Abstract: A method for analyzing environmental sounds to identify repeating noises due to power equipment for purposes of controlling noise pollution is disclosed. Ambient sounds are sampled with microphones and the resulting data analyzed by an edge computing device. The samples are compared to stored data with a convolutional neural network by the edge computing device which also performs pitch shifting and cycle shifting to reduce false negatives. Positive results are reported via LoRa and/or 4G to a cloud platform and/or backend server.

Abstract: A swallowable capsule has a primary magnet along a long axis that aligns between movable electromagnets in a magnetic endoscopy machine. A flip magnet is orthogonal to the long axis. The capsule is rolled around the long axis to flip orientation of a side camera on a side of the capsule. An external base electromagnet below the patient's feet is energized to roll the capsule. The base magnet acts on the flip magnet but not on the orthogonal primary magnet when the long axis is orthogonal to a magnetic axis of the base electromagnet. Most components such as a controller, the side camera, a side laser, batteries, and an antenna, are mounted to a long Printed Circuit Board (PCB) along the long axis, while a front camera and laser are mounted to a front PCB that is mounted orthogonally to a front edge of the long PCB.

Abstract: An apparatus for virtual avatar generation is provided, including a face encoder, a face fusion engine, a voice encoder, and a voice fusion engine. The face encoder extracts first facial features from the first facial image and then encodes they into M first facial feature vectors and extracts second facial features from the second facial image and then encodes they into M second facial feature vectors. The face fusion engine generates a facial fused feature vector from the facial feature vectors, thereby generating a fused image. The voice encoder extracts first voice features from the first audio clip and then encodes they into N first voice feature vectors and extracts second voice features from the second audio clip and then encodes they into N second voice feature vectors. The voice fusion engine synthesizes a voice fused feature vector from the voice feature vectors, thereby generating a fused voice.

Abstract: Reagents A, B, C are added to an electrolyte bath for co-depositing tin-bismuth alloys (Sn—Bi). Reagent A is a larger acid molecule that binds to Bi3+ ions while reagent B is a small molecule that binds to the Bi3+ ions in spaces between the reagent A molecules. Reagents A and B reduce the standard electrode potential difference of Sn and Bi to permit co-deposition rates that yield a Sn—Bi alloy of 30-70% Bi by weight, around the 58% eutectic, with an alloy melting point below 180° C. for use as a low-temperature solder. Reagent C has a hydrophilic end that attaches to the electrode surface and a hydrophobic tail that is an aliphatic chain that attracts hydrogen gas, removing H2 gas from the electrode surface. Reagent C improves alloy microstructure by removing H2 gas generated at the cathode that can block Bi3+ ions from uniformly depositing on the surface.

Abstract: In detecting anomaly in samples, convolutional neural network (CNN) and machine-learning classifier modelled with support vectors are used. The CNN and classifier are initially trained with normal samples, and incrementally trained in retraining sessions each with self-generated anomalous samples identified in inference preceding a retraining session under consideration, thereby continually improving the anomaly-detection performance without a need to seek anomalous samples for initializing the CNN and classifier. The support vectors are selected as feature k-centers of output feature map of the CNN. Dynamic density estimation is used to determine which feature k-centers in existing support vector set are retainable in updating the support vector set in the retraining session. As such, not all feature k-centers need to be recomputed to give the support vectors in the updated support vector set. Computation effort in updating the support vector set is reduced in comparison to generating this set from scratch.

Abstract: An apparatus installed in a head-mounted display (HMD) has a coupling prism formed by packing diagonally-reflective (DR) prisms together. Each DR prism has an internal diagonal plane that is at least partially reflective. A captured image of eye or environmental scene received by a DR prism is reflected to an image-leaving end surface thereof. Image-leaving end surfaces of all DR prisms are oriented along a same direction to optically multiplex the captured images to create a multi-channel image. An imaging sensor on the coupling prism images the multi-channel image, avoiding inter-channel interference caused by spillover of captured-image signals while allowing one imaging sensor instead of multiple ones to image the captured images. A micro display displays a visible image to one DR prism, whose internal diagonal plane reflects the visible image along a direction towards an eye. Hence, the apparatus also enables image displaying to a HMD wearer.
