Inertial measurement units on micromechanical sensors
IEEE Aerospace and Electronic Systems Magazine, 2008This presents a micromechanical gyroscope (MMG), an inertial measurement unit (IMU)based on MMG and an integrated inertial-satellite attitude and navigation system (IANS) developed in CSRI Elektropribor. The evolution and prospects for the development of MMG main components and MMG-based systems is considered. The test results are given.

Measuring Arm Motions Using the Inertial Measurement Unit
2020 IEEE 2nd Global Conference on Life Sciences and Technologies (LifeTech), 2020This paper describes how to detect arm motions using Inertial measurement unit (IMU). The authors propose a method to attach the IMU to an upper arm and a lower arm as so to obtain the arm’s attitude information from the sensor’s data and thereby to detect the arm’s motions. Our experiment has shown that the arm’s flexion can be detected.

Calibration of an inertial measurement unit
2013 16th International Conference on Advanced Robotics (ICAR), 2013This paper presents a fast and low cost way to calibrate different inertial measurement sensors. In particular the calibration of an accelerometer and a gyroscope using nonlinear least squares is presented. A model of the sensors which includes the main errors that MEMS devices present is used. A calibration method is proposed for estimating the static

Low cost inertial measuring unit
IEEE PLANS 92 Position Location and Navigation Symposium Record, 2003A concept being explored is the use of an inexpensive IMU (inertial measuring unit) with the GPS (Global Positioning System). An inexpensive IMU can meet many of the same functional requirements as the high-accuracy system, with the exception of long-term position. For example, some applications for instrumenting a reference frame are antenna stability,

Morrison's QUBIK Inertial Measurement Unit
Navigation, 1988A new inertial system, “the QUBIK IMU,” uses a single sensor to provide all six output signals (three linear and three angular). The sensor is a cubic design with parallel orthogonal linear arrays of capacitors and magnetic suspension elements arranged on a selected plane for each axis of motion.

Respiration detection using Inertial Measurement Unit
2019 International Symposium on Electrical and Electronics Engineering (ISEE), 2019We propose a method to detect respiration using an inertial sensor. The inertial sensor attached to the chest or abdomen takes out the vector of the acceleration, angular velocity, and derives the quaternion from the Digital Measurements Processor function in the inertial sensor module, and detects respiration from time-series changes. We try to detect

Integrated Inertial Measurement Unit
2019With the more advanced pitch and roll gyroscope designs and microfabrication platform, achieving consistent high performance in all three axes using robust high-frequency resonant MEMS gyroscopes becomes possible. This chapter presents the first demonstration of a high-performance timing and inertial measurement unit (TIMU) with robust 3-axis resonant ...

Static and dynamic validation of inertial measurement units
Gait & Posture, 2017Optical motion capture systems are used to assess human motion. While these systems provide a reliable analysis, they limit collection to a laboratory based setting. Devices such as Inertial Measurement Units (IMUs) have been developed as alternative tools. Commercially available IMUs are utilized for a variety of applications; however limited work has

Foot-mounted inertial measurement unit for activity classification
2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014This paper proposes a classification technique for daily base activity recognition for human monitoring during physical therapy in home. The proposed method estimates the foot motion using single inertial measurement unit, then segments the motion into steps classify them by template-matching as walking, stairs up or stairs down steps. The results show

Load-embedded inertial measurement unit reveals lifting performance
Applied Ergonomics, 2018Manual lifting of loads arises in many occupations as well as in activities of daily living. Prior studies explore lifting biomechanics and conditions implicated in lifting-induced injuries through laboratory-based experimental methods. This study introduces a new measurement method using load-embedded inertial measurement units (IMUs) to evaluate ...
