Filed: 2000-07-20
Abstract: PURPOSE: A measuring method of image density on a photosensitive unit is provided to check the image density changes of a printer by measuring the image density on a photosensitive unit. CONSTITUTION: A set test pattern image is formed on a photosensitive belt if a developing density checking mode is set(100). If inner test pattern image data are set to form a test pattern image of 10% in density on the photosensitive belt, a controller scans beam corresponding to the image data of 10% in density to the photosensitive belt by controlling a scanner. The electrostatic latent image of the formed test image is developed by a developer having a yellow developing solution. If the test image reaches a light receiving area of a detector, the detector detects the incident beam from the test image-formed area and outputs the color elements of the detected beam separately(110). The controller provides the yellow color data of the test image to a density calculator in the developing density checking mode. The density calculator balances sub-color elements from the main color elements of the yellow color and calculates the density of the test image through a lookup table(120). The controller decides the density capability of a printer by comparing the calculated density with set value. The result is used for adjusting the operating conditions of each unit.

Title: Method for traffic controlling of signaling gateway
Inventor: PARK SO HYEON
IPC: H04L12/66
Filed: 2000-10-02
Abstract: PURPOSE: A method for controlling a signal traffic of a signal gateway is provided to previously prevent that the signal gateway is overloaded by cleaning messages stored in a queue when a call connection agent is not recovered during a uniform time and limiting a newly inputted signal traffic in an origination point SEP(Signaling End Point). CONSTITUTION: It is judged whether a recovery timer is time-out(S14). In case that the recovery timer is time-out, an SS7 signal message stored in a queue is cleaned(S16). A signal gateway formats a TFC(Traffic Flow Control) message and transmits the formatted TFC message to an SEP(S18). If a call connection agent recovery state primitive for informing that at least one or more call connection agents are recovered is received from a call connection agent(S20), the signal gateway designates a congestion level of the TFC message as '0' to transmit the TFC message to the SEP and notifies the SEP that the signal gateway normally converts the SS7 signal message into data and transmits the data to the call connection agent so that a signal traffic flow function is normally resumed(S22). If the signal gateway stores a state of the call connection agent as a recovery state and the call connection agent receives a call connection active state primitive(S24), the SS7 signal message is converted into data and the data are normally transmitted to the active call connection agent(S26).

If so, the front controller previously informs a main controller of a power-off state, and the main controller suspends an operation to enter a power-off mode(22). The front controller controls an intercepting of power in a power supplier, and controls power supply after a set time. The power supplier turns off each unit of a web box, including the front controller and the main controller. If the set time elapses, the power supplier supplies power again.
