    摘要: A motor drive device and a motor drive method for a vehicle electric pump. The device and the method set a target value according to an instruction value of a motor control amount and control the motor of the vehicle electric pump based on the target value. When the instruction value is greater than an actual control amount, the instruction value is set to the target value. Meanwhile, when the instruction value is less than the actual control amount, the actual control amount is set to the target value when the actual control amount is less than a value less than a previous target value by a predetermined value, and the value less than previous target value by predetermined value is set to the target value of this time when the actual control amount is greater than the value less than previous target value by predetermined value.

    摘要: Embodiments of the invention provide a pumping system and method including a flow locking feature. A pump controller includes a user interface configured to initially receive and set a plurality of programmed flow rate settings, a maximum locked flow rate, and a minimum locked flow rate. The pump controller is also configured to disable resetting of the maximum flow rate and the minimum flow rate once they are initially received and set and to allow resetting of the plurality of programmed flow rate settings throughout operation of the pumping system. The pump controller is further configured to operate a pump motor in order to maintain a first flow rate set by one of the plurality of programmed flow rate settings as long as the first flow rate is between the minimum locked flow rate and the maximum locked flow rate.

    摘要: The fluidic system with an unclogging feature of the preferred embodiment includes a flow channel, a sheath pump to pump sheath fluid from a sheath container into an interrogation zone, and a waste pump to pump waste fluid from the interrogation zone into a waste container. The sheath pump and/or the waste pump draw sample fluid from a sample container into the interrogation zone. The fluidic system also includes a controller to adjust the flow rate of the sample fluid from the sample container into the interrogation zone. The pump and controller cooperate to propagate a pulsation through the flow channel from the pump if the flow channel is clogged. The fluidic system is preferably incorporated into a flow cytometer with a flow cell that includes the interrogation zone.

    摘要: A pump control system includes a plurality of different variable speed pumps. Each of the pumps can be operated at a different speed to equalize pump loads. A system wide proportional integral differential control loop increases and decreases the speed of all pump motors to maintain a desired system output pressure. A second proportional integral differential control loop associated with each pump adjusts pump speed to equalize a load profile for each respective pump.

    摘要: Equipment for controlling blood flow in an extracorporeal blood circuit, comprising at least a first sensor, designed to measure an arterial pressure upstream of a peristaltic pump, at least a second sensor, designed to measure an angular velocity of a peristaltic pump, a memory designed to store at least one set value of the desired blood flow through the access branch, a calibration function, and a control unit. The calibration function has at least variables (v1), related to the angular velocity of the pump, (v2), related to the arterial pressure in a portion of the access branch upstream of the peristaltic pump, (v3), related to an actual flow of blood through the access branch. The control unit is capable of calculating an actual flow value by applying the calibration function to the values of angular velocity and arterial pressure measured by the sensors, comparing the actual flow with the desired flow, and varying the angular velocity of the peristaltic pump if the actual flow value minus the desired flow lies outside a predetermined range.
