Abstract:
The invention discloses a copyright protection and royalty distribution method based on a NFT and its associated smart contracts. The smart contracts govern the initial minting, derivative minting, and trading of the NFT as well as the royalty distributions of every trades in the lifetime of the NFT, This method uses blockchain and NFT technology to manage and protect the copyright of digital music. The ownership and trade transaction records of the NFT are verified through blockchain technology and the distribution of digital music royalties are automated via smart contracts. According to the method of the present invention, the copyright of digital music can be made more transparent and secure, the distribution of royalties can be more just and efficient, and copyright infringement and improper resale can be avoided.
Abstract:
Certain exemplary embodiments can provide a system, which can comprise a set of electrical energy monitoring devices. Each of the set of electrical energy monitoring devices can be adapted to be mounted in a circuit breaker panel substantially adjacent to a corresponding circuit breaker. The system can comprise an energy monitoring master controller adapted to be communicatively coupled to each of the set of electrical energy monitoring devices.
Abstract:
A fingerprint identification data card and an electronic device are provided. The data card includes a case, a circuit board located in the case, an interface, and a fingerprint identifier. The case has a hole, the interface passes through the hole and the interface is connected with the circuit board, and the fingerprint identifier is disposed in the case and is connected with a processor on the circuit board in the case. It can be seen that, before using the data card, a user is required to input a fingerprint through the fingerprint identifier, and the user can use the data card only after passing authentication.
Abstract:
A text image trimming method, according to the following steps: step 1, obtaining text image data; step 2, using straight line detection method to detect the straight lines of the text image, obtaining edges of a trimmed quadrangle; step 3, detecting text on the image data, obtaining the coordinates of the boundary points of a text region; and step 4, obtaining the final trimming result according to the results of steps 2 and 3. The method can automatically detect the edges of the text region and utilize the detected text region to verify and remove unrelated redundant information thereby, allowing the user to only see the portion containing the text region useful to the user when viewing image data.
Abstract:
An inkjet offset printer includes an imaging drum and a transfix roller skewed with respect to and defining a continuously applied or an uninterrupted nip with the imaging drum to reduce torque disturbances and media wrinkling issues. Acoustic and physical disturbances resulting from a sheet of recording media entering and leaving the nip are reduced or eliminated.
Abstract:
A Universal Serial Bus (USB) connector, a USB housing, and a wireless modem are provided in the embodiments of the present invention. The USB connector includes a USB housing, a subcard, a cable, a metal terminal, and a rotating shaft assembly. The USB housing includes a bottom with a first fixing plate and a second fixing plate respectively disposed on two opposite sides. The second fixing plate is disposed with a second hole. The subcard, the first fixing plate, and the second fixing plate are disposed on a same end of the bottom. The metal terminal is disposed on a surface of the subcard. One end of the cable is connected to the metal terminal. The rotating shaft assembly penetrates the second hole.
Abstract:
The embodiments of the present disclosure provide a user device, which includes a main body part, a movable part electrically connected with the main body part, and a switching control unit and a rotation driver unit for co-axially connecting the main body part with the movable part. The switching control unit is used for eliminating a friction that enables the main body part to be fixed relative to the movable part fixed to turn on a rotation mode of the movable part. The rotation driver unit is used for applying a pre-pressing elastic force to the movable part when the switching control unit turns on the rotation mode of the movable part, so as to enable the movable part to automatically rotate relative to the main body part. The pre-pressing elastic force is less than the friction.
Abstract:
Disclosed is a method for re-skinning a third party's application. A third-party application establishes a resource file package. The resource file package includes a resource file storage path and a mapping relation between them. A subject file package is established which shares the resource file storage path. The subject file package includes resource files for presentation to be replaced. To generate a re-skinning presentation the third-party application sends the resource ID for a resource file to be presented to an operating system; the operating system obtains a corresponding resource file storage path from the resource file package according to the resource file ID; and the operating system obtains the resource file to be replaced for presentation from the subject file packet according to the resource file storage path. The resource file to be replaced for presentation is sent to the third-party application and presented to generate the re-skinning presentation.
Abstract:
A thin wall ink image receiving member enables the ink image receiving member to reach operational temperatures from a cold state more quickly than image receiving members used in previously known printers. The thin wall image receiving member includes at least one annular support member fixedly mounted against the inner surface of the cylindrical wall to enable the image receiving member to provide adequate pressure in a nip formed with a transfix roller to transfer an ink image from the image receiving member to media in the nip.
Abstract:
A calibration device and related method for a phase difference between data signal and clock signal are disclosed. An apparatus of the invention includes: an adjustable delay circuit for delaying at least one of a first input signal and a second input signal according to a delay control signal, and generating a first signal and a second signal; a phase detection circuit for detecting a phase difference between the first signal and the second signal to output a phase difference signal; a charge pump and a capacitor for outputting a control signal according to the phase difference signal; a comparison circuit for outputting a comparison result according to the control signal; and, a digital control circuit for outputting the delay control signal according to the comparison result.
