  • Patent number: 11993107
    Abstract: Proposed is a tire with self-generation and sound absorption and, more particularly, is a tire with self-generation and sound absorption that operates an electronic module through self-power generation and has improved sound absorption performance. The tire with self-generation and sound absorption includes: a wall structure formed on a surface of an inner liner of the tire; a sound absorber spaced apart upward from the inner liner with both ends coupled to the wall structure and blocking sound generated by surfaces of treads and a road surface; and an electronic unit disposed on the surface of the inner liner and positioned between the inner liner and the sound absorber.

  • Publication number: 20190263185
    Abstract: The present invention relates to a pneumatic tire, and more particularly, to a pneumatic tire having an improved decoupling groove in a shoulder. The pneumatic tire including a tread (100), a sidewall (200), and a bead (300) includes one or more side ring decoupling grooves (400) formed along the circumference of the tire at an upper portion of the sidewall (200), and the side ring decoupling grooves (400) are formed in a direction parallel with the ground coming into contact with the tire while the tire runs.

  • Patent number: 7330595
    Abstract: A system and method perform video data compression in a manner that limits the need for external memory access. Accordingly, the operational frequency of the local data bus is reduced and power consumption is therefore minimized. In this manner, the present invention is especially amenable to use in mobile systems.

  • Publication number: 20010051896
    Abstract: The present invention relates to a system for an electronic mail enclosing a gift coupon and its transmitting method. A sender who intends to send an e-mail is connected to a Web server that offers an e-mail service and writes an e-mail message. A sender who has written an e-mail message transmits the message enclosing a gift coupon given a lottery number to a recipient. The recipient checks the e-mail and accepts receipt of the gift coupon. Related information of the recipient who accepts receipt of the gift coupon is stored in a database of a gift coupon providing server. The gift coupon providing server informs the recipient as to whether he or she has won a gift.
