Abstract: A vehicular exterior rearview mirror assembly includes a mirror head pivotally mounted at a mounting base configured for attachment at a side of a vehicle. The mirror head accommodates a reflective element. A powerfold actuator is operable to pivot the mirror head relative to the mounting base between at least an extended position and a folded position. The powerfold actuator includes a primary detent state that is engaged to maintain the mirror head at the extended position when the mirror head is pivoted via the powerfold actuator to the extended position. When the mirror head is manually moved from the folded position to the extended position, the powerfold operator is in a secondary detent to maintain the mirror head at the extended position.

Abstract: Optical systems have uses, such as in spectrometers, for directing a beam. A spectrometer, for example, utilizes an optical system for directing an incident beam toward a sample and receiving a spectroscopy signal from the sample. In various implementations, for example, an optical system may be further configured to move a beam with respect to a target, such as a sample, and still provide a home position where the beam is directed in a stationary configuration. A self-homing (e.g., self-centering) optical system may provide a “home” position in which the beam is directed in a first stationary mode while still allowing a focused beam to be moved with respect to a target in a second dynamic mode.
