Apparatus are provided for motor control systems and related medical devices. In one embodiment, a control system includes a motor having a rotor, a sensor to obtain a measured displacement that is influenced by rotation of the rotor, and a control module coupled to the sensor. The control module adjusts a duty cycle for a modulated voltage applied to the motor in response to a difference between an expected displacement and the measured displacement. The expected displacement is influenced by or otherwise corresponds to a commanded rotation of the rotor.

A motor may be configured to drive a drive shaft and an engagement member supported on the drive shaft. A detectable feature comprising a rotary member may be supported on the drive shaft such that movement of the drive shaft by the motor changes a state of the detectable feature. At least one sensor may be arranged to detect the state of the detectable feature. Circuitry may be configured to provide a signal in response to a change in the state of the detectable feature detected by the at least one sensor.

Apparatus are provided for motor control systems and related medical devices. In one embodiment, a control system includes a motor having a rotor, a modulation module coupled to the motor, and a control module coupled to the motor and the modulation module. The modulation module generates a modulated voltage that is applied to the motor, and the control module adjusts a duty cycle of the modulated voltage to achieve a commanded rotation of the rotor and detects a degradation condition based on the duty cycle.

Motor health monitoring and medical device incorporating same

Apparatus are provided for motor control systems and related medical devices. In one embodiment, a control system includes a motor having a rotor, a modulation module coupled to the motor, and a control module coupled to the modulation module. The modulation module generates a modulated voltage that is applied to the motor and rotates the rotor to deliver fluid via a fluid path. The control module adjusts a duty cycle of the modulated voltage to achieve a commanded rotation of the rotor and detects an occlusion condition in the fluid path based on the duty cycle.

According to various embodiments, a user interface (UI) includes a precedence graph area and an icon list displaying multiple types of program icons. A user selection of one of the program icons is received, the user selection corresponding to moving the selected program icon to the precedence graph area, the selected program icon referencing a composer UI to generate content of a specific media type. The selected program icon is characterized as a first program-content-pairing icon that references the content created by the composer UI. Thereafter, a user interaction with a plurality of program-content-pairing icons in the precedence graph area is detected, the user interaction corresponding to specifying an ordering of the plurality of program-content-pairing icons. A program flow precedence graph referencing a program flow of an interactive program is the generated, based on the ordering of the program-content-pairing icons in the precedence graph area.
