Abstract: A method of reducing the likelihood of pulseless electrical activity (PEA) after defibrillation in a subject comprises administering to a subject afflicted with fibrillation a first treatment waveform, the first treatment waveform insufficient to defibrillate the heart; and then administering to the subject a second treatment waveform that defibrillates the heart and restores organized electrical activity in the heart. The first treatment waveform reduces the likelihood of onset of PEA following the second treatment waveform, as compared to that likelihood which would be present in the absence of the first treatment waveform.

Abstract: An alternating pad consisting of transverse inflatable cells (1 and 2) alternately inflated and deflated. An internal cell (5) is provided at the outermost edges of each transverse cell (1,2). The internal cell (5) is constantly inflated at a higher pressure than the traverse cells (1, 2). The internal cell (5) is at a lower height than the cells (1,2) and preferably of a chamfered shape to provide optimum pressure relief across the whole surface of the pad. The internal cell (5) provides stable patient exit, entry or transfer from a bed or seat.

Abstract: Method and apparatus for joining a first structural element, having a passageway formed therein which opens to the exterior thereof, to a second element. A plurality of members are assembled into a joining device which is then nested inside of the passageway. The members are then moved with respect to each other to enlarge the size of the joining device so that the members engage the wall of the passageway in supporting contact therewith. The members of the enlarged joining device are then secured together into a unitary support block, with the members in supporting contact with the passageway wall. The unitary support block is connected to the second element. Unique member components, member securing means, member moving means, and the like form a new and useful apparatus.

Abstract: A computer displays nested windows representing the structure of logical and arithmetic related objects. The objects have a logical description that defines relationships between the objects including a combination of significance and precedence. The description is parsed to identify the significance and precedence of each object. Delimiters are extracted which define the significance and precedence. The relationships are displayed with nested windows on the computer display as defined by the delimiters where the relationships having a higher order of precedence are arranged in windows on top of other windows that represent lower order or precedence.

Abstract: An improved electrostatically-focused image intensifier tube, and a night vision device having such a tube, is substantially free of the spurious bright spots generally known as "PC Flash". The improved image intensifier tube includes an insulator which resists emission of electrons into the interior cavity of the tube, or a structure to capture such emitted electrons before they can fall into a microchannel plate of the tube and cause the PC Flash. A method of making such an image intensifier tube is also disclosed.

Abstract: A memory structure and related method for collecting and maintaining data descriptive of a multiplicity of interrelated process flows is disclosed. A complex memory structure includes job entities, operation entities, and process entities. Operation entities are subordinate to job entities, and process entities are subordinate to operation entities. These entities are represented by tables which are linked together to indicate their position in the hierarchy and their sequencing within a process flow. The process entities describe specific activities accomplished by an organization in achieving organizational goals. Typically, resources are either consumed or released, or both, during a process. Bill-of-resource tables are subordinate to process entities and populated with data which identify resources consumed by corresponding processes in the process flow.

Abstract: An apparatus which efficiently coordinates the association of resource and lot data in a manufacturing environment is disclosed. The apparatus includes a memory structure which associates resource and lot data only with other resource and lot data from a common dependency. A dependency is a characteristic of lots which share common resources and of resources which are shared by common lots. The memory includes nodes which describe the dependencies. The dependency nodes link to resource lists and to lot lists. The resource and lot nodes are part of resource and lot lists, respectively. Usage nodes are included to describe every use each lot makes of each resource. The usage nodes are linked to both resource nodes and lot nodes. The usage nodes are also linked together to define the order in which each lot uses its resources and the order in which each resource is used by its lots.

Abstract: A system and process for allowing virtual allocations of resources to lots to closely mimic actual allocations of resources to lots is disclosed. Virtual allocations represent planned or scheduled allocations of an organization's resources to produce various products. Actual allocations represent the actual course of events which occur while the product is being manufactured. A manufacturing interpreter interactively functions with an expert in a manufacturing environment to produce a comprehensive and accurate definition of resources utilized in a manufacturing environment. The manufacturing interpreter further allows the expert to define a comprehensive and accurate process flow description for various products. The process flow description specifies the resources, resource attribute capabilities, and order for applying resources to a single lot to produce a completed product.

Abstract: A method for translating complex process flow networks into plans or schedules for the manufacturing of products or the performance of other organizational activities is disclosed. The method maintains a time-valued list of existing commitments to resources. Allocations of these resources are made to lots during a simulation procedure which calculates a resulting plan's timing data. The method simulates higher priority lots before it simulates lower priority lots. A simulation evaluates the process flow description to obtain the relative order of consuming and releasing resources, resource attributes and related capabilities, initial minimum timing requests, and process control rules. The simulation uses the list to determine when resources may be used without impacting prior commitments of the resources. In addition, the simulation forces the allocations to conform to the process control rules.

The available resources are expressed as a multi-dimensional time ordered array of resource vertices R.sub.p [t,c,i] for each resource p, where c expresses the physical capacities associted with the p.sup.th resource, t is time and i is an integer index running from 1 to I where I is the total number of times wherein c has differing values.A logical system is provided for comparing R.sub.p and D.sub.q to determine when and how D.sub.

Abstract: A rotary envelope machine blank cutter is provided with laterally adjustable, independent frame units for each meshing set of knife rolls for changing the depth of a side cut into a blank for envelope size and style production changes. The rotational and axial meshing of hard and soft knives respective to a single knife roll set is adjusted without disturbing the roll mount of either knife. Changes in envelope length or style are accommodated by the mechanical capacity to adjust the rotation cut timing between the knife roll sets of a two-set unit and also between respective cutting units of two or more two-set units. As in the case of lateral cut adjustments, knife roll mounts are undisturbed by rotational timing adjustments. Consequently, the machine may be quickly and accurately changed for production runs of any of several envelope style and several sizes respective to each style: all adjustments being made without disturbing the knife profile mesh of any knife set.
