Abstract: A method and system for authenticating and enabling activation of a configuration used for controlling a product, where the configuration is implemented as safety critical logic functions in programmable logic blocks of a Field Programmable Gate Array, FPGA, having a volatile configuration-memory. The configuration is loaded into the volatile configuration-memory of the FPGA via an external interface input of the FPGA. The content of the configuration-memory of the FPGA is read via an interface of the FPGA. This is done immediately after completed loading of the configuration into the memory of the FPGA. A Cyclic Redundancy Check, CRC, checksum of the read content of the configuration-memory is computed in an CRC checksum generator, and a resulting generated CRC checksum value is compared with an externally stored valid CRC checksum value of the expected FPGA configuration.

Abstract: A method and apparatus for detecting and classifying submerged swimming object from a passive signal generated by, and an active signal reflected from the object. In a first input of a passive mode branch a first signal representative of the passive signal is received. A second signal representative of the active signal is received in a second input of an active mode branch. In the active mode branch, the first signal is processed to generate a first classification estimate output, with first clues, of the most probable class of target for the object. In the passive mode branch, the second signal is processed to generate a second classification estimate output, with first clues, of the most probable class of target for the object. Both estimate outputs are received in a merger, for generating a merged classification estimate output with clues, which is input to a joint classifier that classifies the object.
