  • Patent number: 11971599
    Abstract: A sealed terminal has a housing, a cover, a splice tray, an adapter plate, and a splice chip. The cover is connected to the housing to close an interior compartment and has input ports for receiving one or more cables and an output adapter module having a plurality of distribution ports. The splice tray is positioned in the interior compartment and has one or more cable retainers configured to route the one or more cables within the interior compartment. The adapter plate is connected to the splice tray and has a plurality of adapters for connecting the one or more cables to the distribution ports. The splice chip is connected to the splice tray and has a plurality of slots for receiving and routing the one or more cables. The housing includes a radiused wall for routing the cables within the interior compartment without bending the cables.

  • Patent number: 4630306
    Abstract: In automatically checking circuit boards by raster scanning, it is useful to code and store conductor boundaries for later analysis. Coding time can be reduced by storing an identification of a chain of boundary segments in one of two arrays each time a boundary is detected in a scan line, the identification being stored at an address corresponding to the position of the segment detected. At the same time signals describing the segment are stored in another store at an address related to the identification. When in the next scan line a boundary segment is detected, an address corresponding to its position is used to address the said array and if an identification is found, the new segment is stored in the other store as part of the chain identified. In order to reduce the size of the other store signals describing segments are not stored in areas allocated to chains but in the next vacant location and a RAM stores links between segments.

  • Patent number: 4298808
    Abstract: A method for indicating a defect in a workpiece, comprises applying a continuously variable signal derived from inspection of the workpiece and including a pulse component representative of the defect to a bank of filters having different frequency transmission characteristics respectively representative of defects of different type so that the filter corresponding most closely to the defect inspected, produces a relatively greater output and provides an indication of defect type.
