Sub-Miniature Resonant Optical Scanner

The SC-3 Sub-Miniature Resonant Optical Scanner from Electro-Optical Products (Fresh Meadows, NY) is an electromagnetically driven moving mirror device that deflects a light beam with a continuous sinusoidal motion. The scanning frequency range is from 100 Hz to 1000 Hz, fixed at any one value within the range. High device “Q” insures frequency stability, low reaction forces, and low electrical drive power. High flexural stiffness provides good resistance to shock and vibration, as well as low wobble, and good scan repeatability.

USB-Equipped Cameras

The CMOS camera models ProgRes® CT1, CT3 and CT5 from Jenoptik (Jena, Germany) are now equipped with USB interface. With an extended resolution up to 5 Megapixel and a live frame rate up to 20 fps the new USB Camera of the CMOS Line delivers faster high resolution with excellent image results. New in the ProgRes® CCD Research Series are the USB Models ProgRes® CS and MS. These extraordinary and very sensitive cameras perform high sensitive imaging with up to 50 fps in full resolution (CCIR/PAL). You can also get the ProgRes® CF and MF cameras now with USB interface with faster live imaging in SXGA resolution with 15 fps.

RTA Polygonal Scanners

Lincoln Laser (Phoenix, AZ) has announced a new family of RTA Polygonal Scanners. You may select a precision ball bearing motor for operation from 500 to 12,000 RPM or a self-generating air bearing motor for operation from 10,000 to 55,000 RPM. Polygonal mirrors are stocked in standard sizes from 18 to 90 facets. This family of mirrors and motors covers scan rates from 150 Hz to 85 KHz. Standard mirror coatings are for Infrared lasers. For a moderate extra cost and longer lead-time, users can specify a custom mirror for these motors and associated controllers.

Digital Welding Camera System

Invisual E. Inc. (Toronto, Canada) has introduced the ICAM digital weld viewing and monitoring system as a tool for improving welding automation. The ICAM system extends the operatorís view of the weld zone by providing real time display and capture of the weld arc. The camera is a standalone smart camera with rich I/O and an onboard programmable area. Features include: compliance with protection standards DIN 3-7 (gas welding) and Din 9-13 (electro welding); dynamic range > 140dB; auto brightness and exposure adjustment; no blooming effects or image artifacts in scene; reticule overlay; ICAM software to access system parameters.

Using Event Systems and DMA to Cut Power Consumption

The trick to exploiting the ultra lowpower characteristics of microcontrollers with 100 nA sleep mode power consumption is to keep them in sleep mode as much as possible. The problem is that the growing number of on-chip peripherals and the increasingly dataand interrupt-intensive nature of modern applications make this a very difficult objective to achieve.

Using Dynamic Parameters to Measure Digitizer Performance

Much confusion exists about characterizing the performance of a highspeed digitizer device. Nominal vertical resolution is routinely presented as an indicator of a digitizer’s performance, but the relevance of this parameter is dubious since a digitizer’s true performance is characterized by the Dynamic Parameters*.

Designing Versatile COTS Data Acquisition Systems

Designing a versatile data acquisition (DAQ) system begins by comparing features of the signal of interest to the capabilities of current state-of-the-art A/D converters. Specifically, signal bandwidth and maximum signal frequency are compared to the A/D maximum sampling rate and bandwidth. The specifications in Table 1 are typical of current A/Ds.

Moving Machine Vision to 64-Bits

A nearly geometric growth in the data requirements for many machine vision applications is pushing 32-bit processing to its limits. The challenge is not in processing power, however, but in addressing memory buffers as systems fill them with ever-increasing volumes of data. Moving vision systems to 64-bit operation can solve the data challenge, but will require fully-updated hardware and software support.

Jeff Ding, Aerospace Welding Engineer at NASA Marshall Space Flight Center

Jeff Ding introduced friction stir welding (FSW) to NASA in 1995. He currently holds 6 U.S. patents for FSW, including one for an automatic retractable pin tool that solves the troublesome “keyhole” problem. He is also credited with inventing two new solid state welding processes called thermal stir welding (TSW) and ultrasonic stir welding (USW). Ding was Marshall Space Flight Center’s Inventor of the Year in 2000, was awarded the Medal for Exceptional Technology Achievement in 2003, and recently received the 2009 Federal laboratory Consortium Award for Excellence in Technology Transfer.
