Jaz is a family of
stackable, modular components with common electronics and communications. At
its heart is a miniature CCD-array spectrometer, available with optical bench
design options to optimize the system for various application needs. The Jaz
platform accommodates up to eight spectrometer channels for multi-channel
sensing. Each Jaz stack includes an onboard
microprocessor and display, which eliminate the need for a PC. Spectral data
can be acquired, processed and stored onboard the unit or transmitted via
Ethernet or USB to another device. Applications software and programming
options allow users to customize the system interface to their requirements. Design
engineers tasked with the requirement to measure light no longer need to
become light-measurement experts. Complete systems, including light source
and spectral measurement, and even communications and storage, can all be
implemented quickly and easily using the battery-powered, field-ready Jaz
spectrometer system. Modularity and versatility mean a custom system
can be created off-the-shelf to solve an almost infinite variety of measurement
and control problems -- and measure light, oxygen, pH, temperature, voltage or
current. Once satisfied that the Jaz does the job, customization options
mean that an OEM-ready product can be available in record time. Jaz is a
breakthrough that eliminates obstacles associated with traditional spectral
systems; nothing similar exists. For example, researchers using Jaz scaled Mt.
to make solar radiation measurements, providing important data about ozone
depletion. Existing alternatives, encumbered by computer needs and power
supplies, are untenable for such applications. Similarly, Jaz has enabled
complex analyses in environments as challenging as snow fields in Norway
and strictly controlled greenhouses in The Netherlands. What really sets the
product apart, besides its configurability and size, is that Jaz uses only 2.5W
of power while running an embedded OS (ucLinux) and powering an onboard
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
