摘要： A computer-implemented system for designing a fire protection and/or piping system comprising a personal computer for loading programs into dynamic memory and storing data on a static memory device, means for providing user input, and program files comprising a process algorithm, traversing algorithm, and tagging algorithm. The process algorithm performs data validation, error checking and error resolution, saves data to a start point inserted by a user, pulls layer details into programming variables, applies processing logic to the system, and comprises a main pipes algorithm and a branch resizing algorithm. The traversing algorithm travels the system and presents objects to the process, main pipes and branch resizing algorithms in a logical order. The tagging algorithm attaches to each pipe in the system a tag with property set data pulled into and displayed in the tag. A method of using the foregoing system to design a fire protection and/or piping system.

摘要： A list of data structures (e.g., inodes) can be accessed, and the data structures in the list can be examined. If a data structure is examined, a counter value associated with the data structure is changed to a generation number that is associated with the examination. Subsequently, the counter values can be used to identify unreferenced data structures. More specifically, the counter value for an unreferenced data structure will be different from the generation number for the most recently performed examination.

For example, various embodiments of the present invention provide methods for modifying magnetic information transfer. The methods include retrieving magnetically represented data from a storage medium, and converting the magnetically represented data to a series of data samples.
