  • Patent number: 11546558
    Abstract: A method for displaying a video stream of a scene captured by a monitoring camera on a display of a remote client device comprises receiving, at the client device, the video stream and information indicating an on/off status for an IR-illuminator illuminating the scene; setting a display setting of the display differently based on upon the on/off status for the IR-illuminator; and displaying the video stream on the display using the display setting. The client device comprises a display, a receiver which receives a video stream from the monitoring camera, and a control circuit. The control circuit executes an IR-illuminator status function to extract information indicating on/off status for the IR-illuminator illuminating the scene, a display setting function of the display differently upon the on/off status for the IR-illuminator, and a displaying function displays the video stream on the display using the setting set by the display setting function.

  • Patent number: 8326387
    Abstract: A RE-type oxide superconducting wire having excellent angular dependence for magnetic field of Jc is obtained by finely dispersing magnetic flux pinning centers into a superconductor. A mixed solution which comprises a metal-organic complex solution including a metal element which composes a RE-type oxide superconductor whose Ba content is reduced and a metal-organic complex solution including at least one or more kinds of metals which are selected from Zr, Ce, Sn, or Ti which has a larger affinity for Ba is coated onto an intermediate layer of a composite substrate, and the assembly is then calcined to disperse artificially and finely oxide particles (magnetic flux pinning centers) including Zr. Thus, the angular dependence for magnetic field (Jc,min/Jc,max) of Jc can be remarkably improved.
