Abstract: Disclosed are a decoquinate liposome, a preparation method therefor and a use thereof. The preparation raw materials for the decoquinate liposome comprise the following components in parts by weight: 1 part of decoquinate and 2-20 parts of lecithin. The liposome is stable, shows favorable malaria resistance effects in-vivo and in-vitro with respect to animal bodies, can be used for quickly relieving the conditions of malaria, particularly subtertian malaria, and is safe. The preparation method is simple and feasible, and has the potential for mass production.

Abstract: This application relates to a tab flattening device. The tab flattening device includes: a roller configured to convey an electrode plate, a cover, and a flattening portion. The surface of the roller is in contact with the electrode plate in a contact region. The cover surrounds the contact region peripherally and includes a feed-in guide surface oriented toward the contact region. The flattening portion is disposed protrusively on the feed-in guide surface, and located opposite to a tab of the electrode plate. A tab guide surface is formed on the flattening portion. Along a feed-in direction of the electrode plate, the flattening portion is at least partially located upstream of the contact region.

Abstract: This application is directed to a speaker assembly in which a speaker is mounted in an enclosure structure. The enclosure structure exposes a speaker opening of the speaker and provides a sealed enclosure for a rear portion of the speaker, and further includes an electrically conductive portion. One or more electronic components are coupled to the electrically conductive portion of the enclosure structure (which is grounded in some implementations). The electrically conductive portion of the enclosure structure is configured to provide electromagnetic shielding for the electronic components and forms part of the sealed enclosure of the speaker. In some implementations, the electrically conductive portion of the enclosure structure is thermally coupled to the electronic components and acts as a heat sink that is configured to absorb heat generated by the electronic components and dissipate the generated heat away from the electronic components.

Abstract: In a display assistant device, a display panel assembly has a plurality of first retention elements, and each first retention element is formed on a rear surface of the display panel assembly and adjacent to a respective first edge of the display panel assembly. A back cover is configured to hold the display panel assembly using a plurality of second retention elements. Each second retention element is arranged adjacent to a respective second edge of the back cover. When mated to each other, the first and second retention elements are configured to control an in-plane displacement of each second edge of the back cover in response to an impact of a force on the second edges, thereby limiting an out-of-plane displacement of each second edge of the back cover and protecting the first edges of the display panel assembly from falling apart from the second edges of the back cover.

Abstract: This application is directed to a display assistant device that acts as a voice-activated user interface device. The display assistant device includes a base, a screen and a rear speaker. The base is configured for sitting on a surface. The screen has a rear surface and is supported by the base at the rear surface. A bottom edge of the screen is configured to be held above the surface by a predefined height, and the base is substantially hidden behind the screen from a front view of the display assistant device. The rear speaker is concealed inside the base and oriented to project sound towards the rear side of the base.

Abstract: A mobile wireless communications device may include first and second housings coupled together and moveable between first and second positions. The mobile wireless communications device may also include wireless transceiver circuitry carried by at least one of the first and second housings, a magnetic sensor carried by the first housing and coupled to the wireless transceiver circuitry, and a magnet carried by the second housing. The mobile wireless communications device may also include a magnetically conductive body operatively coupled between the magnetic sensor and the magnet when the first and second housings are in the first position.
