LPC-350-PCI Little PC

Stealth Computer Corp., Woodbridge, ON, Canada, has introduced the LPC- 350PCI Little PC, a mini personal computer that can fit in the palm of your hand. The anodized aluminum chassis measures about 2" tall, and has the overall footprint the size of a hardcover book, measuring 10 × 5.87 × 2.75", and weighing 6 pounds. The rugged computer uses Intel’s Pentium and Celeron M processors and features I/O connectivity such as LAN, serial, 3 USB 2.0, FireWire, video, audio, and PS/2 mouse and keyboard ports. Other features include an open PCI card slot for adding specialized I/O and data acquisition and communications cards, a built-in 2.5" highshock hard drive with up to 160 GB of storage space for archived data, and an optional solid-state hard drive or Flash drive. A DVD/CD-RW optical drive offers an optional DVD burner. Systems are compatible with Microsoft XP and Vista, as well as Linux. For Free Info Visit

David Iverson, Computer Scientist, NASA’s Ames Research Center, Moffett Field, CA

The Inductive Monitoring System (IMS) is a new computer program that monitors gyroscopes that keep the International Space Station properly oriented in space. IMS detects warning signs that precede a gyroscope’s failure. Engineers will add the new software to a group of existing tools to identify and track problems related to the gyroscopes. If the software detects warning signs, it will quickly warn the space station’s mission control center. David Iverson developed the software at NASA Ames.

LED-Equipped Spectrophotometers Find Their Way to the Factory Floor

Companies that manufacture products ultimately used by consumers — interior trim for cars, vinyl siding for homes, decorative stone for landscaping, interior wall paints, etc. — are often discovering that they need to use precise spectrophotometers to ensure first-time color quality and lotto-lot consistency.

Improving Lens Performance With Transmitted Wavefront Error Testing

During design and manufacturing, optical systems and lenses are toleranced and tested to ensure the smallest possible performance error. Matching most optics manufacturing companies’ capabilities, lenses are traditionally toleranced with individual surface specifications — surface power and irregularity, or form, error. These tolerances and the associated tests control performance of a single surface, not the entire lens. Because lens designs are built around transmission characteristics such as spot size and RMS wavefront error, the performance of the entire lens, not the individual surfaces, is the true target. Transmitted wavefront error (TWE), which is the error in transmission of light through a lens, is the true target. For aspheric surfaces, traditional single-surface, three-dimensional surface form metrology is not easy. Aside from testing the true target, it may be easier and faster to make use of TWE for aspheric lenses. Using innovative metrology and developing a feed-forward manufacturing strategy, tolerancing and testing TWE can reduce risk in optical designs, improve performance and reduce cost and lead time.

Light Pipe Homogenizing Rods

Edmund Optics (Barrington, NJ) announces the release of the TechSpec™ family of light pipe homogenizing rods for OEM illumination needs. The rods use total internal reflection to turn a non-uniform light source into uniform illumination and deliver it to the target site. These rods are ideal for applications where point sources such as LEDs must be combined and made to deliver even lighting.
