Abstract: A computer information database system manages computer profile data for a set of computers. A profile group managing server coupled to the database manages the database such that there is a multiple node tree structure of groups for the set of computers in which each node is a group level and a top level is a root, based upon primary grouping criteria that correspond to selected computer profile data. Included in a database mapping table are fields that correspond to ranges of values for computer profile data of interest corresponding to primary grouping criteria including ranges that extend between a selected high and a selected low value. The ranges for any or all of the grouping criteria may be altered. The data in the database can be manipulated to produce summaries and reports of attributes of the computers in a given group.

Abstract: A user access security subsystem of a computer information database system utilizes computer grouping criteria and user type criteria to control user access to both computer profile data and system administrative features. Computer grouping criteria determine profile data access for the respective users. User type criteria determine which administrative features are accessible to the respective users, thus what administrative authority is delegated to the users. Combining computer grouping and user type criteria restricts a given user to exercising the delegated administrative authority only with respect to the particular grouping of computers to which the user has been granted access through the associated login group. To maintain access security, a given user may grant to another only those access rights that are equal to or more restrictive than the given user's rights. The subsystem enforces access restrictions by tailoring the user interface based on the associated login group and user type.

Abstract: A computer information database system manages computer profile data grouping the plurality of computers in groups that are nodes of a tree in accordance with user-specified grouping criteria that are respective values of computer profile data of interest, and manipulating the database data to produce summaries of attributes of the computers in a given group and in the groups in the subtree that has the given group as its root. The grouping criteria may be ranges of values for primary grouping criteria, particular values for primary and secondary grouping criteria, ranges of values for both primary and secondary grouping criteria, and so forth. The system uses a group mapping database table that includes profile value-to-match fields for the primary grouping criteria and, as appropriate, the secondary grouping criteria. To use ranges of values, the group mapping database table includes for each range an associated low limit profile value field and a high limit profile value field.

Abstract: A user access security subsystem of a computer information database system utilizes computer grouping criteria and user type criteria to control user access to both computer profile data and system administrative features. The computer grouping criteria determine profile data access for the respective users. The user type criteria determine which administrative features are accessible to the respective users, and thus, what administrative authority is delegated to the users. The combination of the computer grouping and the user type criteria restricts a given user to exercising the delegated administrative authority only with respect to the particular grouping of computers to which the user has been granted access through the associated login group. To maintain access security, the subsystem allows a given user to grant to another only those access rights that are equal to or more restrictive than the given users rights.

Abstract: A platform assembly designed for use in supporting a crane during the construction of a multi-story building is described. The assembly includes a platform for supporting a crane and means for fixedly attaching the platform to differing locations along the length of a structural column of such building during construction of the latter.

Abstract: Apparatus for "top-down" construction technique is described. Deck formwork assemblies for each structural concrete slab are lowered and supported from the level above the same. This application describes and claims a support arm portion of the apparatus for transmitting the load of a deck assembly to a vertical column of the building framework.

Abstract: A "top-down" construction technique is described. The deck form assemblies for each structural concrete slab are lowered and supported from the level above the same. In the preferred arrangement the form deck assemblies for each structural slab are supported by the concrete slab itself above the proposed location of the new structural slab.

Abstract: Apparatus for a "top-down" construction technique for concrete frame buildings is described. Deck formwork assemblies for each structural concrete slab diaphragm are lowered and supported from the structural slab above the same. This support is provided by suspension rods which threadably engage attachment nuts embedded in the upper structural slab.

The assembly includes a platform for supporting a crane and means for cantilevering the platform from differing locations along the length of a structural column of such building during construction of the latter.

Abstract: A dynamic lookup table device and method for storing a plurality of function values, wherein each stored function value represents a value of a function evaluated at a selected domain point of the function's domain. The device generates an input address which identifies a domain point. In response to the input address, a memory device within the lookup table device provides a lookup table entry value. The memory device includes a plurality of storage locations for storing a plurality of lookup table values. It also includes a page table storage device for mapping each input address to a corresponding storage location. Each unallocated input address is mapped to at least one shared storage location containing a default lookup table value. Each allocated input address is mapped to a corresponding storage location allocated to the input address. If the lookup table entry provided by the memory device is the default value, the lookup table device determines the value of the function at the selected domain point.

Abstract: Virtual address space for array data to be stored in a virtual memory is allocated by establishing a table that associates segments of the virtual address space with predetermined array data dimensions and maintaining a map that identifies, for each segment, which portions of the segment have been allocated to store array data. The table and map are used to identify a contiguous portion of the virtual address space for the array data to be stored.

Abstract: Fastener elements are provided for use at selected positions or openings in a composite truss system that is to be used in building construction for form work or permanent installation. The combination truss bolt drift pins proposed herein have shanks of constant cross-section for driven interfit with predrilled holes of truss elements to be joined. The shanks of the bolt pass completely through the elements being joined, and threads of lesser diameter than the shank extend outwardly from the joined elements. The fastener nuts for use with the bolts have a recess at the intended interface with the truss elements that undercut the threads thereof and that is of a size to accommodate a step shoulder of the shank thus assuring full contact of the element holes and the shank component. A drift pin extension for the bolts is of tapering contour from a larger diameter corresponding to the shank diameter to a lesser size providing easy introduction into holes intended for mating alignment.

Abstract: Handling equipment is provided to facilitate the placement, removal and repositioning of large form sections that are supported by a plurality of composite trusses. The trusses themselves are made up of chords, struts, couplers, connectors and brace components of standard sizes cooperatively interconnected to provide composite trusses that may be of various length and height. Deck panels and supports therefor are mounted on a plurality of trusses to provide a complete section of forms that is used and moved unitarily. The job site longitudinal movement of sectional forms of large size is aided through use of a plurality of tilting form glides while cross dollies provide unidirectional or multidirectional movement patterns for trusses which they support.
