  • Publication number: 20180176190
    Abstract: A sender device includes a non-transitory memory storage comprising instructions and a location control policy, and a processor coupled to the memory. The processor executes the instructions to generate an email, generate a control mechanism for the email, wherein the control mechanism instructs a security server to implement the location control policy and wherein the location control policy affects a recipient device's use of the email, and integrate the control mechanism into the email to generate an integrated email. The sender device further includes a transmitter coupled to the processor and configured to transmit the integrated email to the security server for the security server to implement the control mechanism.

  • Patent number: 9708389
    Abstract: The invention relates to a method for preparing a homodimer protein mixture by using repulsive interaction of charges. The method comprises the step of replacing part of residues with the opposite-charged residues, so that different proteins or antibodies are unfavorable to forming heterodimers due to the repulsive interaction between like charges, while same proteins or antibodies are favorable to forming homodimers due to attractive interaction between opposite charges. The homodimer protein mixture obtained according to the method of the invention can simultaneously act on different epitopes of the same target, and simultaneously inhibit the effects of a plurality of antigens by binding to the antigens from different sources, thereby providing a new approach towards immunological diagnosis and treatment of tumors and other diseases.

  • Publication number: 20170084032
    Abstract: An image processing method for a unmanned aerial vehicle includes: aligning a subject matter by a camera of the unmanned aerial vehicle focusing on the subject matter at A first time, and recording images information in a focus flame as first reference pattern, presetting a separation distance of automatic movement of the unmanned aerial Vehicle, focusing on the subject matter at a second time, and recording image information in the focus frame as a second reference pattern, synthesizing a three-dimensional reference pattern of the subject matter according to the first reference pattern and the second reference pattern, automatically traversing images in whole camera aperture by the focus frame when the unmanned aerial vehicle detects interrupt of controlling signal, and comparing with the three-dimensional reference pattern.

  • Publication number: 20170003051
    Abstract: This invention discloses a controlling method of instant water heater having multiple heating tanks parallel with each other. The branches of the heating tanks are all set with valve unit that controls on/off of the heating tank's water inlet terminal except for one branch; the control method are: setting two flow comparison value, L1 and L2 respectively; if current tested flow rate is higher than L2, then gradually turn on branches' valve unit; if current tested flow rate is lower than L1, then gradually turn off branches' valve unit; current heating tanks separately control heating power change based on current flow rate and temperature, and heat the water in it to preset temperature, one of these heating tanks will feedback according to mixed temperature, then feedback to slightly adjust temperature control, so water heater's outlet temperature reaches set temperature completely.
