    Abstract: An imaging system includes a mirror assembly. An imager is centrally disposed on the mirror assembly and configured to acquire an image of a biometric feature of a vehicle occupant within a field of view of the imager. A first light source is disposed within the mirror assembly and configured to project a ray of light onto a target surface corresponding to an eye of the vehicle occupant. The first light source is spaced from the target surface by a first distance. The first light source is spaced from the imager by a second distance. The ray of light forms an angle of incidence having legs extending from the target surface to the first light source and to the imager, and wherein the first distance and the second distance are operable to define the angle of incidence in the range of 5° to 15°.

    Abstract: A monitoring system that includes an imaging device. The imaging device includes a first exposure profile and a second exposure profile. An illumination source is configured to emit at least one of infrared (IR) or near infrared (NIR) illumination. A control system is configured to alternate between the first exposure profile and the second exposure profile in accordance with a first pattern. The first exposure profile corresponds to the emission of illumination from the illumination source and the second exposure profile corresponds to ambient lighting.

    Abstract: A system for calibrating a driver monitoring system in a vehicle comprises a rearview assembly comprising a housing, a mount secured to a vehicle surface, and a barrel extending between the housing and the mount; an imager disposed in the rearview assembly; a processor in communication with the imager; a memory comprising a file containing information on stationary landmarks proximate the imager; and a controller operable to: receive images of the vehicle's interior and calibrate the imager by identifying a substantially stationary landmark in a first image used during an initial calibration; wherein the controller is configured to re-calibrate the driver monitoring operations based, at least in part, on a detection of the substantially stationary landmark being in a different location in a second image relative to the first image. One of the ends of the barrel is connected with a moveable joint.

    Abstract: An imaging assembly for use in a vehicle is disclosed. The imaging assembly may include an image sensor configured to capture image data and an electro-optic element configured to selectively control a range of wavelengths corresponding to light in a near infrared (NIR) range of light entering the image sensor. The electro-optic element may include a first portion configured to absorb the range of wavelengths entering the image sensor and a second portion configured to absorb the range of wavelengths entering the image sensor in a first state and to transmit the range of wavelengths entering the image sensor in a second state. The second portion may be electrically isolated from the first portion. A controller may be in communication with the image sensor and the electro-optic element. The controller may be operable to switch the second portion between the first state and the second state.

    Abstract: An asymmetrically reflective member is disclosed. This asymmetrically reflective member may be utilized in a rearview assembly to hide an imager disposed there behind. The member may comprise a substrate and an asymmetric transflective coating. The substrate may have a first side and a second side. The asymmetric transflective coating may be associated with the substrate. Additionally, the asymmetric transflective coating may have a transflective layer, a plurality of dielectric layers, and one or more absorptive layers interleaved with the plurality of dielectric layers. Further, the member may have a first side and a second side. The reflectance of the first side may be substantially greater than the reflectance of the second side.

    Abstract: An imaging system and method are provided herein. A first light source is configured to project a first illumination onto a vehicle occupant. A second light source is configured to project a second illumination onto the vehicle occupant. An imager is configured to acquire one or more images of a biometric feature of the vehicle occupant and generate image data corresponding to the one or more acquired images. The imager is further configured with a variable field of view based on which of the first and second light sources is activated.
