Abstract: A radio communication apparatus includes: control circuitry, which, in operation, selects, as a radio channel used for transmission, at least one radio channel among a plurality of radio channels based on information on a reduction time of a sum of transmission time per unit time in each of the plurality of radio channels; and radio circuitry, which, in operation, performs transmission using the selected radio channel.

Abstract: A mobile radio apparatus transmits to a plurality of fixed radio apparatuses, a fingerprint that indicates a reception strength distribution of radio signals from the plurality of fixed radio apparatuses. Each of the plurality of fixed radio apparatuses in which a learning model is installed inputs the fingerprint to the learning model and transmits a degree of proximity of the mobile radio apparatus output from the learning model to another one or more of the plurality of fixed radio apparatuses, and determines a position of the mobile radio apparatus, based on a first degree of proximity output from the learning model and a second degree of proximity received from the other one or more of the plurality of fixed radio apparatuses.

Abstract: A radio communication apparatus in a wireless mesh network includes reception circuitry, which, in operation, receives a radio signal; and control circuitry, which, in operation, determines a candidate radio device that is not selected as a forwarding destination of the received radio signal, based on destination information of the received radio signal and information on a group to which another candidate radio device capable of communication belongs.

Abstract: This waveguide comprises: three or more conductor layers that are stacked; two or more dielectric layers that are stacked, each being formed between two conductor layers adjacent to each other among the three or more conductor layers; and a first via group and a second via group each including one or more vias disposed in at least one dielectric layer among the two or more dielectric layers. The first via group and the second via group are arrayed in parallel. Among the vias included in the first via group and the second via group, the vias disposed in at least one of the two or more dielectric layers differ in position on the plane of the dielectric layer from the vias disposed in the remaining dielectric layer.

Abstract: In a radio network system containing a first radio apparatus that performs central control and a second radio apparatus, the second radio apparatus receives a first signal containing first identification information indicating a transmission source during a first reception period, receives a second signal containing second identification information indicating a transmission source during a second reception period, measures first reception information on reception of the first signal, measures second reception information on reception of the second signal, and transmits first measurement information containing the first reception information and the first identification information and second measurement information containing the second reception information and the second identification information to the first radio apparatus. When the first identification information and the second identification information are the same, the first radio apparatus compares the first reception information and the second reception information to determine whether a radio apparatus in an abnormal condition is present.

Abstract: A radio communication apparatus includes reception circuitry, which, in operation, receives a first frame transmitted by a first node in a wireless mesh network; and control circuitry, which, in operation, configures a relay destination node as second information in case that the first frame includes first information indicating a third node that performs transmission in cooperation with a second node that transmits a radio signal to a radio link in which communication quality is less than a threshold in the wireless mesh network and in case that the third node included in the first information indicates the radio communication apparatus, the relay destination node being a node to which the second node transmits the first frame, the second information indicating a relay destination node to which the third node transmits the first frame.

Abstract: This waveguide comprises: a first multilayered board in which a first dielectric layer and a plurality of first conductive layers the latter of which has a first opening are stacked; a first through via group in which a plurality of first through vias for electrically connecting the first conductive layers are aligned, in an in-plane direction of the first multilayered board, at intervals that are equal to or less than the one-half wavelength of an electromagnetic wave that is to be caused to propagate through the waveguide; and a second through via group in which a plurality of second through vias for electrically connecting the first conductive layers are aligned at said intervals in the in-plane direction. The waveguide does not have any through vias other than the plurality of first through vias and the plurality of second through vias. The first through via group and the second through via group are arranged, in the in-plane direction, in a direction orthogonal to the direction of the electric field of signals propagating in the thickness direction of the first multilayered board and are opposed to each other with the first opening therebetween.

Abstract: This sensor includes: a sensing circuit for detecting an object moving along a path; a receiving circuit for receiving, from other sensors that have detected the object, identification information for the other sensors; and a control circuit for causing a storage circuit to store the most recently received identification information for another sensor in response to the detection of the object by the sensing circuit.

Abstract: An information processing apparatus for associating an identifier of each of a plurality of sensors and a known installation position of a corresponding one of the plurality of sensors receives an identifier transmitted by a detection-complete sensor that has detected an object; associates, in a first path that is a part of the path, the identifier with an installation position of the detection-complete sensor in a reception order of a plurality of the identifiers; receives, from a detection-incomplete sensor that has not detected the object, reception strength information including an identifier of the detection-incomplete sensor and a reception strength of a signal of another one or more of the plurality of sensors in the detection-incomplete sensor; and associates, for the detection-incomplete sensor installed on a second path that is a rest of the path, the identifier of the detection-incomplete sensor and an installation position of the detection-incomplete sensor.

Abstract: An object detection apparatus in a vehicle is provided. The object detection apparatus includes one or more sensors configured to detect at least one object located on at least three rows of seats in the vehicle, the one or more sensors being positioned on a ceiling of the vehicle. The object detection apparatus further includes a circuit configured to determine whether or not the at least one object detected is a living-object. A number of the one or more sensors is less than a number of the at least three rows of seats.
