Abstract:
A gate driving apparatus includes a first stage which outputs a first gate output signal, and a second stage which outputs a second gate output signal. The first stage includes: a transistor which includes a gate electrode, a source electrode and a drain electrode; and a dummy transistor which includes a dummy gate electrode, a dummy source electrode and a dummy drain electrode. The gate electrode receives the second gate output signal, and the dummy source electrode is connected to the source electrode or the drain electrode of the transistor and prevents static electricity from flowing to the first stage.
Abstract:
An elastic body for measuring loads and a non-contact load-measuring device are disclosed. The elastic body includes: an elastic body base; a multiple number of slits formed in the elastic body base; and a deforming space part formed in the elastic body base. Inside the deforming space part are formed: a hinge, a first deforming part coupled with the hinge, and a second deforming part that is coupled with the first deforming part and the hinge and is formed with a greater length than that of the first deforming part. The first deforming part and second deforming part are configured to undergo rotational movements about the hinge in correspondence to the load, the first deforming part moving downwards in correspondence to the load and the second deforming part moving upwards in correspondence to the load. The upward displacement of the second deforming part is used for measuring the load.

The present invention improves a data loading speed and enhances power consumption property by reducing current dissipation.
Abstract:
A server certificate verification method in a terminal during. Extensible Authentication Protocol authentication for Internet access is provided, the method including (a) receiving a server certificate from a wireless LAN authentication server, and transmitting a server certificate verification request message of the server certificate to a wireless LAN authentication server via a wireless LAN access server; (b) transmitting by the wireless LAN authentication server an On-line Certificate Status Protocol request message to an On-line Certificate Status Protocol server to verify the server certificate; (c) receiving a result of the server certificate verification performed by the OCSP server using an Extensible Authentication Protocol packet from the wireless LAN authentication server; and (d) determining whether the result of the server certificate verification is valid.
Abstract:
Vertical channel semiconductor devices include a semiconductor substrate with a pillar having an upper surface. An insulated gate electrode is around a periphery of the pillar. The insulated gate electrode has an upper surface at a vertical level lower than the upper surface of the pillar to vertically space apart the insulated gate electrode from the upper surface of the pillar. A first source/drain region is in the substrate adjacent the pillar. A second source/drain region is disposed in an upper region of the pillar including the upper surface of the pillar. A contact pad contacts the entire upper surface of the pillar to electrically connect to the second source/drain region.

The intrusion detection system of a wireless network includes: an access point providing wireless communication to a wireless terminal; and an intrusion detection sensor examining packets transmitted and received between the access point and a wireless terminal according to a predetermined detection rule. The access point transmits confirmation information on whether or not an event packet, including critical information on whether or not a wireless line connection between the access point and the wireless terminal is established, is transmitted, to the intrusion detection sensor, and the intrusion detection sensor examines an event packet by using the confirmation information. According to the system and method, a variety of attacks occurring on a wireless network can be effectively detected and systematically controlled.
Abstract:
A heat exchanger is provided that is capable of performing heat exchange more efficiently by using slits. The heat exchanger includes a refrigerant pipe for allowing a refrigerant to flow therethrough, at least one fin disposed such that the refrigerant pipe penetrates through the at least one fin for performing heat exchange with air passing by the at least one fin, at least one slit formed by partially cutting out the at least one fin, and at least one slit fin extending from the at least one fin adjacent to one side edge of the at least one slit for inducing turbulent flow in air flowing along a flow channel spaced a predetermined distance from the at least one fin. The width of the at least one slit is greater than or equal to ⅓ of the diameter of the refrigerant pipe. Turbulent flow is induced in air flowing through the heat exchanger by one side edge of the slit disposed downstream of the flow direction of air. Consequently, heat exchange efficiency of the heat exchanger is improved.
