Patent number: 11377734Abstract: A rational design and fabrication of ZnO/Al2O3 core-shell nanowire architectures with tunable geometries (length, spacing, branching) and surface chemistry is provided. The fabricated nanowires significantly delay or even prevent marine biofouling. In some embodiments, hydrophilic nanowires can reduce the fouling coverage by up to approximately 60% after 20 days compared to planar control surfaces. The mechanism of the fouling reduction is mainly due to two geometric effects: reduced effective settlement area and mechanical cell penetration. Further, superhydrophobic nanowires can completely prevent marine algal fouling for up to 22 days. Additionally, the developed nanowire surfaces are transparent across the visible spectrum, making them applicable to windows and oceanographic sensors.Type: GrantFiled: February 23, 2021Date of Patent: July 5, 2022Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Neil P.

Patent number: 11378399Abstract: A method for determining the rotational rate of a movable member using an array of inertial sensors is provided. The method includes defining a hidden Markov model (“HMM”). The HMM represents a discrete value measurement of the rotational rate of the movable member. A transition probability of the HMM accounts for a motion model (linear or non-linear) of the movable member. An observation probability of the HMM accounts for noise and bias of at least one of the inertial sensors of the array of inertial sensors. A processor receives input from the array of inertial sensors. The processor determines the rotational rate of the movable member by solving for an output of the HMM using the input received from the array of inertial sensors. The processor may use a forward algorithm, a forward-backward algorithm, or a Viterbi algorithm to solve the HMM.Type: GrantFiled: September 14, 2016Date of Patent: July 5, 2022Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: John Wang, Edwin Olson

Publication number: 20220188642Abstract: The lack of robustness of Deep Neural Networks (DNNs) against different types of attacks is problematic in adversarial environments. The long-standing and arguably most powerful natural defense system is the mammalian immune system, which has successfully defended the species against attacks by novel pathogens for millions of years. This disclosure proposes a Robust Adversarial Immune-inspired Learning System (RAILS) inspired by the mammalian immune system. The RAILS approach is demonstrated using adaptive immune system emulation to harden Deep k-Nearest Neighbor (DkNN) architectures against evasion attacks. Using evolutionary programming to simulate new B-cell generation that occurs in natural immune systems, e.g., B-cell flocking, clonal expansion, and affinity maturation, it is shown that the RAILS learning curve exhibits similar learning behavior as observed in in-vitro experiments on B-cell affinity maturation. The life-long learning mechanism allows RAILS to evolve and defend against diverse attacks.Type: ApplicationFiled: December 8, 2021Publication date: June 16, 2022Applicant: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Indika RAJAPAKSE, Alfred HERO, Alnawaz REHEMTULLA, Ren WANG, Stephen LINDSLY
