A method and system for distributing and enforcing security policies is provided. A firewall agent executing at a host computer system that is to be protected receives security policies for the enforcement engines responsible for enforcing the security policies on the host computer system. A security policy has rules that each provide a condition and action to be performed when the condition is satisfied. A rule also has a rule type that is used by the distribution system to identify the security components that are responsible for enforcing the rules. To distribute the security policies that have been received at a host computer system, the firewall agent identifies to which enforcement engine a rule applies based in part on rule type. The firewall agent then distributes the rule to the identified enforcement engine, which then enforces the rule.

The present invention relates a method of supplying fuel to a fuel cell, which comprises steps of: feeding a specific amount of a fuel into a fuel cell; obtaining a second characteristic value at a specific time point; detecting and measuring a character of the fuel cell at a time interval before the specific time point for obtaining a second characteristic value; comparing the second characteristic value to the first characteristic value for enabling the fuel to be fed into the fuel cell while the second characteristic value is smaller that the first characteristic value. By the aforesaid method, the supplying of fuel to the fuel cell can be effectively controlled for optimizing the performance of the fuel cell without the use of fuel sensor required thereby and thus reducing the cost and complexity of manufacturing the fuel cell system.

An apparatus for image rotation. The apparatus includes a first memory, a frame buffer, a rendering module, a rotation object determination module, a rotation module, and a replacing module. The rendering module renders a second image according to second image data. The rotation object determination module detects a variation between the first image and the second image to identify a first image variation object of the first image, a second image variation object of the second image, and a rotated first image variation object of the first rotation image. The rotation module rotates the second image variation object as a second image rotation object. The replacing module retains the first rotation image except the rotated first image variation object and replaces the rotated first image object of the first rotation image with the second image rotation object to form a rotated second image.

An opportunistic directory cache and method of usage reduce the number of calls between a client and server for file information, reducing the wastage of network resources and server resources. The expirable directory cache can be refreshed any time an appropriate directory enumeration call is made to the server, and is capable of being partially rather than completely invalidated in response to an indication that the file information of a file listed in the cache has or will change. If the affected file is identifiable, the entry in the cache for that file is invalidated, i.e. it is no longer useful for serving file information. If the affected file is not identifiable, then a first character projection of the file name is invalidated in the cache. In this manner, the directory cache is maintained with minimum resources and is persisted to the greatest extent possible, increasing its likelihood of usefulness.

The present invention provides a novel client side caching (CSC) infrastructure that supports transition states at the directory level to facilitate a seamless operation across connectivity states between client and remote server. More specifically, persistent caching is performed to safeguard the user (e.g., client) and/or the client applications across connectivity interruptions and/or bandwidth changes. This is accomplished in part by caching to a client data store the desirable file(s) together with the appropriate file access parameters. Moreover, the client maintains access to cached files during periods of disconnect. Furthermore, portions of a path can be offline while other portions upstream can remain online. CSC operates on the logical path which cooperates with DFS which operates on the physical path to keep track of files cached, accessed and changes in the directories. In addition, truth on the client is facilitated whether or not a conflict of file copies exists.

The present invention is directed at a system and method for managing and evicting objects stored in a cache. The invention provides a mechanism for determining which objects to evict based on a weight that is calculated for each object stored in the cache. The weight is determined by at least two factors, including file size, file type, primary user, last access time, and the like, and by the relative importance of each of the factors. The weight for each object may be determined autonomously and/or may be determined upon a trigger event. The factors and their relative importance may be obtained from a policy applicable to one or several computers.

This disclosure relates to recreational vehicles (RV's) and discloses an expandable folding recreational vehicle (RV) that includes a chassis and a carriage house mounted on the chassis. The carriage house includes: a living room configured for a resident to perform activities; a bedroom configured for the resident to rest or sleep; a kitchen configured for the resident to prepare food and cook; a bathroom configured for the resident to urinate, defecate, bathe, or wash up; an electrical system operatively connected with the living room, the bedroom, the kitchen, and the bathroom; and a first and a second drive assembly configured for contracting or expanding the living room and the bedroom. The kitchen and the bathroom are arranged adjacent to each other on the chassis, and the living room and the bedroom are contractible and disposed on both sides of the chassis, respectively.

Fluorescence methods and systems that use an optical agent for measuring the pH of a fluid. The optical agent is a photonic nanostructure having a supramolecular structure, such as a shell cross-linked micelle that incorporates at least one linking group that includes one or more photoactive moieties.
