  • Such components may be positioned such that they may be viewed by an operator looking at the outside of the housing 10 or they may be positioned within one or more of the cavities 18 formed in the housing 10.
  • the indicator lights 40 and the display panel 42 may be viewed from the outside, such as when the housing 10 is retrieved from downhole.
  • the indicator lights 40 and/or display panel 42 may be employed in a variety of different contexts.
  • a control logic may be established such that an indicator light is "on” only when a sensed parameter, e.g., temperature, pressure, torque, etc., exceeds a preselected allowable limit or range, i.e., the indicator light can indicate an out-of-tolerance or problem condition.
  • the control logic may be established such that the indicator light is always “on” and only goes off when an out-of-tolerance condition is sensed.
  • Colored indicator lights may also be employed with the present invention, e.g., red and green lights, wherein the red light indicated an out-of-tolerance condition and the green light indicated a within-tolerance condition.
  • the use of such indicator lights may be very useful. For example, through use of the indicator lights 40, an out-of-tolerance event may be quickly identified as soon as the housing 10 is removed from the borehole. In that case, analysis of the data acquired by the devices in the housing 10, e.g., sensors, may be given a very high priority as an out-of-tolerance condition is indicated. Absent the use of such good/bad indicator lights, the analysis of the acquired data may be delayed. Such delays may be very problematic in many situations if corrective actions are delayed.
