Sealed-Off Ignitrons for Welding Control
Transactions of the American Institute of Electrical Engineers, 1937Accurate control of high currents for resistance welding may be obtained by igniter-type mercury-cathode tubes capable of conducting 7,000 amperes in impulses of from less than 0.01 second to several seconds duration. This paper describes design principles and manufacturing technique for tubes of the sealed-off type.

Successful Application Of Pump-Off Controllers
SPE Annual Fall Technical Conference and Exhibition, 1977Abstract One of the major sources of problems associated with rod pumping is pump-off and the associated fluid pound. After several pumping is pump-off and the associated fluid pound. After several years or development, techniques and systems are available to reliably detect and control pump-off.

Hybrid control in automotive applications: the cut-off control
Automatica, 1999A novel approach to the control of an automotive engines in the cut-off region is presented. First, a hybrid model which describes the torque generation mechanism and the powertrain dynamics is developed. Then, the cut-off control problem is formulated as a hybrid optimal control problem, whose solution is obtained by relaxing it to the continuous ...

Control of the heel-off to toe-off motion of a dynamic biped gait
IEEE Transactions on Systems, Man, and Cybernetics, 1992A mechanism for the control of the heel-off to toe-off motion of a dynamic biped gait is presented. It is argued that the reaction force between the ground and the biped foot is an important factor in a satisfactory implementation of dynamic gait. This force must be properly controlled while the foot is in the heel-off to toe-off phase.
