An error management system for managing an error occurring in a client application includes: a client terminal which intercepts an event, and collects error information and a crash dump file when the client application is abnormally terminated, and transmits the collected error information and the crash dump file in a predetermined format via a network; and an error collecting server which receives the error information and the crash dump file from the client terminal, and stores the received error information and the crash dump file for each online service, the error collecting server being independent from an online service server that executes a server application providing a service in correspondence to the client application.
摘要:
A channel selecting method for a Wireless Local Area Network (WLAN) using remote scanning and a WLAN system thereof is disclosed in which a wireless environment is comprehensively discriminated to select an optimum channel by information. The information is obtained from stations of each node (STA) in a wireless network and is not local information near the Access Point. Channel selection is configured to be automatically implemented during an initial configuration of the WLAN and during operation. The method includes the AP requesting remote scanning for each node (STA) comprising the WLAN. Each node transmits a remote scanning result to the AP. An optimum channel is discriminated and a determination is made as to whether transfer has been made to the channel based on the information received from each node. The AP, transferring to the optimum channel, thus discriminated to form a new WLAN if channel transfer is implemented according to the discrimination.
摘要:
A wireless LAN device and a method of monitoring the status of a wireless LAN are disclosed. The wireless LAN device according to the present invention can determine the status of a wireless LAN using a variety of information obtained by performing media access control (MAC) without additional packet transmission/reception with a correspondent wireless LAN device. Accordingly, if the wireless LAN device of the present invention is various kinds of wireless A/V (Audio/Video) devices that provide the A/V streaming, the data transmission can be optimally made in accordance with the status of the monitored wireless LAN. Further, since there is no additional communication needed to monitor the status of a wireless LAN, the present invention has advantages in that the processing speed of the wireless LAN device is improved and the traffic of the wireless LAN is not increased.
摘要:
An A/V equipment and a channel selecting method are disclosed, wherein the A/V equipment forms a wireless network by using information of each channel obtained by scanning each channel of a monitoring channel set to compute a predetermined parameter, and comparing the computed parameters to select an optimum channel. Consequently, the A/V equipment is configured to form a wireless network at a channel in which the wireless environment is the most satisfactory, thereby being enabled to satisfy a QoS requirement and to provide good quality of service, and to effectively distribute frequency resources under an environment, where the wireless equipment is mixed exists
摘要:
An apparatus and method are disclosed to control an operation of a reciprocating compressor capable of precisely controlling an operation (stroke) of a reciprocating compressor regardless of a parameter of an internal motor of the reciprocating compressor and a mechanical error of the reciprocating compressor. The apparatus for controlling an operation of a reciprocating compressor which determines a stroke estimate value corresponding to a point when a discharge valve of the reciprocating compressor is opened as a stroke reference value, and controls a voltage applied to the reciprocating compressor according to the determined stroke reference value.
摘要:
An apparatus for transferring an upright tray at high speeds that can sense an entrance and discharge of the tray. The apparatus includes a transferring unit with pulleys driven by a driving source to form a transferring path. The pulleys contact a fixing member, which is attached to a lower edge of a substrate and mask fixed to the tray. The apparatus also includes a sensing unit with a sensor installed beneath the transferring path to detect the entrance and discharge of the tray. The apparatus may also include rollers disposed to contact both sides of the upper portion of the tray, and the rollers may be coupled with moveable members encased within rails along the transferring path so that the rollers can translate when a tray passes between two rollers. The rollers along both sides of the tray can be arranged symmetrically or alternately in a zigzag pattern.
