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. This service type has the disadvantage that it is difficult to perform situations other than the set functions; for example, users can only perform commands provided by the application installed on the user terminal, and perform other controls. You can't do it. Therefore, this technology proposes a method that can accurately infer the user's current situation from surrounding environment information and behavior patterns.
This technology can improve users' living convenience by intelligently providing a living space management service tailored to residents' situation information, and since context information is shared through a blackboard, it has the advantage of being easily linked to additional devices.

Passenger impact measurement method to prevent insurance disputes
This technology is a shock measuring device for passengers, and in particular, it relates to a shock measurement method that can calculate the impact amount in the event of a traffic accident, convert it into data, and use it as medical and insurance data by placing an impact amount measuring device on the headrest of a vehicle.
Since treatment costs and alimony are paid differently in existing traffic accidents, both insurance companies and victims cannot obtain satisfactory results, and this technology proposes a method for measuring the impact amount that passengers receive by converting data on the amount of impact received by passengers during traffic accidents, predicting the degree of injury to passengers and using it in insurance data to prevent disputes.
Since this technology can be used in disputes related to excessive repair costs, insurance claims, etc., it has the effect of preventing traffic accidents and contributing to reducing waste, and it is expected that it can be used to accumulate data and predict treatment and recovery periods for concussions, neck injuries, etc., even when not equipped with an impact measurement device for passengers.
