摘要： A control device including a switch with a ferromagnetic armature moving between a first position and a second position. The armature actuates a plunger that causes the switch to snap from an open position to a closed position. An energy-storing member may be positioned adjacent the ferromagnetic armature, the energy-storing member moving a magnet between an attracting position and a non-attracting position based on a temperature of an environment surrounding the energy-storing member. When the energy-storing member positions the magnet in the attracting position, the magnet causes the armature to snap from the first position to the second position, thereby actuating the plunger and causing the switch to snap from the open position to the closed position. A ferromagnetic backstop may also be positioned adjacent the magnet and coupled to the energy-storing member to hold the magnet and the energy-storing member in the non-attracting position.

摘要： A printer is described. The printer includes a CPU, a DMA controller and an internal memory. The CPU and the DMA controller are each connected to a first memory bus. The internal memory is connected to a second memory bus. The printer further included an address translation unit connected to both the first and the second memory bus. The address translation operates to receive virtual addresses from both the CPU and the DMA controller over the first memory bus and translates these virtual addresses into physical addresses. The address translation unit transmits the physical addresses to the memory over the second memory bus.

摘要： A convertible two-mode pressure regulator in which a main valve regulates fluid flow between an inlet and an outlet in response to a control pressure produced by a mechanically operated regulator valve, the control pressure depending on the outlet pressure and the force applied by a compression spring to a diaphragm carrying a regulator valve closure element. Compression of the regulator spring is controlled by a mechanical lever assembly and a shaft assembly which is selectively positionable by a selector knob to obtain higher or lower regulator spring force. Adjustable stops provide for individual adjustment of low and high outlet pressures for each of two pressure ranges.

摘要： A disk storage control system includes dual controllers having real-time, synchronous, mirrored memory therebetween to provide immediate, accurate, and reliable failover in the event of controller failure. Non-volatile random access memory provides retention of data during a loss of power and during the manipulation of hardware for purposes of repair. A communication path is established within the mirrored memory between the controllers to monitor and coordinate their activities. The state of the mirrored memory is continuously monitored for accuracy of the mirror and failure detection. Concurrent and ready access by a host computer to the same disk storage control data set from each controller is provided without need for extra manipulation or extra direct memory access (DMA) activity to satisfy host requests. Accordingly, either controller can provide immediate and reliable failover control for the disk storage system. Furthermore, either controller can be hot swapped in the event of failure without the need for preparatory intervention. Finally, a secondary controller can recover a mirror image from a failed stand alone controller memory to provide continued operations thereby so long as the mirrored memory was not the failing component.

摘要： The methods concern fully utilizing storage capacity in a heterogenous hierarchic disk array having storage disks of differing capacities. The disks are segmented into multiple regions. One method links non-contiguous regions from individual storage disks to form RAID areas. The RAID areas are mapped into a virtual storage space that provides a view of the physical storage space as a single storage volume. Data is then stored in these RAID areas according to different redundancy criteria, such as RAID Level 1 and RAID Level 5. A second method fully utilizes of storage capacity by configuring the heterogeneous disk array to employ a minimum of two equal-sized storage disks that have larger capacity than other individual storage disks in the disk array. The contiguous regions across the multiple disks are then grouped together to form the RAID areas.

摘要： A hierarchic disk array data storage system has multiple storage disks that define a physical storage space and a RAID management system that maps the physical storage space into two virtual storage spaces. The RAID-level virtual storage space presents the physical storage space as mirror and parity RAID areas where the mirror RAID areas contain mirror allocation blocks to store data according to RAID Level 1 and the parity RAID areas contain parity allocation blocks to store data according to RAID Level 5. The application-level virtual storage space presents the physical storage space as multiple virtual blocks. The RAID management system migrates data between the mirror and parity RAID areas to optimize performance and reliability. To ensure that sufficient space is retained for this migration, the RAID management system limits the number of virtual blocks that are allocated in the mirror RAID areas. The maximum number of virtual blocks in mirror RAID areas is dynamically computed based upon a function of the physical capacity of the storage disks, the number of storage disks, and the allocated capacity at the time of each storage request from the user.

摘要： A hierarchic disk array data storage system has a disk array with multiple storage disks and a disk array controller which coordinates data transfer to and from the disks. The storage disks define a physical storage space. A RAID management system maps a RAID-level virtual storage space onto the physical storage space. The RAID-level virtual storage space presents the physical storage space as multiple RAID areas. The RAID areas include mirror RAID areas which contain mirror allocation blocks to store data according to mirror redundancy and parity RAID areas which contain parity allocation blocks to store data according to parity redundancy. The RAID management system dynamically migrates data between the mirror and parity RAID areas in a manner which optimizes performance and data reliability. As new storage requests are made, the RAID management system evaluates the existing storage conditions and computes a total virtual capacity that is available to the user given a disk array configuration. A total virtual capacity can be calculated without including the capacity of any given storage disk in the disk array data storage system. The total virtual capacity calculation is used to support hot spare space reservation, disk removal, rebuild of a failed disk, and to prevent over-commitment of storage to user data.

摘要： A data memory system has a hierarchic disk array of multiple disks, a disk array controller for coordinating data transfer to and from the disks, and a RAID management system for mapping two different RAID areas onto the disks. The RAID management system stores data in one of the RAID areas according to mirror redundancy, and stores data in the other RAID area according to parity redundancy. The RAID management system then shifts or migrates data between the mirror and parity RAID areas on the disks in accordance with a predefined performance protocol, such as data access recency or access frequency. The data memory system also includes a memory map store embodied as a non-volatile RAM. The memory map store provides persistent storage of the virtual mapping information used by the RAID management system to map the first and second RAID areas onto the disks within the disk array. The RAID management system updates the memory map store with new mapping information each time data is migrated between mirror and parity RAID areas.
