Measuring Acceleration Due to Gravity01:12

Measuring Acceleration Due to Gravity

1.4K
Consider a coffee mug hanging on a hook in a pantry. If the mug gets knocked, it oscillates back and forth like a pendulum until the oscillations die out.
A simple pendulum can be described as a point mass and a string. Meanwhile, a physical pendulum is any object whose oscillations are similar to a simple pendulum, but cannot be modeled as a point mass on a string because its mass is distributed over a larger area. The behavior of a physical pendulum can be modeled using the principles of...

Gyroscope01:02

Gyroscope

3.6K
A gyroscope is defined as a spinning disk in which the axis of rotation is free to assume any orientation. When spinning, the orientation of the spin axis is unaffected by the orientation of the body that encloses it. The body or vehicle enclosing the gyroscope can be moved from place to place, while the orientation of the spin axis remains the same. This makes gyroscopes very useful in navigation, especially where magnetic compasses cannot be used, such as in crewed and crewless spacecraft,...

Relative Motion Analysis - Acceleration01:10

Relative Motion Analysis - Acceleration

1.1K
A slider-crank mechanism converts rotational motion from the crank into linear motion of the slider or vice versa. This mechanism consists of three main parts: the crank, the connecting rod, and the slider. The movement of the slider-crank is an example of general plane motion as the fluctuating angle between the crank and the connecting rod. Consider a segment AB where point A is at the end of the slider and point B is on the diametrically opposite end to point A, on a crack. The variance in...

Relative Motion Analysis using Rotating Axes - Acceleration

1.0K
Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame. The absolute velocity of point B is determined by adding the absolute velocity of point A, the relative velocity of point B in the rotating frame, and the effects caused by the angular velocity within the rotating frame.
Time differentiation is...

Pulse Oximetry01:24

Pulse Oximetry

1.6K
Pulse oximetry, or SpO2, is a non-invasive method for continuously monitoring arterial oxygen saturation (SaO2). This procedure involves attaching a probe or sensor to the patient's fingertip, forehead, earlobe, or nose bridge. The sensor works by detecting changes in oxygen saturation levels through light signals generated by the oximeter and reflected by the pulsing blood under the probe.
Purpose
Average SpO2 values are greater than 95%. If the readings fall below 90%, it indicates that...

Pulse Assessment Sites01:11

Pulse Assessment Sites

3.5K
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

Area of Science:

  • Biomedical Engineering
  • Kinesiology
  • Wearable Technology

Background:

  • The activPAL accelerometer is widely used for physical activity assessment.
  • Direct skin attachment can cause skin irritation, necessitating alternative methods.

Purpose of the Study:

  • To validate the use of an elasticised pouch for securing the activPAL3c accelerometer.
  • To assess sedentary and physical activity behaviors using this alternative attachment method.

Main Methods:

  • Twenty-eight adults wore two activPAL3c accelerometers: one in a pouch, one skin-mounted.
  • Data collected during laboratory walking (various speeds) and free-living conditions.
  • Paired t-tests and intraclass correlation coefficients analyzed differences and agreement.

Main Results:

  • No significant difference in step count between pouch and skin-mounted devices during laboratory walking.
  • No significant difference in step count, upright time, sitting time, or postural transitions during free-living conditions.
  • High to very high agreement between the two attachment methods for all variables.

Conclusions:

  • An elasticised pouch is a valid method for attaching the activPAL3c accelerometer.
  • This method offers a potential advantage over direct skin mounting by mitigating skin irritation.
