Abstract: A method and system for steering an insertion tube of a video inspection device is disclosed for detecting a precise steering request made by displacing a pointing device from its stationary position and then returning the pointing device to or near its stationary position within a short interval of time. This precise steering request is then used by the video inspection device to steer the insertion tube a fixed distance in a direction based on the direction of the displacement of the pointing device for precise positioning of the camera head of the insertion tube.

Abstract: A method for reducing power consumption in a computer system is provided wherein the computer system includes a system bus interface connected by a signal line to a power supply and/or clock circuitry for the central processing unit, each having the capability to change the characteristic of its output responsive to the signal line for placing the central processing unit in a low-power consuming state. The system bus interface chip further including a storage location and counter for storing the type and quantity of interrupt assertions during the period of time when the central processing unit is in the low power consuming state.The system software determines the desired period of time to put the central processing unit into the low-power consuming safe and does not return it to normal power consuming state until the time period has expired, a non interval clock interrupt is asserted, or another critical event occurs that needs immediate CPU attention.
