Abstract:
Methods, systems and devices for tracking and handling broadcast devices associated with luggage. A wireless identity transmitter within luggage may periodically transmit wireless broadcast messages that include obscured identifiers. When within proximity, a proximity broadcast receiver, such as a stationary device within an airport, may receive and relay the broadcast messages to a server which may process the included information. Based on decrypting the obscured identifiers, the central server may determine proximity information of devices related to the relayed messages. The proximity broadcast receiver may transmit messages based on whether the wireless identity transmitter should be handled via a luggage service. Additionally, the wireless identity transmitter may activate/deactivate an operational mode for use in an aircraft in response to receiving disable and enable wireless signals from proximate signaling transmitters. After receiving a disable wireless signal, the wireless identity transmitter may not transmit wireless signals until receiving an enable wireless signal.
Abstract:
A combination battery and antenna includes a battery having a positive contact and a negative contact, at least one of the positive contact and the negative contact comprising an antenna coupled to a matching circuit and to a radio frequency choke, whereby direct current (DC) is supplied to a battery circuit and a radio frequency (RF) signal is supplied to an RF circuit, and at least one secondary radiator parasitically coupled to the at least one of the positive contact and the negative contact of the battery.
