Abstract: A compressor includes a check valve holder and a bypass valve holder, a first through-hole in a fixed scroll, a discharge buffer chamber enclosed by the floating seal plate and the fixed scroll, and a check valve in the discharge buffer chamber. A bypass passage is formed in the fixed scroll, the discharge buffer chamber is in communication with the bypass passages, and bypass valves are disposed in the bypass passages and are movable with respect to the bypass valve holder between a third position and a fourth position; the bypass valves open the bypass passages when the bypass valves are in the third position, and the bypass valves close the bypass passages when the bypass valves are in the fourth position.

Abstract: The present disclosure provides a direct current (DC) transformer error detection apparatus for a pulsating harmonic signal, including a DC and pulsating harmonic current output module and an external detected input module, where the DC and pulsating harmonic current output module outputs a DC and a DC superimposed pulsating harmonic current to an internal sampling circuit and a self-calibrated standard resistor array; and the internal sampling circuit converts the input DC and the input DC superimposed pulsating harmonic current into a voltage signal, and sends the voltage signal to an analog-to-digital (AD) sampling and measurement component through a front-end conditioning circuit and a detected input channel. The DC transformer error detection apparatus can complete self-calibration for measurement of the DC and the pulsating harmonic signal on a test site.

Abstract: A container includes a housing that defines an interior region. Inside the interior region is a storage unit and a dispensing device. The dispensing device can receive a composition and spray or distribute the composition as desired. The dispensing device is refillable with more of the composition. The storage unit defines a chamber or interior volume in which more of the composition can be located. When the dispensing device needs to be refilled, the dispensing device can be positioned proximate to a release mechanism coupled to the storage unit, which controls how much of the composition exits the storage unit. The release mechanism can be a spigot-like structure that is manipulated by a user to release composition from the storage unit and refill the dispensing device.

Abstract: Disclosed in the present disclosure is a classification method based on skeleton lines for building shapes. The method includes: (1) expanding a template library of buildings by combining building shape classification in architecture and building shape features in real life on the basis of inheriting advantages of a traditional template matching method; (2) avoiding influence of small depressions and protrusions of the buildings on overall shapes by constructing a least-squares template; (3) extracting the skeleton lines of the buildings and calculating feature vectors of the buildings; and (4) calculating similarity between feature vectors of skeleton lines of the buildings and skeleton lines of templates by using cosine similarity, and selecting the template with the highest similarity as a classification result of the building shapes.

Abstract: A method for isolating and selecting Trichoderma Virens with an aerobic denitrification function and a method for remediating a water body with a low carbon-to-nitrogen ratio using the Trichoderma Virens are provided. Compared with the prior art, the biological treatment adopted by the present disclosure can allow the relatively-complete removal of nitrates without producing a residue, and exhibits advantages such as low cost, efficiency, and eco-friendliness. Further, the biological treatment adopted by the present disclosure can enhance the resistance of the fungus to toxic compounds and harsh environments, significantly promote the removal of nitrogen and organic matters in a water body, improve a decontamination ability of a water body, and increase the diversity of microorganisms in a water body, thereby accelerating the promotion of remediation of a water quality of a water body with a low carbon-to-nitrogen ratio. Therefore, the present disclosure has an extensive application potential.

Abstract: A method for processing cargo allocation information. including: associating a non-fungible virtual resource corresponding to a warehouse-in cargo with a wallet address of a first user identification in a blockchain network, the warehouse-in cargo comprising a cargo to be warehouse-out; obtaining warehouse-out information. the warehouse-out information comprising an identification of the cargo to be warehouse-out and a wallet address of a second user identification in the blockchain network; and, performing authorization on a transfer operation for a non-fungible virtual resource corresponding to the cargo to be warehouse-out according to the identification of the cargo to be warehouse-out, so as to perform the transfer operation by a second user terminal corresponding to the second user identification. wherein the transfer operation is an operation of transferring from the wallet address of the first user identification to the wallet address of the second user identification.

Abstract: Systems and methods directed to placing content are described. More specifically, content is received and depth information corresponding to an external environment of the computing device is obtained. An indication to associate the content with a location based on the depth information is received from a user. Information for at least one plane associated with the depth information at the location is obtained and at least a portion of the content is warped to match the at least one plane based on the depth information.
