Abstract:
There is provided a bed exit monitoring apparatus for monitoring a user and determining when the user has got out of a bed, the apparatus comprising a processor that is configured to receive measurements of the acceleration in three dimensions acting on a device that is attached to the user; and process the measurements to determine if the user has got out of bed.
Abstract:
For secure configuration of network nodes from a backend with low connectivity requirements and workload at the backend and reduced communication overhead, a system, a control unit for a segment controller and a method for secure protocol execution in a network are provided, wherein protocol information is provided to a segment controller (60) for controlling a node (10) and a protocol is performed based on the protocol information to control the node (10), at least one response message of the node (10) being required at the segment controller (60) for performing one or more steps of the protocol.
Abstract:
For a fine-grained flexible addressing of nodes in a wireless network with increased network scalability and transmission efficiency, a control unit, a node and a method is provided, wherein an addressee group of a plurality of destination nodes (11) is created by including at least one addressee condition in a multicast data packet for transmission of the multicast data packet.
Abstract:
The method for forwarding data packets in position based routing of data from a source node (S) to at least one destination node (D) of a mesh network (1) comprises the following steps. A data packet (2) originating from the source node (S) is received at an intermediate node (A) and the geographical position of the destination node (D) is obtained from the data packet (2). All accessible neighbor nodes (C i ) of the intermediate node (A) and their positions are determined. For each neighbor node (C i ) of the intermediate node (A), a deviation value (v i ) depending on the position of the neighbor node (C i ) in relation to a line of sight (4) between the intermediate node (A) and the destination node (D) is then determined and at least one of the neighbor nodes (C i ) is selected as a next intermediate node (B) depending on the determined deviation values (v i ). The data packed (2) is then forwarded to the selected next intermediate node (B).
Abstract:
The present invention relates to a transceiver device for processing a medium access control (MAC) protocol used by a transceiver. The transceiver has a first antenna system for on-body communications und a second antenna system for off -body communications, the transceiver device being designed to reserve one or more data payloads for on-body communications and to allocate the first antenna system to the transceiver for the interval of time occupied by these data payloads, and/or to reserve one or more data payloads for off -body communications and to allocate the second antenna system to the transceiver for the interval of time occupied by these data payloads. An advantageous result of this is that the optimally matched antenna system is available for on-body communications and off-body communications respectively, collisions between data payloads on the radio channel being prevented within the network, and the throughput of data thus being increased and, at the same time, energy consumption being reduced for the transceiver.
Abstract:
The invention relates to a network having at least one slave terminal (7-10) and a master terminal (6) that is connected thereto that is provided for instructing at least one slave terminal (7) to check for inquiries from at least one other terminal (11) to be incorporated in the network. The instructed slave terminal (7) following detection of an as yet non-incorporated terminal (11) forwards the received inquiry to the master terminal. Upon receipt of the inquiry from the slave terminal, the master terminal sets up a connection with the as yet non-incorporated terminal. In an embodiment, the master terminal (6) sets up the connection by emitting an inquiry and paging the new slave terminal (11).
Abstract:
In order to increase transmission reliability and transmission efficiency in the presence of interference at a transmitting or receiving node of a wireless network a device for controlling the node of the wireless network is provided, wherein the node is associated to at least one load unit. The device comprises a control unit that is adapted to adjust a communication mode of the node based on an operation state of the load unit.
Abstract:
For improving the protection of a network against denial of service attacks and other hostile attacks, while keeping the operation of the network simple and efficient and considering restricted capacities of single network nodes, a control unit, a system and a method for operating a network with a plurality of nodes are provided, wherein at least one operation parameter of at least one node is adjusted based on a current network phase and a data packet received by the node (10) is processed based on the operation parameter.
