Abstract:
An apparatus, system, and method are disclosed for detecting mismatches in a mirror volume. A receive module receives a start indicator from a primary storage system. The start indicator includes a starting location of a first block to be modified on a track in a secondary storage system. The first block corresponds to an identically located first block of a modified record in the primary storage system. The tracks the first blocks on the primary and secondary storage systems each comprise irregular count key data ("CKD") tracks. A compare module compares the first block location indicated by the start indicator with block locations listed in track metadata. The track metadata describes user records on the irregular CKD tracks of the secondary storage system. An alert module generates an alert in response to the first block not aligning with a beginning block of a record on the secondary storage system.
Abstract:
Provided are a method, system, and article of manufacture for copying storage. Data sent from a first storage unit is synchronously copied at a second storage unit. The copied data is sent asynchronously from the second storage unit to a third storage unit.
Abstract:
Disclosed is a technique for reducing an amount of data transferred. A first indicator is maintained for each source block of data to indicate whether the source block of data has been updated in source storage since the source block of data was last transferred to target storage. A second indicator is maintained for each target block of data in target storage to indicate whether the target block of data has been updated in target storage since the target block of data was overwritten by a corresponding source block of data. When transferring data from the source storage to the target storage, each source block of data for which a first indicator has been set to indicate that the source block of data has been updated is transferred and each source block of data that corresponds to a target block of data for which a second indicator has been set to indicate that the target block of data has been updated is transferred.
Abstract:
There is disclosed improved apparatus and methods for detection of shape, size and intrinsic fluorescence properties of a fluid borne particle wherein the apparatus comprises a laser, two light sources, two detectors, and optionally a third detector. The apparatus is particularly suitable for detection of airbone biological particles.

1280303 Clips S W BURCHETT 23 Sept 1969 [30 Sept 1968] 46879/69 Heading E2B A one piece fastener for gripping thin flexible material comprises partly overlapping portions provided with complementary tongue and slot retaining means for fastening the overlapping section together. The fastener has an opening 20 and two overlapping pivoting flap parts 3, 4 flexibly connected to the body, the part 3 having an offset tongue 11 which is passed through a T-shaped slot in the part 4 to retain material passed over the tongue. In a modification the part 4 has a pivoting flap in the slot and in another modfication the pivoting flap parts are duplicated. In a further modification the part with the slot is attached by a narrow strip to the upper portion of the body. (For Figure see next column)

1,138,104. Devices for marking contents of safe, safes. K. S. WARREN [L. J. FISHER]. 31 May, 1967, No. 25179/67. Headings E1A and E2X. A container 10 for valuables 20 includes a storage compartment 22 and a reservoir 36, 38 of a marking agent, the container being formed on its exterior with outer and inner electrically conductive shells (72), (76), (80) Fig. 3 (not. shown) separated by an electrically-insulating layer (74), (78) and including means to maintain the shells at different relative electrical potentials and means to discharge the marking agent into the storage compartment when the shells become electrically conductive. As shown, the container is provided with a hinged lid 14 securable to the body 12 of the container by a key-operated lock 24 and a staple 28 and hasp 30 and is separated from the storage compartment by a cover plate 18. The reservoir consists of a glass phial 36 containing an indelible liquid dye and a cardboard cartridge 38 of indelible dye in powder form. Electrical detonators are associated with the phial and the cartridge. The cover plate 18 includes vents 42, to allow the dyes released to enter the storage compartment, and includes a cover 44 for a battery housing. Switches 48 and 56 on the body 12 are operated by the lid as the latter is closed and a switch 62 on the lid cooperates with the lock 24. The walls 'of the box comprise a layer (72) of steel, a layer (74) of a plastics material, a layer (76) of aluminium, a layer (78) of plastics material, a layer (80) of aluminium and a layer (82) of plastics material. The arrangement is such that switches 48 and 56 are open when the box is closed and the switch 62 is closed when the lock 24 is operative. When the box is closed and locked, electrical connection between the shell (76) and either of the shells (72) or (78) or prising of the lid to close any of the switches 48, 56 detonates the phial 36 and the cartridge 38 to release the dyes into the compartment 22 through the vents 42, some of the powdered dye also escaping through the space between the body and the lid. For transport purposes without the dyes being discharged, the lid is secured by a padlock through the hasp and staple and the lock 24 is not operated. The invention is applicable to wall safes and strongrooms,
Abstract:
A sensor for detecting changes in spinal tissue is disclosed. The implantable sensor or surgical instrument includes a sensing element adapted for detecting indicators of tissue health. The sensor is configured for transmitting the tissue data outside of the body. Further a system and method are provided to utilize the sensed tissue properties to treat the patient's condition.
Abstract:
Caches are associated with processors, such multiple caches may be associated with multiple processors. This association may be different for different main memory address ranges. The techniques of the invention are flexible, as a system designer can choose how the caches are associated with processors and main memory banks, and the association between caches, processors, and main memory banks may be changed while the multiprocessor system is operating. Cache coherence may or may not be maintained. An effective address in an illustrative embodiment comprises an interest group and an associated address. The interest group is an index into a cache vector table and an entry into the cache vector table and the associated address is used to select one of the caches. This selection can be pseudo-random. Alternatively, in some applications, the cache vector table may be eliminated, with the interest group directly encoding the subset of caches to use.
