Ultrasonic Slope Measurement Device
This technology concerns a device and method for measuring inclination using an ultrasonic sensor. More specifically, it describes a method for measuring inclination by transmitting and receiving ultrasonic waves via an ultrasonic sensor while positioned at a distance from the inclined surface.
Conventional methods for determining inclination using accelerometers and gyroscopes suffer from errors during the integration process, limiting their ability to accurately determine the ground's inclination. Therefore, we propose an inclination measurement device and method utilizing an ultrasonic sensor.
This technology enables safer and more accurate inclination measurements compared to conventional methods, as it can measure the slope by transmitting and receiving ultrasonic waves via an ultrasonic sensor while positioned away from the inclined surface.

Method for providing living space management services using ontology-based situation inference techniques
This technology relates to an apparatus and method for providing a living space management service using ontology-based situation inference techniques.
Conventional smart home services are a form of transmitting home environment information to users through a server with a smart home controller installed and controlling home appliances from outside the home through information provided by the user.
