Online Calibration of Inertial Sensors Based on Error Backpropagation.
Sensors (Basel)

Global satellite navigation systems (GNSSs) are the most-used technology for the localization of vehicles in the outdoor environment, but in the case of a densely built-up area or during passage through a tunnel, the satellite signal is not available or has poor quality. Inertial navigation systems (INSs) allow localization dead reckoning, but they have an integration error that grows over time. Inexpensive inertial measurement units (IMUs) are subject to thermal-dependent error and must be calibrated almost continuously.

- The study explores the role of SMARCA5 (SNF2H) in the development of hematopoietic cells, highlighting its importance for proper embryonic and organ development in mice.
- Mouse models show that a reduced expression (hypomorphic allele) of SMARCA5 can rescue defects in hematopoiesis and lethality caused by its complete deletion in specific hematopoietic progenitor cells.
- Results indicate that while low SMARCA5 levels allow normal embryonic development, they disrupt lymphoid lineage entry and differentiation in hematopoietic stem cells, whereas myeloid lineage development remains largely unaffected.
The article deals with sensor fusion and real-time calibration in a homogeneous inertial sensor array. The proposed method allows for both estimating the sensors' calibration constants (i.e.

- The review examines various driving mechanisms and sensors for spherical robots, highlighting their holonomic nature and protective shells that safeguard internal components.
- It identifies the limitations of typical sensors in these robots while proposing the addition of advanced sensors like cameras and LiDARs to enhance environmental sensing abilities.
- The paper suggests that by integrating these enhanced sensors, spherical robots can be effectively designed for specialized underground exploration tasks, such as responding to accidents in mines or road tunnels.
Occasionally intubation of patients is difficult using a video laryngoscope (GlideScope, Verathon Medical) because of an inability to guide the endotracheal tube to the glottis or pass the tube into the trachea despite an adequate view of the glottis. We examined methods to improve success when this difficulty occurs. A literature search revealed 253 potential sources, with 25 meeting search criteria: 7 randomized controlled trials, 4 descriptive studies, 8 case series, and 6 case reports.
