Abstract: A computer system and method of performing service thereto includes a centralized system status panel to identify and display the status of all field replaceable units (FRUs) within the computer system. The system uses electronic signaling such as LEDs on the system status panel to identify the presence and state of the FRUs within the system. The system further may use color differentiation to identify specific FRUs within the system. The system status panel may also include spatial locators to determine the location of the field replaceable units. Acronyms or symbols for the FRUs may further be included on the system status panel. Additionally, the computer system uses color differentiation on user accessible components and their interface features. Color differentiation on the user interface areas may allow a service technician to quickly identify where on the enclosures or individual component handling is possible or desirable. In addition, the computer system may use captive fasteners for the FRUs.

Abstract: Apparatus for inspecting sheet material having known characteristics is disclosed. The apparatus comprises means for providing a plurality of pixel signals each having a magnitude representing the intensity of electromagnetic radiation received from a corresponding point on the sheet material. The apparatus also comprises signal processing means for comparing the magnitude of each one of the pixel signals to a corresponding reference range defined by the known characteristics of the sheet material and generating a characteristic signal. The characteristic signal includes an event signal for each of the magnitudes falling outside of the corresponding reference range and a data signal for each of the magnitudes falling within the range, wherein the data signal represents the magnitude of the pixel signal. The signal processing means also generates an address signal representing the point on the sheet material at which the characteristic signal is generated.

Abstract: A golf ball dredge which comprises a shallow draft, buoyant support vessel in the form of a pontoon boat that provides a floating platform from which the dredging apparatus is supported. The pontoon boat has a small outboard motor mounted at its bow for providing a means for propulsion and steering of the boat. A relatively high pressure, gasoline powered, centrifugal water pump is mounted on the pontoon boat with its suction intake located below the water level. The pump provides a high pressure water outlet discharge that is supplied through eductor tubes into the inlet end of a bottom suction intake piping system. The bottom suction intake piping system also is supported on the pontoon boat with its inlet end submerged below the surface of the water to a suitable depth for lightly contacting the bottom of the waterhole.
