摘要:
An addressing method and computer system for sharing a large memory address space using address space within an operating system's virtual address space. The system provides sharing the SSB over many processes without the disadvantages associated with process based global sections. For instance, the novel system does not require that each process maintain its own dedicated page table entries (PTEs) in order to access the SSB thereby requiring less operating system virtual memory to maintain the PTE data structures. The system uses a process to switch to kernel mode, then identifies those sections of the operating system virtual memory space that are not being used; in some cases the unused address space can be 1.5-1.8 gigabytes in size. The unused address space is linked together to form the SSB. The system alters the privileges of the PTEs corresponding to the SSB so that user mode processes can access this usually protected operating system virtual memory space. The result is a statically mapped large memory address buffer (SSB) that can be immediately shared by all processes within the computer system while consuming only a single statically mapped PTE which all processes can use. In one example, 500 processes mapping to a 2 gigabyte SSB requires only 2 megabytes of memory storage for the corresponding PTEs, assuming conventional memory page sizes. In one example, the SSBs are allocated from a system space virtual memory map which is 2 gigabytes in size in a 32-bit VMS operating system.

A consumable component for a thermal processing torch is provided. The consumable component includes a consumable component body and a signal device located on or within the consumable component body for transmitting a signal associated with the consumable component. The signal can be independent of a detectable physical characteristic of the consumable component.

摘要:
A modular blind transport system for a window blind application. The complete system may be assembled from a relatively small number of individual modules to obtain working systems for a very wide range of applications, including especially a category of counterbalanced blinds wherein a relatively small external input force may be used to raise or lower the blind, and/or to open or close the blind.

A drying system (100) for use in drying out a water-damaged structure includes a blower (105) for providing outside air to the water damaged structure. An indirectly fired furnace (101) is used for heating the outside air prior to its introduction into the water-damaged structure. An exhaust blower (114) removes humid air from the water-damaged building, and one or more remote temperature and humidity sensors (117) are used for controlling the furnace air temperature and supply blower volume. An air intake filter box (111) is used for adding make-up air to recirculated building air and promoting cooling within accompanying trailer. A differential air pressure transmitter (118) controls the volume of moist air removed from the water damaged building to an optimal rate.
