Slide Guide Used in Fluorescence Microscope

In the USA and other developed countries, cancer is responsible for 25% of all deaths. In spite of the most recent advances in cancer research, by far the best curative treatment for the disease is early detection. Such technology revolves around quick identification of malignant cells, necessitating clean, crisp images for oncologists. The CellTracks Analyzer II by Immunicon (Huntington Valley, PA) is a semi-automated fluorescence microscope system used to count and characterize fluorescently labeled cells that are immuno-magnetically selected and aligned. The SEBS-B type miniature slide guide, from NB Corp. of America (Wood Dale, IL), is tapped as part of the microscope’s system of axes.

High Flow Valve Used in Optic Processing Line

As the race to fulfill the ever-increasing demand for fiber optic assemblies began, the need for a fully automatic assembly line has come into focus. Individual filaments must be connected in such a way that the light traveling from strand to strand is not degraded. Owens Design (Fremont, CA) developed the custom Fiber Optic Assembly Line to join optic fibers and connectors. Using SMC’s (Indianapolis, IN) Series VQ5000 5-port solenoid valve as part of the feeder system, the assembly produces five types of fiber optic transducers.

Motion Controller Helps Test for Hard Disk Defects

Hard disks were originally intended for computers in ultra-clean, ultra-safe data offices; by the 21st century, hard disks had moved beyond the office, finding their way into digital cameras, video recorders, PDAs, and cell phones. With the ubiquity of hard disks comes the risk that any number of electronic devices can fail if their hard disk crashes. To detect hard disk defects while still in the assembly stages, THôT Technologies (Campbell, CA) developed the Model 42000, a laser-based test and measurement system for hard drives’ disks, using the DMC 1832 3-axis controller from Galil Motion Control (Rocklin, CA) to help monitor and regulate various systems of the Model 42000 as it conducts testing.

CNC Wood Routers Use Drive for Precision Control

The woodworking industry is as advanced and under pressure to deliver high-quality goods quickly as any. One of the most versatile tools devised to quicken production with flat panels of wood is the wood router, used to rout (hollow out) an area in the face of a piece of wood, and used for 3D design, cabinets, sign making, molds, and general material cutting. The table-like device, similar to a metal mill, consists of a broad-based wooden hand plane with a narrow gantry-carried cutting implement projecting beyond its base plate. To guide its computer numerical controlled (CNC) ATC wood routers, WartHog CNC (Soddy-Daisy, TN) turned to YET US’s (Manchester, NH) XtraDrive servo drive system, integrating it into the routers’ precision and power controls.

Drive Utilized in Filament Respooler

Optical fiber, now the mainstay of telecommunications as well as sensor, illumination, and imaging systems, is made by first pulling a large-diameter preform into a long, filimentous fiber. Then divided into bunches, a resin cladding is applied to keep the transmital of light uncontamintated. The finished product is then wound onto large spools to await shipment to customers. Showmark (Downingtown, PA) developed the automatic UniSpooler to customize the amount of cable a customer gets based on need, and uses the Kinemax KI3-15-5 linear drive from Amacoil/Uhling (Aston, PA) to help guide filaments from the supply spool to smaller takeup spool with the desired amount of fiber or wire.

Actuator Controls Valving in Micro-Satellite Thruster

In the 1980s and 1990s, NASA’s Jet Propulsion Laboratory (Pasadena, CA) began developing advanced microsystems and microelectronics technologies and components for future space applications. One of these experimental designs, the Micro-Inspector Spacecraft, is capable of visual inspection of a host space vehicle with support from NASA’s Exploration Systems Mission Directorate. The piezoelectric actuator in the Micro-Inspector’s propulsion system is from Dynamic Structures and Materials (DSM, Franklin, TN), and controls the many valves of the satellite’s engines.

Fiber Optic Rotary Encoder Helps Guide Aerial Tramways

In situations where human travel is necessary but where the geography is too steep or treacherous, aerial tramways often are used as a convenient alternative. Ski resorts, mountaineering centers, even archeological sites and cities with a diverse geography have tapped tramways as a method of transportation. When FREY AG (Stans, Switzerland) began constructing new aerial tramway systems, it turned to Micronor’s (Newbury Park, CA) fiber optic MR314 ZapFree™ high resolution hollow shaft rotary encoder to be part of the tramway’s positioning and cable systems.
