A physiological measurement system comprises a digital module, which receives an analog bio-signal, a digital unit, which converts the at least one analog bio-signal into a digital signal form, and a first 5-pin-USB-connector, which output the bio-signal in the digital signal form. A bio-signal processing unit, which comprises a counter 5-pin-USB-connector, which is connected with the first 5-pin-USB-connector and receives the bio-signal from the digital module, and alternatively receives analog bio-signal in an analog signal form. The bio-signal processing unit distinguishes between the digital and analog signals and performs: an electric connection of the counter 5-pin-USB-connector with an input of an analog-to-digital converter circuit, an output of which is electrically connected with a digital data processing unit of the bio-signal processing unit, in response to detection of the analog signal received from the counter 5-pin-USB-connector, and an electric connection of the counter 5-pin-USB-connector with the digital data processing unit in response to detection of the digital signal received from the counter 5-pin-USB connector.

Physiological measurement system, bio-signal processing unit and method

A bio-signal measurement apparatus comprises tool-less connectors, coupling targets, a controllable coupling selection arrangement, and a control arrangement. The tool-less connectors are for an electric contact with a separate docking apparatus or an electrode arrangement. The coupling targets include a battery and a data communication unit that performs electrically a plug-and-play data transfer with the separate docking apparatus. The tool-less connectors, the number of which is three, are electrically coupled with the controllable coupling selection arrangement, which electrically couples all the tool-less connectors with only one of the coupling targets at a time in response to control from the control arrangement. The battery receives electricity from the tool-less connectors for charging the battery through the electric coupling caused by the coupling selection arrangement under control of the control arrangement during a first time window when the bio-signal measurement apparatus is connected with the docking apparatus. The data communication unit sends and/or receives data through the tool-less connectors using the plug-and-play data transfer based on the electric coupling caused by the coupling selection arrangement under control of the control arrangement during a second time window when the bio-signal measurement apparatus is connected with the docking apparatus.

Bio-signal measurement apparatus, docking apparatus and methods of their coupling

The present disclosure discloses an arrangement for measuring a biosignal. The arrangement has a sensor module and a control module. The sensor module has structure for sensing at least one biosignal and a first connector for interfacing with the control module. The control module has a first counterpart connector connected to the first connector of the sensor module, structure for processing biosignal data sensed with the sensor module, a storage memory for storing processed bio signal data, a rechargeable battery for providing operating power for the control module, structure for wirelessly transmitting the processed biosignal data to a computing device, such as a PC, a tablet PC or a smart phone, for post-processing, and a second connector for interfacing with a second electrode.
