Abstract: A transmitter 110 physically comprises a (local) sensor 120, normally located within a transmitter casing 130, for sensing a first parameter, a data transmission unit 140 for providing a wireless transmission to a receiver 150 of the telemetry system 100, and a coupling unit 170 for coupling one or more remote sensors 200i to the transmitter. While the transmitter is designed to transmit signals from the local sensor, it also allows to further or alternatively transmit signals from one or more remote sensors coupled to the coupling unit. This allows changing monitoring from one parameter to another parameter by simply coupling another remote sensor to the coupling unit.

Abstract: A telemetry system comprising a transmitter for transmitting signals, preferably electromagnetic signals, and a receiver for receiving the signals from the transmitter. The receiver comprises a receiver contact unit for providing a contact with a transmitter contact unit of the transmitter. The receiver contact unit and the transmitter contact unit are adapted to provide a data communication during a contact phase for assigning a transmission channel to the transmitter and/or to the receiver. The receiver may further include apparatus for monitoring a transmission activity in a pregiven channel range for determining possible channels in use, so that the transmission channel is assigned to the transmitter in accordance with the determined channels in use. The telemetry system according the invention is preferably used to for medical applications, such as pulsoximetry or electrocardiography.
