Equipments Used to Measure Body Temperature01:13

Equipments Used to Measure Body Temperature

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Equipments Used To Measure Blood Pressure

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Purpose of the Study:

  • To develop and validate a cost-effective sports monitoring system using an inertial sensor.
  • To assess the real-time performance of an IMU in tracking key gait parameters.
  • To compare the efficacy of accelerometer and gyroscope data for gait analysis.

Main Methods:

  • An inertial sensor (IMU) was attached to the athlete's right leg.
  • The accelerometer measured leg angle during walking and running.
  • The gyroscope processed data to determine stride frequency and enabled time-to-frequency domain conversion.
  • The number of strides and linear velocity were calculated.
  • Statistical hypothesis testing was used to validate the results.

Main Results:

  • The IMU successfully tracked four key gait parameters in real-time.
  • Accelerometer data provided insights into leg angles.
  • Gyroscope data accurately determined stride frequency.
  • Calculated number of strides and linear velocity were statistically validated.
