Abstract: The invention relates to a method for determining the quantity of a fluid in a container (B), having the steps: transmitting (S20s) a specified bit sequence via an HF signal to determine channel state information, wherein the signal is directed at the container (B) and wherein a quantity to be determined is located in the container (B), receiving (S20) a reflection or a transmission of the transmitted HF signal, evaluation of errors and/or error parameters, comparison of errors and/or error parameters with at least one training parameter.

Abstract: A medical system, usable for example in connection with a dialysis apparatus, may utilize radar waves for monitoring a patient, a medical area, or an object. The medical system includes at least one sending device for sending radar waves, and at least one receiving device for receiving reflected radar waves. The medical system further includes an evaluation unit for evaluating the reflected radar waves which have been received by the at least one receiving device, resulting in obtaining a result, and an output device for outputting the result or a signal based on the result.

Abstract: The invention relates to device (1) for measuring volumes of a liquid in a container (B) by means of measuring emitted high-frequency radiation, comprising control unit (C), a transmitter (TX), at least one first transmitting antenna (ANT_TX1) and at least one second transmitting antenna (ANT_TX2), at least one receiving antenna (ANT_RX1) and a receiver (RX), wherein the transmitter (TX) is configured to emit high-frequency radiation when in operation, wherein the first transmitting antenna (ANT_TX1) and the second transmitting antenna (ANT_TX2) are configured to emit high-frequency radiation during operation so that radiation can reach the container (B), wherein first receiving antenna (ANT_RX1) is configured to record high-frequency radiation reflected from the container (B), wherein the receiver (RX) is configured to take up the high-frequency radiation received by the receiving antenna (ANT_RX1), wherein the control unit (C) is configured to control the transmitters so that the transmitter (TX) emits high
