Abstract: A structure comprises at least one outer wall having an internal wall section and an outer wall section with an air flow passage therebetween. A circulation system circulates air through the flow passage to inhibit moisture accumulation and mold growth. A sensing system determines the presence of moisture in the flow passage and generates a signal in response thereto. A controller receives the signal from the sensing system and controls the circulation system to maintain a predetermined temperature and relative humidity in the flow passage.

Abstract: A hair dryer includes a housing having a main air inlet, a main air outlet and a main interior volume between the main air inlet and the main air outlet. The housing has an auxiliary air inlet, an auxiliary air outlet, and an auxiliary interior volume between the auxiliary air inlet and the auxiliary air outlet. The auxiliary air inlet, the auxiliary air outlet and the auxiliary interior volume each are outside of the main interior volume so that the auxiliary air inlet and the auxiliary air outlet are not in communication with the main air inlet and the main air outlet. A first pair of ion emitters are in the main interior volume. A second pair of ion emitters are in the auxiliary interior volume. A fan is upstream of the first pair of ion emitters in the main interior volume, and selectively generates a main airflow through the housing from the main air inlet to the main air outlet. A heater is in the main interior downstream of the fan and upstream of the main air outlet relative to the main airflow.

Abstract: Systems and methods for correcting spinal deformity utilize a dynamic, multi-structure torso orthosis that allows motion during wear. The disclosed embodiments utilize a series of elastically coupled ring structures that conform to the circumference of the torso of a patient. Adjustable elastic coupling mechanisms are utilized to create and alter forces and moments that are applied to the torso through these ring structures. In some instances, the ring structures are formed from individual elements that can be linked to accommodate particular anatomies. In other instances, a superior ring structure can be configured to accommodate the patient's upper torso.

Abstract: The disclosure herein describes using a transcript generation model for generating a transcript from a multi-speaker audio stream. Audio data including overlapping speech of a plurality of speakers is obtained and a set of frame embeddings are generated from audio data frames of the obtained audio data using an audio data encoder. A set of words and channel change (CC) symbols are generated from the set of frame embeddings using a transcript generation model. The CC symbols are included between pairs of adjacent words that are spoken by different people at the same time. The set of words and CC symbols are transformed into a plurality of transcript lines, wherein words of the set of words are sorted into transcript lines based on the CC symbols, and a multi-speaker transcript is generated based on the plurality of transcript lines. The inclusion of CC symbols by the model enables efficient, accurate multi-speaker transcription.

Abstract: A method for video encoding includes determining a corresponding motion vector for each of multiple control points of a base predictor. The method further includes determining a corresponding motion vector difference for each of the multiple control points of the base predictor based on the determined motion vector for each respective control point. The method further includes generating prediction information of the current block to be included in a coded video bitstream. The prediction information includes (i) a usage flag indicative of the affine merge mode with offset, (ii) offset parameters defining the determined corresponding motion vector difference for each of the one or more of the control points, and (iii) a zero motion vector difference flag for the multiple control points of the base predictor. The zero motion vector difference flag indicates whether offset parameters for the respective control point are provided in the prediction information.

Abstract: Snap rings, assemblies, and methods are provided for retaining a component on a shaft. The snap ring includes an annular body defining an opening through a center thereof, defining an outer curved surface and an inner curved surface, having a first end and a second end spaced apart from each other to define a gap therebetween, and having a first circumferential edge and a second circumferential edge spaced apart from each other to define a circumferential opening slit extending from the first end to the second end. The snap ring is configured to be received within a continuous, circumferential mating groove formed in an exterior surface of the shaft, and to retain the component in a fixed position when the component is located on the shaft and the snap ring is located in the mating groove.

Abstract: A system for performing background and floor replacement in full-length subject images is described. A set of three or more images of a subject can be captured under different illumination conditions. For example, at least one of the images is captured while a foot portion of the subject and surrounding floor, including a floor mat on which the subject is positioned, are illuminated by a floor lighting device. The floor mat has a Lambertian surface to reflect light in a particular manner such that a maximum contrast between the floor and the subject is captured in the image. Varying contrast between the background, floor, and subject among the images of the set can be leveraged by an image processing system to generate a background mask and a floor mask that are combined and seamlessly transitioned to yield a compiled mask for use in background and floor replacement.
