Abstract: The present invention provides techniques for detecting foreign objects in a region of interest in maritime environments. Image data indicative of a sequence of successively acquired images of the region of interest, is analyzed to determine candidate points of interest, and data indicative of said points is processed to identify candidate points that are adjacently accumulated in different locations in images data. Grouping data may be then generated based on the identified accumulations of candidate points indicative of a group of said candidate points. The grouping data is processed to identify spatio-temporal correlation between the points in the group and determine a corresponding track function, thereby enabling detection of a presence of a foreign object in the image data.

Abstract: An engine control unit with distributed processing includes a main ECU and remote modules with sensor inputs and ignition and injector outputs. A bidirectional asynchronous CAN data bus and a square wave timing signal operatively connect the components. Synchronous ignition and ignition data and asynchronous sensor and control data are concurrently transmitted between components using CAN messaging. Synchronicity is accomplished using the timing signal. The rising edge of each pulse triggers dwell and injection start times, and the falling edge triggers ignition. Injection and dwell time values, the cylinders to dwell and fire, and the injectors to energize, are transmitted using CAN messaging. The remote modules process the control messages and timing signal and generate the appropriate ignition, injector, and pulse width modulation control signals. Alternatively, time stamp capabilities of the CAN bus topology are used for synchronization.
