  • Method and apparatus for on-line monitoring of the operation of a complex non-linear process control system
    Patent number: 4552718
    Abstract: The operation of a nuclear fueled, electric power generating unit is monitored by utilizing decision tree analysis of selected system parameters to generate a representation of the real time system status. Current system status is presented to the operator either in the form of conclusory indications, such as verbal statements, representative of system status, or in the form of a visual display of the entire decision tree including indications of the path through the tree representative of current conditions. In either case, indications of off-normal conditions are accompanied by directions as to appropriate action to be taken, either by the operator or the automatic control system, to steer the system toward more acceptable conditions. In addition, the status indications are prioritized to indicate the seriousness of the off-normal conditions and to direct the sequence of corrective action to be taken when multiple off-normal conditions exist.

  • Artificial tree with LED-based lighting systems
    Patent number: 10982828
    Abstract: A multi-sectional artificial tree with a tree lighting system. The tree includes a DC power converter, and lower and upper tree sections. Each tree section includes a tree frame with groups of branches and light sets in a ratio of one light set per branch. The thin, single-conductor wires of each light set are affixed only to a single branch to prevent bending and breaking. Each group of branches and light sets is positioned at a particular height on the trunk of the tree. An upper tree section includes fewer branches per group, as compared to a lower section, and thus includes fewer light sets per group. The light sets are wired in series from branch-to-branch, though the number of light sets per group varies from section to section. Consequently, a resistive load is used in the upper tree section to adjust a voltage applied to individual light sets.
