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 (Ci) of the intermediate node (A) and their positions are determined. For each neighbor node (Ci) of the intermediate node (A), a deviation value (vi) depending on the position of the neighbor node (Ci) 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 (Ci) is selected as a next intermediate node (B) depending on the determined deviation values (vi). The data packed (2) is then forwarded to the selected next intermediate node (B).

Abstract: A high percentage of preventable medical errors occur due to poor communication during the period when patient care is handed from one caregiver to another. Electronic annotations from patient specific body sensor networks are created and classified according to the caregiver and the urgency of the annotation to ensure that no information goes unnoticed during the transfer of care. Sensors (10) of each body sensor network store the annotations, and share the annotations with all the other sensors in the network. The sensors (10) communicate wirelessly with a monitor (12), nurses station (14) a portable device (16) or other device (19) associated with a medical facility network to display the annotations for the caregiver on an associated display (12a, 14a, 16a, 19a). The caregiver can view, create, edit, and delete annotations with input devices (12b, 14b, 16b, 19b) as appropriate.

Abstract: A patient monitoring system (8) monitors health related parameters of a patient (10). A medical device (12) obtains measurements of the health related parameters of the patient (10). A first mobile device (16), associated with the patient (10), wirelessly collects and transmits the health related parameters of the patient (10). A second mobile device (22), in operative communication with first mobile device, receives the transmitted health related parameters of the patient.

Abstract: The present invention relates to a method, a client device (CL) and a computer program product for determining the need for requesting network configuration information from a network. The client device includes memories (M1, M2) comprising network identifying data (NI) and corresponding configuration data, and a control unit (CO). The control unit orders the connection of the client device to a network, compares first network identifying data associated with said network with second locally stored network identifying data from a memory and uses locally stored network configuration data associated with said second network identifying data for obtaining services if said first network identifying data and said second network identifying data correspond to each other. Because of this the number of searches in a network is limited in case the client device has previous knowledge about the network.
