Abstract: PURPOSE: A route information providing method using a navigation system is provided to reduce errors caused by passing through an intersection because a time required for passing through the intersection existed on a route is reflected when selecting the route. CONSTITUTION: A route information providing method using a navigation system is as follows. A current location of a user is figured out based on location data received from a GPS satellite(S200). A route to a destination from the current location is searched by using road information saved in a navigation system(S210). If a plurality of the routes is searched, a time required for passing through an intersection on the route is calculated(S240). One route among the plurality of the routes is selected based on the time required(S250).

Abstract: An optical modulator, a method and an apparatus for controlling a bias voltage of the optical modulator are provided to control bias voltages of two optical modulators efficiently through feedback control of the bias voltages according to detection of a fourth harmonic signal to maintain final output characteristic with stability. An optical modulating device includes a light generator(11), a first optical modulator(12), a second optical modulator(13), and a bias controller. The first optical modulator turns on/off light generated by the light generator according to a reference clock signal to modulate the light into an optical pulse signal with a predetermined period. The second optical modulator turns on/off the optical pulse signal output from the first optical modulator according to data to be modulated to modulate the optical pulse signal into an optical output signal with the data loaded thereon. The bias controller applies a first low-frequency RF signal with a first bias voltage to the first optical modulator, applies a second low-frequency RF signal with a second bias voltage to the second optical modulator, detects a fourth harmonic component of the first RF signal from the optical output signal of the second optical modulator and controls the first bias voltage and the second bias voltage such that the fourth harmonic component has a minimum current.

Abstract: A method and an apparatus for guaranteeing a differentiated bandwidth for each service in an ethernet frame transmission system are provided to guarantee a differentiated bandwidth for each service by setting a different pause time according to a priority level assigned to each service when a pause frame is generated for the reason of congestion or a failure. A frame transmitting/receiving unit(10) transmits/receives ethernet frames through multiple ports. A MAC(Media Access Control) processing unit(20) recognizes information on an available current ethernet network according to congestion or a system failure by monitoring the multiple ports, and interprets a received ethernet frame. An input ethernet frame buffer(30) temporarily stores the received ethernet frame. A signal processing unit(60) sets a different pause time according to each priority level assigned to each service based on memory state information of the input ethernet frame buffer(30) and the availability information, adds a pause frame including the set pause time in a MAC control frame, and transmits it to adjacent nodes. A network processor unit(50) classifies ethernet frames inputted from the input ethernet frame buffer(30) by service, assigns a priority level, and outputs them. An output ethernet frame buffer(40) temporarily stores the outputted ethernet frames.
