Abstract: According to an aspect, a system for stimulating muscle comprises a set of stimulators to stimulate a first muscles, a set of sensors providing first measurement comprising a set of electromyograms (EMG) from another set of muscles coupled to the body part, a set of sensors mounted in the vicinity of the set of stimulator and the set of sensors, providing a measurement representing a motion and orientation of the first body part, another set of sensors providing a measurement representing a condition external to the body part, a processor generating a first position of the body part at a first time instance from the measurements and a processor adjusting at least one of a time duration, trigger instance, and trigger strength of the set of stimulator. In that, the comparator generates a position error as difference between the first position and a reference.

Abstract: A method of reducing plant emissions includes providing a MPC model for a flaring process including one-to-one models between controlled variables (CVs) including a smoke count and/or a flare count (CV1) and a noise level (CV2), and flow of assist gas as a manipulated variable (MV) and another process gas flow as a disturbance variable (DV). The MPC model receives sensed flare-related parameters during the flaring process including a measure of CV1 (CV1*) and CV2 (CV2*). Provided CV1* is above a minimum setpoint for CV1 (CV1 setpoint) and CV2* is above a setpoint for CV2 (CV2 setpoint), the flaring process is automatically controlled using the MPC model which determines an updated flow setpoint for MV from CV1* and CV2*, the CV1 and CV2 error, and the identified one-to-one models.

Abstract: A flare monitoring and control system monitors parameters that affect the amount of smoke generated during a flaring operation. The system receives data relating to the parameters, and analyzes the data relating to the parameters. The system predicts an impending increase in the amount of smoke generated during the flaring operation, and varies a value of one or more parameters to prevent the impending increase in the amount of smoke generated during the flaring operation.

Abstract: A method comprises receiving a first frame from at least one imaging device, receiving a second frame from the at least one imaging device, analyzing at least a portion of the first frame and at least a portion of the second frame, and indicating when at least one of a zero velocity update and a zero attitude update should be performed based on at least in part on the analysis of the at least a portion of the first frame and the at least a portion of the second frame. The first frame is captured at a first vantage point and the second frame is captured at a second vantage point.
