    摘要： A magnetic head is mounted on a camera film platen which is supported for constrained movement relative to the camera body to maintain a precise relationship between an information track recorded on the film and a film edge. The magnetic head is pivotally mounted on the film platen. Means are provided to establish one angular orientation of the head to establish one angular orientation of the head with respect to the film during prewind to read information recorded by the film manufacturer and a second different angular orientation during transport of the film in the opposite direction during film exposure to record information relating to film exposure. This enables a camera to distinguish between information recorded by the manufacturer and information recorded by a camera to determine if mid-roll interrupt occurred and, if so, the location of the last frame exposed.

    摘要： A magnetic head is mounted directly on a camera film platen which is supported for limited constrained movement to maintain a precise relationship between an information track and a film edge. The platen serves to maintain film flatness while providing the desired relationship between the magnetic head and film edge.

    摘要： A film cassette comprises a film spool supported within a lighttight shell for rotation in an unwinding direction to thrust a filmstrip coiled about the spool to the exterior of the shell and for rotation in a winding direction to return the filmstrip to the interior of the shell. According to the invention, a locking device is connected to the spool and the shell for preventing rotation of the spool in the unwinding direction, and is enabled for such purpose in response to rotation of the spool in the winding direction. This prevents a photographer from reusing the cassette in a camera after the filmstrip is fully exposed. The locking device can be manually defeated to reuse the cassette in the camera when the filmstrip is only partly exposed.

    摘要： In a Distributed Database System (DDS), database management and transaction management are extended to a distributed environment among a plurality of local sites which each have transaction server, file server, and data storage facilities. The Materialization and Access Planning (MAP) method of a distributed query, update, or transaction is an important part of the processing of the query, update, or transaction. Materialization and access planning results in a strategy for processing a query, update, or transaction in the distributed database management system (DSDBMS). Materialization consists of selecting data copies used to process the query, update, or transaction. This step is necessary since data may be stored at more than one site (i.e., computer) on the network. Access planing consists of choosing the execution order of operations and the actual execution site of each operation. Three access planning methods are used: General (Response), General (Total) and Initial Feasible Solution (IFS). For a distributed query, General (Response) and General (Total) decrease the communication cost and increase the local processing costs as compared to the IFS.
