Patent number: 11251601Abstract: Techniques are provided for non-volatile detection of an overvoltage condition in a circuit of interest. A circuit implementing the techniques according to an embodiment includes a fuse configured to provide a non-volatile indication of an overvoltage event, the indication associated with an open state of the fuse. The circuit also includes a voltage controlled current switch coupled in series to the fuse. The voltage controlled current switch is configured to enable current flow through the fuse in response to a supply voltage exceeding a threshold value associated with the overvoltage event. The current causes the fuse to switch from a closed state to an open state providing a non-volatile record of the overvoltage event. In some embodiments, the voltage controlled current switch can be a Zener diode with a breakdown voltage based on the threshold value, or a transistor configured to switch into conducting mode at the threshold value.Type: GrantFiled: April 14, 2020Date of Patent: February 15, 2022Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Richard J.

Publication number: 20220043639Abstract: The system and method for decoupling algorithms from a Mission Data Tool suite, or the like, into a scalable, modular and multithreaded tool set callable from a variety of environments. The system generates data objects representing inputs, outputs and field validation capable of being accessed from a framework callable from Java or C#, for example. Data objects are defined in an abstract Independent Definition Language (IDL) and the objects are then generated into the target languages for use by a software component's application programming interface (API). The resulting generated code may also contain serialization/deserialization routines needed for object transfer between different systems in a seamless manner. In some cases, transfer of the objects, algorithmic generation of data into the objects, and the transfer of outputs back to the calling system is possible with minimal overhead and interaction on either end.Type: ApplicationFiled: June 21, 2019Publication date: February 10, 2022Applicant: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Mark R.

Patent number: 11223365Abstract: A system and method for suppressing aperture noise resulting from clock jitter associated with a Nyquist analog-to-digital converter (ADC) using self-referred time measurements are provided. The system comprises of a clock, a delay element, a time subtractor, a time-to-digital converter, a filter element, a first digital subtractor, an integrator, a differentiator, and a multiplier. Each of the delay element, time subtractor, time-to-digital converter, filter element, first digital subtractor, integrator, and multiplier is electrically connected in parallel with the ADC, which allows the clock to generate a clock signal that advances into the system and the ADC in order to isolate and suppress the noise aperture associated with the ADC.

Patent number: 11218513Abstract: Techniques are disclosed for providing information sharing with enhanced security. In an embodiment, a secure information sharing engine provides secure sharing of data by applying one or more validation rules to the data. When applied to a given portion of the data, the validation rule verifies that the data of the given portion is, in fact, the data that is supposed to be in the given portion. At least one of the validation rules includes a check that a portion of the data contained in multiple fields maintain a relationship between the multiple fields. If the data passes the applied one or more validation rules, the secure information sharing engine allows the sharing of the data. Otherwise, if the data does not pass the one or more applied validation rules, the secure information sharing engine disallows the sharing of the data.Type: GrantFiled: May 22, 2019Date of Patent: January 4, 2022Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Kenneth A.

Patent number: 11215454Abstract: A system for finding up in a projectile flight relative to earth. The system having a transmitter which transmits polarized reference signals to a guidance sub-system on the projectile. The guidance sub-system includes a magnetometer and polarized and non-polarized receivers. Measurements from the magnetometer are used to determine a general up direction. The polarized and non-polarized receivers are arranged such that, during rotation of the projectile, reference signals received by the polarized receiver modulate whereas reference signals received by the non-polarized receivers are unaffected. A ratio of the strengths of the signals received by the polarized and non-polarized receivers determines alignment of a vertical axis. From the general up direction and alignment of the vertical axis, a precise up direction of the projectile in flight relative to the earth can be determined.Type: GrantFiled: April 4, 2019Date of Patent: January 4, 2022Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Michael J.
