Abstract: The invention relates to an assembly comprising a main device and an accessory, which can be connected by a safe connector and a safe detection method. According to the invention, the assembly comprises: —a main device (2), —an accessory (3) connectable to the main device (2), —the accessory (3) comprising an accessory connector (4) for mating with a device connector (5) of the main device (2), —the accessory connector (4) and the device connector (5) each comprising one or more supply contacts (7) for transmitting electric power from the main device (2) to the accessory (3), —the main device (2) comprising a detection device (9), which, if connecting the accessory (3) to the main device (2), receives complex accessory data stored by the accessory (3) and which by positive evaluation of the complex data enables applying a supply voltage at the one or more supply contacts (7) of the device connector (5).

Abstract: The present invention relates to a signal measurement system (100, 200, 300) for measuring a signal, the system comprising a signal detection unit (41) for detecting a raw signal, a signal processing unit (42) and a signal cable (10) electrically connecting the signal detection unit (41) with the signal processing unit (42). The signal cable (10) comprises a signal conductor (1, 2) for electrically conducting a first signal from the signal detection unit (41) to the signal processing unit (42), which first signal comprises at least the raw signal, a reference conductor (11, 12) for detecting and electrically conducting to the signal processing unit (42) only a noise signal induced by a movement of the signal cable (10) or by electromagnetic interference.

Abstract: The present invention relates to a method for operating a monitoring system for monitoring physiological data of a patient. For saving power, motion activity data of the patient is obtained and the measurement of physiological data of the patient is initiated, if the motion activity is non-zero and below a selected threshold.

Abstract: A method of recognizing at least one moving anatomical structure using ultrasound data that operates by receiving ultrasound data 100 (100). The ultrasound data comprises Doppler shift information which provides information descriptive of the velocity of at least one anatomical structure. The ultrasound data is first divided into a series of time frames (102). A classification is then assigned to each of the time frames using the Doppler shift information (104). The at least one anatomical structure is then recognized by using the classification of each time frame (106). This is possible, because different anatomical structures produce different patterns in the Doppler shift information.
