In an example implementation, a sensor communication system includes a sensor to sense a condition and to include the condition in a message formatted in a communication protocol. The system includes a vibration actuator placed in contact with a building structure and operatively coupled to the sensor. The vibration actuator is to transmit the formatted message through the building structure as a vibration pattern, and an accelerometer is to detect the vibration pattern. A receiver hub coupled to the accelerometer is to decipher the condition from the vibration pattern.

The magnetic and electric field radiators are arranged to result in generation, by the antenna, of at least one of a transverse electric leaky wave and a transverse magnetic leaky wave in lossy body tissue of a human or animal body such that the lossy body tissue acts as a waveguide for the transverse electric leaky wave or transverse magnetic leaky wave, whereby to optimize at least one of the efficiency of the antenna and the far field gain of the antenna.

Devices and methods for controlling the functionality of a pair of earbuds. The first earbud establishes a connection between the first earbud and an electronic device, searches for the second earbud of the pair of earbuds using Body Coupled Communication, BCC, and sends a signal from the first earbud to the electronic device including information defining whether the first earbud detected the second earbud during the search. The electronic device receives a signal from the at least one of the earbuds, the signal comprising information defining whether the earbud has detected the other earbud of the pair of earbuds using Body Coupled Communication, BCC, and sends a signal to the at least one earbud wherein the signal is controlled based on the received signal and includes information associated with controlling the functionality of the pair of earbuds.

An approach for interference mitigation/avoidance in a first wireless network, for example a Body Area Network (BAN), uses signals from other BANs to adjust data transmissions by the first network.

A wireless sensor device capable of constant operation without replacement of batteries. The wireless sensor device is equipped with a rechargeable battery and the battery is recharged wirelessly. Radio waves received at an antenna circuit are converted into electrical energy and stored in the battery. A sensor circuit operates with the electrical energy stored in the battery, and acquires information. Then, a signal containing the information acquired is converted into radio waves at the antenna circuit, whereby the information can be read out wirelessly.

A body-coupled communication apparatus (100) comprises a coupler arrangement (10) comprising a plurality of couplers (11,12,13) configured to couple signals (S) between the apparatus (100) and a body (200). Signal electronics (20) are configured to process and/or generate the signals depending on an operational mode (OT,OR,OW) of the apparatus. A routing network (40) is configured to provide variable routing of the signals (S) between the signal electronics (20) and the couplers (11,12,13) thereby providing a selection between distinct coupling modes (CT,CR,CW) of the coupler arrangement (10). A mode selector (30) is configured to switch the apparatus (100) between the operational modes (OT,OR,OW) and control the routing network (40) to select between the distinct coupling modes (CT,CR,CW) based on the operational mode (OT,OR,OW) of the apparatus.
