Abstract: A method to detect, identify and determine the position of laser points from infrared laser emitters in a firearm training simulation system. The method consists of two steps. This first step combines some common tools such as a camera with a filter switcher and edge and corner detecting algorithms in image processing to provide a fast automatic screen calibrating method. The second step is to detect laser point objects in each frame continuously captured by the camera, and then further process these objects to identify laser shots, filter out noisy objects, and eventually detect simulated shots from different laser emitters and determine the final mapped position of the shot.

Abstract: Managing prefix lists at edge devices can include detecting, at an edge device, a traffic flow that can include a packet that specifies a destination address. The edge device can measure a bandwidth associated with the traffic flow, identify a flow bandwidth threshold defined for the edge device, and determine if the bandwidth associated with the traffic flow satisfies the flow bandwidth threshold. If a determination is made that the bandwidth associated with the traffic flow satisfies the flow bandwidth threshold, the edge device can include the destination address in a prefix list stored at the edge device. If a determination is made that the bandwidth associated with the traffic flow does not satisfy the flow bandwidth threshold, the edge device can omit the destination address from the prefix list stored at the edge device.

Abstract: A processing system may obtain a first sampled flow record for a first flow in a network, comprising information regarding selected packets of the first flow, derive, from the first sampled flow record, a data volume and a duration of the first flow, and determine a first flow metric for the first flow that is calculated from the data volume and the duration, where the first flow metric is one of a plurality of flow metrics for a plurality of flows, and where the plurality of flow metrics is determined from the plurality of sampled flow records associated with the plurality of flows. The processing system may then classify the first flow into one of at least two classes, based upon the first flow metric and at least a first flow metric threshold.

Abstract: A circuit breaker includes a monitor to detect a performance of an electrical load in an electrical circuit, a converter to create a digital signal based on the detected performance of the electrical load, and a digital integrated circuit to compare the digital signal with a predetermined threshold reference signal, and generate a command signal to electrically disconnect the electrical load from the electrical circuit when a level of the digital signal exceeds the predetermined threshold reference signal. The electrical load may be configured to receive a fixed or variable amount of current or voltage. The predetermined threshold reference signal may include a signal level threshold and a time threshold. The digital integrated circuit may generate the command signal when the level of the digital signal exceeds the signal level threshold and the detected performance of the electrical load exceeds the time threshold.

An input port of a network device is tapped to duplicate an input packet stream having a first packet. An output port of the network device is tapped to duplicate an output packet stream including the first packet.

The difference between the departure time of the first packet and the arrival time of the first packet is determined and the value is reported to an external collector.
