3D Navigation Devices

3Dconnexion(r), a Logitech company, San Jose, CA, has released two new 3D navigation devices, SpaceNavigator and SpaceExplorer, that provide designers with intuitive 3D computer navigation control. SpaceNavigator is an entry-level device that lets users move naturally and fluidly in 3D environments without making repetitive mouse movements or having to type multiple keyboard commands. It features six optical sensors that communicate multiple threads of navigation data to 3D applications. It is used as a companion to a mouse, in the alternate hand, and lets users simultaneously pan, zoom, and rotate 3D objects. A small, heavy steel base holds the device to the desktop and supports a controller cap that flexes in all directions. The SpaceExplorer is a mid-range device that features a key console and 15 pre-configured function keys within comfortable reach of the controller cap. It comes with 3DxSoftware, which offers support for Autodesk Design Reviewer and DWF Viewer, and Google Earth and SketchUp. For Free Info Visit http://info.hotims.com/10960-120

Bill Sheredy, Project Manager for SAME (Smoke Aerosol Measurement Experiment)

NASA Glenn Research Center, Cleveland, OH Bill SheredyFire is deadly and unpredictable on Earth; in an enclosed space vehicle in orbit, its presence takes on even more serious implications. To prevent the threat of smoke and fire on missions, NASA conducted the Smoke Aerosol Measurement Experiment (SAME), designed to create devices that will adequately detect combustion in a zero-gravity environment. Heading SAME is NASA researcher Bill Sheredy.

Product of the Month: Infrared Emitters & Sensors

O P T E K Technology (Carrollton, TX) offers the OP280 series of infrared emitters, and the OP580 series of matching silicon photo sensors. The OP280 emitter series consists of three standard devices: the OP180 940-nm infrared emitter, the OP280 880-nm infrared emitter, and the OP280K 890-nm infrared emitter; and the OP280PS 850-nm point source infrared emitter and the OP280V 850-nm vertical cavity surface emitting laser (VCSEL) device. The OP580 series of sensors consists of the OP580 phototransistor, the OP580PR silicon photodarlington, and the OP580RB silicon phototransistor with an integrated base-emitter resistor. The emitters and sensors are housed in standard PLCC-2 surface mount packaging, and are suitable for applications in industrial automation control, optical encoder equipment, and bar code readers.

Digital Servos, Software Chart New Directions in Optical Scanning

Optical scanners, or servo-controlled, limited-rotation motors with laser-beam steering mirrors, were first introduced 40 years ago by General Scanning. Since then, they have become the enabling technology behind many innovative products across many different industries, including medical imaging, industrial machining, product identification, biomedical research, automotive manufacturing, and many more.

Design Software Bridges Optical/Mechanical Gap for Life Sciences

The inherently interdisciplinary nature of developing instrumentation for life sciences requires a high level of collaboration between scientists and engineers across the fields of analytical or clinical chemistry, optics, mechanics, material science, and microbiology. Moreover, product development teams are competing for first-tomarket benefits that are driven by intellectual property lifetimes and insuring an installed base quickly to realize recurring consumable sales. Concurrently, product designers need to comply with current Good Manufacturing Practices (cGMP). System-level modeling enables adherence to the methodical design process without the cost and time associated with iterative hardware prototyping and laboratory and clinical testing.

Card Provides PCI-Based Multi-Axis Motion Control

Performance Motion Devices (Lincoln, MA) offers the Prodigy™-PCI motion card for multi-axis motion control. Available in 1-, 2-, 3-, and 4-axis versions, the card provides trajectory generation, performance trace, on-the-fly changes, and commutation. Motor type can be software- selected on a per-axis basis, and includes DC brush, brushless DC, step, and microstepping. The card communicates via a PCI bus, CANbus, or serial port. Card features include S-curve, trapezoidal, velocity contouring, electronic gearing, and user-generated profile modes. The card accepts input parameters such as position, velocity, acceleration, and jerk from the host, and generates a corresponding trajectory.
