  • Patent number: 10782336
    Abstract: Embodiments are directed to a system for measuring a degradation characteristic of a plurality of electronic components. The system includes a parallel stress generator communicatively coupled to the plurality of electronic components, and a serial electronic measuring component communicatively coupled to the plurality of electronic components. The parallel stress generator is configured to generate a plurality of stress signals, apply the plurality of stress signals in parallel to the plurality of electronic components and remove the plurality of stress signals from the plurality of electronic components. The serial electronic measuring component is configured to, subsequent to the removal of the plurality of stress signals, sequentially measure the degradation characteristic of each one of the plurality of electronic components in order to determine their degradation resulting from the applied stress signals.

  • Patent number: 10746785
    Abstract: A method and circuit of monitoring an effective age of a target circuit are provided. A standby mode is activated in the target circuit. A standby current of a first number of circuit blocks of the target circuit is measured. The measured standby current of the first number of circuit blocks is compared to a first baseline standby current of the first number of circuit blocks. Upon determining that the measured standby current of the first number of circuit blocks is below a first predetermined factor of a baseline standby current of the first number of circuit blocks, the first number of circuit blocks is identified to have a bias temperature instability (BTI) degradation concern.

  • Patent number: 10671958
    Abstract: A computer-implemented method for analyzing customer satisfaction is presented. The computer-implemented method may include capturing visual images related to individuals and order consumables, determining, by a processor, at least one measurable metric to predict variations indicating different satisfaction levels, and dynamically refining parameters if the variations exceed one or more thresholds. The computer-implemented method further includes receiving the captured visual images of the individuals and the order consumables by least one camera in communication with the processor.

  • Publication number: 20200150181
    Abstract: Methods and systems of detecting chip degradation are described. A processor may execute a test on a device at a first time, where the test includes executable instructions for the device to execute a task under specific conditions relating to a performance attribute. The processor may receive performance data indicating a set of outcomes from the task executed by the device during the test. The processor may determine a first value of a parameter of the performance attribute based on the identified subset. The processor may compare the first value with a second value of the parameter of the performance attribute. The second value is based on an execution of the test on the device at a second time. The processor may determine a degradation status of the device based on the comparison of the first value with the second value.

  • Patent number: 10552278
    Abstract: A method and system are provided for chip testing. The method includes selectively deploying a chip for future use or discarding the chip to prevent the future use, responsive to a stress history of the chip determined using a non-destructive test procedure. The test procedure includes ordering each of a plurality of functional patterns by a respective minimum operating period corresponding thereto. The test procedure further includes ranking each of the plurality of patterns based on at least one preceding available pattern to provide a plurality of pattern ranks. The test procedure also includes calculating a sum by summing the plurality of pattern ranks. The sum calculated during an initial performance of the test procedure is designated as a baseline, and the sum calculated during a subsequent performance of the test procedure is compared to a threshold derived from the baseline to determine the stress history of the chip.

  • Patent number: 10433173
    Abstract: A method for gaining access beyond a restricted access gateway includes an access key sequence stored on memory of a device. The access key sequence includes a sequence of key entries and key touch movements. An entered request sequence including keys activated by touch on a keyboard of the device and directions of touch movements made on the keyboard is recorded. With an access controller, it is determined whether the recorded entered request sequence matches the access key sequence. Access beyond the restricted access gateway is granted to functions when the recorded entered request sequence matches the access key sequence.

  • Patent number: 10388580
    Abstract: Methods and circuits for monitoring circuit degradation include measuring degradation in a set of on-chip test oscillators that vary according to a quantity that influences a first type of degradation. A second type of contribution to the measured degradation is determined by extrapolating from the measured degradation for the plurality of test oscillators. The second type of contribution is subtracted from the measured degradation at a predetermined value of the quantity to determine the first type of degradation for devices represented by the predetermined value.

  • Patent number: 10365702
    Abstract: Over at least part of a lifetime of a product circuit, quiescent current to a product circuit is periodically measured. Over the part of the lifetime of the product circuit, voltage to the product circuit is periodically adjusted based on the monitored quiescent current. Methods, apparatus, and computer program product are disclosed. A calibration procedure may also be performed as part of manufacturing the product circuit, in order to provide values for the quiescent current and corresponding voltage to which the voltage should be adjusted.

  • Patent number: 6057847
    Abstract: A computer-implemented method of image generation that makes efficient use of reprojective techniques to reduce the cost of image generation. The method employs a technique of primitive reprojection in which convex graphics primitives are the reprojected elements. The visibility of elements known to be visible in a previous frame is first determined by transformation and depth-comparison rasterization of these elements. Regions of the image that may contain newly visible elements are located by occlusion-exposure transitions in the depth buffer and from incremental view volume motion. In these regions a depth-prioritized, data-access method of visible surface determination, spatial-subdivision ray casting, is employed to identify newly visible primitives which are added to the list of previously visible primitives for rasterization. The method employs a system of classifying objects based on their dynamic occlusive properties to increase the accuracy, efficiency and versatility of the reprojective approach.

  • Patent number: 6028608
    Abstract: A computer implemented method of image generation that employs adaptive, progressive, perception-based spatio-temporal importance sampling to reduce the cost of image generation. The method uses an adaptive approach to sampling which employs refinement criteria based on specific spatio-temporal limits of human vision. By using these refinement criteria the method produces an image with a spatio-temporal structure that is closely matched to the spatio-temporal limits of human vision. Using one sampling criteria the spatial sampling density is adjusted in proportion to the sampled region's exposure duration in a manner that substantially reflects the visual systems's increase in acuity as a function of exposure time.
