摘要： A storage system is disclosed including storage devices configured to store data, and a logical storage volume coupled to the storage devices and configured to store a subset of the data as segments. The storage system also includes a controller including a cache and memory. The memory is configured to include records such that each record corresponds with a segment in the logical storage volume and each record includes information regarding data stored in the corresponding segment. The controller is configured to access the records in response to a cache miss of the cache to determine if requested data from the cache miss is stored and ready for access in the logical storage volume. The controller is also configured to update the subset of data stored in the segments as a function of cache misses.

摘要： A system and method for producing spectrally segmented images of object fields. In one embodiment the system includes an optical system that focuses light received from an object field along a focal plane with a field stop positioned within the optical system that has plural apertures for selectively transmitting the light from the object field. A diffractive element is positioned within the optical system to spectrally spread, along the focal plane, the light transmitted through the apertures. The apertures can be parallel slots or geometrically arranges holes. The plural apertures are spaced such that the spectrally spread light transmitted through any given aperture and incident upon the focal plane does not overlap on the focal plane with the light transmitted through any other aperture. The diffractive element may spread light across one or more directions. In one embodiment, a processor is coupled to a plurality of pixels in a focal plane array. A memory for storing image data organized as a hyper-spectral cube.

摘要： A method for measuring acceleration uses an accelerometer apparatus having an optically transparent, stress-birefringent material, a source of polarized light positioned to direct a polarized beam of light into the optically transparent, stress-birefringent material, and a detector system positioned to detect an output beam from the optically transparent, stress-birefringent material. The accelerometer apparatus is accelerated, and the acceleration of the accelerometer apparatus is simultaneously determined from a measurement of stress-induced optical birefringence in the optically transparent, stress-birefringent material.

摘要： A method for automatically remapping a disk after receiving a bad sector indication without requiring system operator intervention, initiation of a diagnostic program or system down time. When the disk controller receives the error and mirroring or parity operation is activated, a remap routine is initiated. The routine finds the bad sector in the request, builds a good track of data and stores this good track of data in a reserved area on all the disk units on the controller. The data in the reserved area is then read, and if successful, the track having the bad sector is remapped to remove the bad sector from use. The saved data is then rewritten to the track, thus restoring the disk unit to full operation. A flag is set during the process so that should power fail the process can be restarted.

摘要： A compensated radome is provided, comprising an inner layer of a negative index of refraction material, often referred to as a “metamaterial”, and an outer layer of a positive index of refraction material. The thickness of the two materials and their respective refractive indices are adjusted so that a beam of light passing through the radome is effectively not refracted. The metamaterial-compensated radomes solve the bore sight angle problem with a minimum of complexity.

摘要： A method and apparatus which indicates the physical location of one or more peripheral devices. A system operator uses an input device to select an icon that is displayed on a display device. The icon represents a single peripheral device or a group of peripheral devices among a plurality of peripheral devices. For example, an icon may represent a disk drive, a group of disk drives disposed within a storage unit, an array of disk drives, an array of disk drives disposed within one or more storage units, etc. After the system operator selects the icon, an indicator light associated with each of the one or more peripheral devices represented by the icon illuminates to identify the physical location of the selected peripheral device or devices. Other peripheral devices are contemplated, such as a bank of modems, floppy drives, CD-ROM drives, etc.

摘要： A new and improved apparatus and method for rebuilding a replacement disk of a fault tolerant, mass storage drive array subsystem of a computer system. The method calls for a microprocessor to check a stripe for consistency. If the stripe is inconsistent, the microprocessor rebuilds a predetermined number of stripes. If the checked stripe is consistent, then the microprocessor checks a next stripe and repeats the above-described process. Because the drive array subsystem receives both system requests and rebuild requests, the present invention allows a user to select the drive array subsystem's priority in processing system requests versus rebuild requests, thereby allowing greater system access to the drive array subsystem during peak times of system requests.
