摘要:
The present invention is directed to a method and apparatus which utilizes a software-based digital signal processing circuit to generate a signal which is representative of the status of a movable component. A preferred embodiment of the apparatus of the present invention includes a synchro which is connected to a movable component. An analog reference excitation may be applied to the synchro, and the synchro generates analog synchro signals which bear a relationship to the status of the movable component. The analog synchro signals are converted to digital synchro signals by a plurality of analog-to-digital converters. A digital reference signal and the digital synchro signals are provided to a software-based digital signal processing circuit which preferably corrects constant and time-varying errors in the digital synchro signals and generates a status signal which is representative of the status of the movable component. For instance, the status signal may represent the angular position of the movable component. A different embodiment of the status signal may represent the angular velocity of the movable component.
摘要:
An apparatus and method is provided for capturing component location information through the use of fiber optic conduits. In various embodiments, an image of a component attached to a translatable and rotatable spindle (302) is captured and transmitted along a fiber optic conduit (305) to a camera (316) coupled to an image processing computer (318). The image processing computer (318) determines component location on the spindle based on the transmitted image and, where necessary, generates component location correction information so that the spindle and attached component can be moved to a determined location. A plurality of fiber optic conduits (305, 308, 311, 314) may be bundled together to provide a single combined image of the components (A1, A2, A3, A4) attached to multiple spindles which can be captured by a single camera (316), wherein the image processing computer (318) segregates the images and determines multiple component location correction information.
