Title: Jog detector
Inventor: DOUCET KEITH R
IPC: H04K3/00
Filed: 1991-10-28
Abstract: ABSTRACT         A shipborne Electric Countermeasures (ECM) system protects ships against an approaching missile by transmitting electromagnetic jamming signals directly at the missile's radar in order to disturb its range and angle tracking system sufficiently to prevent the missile from intercepting the ship.  Various jamming techniques are transmitted until one is found that causes an angle deflection or "jog" in the radar transmitting antenna of the missile.  The ECM's receiver looks for a sudden drop in the strength of the radar signal transmitted by the missile's radar, which indicates that a "jog" may have occurred, in order to determine if a jamming technique is effective.  Multipath disturbances due to forward scattering interference also cause drops in the strength of a received radar signal but these types of signal fluctuations are a height dependent phenomenon.  This ECM system differentiates between multipath disturbances and actual "jogs" by using a receiving antenna array with a number of antennas located at different heights.  The vertically separated antenna measures drops in signal strength at different times if these drops are caused by multipath disturbances.  However, any drops in signal strength caused by a "jog" reach all the antennas at the same time and are measured simultaneously providing an indication that a "jog" has occurred.

Abstract: A central processing unit arrangement for detecting a fault in a central processing unit system that includes a master processor and a slave processor.      Master and slave processors are resynchronized at every bus cycle by conditioning the processors' READY signal with the ADS (address status) signals from each processor (ADS indicates that an access cycle has begun and a valid address is present on the address bus). This method of synchronization was selected over the more traditional method of lock-step, which was deemed impractical to implement given the timing constraints of a high speed bus. Also, the dual processors may not always begin their respective bus cycles on the same clock. In addition, it is necessary to synchronize processors for the first instruction fetch following a reset, because the time of completion of an internal self-test may not be deterministic. After both ADS signals are received, the status of the master and slave buses are compared and a fault is detected if the buses are different. If a predetermined amount of time passes before both ADS signals are received then the processors are signaled to continue with the cycle.      Because the processors are no longer synchronized, the buses will miscompare, thereby detecting a fault.       Additional fault detection measures can be taken such as parity, checksum and EDAC.

Abstract: A system for monitoring an ATM cross-connecting apparatus by rewriting a VPI conversion table to various values, inputting a test cell, and examining the test cell after the test cell passes through the ATM cross-connecting apparatus. Entries of a VPI conversion table are accompanied by traffic flags indicating whether or not the corresponding entry is occupied for use for user's signals. First, the traffic flags are examined. Each entry not occupied for user's signals can be freely rewritten. Each entry  occupied for user's signals is not rewritten. The examination of the test cell is carried out by comparing the test cell output from the ATM cross-connecting apparatus, with a reference cell which is expected from a normal operation of the ATM cross-connecting apparatus. The virtual path identifier converted in the ATM cross-connecting apparatus and contained in the output test cell, is expected corresponding to the above rewriting operations, and is contained in the reference cell.

Abstract: FLEXIBLE INTERFACE SYSTEM FOR INTERFACING DIFFERENT      COMPLEMENTS OF PORT CIRCUITS TO A PCM TELEPHONY             SWITCHING SYSTEM     Abstract An interface system for port circuits of a distributed PCM telephony switching system enables different complements of port circuits (different numbers of line circuits or of trunk circuits or of digital circuits which handle multiple party conferences) to be connected into the PCM telephony switching system so as to meet different user requirements.  The interface system handles the PCM data signals carrying voice (analog) and digital information. The interface system also handles control signals generated in the telephony processor and transfers the data between the port circuits and the highways of the PCM switching system in sequential time slots.  The timing of the time slots, the allocation of the time slots to different data is selectable by manually, configurable, programmable, switching devices which set up codes and connections corresponding to the complement of port circuits which are to be interfaced with the PCM telephony switching system.  These switching devices are implemented by programmable headers having conductive elements which may be left intact or severed. The same interface circuitry, but with different connections intact and severed in their programmable headers, is used to establish the timing and allocate time slots in accordance with the configuration of port circuits selected by the user of the telephony system, thereby opening the architecture of the telephony system to different port circuit arrangements while isolating the telephony system from the port circuits for safety and security of operation of the telephony system.
