  • Patent number: 8650512
    Abstract: Computer-implemented methods are disclosed for providing an elastic modulus map of an integrated circuit (IC) chip of a chip/device package, for identifying a probable failure site of the chip/device package from the elastic modulus map of the IC chip, for modifying a connector footprint of the chip/device package based on identifying a probable failure site from the elastic modulus map of the IC chip, and for modifying the IC chip based on identifying a probable failure from the elastic modulus map of the IC chip. Each layer of the IC chip may be mapped, and each grid shape of the mapped layers may comprise a metal area and a dielectric area. Grid shapes from each layer of the IC are vertically aligned to provide a combined spring constant for each grid shape, which are then mapped onto the elastic modulus map to identify possible failure sites in the chip/device package.

  • Patent number: 8634677
    Abstract: Some embodiments provide a method and system for efficiently transferring medical images. Some embodiments receive a medical image in a first platform dependent format of a Picture Archiving and Communication System (PACS). The first platform dependent format is one that is accessible by a first format compliant device that includes a library that specifies how to decode the first format. Some embodiments transform the medical image from the first format to a second format. The second format includes decoded content of the first format that is viewable on a first format non-compliant device. The transformed image is then passed to the device for viewing. Additionally, some embodiments efficiently transfer medical images by identifying image settings for one or more devices and by passing requested images that are optimized by resizing the images according to the image settings of the requesting device.

  • Publication number: 20130052798
    Abstract: A spalling method is provided that includes depositing a stressor layer on surface of a base substrate, and contacting the stressor layer with a planar transfer. The planar transfer surface is then traversed along a plane that is parallel to and having a vertical offset from the upper surface of the base substrate. The planar transfer surface is traversed in a direction from a first edge of the base substrate to an opposing second edge of the base substrate to cleave the base substrate and transfer a spalled portion of the base substrate to the planar transfer surface. The vertical offset between the plane along which the planar transfer surface is traversed and the upper surface of the base substrate is a fixed distance. The fixed distance of the vertical offset provides a uniform spalling force. A spalling method is also provided that includes a transfer roller.

  • Patent number: 8352216
    Abstract: A method for advanced condition monitoring of an asset system includes sensing actual values of an operating condition for an operating regime of the asset system using at least one sensor; estimating sensed values of the operating condition by using an auto-associative neural network; determining a residual vector between the estimated sensed values and the actual values; and performing a fault diagnostic on the residual vector. In another method, an operating space of the asset system is segmented into operating regimes; the auto-associative neural network determines estimates of actual measured values; a residual vector is determined from the auto-associative neural network; a fault diagnostic is performed on the residual vector; and a change of the operation of the asset system is determined by analysis of the residual vector. An alert is provided if necessary. A smart sensor system includes an on-board processing unit for performing the method of the invention.
