Abstract: Inputs to a projected or other type of displayed user interface are verified with a verification device that enhances input detection accuracy. For example, inputs at a projected keyboard are detected by an infrared curtain projected over the keyboard and breached by an end user finger as it strikes a key. The inputs are verified with a capacitive sensor device disposed below the keyboard that confirms a user touch. Alternatively, proximity sensing by the capacitive sensor measures distance and velocity associated with a finger to verify the inputs detected by breaching of the infrared curtain are intended inputs. Other verification devices may include an accelerometer that detects accelerations associated with inputs and three dimensional cameras that capture finger positions. Verification devices may be selectively enabled based upon power and accuracy constraints.

Abstract: An information handling system cooling fan has a vibration filter that tunes out predetermined fan vibration frequencies to reduce fan vibration transfer from the cooling fan to an information handling system chassis in a targeted frequency range. For example, a leaf spring and damper are biased between the cooling fan and a fan bay support so that stiffness of the spring attenuates selected vibration frequency ranges of the cooling fan bay subsystem, such as frequency ranges where the vibrations have the greatest amplitude or frequency ranges where the vibrations tend to damage other components of the information handling system. In one embodiment, a vibration source generates out-of-phase vibrations that cancel cooling fan vibrations to further reduce overall system vibration output.
