Abstract: The techniques disclosed herein provide apparatus, methods and systems that adaptively adjust the signal waveform (or waveshape) of the drive signal to a slow-scan mirror to compensate for non-linearities observed in the slow-scan feedback signal from a slow-scan mirror. Over large scan angles and high temperatures, the slow-scan mirror in a laser beam scanning device may exhibit a nonlinear response to the drive signal that results in poor image quality issues such as bright lines, bands in the display image, and image distortion. The presently disclosed technologies track the linearity performance of the overall system by detecting non-linearities in waveform of the slow-scan feedback signal real time, and consequently apply a pre-distortion to the drive waveform to compensate for these detected non-linearities. The parameters, logic and blocks of the control may be implemented in hardware, software or combinations thereof.

In response to a determination that the position of the peer input device is less than a threshold distance, the processor may generate a collision alert on the display device via the first transceiver.
