Abstract:
Provided are a method and a device for controlling a vehicle approaching an intersection, and more particularly, a method and a device for controlling a vehicle approaching an intersection, which controls a vehicle approaching an intersection by selecting a traffic signal for the vehicle. The method of controlling a vehicle approaching an intersection includes: collecting traffic light information including signal cycles and positional coordinates of traffic lights installed at the intersection; selecting a corresponding traffic light among the traffic lights in consideration of positional information of the vehicle at the intersection and the positional coordinates of the traffic lights; and controlling the vehicle on the basis of the signal cycle of the corresponding traffic light.
Abstract:
Provided is a routing method for a guard lamp using a short distance wireless communication, the method including: performing, by a neighbor setup guard lamp, a neighbor setup operation; transferring, by the neighbor setup guard lamp, an initialization request message (Init_Request Message) to a neighbor guard lamp and receiving an initialization response message (Init-Rep Message) from the neighbor guard lamp to form a guard lamp network; receiving, by the neighbor setup guard lamp, a data message from the neighbor guard lamp; and repairing a path of the neighbor guard lamp having an error caused by a link loss at the receiving of the data message.
Abstract:
A method of forming a frame in a Mobile Multi-hop Relay (MMR) system, and a system for implementing the method are provided. In a multi-hop relay system, when a relay station of a specific layer receives data, the relay station receives data from both a higher layer and a lower layer. When the relay station transmits data, the relay station transmits data to both the higher layer and the lower layer. By doing so, data reception and data transmission are exclusively performed without interfering with each other, and the method and the system are easily applied to the multi-hop MMR system.
Abstract:
A terminal main body of a communication terminal is supplied power from a battery pack through a DC signal path. The terminal main body communicates with at least one additional function module providing an additional function through a communication path connected to the DC signal path so as to provide the additional function to a user. Herein, the communication path is an AC signal path. That is, a signal transmitted/received between the terminal main body and the additional function module is an AC signal, and thus, the communication path can be compatible with the DC signal path providing the power. In addition, a plurality of additional function modules can be serially connected in the form of a serial communication bus, and therefore, a user can select a plurality of additional functions.

Abstract:
A compressor designed to discharge a refrigerant compressed in the compressor to the outside through a cylinder head and a discharge muffler. The compressor is designed to prevent heat of a refrigerant passing through a discharge chamber and the discharge muffler in the cylinder head from being transferred to a compressing chamber, thereby enhancing efficiency of the compressor. The compressor includes the discharge chamber to contain temporarily a refrigerant compressed in a compressing chamber, and a heat-radiating member to radiate heat from the discharge chamber to the outside.
Abstract:
A static excitation system that can eliminate shaft vibrations of a generator and overvoltage when it is underexited is provided. The static excitation system includes an initial excitation equipment; a step-down transformer; a 3-phase diode bridge; a boost chopper provided with a transistor and a resister, and maintaining DC voltage to be constant; a DC chopper provided with a plurality of transistors and diodes, and supplying DC power to a rotor of a generator; a boost controller for controlling the boost chopper; and a DC chopper controller for controlling the DC chopper, wherein, overvoltage applied on the excitation system when underexcited is eliminated owing to the boost chopper preventing any changes at an output terminal of the generator from being transferred to the excitation system, and maintaining the excitation DC voltage to be constant; and also owing to the DC chopper which is capable of 4 quadrant operation, hereby pole slipping of the generator can be prevented.
Abstract:
A rotor of a synchronous motor and a method of manufacturing the same. The rotor of the synchronous motor comprises a main core, formed from a plurality of laminated thin iron sheets, the thin iron sheets having a hole at a center for receiving a rotating shaft, and a number of magnet holes and induced conductor holes radially disposed in the thin iron sheets at a predetermined space differently from the hole. A plurality of magnets are inserted into the magnet holes of the main core. Supplementary cores, having a hole and induced conductor holes corresponding to the hole and the induced conductor holes of the main core, are disposed at the ends of the main core wherein the magnet is inserted. An induced conductor formed by ingoting through the induced conductor holes of the main core and the induced conductor holes of the supplementary cores. Consequently, through the induced conductor and the magnet, the efficiency of the motor can be improved. Furthermore, productivity can be also increased because of shortened manufacturing procedure, since the magnet is naturally secured by ingoting the induced conductor through the main core and the supplementary cores.
