  • Patent number: 5912839
    Abstract: Method of programming Ovonic memory multistate-digital multibit memory elements, and use thereof for neural networks and data storage. The device is programmed by applying an energy pulse which is insufficient to switch the memory element from said high resistance state to said low resistance state, but sufficient to modify said memory material such that accumulation of additional energy pulses causes the memory element to switch from said high resistance state to said low resistance state.

  • Patent number: 5856047
    Abstract: Nickel-metal hydride batteries and electrodes are capable of increased power output and recharge rates. The electrodes and batteries produced therefrom exhibit increased internal conductance. The positive and negative electrodes may be formed by pressing powdered metal-hydride active materials into porous metal substrates. The porous metal substrates are formed from copper, copper-plated nickel, or a copper-nickel alloy, and may be additionally plated with a material which is electrically conductive and resistant to corrosion in the battery environment, such as nickel.

  • Patent number: 5851698
    Abstract: Nickel-metal hydride batteries and electrodes capable of increased power output and recharge rates. The positive and negative electrodes may be formed by pressing powdered metal-hydride active materials into porous metal substrates. The porous metal substrates are formed from copper, copper-plated nickel, or a copper-nickel alloy. The electrode tab are directly attached to the porous metal substrate via a low electrical-resistance connection which includes welding, brazing, or soldering.
