Abstract: A massager useful for massaging a user's back muscle is disclosed. The massager comprises a body having a first end extending along a first axis and a second end extending along a second axis. The first end adapts a massage head. The second end adapts a handle. The handle extends along the second axis and comprises a bend angle such that the user may hold the handle to massage his back muscle with the massage head without an assistance of a masseur.

Abstract: Provided is a method of reconstructing multi-source long-time-series night light data and a system thereof, relating to the field of reconstructing ecological remote sensing data. Based on night light images of a first-generation satellite DMSP/OLS (Defense Meteorological Satellite Program/Operational Line-scan System) and a second-generation satellite NPP/VIIRS (National Polar-orbiting Partnership/Visible Infrared Imaging Radiometer Suite), a method of reconstructing a set of long-time-series night light data products is developed. Since satellite images that two generations of satellites have at the same time in a certain year use an inverse hyperbolic sine transform to fit NPP/VIIRS in 2013 into a data form of DMSP/OLS, and obtain an optimal fitting equation, thus producing a set of long-time-series data products from 1992 to 2021. The method can solve a fault problem between two generations of light data of DMSP/OLS and NPP/VIRS, and improve the accuracy of data reconstruction.

Abstract: Techniques are described for reducing capacity fragmentation by using an Automatic Defragmentation Service (ADS). More particularly, hypervisors (HVs) that are candidates to defragment are identified, an HV to defragment is selected, and one or more VM instances are migrated from the selected HV to a different HV. According to certain implementations, instead of migrating a VM to a new HV, the VM is live migrated to an existing HV.

Abstract: The present invention relates to a pharmaceutical composition comprising a ?-lactam compound of formula (I), or a stereoisomer, a solvate or a pharmaceutically acceptable salt or ester thereof, and a lactamase inhibitor or an efflux pump inhibitor, and the use thereof for inhibiting microorganisms, particularly bacteria, especially Gram-negative bacteria, wherein each symbol in formula (I) is as defined in the description.

Abstract: A method may include identifying a target view of a video stream, obtaining a target exposure value for the target view, after obtaining the target exposure value, initiating a transition to the target view with the target exposure value from an initial view having an initial exposure value, and transitioning the video stream to the target view using the target exposure value.

Abstract: Methods and systems for synthesizing multicompartment capsules are disclosed, as well as multicompartment polymer capsules formed in accordance with disclosed techniques. At least one plurality of polymer capsules are formed via a capsule-forming process. A feed solution and a reservoir solution are provided, each comprising a biopolymer. The feed solution biopolymer and the reservoir solution biopolymer have opposite charges. Droplets of the feed solution are introduced into the reservoir solution, thereby forming via electrostatic complexation a plurality of polymer capsules. At least a portion of the resulting polymer capsules are then encapsulated in a larger polymer capsule via a similar process, wherein the feed solution utilized for the encapsulation process also comprises the formed smaller capsules.

Abstract: A method may include obtaining a frame of a video stream of multiple video streams of a video conference, obtaining face detection information identifying a face size and a face position of at least one face detected in the frame, and cropping and scaling the frame according to at least one crop and scale parameter using the face detection information to obtain a modified first frame. The at least one crop and scale parameter is based on frames of the multiple video streams. The frames include the frame. The method may further include presenting the modified frame.

Abstract: An electrified vehicle and associated inverter configured for powering two different types of external loads include first and second phase/line legs combined with a first neutral leg coupled to a vehicle chassis, and a second floating neutral leg that is not coupled to the vehicle chassis. The first/second phase legs and first neutral leg are coupled to a first receptacle configured to receive a corresponding plug to power a first load, such as a power tool or accessory. The first/second phase legs and the second neutral leg are coupled to a second receptacle configured to receive a corresponding plug to power a second load, such as a home or building having an earth grounding electrode. The inverter may include an isolation transformer between the loads and the traction battery, and/or may be configured to provide single phase, split-phase, or three-phase power for either or both of the neutral connections.

Abstract: A method (1000) for operating cameras (202) in a cascaded network (100), comprising: capturing a first view (1200) with a first lens (326) having a first focal point (328) and a first centroid (352), the first view (1200) depicting a subject (1106); capturing a second view (1202) with a second lens (326) having a second focal point (328) and a second centroid (352); detecting a first location of the subject (1106), relative the first lens (326), wherein detecting the first location of the subject (1106), relative the first lens (326), is based on audio captured by a plurality of microphones (204); estimating a second location of the subject (1106), relative the second lens (326), based on the first location of the subject (1106) relative the first lens (326); selecting a portion (1206) of the second view (1202) as depicting the subject (1106) based on the estimate of the second location of the subject (1106) relative the second lens (326).

Abstract: A method of tracking a presenter during a videoconference, comprising: detecting, in a data stream, data indicating a presence of one or more persons at a videoconferencing endpoint, the data stream comprising a plurality of frames; detecting tracker initiation data (e.g., that a person is actively talking, or that a person has raised their hand, or both) in the data stream; determining a subject of interest responsive to the tracker initiation data, and tracking the subject of interest as they move while making a presentation.
