Abstract: A method provides a tamper loop status of a radio-frequency transponder to a reader. The transponder communicates with the reader at a first frequency according to a first communication protocol. The transponder includes a first non-volatile memory for storing a first set of data of the first communication protocol. The first memory includes a user memory having two portions and each portion includes a data item specific to a status of the tamper loop. The method is performed by the transponder after receiving a request according to the first protocol to read the user memory and includes generating a logical view of the user memory, the logical view including only one of the two portions that is selected according to a value of a binary parameter representative of a status of the tamper loop. The method also includes providing the logical view to the reader via the first protocol.

Abstract: Techniques are disclosed for systems and methods for providing accurate and reliable compact sonar systems for mobile structures. In one embodiment, a sonar system includes a mounting bracket, a transducer support arm, and a pivoting mechanism pivotably coupling the transducer support arm to the mounting bracket such that, for forces acting on the transducer support arm that are less than a preselected kick-up level, the pivoting mechanism holds the transducer support arm against such forces and at a user selectable first angular position relative to the mounting bracket, and for forces acting on the transducer support arm that are equal to or greater than the preselected kick-up level, allows the transducer support arm to be moved by those forces to a second angular position relative to the mounting bracket.

Abstract: Techniques are disclosed for systems and methods to provide accurate and reliable compact sonar systems for mobile structures. A sonar system includes multiple sensor channels, each comprising a sonar transmitter and a sonar receiver, and a logic device configured to provide control signals and receive sensor signals from the sensor channels. The logic device is configured to provide transmission signals to sonar transducer assemblies, where signal patterns of the transmission signals are differentiated based at least in part on frequency content. Acoustic returns are processed using the signal patterns to reduce inter-channel pickup between the sensor channels. Resulting sonar data and/or imagery may be displayed to a user and/or used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

Abstract: A multiple processor core computer system interface assigns instructions to partially functional processor cores based on processing resources available in each partially functional core. Each processor core is labeled as fully functional, partially functional, or non-functional, and an indicator is provided for each partially functional processor core that shows what processing resources are available for a respective core. The indicators can be stored in memory after final test. The interface can monitor cores for changes in available resources and update respective indicators, such as by superseding an existing indicator with or creating a new indicator in read-write memory.

Abstract: A mechanism is provided for validating overall resilience and security characteristics of a sub-component chip design. For each instance of a resiliency template identified as appearing in a design netlist of the sub-component chip design thereby forming one or more identified resiliency sections, a determination is made as to whether an output of the design netlist where an error signal is output interconnects to the one or more identified resiliency sections of the design netlist. Responsive to the one or more identified resiliency sections interconnecting to the output of the design netlist where the error signal is output, one or more identified resiliency sections are marked as being protected by the error signal. An identification of the one or more identified resiliency sections and an identification of the error signal protecting the one or more identified resiliency sections are output to a design team.
