Abstract: A technique for performing ray tracing operations is provided. The technique includes processing small bounding box nodes in a box intersection test circuit to generate intersection test results for the small bounding box nodes; and processing large bounding box nodes in the box intersection test circuit to generate intersection test results for the large bounding box nodes.

Abstract: An example apparatus includes a sensor to detect a lateral edge of a door curtain within a guide of a door, and a controller to identify when the door curtain transitions from an operational state to a breakaway state based on a signal from the sensor, the operational state corresponding to when the lateral edge of the door curtain is enclosed by the guide as the door curtain moves between open and closed positions, and the breakaway state corresponding to when a portion of the lateral edge of the door curtain below an upper end of the guide breaks away from the guide.

Abstract: Methods and apparatus to wirelessly interlock doors are disclosed. A door system includes a user interface to receive interlock configuration data input from a user, the interlock configuration data to define an interlock condition to be satisfied before a first door is to undergo an operation, the interlock condition associated with a current state of a second door. The door system includes a first wireless transceiver to receive a signal from a second wireless transceiver associated with a second door. The method includes a door operation controller to at least one of (1) implement the operation of the first door in response to a request when the current state of the second door satisfies the interlock condition, (2) ignore the request, or (3) not execute the operation of the first door in response to the request when the current state of the second door does not satisfy the interlock condition.
