Abstract: Ultra low frequency transmissions can be used to penetrate obstructions to areas where other operation of other communication devices may be limited, such as in a mine, tunnel, or other underground location. A portable device that includes a supercapacitor, a transmitter, and an antenna can be used to communicate using ultra low frequency transmissions. In one aspect, a communication device comprises a supercapacitor; a transmitter powered by the supercapacitor; and an antenna connected to the transmitter for sending messages. In another aspect, a method for communicating comprises the steps of receiving a message to be transmitted, powering a transmitter from a charged supercapacitor, and transmitting the message via an antenna.

Abstract: An ultra low frequency transmission system can provide communications, for example, messages, to an individual or a group in areas of a building where conventional transmission reception is limited. A communication system for a structure includes a transmitter and an antenna network extending substantially throughout the structure. The antenna network includes a first portion and a second portion. At least one location in the structure can receive a transmission from the first portion and the second portion of the antenna network. The antenna network is configured to receive the transmission from the transmitter and to communicate the transmission throughout the antenna network to at least one receiver configured to receive the transmission from the transmitter via the antenna network. The antenna network transmits the transmission using an ultra low frequency to the at least one receiver.

Abstract: A method for securely executing a charge transaction establishes an encrypted communication link between the mobile telecommunication device and a host by utilizing executable program code in the mobile telecommunication device. The method transmits data related to a charge transaction request from the host to the mobile telecommunication device via the encrypted communication link, and further transmits a second of at least two in combination unique data sets from the mobile telecommunication device to the host via the encrypted communication link as authorization for the charge transaction to be executed, and even further transmits from the host to a payment service provider, data related to the charge transaction request, the received second data set and a, in combination with the received second data set unique first data set stored at the host. The method completes the charge transaction if the first and second data sets in combination authorize the charge transaction.
