Abstract: A remote diagnostic system (RDS) data security device and method are provided, in which an interface unit receives an RDS command from a host, a storage unit stores a security setting for RDS data, and a control unit performs an operation for the RDS data according to the RDS command and the security setting, wherein the result obtained by the performance is selectively transmitted externally. Accordingly, since the reading and writing operations of RDS data are performed according to an RDS command received from the host and previously stored security setting, and the result obtained by the reading and writing operations is displayed, data collected in the RDS can be prevented from being transmitted to the server without permission, and data allowed to an authorized user can be transmitted to the server.

Abstract: A method of manufacturing a monolithic inkjet printhead wherein the uniformity of the ink flow path is maintained by ensuring that the flow path forming layer and the nozzle layer are completely adhered to each other. The method includes forming a heater and electrode on a substrate, coating a negative photoresist on the substrate, and patterning the photoresist using a photolithography process to form an flow path forming layer that defines an ink flow path. The method further comprises steps for then forming a sacrificial layer so as to cover the flow path forming layer and then flattening upper surfaces of the flow path forming layer and the sacrificial layer using a chemical mechanical polishing (CMP) process such that when a nozzle layer is then formed, the flow path forming layer and the nozzle layer are completely adhered to each other.

Abstract: A method of manufacturing a monolithic inkjet printhead. The method may include forming on a substrate a heater for heating ink and an electrode for supplying current to the heater, forming a passage forming layer that surrounds an ink passage by applying negative-type photoresist to the substrate and patterning the same, forming a sacrificial layer having a planarized top surface in a space surrounded by the passage forming layer by repeatedly applying a positive-type photoresist to the substrate having the passage forming layer and patterning the same by photolithography at least twice, forming a nozzle layer having a nozzle by applying a negative-type photoresist to the passage forming layer and the sacrificial layer and patterning the same, etching the substrate from the bottom surface thereof to be perforated and forming an ink supply hole, and removing the sacrificial layer. Since the top surface of the sacrificial layer is planarized, the shape and dimension of the ink passage can be easily controlled, thereby improving uniformity of the ink passage.

Abstract: An inkjet printhead and a manufacturing method thereof. The inkjet printhead includes a substrate, a substantially cylindrical ink chamber storing ink and formed in an upper portion of the substrate, and a manifold supplying ink to the ink chamber in a bottom portion of the substrate, a channel-forming layer disposed between the ink chamber and the manifold and having an ink channel communicating between the ink chamber and the manifold, a nozzle plate stacked on the substrate and having a nozzle at a location corresponding to the central part of the ink chamber, a heater formed to surround the nozzle of the nozzle plate, and electrodes electrically connected to the heater to supply current to the heater. Therefore, the quantity of ink stored in an ink chamber can be increased. Also, when bubbles grow, the cylindrical ink chamber confines an ink flow area to ink ejectors, thereby reducing a back flow of the ink. Further, the quantity of ink supplied to the ink chamber can be adjusted by varying the number of ink channels formed in the channel-forming layer, thereby improving frequency characteristics of the inkjet printhead.

Abstract: A station and a method of collecting information corresponding to security. A wireless communicator transmits a request packet to search a wireless network to at least one external device and receives a response packet to the request packet. An authentication method determiner analyzes the response packet to search for at least one wireless network and determines an authentication method supported by each of the searched wireless networks. A storage unit stores the determined authentication method of each of the searched wireless networks. Thus, necessary information corresponding to security during a connection to a wireless network can be searched in advance and provided to a user.
