Abstract: A microkeratome blade (54) that that is fabricated from a wafer (130) is disclosed. The blade (54) includes a notch (110) on its rear surface (106). During fabrication of the blade (54) from the wafer (130), a blade support tab (131) provides a structural interconnection between the wafer (130) and the blade (56). This blade support tab (131) extends within the notch (110) and merges with the blade (56). A score (132) extends across at least part of the blade support tab (131) to facilitate separation of the blade (56) from the wafer (130) by fracturing or the like. This score (132) is positioned such that the surface defined by separating the blade (56) from the wafer (130) at least generally along the score (132) is “disposed within” the notch (110) or recessed relative to a rearwardmost portion of the rear surface (106) of the blade (56).

Abstract: A method for providing a cutting tool (20) is disclosed. Multiple cutting blades (56) are fabricated from a wafer (130). This wafer (130) is disposed on a blade handle mounting fixture (224) such that a blade handle (24) may be mounted on each of the individual blades (56). A cutting edge (80) of each blade (56) is maintained in spaced relation to the fixture (224) as these blade handles (24) are being mounted. Thereafter, the wafer (130) is transferred to a blade separation fixture (300). Each blade 56 is suspended above the fixture (300). An appropriate force is transmitted to the individual blades (56) to separate the same from the wafer (130). Separation preferably occurs before the blade (56) contacts the fixture (300). Thereafter, the blade (56) in effect pivots into an inclined position where its cutting edge (80) project at least generally upwardly.

Abstract: A cutting tool (20) for a microkeratome (4) is disclosed. This cutting tool (20) includes a blade handle (24) and a separate cutting blade (56). Both the blade handle (24) and cutting blade (56) include features to register or align a cutting edge (80) of the cutting blade (56) with a microkeratome registration surface (28) of the blade handle (24). This microkeratome registration surface (28) of the blade handle (24) interfaces with a cutting tool registration surface (14) of a head assembly (10) of the microkeratome (4) on which the cutting tool (20) is installed. Therefore, the cutting edge (80) of the cutting blade (56) is registered or aligned relative to the cutting tool registration surface (14) of the head assembly (10) of the microkeratome (4).

Abstract: Various methods relating to one or more registration features (94) associated with a cutting blade (56) are disclosed. A masking layer (118) is formed on a wafer (130) and is patterned to define a plurality of mask apertures (122a-c). An anisotropic etch simultaneously forms a first cutting edge surface (72) and at least one registration surface (94) for the blade (56) via the mask apertures 122a and 122b, respectively. The anisotropic etch stops at the same crystallographic plane for both the first cutting edge surface (72) and the registration surface(s) (94). This may be used to accurately register a cutting edge (80) of the blade (56) relative to one or more structures that may be associated with the blade (56).

Abstract: A method for fabricating a cutting blade (56) from a wafer (130) is disclosed. The wafer (130) is etched to define part of the perimeter of the blade (56). This etch also defines a blade support (131) that maintains a structural interconnection between the blade (56) and the wafer (130). A score (132) is formed across at least part of the blade support tab (131). Fracturing the blade support tab (131) at least generally along the score (132) at some point in time after the completion of the etch facilitates the separation of the blade (56) from the wafer (130).

Abstract: A blade handle mounting fixture (224) is disclosed. A wafer (130) is positioned on the fixture (224). This wafer (130) includes a plurality of cutting blades (56). Blade handles (24) may be mounted on each of the various cutting blades (56) while the wafer (130) is positioned on the fixture (224). Thereafter, the wafer (130) may be removed and transferred to a blade separation fixture (300). Here the blades (56), with handles (24) having been previously mounted thereon, are separated from the wafer (130).

Abstract: A self-aligning dynamic hinge sleeve for attachment to a pitch hinge in a position that places the hinge sleeve in contact with a pitch bearing. The hinge sleeve is comprised of an inner race, a middle race and an outer race, wherein the middle race is an elastomeric material, or another soft material, that bonds the inner and outer races together and allows the inner race and outer race to rotate with respect to each other. As the pitch hinge transmits forces and moment to a pitch shaft, the dynamic hinge sleeve aligns with a pitch bearing secured onto the pitch shaft. This results in a self-aligning pitch bearing rotor that significantly reduces the level of peak that loads upon a bearing and thereby permits the use of self-lubricating bearings in a rotor.

Abstract: In a storage system comprising an array of storage devices, including a processor and memory, a plurality of logical tracks are organized on the storage devices in segments comprising columns striped across the storage devices. A system and method are provided for storing logical tracks in the storage devices. Sequentially logically related logical tracks are stored together in neighborhoods. Logical tracks of the same neighborhood destaged at the same time are assigned to a single open segment with other logical tracks of the same neighborhood type. The time at which open segments are designated as closed segments to be written to the storage devices is based on performance, disk utilization and memory utilization criteria. Logical tracks are never split between segment columns. Also, attempts are made not to split a neighborhood of logical tracks being destaged together between segment columns.

Abstract: A storage library includes a first robotic mechanism having an energy coupler and a second robotic mechanism having an energy coupler. The storage library further includes tracks disposed adjacent to media object storage cells for enabling access to each of the media object storage cells, and powered rails associated with the tracks for providing energy. The first robotic mechanism is movable toward the second robotic mechanism to enable the energy coupler of the first robotic mechanism to couple with the energy coupler of the second robotic mechanism to transfer energy from the first robotic mechanism to the second robotic mechanism. The energy couplers of the first and second robotic mechanisms couple together to transfer energy from the powered rails to the second robotic mechanism. The energy couplers of the first and second robotic mechanisms couple together to transfer energy between on-board energy sources.

Abstract: A data processing system dynamically balances allocation of storage areas in a shared coupling facility that is devoted to storage of directory entries and data blocks. Each directory entry includes information regarding the validity of a data block that is locally stored by one or more processor modules in the data processing system. The system includes a coupling facility having a cache memory wherein a first portion is allocated to storage of data blocks and a second portion is allocated to storage of directory entries. Each directory entry, associated with a data block, indicates the validity or invalidity of data contained in a copy of the data block maintained by a connected computer module in its local memory. Each computer module, upon requiring a first data block and determining that (i) the first data block is present in its local memory (i.e., a buffer "hit"), but (ii) is not marked valid and (iii) is not present in the coupling facility (i.e.

Abstract: A system and method are provided for managing persistent and non-persistent data in a log structured disk array. In a log structured array, data are first collected in a log stored in a buffer. When the buffer is full, the data are written to a disk drive. Persistent data are continually accessed over a long period of time such that, most disk activity is associated with persistent data. Preferably, the persistent data are stored in the part of the disk where access times are minimal (active region), such as in the middle cylinders of a disk. When writing data (including during garbage collection procedure) persistent data is written to the active region and non-persistent data is written to the other regions (inactive region). The persistence of the data is monitored. Persistent data is migrated to the active region and non-persistent is migrated to the inactive region.
