A control system for a marine vessel having one or more engines and a transmission associated with each engine is disclosed. The control system includes one or more control stations, each having a control arm and arm position means coupled to the control arm for providing an electrical signal that represents a position of the control arm within its operating range. The system includes one or more electronic control units, each of which is electro-mechanically coupled to an engine and a transmission. A first electronic control unit (ECU) includes input means for receiving the electrical signal, control means for controlling a throttle of a first engine and shift position of a first transmission based on the electrical signal, and output means for providing a control signal that represents a current position of the control arm to a second ECU. The second ECU is coupled to the first ECU via the communications link, and includes input means for receiving the control signal from the first ECU, and control means for controlling the throttle of a second engine and the shift position of a second transmission based on the power train control signal.

Electronic control system for marine vessels

A multipoint, multiple function recorder which can record, display, and process up to 135 input/output data points, either analog or discrete, in various combinations. A strip chart recorder is provided for permanently recording input and output data points and, in conjunction with the chart recorder, a separate programmable dot matrix display is provided, such display being responsive to the same input/output data points and operable for displaying data in both alphanumeric and graphic form, the display being independently operable from said chart recorder, such that said input/output points are displayable at different times from the times when they are being printed on the chart recorder.

Programmable electronic display for a chart recorder

An improvement is provided for printer such as the dot matrix or thermal type, in which the printhead is stepped across the paper over a multicolor ribbon supplied from a pivotally mounted cartridge and transported through a plane between the line of traverse of the printhead and the surface of the paper. The ribbon is guided by guiding surfaces positioned on each side of the printhead, close to the printhead, and mounted to move with the printhead across the paper so that the guide surfaces will guide the path the ribbon takes to one which passes between the printhead and the paper with the guide being moveable in steps in a direction normal to the traverse of the printhead and parallel to the plane of the ribbon so as to position a selected color band of the ribbon under the printhead to select the color to be printed as the printhead traverses the paper. The ribbon cartridge is free to pivot in response to movement of the ribbon guide and/or the printhead so as to accommodate the different positions of the ribbon with respect to the printhead, as determined by the ribbon guide and the different positions of the printhead with respect to the paper.

Color change system for multicolor strip chart recorders

A multipoint recorder with a slow effective chart speed is operated to provide good visibility for the most recent record. A number of consecutive values for each point are scanned and stored. These values are recorded by a high speed printing mechanism during a first period of the recording cycle after which the chart is advanced forward for the remaining period of the recording cycle to a point which makes that record easily visible. At the end of the recording cycle the chart is retracted to start the next printing period with the printing mechanism at a point which corresponds to that required make the record look like a continuous line and to provide the desired time scale along the chart. To accomplish this the cycle time is coordinated to the chart speed and the number of consecutive scans recorded during each recording cycle.
