Abstract:
A color measurement instrument (10) wherein the communication protocol used by the instrument is determined by the cable (14) attached to the instrument. The instrument (10) includes a handheld unit (12) having a control system (20) capable of communicating in at least two different protocols through a common connector (40). This control system connector (40) includes a set of pin-outs corresponding to each of the available protocols. The instrument also includes a cable (14) having a connector (50) mated with the control system connector (40). The pin-out of the cable connector (50) corresponds to only one of the sets of pin-outs of the control system connector (40), so that the cable (14) provides a communication pathway corresponding to only one of the available protocols.
Abstract:
A densitometer apparatus (410) is disclosed and is adapted to provide color density measurements of object samples. The densitometer apparatus (410) comprises a source light (580) for projecting light toward an object sample comprising a control strip (588, 620). A reflection optics assembly (576) is adapted to measure light density reflected from the object sample when the object sample is in the form of a paper control strip. A transmission optics assembly (618) is adapted to measure transmission density of light rays projected through the object sample when the object sample is in the form of a film control strip. A motor assembly (426) operating with a drive wheel assembly (434) and idler wheel assembly (440) automatically moves the object sample (588, 620) through the apparatus (410) adjacent the source light (580). A pair of guides (468, 470) are selectively adjustable by the operator to control movement of the object sample (588, 620) through the apparatus (410). In response to input from a key switch assembly (492) activatable by the operator, the apparatus (410) is adapted to perform various color density measurement and calibration functions, and display appropriate information to the operator through the use of a visual display (490).
Abstract:
A color measurement network message log structure (800) is disclosed for use in controlling communications among systems such as a plurality of film processing laboratories (802) and remotely located systems, including a remotely located host system (850). Each processing laboratory (802) includes at least one film processing apparatus (804) interconnected to a densitometer (210) for obtaining data related to color quality during film processing procedures. The densitometer (210) includes a network message structure for queueing data for subsequent transmission. The remotely located system (850) is capable of direct control of the film processing apparatus (804) through the use of a pass-through mode associated with a dual port structure (A, B) of the densitometer (210).
