Abstract: Provided is a brain-machine interface based intention determination device using a virtual environment, including: an input unit that receives a control mode; a training output unit that outputs training information; a collection unit that collects a brain signal; a first preprocessing unit that extracts time-frequency information; a second preprocessing unit that generates physical information; a learning unit that learns control information according to a pattern of physical information; a determination unit that determines control information; and a command output unit that outputs a control command matching the control information.

Abstract: The present disclosure relates to a pacemaker module including a case unit, a vertical movement guide, an atrial sensor, and a pacemaker. The pacemaker module according to the present disclosure has an excellent effect in that it is capable of accurately measuring the flow of current in the entire heart and capable of being accurately and consistently operated with a simple operation, which makes it possible to accurately implant the pacemaker module.

Abstract: Provided is a notebook battery protection circuit package including a package substrate, a fuel gauge integrated circuit (FGIC) module mounted on the package substrate, a protection integrated circuit (IC) module mounted on the package substrate, a charge/discharge transistor module mounted on the package substrate, and a mold provided on the package substrate to encapsulate the FGIC module, the protection IC module, and the charge/discharge transistor module into one.

Abstract: A clock synchronization circuit includes a delay-locked loop (DLL) and a delay-locked control unit. The DLL is configured to generate an output clock signal by delaying an input clock signal by a delay time, and to execute a delay-locking operation in which the delay time is adjusted to a locked state according to a comparison between the output clock signal and the input clock signal.

Abstract: Disclosed is a street lamp control system, which cuts off power sources only around an abnormal street lamp where an electric leakage or dangerous situation occurs and allows the rest street lamps to be kept being turned on. The street lamp control system is positioned in a region divided by a plurality of areas where a predetermined number of street lamps are installed. A distribution panel is installed in each center of the areas, and includes two power source control switching circuits for controlling right and left power sources of the corresponding areas. The power source control switching circuit of the corresponding distribution panel turns off the right and left street lamps including the corresponding street lamp when an abnormal state is sensed on a specific street lamp of a specific area, and a power is supplied to the right and left street lamps to be turned on excluding the abnormal street lamp.
