Abstract: A refrigerator is provided and includes a refrigerator body, a door body, an ice making apparatus and a controller. The refrigerator body includes a storage compartment. The door body is pivotally connected to the refrigerator body to open or close the storage compartment. The ice making apparatus includes a plurality of ice makers. The controller is configured to control at least one of the plurality of ice makers to make ice according to an ice making request.

Abstract: Disclosed is a decision method of condition-based maintenance to a power grid risk. The method includes: calculating a contribution of each device to be maintained of a plurality of devices to be maintained to the power grid risk in a current operation mode of a power grid, and determining the contribution of the each device to be maintained to the power grid risk as a set value corresponding to the each device to be maintained; determining a maintenance decision order of the devices to be maintained according to a descending order of set values corresponding to the devices to be maintained; and sequentially making maintenance decisions on the devices to be maintained according to the determined maintenance decision order.

Abstract: The present invention relates to a control circuit of a high-definition naked-eye portable stereoscopic video player and a stereoscopic video conversion method which enables the user to watch a stereoscopic video without wearing the stereoscopic glasses, wherein the control circuit includes a power supply. An HD video CH1 and an HD video CH2 are connected to the signal input terminal of a respective HDMI decoder through a respective HDMI plug interface, the signal output terminal of the HDMI decoder is connected to the signal input terminal of an FPGA programmable logic device. A DDR2 memory, a SRAM Static Random Access Memory, and a FLASH memory bi-directionally exchange data with the FPGA programmable logic device.

Abstract: The present invention relates to a light path layout structure of a high-definition naked-eye portable stereoscopic video display and a light path circuit which enables the user to watch a stereoscopic video without wearing the stereoscopic glasses. Two video signals that are output from the stereoscopic video playing circuit board are synchronously displayed on a left liquid crystal display screen and a right liquid crystal display screen respectively. Sights from the left eye and the right eye of a person pass through a left eyepiece and a right eyepiece to a left eye reflector and a right eye reflector respectively. Images played on the left liquid crystal display screen and the right liquid crystal display screen are viewed via the left eye reflector and the right eye reflector respectively.

Abstract: A structure of left and right viewing mirrors of high-definition naked-eye portable stereoscopic video player, wherein the left viewing mirror (2-1) and the right viewing mirror (2-2) form an angle of 90 degrees. This structure realizes that the display surface of a left liquid crystal display screen (3-1) and the display surface of a right liquid crystal display screen (3-2) form an angle of 45 degrees with the left viewing mirror (2-1) and the right viewing mirror (2-2), which reduces the size of the player, and is easy to carry. Also, the goal of high-definition naked-eye viewing of stereoscopic video images is achieved.
