Abstract: The vehicle monitoring system includes a plurality of cameras provided corresponding to a plurality of doors provided on both sides (A side and B side) of each vehicle, and a management device for determining a camera corresponding to an open door. The management device determines a camera whose initial position is on the B side as the display use camera to be used for display, with respect to a vehicle in which the initial position of the door open camera corresponding to the open door identified by the open door identification information, and the door opening-side information match with the B side. With respect to a vehicle in which the initial position of the door open camera and the door opening-side information do not match with the B side, the management device determines a camera whose initial position is on the A side as the display use camera.

Abstract: An object of the present invention is to provide a threaded connection that has a wide range of torque at which a predetermined performance is achieved. The threaded connection according to the present invention includes a pin (1) including a wedge male thread (11) having a varying-thread-width portion (11A) and a box (3) including a wedge female thread (31) having a varying-thread-width portion (11A). The threaded connection is constructed such that, when both stab flanks (111) and load flanks (112) of the male thread (11) of the pin (1) contact the box (3), the shoulder (12) on the pin (1) is not in contact with the shoulder (22) on the pin (2), and, with a further rotation in the make-up direction, the shoulder (12) on the pin (1) is capable of contacting the shoulder (22) on the pin (2) before the threads (i.e. male and female threads (11) and (31)) yield.

Abstract: An image processing device or a method of processing an image is disclosed. The method includes receiving an image, detecting a plurality of person images in the image, identifying at least a first person image from among the plurality of person images by a preferential method, identifying at least a second person image from among the plurality of person images excluding the first person image, by an exhaustive method, and extracting a first feature amount as to the first person image and a second feature amount as to the second person image during a time interval. For example, the total number of the first person images and the second person images is no more than a maximum number of person images, identified by performance corresponding to process the person images during the time interval.

Abstract: A technique useful for searching which part of a predetermined area a person who has not yet reached a target position in the predetermined area until a scheduled time, is located. A boarding passenger management device and a boarding passenger reception terminal obtain a boarding passenger management number of the person who enters a boarding lobby, a monitoring camera captures an image of the person, monitoring cameras installed in association with multiple division areas capture an image of each of the division areas. The boarding passenger management device identifies the person who has not yet reached the boarding gate even though it is after the scheduled time, and the boarding passenger management device and the face feature quantity search device identify a division area where an image of the person considered to be a not-yet arrived target person is captured.

Abstract: A technique useful for searching which part of a predetermined area a person who has not yet reached a target position in the predetermined area until a scheduled time, is located.

Abstract: When an internal terminal (TM1 to TMn) replaced with another terminal due to the breakdown or the model upgrading and the DHCP function allocates a new private address for the MAC address of the terminal after replacement, the newly allocated private address is managed in association with physical ports (PP1 to PPn) in an expansion NAPT table. Then, in this state, when an IP packet is delivered from an external terminal (TM0) on the side of a WAN(2), the transmission destination address of this IP packet is converted to the private address of the internal terminal after conversion in accordance with the expansion NAPT table using the physical ports as a key.

Abstract: A network management system which can easily rebuild the system even when a switch in the configuration of cars occurs. A monitor apparatus including monitor cameras (1-1˜1-4, . . . ) and recording devices (1-5, . . . ) in each car (21a, 21b, . . . ) is networked. Each intra-car network is constructed as a LAN, a router (1-10 (RT1), . . . ) is connected to the LAN in each car, and an inter-car network is constructed as a WAN. The same apparatus in each car and apparatuses provided at the same positions are connected to a port of the same port number and the same LAN address is allocated to such an apparatus. As for an access from a WAN side, which apparatus is accessed is defined only by a difference in port number. Network information of the car switched car can be set merely by switching the setting of the WAN address of the router, . . . .
