Abstract: A battery having a complete discharge mechanism includes a spring-biased switch with an element spring-biased from the switch and acts to close the switch when in a fully extended position. A block is position above the element with a passageway aligned with the element. A flexible positioned between the element and the passage prevents the element from extending into the passage. The tab extends through the battery casing. When pulled the tab allows the element to extend into the passage thereby closing the spring-biased switch and completing the discharge circuit.
Abstract: A semiconductor structure for providing an epitaxial zinc oxide layer having p-type conduction for semiconductor device manufacture and methods of depositing the p-type zinc oxide layer. A zinc oxide layer is deposited epitaxially by molecular beam epitaxy on a crystalline zinc oxide substrate. The zinc oxide layer incorporates a p-type dopant, such as nitrogen, in an atomic concentration adequate to provide p-type conduction. The p-type zinc oxide layer may further incorporate an atomic concentration of a compensating species, such as lithium, sufficient to electronically occupy excess donors therein so that the efficiency of the p-type dopant may be increased.

Abstract: An improved thermal battery with improved operating efficiency. The thermal battery utilizes both a first activatible heat source and a second independently activatible heat source. The second heat source is optionally activated under storage environment conditions, such as low temperature, which thereby allow battery operation of improved efficiency.
