An electrically heated smoking system includes a shell and a replaceable mouthpiece. The shell includes an electric power supply and electric circuitry. The mouthpiece includes a liquid storage portion and a capillary wick having a first end and a second end. The first end of the wick extends into the liquid storage portion for contact with liquid therein. The mouthpiece also includes a heating element for heating the second end of the capillary wick, an air outlet, and an aerosol forming chamber between the second end of the capillary wick and the air outlet. When the shell and mouthpiece are engaged or connected, the heating element is in electrical connection with the power supply via the circuitry, and a flowpath for air is defined from at least one air inlet to the air outlet via the aerosol forming chamber. In use, liquid is transferred from the liquid storage portion towards the heating element by capillary action in the wick. Liquid at the second end of the capillary wick is vaporized by the heating element. The supersaturated vapor created, is mixed and carried in the air flow from the at least one air inlet to the aerosol forming chamber. In the aerosol forming chamber, the vapor condenses to form an aerosol, which is carried towards the air outlet.

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.

Techniques for securing electronic data and keeping the electronic data secured at all times are disclosed. According to one embodiment, a client module in a client machine is configured to provide access control to secured documents that may be located in a local store, another computer machine or somewhere over a data network. The client module includes a document-securing module configured to operate in a path through which a document being accessed is caused to pass so that the document can be examined or detected for the security nature. If the document is secured, the document-securing module obtains a user or group key to decrypt security information in the secured document for access rules therein. If a user accessing the document is determined to have the access privilege to the secured document, a file key is retrieved from the security information and a cipher module is activated to decrypt the encrypted data portion with the file key. Likewise, if a document is to be secured, the cipher module encrypts clear data from the document to create the encrypted data portion. The document-securing module integrates proper or desired security information with the encrypted data portion to produce the secured document.

Techniques for providing pervasive security to digital assets are disclosed. According to one aspect of the techniques, a server is configured to provide access control (AC) management for a user (e.g., a single user, a group of users, software agents or devices) with a need to access secured data. Within the server module, various access rules for the secured data and/or access privileges for the user can be created, updated and managed so that the user with the proper access privileges can access the secured documents if granted by the corresponding access rules in the secured data.

A system and method for providing access management to secured items through use of a plurality of server machines associated with different locations are disclosed. According to one embodiment, a local server can be dynamically reconfigured depending on a user's current location. Typically, a local server services only those users that are local to the local server. When a user moves from one location to another location, upon detecting a new location of the user who has moved from a previous location, the local server for the new location can be reconfigured to add support for the user, while at the same time, the local server for the previous location is reconfigured to remove support for the user. As a result, security is enhanced while the access management can be efficiently carried out to ensure that only one access from the user is permitted at any time across an entire organization, regardless of how many locations the organization has or what access privileges the user may be granted.

A secure software system for a portable device or computer that provides a simple interface to the device or computer and that retrieves and dynamically decrypts keys and content from a secure media while minimizing exposure of the keys and eliminating the need for manufacturers of the device or computer to create a their own system to manage these complex processes.

A multi-tube differential pressure (Delta P) testing system for testing catalyst filled tubes of tube and shell type catalytic reactors has at least one mobile test unit for movement on the upper tube sheet of a catalytic reactor. An array of test probes is mounted to the mobile test unit and is selectively positionable in sealed gas pressure communicating engagement within the upper ends of selected reactor tubes. A pressure testing gas delivery system is interconnected with the test probes and selectively communicates pressurized gas to the testing tubes at a blow-down pressure or selected test pressure determined by restricted orifices. A differential pressure measurement system measures the back-pressure resulting from application of test pressure to individual reactor tubes and having a computer receiving electronic back-pressure measurement data and producing an electronic and/or visual record correlated with a reactor tube numerical sequence and identifying the resulting back-pressure of each reactor tube of the multi-tube test. The testing system is capable of selectively electronically counting in normal sequence and in inverted sequence to accommodate test unit orientation and incorporates a separate manually positioned testing wand to accommodate tube positions of the reactor that cannot be readily accessed by one or more of the array of test probes.
