  • Publication number: 20250045932
    Abstract: A method includes determining, by a processing device based on an image of a substrate processing equipment part that forms holes, a clockwise holes spiral and an anti-clockwise holes spiral of the holes. The method further includes identifying, by the processing device, a first subset of the holes in at least one of the clockwise holes spiral or the anti-clockwise holes spiral that are at least partially clogged. A corrective action associated with the substrate processing equipment part is to be performed based on the first subset of the holes that are at least partially clogged.

  • Patent number: 12136225
    Abstract: A method includes identifying an image of a substrate processing equipment part that forms a plurality of holes. The method further includes determining, by a processing device based on the image, a corresponding neighboring angular distance of each of the plurality of holes and a corresponding area of each of the plurality of holes. The method further includes identifying, by the processing device, a first subset of the plurality of holes that are at least partially clogged based on at least one of the corresponding neighboring angular distance or the corresponding area of each of the plurality of holes. A corrective action associated with the substrate processing equipment part is to be performed based on the first subset of the plurality of holes that are at least partially clogged.

  • Patent number: 9717621
    Abstract: An adjustable cervical collar is in the form of a u-shaped base with a front joined to a pair of rearwardly extending wings. Left and right chin supports are pivotally connected at their distal ends to the distal ends to of respective wings with a chin piece connected between the upper proximal ends of the chin supports. An adjustable latch is individually coupled between each wing and the lower proximal end of the associated chin supports. Preferably the latch is in the form of 1) an arcuate slot in each wing arranged around the respective pivot axis with a track formed on opposite sides of the slot and 2) a retractable locking pin carried by each chin support and movable within the respective slot, the locking pins adapted to engage the ribs in the respective track to releasably lock the chin support to the respective wing.

  • Patent number: 7727172
    Abstract: A back brace includes a first brace member having a first connector, and a second brace member having a second connector and a coupler at two opposite sides thereof. The coupler is detachably connectable to the first connector. A first adjustment holder is affixed to one end of the first brace member and holds therein a first rod member. A second adjustment holder is affixed to one end of the second brace member and holds therein a second rod member. Two pull cords are inserted through the first adjustment holder and the second adjustment holder and run alternately back and forth over the first rod member and the second rod member to adjustably and abuttably hold the first and second brace members side by side. Two fastening members are fastened to distal ends of the pull cords and detachably connectable to the first and second connectors.
