We serve clients with a range of services from turnkey custom system design to licensed intellectual property.

We offer the following services:

  • System engineering: mechanical, electrical and control systems analysis and design.
  • Precision engineering: air-bearing design, error analysis, kinematic and dynamic analysis, finite-element analysis.
  • High performance actuator design and manufacture.
  • Prototype design, fabrication and evaluation.
  • Turnkey system build.
  • Manufacture of critical components and sub-systems.

Example solutions include:

  • Novel, high-performance 6DOF wafer chuck for semiconductor equipment (US patents 6,756,751 & 6,822,407).
  • Short stroke actuator for precision machining operations: 15 G acceleration,   25 mm stroke, 1 M/sec, ~5 nM precision.
  • Synchronized, high-performance controller providing multi-Gflop compute power, virtually unlimited I/O expansion and sub-nsec jitter between all elements in the distributed control system.
  • Adaptive control technology that self-compensates for errors in encoders, motors and amplifiers thereby enabling unprecedented precision using moderately priced components.
