  • the sensor 40 may be disposed within the inner chamber 44 such that the sensor 40 and the shield 38 define a void 46 extending therebetween.
  • the shield 38 may include an inner surface 48, an outer surface 50, a peripheral surface 51, and a cleaning system 52.
  • the inner surface 48 may define a concave profile
  • the outer surface 50 may define a convex profile.
  • the curvature of the concave inner surface 48 may be substantially concentric to the curvature of the convex outer surface 50.
  • the shield 38 including the inner surface 48 and the outer surface 50, may be disposed between the sensor 40 and the area 22 surrounding the vehicle 10, such that the inner surface 48 is exposed to the inner chamber 44, and the outer surface 50 is exposed to the area 22 surrounding the vehicle 10. Accordingly, the shield 38 (e.g., the outer surface 50) separates and protects the sensor 40 from the area 22 surrounding the vehicle 10, while also allowing the sensor 40 to sense the area 22 surrounding the vehicle 10.
  • the peripheral surface 51 may include an upper portion 51a, a lower portion 51b opposite the upper portion 51a, a first end portion 51c extending from the upper portion 51a to the lower portion 51b, and a second end portion 5 Id opposite the first end portion 51c and extending from the upper portion 51a to the lower portion 51b.

  • the first concave and convex profile may each define a first radius of curvature, and the second concave and convex profile may each define a second radius of curvature. In some implementations, the first radii of curvature are greater than the second radii of curvature.
  • the shield 38 may be formed at least in part from a transparent and/or translucent material.
  • the shield 38 may be formed at least in part from a plastic, glass, acrylic, or polycarbonate material.
  • the shield 38 includes a material(s) having selectively controllable light transmission properties.
  • the shield 38 may include a material having light transmission properties that are modified when a stimulus (e.g., a voltage, light, heat, etc.) is applied to the shield 38.
  • the shield 38 may include a switchable privacy glass, such as POLYVISIONTM, manufactured by Polytronix, Inc. of Richardson, Texas.
  • the shield 38 may be transparent and/or translucent when the sensor assembly 20 is switched to the first state (FIG. 2 A), and opaque when the sensor assembly 20 is switched to the second state (FIG. 2B).
  • the stimulus may be applied when the sensor assembly 20 is in the first state (FIG. 2A) and removed when the sensor assembly 20 is in the second state (FIG. 2B). Accordingly, when the sensor assembly 20 is in the second state, light may be inhibited from passing through the shield 38 such that the sensor 40 is concealed by, and/or not visible through, the shield 38.
  • the switchable privacy glass of the shield 38 may include a film applied (i) on the inner surface 48 of the shield 38, (ii) and/or on the outer surface 50 of the shield 38, and/or between the inner surface 48 and the outer surface 50 of the shield in a sandwiched or layered configuration. Applying the switchable privacy glass (e.g., the film) to the inner surface 48 or between the inner surface 48 and the outer surface 50 may protect the switchable privacy glass from damage that may be caused by dirt and other debris in the area 22 surrounding the vehicle 10.
  • the switchable privacy glass e.g., the film
  • the shield 38 may include liquid crystal molecules that are randomly oriented when a stimulus such as voltage is not applied to the shield 38. Accordingly, in this state, the liquid crystal molecules scatter incident light and provide the shield 38 with an opaque appearance (FIG. 2B). Conversely, when a stimulus such as voltage is applied to the shield 38, the liquid crystal molecules line up, thereby allowing incident light to pass through the shield 38 (FIG. 2 A). In this state, the shield 38 appears clear and permits use of the sensor 40 disposed within the housing 30. While the shield 38 is described as being opaque in the second state, the shield 38 may include a color that matches the color of the vehicle 10 and/or the bezel 30 surrounding the shield 38 when in the second state.
  • the shield 38 may be formed at least in part by a material such as glass having a color that is similar to the color of the surrounding vehicle structure and/or the bezel 30. Accordingly, when the shield 38 is in the second state (FIG. 2B) and the sensor 40 is not visible, the shield 38 blends into the vehicle structure and gives the appearance of being part of a painted, external surface of the vehicle 10. Namely, the shield 38 has the same or approximately the same color as the surrounding structure of the vehicle 10 when in the second state. [0039] In some configurations, the shield 38 may include a two-way mirror.
  • the shield 38 may be formed at least in part from a two-way mirror, such that light is permitted to pass through the shield 38 in a direction extending from the outer surface 50, and/or from the peripheral surface 51, to the inner surface 48.
  • the outer surface 50 includes a reflective coating, such that the outer surface 50 and/or the peripheral surface 51 is partially reflective and partially transparent. Accordingly, when the area 22 surrounding the vehicle 10 is brightly lit relative to the chamber 44, the sensor 40 may be permitted to sense a condition in the area 22 while also being invisible within the chamber 44 from the area 22.
  • the senor 40 may be invisible in a direction extending from the outer surface 50, and/or from the peripheral surface 51, to the inner surface 48, while being able to sense the area 22 in a direction extending from the inner surface 48 to the outer surface 50 and/or to the peripheral surface 51.
