  • Optoelectronic switch having a photovoltaic response and associated method of use
    Patent number: 9455365
    Abstract: A light-induced diode-like response in multi-layered MoSe2 field-effect transistors resulting from a difference in the size of the Schottky barriers between drain and source contacts, wherein each barrier can be modeled as a Schottky diode but with opposite senses of current rectification, wherein the diode response results from the light induced promotion of photo-generated carriers across the smaller barrier. The sense of current rectification can be controlled by the gate voltage which is able to modulate the relative amplitude between both barriers, yielding a photovoltaic response.

  • System and method for leakage current suppression in a photovoltaic cascaded multilevel inverter
    Patent number: 9455645
    Abstract: The cascaded multilevel inverter is considered to be a promising topology alternative for low-cost and high-efficiency photovoltaic (PV) systems. However, the leakage current issue, resulting from the stray capacitances between the PV panels and the earth, remains a challenge in the photovoltaic cascaded multilevel inverter application. The present invention presents leakage current suppression solutions for the PV cascaded multilevel inverter by introducing properly arranged and designed passive filters. The embodiments of the invention do not include an active semiconductor device, and as such, the leakage current suppression techniques of the present invention retain the simple structure of the cascaded inverter and do not complicate the associated control system.

  • Probabilistic password cracking system
    Patent number: 9438419
    Abstract: System and methodology that utilizes keyboard patterns and alpha string patterns for password cracking. Keyboard patterns can be used as components of passwords, and the relevant shapes can extracted from these keyboard patterns and passwords. This keyboard information can be used to extend a probabilistic context-free grammar that can then be used to generate guesses containing keyboard patterns. Further, patterns in alpha strings, such as repeated words and multi-words, can be systematically learned using a training dictionary. This information can be used to extend the probabilistic context-free grammars which leads to generation of guesses based on the distribution of these patterns in the alpha strings, Keyboard patterns and alpha string patterns, individually and in combination, are shown herein to be effective for password cracking.
