Teleoperated Communication Robot: A Law Enforcement Perspective

Roya Salehzadeh, Fareed Bordbar, Xiaoti Fan, Soroush Korivand et autres

The goal of this article is to investigate the use of communication robots as tools to increase the safety of first responders (specifically, law enforcement officers (LEOs)) during social interactions or first-response situations. This article functions as the first stage of our …

Patients treated with vitamin K oral anticoagulants in family practice: a new approach to bleeding risk assessment. An ancillary study by the CACAO prospective general practice cohort

Yoann Gaboreau, Paul Frappé, Céline Vermorel, Alison Foote et autres

BACKGROUND: The ability of bleeding risk scores to predict major bleeding (MB) or clinically relevant nonmajor bleeding (CRNMB) remains a topic of contention, particularly in nonselected patients in family practice. In addition, the capacity to predict bleeding risk using simple variables has …

Exploring law enforcement officers’ expectations and attitudes about communication robots in police work

Xiaoti Fan, Roya Salehzadeh, Soroush Korivand, Fareed Bordbar et autres

This study explores the perspectives of law enforcement officers (LEOs) on the implementation of communication robots in police work. Through two approaches - open-ended questionnaires (N = 37) and focus group discussions (N = 14) - the research aims to gather LEOs' …

Oral anticoagulant safety in family practice: prognostic accuracy of Bleeding Risk Scores (from the CACAO study)

Yoann Gaboreau, Paul Frappé, Céline Vermorel, Alison Foote et autres

BACKGROUND: To assess bleeding risk of patients treated by oral anticoagulants, several scores have been constructed to assist physicians in the evaluation of the benefit risk. Most of these scores lack a strong enough level of evidence for use in family practice. …

Nonlinear Temperature Control of Additive Friction Stir Deposition Evaluated on an Echo State Network

Glen R. Merritt, Christian A. Cousin, Hwan‐Sik Yoon

Abstract Additive friction stir deposition is a recent innovation in additive manufacturing allowing the deposition of metallic alloys onto a metallic deposit bed, creating a purely mechanical metallic bond. The deposition can be done in a layer-by-layer manner, and the purely mechanical …

Dual Neural Network Control of a Hybrid Functional Electrical Stimulation Cycling System

Glen R. Merritt, Saiedeh Akbari, Christian A. Cousin, Hwan‐Sik Yoon

Abstract Hybrid functional electrical stimulation (FES) cycling is a method to rehabilitate people with neurological conditions when they are not in and of themselves capable of fully controlling their extremities. To ensure smooth cycling and adequate stimulation to accomplish the rehabilitation task, …

Public Perception, Privacy, Safety, and Ethical Considerations of Communication Robots in Law Enforcement

Roya Salehzadeh, Fareed Bordbar, Darrin J. Griffin, Christian A. Cousin et autres

To assist and protect citizen communities and police officers, robots have been developed for situational responses (e.g., explosive ordinance disposal). However, the robots used by law enforcement are typically expensive, can be difficult to operate, and do not readily facilitate communication between …

Closed-Loop Temperature and Force Control of Additive Friction Stir Deposition

Glen R. Merritt, Malcolm Brady Williams, Paul Allison, James Brian Jordon et autres

Additive Friction Stir Deposition (AFSD) is a recent innovation in non-beam-based metal additive manufacturing that achieves layer-by-layer deposition while avoiding the solid-to-liquid phase transformation. AFSD presents numerous benefits over other forms of fusion-based additive manufacturing, such as high-strength mechanical bonding, joining of …

Saturated Adaptive Control of Antagonistic Muscles on an Upper-Limb Hybrid Exoskeleton

Jace B. Aldrich, Christian A. Cousin

Functional electrical stimulation (FES) is a viable rehabilitation method for individuals affected by neurological injuries. When FES is combined with a powered exoskeleton, a hybrid exoskeleton is created. To control hybrid exoskeletons, a user’s muscles must be stimulated while simultaneously activating the …

Integral Concurrent Learning for Admittance Control of a Hybrid Exoskeleton

Glen R. Merritt, Saiedeh Akbari, Christian A. Cousin

Hybrid exoskeletons are a technology used by people with neurological injuries (e.g., spinal cord injury) for rehabilitation. Hybrid exoskeletons are a hallmark example of physical human-robot interaction because they combine functional electrical stimulation (FES) with a powered exoskeleton. Due to the physical …

A Hybrid Systems Approach to Dual-Objective Functional Electrical Stimulation Cycling

Saiedeh Akbari, Glen R. Merritt, Federico M. Zegers, Christian A. Cousin

Motorized functional electrical stimulation (FES) cycling can serve as a physical rehabilitation strategy for individuals whose lower limbs are affected by neurological injuries. Motorized FES cycling is unique among human-robot interaction tasks because the cycle’s motor and rider’s leg muscles must be …
