Summary: This study investigates the influence of sensor placement for cardiorespiratory monitoring using inertial measurement units (IMUs). Triaxial accelerometer data was collected from 15 healthy volunteers in different postures, and the most informative axis and sensor position were determined. The general-purpose configuration allows accurate estimation of respiratory rate (RR) and heart rate (HR), while the posture-dependent configuration improves RR estimation, especially during walking and standing.

Summary: Recent scientific and technological advances have led to the detection of gravitational waves, autonomous driving, and the proposal of a communications network on the Moon. These advancements are based on measuring minute displacements and transducing them into corresponding forces for navigation purposes. The use of laser optomechanical transduction and readout has allowed for highly sensitive detection of motional displacement. The article presents a theoretical framework and demonstrates physical agreement with the theory, and characterizes various performance parameters of the inertial accelerometer.

Summary: Individuals with HD exhibited larger APA acceleration amplitudes, smaller first step ROM, and longer first step durations during walking. Cognitive loading influenced first step ROM but not other APA parameters. The mediolateral APA acceleration amplitudes were a significant predictor of gait speed.

Summary: Advancements in micro-electromechanical systems technology have led to the development of miniature, low-power, and high-performance inertial motion sensors that are widely used in smart gadgets. These sensors have the potential to enable efficient home-based health monitoring, especially in the continuous monitoring of lower-limb joints on wearable platforms for tele-rehabilitation of patients with motor impairments. The proposed sensor fusion algorithm successfully estimates lower-limb joint angles in real-time, demonstrating robustness against external acceleration and magnetic disturbances.

Summary: In this paper, a LiDAR-inertial-GNSS fusion positioning algorithm based on voxelized accurate registration was proposed to address the insufficient accuracy and accumulated error of LiDAR-inertial odometry (LIO) point cloud registration in urban environments. The algorithm utilizes curvature segmentation for voxelized point cloud downsampling and constructs a point cloud registration model based on nearest neighbors. An iterative termination threshold is set to reduce local optimal solutions. The algorithm achieves more continuous and accurate position and attitude estimation and map reconstruction in urban environments.
