  • Patent number: 10305793
    Abstract: A communication device conforming with plural communication standards and having a storage storing a plurality of virtual stacks each having an application program and communication program that implements a protocol stack for communication by the application program. An executor executes the virtual stacks, and a switching controller switches the virtual stacks to be executed by performing a first processing in which at least one part of at least one of the virtual stacks is read from storage and stored into a memory of, and executed by, the executor. Then, in accordance with free capacity in the memory, at least one part of at least one of the virtual stacks executed in the first processing is deleted from memory. In a second processing at least one part of at least one of the virtual stacks is read from the storage and stored into the memory of, and executed by, the executor.

  • Patent number: 4464037
    Abstract: A camera having alternately selectable shutter release priority and focus control priority modes of operation. In the shutter release priority mode, operation of an automatic focusing device is inhibited when the shutter is actuated, and the shutter may be released irrespective of whether the photographic image is in focus. In the focus control priority mode, the shutter cannot be released unless the image is in focus. When the camera is in the shutter release priority mode, photographs may be taken in rapid succession without regard for precise focusing.
