Abstract: A predictor 62 predicts a future of a prediction target in a traffic area. The predictor 62 includes a movement state information acquirer 620 configured to acquire movement state information, a surrounding state information acquirer 621 configured to acquire surrounding state information, a traffic environment information acquirer 622 configured to acquire traffic environment information, a driver state information acquirer 623 configured to acquire driver state information, a traffic scene specifier 624 configured to specify a traffic scene on the basis of the movement state information, the surrounding state information, and the traffic environment information, an action pattern selector 625 configured to select, as a predicted action pattern, at least one from among a plurality of predetermined action patterns on the basis of the traffic scene and the driver state information, and an action predictor 626 configured to predict future action on the basis of the predicted action pattern.

Abstract: A verification method for verifying an asynchronous circuit includes producing a netlist based on circuit information at a register transfer level, extracting delay information and an asynchronous circuit section in which circuits operating with different clock signals are coupled to each other from the netlist, processing the delay information to extend a malfunction generating period in the asynchronous circuit section, and executing verification of the asynchronous circuit based on the delay information having been processed.

Abstract: A device for switching over hub units is connected to a first hub unit or a second hub unit in an electrically interchangeable manner on one hand, and connectable to a plurality of terminal apparatuses on the other hand. The device and the first and second hub units, respectively, include an equal number of device ports, first hub ports and second hub ports for receiving or emitting data signals. The device further includes a unit-conversion switch. The device ports each contain a first connector connected to a first hub port via a first cable, a second connector connected to a second hub port via a second cable, and a third connector being connectable to a terminal apparatus via a third cable, respectively. The device ports further contain switching elements for connecting the third connectors either to the first connectors or to the second connectors.

Abstract: In an optical cable, at least one optical fiber is enclosed in a cover. The cover has an outer surface which in cross-section is in the shape of a trapezium formed by removing the right-angled isosceles corner region from a right-angled isosceles triangle. The optical cable can be installed running along a corner with its two perpendicular side faces lying against the surfaces which define the corner. Alternatively, the cable can be installed on a flat surface with the wider of the mutually parallel faces lying against the flat surface.

Abstract: In the floor-wiring structure for wiring a cable, a space is secured for storing a surplus part of the cable. Cable-cutting work and end portion conditioning on the working site are thus dispensed with and the surplus part of the cable is easily stored. The structure comprises unitary floor members having a pathway channel. Some of the unitary floor members are replaced by a floor member for storing part of the cable. The latter floor member comprises an upwardly opened space for storing part of the cable, entrance-and-exit ports thereto or therefrom, a guide provided in the space for storing cable for maintaining the cable in a looped state and a cable-fixing band provided in the same space for fixing the cable in a freely removable way.
