  • Patent number: 10300532
    Abstract: A clamp for a tool holder is disclosed. The clamping tool holder includes a body having an insert-receiving pocket and a threaded clamp-receiving bore with a coolant opening for receiving pressurized coolant from a coolant source. A clamp includes a threaded aperture extending from a top surface to a bottom surface and coolant passages in fluid communication with a coolant header. A clamp screw is threaded into the threaded aperture of the clamp. The clamp screw includes a plurality of coolant passages in fluid communication with the coolant opening of the body, and at least one coolant channel in fluid communication with the coolant passage. Coolant from the coolant source enters the coolant opening of the body, travels into the clamp screw, travels into each coolant passage of the clamp, and then exits the clamp in a direction toward a cutting insert-workpiece interface.

  • Patent number: 8320540
    Abstract: The present disclosure provides a method and a system for verifying identity of a user and a system for generating and maintaining verification codes. The method and the system use system-generated caller numbers as verification codes. When an application system needs to verify the identity of a user, the verification system generates a caller phone number and uses a communication switching system to place a call originating from the caller phone number to the user's phone. The user's phone has a caller ID display function to automatically display the caller number, which serves as a user identity verification code. The user provides the received caller number to the application system for user identity verification. No text messaging or other ways of communication is required. The method and the system can achieve reliable user identity verification. A centralized system may support multiple application systems for user identity verification.

  • Patent number: 7992068
    Abstract: In a transmitter, a standard stream of encoded multi-media data and uniform error correction data is transmitted through a first channel. The uniform error correction data provides substantially the same error correction for all portions of the encoded multimedia data. Simultaneously, additional unequal error correction data is generated for critical portions of the standard stream and not for other portions of the standard stream, and the additional error correct data is transmitted through a second channel. In a receiver, the additional error correct data is used to error correct just the critical portions of the standard stream, and then the uniform error correction data is used to error correct all the portions of the encoded multimedia data of the standard stream.
