Abstract: A fully-automated sushi making apparatus, comprising a fixed plate (1), a container module (2), an annular shielding module (3), a center shielding module (4), a dispensing module (7), a ring-shaped isolation module (5), a cylindrical pushing module (6), an extraction module (8), a recovery module (9), and a controller (10). The controller controls vertical drive units (52, 62, 81) and horizontal drive units (31, 41, 51, and 61) to drive the connected annular shielding module, ring-shaped isolation module, and cylindrical pushing module to perform layerwise removal of rice from the container module, then drives the center shielding module, the dispensing module, and the cylindrical pushing module to add sushi ingredients into the hollow center of the rice removed from the container module, and finally drives the extraction module, the annular shielding module, and the center shielding module to move in unison to extract the completed sushi.

Abstract: A composite motor having high-precision positioning, comprising: a housing (1), a rough positioning assembly, a hollow output shaft (2), a fine positioning assembly, a power switching apparatus and a controller (6). A stepper motor (3) in the rough positioning assembly is responsible for rough positioning of the composite motor, an annular travelling wave ultrasonic motor in the fine positioning assembly is responsible for tail end fine positioning of the composite motor, and the controller (6) implements power output switching between the annular travelling wave ultrasonic motor and the stepper motor (3). The composite motor effectively solves the problem that annular travelling wave ultrasonic motors which operate continuously for a long time have a short service life, and ensures high-precision positioning while also extending motor service life.

Abstract: The present disclosure relates to a multirotor unmanned aerial vehicle, comprising a fuselage, being provided with at least one support arm in a transverse penetrating manner, and a rotor, being disposed at each end of the support arm in a transverse tilting manner. When the unmanned aerial vehicle moves transversely, the tilting rotors can provide lift force for keeping the unmanned aerial vehicle at certain altitude and also provide power for transverse movement of the unmanned aerial vehicle, and meanwhile, the fuselage does not need to tilt, so that the unmanned aerial vehicle has the advantages of high response rate and high flight speed.

Abstract: A device may determine that a user device should be authenticated; and determine a confidence measurement based on an established activity pattern of the user device. The confidence measurement may relate to a likelihood that an authorized user of the user device is in possession of the user device. The device may authenticate the user device based on the confidence measurement.

Abstract: A method for measuring a relative content of Gram-negative bacteria in an active sludge, the method including: 1) breaking zoogloeas in the active sludge; 2) isolating 2-keto-3-deoxyoctonic acid (KDO) from free bacteria and cell debris; 3) performing fluorescence labeling on the isolated KDO to obtain a fluorescent derivative; and 4) isolating the fluorescent derivative by high performance liquid chromatography (HPLC) and conducting quantitative measurement by fluorescence to obtain the relative content of the Gram-negative bacteria in the active sludge.

Abstract: A user device may identify a received a signal indicating an incoming call; determine that another user device has answered the call; generate call log information that indicates that the other user device has answered the call; and store or output the generated call log information. Additionally, or alternatively, a set of user devices may receive a ring signal indicating an incoming call; a particular user device, in the set of user devices, may answer the call; and another user device, in the set of user devices, may store a unified call log. The unified call log may indicate that the particular user device answered the call, and may further indicate that the other user device did not miss the call.
