  • Publication number: 20210206800
    Abstract: The present invention provides improved processes for purifying semaglutide or liraglutide. Semaglutide or liraglutide is purified via two sequential RP-HPLC purifications followed by a salt-exchange step, where a pH is kept constant in the first and second purification steps. In particular, the processes utilize a halogenated solvent in a sample preparation step, which provides better solubility and an environment suitable for decarboxylation for crude semaglutide or liraglutide prior to a RP-HPLC purification.

  • Patent number: 9609378
    Abstract: An IP camera, a communication method and a communication system are provided. The IP camera includes an image capturing unit, a video processing unit and a connection processing unit. The image capturing unit captures a plurality of consecutive images. The video processing unit is coupled to the image capturing unit, and generates a first video stream and a second video stream according to the images. The connection processing unit is coupled to the video processing unit, processes the first video stream into a first packet stream, and processes the second video stream into a second packet stream. The connection processing unit transmits the first packet stream to a local area wireless network unit through a first wireless link, and the connection processing unit transmits the second packet stream to an external electronic device through a second wireless link.

  • Patent number: 9244505
    Abstract: A portable electronic device with an exposed heat dissipating mechanism includes a housing and a heat dissipating plate. A heat generating unit is arranged inside the housing, and the heat dissipating plate includes a main body arranged inside the housing and at least one cooling portion extended from the main body and exposed on the housing. The main body and the heat generating unit are thermally connected to each other. Therefore, the effectiveness of the heat dissipation can be enhanced without increasing the thickness of the device and such that the need for heat dissipation in a portable electronic device of higher performance and computing power can be satisfied.
