The objects of the invention are generally accomplished by a method of delaminating imaging materials comprising providing an imaging material comprising donor and receiver elements, heating said imaging material, applying opposed forces to said donor and receiver elements to separate said imaging material into donor and receiver elements, and accumulating the separated donor element. In a preferred method one or both of said opposed forces is vacuum and when the vacuum is released from said donor element, accumulating takes place by spooling after separation. The apparatus for delamination of imaging materials comprises means for applying heat and pressure to said imaging material, means to apply a separating force to at least one of said donor element and receiver element forming said imaging material and means to separate said donor element and said receiver element. In a preferred embodiment the apparatus further comprises means to spool said donor element and means to preheat said imaging material prior to applying said separating force.

A shutter release cable adapter for connection to a mechanical shutter release of a film camera is provided with a bi-stable magnetic device to selectively position an internal shutter release plunger to either a translation blocking or unblocking position depending on an operating condition of the image capture system of which the film camera is a part. The magnetic device includes an electromagnet responsive to a system condition signal to generate a reversible magnetic field and a permanent magnet interactive with the electromagnetic field to position a projection mounted on the internal plunger to the respective blocking or unblocking position as determined by the condition of the image capture system. In the absence of an electromagnetic field the permanent magnet retains its assumed position by attraction of the permanent magnet field to the armature poles of the electromagnet.

Camera shutter release cable adapter

A simultaneous image capture system including a film camera and an electronic image capture system includes a shutter release cable adapter with means for generating an output signal in response to initiation of a picture taking event. If the electronic image capture system is not ready to accept a new image, an imaging system controller responds to the adapter output signal to generate a warning indication to alert the photographer not to continue with the picture-taking event. The cable adapter is preferably a two position electromechanical device having an input responsive to the imaging system controller. When the electronic image capture system is not prepared to accept a new image, the controller sends a system busy signal to the adapter to cause the adapter to assume a blocking setting that physically blocks the cable release from initiating a picture taking event. When the image capature system is free, the system busy signal is removed causing the adapter to revert to an alternate position that physically allows the cable release to initiate the picture taking event.
