Abstract: A mesh network comprising an originator station and a target station wherein each station comprises a controller and memory for storing a first path table for storing one or more paths to be used for sending data packets and a second path table for storing one or more alternative paths for sending data packets. The originator station is configured to broadcast a path request data packet for the target station and receive a first path reply data packet comprising a first alternative path to the target station. Then the originator station is further configured to store the first alternative path in the second path table of the originator station and receive at least one second path reply data packet comprising at least one second alternative path to the target station.

Abstract: An arrangement of a mesh network comprising a first station, a second station and one or more intermediate stations is disclosed. The first, second and one or more intermediate stations are configured to comprise a sleep mode wherein the first, second and one or more intermediate stations are idle, and an awake mode wherein the first, second and one or more intermediate stations are awake. The first, second and one or more intermediate stations are further configured to be in the awake mode during a duration of a discovery window—DW—and a mesh management window—MMW—and wherein first, second and one or more intermediate stations are configured to listen for a synchronization beacon during the DW and to transmit and/or listen for zero or more mesh path hybrid wireless mesh protocol—HWMP—frames during the MMW.

Abstract: A method for a mesh network is disclosed. The mesh network comprises a first station, a second station and one or more intermediate stations. The communication within the mesh network is transmitted on a plurality of communication channels. The method comprises initiating a communication by the first station with the second station of the mesh network. The first station, the second station and the one or more intermediate stations together define a mesh path for the communication. The method also comprises defining by the first station a quality of service—QoS—class which indicates a desired level of quality of the communication. The method continues with determining available communication channels out of the plurality of communication channels based on the QoS and setting by the first station a limited number of mesh awake windows—MAW—as available for each available communication channel based on the QoS class.

Abstract: There is disclosed a device which inhibits the growth of microorganisms on the surface of a primary sensor element, such as the oxygen permeable membrane of a dissolved oxygen cell or the electrode and junction surfaces of a pH cell, immersed in an aqueous culture of the microorganism. The device includes a source of an antiseptic or disinfectant having a slow aqueous dissolution rate that is supported by a carrier having a transport system to sweep the source across the surface to be protected and a drive system to actuate the transport mechanism in a repetitious or a cyclic fashion. In the preferred embodiment the antiseptic source is a copper or heavy metal plate on the end of a blade that is reciprocated across the exposed membrane surface of a dissolved oxygen cell by a spring biased electrical vibrator.
