Electronic Distance Measuring Instruments

Electronic Distance Measuring Instruments

Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over short distances...

Ultrasonography

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...

Purpose of the Study:

To develop and validate a new ultrasonic system for measuring human stride length.
To enable precise characterization of gait parameters.
To provide a foundation for advanced biomechanical analysis.

Main Methods:

A system utilizing ultrasonic transmitters and receivers, radio transmitters and receivers, and microcontrollers was developed.
The system synchronizes ultrasonic and radio signals to measure signal propagation time.
Stride length is calculated using measured distances and a cosine function.

Main Results:

The system successfully measures the time of flight for ultrasonic signals between shoes.
Distances between shoes are accurately calculated based on signal travel time and ultrasound velocity.
Stride length is determined using these distances and the dimensions of the shoe.

Conclusions:

The developed ultrasonic system offers a novel and accurate method for stride length measurement.
This technology has significant potential for applications in gait analysis and biomechanics.
The system provides a basis for detailed characterization of human locomotion.
