  • Patent number: 10493197
    Abstract: A blood treatment apparatus comprising: a blood treatment unit; a blood line configured to extract blood from a blood source, pass the blood through the blood treatment unit and deliver treated blood to a target vessel; and a fluid line configured to pass treatment fluid through the blood treatment unit and deliver used treatment fluid to a fluid sink. A flow divider is arranged in the fluid line that separates treatment fluid into a first fluid section and a second fluid section, thereby electrically isolating the fluid sections such that electrical current flowing in the fluid line between the fluid sections is limited. Related manufacturing and verification methods are also described.

  • Publication number: 20190364288
    Abstract: A processing for a first pixel in a picture comprises setting upper and/or lower limits of a first color component of the first pixel in a first color space to a respective fixed value if a maximum and/or minimum value of the first color component in the first color space results in a color component in a second color space that is below a first value of the color component in the second color space and above a second value of the color component in the second color space. A filtered value is obtained of the first color component and which is equal to or larger than the lower limit and equal to or lower than the upper limit. The processing results in filtered values that are cheaper to encode but that are visibly undistinguishable from the original colors of the pixels.

  • Publication number: 20190349606
    Abstract: A deblocking filtering control involves deciding whether to apply deblocking filtering to sample values in a sample block in a picture and in a neighboring sample block in the picture based on i) a first magnitude modification of sample prediction values in a first prediction block in a reference picture for the sample block and ii) a second magnitude modification of sample prediction values in a second prediction block in the reference picture for the neighboring sample block. The sample block and the neighboring sample block are separated in the picture by a block boundary. This decision to apply deblocking filtering based on magnitude modifications reduce blocking artefacts that may otherwise arise in certain pictures of a video sequence.

  • Publication number: 20190288861
    Abstract: Computing devices and method for performing a secure neighbor discovery. A local computing device transmits an encrypted local node identifier and an encrypted local challenge to a remote computing device. The remote computing device generates a local challenge response based on the local challenge; and transmits an encrypted remote node identifier and an encrypted local challenge response to the local computing device. The local computing device determines that the received local challenge response corresponds to an expected local challenge response generated based on the local challenge. The remote computing device further transmits an encrypted remote challenge. The local computing device generates a remote challenge response based on the remote challenge; and transmits an encrypted remote challenge response to the remote computing device.

  • Publication number: 20190280922
    Abstract: Computing device (located in a fabric of a data center) and method for generating a link IPv6 address. The computing device determines a local node identifier and a local link identifier for a communication interface of the computing device. The computing device receives from a remote computing device a remote node identifier and a remote link identifier for a remote communication interface of the remote computing device. Based on a comparison of the local and remote node identifiers, the link IPv6 address is generated by using an IPv6 base prefix, the local node identifier, the remote node identifier, the local link identifier, the remote link identifier, and an indicator that the local node identifier is greater or lower than the remote node identifier. A network configuration of the computing device is performed by generating a fabric-wide IPv6 address and one or more link IPv6 address.

  • Publication number: 20190246123
    Abstract: A processing for a first pixel in a picture comprises obtaining a lower limit of a first color component of the first pixel in a first color space based on a distance between a color of the first pixel and a first distorted version of the color in a second color space. An upper limit of the first color component in the first color 5 space is obtained based on a distance between the color and a second distorted version of the color in the second color space. A filtered value is obtained of the first color component and which is equal to or larger than the lower limit and equal to or lower than the upper limit. The processing results in filtered values that are cheaper to encode but that are visibly undistinguishable from the original colors of the pixels.
