Modular origami shape-morphing soft exoskeletal legged robot
Patent published on the 2025-03-06 in WO under Ref WO2025050021 by THE REGENTS OF THE UNIV OF COLORADO A BODY CORPORATE [US] (Jayaram Kaushik [us], Kabutz Heiko [us])
Abstract: A body compliant quadrupedal micro-robot with four independently actuated leg modules, each having two degrees-of-freedom driven by piezoelectric actuators. The legs are interconnected in a closed kinematic chain via passive body joints enabling passive body compliance and passive adaptation to external constraints. The robot has multiple capabilities including omnidirectionality and confined terrain locomotion. The robot has an unconstrained top speed of approximately three body lengths per sec[...]

Adaptive fault prediction
Patent published on the 2025-03-06 in WO under Ref WO2025049459 by THE REGENTS OF THE UNIV OF MICHIGAN [US] (Toothman Maxwell [us], Moyne James [us], Tilbury Dawn [us], Barton Kira [us])
Abstract: A state-based framework is the basis for a methodology for predicting faults in industrial equipment or processes during multi-stage degradation. The methodology is based on an object-oriented scheme that allows system experts to identify signal trajectory classes that may occur during degradation. The methodology uses recent observations of a signal feature (x) to estimate the current health stage of a system and extrapolates signal trajectories forward in time to obtain probabilistic fault tim[...]
Our summary: Adaptive fault prediction methodology based on a state-based framework and object-oriented scheme allows system experts to identify signal trajectory classes during degradation, estimate system health stage using recent observations, and extrapolate signal trajectories for probabilistic fault time estimates. The framework incorporates subject matter expertise, reducing the need for historical training data and includes an anomaly detection sub-process for identifying deviations in signal trends.

Unified boundary machine learning model for autonomous vehicles
Patent published on the 2025-03-06 in WO under Ref WO2025048871 by AURORA OPERATIONS INC [US] (Chaabane Mohamed [us], Kaplan Benjamin [us], Litvin Yevgeni [us], O'hara Stephen [us], Vig Sean [us])
Abstract: A unified boundary machine learning model is capable of processing perception data received from various types of perception sensors on an autonomous vehicle to generate perceived boundaries of various semantic boundary types. Such perceived boundaries may then be used, for example, to control the autonomous vehicle, e.g., by generating a trajectory therefor. In some instances, the various semantic boundary types detectable by a unified boundary machine learning model may include at least a virt[...]
