AWARD Mitsubishi Electric US Receives a 2022 CES Innovation Award for Touchless Elevator Control Jointly Developed with MERL Date: November 17, 2021
Awarded to: Elevators and Escalators Division of Mitsubishi Electric US, Inc.
MERL Contacts: Daniel N. Nikovski; William S. Yerazunis
Research Areas: Data Analytics, Machine Learning, Signal ProcessingBrief- The Elevators and Escalators Division of Mitsubishi Electric US, Inc. has been recognized as a 2022 CES® Innovation Awards honoree for its new PureRide™ Touchless Control for elevators, jointly developed with MERL. Sponsored by the Consumer Technology Association (CTA), the CES Innovation Awards is the largest and most influential technology event in the world. PureRide™ Touchless Control provides a simple, no-touch product that enables users to call an elevator and designate a destination floor by placing a hand or finger over a sensor. MERL initiated the development of PureRide™ in the first weeks of the COVID-19 pandemic by proposing the use of infra-red sensors for operating elevator call buttons, and participated actively in its rapid implementation and commercialization, resulting in a first customer installation in October of 2020.

TALK [MERL Seminar Series 2025] Dick den Hertog presents talk titled Optimizing the Path Towards Plastic-Free Oceans Date & Time: Tuesday, March 11, 2025; 12:00 PM
Speaker: Dick den Hertog, University of Amsterdam
MERL Host: Arvind Raghunathan
Research Areas: Data Analytics, OptimizationAbstractIncreasing ocean plastic pollution is irreversibly harming ecosystems and human economic activities. We partner with a nonprofit organization and use optimization to help clean up oceans from plastic faster. Specifically, we optimize the route of their plastic collection system in the ocean to maximize the quantity of plastic collected over time. We formulate the problem as a longest path problem in a well-structured graph. However, because collection directly impacts future plastic density, the corresponding edge lengths are nonlinear polynomials. After analyzing the structural properties of the edge lengths, we propose a search-and-bound method, which leverages a relaxation of the problem solvable via dynamic programming and clustering, to efficiently find high-quality solutions (within 6% optimal in practice) and develop a tailored branch-and-bound strategy to solve it to provable optimality. On one year of ocean data, our optimization-based routing approach increases the quantity of plastic collected by more than 60% compared with the current routing strategy, hence speeding up the progress toward plastic-free oceans.

OR0180: Internship - System Identification
MERL is looking for a highly motivated and qualified PhD student in the areas of system identification, to participate in research on advanced algorithms for system identification of mechanical systems and processes. Solid background and hands-on experience with various system identification algorithms is required, including black-box and grey-box methods. Good understanding of mechanics is expected, as well as familiarity with algorithms for computing forward and inverse dynamics of mechanical systems. Of particular help would be expertise in tribology and metal-cutting technology. Hands-on experience with physics engines and other simulators would be a plus. Solid experimental skills and hands-on experience in coding in Python is required for the position. A more general understanding of machine learning algorithms, including deep learning, and experience with relevant libraries, such as scikit-learn and PyTorch would be considered a plus. Knowledge of time series analysis methods, in particular anomaly detection in time series, would also be beneficial. Hands-on skills in data acquisition from physical systems is desirable, but not strictly required.
The position will provide opportunities for exploring fundamental problems in system identification leading to publishable results. The duration of the internship is 3 to 5 months. Preference will be given to candidates who can start in the Fall of 2025 and no later than the beginning of January 2026.
