    摘要： A closed loop three color alignment system for a digital projector comprises a light source and an optical engine (50) which splits a beam of light from the light source into first, second, and third wavelength bands. A first, second, and third spatial light modulator (11, 12, 16) imparts image data and a first, second, and third fiducial data to the first, second, and third wavelength bands. A combiner combines the modulated first, second, and third wavelength bands. A diverter diverts a portion of the combined modulated wavelength bands to a sensor. The sensor (21) senses a relative position of each of the fiducials and sends the position information to a microprocessor. The microprocessor then determines an error based on the relative position of the fiducials. The microprocessor then sends a signal to at least one component of the system to resolve the error.

    摘要： A keyed data-and-print album page has a receiver having an array of image spaces, a plurality of invisible printed encodements, and a visible key. The image spaces each have a visible boundary. The encodements each have a margin. The encodements each at least partially overlap at least one of the image spaces. The margins are each in registration with at least one of the boundaries. The key indicates the relative geometry of the boundaries of the visible image spaces and the margins of the invisible encodements.

    摘要： An intermediate storage unit for use with electronic film of the type having a body in the shape of a film cartridge and a tab, extending from the body and bearing an image sensor adapted to be located in the film plane of a conventional photographic camera and having electrical contacts for interfacing the electronic film with another electronic device, such as a computer. The intermediate storage unit includes a data connector for connecting to the electrical contacts on the tab of the electronic film and a communication interface connected to the data connector. A non-volatile semiconductor memory capable of storing at least twice as many images as the electronic film is provided in the storage unit. A microcontroller connected to communication interface and the non-volatile memory controls the transfer of data from the electronic film to the non-volatile memory.

    摘要： A line leak test probe for use on a liquid conduit. A pressure transducer is mounted in mechanical contact with the liquid in the conduit and a temperature transducer is mounted in thermal contact with the liquid. The transducers provide signals to a microprocessor-based circuit which includes a timer. Software stored in the microprocessor analyzes the time rate of change of the pressure to determine if there is a leak. Normally a sequence of three tests are performed: a catastrophic test, a gross test, and a precision test. The catastrophic test exits to the gross test if the rate of change of the pressure is less than a first rate, and the gross test exits to the precision test if the rate of change is less than a second rate which is less than the first rate. The precision test normally cycles until the pressure drops below 4 psi, and then outputs a leak signal if the pressure drops to below 3 psi in 12 minutes or less. If the temperature change during the test is sufficient to account for the pressure change, or the temperature is out of a range where it can be measured, the test aborts without outputting a leak signal.
