Man-Machine Interface Requirements

• Electronically controlled interfaces and control-by-wire becoming standard in industrial, agricultural and mining equipment applications.

• Robustness and survivability requirements are driven by need to minimize warranty repairs and equipment down time.

• Reliability requirements present in these environmentally challenging applications are significantly higher then those found in commercial and light industrial applications

Position Proportional Approach

Advantages– Easier for untrained people to use

– More intuitive

– Has easily definable end conditions

Disadvantages– Requires extra space for movement of handle

– More complex internal mechanism

– More prone to wear and degradation in conventional joysticks

– Lower precision

Force Proportional Approach

Advantages– Highly precise

– Smaller Space requirements in system

– Less complexity in input device

– Higher reliability

Disadvantages– Not intuitive for untrained operators

– Over-force potential

04/13/23 7

Non-Proportional Approach

Advantages– Low Cost

– No over-force protection required

Disadvantages– Can only control on-off functionality

– Switches are unreliable

– No precision

Approaches to Man-Machine Interface

Standard Position Proportional Solutions– Potentiometer based joysticks

– Optical joysticks and input devices

– Hall-effect input devices

– Industrial high-rel switches

Force Proportional Solutions– Strain Gages based systems

Non-Proportional– Switches are activated when levers are moved

The Bokam Approach

Adapt High Reliability Sensor Technology to Input Devices to create systems that:

• High reliability and extreme live

• Have no moving or rubbing parts that can wear over time

• Provide Both a force proportional and a position proportional configuration in the same basic package size

• Develop an input device product line based on building blocks that can be combined to solve the most obscure application requirements without substantial NRE effort

• Create a cost sensitive product line.

The Base Technology

Engineering Inc.


Bokam

� Application and firing of strain sensitive materials directly into the diaphragm or substrate.

� Resulting element contains an imbedded set of strain gauges that do not rely on bond lines or epoxy for adherence to the substrate.

� Elements are deposited onto the substrate in a full whetstone bridge configuration.

� New proprietary processing techniques have been developed to allow for the deposition of strain gauge materials onto stainless steels and pin-corrosion resistive steels while maintaining dielectric isolation between the gauge and the base material.

� Proprietary barrier creation materials and processes are used to limit ion migration and create extreme temp solder joints.

� Un-amplified outputs of full bridge sensor with 10V applied can be as high as 150-200mV (with 100mV as typical output with high safety margin)

� Operating temperatures from cryogenic to 500F

� Output stable over time and temperature

� Technology and processes adaptable to low cost high volume OEM applications
