  • Patent number: 9140751
    Abstract: An electronic package having multiple pins may be tested in parallel for output short circuit current by simulating a direct short to ground by simultaneously connecting multiple output pins directly to ground in order to active a current limiter associated with each of the output pins. The pins are then connected to a resistive connection to ground via a set of resistors; the direct ground is then removed, such that the current limiter associated with each of the output pins remains activated. A voltage drop across each of the set of resistors is measured simultaneously. An output short circuit current fault is indicated when the voltage drop across any of the resistors exceeds a threshold value corresponding to a maximum output short circuit current value.

  • Patent number: 5895791
    Abstract: In a method for obtaining near-surface characteristics of a material, a series of single frequency ultrasonic Rayleigh waves are generated, with a generating system, in the material. The Rayleigh waves are detected with a detection system remote from the generating system. Velocities of the detected Rayleigh waves are determined at the selected frequencies. A depth profile of one or more characteristics of the material is prepared based on the determined Rayleigh wave velocities.

  • Patent number: 5767408
    Abstract: In a method for obtaining near-surface characteristics of a material, a broadband ultrasonic Rayleigh wave including a plurality of components is generated, with a generating system, in the material. The Rayleigh wave is detected with a detection system remote from the generating station. The detected Rayleigh wave is filtered to obtain selected ones of the plurality of components of the detected Rayleigh wave at selected frequencies. Velocities of the selected components of the detected Rayleigh wave are determined at the selected frequencies. A system for obtaining near-surface characteristics of a material is also disclosed.
