Abstract: In one embodiment, an angular distance calculation technique may enable an intermediate node, such as a route reflector, to render customized best path selection decisions to destination address prefixes and advertise those decisions to its intermediate peering nodes, i.e., route reflector clients, in an autonomous system of a computer network. That is, the route reflector may execute a routing protocol, such as BGP, to select and advertise a next hop (e.g., an address prefix of an egress point of the autonomous system) associated with a customized best path to a route reflector client based on an angular distance between the route reflector client and the egress point. In this manner, the route reflector client may route data traffic destined to a destination address prefix utilizing the egress point associated with the customized best path to that prefix.

A process for temperature equalization between an upper dome chamber above a support plate and a lower chamber below it is described. It is proposed that the cross section of the equalization opening be variable as a function of the temperature, so that the flow of medium between the upper dome chamber and the lower chamber is varied as a function of the temperature.

Abstract: The camera of this invention preferably includes a rewind interlock that prevents the double exposure of film. Preferably, the camera of this invention is an Advanced Photo System (APS) camera that employs APS film. Such APS film may be contained in a film cassette that has a light lock door. The rewind interlock prevents thrusting or pulling a frame of film from the film cassette after that frame of film has been exposed and rewound into the film cassette. This prevents the accidental double exposure of a frame of film. In a preferred embodiment of this invention, the rewind interlock prevents thrusting or pulling film from a film cassette after all of the film has been rewound into the film cassette. Preferably, the rewind interlock prevents the thrusting or removing of exposed film from a film cassette.

Abstract: A camera is used with a photo film cassette of a predetermined type. The photo film cassette includes a spool about which photo film is wound. A cassette shell contains the spool in a rotatable manner. A data disk with a bar code is disposed on the spool in a manner readable externally outside the cassette shell for signaling photo film information.

Abstract: A camera uses a film cartridge, which has an information recording disk which is rotatable integrally with a cartridge spool shaft and represents information inherent to a film, and feeds the film leading end portion from the cartridge by using a driver. A data detector reads the film information from the disk of the cartridge loaded in the camera. A nonvolatile memory stores the film information read from the disk. When the cartridge is loaded into the camera, the camera feeds the film leading end portion from the cartridge, reads the film information, and writes the read information in the memory. Another camera uses a film having two perforations per frame. The moving amount of the film fed by a motor controller is detected by a film driven roller rotation detector. A perforation on the film is detected by the perforation detector. Prior to at least the driving operation of the motor controller, information indicating the film feeding operation is stored in an EEPROM.

Abstract: An electro-developing type camera uses an electro-developing recording medium, and has a determiner for determining whether the electro-developing recording medium has been recorded on or not when being loaded in the camera, and a selector for selecting one of a photographing mode and an image-reading mode as an operation mode of the camera. A photographing operation is executed in the photographing mode to record and develop an optical image in the electro-developing recording medium. An image-reading operation is executed in the image-reading mode to read the developed image of the electro-developing recording medium. The photographing mode is selected by the selector when the determiner determines that the electro-developing recording medium has not been recorded, and the image-reading mode is selected by the selector when the determiner determines that the electro-developing recording medium has been recorded.

Abstract: An apparatus using a film cartridge in a system that a leading portion of a film contained in a cartridge is thrust to be conveyed from the cartridge, wherein an indicator showing an exposure condition is reset to an original state when an initial loading, which is executed on a film cartridge loading in an apparatus, is not executed normally, and the film is rewound, thus, it indicates "unexposed" when a new film cartridge is loaded. While, when a winding up operation is not executed normally during a photographing, a film is rewound and an indicator showing an exposure condition, is set so as to indicate that the film is exposed. Thus, it prevents from causing a double exposure.

Abstract: This invention is applicable to a camera having a cartridge chamber into which a film cartridge is detachably insertable along its axis direction. The camera is equipped with a cartridge-load detection switch for outputting a load signal when the cartridge is loaded in the cartridge chamber, and outputting a non-load signal when the loaded cartridge is drawn out from the cartridge chamber by at least a predetermined amount. When the photographed cartridge is partially drawn out from the cartridge chamber and then reloaded into the cartridge chamber as it is, the output of the load signal is continued if the draw-out amount is below the predetermined amount, thereby preventing an erroneous judgment that a new cartridge is loaded into the cartridge chamber. Therefore, for example, the double exposure can be prevented.

Abstract: The film feed control apparatus performs frame feed operation in which a photographic film is fed in a specific direction when a given photographic frame of the photographic film is being set at a specific position, and the photographic film is stopped when a next photographic frame is set at the specific position. The film feed control apparatus is provided with a feed device that feeds the film, and a control device that controls the feed device in such a manner that, when an unfinished film, which includes exposed frames and unexposed frames, is loaded, stops the film if an unexposed frame is set at the specific position while the unfinished film is being fed in the specific direction, which is the same as the direction of film feed during the frame feed operation.

Abstract: A camera has a feeding motor by use of which photo film is fed. 24 groups of perforations are arranged along one edge of the photo film, and regularly at a distance L2 one group from another. Each of the perforation groups is associated with one frame, and includes two perforations arranged at a distance L1 therebetween. To control the photo film feeding, pulses are generated in synchronism with the photo film feeding. The perforations are detected through a sensor. The pulses are counted while the photo film is fed by the distance L1 or L2, and during a period started upon movement of a first one of the perforations past the sensor and finished upon detection of a second one of the perforations at the sensor. A counted number of the pulses is compared with a reference value upon finish of counting the pulses. If the counted number is equal to or more than the reference value, the feeding motor is decelerated.
