250311, 250310, 250306, 250307, 2504911

Abstract:

An apparatus and method for scanning the surface of a specimen is disclosed for defect inspection purposes. Scanning Electron Microscope (SEM) is used to scan the surface of a specimen. The scanning method employed by the SEM comprises the steps of: generating a particle beam from a particle beam emitter, and scanning the surface of the specimen by deflecting the particle beam at an angle with respect to the surface of the specimen, wherein the particle beam traverses an angle that is not parallel or perpendicular to the orientation of the specimen. The specimen being scanned is a semiconductor wafer or a photo mask.

US Classification:

3703102, 370229, 3702301, 370400, 455453

Abstract:

A centralized wireless LAN load balancing mechanism is described herein. In one embodiment, in response to a request for entering a wireless network from a wireless station and forwarded from multiple access points (APs) of the wireless network, a network access device coupled to the multiple APs determines a load for each of the APs. The network access device then selects one of the APs based on the determined loads of the APs and instructs the selected AP to associate with the wireless station. The network access device further instructs the remaining APs to reject the request. Other methods and apparatuses are also described.

International Classification:

H04L 12/28

US Classification:

370401, 370338, 4554221

Abstract:

According to embodiments of the invention, a first wireless access point discovers a second wireless access point, the first wireless access point tunes its radio and privacy settings, without user input, based upon parameters automatically exchanged in response to the discovery of the second wireless access point, and a secure direct wireless connection is established between the first and second wireless access points using the radio and privacy settings.

Abstract:

A method is disclosed for providing security to a client-to-client communication. The method includes authenticating a first client and a second client with an access point device, transmitting the packet to the security device and modifying a destination media access control (MAC) address of a packet from the first client to a MAC address of a security device for a first network. The packet contains a destination internet protocol (IP) address of the second client. The access point device and the first and second clients belong to the first network. The security device is located between the first network and a second network.
