Abstract:
METHOD AND APPARATUS FOR RECORDING AND USING EXPOSURE DATA IN A PHOTOGRAPHIC SYSTEM A method of operating a photographic camera to provide exposure information in association with a latent image picture frame includes the step of automatically providing a nominal exposure for the picture frame. An operator-selected exposure is provided for the picture frame which differs from the nominal exposure by a known under- or over-exposure. The picture frame is exposed in accordance with the operator-selected exposure, and data is recorded in association with the picture frame indicating the difference between the nominal and operator-selected exposures. A method of operating a photographic printing system is provided, responsive to the recorded data, for marking a photographic print to indicate to an observer the under- or over-exposure of the negative. A method of operating a transparency processing system is provided wherein, responsive to the recorded data, the slide mount is marked with the under- or over-exposure.
Abstract:
An automated storage and retrieval system stores containers, typically- containing biological or chemical samples, at ultra-low temperatures, i.e., from about -50 -C to about -90 -C, preferably about -80 -C under normal operating conditions. Dry gas air flows are used to reduce moisture and the consequential frost within the freezer compartment. A custom insulated door is provided with an access module (22) and a tube picking compartment (30) as well as servo motors for controlling a robot (48) within the ultra-low temperature freezer compartment. The robot automatically places sample storage containers in stationary storage racks within the freezer compartment. Magnetic couplings (70, 72) are used to transmit mechanical power from outside of the freezer compartment to the robot inside of the freezer compartment. The robot has a simplified mechanical configuration. The custom door can be readily attached to standard freezer bodies.
Abstract:
METHOD AND APPARATUS FOR DETECTING, RECORDING AND USING SCENE INFORMATION IN A PHOTOGRAPHIC SYSTEM A method of operating a photographic camera to record data in correspondence with a picture frame includes activating a flash to provide illumination for exposing the picture frame onto a photographic film. Sensing is performed to determine if light generated by the flash is reflected from a subject in the picture frame. Data is recorded in association with the picture frame indicating if reflected light is sensed. In accordance with a method of operating a photographic printer to print a negative frame, the reflected flash illumination data associated with the negative frame is read. An appropriate exposure for the negative frame is selected based at least in part on the presence or absence of the sensed reflected flash illumination.

Camera Apparatus For Use With Film Cassette Having Locking Means For Exposure Status Indicator A photographic camera to be used with a film cassette having a locking member movable between respective locking and non-locking positions for arresting and releasing a film exposure status indicator in any one of several exposure status positions, is characterized in that a loading chamber is configured to receive the film cassette with the indicator in at least one of its exposure status positions and actuation means is located in the loading chamber for moving the locking member from its locking position to its non-locking position responsive to insertion of the cassette into the loading chamber and for moving the locking member from the non-locking position to the locking position responsive to removal of the cassette from the loading chamber.
Abstract:
FILM CASSETTE HAVING FILM-EXPOSED STATUS INDICATOR A film cassette is disclosed wherein a filmstrip is advanced to the outside of a lighttight cassette shell in order to expose successive imaging areas of the filmstrip and can be returned to the inside of the cassette shell before all of the imaging areas have been exposed or after the filmstrip has been substantially completely exposed. According to the invention, a filmexposure status indicator is supported on the cassette shell for movement relative to the shell from a normal first position to successive second and third positions for providing respective visible indications that the filmstrip is generally unexposed, the filmstrip has been returned to the inside of the shell before all of its imaging areas have been exposed, and the filmstrip is substantially completely exposed.
