  • Patent number: 11000501
    Abstract: The present invention relates to a pharmaceutical composition for prevention or treatment of neurological diseases and mental diseases, the composition containing syringaresinol. The syringaresinol according to the present invention has an effect of reducing excitatory synaptic transmission in a central nervous system and an effect of suppressing epilepsy and activity of animals. This suppressive effect of the excitatory synaptic transmission may be effectively used for the prevention and treatment of all neurological diseases and mental diseases resulting from synapse dysfunction and synpatic excitatory-inhibitory transmission imbalance.

  • Patent number: 8185739
    Abstract: In one embodiment of the present invention, a method includes authenticating an HDCP transmitting device at a first port of an HDCP receiving device. A port of the HDCP receiving device is connected to a pipe of an HDCP architecture of the HDCP receiving device at a first time. A synchronization signal is received from the HDCP transmitting device at the port of the HDCP receiving device at a second time. A loss of synchronization between the HDCP transmitting device and the HDCP receiving device is detected when the time-span between the first time and the second time is not greater than the period of time between synchronization signals sent from the HDCP transmitting device. A re-authentication is initiated between the HDCP transmitting device and the HDCP receiving device in response to detecting the loss of synchronization.
