Title: Matching rgb images to cad models
Inventor: GEORGAKIS GEORGIOS
IPC: G06K9/00
Filed: 2019-07-09
Abstract: A training method for networks includes rendering depth images of an object, creating a triplet comprising a picture of the object, a first one depth image that is view-invariant with the picture and modality-invariant with second depth image and scanning each sector of the picture and the first and second of the depth images. The training method further includes configuring the network to iteratively derive feature descriptions for each of the sectors from the scanning, propose certain sectors as keypoint-sectors based on the feature descriptions, generate local-alignment and relative-pose scores for each proposed keypoint-sector of the first and second ones of the depth images and consistency scores for each proposed keypoint-sector of the picture and the first one of the depth images; and refine the feature descriptions and proposals based thereon toward improving the local-alignment, the relative-pose and the consistency scores.

Title: Laser lift-off masks
Inventor: BRODOCEANU DANIEL
IPC: H01L33/00
Filed: 2019-07-30
Abstract: Techniques related to laser lift-off masks are disclosed. In some embodiments, masking material is applied to a substrate that is attached to a plurality of semi conductor device sets. More specifically, the masking material is applied to one or more regions of the substrate between the semiconductor device sets. When the semiconductor device sets are embedded in a filling material, the masking material may be situated between the substrate and the filling material. Thus, transmitting light through the substrate toward the semiconductor device sets causes the substrate to become detached from the semiconductor device sets. However, the light is at least partially occluded by the masking material.

Title: Pupil modulation as a cognitive control signal
Inventor: BAR-ZEEV AVI
IPC: G06K9/00
Filed: 2019-09-13
Abstract: One exemplary implementation provides an improved user experience on a device by using physiological data to initiate a user interaction for the user experience based on an identified interest or intention of a user. For example, a sensor may obtain physiological data (e.g., pupil diameter) of a user during a user experience in which content is displayed on a display. The physiological data varies over time during the user experience and a pattern is detected. The detected pattern is used to identify an interest of the user in the content or an intention of the user regarding the content. The user interaction is then initiated based on the identified interest or the identified intention.

Patent WO-2020076713-A1 (WO)
Inventor: KACZYNSKI BRIAN
IPC: G01R23/02
Filed: 2019-10-07
Abstract: Methods and digital circuits provide frequency correction to frequency synthesizers. Dual switched-capacitor voltage detectors connected to an input signal periodically sample the voltage of the input signal, and then determine a fundamental frequency of the input signal from the output of the dual switched-capacitor voltage detectors. The sample period of the dual switched-capacitor voltage detectors is proportional to a time period between a previous pair of voltage peaks detected in the input signal, thereby eliminating harmonic components in the original signal which might otherwise cause errors in frequency estimation without causing unwanted sluggishness in the transient response of the frequency detection process. The time period between the previous pair of detected voltage peaks is used to create a decay signal that initiates a capacitor decay time for each voltage detector. Two additional digital methods of extracting the fundamental frequency as well as an envelope of an analog audio signal are also described, one utilizing a sliding sample rate, and the other utilizing a fixed sample rate.

Filed: 2019-10-29
Abstract: A method and system for automatically generating a video stream synchronized with and reactive to an input audio stream uses one or more still or video images as a source of imagery. The system learns a latent representation of the source imagery and generates a visualization synchronized to, and reactive with, the input audio. A computer divides the audio stream into successive audio frames each characterized by a spectrogram. The computer generates a series of graphics of such latent representation according to the spectrogram of each audio frame. The computer pairs each audio frame with its corresponding graphic to generate an ordered series of graphics. The series of generated graphics can be displayed to accompany the audio in real-time or coupled with the audio stream to provide an audiovisual work that can be transmitted or digitally stored.
