Abstract:
Provided is a method for creating a mask blank that include a stop layer. The stop layer is optically compatible and process compatible with other layers included as part of the mask blanks. Such blanks may include EUV, phase-shifting, or OMOG masks. The stop layer includes molybdenum, silicon, and nitride in a proportion that allows for compatibility and aids in detection by a residual gas analyzer. Provided is also a method for the patterning of mask blanks with a stop layer, particularly the method for removing semi-transparent residue defects that may occur due to problems in prior mask creation steps. The method involves the detect of included materials with a residual gas analyzer. Provided is also a mask blank structure which incorporates the compatible stop layer.

A software based wireless infrastructure system is provided. The system has a driver that communicates with the network stack and a network interface card (NIC), a station server in communication with the station driver and an 802.1X supplicant or an 802.1X authenticator. Each NIC provides station and/or access point functionality support. The driver drops packets that have been received if the packet has not been authenticated and associated. Packets that have been fragmented or encrypted are unfragmented and decrypted. An association manager is used in conjunction with a configuration table manager to associate stations and access points via management packets. A manager receives 802.1X data packets from the packet processor and sends them up to a station server that communicates with user mode applications and an 802.1X supplicant or an 802.1X authenticator that are used to authenticate and deauthenticate stations and access points. APIs are provided to enable communication between the components.

Abstract:
The electronic device includes a body, a strap, and a strap connecting member. The strap connecting member further includes a pin, a torsion spring one end of which is connected to the pin, a receiving chamber accommodating the pin and defining an opening notch passing through the sidewall thereof, and a cover connected with the torsion spring and engaging with the receiving chamber. The strap is double-layered. The double-layered strap forms a folded end and an open end, the folded end is connected with the pin and is wrapped around the pin, and the open end is separated into two portions which pass at the opening notch and are respectively connected to the body. When the torsion spring is elastically deformed and generates a torsion force, the pin is rotated and the strap automatically shrinks in the receiving chamber under the torsion force.
