Abstract: A system and method for object detection and classification includes receiving by a controller a first data of a scene, wherein the data reflects the scene at a first time, and performing a first classification of at least one object within the scene based on the data. The method includes determining a projected location of the at least one object corresponding to an estimated location at a second time. The method includes receiving a second data of the scene reflecting the scene at the second time. The method includes determining whether the projected location of the object corresponds to the location of the object as reflected by the second data. The method includes determining whether performing a second classification of the object is necessary based on the determination of whether the projected location corresponds to the location of the object reflected by the second data.

Abstract: A system and method for transmitting a plurality of signals. The system includes a transmitting terminal configured to obtain and pack the plurality of signals in multiple signal sequences, with each of the plurality of signals having respective predefined periods. A receiving terminal is configured to receive and unpack the multiple signal sequences from the transmitting terminal. A controller is in communication with the transmitting terminal and the receiving terminal and configured to store a look-up table. The look-up table includes a respective pre-identifier and respective identifier for each of the plurality of signals. The controller is configured to determine if the respective predefined periods vary in magnitude within a frame. If so, the controller is configured to obtain the respective pre-identifiers and respective identifiers for each of the plurality of signals. The multiple signal sequences are based at least partially on the respective pre-identifiers and the respective identifiers.
