Abstract: A monitoring device, including an encasement having an upper part and a lower part; wherein the lower part is attached by a hinge at a first side of the encasement to the upper part; wherein at an opposite side the upper part can be lowered onto the lower part to close the encasement or lifted up to open the encasement; an elongated strap with a first end and a second end wherein the first end of the strap is attached to the first side of the encasement and configured to enable coupling the monitoring device to a person by wrapping the strap around a limb of a person, and inserting the second end of the strap into the opposite side of the encasement onto the lower part and covering it with the upper part.

Abstract: Method for determining a distance between a first wireless transceiver of a first device and a second wireless transceiver of a second device, the method may include sending, by the first wireless transceiver and to the second wireless transceiver, (i) a first wideband message that consists essentially of a first synchronization preamble and (ii) a first narrowband message that may include first ranging information and does not include the first synchronization preamble; receiving, by the first wireless transceiver and from the second wireless transceiver, (i) a second wideband message that consists essentially of a second synchronization preamble and (ii) a second narrowband message that may include second ranging information and does not include the second synchronization preamble; and calculating, by the first device and based on portions of the first and second ranging information, a first estimate of the distance between the first wireless transceiver and the second wireless transceiver.

Abstract: A power line communication device includes a power line communication unit, a sensor to sense a physical connection to a second power line communication device other than via a powerline medium and a pairing unit to receive an indication of a physical connection between the power line communication device and the second power line communication device and to initiate a pairing process with the second power line communication device. A method of pairing communication devices which communicate along a non-data-cable medium includes sensing a data cable connection with a second device, entering an appropriate pairing state upon sensing the data cable connection, the pairing state being either an add device state or a join device state and performing pairing with the second device along the non-data-cable connection.
