  • Publication number: 20190244453
    Abstract: A door system is provided. The door system includes: a corridor sized to allow humans to move through the corridor, the corridor defined, at least in part by side walls, the corridor having a first end and a second end; a first door located at the first end, the first door configured to provide selective access between the corridor and a space outside of the corridor; a second door located at the second end, the second door configured to provide selective access between the corridor and a space outside of the corridor; and sensors configured to determine a direction of movement within the corridor, the sensors operatively connected to at least one of the first and second doors to cause at least one of the first and second doors to move to a closed position if any of the sensors detect a movement further than a threshold amount in an undesired direction.

  • Patent number: 5317729
    Abstract: A method for storage and retrieval of both time-oriented versions and view-oriented versions of engineering change information in which the engineering change information progresses through a set of status conditions and access to the data by different user groups is conditioned upon the status of the information. Version control software logic enables users to create versioned objects by logical key grouping of data elements. The version control logic acts upon the logical keys and special versioned attributes of these objects for the proper specification and selection of object instances during creation, update or retrieval processing. Insert and extract sequence numbers are automatically generated for both historical preservation of previous engineering change information and efficient retrieval of the currently effective designs.

  • Patent number: 5311424
    Abstract: A method and system for the definition and tracking of multiple unique product configurations for configuration management in which customer contracted views of the product are defined by applying temporary changes to the base product configuration. A product serial number effectivity is assigned to each unique customer specified product configuration and to the base product configuration in order to maintain multiple time-oriented versions of the product, thus supporting simultaneously both customer-specified and design-specified engineering changes to the base product. A product configuration identifier provides non-redundant data storage for each unique product configuration and can refer to noncontiguous ranges of product serial numbers. The configuration entry identifier in a product configuration table is used to peg detail component requirements to serially numbered products in order to correlate the product configurations as built with the product configuration as designed.

  • Patent number: 5191534
    Abstract: A system and method for controlling, monitoring and integrating engineering and manufacturing changes in a manufacturing enterprise. The status of an engineering change and the status of items affected by the engineering change are monitored by an engineering change control manager application running at a central data processing facility. The engineering change and design or modification of items affected by the change are released to one or more manufacturing locations where additional design changes may be made to accommodate local manufacturing capabilities. Each manufacturing location accepts the engineering change and the corresponding affected items when ready to proceed with implementation of the engineering change. The affected items are promoted locally at the manufacturing location to effective status which releases the affected items into production at the plant.
