    Abstract: Examples of an imaging device (100) are described herein. In an example, the imaging device (100) includes a drive control assembly (110), a first drive assembly (106), a second drive assembly (108), a movable carriage (102), and a locking mechanism (112). The drive control assembly (110) can be used to regulate transmission of drive from an actuator (200) to the first drive assembly (106) and the second drive assembly (108). The locking mechanism (112) can lock the drive control assembly (110) in an engaged position with the first drive assembly (106) or the second drive assembly (108). The movable carriage (102) can actuate the locking mechanism (112) to lock the drive control assembly (110) in the engaged position.

    Abstract: Various embodiments of an optical proximity sensor and corresponding circuits and methods for measuring small AC signal currents arising from the detection of pulsed AC light signals emitted by a light emitter and reflected from an object to detected in the presence of larger ambient light DC current signals are disclosed. Circuits and corresponding methods are described that improve the dynamic range, sensitivity and detection range of an optical proximity sensor by cancelling the contributions of DC current signals arising from ambient light signals that otherwise would dominate the detected small AC signal currents. The DC signal cancellation occurs in a differential amplifier circuit before small AC signal currents are provided to an analog-to-digital converter. The circuits and methods may be implemented using conventional CMOS design and manufacturing techniques and processes.
