Abstract:
1. A method for recording and transmitting data between a transmission unit having a first antenna and a measurement module having at least one sensor for measuring variables, including biological variables, and transforms the measured variables into electrical signals and a measuring amplifier coupled to the sensor, which comprises the steps of: performing a bidirectional transmission of the data between the measurement module and the transmission unit, disposed in a near range of the measurement module, using a second antenna situated on the measurement module; transforming, via a reception unit coupled to the second antenna, electromagnetic energy of a signal present at the second antenna to electrical energy; intermediately storing the electrical energy, outputting the stored electrical energy in a form of a voltage level at an output of the reception unit, and delivering the stored electrical energy as a current to the sensor and the measuring amplifier; controlling components of the measuring module via a central data processing unit of the measurement module, while being supplied with the electrical energy stored in the reception unit, the central data processing unit further processing the measured variables of the sensor and communicating with the transmission unit; setting the first antenna of the transmission unit to be inactive for a time period of a determination of the measured variables by the sensor; and effecting the setting to inactive at an instigation of the measurement module, which signals to the transmission unit that a storing unit, connected to the reception unit, is fully charged and further signals from the transmission unit should be stopped; and which further comprises: a) setting the first antenna to be active for transmitting the electromagnetic energy to the reception unit, transmitting the electromagnetic energy between the first antenna and the second antenna, and storing the electrical energy in the measurement module; b) after transmission of a predetermined amount of the electromagnetic energy, transmitting or transferring a control pulse, generated by the measurement module, to the transmission unit, by which the first antenna is set inactive for a predetermined time period; c) during the predetermined time period, effecting a measurement of the measured variables to be determined; d) after the end of the predetermined time period, setting the first antenna of the transmission unit to be active again; and e) after an end of the measurement of the measured variables, transmitting the measured variables in coded form from the measurement module to the transmission unit; and f) carrying out steps a) to e) for a predetermined number of repetitions for carrying out a series of measurements of variables.
