Abstract: A headset for audio play, comprising one or more sensor circuit and a control module. The control module comprises a secondary processor circuit and a primary processor circuit. The sensor circuit generates sensor data according to structural deformations of the headset. The secondary processor circuit receives the sensor data and calculates measured values related to the structural deformations of the headset. The primary processor circuit coupled to the secondary processor circuit controls an audio play operation in the headset, and enters a sleep mode when the audio play operation is not required. The secondary processor circuit determines a usage status of the headset according to the measured value and one or more threshold value. The secondary processor circuit wakes the primary processor circuit according to the usage status, and adaptively adjusts at least one threshold value according to the usage status.

Abstract: A sonic ranging method for a mobile phone and a wireless earphone. Firstly, the mobile phone performs an acoustic response test on the wireless earphone. The mobile phone generates a first audio sequence at a first time slot. The wireless earphone recognizes the first audio sequence to generate a second audio sequence. When the mobile phone recognizes the second audio sequence, the mobile phone estimates a length of elapsed time according to the time difference between a current time slot and the first time slot. When the mobile phone obtains the length of elapsed time, a distance between the wireless earphone and the mobile phone may be determined according to a delay compensation parameter and the length of elapsed time. Various potential applications can be implemented based on the invention without the needs for additional hardware circuits in the mobile phone.

Abstract: A node device (4) in a network (1) of communicatively interconnected node devices (4) having limited data processing and storage resources, such as a mesh network (1) of node devices (4), receives an inquiry message of the type ‘find the best match’ for information to be located at a node device (4). The inquiry message comprises benchmark data relating to the information to be located. The receiving node device updates the message based on a comparison of the content in the latest received message and the node's locally stored information. The locally stored information is derived from previous received messages from other node devices (4) in the network (1) and information available at the receiving node device. When no update is required, no message is broadcasted by a node device (4) and the local copy at the node devices involved converges in a few broadcasts to a static content from which the information sought can be located in the network (1).

The mesh network bridging device is operable over both a first communication channel, so as to communicate with the resource restricted device, and a second communication channel, so as to communicate with the mesh network. The mesh network bridging device is adapted to switch between a first and second mode of operation, associated with the first and second communication channel respectively, so as to alternately communicate with the resource restricted device and the mesh network bridging device. The mesh network bridging device may thereby act as a bridge between the resource restricted device and the mesh network bridging device.

Abstract: 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.
