Abstract

There is disclosed a method and apparatus for deploying a mirror assembly from a recessed position that includes rotating the mirror assembly in a first direction about a first axis, the mirror assembly coupled proximate the first axis to at least one lifting arm and rotating each lifting arm in a second direction about a second axis such that the mirror assembly moves to an operational position. The first direction may be opposite from the second direction.

Claims

1. A method for projecting an image, comprising:

rotating a mirror assembly recessed within a dash of an automobile in a first direction about a first axis, the mirror assembly coupled proximate the first axis to at least one lifting arm;

rotating each lifting arm in a second direction about a second axis such that the mirror assembly moves to an operational position that is not recessed within a dash of an automobile; and

reflecting a visible image onto an imaging mirror of the mirror assembly.

2. A method for projecting an image, comprising:

rotating a mirror assembly recessed within, and having a surface substantially flush with a surface of, a dash of an automobile in a first direction about a first axis, the mirror assembly coupled proximate the first axis to at least one lifting arm;

rotating each lifting arm in a second direction about a second axis such that the mirror assembly moves to an operational position that is not recessed within a dash of an automobile;

directing energy from a scene toward a detector;

receiving energy from a portion of the scene at each of a plurality of detector elements;

converting the energy received at each detector element into information representative of the received energy; and

forming a visible image using the information representative of the received energy.

3. The method of claim 2, further comprising projecting the visible image onto a fold mirror and reflecting the visible image to an imaging mirror of the mirror assembly using the fold mirror.

4. A system for projecting an image, comprising:

a mirror assembly recessed within a dash of an automobile and coupled proximate a first axis to at least one lifting arm, the mirror assembly operable to rotate in a first direction about the first axis;

wherein each lifting arm operates to rotate in a second direction about a second axis such that the mirror assembly moves to an operational position that is not recessed within a dash of an automobile; and

a fold member operable to reflect a visible image onto an imaging mirror of the mirror assembly.

5. A system for projecting an image, comprising:

a minor assembly recessed within a dash of an automobile and coupled proximate a first axis to at least one lifting arm, the mirror assembly operable to rotate in a first direction about the first axis;

wherein each lifting arm operates to rotate in a second direction about a second axis such that the minor assembly moves to an operational position that is not recessed within a dash of an automobile;

a lens system operable to direct energy from a scene toward a detector;

a display unit coupled to the detector, the display unit operable to form a visible image using information received from the detector; and

wherein the detector includes an array of detector elements, each detector element operable to receive energy from a portion of the scene and to convert the received energy into information representative of the received energy and to send the information associated with at least some of the detector elements to the display unit.

6. The system of claim 5, wherein the display unit comprises a liquid crystal display operable to project the visible image onto a fold minor, the fold minor configured to reflect the visible image to an imaging mirror of the mirror assembly.
