Filed:

Mar 27, 2000

Appl. No.:

09/536263

Inventors:

Steven C. Crocker - Sunnyvale CA

Assignee:

Applied Materials, Inc. - Santa Clara CA

International Classification:

G01D 2100

US Classification:

116208, 116201

Abstract:

A recyclable process kit part is provided with a visible mark. After the part undergoes a cleaning process that removes deposited material therefrom, the part can be determined to be within tolerance, based on the marks visibility. More specifically, the recyclable process kit part is made of a material, and has a first surface that has a first elevation. A visual mark is formed in the first surface, and extends to a second elevation, wherein the distance between the first elevation and the second elevation is adapted such that the mark is visible until an amount of the material is removed from the part so as to make the part nearly out of tolerance.

Abstract:

Enhanced multi-level cryptographic transformations that secure electronic files are disclosed. The secured electronic files contain not only secured data but also security information. The security information includes cryptographic structure information, access rules and secrets (e. g. , keys). The cryptographic structure information explains the multi-level cryptographic transformations associated with securing or unsecuring the electronic files. The access rules and the secrets are used by the cryptographic transformations to secure the electronic files. Since the secured electronic files contain the cryptographic structure information, the particular cryptographic transformations (including their sequencing) can vary with each electronic file, if so desired. Typically, the secured electronic files are secured and managed by a file security system, such as a distributed security system.

Abstract:

In a system for providing access control management to electronic data, techniques to secure the electronic data and keep the electronic data secured at all times are disclosed. According to one embodiment, a secured file or secured document includes two parts: an attachment, referred to as a header, and an encrypted document or data portion. The header includes security information that points to or includes the access rules and a file key. The access rules facilitate restrictive access to the secured document and essentially determine who/when/how/where the secured document can be accessed. The file key is used to encrypt/decrypt the encrypted data portion. Only those who have the proper access privileges are permitted to retrieve the file key to encrypt/decrypt the encrypted data portion.

Assignee:

SecretSEAL Inc. - Menlo Park CA

International Classification:

G06F017/60

US Classification:

705/051000

Abstract:

To grant or deny access rights to a user attempting to access a protected system or secured electronic data, an access right evaluation process is carried out among all applicable policies including those embedded in the secured electronic data. In a preferred embodiment, the access right evaluation process is invoked only when a system being accessed is protected or a file being accessed is detected to be in a secured format. Further, the access right evaluation process is configured preferably to operate transparently to the user. The access right evaluation may be advantageously used in systems or applications in which devices, mediums or electronic data are secured and can be restrictively accessed by those who are authenticated and have proper access privilege.

International Classification:

H04K001/00

US Classification:

713/182000

Abstract:

Techniques for managing access to digital assets via a designated place or its sub-places are disclosed. The designated place may be a file folder, a directory, a local or remote store. The designated place is characterized by or associated with a securing module that causes all files stored in the designated place to have substantially similar security. In other words, a file to be secured can be simply dropped into the designated place and the securing module is configured to take actions to secure the file transparently in accordance with the security characteristics of the designated place. Likewise, a designated place can be set up to unsecure the secured files being deposited in the designated place, provided a user of the secured files is permitted to do so.

US Classification:

20419212

Abstract:

The present invention generally provides a vacuum processing system with a process chamber and a rotating member, such as a magnetron in a PVD chamber, disposed in a cooling cavity of the process chamber, where the rotating member includes a deflection member for deflecting cooling fluid in the cooling cavity toward interior portions of the rotating member. In one embodiment, a base plate of the rotating member defines an upper surface of the rotating member and a magnet retainer defines a lower surface of the rotating member. Magnets are mounted between the base plate and the magnet retainer. The deflection member is mounted between the magnets and can be coupled to the magnets on one or both ends. One end of the deflection member is disposed toward the outer perimeter of the magnetron and the other end of the deflection member is disposed toward the interior portions of the rotating member. As the rotating member rotates, the deflection member deflects the cooling fluid from the side of the rotating member and forces the fluid into the interior portions of the rotating member.
