    摘要: A system comprising a sensing device and a capacitive sense array configured to track the position of a stylus and synchronize the capacitive sense array to the stylus transmit signal. The system is configured to track the position of both a stylus and a passive touch object. The system is further configured to track the position of the stylus using self capacitance sensing and track the position of the passive touch object using mutual capacitance sensing. The system further configured to modulate the stylus transmit signal to include additional data to support additional stylus functions.

    摘要: A system, fan controller and method for enhanced alert notification. Embodiments provide an effective mechanism for utilizing system fans to create alert tones or messages, where fan speed differentials may be adjusted to alter the frequency of the fan interference sounds. As such, existing hardware can be used to reduce cost by producing audible alerts which may be heard above ambient noise in a room with one or more electronic systems. Further, the frequency of the interference sounds may be altered to more clearly identify one or more systems to which a fault pertains.
