Abstract: The present invention relates to a breast pump (1) for extracting milk from a female breast comprising an expression kit (2), a container (5) connected to the expression kit (2), and a vacuum unit (6) connected to the expression kit (2), wherein the combined volumes of the expression kit (2), the container (5), the vacuum unit (6) and the connections thereof define a system air volume, and a vacuum pressure sensor for determining volume changes in the system air volume in response to changes in vacuum pressure.

Abstract: A system (1) for monitoring living beings, such as persons, pets or livestock comprises a monitoring device (10) for monitoring a living being and a user device (20), such as a smartphone, which devices are arranged for communicating via an internet type connection (40), and a server (30) arranged for communicating with the user device (20) via a further internet type connection (50). The server (30) is provided with a software program for periodically initiating, through a software program in the user device (20), a protocol for testing the internet type connection (40). The system is thereby capable of detecting a loss of the internet type connection (40) between the monitoring device and the user device.

Abstract: A breast pump system includes a solenoid valve and a power source. The power source is arranged to supply electrical power to the solenoid valve so as enable the solenoid valve to move between first and second positions. The breast pump system also includes a controller configured to detect a change in inductance of the solenoid valve that is indicative of the solenoid valve moving from first to second position and a control action in which the vacuum pump is stopped.

Abstract: The present application relates to a breast pump system comprising a vacuum pump, an actuator for driving the vacuum pump, and a power supply for supplying electrical power to a plurality of components including the actuator, and also to a method for use in such as system. An output voltage of the power supply is detected, and in response to the detected output voltage being less than a first threshold voltage, the supply of electrical power to a predetermined one of the plurality of components is suspended. Then, if the detected output voltage recovers to a level above a second threshold value, the supply of electrical power is resumed.
