Abstract: The present disclosure provides a curvature determination method, a curved display panel, and a display device. The curvature determination method includes: establishing a first association relationship between deflection and a shear stress of the curved display panel in a first direction, the first direction being a bending direction of the curved display panel; determining a constraint condition for the shear stress in accordance with an influence of the shear stress on a light leakage of the curved display panel; and generating a curvature change relationship of the curved display panel in the first direction in accordance with the first association relationship when the constraint condition has been satisfied.

Abstract: A digital printing machine comprises a cylindrical drum assembly on the rigid printing framework. A cylindrical drum moves along and rotates about its central cylindrical axis and a stationary printing head with multiple nozzles placed proximately above the circumference of the cylindrical drum. The combined linear and rotational movements of the cylindrical drum enable the printing head to create a smooth helical printing trajectory on the flexible fabrics. The cylindrical drum of the digital printing machine also works as a working drum to hold a piece of flexible textile to be printed. A double-side printing mechanism allows the digital printing machine to automatically carry out the second side printing.

Abstract: An information processing method, a server, and a computer storage medium are disclosed. The method includes: obtaining first information from a first terminal, the first information including at least information content and an information presentation style parameter; obtaining second information from the second terminal, the second information including at least basic user information and/or user behavior information and/or user relationship chain information; generating sampling information according to the first information and the second information, and constructing, according to the sampling information, at least one processing policy that separately corresponds to a first type of processing node interacting with the first terminal and a second type of processing node interacting with the second terminal; and generating the third information according to the first information and the at least one processing policy, and sending the third information to the second terminal for information presentation.

Abstract: A pet food dispenser comprising a lid and a hopper bin. The lid fits over a loading opening of the hopper bin. A main section includes a base, and the main section includes a base cover having a hopper funnel and a hopper recess. An auger assembly has an intake opening and an output opening, and the auger assembly is removably cradled in the hopper recess. When the auger assembly is operating, an auger blade is formed as a helical screw that drives articles from the intake opening to the output opening. A motor mount has a motor, and the motor is mechanically connected to the auger assembly to drive the auger assembly. The motor mount is connected to the base. A microprocessor controls actuation of the motor.

Abstract: The present invention provides a Christmas tree stand that is self-watering and rotatable. The self-watering system, that rotates with the tree, mainly includes a water reservoir, a hose, a water tank that holds on to the lower end of the tree, and a valve mechanism that automatically keeps the water in the water tank at optimum level. A rotatable tank assembly is driven by an electric drive motor on a stationary support assembly. Electrical power is passed from the stationary support assembly to the rotatable tank assembly through a slipping-ring connector. In the preferred embodiment, a remote control is provided to supply power for rotation of the rotatable tank assembly, including the tree, and the power receptacle on the rotatable tank assembly for suitable electrical loads, e.g., decorative lights, separately.

Abstract: A temperature controlled compartment apparatus in the form of a kitchen drawer mounted in an interior compartment that is cooled by one or more thermoelectric heat pump modules in the rear portion of a housing surrounding the drawer. A fan circulates air from the drawer past each thermoelectric heat pump module for cooling the air for the drawer and another fan or fans circulates external air past each thermoelectric heat pump module for removing heat from each module by that external air.

Abstract: A temperature controlled compartment apparatus in the form of a kitchen drawer mounted in an interior compartment that is heated or cooled by one or more thermoelectric heat pump modules in a housing surrounding the drawer. A fan circulates air from the drawer past each thermoelectric heat pump module for either heating or cooling the air for the drawer and another fan or fans circulates external air past each thermoelectric heat pump module for cooling or heating, respectively, that external air. Heating or cooling is selected by selecting the polarity of the DC electric source provided to each thermoelectric heat pump module.

Abstract: An air jet system is provided that includes a refrigerated display case. The novel apparatus includes a glass display window, which is transparent and has an outer surface for viewing the contents of the display case. The unit also has a front bar that defines an air passage therein when connected to a bracket and also defines a channel at one of its ends which has at least one opening. The bracket connects and supports the display window and the front bar on the display case. A nozzle is positioned in the channel and has holes therein for air passage and is positioned to direct air through the opening in the end of the front bar and onto the outer surface of the display window. A centrifugal blower is connected to the bracket and is adapted to blow air through the air passage and through the holes in the nozzle so that air is guided over the outer surface of the glass display window to eliminate moisture condensation.
