Description of Technology and Product Line
Evolving from the best characteristics of Bokam's award-winning
imbeded, strain sensitive technology, the Motion control product
line offers products ranging from large robust palm activation
systems to tiny, yet robust devices that are a more economical
and reliable alternative to conventional multi-axis proportional
joy sticks.
Originally developed for stringent military and industrial man-machine interface applications, the product lines ruggedness, long cycle life and water resistance (The
device has even been demonstrated working while submerged in boiling water) make it an ideal input device for cursor and motion control in OEM packages as diverse as medical equipment, military, industrial and other
ruggedized man-machine interface packages, test and measurement instrumentation, and other motion control systems.
General Functionality
Figure 1: Cross-section of Sensor Body
In the middle of the sensor body there is a cavity with a post containing a tapped hole. This allows
the customer to interface any application specific input post or handle configuration. The X and Y coordinates of the sensor are in plane with the diaphragm the Z axis is aligned along the central axis
of the post. The sensor contains imbedded strain sensitive artwork located on the bottom surface of the sensor.
Figure 2: X/Y Force Input Magnified Deflection
Figure 3: Z Force Input Magnified Deflection
When an X, Y, or Z force is applied onto the sensor the diaphragm microscopically deflect creating a
change in signal from the strain sensitive bridge. Figure 2 and Figure 3 represents a grossly exaggerated deflection of the leaves during force application. The relationship between the change in
output is linear and proportional which allow the input device to control both the position of an object and also its rate of motion. Due to the rugged nature and force sensor basis of the technology and
design the input device allows not only precision motion control but in a package with a life expectancy longer than that of the OEM unit it is used in.
