Abstract:
Disclosed is a car seat system for reducing false alarm occurrences and a method for operating the car seat system. A car seat system according to one embodiment of the inventive concept includes a sensor unit including a plurality of sensors including a pressure sensor, and sensing an object on a car seat, a sensor controller that controls a main controller to enter a wake-up mode from a sleep mode when pressure information sensed about the object is received from the pressure sensor, the main controller that, upon entering the wake-up mode by the sensor controller, determines the object based on information sensed by each of the plurality of sensors and received via the sensor controller, and provides a beacon signal about the object based on the determination, and a transmitting unit that broadcasts the beacon signal from the main controller.
Abstract:
An image monitoring system for vehicle for detecting a left lane area and a right lane area behind a vehicle using a region of interest (ROI) is provided. The system includes a rear camera, a memory configured to store an image obtained from the rear camera, and a controller configured to be set to one of a driving mode and a parking mode based on whether the vehicle is traveling and to detect an event from the image obtained from the rear camera. The controller set to the driving mode sets the ROI corresponding to the left lane area and the right lane area behind the vehicle on the image obtained from the rear camera, while the vehicle is traveling, detects whether an object is located on or enters the ROI, and notifies a driver of the vehicle of the detected result using an alarm.

Abstract:
The present invention relates to an energy supply circuit for instantly supplying power without a power converter and an electronic device which operates only when energy is supplied from an energy source using the same. An energy supply circuit without a power converter according to the present invention comprises: an energy extraction unit 10 for generating power from an energy source; and output unit 20 for supplying power to an external electronic circuit; a switch unit 30 interposed between the energy extraction unit and the output unit 20 to connect an output end of the energy extraction unit 10 to the output unit 20 when switched on; and a maximum power point tracking control unit 40 for generating an open/closed signal for opening or closing the switch unit 30 according to the voltage and current of the energy extraction unit 10. The present invention has a technical feature wherein a turn-on point of the open/closed signal comes at a time when the output end voltage of the energy extraction unit 10 is Vh, and a turn-off point comes at a time when the output end voltage of the energy extraction unit 10 is Vl. Accordingly, the present invention has a simple configuration, low manufacturing costs, has no energy loss due to the power conversion, and has no reduction in life due to charging and discharging of an energy storage device.
