Abstract: A movement mechanism applied to an inner-folding flexible screen terminal includes an intermediate support structure having a flexible screen support surface, left-side and right-side rotation connection structures, and left-side and right-side connecting members. Inner ends of the left-side and right-side rotation connection structures are both rotatably connected to the intermediate support structure. The left-side and right-side connecting members are respectively rotatably connected to outer ends of the left-side and right-side rotation connection structures, and are respectively slidably connected to left-side and right-side support frames. By pressing a pressing structure to the rotation structure, when a flexible screen mobile terminal is unfolded, the left and right casings can be prevented from rotating and shaking, and the unfolded state is stably maintained.

Abstract: A novel hinge and an inward-folding flexible screen mobile terminal. Each of a left structure and a right structure of the hinge includes a mechanism consisting of a push-pull rod and a fixed base and used for pushing and pulling a housing connecting member to slidably move, a rotating member, a rotating guide rail, and a rotary supporting plate; the rotating member is slidably connected to the housing connecting member; the rotating guide rail is rotatably connected to the fixed base; the outer side end of the rotary supporting plate is a rotary connecting end and connected to the housing connecting member, and the rotary supporting plate is slidably connected to the rotating guide rail, so that the rotary supporting plate can rotate together with the housing connecting member, coaxially rotate with the rotating guide rail, and slide with respect to the rotating guide rail.

Abstract: Provided in the present invention are a hinge with a lifting drive control function and an inward-folding flexible screen mobile terminal. A left structure and a right structure of the hinge each comprise a rotating member; a rotary connecting end of the rotating member is provided with a supporting portion; and the supporting portion is configured to jack, when the flexible screen mobile terminal is unfolded, lifting plates which are above the supporting portions of the left structure and the right structure. The hinge is further provided with a spring for pulling the lifting plates downwards, so that when the flexible screen mobile terminal is folded, the lifting plates descend under the action of the downward pulling force of the spring.

Abstract: A method of electing a rotating committee of byzantine fault tolerance (BFT) nodes in a decentralized computer network includes determining that a current committee of BFT nodes has outputted a predetermined number of committed transactions; identifying a plurality of candidate nodes, each respective candidate node of the plurality of candidate nodes having successfully processed, using a proof-of-work (PoW) protocol, a respective transaction of the predetermined number of committed transactions; and selecting, as a new committee of BFT nodes, a subset of the plurality of candidate nodes based on a random function.

Abstract: Disclosed is a method for processing downlink signalling of an SDN virtualization platform based on OpenFlow. The method comprises: after the preprocessing of downlink signalling is executed, further executing same, so as to judge whether more Match items also exist in a Match item list; if it is judged that more Match items also exist, acquiring an item from the Match item list; if it is judged that there are no more Match items, ending the processing; after completing the step of acquiring an item from the Match item list if it is judged that more Match items also exist, further judging whether more Action items also exist; if there are no more Action items, combining a new Action item list with the Match items to generate downlink signalling, and issuing same to a virtual network switch; and returning to the step to continue judging whether more Match items also exist; and if more Action items also exist, acquiring the next Action item.

Abstract: The present disclosure provides an overheat protection device, an overheat protection method and an electrical device. The overheat protection device is used in an electrical device and includes a transparent window unit and an optically-controlled switch. The transparent window unit is made of a transparent material and arranged on a housing of the electrical device, and an inner surface of the transparent window unit is coated with a thermochromatic material film. The optically-controlled switch is arranged inside the housing of the electrical device and exposed to an ambient light beam through the transparent window unit. The optically-controlled switch is configured to turn off the electrical device when a spectrum of the received light beam is within a predetermined spectral range.

Abstract: A password input device includes: at least two mutually separate touch display screens; a controller configured to control the touch display screen to randomly display characters; and a processor configured to determine the characters currently displayed on corresponding touch display screens subjected to a touch operation after detecting the touch operation, determine a character string inputted by a user according to a sequence of the touch operation, and take the character string as a password inputted by the user. The password input device can adopt a flexible overall arrangement mode of the character string for the password and improve the security of password input. A password input method is further disclosed.
