Abstract: A method for monitoring a dangerous situation in a space based on a frequency response pattern according to an embodiment includes loading, by a processing unit of a mobile terminal located in the arbitrary space, a setting value corresponding to an operational mode selected through control software installed on the mobile terminal, controlling, by the processing unit, a speaker of the mobile terminal to generate a frequency corresponding to the loaded setting value, receiving the frequency which was generated in the controlling and reflected in the space through a microphone of the mobile terminal, determining, by the processing unit, whether the dangerous situation occurred in the space by comparing the frequency response pattern with a preset reference value, and taking, by the processing unit, a follow-up action when it is determined that the dangerous situation occurred in the space by the determining.

Abstract: An artificial intelligence (AI) based method for controlling a multimedia device according to an embodiment of the present disclosure makes it possible to ensure accuracy in detection and interpretation of a voice command of a user by enabling an AI care device to control the volume of the multimedia device by itself or allow the user to control the volume of the multimedia device by transmitting voice guidance for volume control to the user when the AI care device does not accurately detect the voice signal of the user due to the audio signal of the multimedia device and the voice signal of the user applied to the AI care device at the same time.

Abstract: An assistive system according to an embodiment of the present disclosure includes a cradle module including a holder body on which a user terminal is to be placed and a drive unit configured to drive the holder body, the cradle module configured to output a terminal connection signal when the user terminal is placed on the holder body, and an assistant server configured to receive the terminal connection signal from the cradle module and execute an assistive service, the assistant server configured to control the drive unit by a preset drive pattern through a drive control signal when executing the assistive service. It is possible to easily and conveniently identify a plurality of assistive services outputted according to each situation by controlling a cradle module through a drive pattern corresponding to an assistive service while outputting a voice corresponding to the assistive service when executing the assistive service.

Abstract: An assistive system according to an embodiment of the present disclosure includes a cradle module including a holder unit and a driving unit to rotate the holder unit, and a user terminal placed in the holder unit and controlling the driving unit by outputting a driving control signal. It is possible to provide an assistive service at a low cost without any assistive robot. In addition, it is possible to execute the assistive service by simply placing the user terminal in the cradle module without any manipulation, thereby providing convenience of use, and it is possible to efficiently provide a user with output information outputted through the cradle module and the user terminal, and provide an environment just like having conversation with a real character when providing the assistive service, thereby improving intimacy and reducing loneliness in the user.

Abstract: A user care system accuses a chatbot. According to an embodiment of the present disclosure, not only a current state of a user can be quickly determined on the basis of a content of a conversation between a chatbot and the user, but also the user can quickly receive help from the outside when it is determined that the user is in a dangerous situation. Further, not only the chatbot can quickly determine a current state of the user on the basis of a change in biometric information of the user, but also the user can quickly receive help from the outside when it is determined that the user is in a dangerous situation.

Abstract: A state display information transmission system uses a chatbot. According to an embodiment of the present disclosure, in a user terminal and a counterpart terminal, in which a SNS service, an instant message service, etc. operates, even when the user terminal does not respond within a preconfigured response time, a chatbot transmits proper emoticon information, etc. to the counterpart terminal, so that a user can continuously make smooth and proper communication with a counterpart.

Abstract: A stereo and dual audio signal identifying circuit including an FM detector receiving a second intermediate frequency signal, a bandpass filter, an AM detector. The circuit further including an amplifier having a first input receiving an output signal from the AM detector, and a second input receiving a signal derived from a series connected resistor and DC-filtering capacitor connected between the second input and ground, and having a feedback resistor connected between the second amplifier input and the amplifier. The amplifier drives a second stage of the circuit including a voltage controlled oscillator, a phase detector and a low-pass filter. The particular disposition of the DC-filtering capacitor within the circuit allows the capacitor to be externally connected to a single pin in an IC package incorporating the circuit.
