Abstract: A proximate location detection system includes a wireless signal transmitter and a wireless receiver and light emitter. The wireless signal transmitter receives power in response to a first pressure signal and transmits repeatedly a transmission signal generated in response to a second pressure signal during a preset period. The wireless receiver and light emitter receives the transmission signal from the wireless signal transmitter and emits light of various colors using a Light-Emitting Diode (LED) lamp or laser lamp array.

Abstract: A field monitoring system using a mobile terminal includes at least one mobile terminal which transmits situation information including video information, audio information and location information and receives three-dimensional (3D) image information corresponding to the situation information, and a control server which receives the situation information from the mobile terminal, generates 3D image information about a current location of the mobile terminal by matching the location information of the situation information with pre-stored map information or architectural drawing information, and transmits the 3D image information to the mobile terminal. The video and audio information is generated by capturing video and sound of a field, and the location information is generated by integrating signals sensed by an accelerometer and a gyroscope sensor with a Global Positioning System (GPS) signal including latitude, longitude and time.

Abstract: The present invention relates to a system and method for controlling the aimed shooting of a sniper and the observation of a spotter. At the same time that a sniper directly checks the shape of the target using a sighting telescope, a spotter observes the surroundings of the target using an observatory telescope. The sniper deflects images of the target using a prism, focuses the images, and converts the focused images into digital moving image signals. The spotter deflects images of the target using a prism, focuses the images, and converts the focused images into digital moving image signals. Two types of images can be selectively transmitted, or can be combined with each other using a multiplexer and transmitted to a shooting controller in a multi-screen division form. A commanding office can identify a precise target and make a decision pertaining to shooting.

Abstract: The present invention relates to a system and method for transmitting video of an entire law enforcement processing. The system includes a portable video storage device provided to be detachably worn on an arbitrary portion on a helmet, goggles, or a body of a law enforcement officer and is configured to store and manage first law enforcement information and to transmit the first law enforcement information. A vehicle-use video storage device is provided on a front and a rear portion of a police vehicle and is configured to compress second law enforcement information, store the compressed second law enforcement information, and transmit the first and second law enforcement information. The police station server generates law enforcement record information by combining the first law enforcement information and the first and second law enforcement information, stores and manages the law enforcement record information, and outputs indexed law enforcement record information.
