  • Collaborative vehicle control using both human operator and automated controller input
    Patent number: 9464410
    Abstract: Control of a vehicle to perform a task employs first control input provided by a human operator and second control input provided by an automated controller. A relationship between the first control input and the second control input is determined. Either the first control input or the second control input is used to control the vehicle to perform the task based on the determined relationship. An indicator may be used to indicate to the operator when the control input provided by the human operator is being used to control the vehicle.

  • Peristaltic pump controller with scale factor that varies as a step function of pump inlet pressure
    Patent number: 5947692
    Abstract: A controller for a peristaltic pump receives as an input pressure P.sub.i sensed at the inlet of the pump. The controller derives a nonlinear scale factor S.sub.Pi that varies as a step function with P.sub.i. The scale factor S.sub.Pi equals a first nonvariable value when P.sub.i lays in a first defined zone of inlet pressures, and equals a second nonvariable value, different than the first nonvariable value, when P.sub.i lays in a second defined zone of inlet pressures different than the first defined zone of inlet pressures. The controller generates a pump speed command based, at least in part, upon S.sub.Pi.
