Abstract:
In an on-board engine trim balance information system comprising a housing and electronic circuit assembly in said housing, said housing having a front face, and said electronic circuit assembly including signal processing means for receiving signals from one or more engines indicative of vibrations generated during operation of said one or more engines and for processing said signals to generate vibration data, the system comprising:an integral alphanumeric display, disposed on the front face of the housing and integrally formed therewith, the alphanumeric display having multiple lines and multiple characters per line, the display operable to present vibration data and other information;a computer including a memory and a processing unit, the computer being connected to receive and store the vibration data from the signal processing means, and also being connected to operate the display, the processing unit and memory connected to provide a computer program that implements a plurality of display modes for presenting the vibration data and engine balance information derived by the computer from the vibration data, the computer program providing for switching between the display modes, the computer program also providing a multilevel menu structure for presenting the vibration data and engine balance information; andan integral operator interface including a set of actuators, the actuators disposed integrally with the front face of the housing, and the actuators connected to the computer for permitting a user of the system to perform a sequence of interactions by operating the actuators on the face of the housing to switch the computer program between the display modes, and to also thereby operate the multilevel menu structure to review vibration data and engine balance solution information.
