A method and apparatus for setting up a wireless LAN. The method includes receiving a packet, which informs a user that a WPS (Wi-Fi Protected Setup) button of an access point is operated, from the access point; activating a button provided in an image forming apparatus as a WPS button; selecting a button activated as the WPS button; and if the button activated as the WPS button is selected, establishing a wireless network with the access point.

An apparatus and method for generating a key for a broadcast encryption. The apparatus includes a node secret generator for managing a user that receives broadcast data in a tree structure and for generating a unique node secret for each node in the tree structure. The apparatus also includes an instant key generator for temporarily generating an instant key used at all nodes in common in the tree structure, and a node key generator for generating a node key for each node by operating the node secret generated at the node secret generator and the instant key generated at the instant key generator. Thus, key update can be efficiently achieved.

A heater of a thermal inkjet printhead. The heater is formed of tantalum aluminum oxynitride (Ta—Al—ON), wherein the tantalum aluminum oxynitride is formed of about 30 to about 60 atomic % tantalum, about 10 to about 30 atomic % aluminum, about 5 to about 30 atomic % oxygen, and about 5 to about 30 atomic % nitrogen.
摘要:
An inkjet printhead and a method of manufacturing the printhead. The inkjet printhead includes a substrate through which an ink supply passage is formed, a chamber plate stacked on the substrate having an ink chamber filled with ink supplied through the ink supply passage and heating resistors to heat the ink formed in the ink chamber, a nozzle plate formed on the chamber plate and through which a plurality of nozzles through which ink is ejected are formed, and a water repellent layer formed on the nozzle plate, wherein portions of a covalent bond formed by reaction between the material forming the nozzle plate and a hydrolysis material used to form the water repellent layer are discontinuously formed.
摘要:
A print control method of a host apparatus which is connected to at least one image forming apparatus in a network, the method including receiving changed IP information from the at least one image forming apparatus; determining whether the host apparatus performs a print job with respect to the image forming apparatus which has the changed IP information; holding the print job if there is the print job; changing a print option for the print job; and transmitting print data corresponding to the print job according to the changed print option. With this, the apparatus and the method may normally perform a print job by changing a port of an image forming apparatus and prevent data loss due to a failure to change the port normally even if there is a print job for an image forming apparatus whose IP address is changed.
摘要:
An authentication method in a home network having at least one communicatable device and a home server which controls the devices, in which the home server authenticates the devices forming the home network. The home server generates the authentication key using the stored unique information of the home network device, and sends the generated authentication key together with the unique information to the device. The home server compares the operation value with respect to the generated authentication key and the unique information with the value received from the device, and completes the authentication when the two values are the same.

A system and method for configuring a device using a remote controller are provided. The system includes at least one device which transmits and receives data using a wireless communication connection and performs a preset operation according to a received control signal; a server which communicates data with the at least one device over a radio channel and controls functions of the at least one device; and a short distance wireless communication device that authenticates the at least one device by receiving a device address list through radio communications with the server and assigning a device address selected from the received address list to the at least one device. Thus, inputting password information of the device directly to the server is not required when a new device is configured.
