Abstract: A method for increasing dynamic range of a time-delay integration (TDI) image includes assigning a value N to a line-number setting and generating each line of the TDI image by (i) selecting N lines from N corresponding images of an image sequence, and (ii) integrating the N lines. The brightness of the TDI image is evaluated, after which the line-number setting is updated to a new value. In another method, the value of a TDI pixel is initialized to the value of a corresponding pixel in a first image of the image sequence. While the TDI pixel value is less than a ceiling, a contribution is added to the TDI pixel value, the contribution being based on the value of an additional corresponding pixel in an additional image of the image sequence. After adding, the resulting TDI pixel value may be scaled based on the number of contributions.

Abstract: A system for scoring darts that includes multiple cameras placed substantially parallel to the surface of a dartboard. With a field of view extending across the board, the cameras can be configured to capture images of darts projecting outwardly from the board as they are thrown, and the system can use this image data to calculate the location of each dart, and the corresponding score. Various algorithms may be used to orient the system and calibrate the system to account for irregularities in the images captured by the cameras to accurately determine the location. Proper scoring may be achieved for a variety of dartboards with different patterns of scoring regions based on game rules and corresponding board configurations maintained by the system.

Abstract: A system and method whereby a group of synchronized anchor nodes transmit the identical radio signal packet at a specified time or specified times, which multiple signal packets are received at one or more tag/receiving nodes located within the area of use is provided. First, the time of each of the plurality of anchor nodes is synchronized relative to the other anchor nodes. A transmit time is then specified for each of the anchor nodes to transmit the identical data packet of information from each individual anchor node. The identical data packet of information and specified transmit time are then provided to each of the anchor nodes. The identical data packet of information is then transmitted from each anchor node into the area of use, wherein each of the identical data packets are transmitted from each respective one of the plurality of anchor nodes at the transmit time specified for that anchor node.

Abstract: System and method for scheduling and coordinating transmission signals in a wireless data communications network, comprising a master node and at least one tag node. In some embodiments, the network may also include a slave node. The master node divides time into repeating time division blocks comprising a configuration window and at least one transaction window. During the configuration window, the master node provides operating parameters to the tag or slave nodes, including a time slot within the transaction window that is reserved for the tag or slave nodes to broadcast data to the master node. The transaction window is subdivided into multiple reserved time slots, and each slot is assigned to a specific tag or slave node. When a reserved time slot arrives, the tag or slave node will broadcast data signals to the master node.
