Abstract: Physiologic monitor and monitoring method for calculating the risk that a dementia-affected patient wanders away from a predefined safe area. Skin conductivity or heart rate are used to predict the user's emotional state which could lead to a wandering event. If the risk level is high, an alarm is sent to the caretaker. False alarms are reduced by considering additional input information such as activity level of the person, location of the person, time of day.

Abstract: A device for transmitting in multiple coupling modes has a transmission module (11), at least one periphery module (18), and an antenna (16, 17) for each of the multiple coupling modes. Further, in a method of switching between multiple coupling modes, switching is conducted between at least polling and listening phases of first and second coupling modes.

Such a coupling or switching is particularly useful for performing secure transactions whereby through body coupled communication a body-worn tag is interrogated which provides a secure code for a transaction initiated through near field communication with a transaction terminal.

Abstract: When installing and maintaining a wireless sensor network in a medical or factory environment, distribution of keying material to sensor nodes (18) is performed by a key material box (KMB) (12), such as a smartcard or the like. The KMB (12) has a random seed stored to it during manufacture, and upon activation performs an authentication protocol with a sensor node (18) to be updated or installed. The KMB (12) receives node identification information, which is used in conjunction with the random seed to generate keying material for the node (18). The KMB (12) then encrypts the keying material for transmission to the node (18), and transmits over a wired or wireless communication link in a secure manner. The node (18) sends an acknowledgement message back the KMB (12), which then updates the nodes status in look-up tables stored in the KMB (12).

User authentication, access control and logging are performed based on identifying and authenticating the fingerprint.

Abstract: In a distributed revocation method, it is individually decided at each of a plurality of autonomous device nodes of a distributed network whether a suspect autonomous device node or suspect distributed key of the distributed network should be removed from the distributed network. A voting session is conducted at which the individual decisions of the plurality of autonomous device nodes are combined to decide whether the suspect autonomous device node or suspect distributed key should be removed from the distributed network. The suspect autonomous device node or suspect distributed key is removed from the distributed network responsive to the voting session deciding in favor of removal.
