Abstract: A method of laser distance measurement includes issuing a command from a single controller to a laser pulse emitter to emit a laser pulse. The method includes issuing a command from the single controller to a laser pulse detector to open for detection of a return of the laser pulse. The method includes detecting a return of the laser pulse, determining total time of travel for the laser pulse, and calculating a distance measurement based on the time of travel of the laser pulse.

Abstract: A computer system is provided that includes devices configured to acquire input data. The system further includes a remote node (RN) configured to receive a first packet from a control node (CN). The first packet includes a packet header including a master timestamp, first control data and a CRC. The RN is also configured to verify integrity of the first control data based on the received CRC, generate and transmit to the CN a second packet. The second packet includes a packet header which includes a remote timestamp. The system also includes a CN connected with the RN via high-speed serial interfaces. The CN is configured to receive the second packet, determine status of the first packet based on the control data included in the second packet and configured to retransmit the first packet or generate and transmit a third packet based on the determined status of the first packet.

Abstract: A computer system is provided for exchanging data with a second computer system using a one-way protocol. The computer system includes a communication port, a memory configured to store instructions, and a processor disposed in communication with the memory. The processor upon execution of the instructions is configured to receive via the communication port a plurality of data packets of a data transmission transmitted in accordance with a one-way protocol from the second computer system, the data transmission representing a data structure, each data packet having a header that indicates a data type of the data transmission, and determine if a data packet of the data transmission is missing based on the data type and the number of data packets received.

Abstract: A method for applying probability functions in real time includes receiving an input value. An optimized binary sequence is selected from a lookup table based on the received input value. The lookup table includes probability values of at least a part of a noise probability sequence. The input value is masked by a least significant bit of the selected optimized binary sequence to yield an output value. The selected optimized binary sequence is right shifted by one bit and the right shifted bit is carried over to a most significant bit position of the selected optimized binary sequence.
