An apparatus for selectively extracting components of an input signal comprises a plurality of microphones for detecting an audio signal in a plurality of spaced locations. A plurality of signal samplers sample each spaced version of the audio signal. A microphone pattern processor derives a reference signal, a null signal and a core signal from the sampled signals. An adjustment frequency spectrum generator coupled to the null and reference signals generates an adjustment frequency spectrum signal that is applied to the core signal. An audio signal regenerator provides an output audio signal from the adjusted core signal. The apparatus can be used in a wireless device to pick up a speaker's voice in a noisy environment.

Systems and methods for designing systems that include computer applications hosted on hosting environments are disclosed.

Multi-level file digests for electronic files are disclosed. A top level digest represents a single digest for the associated electronic file. Lower level digests represent digests for portions of the associated electronic file. The top level digest is derived from the lower level digests. The top level digest is useful for facilitating rapid comparison to determine whether electronic files are the same. In one embodiment, electronic files are encrypted with a block encryption scheme, and digests are efficiently calculated and stored on a block-by-block basis. Advantageously, when modifications to an encrypted electronic file occurs, only those modified blocks need to be processed to undergo decryption and re-encryption to determine the appropriate digest.

The invention discloses an IMSI protection method based on pseudonym, belonging to the field of communication safety. The method comprises: in an initial network accessing stage for a user, the user sends IMSI to HLR for authentication; after authentication, a pseudonym is generated for the user and is recorded into a database; then, according to the user pseudonym, HLR generates an authentication vector and authenticates the user by VLR; finally HLR sends a user pseudonym field in the user pseudonym to the user; and the user reconstructs and records the user pseudonym. In a secondary networkaccessing stage for the user, the user sends the user pseudonym to the HLR for authentication; if a database does not have the user pseudonym, authentication is reported to fail, otherwise, HLR generates a new user pseudonym and updates the database; then, the user is authenticated like initial network accessing; finally, HLR sends the user pseudonym field in the user pseudonym which is newly generated to the user; and the user reconstructs and records the user pseudonym. The method greatly improves the safety of IMSI, and the system is convenient to update.

A wafer container utilizes a rigid polymer tubular tower with slots and a “getter” therein for absorbing and filtering moisture and vapors within the wafer container. The tower preferably utilizes a purge grommet at the base of the container and may have a check valve therein to control the flow direction of gas (including air) into and out of the container and with respect to the tower. The tower is sealingly connected with the grommet. The tower may have a getter media piece rolled in an elongate circular fashion forming or shaped as a tube and disposed within the tower and may have axially extending. The media can provide active and/or passive filtration as well as having capabilities to be recharged. Front opening wafer containers for 300 mm sized wafers generally have a pair of recesses on each of the left and right side in the inside rear of the container portions. These recesses are preferably utilized for elongate towers, such towers extending substantially from a bottom wafer position to a top wafer position. In alternative embodiment, a tubular shape of getter material is exposed within the front opening container without containment of the getter other than at the ends. The tubular getter form is preferably supported at discrete locations to maximize exposure to the internal container environment. A blocker member can selectively close the apertures. An elastomeric cap can facilitate securement of the tubular component in the container portion.

A cellular communication system comprises a core network, a first access network not supporting circuit switched services and a second access network supporting circuit switched services. A user equipment detects that an application using circuit switched communication is initiated and accordingly initiates a reselection from the first to the second access network. The user equipment transmits a location update message to a circuit switch mobile switching centre of the core network which in response notifies a mobility management entity for the first access network that the access network reselection has been initiated. In response to the notification the mobility management entity initiates a change of a routing association from being with the first access network to being with the second access network. The invention may e.g. allow improved circuit switched fallback for a 3^rd Generation Partnership Project cellular communication system comprising an access network supporting only packet switched services.

Through content control gateway (CCG), computer communicates to inner network server (INS). CCG is setup in front of INS. Computer inside inner network includes working software of 'security desktop'. Encrypted tunnel is adopted between computer and CCG. Cipher mode is used for local computer to save files. Cipher key is setup at local computer. Based on working software of 'security desktop', working system uses cipher mode to save files in local computer, and carry out network transmission. When trying to access INS, terminal computer must log on CCG first. Based on authorization of terminal and condition to activate 'security desktop', CCG determines whether to execute accessing proxy. If 'security desktop' is not activated, then access from the terminal is refused, or 'security desktop' is forced to be turned to on to continue accessing. Through 'security desktop', terminal can only access CCG, and cannot access other network addresses.
