Disclosed are an apparatus and a method for controlling a room lamp of a vehicle. The present invention relates to collecting information associated with the vehicle and information associated with an ambient environment using a global positioning system (GPS) or a controller area network (CAN) and then controlling the room lamp using at least one of turn-off of the room lamp, change of an irradiation angle of the room lamp, and adjustment of illumination of the room lamp based on the collected information.

Provided are a route guidance system and method for emergency vehicle using telematics. The route guidance system includes an instruction station, a vehicle telematics and a traffic signal controller. The instruction station sends destination information to an emergency vehicle for dispatch due to an occurrence of an emergency circumstance. The vehicle telematics is attached to the emergency vehicle, and searches a plurality of travel routes on the basis of the destination information to provide the shortest travel route. The traffic signal controller controls a corresponding traffic signal on the travel route before the emergency vehicle approaches on the basis of travel information sent from the vehicle telematics.

Provided are a node update system using virtual partition technique and a control method thereof. A storage region of a sensor node is divided into a non-updatable invariable region and an updatable variable region to be virtually generated according to an execution operation of the sensor node. The states of the sensor nodes are monitored, and an update request signal is transmitted to a corresponding sensor node when update is necessary. Execution image information is received, and the execution image information is stored in the variable region to update an execution image, according to a response signal to the update request signal.

The present invention relates to a system and method of transmitting an emergency condition using a wireless sensor network that transmits a user's emergency condition using a wireless sensor network. A wireless sensor network communication device integrated with a biological sensor is attached to a user's body in order to gather user's biological information, and transmits the user's biological information through the wireless sensor network. A repeater receives the biological information from the communication device, and sends the received biological information by using a routing protocol of the wireless sensor network. A management server receives the biological information through the repeater, analyzes the biological information, and transmits a warning signal to a user or takes emergency measures. Therefore, it is possible to detect and cope with sudden physical problems, which are generated during user's exercises and outdoor activities, at an early stage. As a result, it is possible to significantly contribute to the prevention and reduction of danger for the weak and the elderly, and a user who is to be taken care of.

An ATM cell demultiplexing control apparatus comprising an ATM switch interface circuit for performing an interface function with an ATM switch link and outputting ATM cell data received from the ATM switch link and a start signal, a register circuit being enabled in response to the start signal from the ATM switch interface circuit, the register circuit shifting the ATM cell data received from the ATM switch interface circuit to extract a virtual path indicator therefrom and outputting the extracted virtual path indicator and the received ATM cell data, a memory for storing a virtual path indicator table therein and outputting information listed in the stored virtual path indicator table as a processor routing bit map in response to the virtual path indicator from the register circuit, a local processor for updating the virtual path indicator table stored in the memory, a processor cell transmitter for outputting a reception FIFO selection signal in response to the processor routing bit map from the memory to rout the output data from the register circuit, and a plurality of reception FIFO memories being selectively enabled in response to the reception FIFO selection signal from the processor cell transmitter, the reception FIFO memories storing the output data from the register circuit therein and outputting the stored data.
摘要:
A method for transmitting data for inter-frequency/inter-system handover in an asynchronous UTRA mobile telecommunications system, wherein information incapable of being transmitted for an idle period is transmitted over a common channel in the case of the inter-frequency handover or inter-system handover, thereby increasing the quality of speech and more efficiently performing the handover. A base station assigns a common channel to a mobile station connected thereto if inter-frequency (inter-system) handover is requested by the mobile station. Then, the base station transmits information about the assigned common channel to the mobile station and determines whether a transmission frame is an idle frame. The base station transmits data to the mobile station over a dedicated channel if the transmission frame is not the idle frame and over both the dedicated channel and common channel if the transmission frame is the idle frame. If a received frame is the idle frame during data reception, the mobile station receives data from the base station over both the dedicated channel and common channel. Therefore, the present invention has the effect of overcoming a conventional code shortage problem and, because of the assignment of one OVSF code to a common channel, keeping orthogonality with other channels.
