent Magnets

Permanent magnets are ubiquitous in modern societies. Devices which use permanent magnets include motors, sensors, actuators, acoustic transducers, etc. These are used in home appliances, speakers, office automation equipment, aerospace, wind turbine generators, medical laboratory diagnostic test equipment, and more. It is estimated, for example, that a typical automobile uses up to 120 permanent magnets in windshield wipers, starter motors, seat adjusters, door lock actuators, fuel pumps, sensors, gauges, etc. The development of Hybrid Electric Vehicle and Electric Vehicle drive technologies has been greatly enhanced by the availability of high performance magnetic materials.

Reducing Power-On/Off Glitches in Precision DACs: Part 2

Part 1 of this article introduced a phenomenon called power-on/off glitch. The example discussed the impact of this phenomenon on a motor control system. We limited our analysis to a DAC where the output buffer is powered on in normal mode: zero-scale or mid-scale. In Part 2, we analyze when the DAC output is powered on in high-impedance mode. We present a mathematical model for the power-on glitch, followed by board-level solutions to minimize it.

Autonomous Robots Keep Warehouse Running Green

YLOG, a startup company in Austria, uses an intelligent and very environmentally friendly logistics system that is winning an increasing number of customers. The technology makes use of individual, freely moving Autonomous Intelligent Vehicles (AiVs) that detect each other, observe right-of-way rules, recognize one-way routes, and complete their tasks fully autonomously without intervention from or coordination by a central computer.
