  • Publication number: 20040098434
    Abstract: Non-binary methods of computing utilizing a digital multistate phase change material. Addition, subtraction, multiplication, and division are accomplished with the controlled application of energy to a phase change material. In one embodiment, energy in an amount insufficient to set the reset state of a phase change material is provided to store one or more numbers and further energy characteristic of the performance of a mathematical operation is provided to effect a computation. The set energy of the reset state of a phase change material provides an interval of energy that may be used to define programming states along the high resistance portion of the electrical resistance response curve of a phase change material. By sub-dividing this interval of energy, a plurality of programming states can be defined which are distinguishable in energy relative to the reset state.

  • Patent number: 6726783
    Abstract: A fundamentally new magnesium-based hydrogen storage alloy material which makes it feasible and practical to use solid state storage and delivery of hydrogen to power internal combustion engine or fuel cell vehicles. These alloys have remarkable hydrogen storage capacity of well over 6 weight percent. The alloys also have extraordinary absorption kinetics such that the alloy absorbs 80 percent of its total capacity within five minutes. The alloys are in particle form where the particles have a size ranging from 30 to 70 microns. The alloys also have a dual phase structure (formed by cooling from the melt at a cooling rate of 103-104° C.). The dual phase structure is such that an intergranular region surrounds a major hydrogen storage phase thus providing the alloys with resistance to sintering during high temperature hydriding/dehydriding cycling thereof. As a result of the dual phase structure, the alloys have an extended cycle life.

  • Publication number: 20040078415
    Abstract: A method of factoring numbers in a non-binary computation scheme and more particularly, a method of factoring numbers utilizing a digital multistate phase change material. The method includes providing energy in an amount characteristic of the number to be factored to a phase change material programmed according to a potential factor of the number. The programming strategy provides for the setting of the phase change material once for each time a multiple of a potential factor is present in the number to be factored. By counting the number of multiples and assessing the state of the phase change material upon execution of the method, a determination of whether a potential factor is indeed a factor may be made. A given volume of phase change material may be reprogrammed for different factors or separate volumes of phase change material may be employed for different factors.
