Abstract: Provided herein are methods and systems of producing hydrogen using ammonia borane, which has a high hydrogen density while being stable and easily stored. Ammonia borane may be exothermically reacted with a strong oxidizer, such as a mixture of hydrogen peroxide and water. The reaction between ammonia borane and the strong oxidizer may occur spontaneously and may produce heat. Unreacted ammonia borane may be exposed to and thermally decomposed using the heat produced during the exothermic reaction between ammonia borane and the strong oxidizer. The heat may be retained by performing the reactions in a vessel or reactor including a material capable of retaining the heat. A high gravimetric hydrogen yield is obtained from the reaction of ammonia borane with hydrogen peroxide and the thermal decomposition of unreacted ammonia borane. Hydrogen production using the methods and systems may yield a high gravimetric hydrogen content of at least about 10%.

Abstract: In one embodiment, a substrate assembly includes a flat substrate having oppositely disposed planar surfaces and a conductor. The conductor is formed on at least one of the planar surfaces and defines a conductor plane. The structure further includes an oversized-in-diameter anti-pad formed through the substrate layer and the conductor layer. The anti-pad further includes a dielectric spacer formed substantially coplanar with the conductor plane.

Abstract: A method and system enables a fixed cellular terminal (FCT) to be automatically configured to accommodate landline phones of the country and/or landline network in which it is physically located. The FCT includes a memory and a data structure therein. The data structure includes instructions on how landline phones interface with Public Switched Telephone Networks (PSTNs). Consequently, the FCT may be connected to a landline phone in any country and/or landline network once the FCT is informed of the country and/or landline network in which it is being used. According to one embodiment, a Subscriber Identity Module (SIM), which is needed to activate cellular phones in some systems, is used to inform the FCT of the country and/or landline network.

Abstract: A method and apparatus to set up a call between at least one standard analog terminal and a remote terminal, via a radio terminal or access a remote terminal or request a service in the network, via a radio terminal, while the radio terminal is engaged in a conversation with another remote terminal in the network.
