Abstract: Embodiments of the present invention provide a motor-driven mechanical system with a detection system to measure properties of a back channel and derive oscillatory characteristics of the mechanical system. Uses of the detection system may include calculating the resonant frequency of the mechanical system and a threshold drive DTH required to move the mechanical system from the starting mechanical stop position. System manufacturers often do not know the resonant frequency and DTH of their mechanical systems precisely. Therefore, the calculation of the specific mechanical system's resonant frequency and DTH rather than depending on the manufacturer's expected values improves precision in the mechanical system use. The backchannel calculations may be used either to replace or to improve corresponding pre-programmed values.

Abstract: This disclosure pertains to a system and method for calibrating a time-of-flight imaging system. The system includes a housing that houses light emitter, a light steering device, and a photosensitive element. The system also includes an optical waveguide or reflective element on an inner wall of the housing. The light steering device can be controlled to steer a beam of light from the light emitter to the optical waveguide. The optical waveguide or reflective element can direct the light from a known position on the wall of the housing to the photosensitive element.

Abstract: A drive signal for a motor-driven mechanical system has zero (or near zero) energy at an expected resonant frequency of the mechanical system. These techniques not only generate a drive signal with substantially no energy at the expected resonant frequency, they provide a zero-energy “notch” of sufficient width to tolerate systems in which the actual resonant frequency differs from the expected resonant frequencies.

Abstract: Embodiments of the present invention provide improved accuracy of displacement control by using a multi-segment transformation of an actuator's non-linear response. The present invention may set intermediate points to effectively divide the actuator response into multiple segments. Each segment may be assigned a transform function that represents the actuator's response in that particular segment. The present invention may operate in two modes, a calibration mode and a normal operations mode. During calibration mode, the intermediate points and the segment transforms may be set. During normal operations mode, a drive signal may be generated according to the calibrated set values.

Abstract: Embodiments of the present invention provide a drive signal for a motor-driven mechanical system whose frequency distribution has zero (or near zero) energy at the expected resonant frequency of the mechanical system. The drive signal may be provided as a pair of steps sufficient to activate movement of the mechanical system and then park the mechanical system at a destination position. The steps are spaced in time so as to have substantially zero energy at an expected resonant frequency fR of the mechanical system. The drive signal may be filtered to broaden a zero-energy notch at the expected resonant frequency fR.
