    摘要: A method for initializing a chain of non-initialized data collectors is disclosed. The chain of non-initialized data collectors are coupled to a controller. In a first step communication between the controller and each data collector in the chain of non-initialized collectors is disabled, except for an active non-initialized data collector, The active non-initialized collector is coupled to the controller and any remaining non-initialized data collectors. Next, the active non-initialized data collector is initialized by assigning an identification number to the active non-initialized data collectors. The active non-initialized collector becomes an initialized data collector. Then, communication is restored between the initialized data collector and a next active non-initialized data collector in the chain of non-initialized data collectors. The method repeats until all non-initialized data collectors are initialized.

    摘要: An improved band seal clamp for clamping of tubular members is disclosed which features a band-like clamping member having slots formed in its ends for interaction with bolts held rigidly in holes formed in a spacing member disposed between the ends of the clamp. The ends of the band are shaped to define surfaces at an angle with respect to the surface of the tubular members which coact with force bars having corresponding shapes. Throughbolts fit through the slots in the band, holes in the force bars and the holes in the spacing member, so that upon tightening of the bolts the ends of the band clamp are forced outward, thus exerting a compressive stress on the tubular member.

    摘要: In the present invention, a method is provided for installing and locating a plurality of sensors distributed on a structure as part of a structural health monitoring system. The method includes verifying the proper installation of the plurality of sensors and determining the location of the plurality of sensors. In one aspect of the present invention, the step of verifying the proper installation further comprises verifying that each of the plurality of sensors are properly coupled to a sensor data collector and verifying that each of the plurality of sensors are installed in a proper location. In another aspect of the present invention, the step of determining the location of the plurality of sensors further comprises determining the positioning of each sensor in reference to fixed structures in the structure.

    摘要: A highly reliable data processing system using the pair-spare architecture obviates the need for separate memory arrays for each processor. A single memory is shared between each pair of processors wherein a linear block code error detection scheme is implemented with each shared memory, wherein the effect of random memory faults is sufficiently detected such that the inherent fault tolerance of a pair-spare architecture is not compromised.

    摘要: A method for operating a memory checker in a command monitoring architecture comprising at least two processing lanes comprises a first step of receiving a command to activate a first test mode. The first test mode comprises an initial step of inverting data read from a memory and inverting data written to the memory. Next, it is determined if there is a match between data associated with a first processing lane and retrieved by a second checker logic associated with a second processing lane and with data associated with a second processing lane and retrieved by a first checker logic associated with the first processing lane. A failure in the memory is determined if there is no match.
