  • Patent number: 11612007
    Abstract: The present invention discloses a low power dissipation Bluetooth mesh network system and a communication method thereof. The Bluetooth mesh network system includes a friend node and a lower power node. The friend node operates as a proxy server terminal to perform a proxy server broadcast. The lower power node operates as a proxy client and establishes a connection with the friend node based on a proxy protocol when the proxy server broadcast is received and identified. The friend node further filters out an invalid packet unrelated to the low power node and stores a valid packet related to the low power node so as to transmit the valid packet to the low power node when the low power node switches from a sleep status to a wakeup status.

  • Patent number: 10671526
    Abstract: An electronic computing device, a method for adjusting the trigger mechanism of a garbage collection function, and a non-transitory computer readable storage medium thereof are provided. A storage unit of the electronic computing device stores a whitelist. The whitelist records a plurality of data sets, wherein each of the data sets has a name of an application and an offset value of the application. A processor of the electronic computing device executes a system program. The system program loads the whitelist into a memory during a initialization procedure. The system program detects that a specific application is triggered and retrieves the offset value of the specific application from the whitelist in the memory according to the name of the specific application. The system program forks a process to the specific application and updates a threshold of a garbage collection function according to the offset value.

  • Publication number: 20020107360
    Abstract: Antigens are provided which are derived from the enterically transmitted non-A/non-B viral hepatitis agent, known as hepatitis E virus (HEV). The HEV antigens and in particular, soluble species of the capsid protein encoded by the carboxy terminal region of HEV ORF2, are immunoreactive with sera from individuals infected with HEV. In one embodiment, these antigens may be produced by a baculovirus expression vector and form virus-like particles (VLPs). The antigens are useful as diagnostic reagents in diagnostic methods and kits for determining infection of an individual with HEV. The antigens are also useful in vaccine compositions effective in methods for preventing HEV infection.

  • Patent number: 6291641
    Abstract: Antigens are provided which are derived from the enterically transmitted non-A/non-B viral hepatitis agent, known as hepatitis E virus (HEV). The HEV antigens and in particular, a soluble 62 kDa species of the capsid protein encoded by ORF2, are immunoreactive with sera from individuals infected with HEV. The 62K antigen may be produced by a baculovirus expression vector and forms virus-like particles (VLPs). The antigens are useful as diagnostic reagents in diagnostic methods and kits for determining infection of an individual with HEV. The antigens are also useful in vaccine compositions effective in methods for preventing HEV infection.
