Abstract: This disclosure relates to remote control of dialysis machines. In certain aspects, a method includes receiving a request for a network connection from a dialysis machine and establishing the network connection with the dialysis machine. The method also includes receiving, from a client device, a request to access the dialysis machine, authorizing the client device to access the dialysis machine, receiving, from the dialysis machine, information pertaining to an operation of the dialysis machine, and providing, to the client device, the received information.

Abstract: A best available video stream is determined for each of multiple conference participants within a conference room including multiple cameras based on scores determined for video streams obtained from the cameras. The scores are determined based on representations of the conference participants within the video streams, for example, based on percentages of conference participant faces visible within the video streams, directions of conference participant faces relative to the cameras, directions of eye gaze of the conference participants relative to the cameras, and/or degrees to which conference participant faces are obscured within the video streams. The best available video streams are output for rendering within separate user interface tiles of conferencing software.

Abstract: A pair of spectacles has a frame and two lenses. The frame has a skeleton and a bridge formed between the skeleton and dividing the skeleton into two symmetrical members. Two first lugs are transversely formed in a distal end of the skull and adjacent to the bridge, and two second lugs are uprightly formed in a free end of the skull and opposed to the bridge. Two lenses are respectively mounted on the members and respectively have a first channel and a second channel defined in a periphery of the lenses. Two first tabs and two second tabs are respectively mounted on the lenses and the frame in turn, whereby the lenses are securely provided on the frame with easy assembly.
