  • Patent number: 12257875
    Abstract: A void bushing for a vehicle suspension is configured to have protrusion parts formed to protrude outwards on a bulge part of an inner pipe. The protrusion parts are located to be disposed in oblique line directions between void portions of an elastic body that is filled between the inner pipe and an outer pipe. In the void bushing, ride comfort characteristics and durability characteristics of a vehicle may be maintained, as they are, under favorable conditions by the void portions. Further the handling response characteristics of the vehicle may be advantageously improved by promoting a rigidity increase through the protrusion parts.
    Type: Grant

  • Patent number: 7113764
    Abstract: A method for transmitting an emergency call of a mobile phone includes the steps of: receiving position recognition information from a base station via a forward channel in roaming a mobile terminal; varying a search position on an emergency call mapping table previously stored in a memory according to the received position recognition information; and transmitting a call by a phone number set on the varied search position when an emergency call needs to be transmitted. With this method, even though the user is not aware of the emergency call number of a country or an area where he uses his mobile phone to make an emergency call or even though he or she is not aware of a one-touch dial number or a manual for making a call, the user can easily make an emergency call. Moreover, by linking the read address of the phone book, in which the emergency call number has been stored, to the key for making an emergency call, making an emergency call can be promptly performed automatically by one-time key manipulation.
