Abstract: A method includes forming a flip-chip module including a chip connected to a substrate with a layer of underfill material adhered to the chip and the substrate; sensing chip-packaging interaction failure in the underfilled flip-chip module in situ; reporting in-situ chip-packaging interaction failure to a device in real-time; and imaging the chip-packaging interaction failure with an indirect scanning acoustic microscope.

Abstract: A laminate includes a plurality of buildup layers disposed on a core and a plurality of unit cells defined in the buildup layers. Each unit cell includes: at least one test via that passes through at least two of the buildup layers and that is electrically connected to testing locations on a probe accessible location of the laminate; and two or more dummy vias disposed in the unit cell. The dummy vias are arranged in the unit cell at one of a plurality of distances from the test via.

Abstract: Flip-chip package reliability monitoring and systems of monitoring using capacitive sensors are disclosed. The monitoring is conducted in situ and in real-time without the need for destructive testing of the packages. The capacitive sensors can be used for flip-chip package reliability monitoring.

Abstract: A method and system for acquiring data for assessment of cardiovascular disease, the method comprising one or more of: manipulating one or more hardware aspects of the photoplethysmography data acquisition system(s) implementing the method; manipulating or providing user experience/user interface (UX/UI) aspects of the system(s) implementing the method; acquiring, processing, and deriving insights population specific data; accounting for or controlling sampling site variability; and using other suitable sources of data in order to generate high quality data for characterization, assessment, and management of cardiovascular disease.

Abstract: An embodiment of a method for assessing cardiovascular disease in a user with a body region using a mobile computing device including a camera module, includes receiving a time series of image data of a body region of the user, the time series of image data captured during a time period; generating a photoplethysmogram dataset from the time series of image data; generating a processed PPG dataset; determining a cardiovascular parameter value of the user based on the processed PPG dataset; fitting a chronobiological model to (1) the cardiovascular parameter value, and (2) a subsequent cardiovascular parameter value, characterizing a cardiovascular parameter variation over time of the user based on the fitted chronobiological model; and presenting an analysis of the cardiovascular parameter variation to the user at the mobile computing device.

Abstract: A lidded or lidless flip-chip package includes two or more polygon shaped dies. The polygon dies may be interconnected to a substrate or to an interposer interconnected to a substrate. The interposer may be similarly shaped with respect to the polygon die(s). For the lidless or lidded package, the package may include underfill under the polygon dies surrounding associated interconnects. For the lidded package, the package may also include thermal interface materials, seal bands, and a lid. The polygon die package reduces shear stress between the polygon die/interposer and associated underfill as compared to square or rectangular shaped die/interposer of the same area. The polygon dies further maximize the utilization of a wafer from upon which the polygon dies are fabricated. The multi polygon die package may allow for a significant reduction of the polygon die to polygon die relative to the spacing and may reduce signal interconnect time.

Abstract: A method of securely storing and sharing information through social networking websites is disclosed. The method makes it possible to proscribe image data that retains information even through the JPEG compression process typically used in social networking sites. This embedding technique is coupled with encryption and information salting techniques to build a robust information encoding technique to store arbitrary, sensitive data in images. The invention further incorporates methods of permitting advertising through the information sharing process.

Abstract: A cortical surface registration procedure related to a diagnostic or surgical procedure. In one embodiment, the procedure includes the steps of pre-operatively obtaining a first textured point cloud of the cortical surface of a targeted region of a brain of a living subject, intra-operatively obtaining optically a second textured point cloud of the cortical surface of the brain of the living subject, and aligning the first textured point cloud of the cortical surface to the second textured point cloud of the cortical surface so as to register images of the brain of the living subject to the cortical surface of the living subject.
