  • Patent number: 11930995
    Abstract: A method for obtaining and processing image data by using a medical visual aid system including a monitor and an endoscope configured to be inserted into a body cavity and including an image capturing device and a light emitting device, the method including illuminating a field of view of the image capturing device with the light emitting device, capturing the image data using the image capturing device, providing a non-linear scaling model adapted to the body cavity, adjusting the image data by applying the non-linear scaling model such that adjusted image data is formed, and presenting the adjusted image data on the monitor.

  • Publication number: 20170009396
    Abstract: The present application provides a type of fabric with a surface cooling function and a preparation method therefor. The preparation method comprises the following steps: S1. using a surface cooling material to generate a polymer-modified surface cooling material by in-situ polymerization; S2. dispersing the polymer-modified surface cooling material in a finishing solvent to obtain a functionalized fabric finishing solution; and S3. absorbing the functionalized fabric finishing solution into the fabric and then finishing the fabric with the polymer-modified surface cooling material by thermal treatment, so as to obtain the fabric with the surface cooling function. The fabric with the surface cooling function in the present application feels good and is breathable. The solution of the preparation method for the fabric with the surface cooling function in the present application is simple and feasible and applicable to large-scale production.

  • Patent number: 8769665
    Abstract: Methods, systems, and apparatuses are described for implementations of an Internet protocol (IP) communication device (e.g., an IP phone) that contains a firewall. The IP communication device is coupled between a computer system and a network. A data packet is received at a first port of the IP communication device. The data packet is filtered with the firewall included in the IP communication device. The filtered data packet may be transmitted from a second port of the IP communication device (in modified or unmodified form), or may be canceled based on the filtering. In one implementation, the first port is coupled to the network and the second port is coupled to the computer system. In another implementation, the first port is coupled to the computer system and the second port is coupled to the network.
