An image forming system includes a substrate transport unit, an image forming module, an event sensing module, a heartbeat generation module, a signal detection module, and a repositioning module. The substrate transport unit may transport substrate including at least one splice along a transport path. The image forming module may form an image on the substrate. The event sensing module may detect an event and provide an event signal along a signal path in response to the event. The heartbeat generation module may provide a heartbeat signal different than the event signal along the signal path. The signal detection module may determine a presence of the event signal and an absence of the heartbeat signal. The repositioning module may move the image forming module from a first position to a second position in response to a determination of the presence of the event signal.

Detection of an event signal and a heartbeat signal provided along a signal path

One embodiment of a display system includes a control module that controls a position of an adjustable neutral density filter based on a calculated filter setting and that controls modulation of a set of frame data by an image modulator based on a calculated gain setting, and an image analysis module that calculates a gain setting and a filter setting for the set of frame data and forwards the calculated gain setting and the filter setting to said control module.

Display system

One embodiment of a display system includes a control module that controls an adjustable aperture based on a calculated aperture setting and that applies a calculated gain setting to a set of frame data to define a modified set of frame data, an image analysis module that calculates a gain setting and an aperture setting for said set of frame data and forwards said calculated gain setting and said aperture setting to said control module, and a frame data buffer that stores said set of frame data during calculation by said image analysis module.

A projection system for both color and monochromatic displays includes a color wheel having filter portions of different colors and a clear portion; and a drive system configured to keep the color wheel moving while keeping a projection light beam shining through the clear portion of the color wheel.

A printer having a power bus for delivery of power to a print carriage is disclosed. The power from the power bus is picked up by a charge pickup system mounted on the print carriage. The charge pickup system can include a conductor contact and a spring to pressure the conductor to maintain contact with the power bus. The power bus can be implemented on the slide bar or on a separate bus bar. A ground return bus can be used to provide ground lines to the print carriage.
