Microstar II is designed to offer measurements of vehicle dynamics parameters
such as driving performance, longitudinal determinations, fuel consumption and
off-road vehicle speed and distance measurements on jeeps, quads and ATVs, as
well as industrial utility, military transport and agricultural vehicles.
design of the Corrsys-Datron Microstar II incorporates use of
Doppler radar effect technology within a planar antenna system, which projects
two radar beams at 45 degree angles to measure relative movement between the
sensor and test surface. The non-contact system consists of the sensor
head antenna and a new Corrsys-Datron sensor electronics unit with 2.0B CANbus,
RS-232 serial port and a full-speed USB 2.0 port. Upon striking the test
surface, beams are reflected back to the sensor antenna. The resultant double
frequency, which is equal to the difference of sent and received frequencies,
is directly proportional to speed. The gained signal is then converted to
desired dimension via a high-performance onboard RISC digital signal processor
and sent to corresponding analog (-10 to 10 V) or digital (1 to 1,000 Pulse/m)
TTL outputs, with automatic compensation for both mounting and pitch-angle
a working distance range of 300 to 1200 mm and a speed range of 0.5 to 400 km/h
at a measurement frequency of 250 Hz, the Microstar II can be used in utility
and off-road vehicle applications requiring larger stand-off distances. It can
also be used within more challenging environmental conditions, such as in
wooded, mountainous or other heavy terrain areas, where use of traditional GPS
and optical sensing technologies are simply not possible. The sensor can also
accommodate additional connections, such as an interface for fuel
flow-measurement systems (for fuel consumption tests) and trigger inputs for
light barriers or brake switches.
used with supplied CeCalWin Pro Software, the Microstar II functions as a
complete vehicle data acquisition and evaluation system. Associated software
functions enable test parameters and definitions to be permanently saved, along
with charts, plots and other online displays and evaluations. In addition, all
measured signals can be saved and evaluated off-line.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
