Thin, lightweight, flexible, bright, wireless display

A multilayered thin, lightweight, flexible, bright, wireless display having components capable of being manufactured by a printing method. A flexible substrate provides a support structure upon which components can be manufactured by a printing method. A display stratum includes light emitting pixels for displaying information. The light emitting pixels are formed by printing a pixel layer of light-emitting conductive polymer. An electronic circuit stratum includes signal transmitting components for transmitting user input signals to a display signal generating device for controlling display information transmitted from the display signal generating device. Signal receiving components receive the display information transmitted from the display signal generating device. Display driving components drive the display layer according to the received display information. A user input stratum receives user input and generates the user input signals. A battery stratum provides electrical energy to the electronic circuit stratum, the user input stratum and display stratum components. The signal receiving components may include first radio frequency receiving components for receiving a first display signal having first display information carried on a first radio frequency and second radio frequency receiving components for receiving a second display signal having second display information carried on a second radio frequency. The display driving components may include signal processor components for receiving the first display signal and the second display signal and generating a display driving signal for simultaneously displaying the first display information at a first location on the display stratum and the second display information at a second location on the display stratum. At least some of the components in the battery, display, user input and electronic circuit stratums are formed by printing electrically active material to form circuit elements including resistors, capacitors, inductors, antennas, conductors and semiconductor devices.

System and method for real-time graph data processing based on BSP (Board Support Package) model

The invention relates to a system and method for real-time graph data processing based on a BSP (Board Support Package) model. The system comprises a data storage unit, a graph data inquiring and counting unit and a graph data analyzing and processing unit, wherein the data storage unit is used for preprocessing graph data, storing the graph data according to a memory storage-distributed memory storage-distributed file system three-layer storage structure and generating an operation based on the graph data, the graph data inquiring and counting unit is used for inquiring and counting the graph data, decomposing the operation generated by the data storage unit into a plurality of tasks, distributing the tasks to corresponding calculating nodes in an equalized manner, carrying out statistics on all task calculation results, combining all the task calculation results and returning the combined task calculation results serving as a final result to users, and the graph data analyzing and processing unit is used for enabling all the calculating nodes to execute the decomposed tasks through iterative calculation, realizing the synchronization of iterative calculation of each time through message passing and outputting the task calculation results. The method is used for realizing the real-time graph data processing based on the system. The system and the method have the advantages that the access efficiency is high, the cluster load balancing is kept, the execution efficiency of the BSP model is accelerated, and the like.

Block chain-based method for accessing power Internet of Things terminal

The invention provides a Block chain-based method for accessing a power Internet of Things terminal, comprising the steps of: connecting a to-be-accessed power Internet of Things terminal to a masternode, and initiating an authentication request; the master node responding to the authentication request, and randomly selecting nodes that meet the condition of a threshold number from the block chain to form an authentication group; encrypting a public key G and an identity ID of the to-be-accessed power Internet of Things terminal by using a private key to obtain a digital signature ciphertextX, and sending the identity ID, a terminal public value R and the digital signature ciphertext X to the master node; the master node encapsulating and sending the authentication request information toa member node of the authentication group; the authentication group running PBFT consensus algorithm, and obtaining an authentication result by performing distributed authentication through two-two exchanging of the authentication information between the nodes of the authentication group; generating a new block in the block chain, and returning confirmation information to the to-be-accessed powerInternet of Things terminal; and the power Internet of Things terminal returning encrypted confirmation information to an access gateway. The block chain-based power Internet of Things terminal access method can improve the security and efficiency of authentication.
