  • Patent number: 11606825
    Abstract: A RAN node (2) receives, from a core network node (6, 7, 8), a first identifier that is used by a service, an application, or an edge server (5) to identify a radio terminal (1) connected to the RAN node (2), and associates the first identifier with a second identifier that is used by the RAN node (2) to identify the radio terminal (1). Further, the RAN node (2) communicates with the edge server (5) using the first identifier. It is thus, for example, possible to allow an MEC server (or an MEC application hosted on the MEC server) and a radio access network (RAN) node to directly exchange therebetween a control message regarding a specific radio terminal.

  • Patent number: 11587769
    Abstract: A device includes a microwave generator configured to generate a microwave having a bandwidth, an output unit, a directional coupler and a measurer. The microwave generator generates a microwave a power of which is pulse-modulated to be a High level and a Low level. A set carrier pitch is set to satisfy a preset condition. The preset condition includes a condition that a value obtained by dividing a set pulse frequency by the set carrier pitch or a value obtained by dividing the set carrier pitch by the set pulse frequency is not an integer and a condition that an ON-time of the High level is equal to or larger than 50%. The microwave generator averages a first High measurement value and a first Low measurement value in a preset moving average time longer than a sum of the ON-time of the High level at a preset sampling interval.

  • Publication number: 20220245979
    Abstract: A passage propriety assessment device, provided with: a assessment unit that authorizes a person to pass through a first entrance/exit when a first facial image of the person at the first entrance/exit satisfies an individual authorization criterion, which is a criterion for assessing by facial recognition that the person is a pass-authorized person; and a setting unit that, when it is assessed that a person who has been authorized to pass through the first entrance/exit is impersonating a pass-authorized person, sets the individual authorization criterion for a pass-authorized person for a second entrance/exit located after the first entrance/exit so as to be higher than the individual authorization criterion for the first entrance/exit. When a second facial image of a person at the second entrance/exit does not satisfy the individual authorization criterion that was set higher, the assessment unit restricts the person from passing through the second entrance/exit.

  • Patent number: 10614940
    Abstract: A superconducting magnet device with which device breakage caused by a quench can be avoided while helium consumption is reduced. A sheet-like convection-preventing member is disposed at least either above or below a heat transfer member transferring to gaseous helium heat transferred from the outside, so as to cover a helium gas release tube for the gaseous helium, and thus heat exchange performance during transportation is improved. In the case where the quench occurs, the convection-preventing member is lifted upward in the release tube, thereby ensuring to provide a flow path for the gaseous helium and avoiding excessive increase of the internal pressure.
