  • Patent number: 10608587
    Abstract: A method and crystal oscillator circuit match a supply voltage with a drive level of a crystal. The crystal oscillator circuit is based on a Pierce oscillator circuit which further includes a capacitor Cd. The capacitor Cd together with the load capacitor act as a capacitive voltage divider and the capacitance of this capacitor may be selected to reduce the supply voltage to match the drive level of the crystal oscillator without affecting the oscillation margin of the crystal.

  • Patent number: 10555237
    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.

  • Patent number: 10027572
    Abstract: A station (100, 330) for use in a mesh network comprising at least one first station (100a) and a second station (100b) wherein the station comprises a controller (210) configured to receive a path request for a path from the first station (100a) to the second station (100b); determine a proposed path between the first station (100a) and the second station (100b); and determine a cost for the proposed path, wherein the controller (210) is characterized in that it is configured to retrieve a number of jumps and a bit rate, and to include the number of jumps and a bit rate in the determination of the cost for the proposed path, wherein an increase in number of jumps and/or decrease in bit rate leads to an increase in cost for the proposed path.

  • Patent number: 9930604
    Abstract: A station (100, 330) for use in a mesh network comprising at least one first station (100a) and a second station (100b) wherein the station comprises a controller (210) configured to receive a path request for a path from the first station (100a) to the second station (100b) from a transmitting station (100a); determine a proposed path between the first station (100a) and the second station (100b); and determine a cost for the proposed path. The controller (210) is configured to retrieve a power output level for the transmitting station (100a), and to include the battery level in the determination of the cost for the proposed path, wherein an increase in power output level leads to an increase in cost for the proposed path.

  • Publication number: 20150172991
    Abstract: A network device comprising a memory, an interface and a controller for use in a mesh network comprising at least one second network device and at least one another or alternative network device. The network device is configured to be connected to said second network device. The controller of the network device is configured to receive a communication from a second network device or another or alternative network device through said interface and to monitor a signal strength that said communication was received at. The network device is configured to determine whether said connection is to be replaced based on said monitored signal strength and, if so, cause said connection to be replaced.
