    摘要: A method for determining a direction of a spin axis of a rotating apparatus which includes an XYZ-magnetic field sensor. The method includes determining a global direction of a magnetic field; rotating the rotating apparatus around the spin axis, measuring at least one magnetic field value as a function of time with the XYZ-magnetic field sensor when the rotating apparatus is rotating about the spin axis, computing a magnetic field component of the magnetic field in a direction of a local body co-ordinate of the spin axis of the rotating apparatus from the measured at least one magnetic field value and determining a direction of the spin axis using the computed magnetic field component of the magnetic field and the determined global direction of the magnetic field.

    摘要: A particle measuring apparatus includes a charging unit to form charged particles from aerosol particles carried by an input flow, and a particle detector to provide an electric current by collecting the charged particles, wherein the charging unit in turn includes a counter-electrode having a substantially hemispherical inner portion to define a charging space, an inlet channel for guiding aerosol particles into the charging space, a corona electrode to form charged particles from the aerosol particles by generating a corona discharge in the charging space, and an outlet channel for guiding charged particles from the charging space to the detector.

    摘要: Disclosed is a method for identifying a group for digital content items. The method includes (a) retrieving one or more digital content item, (b) determining at least one characteristic of each digital content item, (c) transforming, with a first transformation method, the determined one or more digital content item to form one or more transformed digital content item, (d) determining at least one characteristic of the one or more digital content item, (e) assessing the determined at least one characteristic of the one or more digital content item with respective at least one characteristic of the one or more transformed digital content item to form a first transformation assessment result, and (f) using the first transformation assessment result to determine a group for the one or more digital content item.

    摘要: A waste collection system includes waste containers for receiving waste, sensors associated with the waste containers, a server system for receiving signals from the sensors. The server system determines that a waste container needs to be collected, determines a location of the waste container and whether the waste container is in a waste collection vehicle accessible location. A notification is sent to an operator of the waste container if the waste container is not in a waste collection vehicle accessible location. When the waste container is moved to a waste collection vehicle accessible location, an optimal waste collection strategy for a waste collection vehicle to collect waste from the waste container at the waste collection vehicle accessible location is determined and the waste collection vehicle is routed to the location of the waste container.

    摘要: Disclosed herein is a system and method for interoperability of blockchains thereby allowing use of smart contracts across blockchains in real time and in a secured manner. A plurality of blockchains are connected to each other and allow use of smart contracts written on them by other connected blockchains without the need of rewriting and/or downloading the smart contract on other blockchain. The disclosed system and methods use a distributed file system storage for secured processing of information flowing from one blockchain to other connected blockchain. Further, each connected blockchain is associated with distinct private and public key in order to encrypt and decrypt the data flowing across blockchains.

    摘要: A system for facilitating shared rendering between display devices including first display device and second display device that are communicably coupled with first computing device and second computing device, respectively. The system includes means for tracking pose of first display device, means for tracking pose of second display device, image server, first client, second client. First client is configured to: send, to image server, first information indicative of pose of first display device; receive first image frame; render first image frame at first display device; receive second information indicative of pose of second display device; send, to image server, second information; receive second image frame; and send second image frame, wherein second client renders second image frame at second display device.

    摘要: An imaging system for producing images for a display apparatus. Imaging system includes at least one imaging unit including camera, optical element including first optical portion and second optical portion having different focal lengths, and means for adjusting optical focus; means for generating depth or voxel map; and processor. Processor is configured to obtain gaze direction of user; determine optical depth of object present in region of interest within real-world scene; and control means for adjusting optical focus of imaging unit, based on optical depth of object and focal lengths of first and second optical portions, to capture warped image of real-world scene, the warped image having spatially-uniform angular resolution.
