-
System analysis and simulation using Matlab®
-
Product innovation, proof of concept, and outsourcing
-
Vertical and horizontal ride quality measurements
-
Motion control systems for high-rise elevators
-
Cost-effective, mass-produced elevator systems
-
Safety and control systems using radars and lasers
-
Electronic safety governors and techniques for elevators
-
Active roller guide and magnetic guidance systems
-
Design of various control circuits, sensors and actuators
-

-
Rotary and linear motors and drives (DC, induction, synchronous)
-
Automated people mover systems
Some specific product
related activities were:
-
Established motion control
technique used on Otis high-rise elevators since early 1980's
-
Proposed in mid 1980's and then
built active vibration controls to improve ride of high-speed, high-rise
elevators
-
Designed and built
low-cost linear-motor door operator
-
Tested motion controls and
active vibration controls on high-rise elevators.
-
Redesigned the Primary Position
Transducer used on high-rise elevators to improve performance and reduce
cost
-
Instrumental in introduction of
Matlab®
and other simulation tools.
-
Solved many dynamic controls
problems related to systems having structural resonances, nonlinearities,
and time-variable parameters
-
Employed vendors and consultants
in areas related to electronics and electromechanical apparatus
1972
- 1977:
