A self-balancing board is provided, comprising a primary wheel assembly, a platform, at least one sensor, a controller, a first auxiliary wheel assembly, and a first brake element. The primary wheel assembly comprises a primary wheel and a motor driving the primary wheel. The platform is secured to the primary wheel assembly and has a foot deck. The at least one sensor senses the orientation of the platform. The controller receives data from the at least one sensor and controls the motor in response to the received data. The first auxiliary wheel assembly is secured to the platform distal the primary wheel assembly, and is elevated from contacting a flat surface upon which the primary wheel rests when the foot deck is parallel to the flat surface. The first brake element is manually movable relative to the first auxiliary wheel assembly to engage the first auxiliary wheel assembly to provide resistance to rotation of the first auxiliary wheel assembly.

The invention relates to a method for transmitting information, particularly network parameters for connecting to a wireless network, from a provisioning device to a wireless device via a wireless interface. The information is obtained in an encoded form in the provisioning device and the provisioning device transmits a sequence of data packets () in accordance with a pattern generated based on the encoded information. Each element of the pattern correspond to a predetermined time distance between consecutive data packets () or to a predetermined data packet length, and the data packets () have a length which is smaller than a maximum length supported by the wireless interface.

A foot-deck-based vehicle includes a support structure having a longitudinal axis, a first foot-deck portion, and a second foot-deck portion. Each of the first foot-deck portion and the second foot-deck portion have a foot support surface. The foot support surfaces of the first and second foot-deck portions are positioned to support first and second feet of a rider respectively. The foot-deck-based vehicle further includes at least one wheel that is rotationally connected to the support structure for rotation about a lateral axis. The first and second foot-deck portions are movably connected at least indirectly to each other and are movable between a use position and a stowage position.

Compactable foot-deck-based vehicle

The present invention relates to a method for routing messages through a mesh network comprising a plurality of nodes, wherein a message is send from a sending node to a receiving node. The method comprises the steps of defining a routing table designating a path from a source node to a destination node through the mesh network, and defining a neighbor table listing one or more neighbor nodes from the plurality of nodes which are in the neighborhood of the sending node. If the destination node is not in the neighbor table of the sending node, the message is transmitted by the sending node to a receiving node adapted to forward the message to the destination node in accordance with the routing table. The one or more neighbor nodes save the message in internal storage and a predetermined number of helping nodes from the one or more neighbor nodes repeat the message after respective predetermined time intervals have passed, wherein the number of helping nodes being smaller or equal than the number of neighbor nodes.

A broadcast transmission will generate a packet storm in a mesh network, which will last for a very long time and block the network for other traffic. There is a parameter in a broadcast control mechanism named radius which controls the duration of the packet storm. The invention proposes to dynamically select the smallest radius to reduce the packet storm to a minimum, by reporting the smallest possible radius parameter for the broadcast control mechanism. Each device or node of the network comprises a neighbor table for tracking which of its neighboring devices or nodes has successfully relayed the broadcast transmission. Additionally, each device or node comprises a broadcast transaction table to keep a record of any new broadcast transmission or transaction that is either initiated locally or received from a neighboring device or node. Each broadcast transmission comprises a so called radius parameter R which indicates an allowed number of hops through the mesh network before the broadcast transmission is discarded. The mechanism to report broadcast status may be realized in an exemplary embodiment of the invention by adding two new tables to track broadcasting status from neighboring devices: the child table, to which the concerned network node or network device has transmitted or relayed a broadcast transmission, and the broadcast listening table; and by adding three fields into the broadcast transaction table: the radius, report interval and report timeout; and also by adding two new parameters into broadcast message itself: report interval and report timeout.

A mesh WLAN controller () operates in mesh soft-access-point or mesh client modes. When operating in the mesh client mode it performs a mesh network scan, for detecting at least one mesh WLAN BSS (), send mesh client access requests to mesh WLAN BSSs detected, and, if mesh client access is achieved, provide information indicative to the accessed WLAN BSSs of any other mesh WLAN BSS to which mesh client access is achieved, and if mesh client access is not achieved with any of the detected mesh WLAN BSSs, operate in the mesh soft-access-point mode. Upon receiving an instruction to operate in a mesh bridge-client mode, the controller detects messages from any of the mesh WLAN BSSs () with mesh client access, and forwards the received mesh WLAN messages within any other of the mesh WLAN BSSs to which mesh client access has been achieved.
