    Abstract: A rinsing device, in particular for endoscopy, comprising an electrically driven pump, in particular a peristaltic roller pump, as well as a method of operating such a device. A control device is provided to detect and/or adjust a flow rate. In order to avoid an excessively high pressure in case of an unintended stenosis, e.g. kinking of the supply tube, or also intended stenoses, e.g. insertion of a narrow rinsing probe, a current-measuring device is provided to detect a current being received by the pump. The control device is adapted such that when the flow rate exceeds a prespecified limiting value and at the same time the current exceeds a first predetermined current value, the flow rate is reduced to a safe flow-rate value.

    Abstract: In a pump control apparatus that controls the discharge of brake fluid using the rotation of a motor, the number of windings in a low speed circuit is set such that the motor operates at a second rotation speed when the low speed circuit is connected to a power supply. A high speed circuit shares a portion of the windings of the low speed circuit so that the motor operates at a first rotation speed when a power supply voltage is supplied to an input terminal which is disposed midway in the windings of the low speed circuit. An ECU determines the load state of the motor based on a difference between the output voltage at an output terminal and the power supply voltage.

    Abstract: A sensor module for a compressor having an electric motor connected to a power supply and a processor disposed within an electrical enclosure of the compressor is provided, with the electrical enclosure being configured to house electrical terminals for connecting the power supply to the electric motor. The sensor module includes a first input connected to a voltage sensor that generates a voltage signal corresponding to a voltage of the power supply and a second input connected to a current sensor that generates a current signal corresponding to a current of the power supply. The processor is connected to the first and second inputs. The processor may calculate a power factor of the compressor, detect an unexpected variation in the power supply, and/or detect a mechanical malfunction of the compressor based on the voltage measurements and the current measurements.

    Abstract: A method is provided for the electrical protection of an electrical household appliance that is used to prepare food. The appliance includes an electric pump which is supplied with alternating current in order to convey a liquid through a conduit and a heating element in order to raise the temperature of the liquid. The instantaneous value of the current I supplied to the pump is measured at regular time intervals. The method includes calculating the average value αn of the current I measurements m taken over a pre-determined time period T; comparing the average value αn with a reference value αref calculated as the average value of the current I measurements taken over an earlier period of the same length; and opening the pump supply circuit when the difference between the average values αref and αn exceeds a pre-determined threshold value Δ1 for at least two successive time periods T.
