  • Patent number: 10389287
    Abstract: Systems and methods for controlling a permanent magnet synchronous motor to eliminate the need to filter a PWM output of the motor's drive system. In one embodiment, the motor's drive transforms measured output currents to a d-q reference frame and uses these to determine demanded Vd and Vq voltages. An inverter angle is determined from the difference between the demanded Vd and Vq voltages. A demanded bus voltage is determined as the square root of the sum of the square of the demanded Vq and the demanded Vd, multiplied by 2/pi. An inverter angle is determined as the arctangent of (?demanded Vd/demanded Vq). The demanded and actual bus voltages are used to determine a firing angle for the converter. The controller uses this information to generate a six-step waveform that can be provided to the motor without requiring output filtering.

  • Patent number: 10366788
    Abstract: An administration set for an infusion pump includes a free-flow prevention device having a movable plunger that includes a cam surface defining an uneven profile along a direction of movement of the plunger, wherein the shape of the cam surface profile indicates the administration set is authorized for use with the infusion pump and may further indicate the specific type of administration set. A sensor in the infusion pump senses movement of the plunger as a platen of the infusion pump is latched and generates a profile signal in the time domain representative of the cam surface profile. A processor evaluates the profile signal and controls operation of the pump to protect a patient from improper loading of an administration set, use of an unauthorized administration set, and/or use of an invalid type of administration set for a chosen infusion protocol.

  • Patent number: 10294937
    Abstract: A pump for conveying liquid includes a pump housing having an inlet, an outlet, an inner circumferential surface and a geometric axis. An eccentric in the housing is rotatable about the geometric axis relative to the housing. A deformable element is disposed between the inner circumferential housing surface and the eccentric. A delivery duct from the inlet to the outlet is formed by the deformable element and the inner circumferential housing surface. The deformable element is pressed against the housing by the eccentric in sections so that a displaceable seal of the duct and a closed pump volume in the duct are formed and are displaceable to convey the liquid along the duct from the inlet to the outlet by rotation of the eccentric. A receptacle, accommodating an edge region of the deformable element, is formed by the inner circumferential housing surface and a counter bracket.

  • Patent number: 10145230
    Abstract: Systems and methods for improved monitoring of downhole pump conditions may provide real-time monitoring, high accuracy, and low noise when monitoring downhole pump conditions. Systems for monitoring pump conditions may be coupled to any suitable sucker rod pump, and may gather desired data from the pump. The desired data may be gathered at several points-in-time during a pump stroke to provide real-time monitoring. A wave equation corresponding to the behavior of the downhole pump may be solved when the desired data is received to provide real-time monitor. In some embodiments, the wave equation may be solved by separating it into static and dynamic solutions. In some embodiments, the dynamic solution of the wave equation may be solved utilizing an integral-based method.

  • Patent number: 10047737
    Abstract: A pump features: A motor having a front end bell (FEB) with a coupling portion having twist lock style (TLS) connections with locking portions, and an outer surface with a detent; and a pump head (PH) including a PH portion having a PH coupling portion with corresponding TLS connections and corresponding locking portions with locking stops. The PH portion has an outer surface having a threaded orifice. The TLS connections couple together when the FEB and PH coupling portions are pushed together. The locking portions engage when the FEB and PH coupling portions twist together about the longitudinal axis of the pump. The locking stops abut against the locking portions to stop the FEB and PH coupling portions from twisting further, so the detent and the threaded orifice align to receive the LP, locking the motor and PH together.

  • Patent number: 9964205
    Abstract: An electric oil pump (ELOP) provided in parallel to a mechanical oil pump driven by an engine supplies oil to a clutch of a transmission. The ELOP is rotated in advance of a request to operate the ELOP at a targeted relatively-low first preoperation rotational speed. When an actual rotational speed matches the first preoperation rotational speed and an actual current matches a threshold, the ELOP is rotated at a targeted relatively-high second preoperation rotational speed. At least when an actual rotational speed matches a second predetermined rotational speed not higher than the second preoperation rotational speed, it is determined that preoperation is completed. If the number of restarts during the preoperation as one operation history of the ELOP reaches or exceeds the predetermined number of times, the current supply to the ELOP is interrupted to limit the restart, thereby reducing the number of repeated restarts of the ELOP.
