Abstract: The present invention relates to secure paring of electronically controlled devices configured to communicate with each other. A medical system is provided comprising a first unit and a second unit, the system comprising a first communication link allowing a first group of data types to be transmitted between the first unit and the second unit, and a second communication link allowing a second group of data types to be transmitted between the first unit and the second unit. Different properties of the communication links may be used to ensure that certain data, e.g. during pairing of the two devices, can be transmitted in a more controlled way whereas other data can be transmitted in a less controlled way.

Abstract: The present invention relates to secure paring of electronically controlled devices adapted to communicate with each other. Thus, a medical system is provided comprising a first unit and a second unit, the system comprising first means of communication allowing a first group of data types to be transmitted between the first unit and the second unit, and second means of communication allowing a second group of data types to be transmitted between the first unit and the second unit. In this way different properties of the two means of communication can be used to secure that certain data, e.g. during pairing of the two devices, can be transmitted in a more controlled way whereas other data can be transmitted in a less controlled way.

Abstract: The present invention relates to secure paring of electronically controlled devices adapted to communicate with each other. Thus, a medical system is provided comprising a first unit and a second unit, the system comprising first means of communication allowing a first group of data types to be transmitted between the first unit and the second unit, the first unit comprising an acoustic transducer having a transducer coil with a plurality of windings, the transducer coil serving as an antenna for wireless signals transmitted between the first and second units. In this way a “par-=asite” property of the acoustic transducer can be used, i.e. using the coil as a receiving means, thereby replacing a receiving structure, e.g. a separate receiver coil or an antenna, which would otherwise have to be provided, this reducing manufacturing costs.

Abstract: The present invention relates to an indicating device adapted to be used in a system comprising a drug delivery system in combination with an indicating device for conveniently providing a user of a portable drug delivery device with information in respect of the delivery process. The delivery device is adapted for delivering a drug from a reservoir into a body of a user in accordance with a delivery rate value or profile, and comprises means for providing data information to the indicating device. The indicating device comprises means for receiving and storing data information from the infusion device, as well as timer means, where processor means is adapted for calculating an estimated time-dependent value based upon the received data and time information, and associated with indication means such as a display for indicating a calculated value, this allowing the indicating device to provide updated information independently of the delivery device.
