Patents awarded

(Oldenzaal, the Netherlands, April 12, 2017)DapTechnology B.V. today announced that two if its patent applications regarding IEEE-1394 technology have been awarded by the US Patent and Trademark Office (USPTO).

U.S. Patent 9,575,866 on "Diagnostic Module for Monitoring Electric Data Transmission" (issued on Feb.21, 2017) describes a Sub-Diagnostic Module incorporated into a System Module. The Sub-Diagnostic Module receives signals from the System Modules through the diagnostic signal interface. The diagnostic signal interface passes the signals through to the diagnostic signal evaluation logic where it determines if a signal or combination of signals is an event to be recorded in the sub-diagnostic registers and/or the sub-diagnostic log memory. The events recorded in the registers and log memory are accessed by the Portable Diagnostic Module through the Sub-Diagnostic Module's diagnostic protocol interface. Recorded events placed in log memory are synchronized by the sub-diagnostic time synchronizer. The time synchronizer receives high resolution time information from a local clock, such as a physical layer clock, and lower resolution network synchronized information from the diagnostic protocol interface.

U.S. Patent 9,602,302 on "Method for disabling a Legacy Loop Detect Circuit in a Beta Node" (issued on Feb.27, 2017) describes a method for disabling or removing a Legacy loop detect circuit to eliminate the circuit erroneously detecting a legacy loop during a IEEE-1394 serial bus initialization. The method includes providing a programmable code to the Legacy loop detect circuit for increasing a reset count to a value greater than three (3) to the Legacy loop circuit thus reducing the probability of an erroneous disconnect of a Beta node connection. This method provides for more robust Beta loop node operation during high frequency bus resets.

Both patent awards affirm the company's leading position in IEEE-1394 and AS5643 technology and its continued quest to develop leading edge solution. Furthermore, the awards honor two essential components in the company's growing pool of technology components. DapTechnology spends considerable efforts in improving key technology elements for AS5643 and IEEE-1394 in order to improve network stability and reliability in deterministic avionics control systems. The now patented technologies are or will be incorporated in several products from DapTechnology.
