Abstract: A stator assembly for an electric machine includes a first housing portion, a second housing portion, a stator body inserted into at least the first housing portion, a link for rotatably linking the stator body with the first housing portion, a first attachment for attaching the stator body to the first housing portion, and a second attachment for attaching the two housing portions to one another. The assembly includes an annular seal inserted axially between the stator body and the first attachment as well as between the two housing portions.

Abstract: Methods of data encryption using a mutating encryption key are disclosed. The methods generate an encryption key and utilize a codex to mutate or vary the encryption key value. The encryption key may be generated using a random number generator. The encryption key value in pre-mutation state, together with the codex, is used to generate the next valid value for the encryption key. Unencrypted message data may be used together with the codex to mutate the encryption key. A valid encryption key and the unencrypted or successfully deciphered message are thus required to mutate the encryption key to the next key post-mutation state at each end.

Abstract: A method and system for converting database applications into blockchain applications is disclosed. Multiple applications on different nodes can automatically perform global data consensus to prevent data conflicts using the embodiments described. One method involves monitoring databases as they is modified by database applications, to extract data operations from transaction logs, convert the data operations to a general format, and activate the smart contract on the blockchain to complete the data consensus check at multiple nodes. Each node monitors the blocks on blockchain and synchronizes the data back to database. In the case of conflicting data, the data is not able to pass consensus and synchronize with the other nodes in the blockchain. The local nodes automatically roll back when detecting invalid data.

Abstract: A system for implementing distributed blockchain transactions that includes: a first participant blockchain comprising a first node; second participant blockchain comprising a second node; and a coordinator blockchain comprising a coordinator node is disclosed. The distributed transaction involves a first transaction on the first participant blockchain, and a second transaction on the N second participant blockchain.

Abstract: This patent describes a complete blockchain email system that supports both internal and cross-chain emails with the potential to interact with non-blockchain email systems. Through this method, as long as the sender or the recipient of the email is a blockchain mailbox, the email information will be recorded in the blockchain to ensure the authenticity of the email. Moreover, when blockchain mailboxes exchange messages, the email information will be encrypted and stored in distributed storage where only the recipient can obtain the unique cypher key and storage location of the email, thereby ensuring the security of email transmissions.

Abstract: A method for generating fair and effective random numbers for smart contracts, which effectively mitigates certain problems associated with conventional methods while achieving verifiable and non-tamperable random number generation is disclosed. The concept behind the disclosed method treats miners as being not trustworthy, and presumes that the number of miners in the blockchain is limited. With sufficient motivation, miners can reach a consensus to manipulate the block. The goal is thus to create a verifiable fair Random Number Generator. Under this condition, as long as at least one of the parties to the smart contract is credible and does not misuse the confidential information, a trusted blockchain random number can be generated. After the last disclosure of the random number, the verification signature submitted by parties to the contract can be used to confirm that the random number calculation process is credible.

Abstract: A device and method for using biometric technologies to ensure secure transactions using blockchain technology are disclosed. The embodiments described mitigate at least some security related problems in conventional blockchain digital wallets, particularly those that cannot reliably authenticate user identity. The present disclosure presents a method and apparatus for using authentication and data protection for implementing a blockchain offline wallet using biometrics.

Abstract: The disclosed embodiments provide an improved method for enabling consumers to identify and purchase a desired frame that is captured in an image. For example, in one embodiment, the disclosed embodiments include a frame recognition system that includes at least one processor for executing computer executable instructions for receiving an image; identifying a frame image from the image; performing image recognition using the frame image to identify a plurality of frames; retrieving merchant information corresponding to the plurality of frames; receiving merchant information associated with the plurality of frames; presenting the plurality of frames and the merchant information associated with the plurality of frames; receiving order information in response to a user ordering a frame from the plurality of frames; and processing the order information.

Abstract: Conversational Super Bots are provided. A SuperBot may utilize a plurality of dialogs to enable conversation between the SuperBot and a user. The SuperBot may switch between topics, keep state information, disambiguate utterances, and learn about the user as the conversation progresses using each of the plurality of dialogs. Users/developers may expose a number of dialogs each specializing in a conversational subject as a part of the SuperBot. The embodiments provide enterprise systems that may handle multiple subjects in one conversation. SuperBot architecture allows dialogs to be added to the SuperBot and managed from the SuperBot. Dialog intelligence delivery via the SuperBot is decoupled from the authoring of the dialogs. Processes that make the SuperBot appear as intelligent and coherent to a user are decoupled from the dialog authoring. Developers may develop dialogs without considerations of language processing. The SuperBot includes components that manage and coordinate the dialogs.
