First Claim
1. A device comprising an electronic key comprising at least one wireless communication interface, the electronic key being operable as an access control key to unlock an electronic lock when the electronic key is placed in proximity of the electronic lock and the electronic lock has been configured to allow temporal access to the electronic key, the electronic key being also operable to perform at least two of the following additional functions:
- a) sense an electric field by an electric field sensor which is part of the electronic key, and process data obtained by sensing the electric field, and wirelessly send data obtained by the processing;
b) in response to activation of a switch that is part of the key, wirelessly communicate a distress signal to a recipient device operable, upon receipt of the distress signal, to determine a location of the electronic key by performing a measurement performed on a signal transmitted between the device and the electronic key;
c) sense the electronic key'"'"'s motion by a spatial motion sensor which is part of the electronic key, thereby obtaining data related to the electronic key'"'"'s acceleration and/or spatial orientation, and process data obtained by sensing the electronic key'"'"'s motion, and wirelessly send data obtained by the processing of data obtained by the sensing of the electronic key'"'"'s motion.

Abstract
A multifunction electronic key is provided with at least one wireless communication interface that can function as an access control key to unlock an electronic lock when the key is placed in proximity of an electronic lock that has been previously configured to allow temporal access to the said electronic key, and at least one of the following functions: a) Measure the electric field experienced by the device, process it and optionally send it to a second wireless device; b) A physical button to communicate a distress signal to a second wireless device, in response to which the second wireless device estimates the position of the electronic key and generates a system alarm indicating the identity of the electronic key that generated the alarm and its position estimate; c) Measures the device'"'"'s motion, process it and optionally send it to a second wireless device; d) One or two way audio communication via the wireless link; e) Measures ionizing radiation.
