A Visual Analytic in Deep Learning Approach to Eye Movement for Human-Machine Interaction Based on Inertia Measurement

open access: yesIEEE Access, 2020
This paper proposes a hand free human-machine interaction (HMI) system to establish a novel way for communication between humans and computers. A regular interaction system based on the computer mouse puts the user's hand for too long in a pronation ...

On power-complementary FIR filters [PDF]

open access: yesIEEE Transactions on Circuits and Systems, 1985
Conditions are derived, under which two linear-phase FIR filter transfer functions H(z) and G(z) have the power-complementary property, i.e., |H(e^{j \omega})|^{2} + |G(e^{j\omega})|^{2} = 1 . It is shown that, the constraint of linear phase on the transfer functions strongly restricts the class of frequency responses that can be realized by a power ...

Velocity-Aided Attitude Estimation for Helicopter Aircraft Using Microelectromechanical System Inertial-Measurement Units

open access: yesSensors, 2016
This paper presents an algorithm for velocity-aided attitude estimation for helicopter aircraft using a microelectromechanical system inertial-measurement unit. In general, high- performance gyroscopes are used for estimating the attitude of a helicopter,

Complementary filter synthesis of gyrostabilizer

open access: yesInformation systems, mechanics and control, 2018
This paper considers the synthesis of a complementary filter designed to determine the angular position of the gyrostabilizer platform. An engineering synthesis technique is proposed, allowing you to select filter parameters and evaluate its effectiveness. The question of the synthesis of a complementary filter in the platform is considered.

How Magnetic Disturbance Influences the Attitude and Heading in Magnetic and Inertial Sensor-Based Orientation Estimation

open access: yesSensors, 2017
With the advancements in micro-electromechanical systems (MEMS) technologies, magnetic and inertial sensors are becoming more and more accurate, lightweight, smaller in size as well as low-cost, which in turn boosts their applications in human movement ...

Extension of the Rigid-Constraint Method for the Heuristic Suboptimal Parameter Tuning to Ten Sensor Fusion Algorithms Using Inertial and Magnetic Sensing

open access: yesSensors, 2021
The orientation of a magneto-inertial measurement unit can be estimated using a sensor fusion algorithm (SFA). However, orientation accuracy is greatly affected by the choice of the SFA parameter values which represents one of the most critical steps.

Design of self-monitoring sensor for position and orientation of equipment in coal mine

open access: yesMeikuang Anquan, 2022
Aiming at the problem that the performance of key equipment in underground coal mine is degraded and the function is lost to lead to a safety accident eventually due to the deviation of the installation position and orientation or the artificial movement

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

Application of Filters to Improve Flight Stability of Rotary Unmanned Aerial Objects

open access: yesSensors, 2022
The most common filters used to determine the angular position of quadrotors are the Kalman filter and the complementary filter. The problem of angular position estimation consist is a result of the absence of direct data.

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.
