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.

Bridgeless interleave power factor correction circuit to reduce power loss
This technology relates to a bridgeless interleave power factor correction circuit and driving method, and more particularly, to a bridgeless interleave power factor correction circuit and driving method for battery charging devices for electric vehicles.
Converters with conventional bridgeless interleaved power factor correction circuits have the problem that high efficiency can only be achieved due to high EMI noise, low utilization of circuit components, and complex feedback circuits. Thus, this technology proposes a method that can have a high device utilization rate while being implemented with few active elements by merging at least two merged boost legs into a single high-speed diode.

This technology relates to a method for configuring three-phase coils. Specifically, it concerns a method for configuring three-phase coils in a bearingless motor that allows for determining a bearingless three-phase coil structure using the minimum number of coils through mathematical modeling.
As the adoption of electric vehicles accelerates and interest in energy conservation and environmental protection grows, the demand for energy-saving, high-efficiency motors is increasing. However, conventional motor systems are the components that fail first due to friction between rotor parts; to overcome this, non-contact support motors have been developed.
