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.
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.
