Title: Method of removing semiconducting layers from a semiconducting substrate
Inventor: GANDROTHULA SRINIVAS
IPC: H01L29/78
Filed: 2019-05-30
Abstract: A method of removing semiconducting layers from a substrate, in particular, III-nitride-based semiconductor layers from a III-nitride-based substrate, with an attached film, using a peeling technique. The method comprises forming the semiconductor layers into island-like patterns on the substrate via an epitaxial lateral overgrowth method, with a horizontal trench extending inwards from the sides of the layers. Stress is induced in the layers by raising or lowering the temperature, and applying pressure to the attached film, such that the film firmly fits a shape of the layers. Differences in thermal expansion between the substrate and the film attached to the layers initiates a crack at an interface between the layers and the substrate, so that the layers can be removed from the substrate. Once the layers are removed, the substrate can be recycled, resulting in cost savings for device fabrication.

Title: User interface resource file optimization
Inventor: DIGNARD RYAN
IPC: G06F8/51
Filed: 2019-07-16
Abstract: Technologies described herein reduce the size of a software application. In some embodiments, the size of one or more resource files of an application are reduced. Resource files include key/value pairs that define elements of the application. In some embodiments, the application's source code is analyzed to determine if an entry in a resource file may be removed. For instance, initialization functions in the application's source code may be analyzed to determine if a value loaded from a resource file is replaced before being used. For example, a button with a color property may be defined as grey by a resource, but later set to orange in an initialization function. In this case, the resource entry defining button as grey is superfluous and may be safely removed. This technique allows for entries to be removed from a resource file even though the source code references the entries.

Title: System and method of pressure-controlled splitting of a chemical sample
Inventor: CARDIN DANIEL B
IPC: B01D15/18
Filed: 2019-10-24
Abstract: Pressure-controlled splitting can be used to inject a chemical sample from an injection source to a detector (e.g., a mass spectrometer) for chemical analysis (e.g., gas chromatography or gas chromatography-mass spectrometry) with reduced peak widths. For example, the sample is first transferred to a first compression volume; then pressure in the system is increased to compress the sample to split it between a second compression volume and a column. The fraction of the sample split to the column can have reduced peak widths compared to the peak widths prior to compression and splitting yet can maintain the same peak height to preserve high sensitivity for trace level analysis. This portion of the sample can traverse the column and elute to the detector for analysis with reduced chemical noise. Faster injection rates can allow faster analysis times, as less separation of chemicals is needed before the sample reaches the detector.

Inventor: OZCAN AYDOGAN
IPC: G06N20/00
Filed: 2019-11-14
Abstract: A trained deep neural network transforms an image of a sample obtained with a holographic microscope to an image that substantially resembles a microscopy image obtained with a microscope having a different microscopy image modality. Examples of different imaging modalities include bright-field, fluorescence, and dark-field. For bright-field applications, deep learning brings bright-field microscopy contrast to holographic images of a sample, bridging the volumetric imaging capability of holography with the speckle-free and artifact-free image contrast of bright-field microscopy. Holographic microscopy images obtained with a holographic microscope are input into a trained deep neural network to perform cross-modality image transformation from a digitally back-propagated hologram corresponding to a particular depth within a sample volume into an image that substantially resembles a microscopy image of the sample obtained at the same particular depth with a microscope having the different microscopy image modality.

Patent WO-2021118565-A1 (WO)
Inventor: SUN ZHIJIE
IPC: E21B47/00
Filed: 2019-12-12
Abstract: Certain aspects and features relate to a system that monitors for kick and lost circulation in the riser string of an offshore drilling rig. The system compensates for annulus outflow fluctuation induced by wave (heave) motion in order to reduce false alarms, resulting in fewer drilling operation disruptions. The system includes a sensor or sensors disposable with respect to a drilling rig subject to rig motion. A processor receives a real-time position signal indicative of the rig motion from the sensor and applies a state observer to the position signal to determine annular flow parameters. The system models an annular flow for the wellbore to produce a modeled flow signal that reflects a position of the drilling rig relative to influx flow. The system uses the modeled flow to determine kick-loss-alarm parameters that take into account the heave motion.
