Abstract
Official abstract text for this publication.
A cold-test system for testing a camera at a cold temperature includes a test-chamber with a window, a nozzle, and a recirculator. The window is installed in the test-chamber so the camera is provided with a view of a test-target outside of the test-chamber. The nozzle is located proximate to a first edge of the window. The nozzle is configured to direct air from an air-source in a first direction and adjacent to an outside-surface of the window. The recirculator is located proximate to a second edge of the window opposite the first edge. The recirculator is configured to receive the air moving in the first direction and re-direct that air in a second direction opposite the first direction and adjacent to the air moving in the first direction opposite the window. The nozzle and the recirculator cooperate to form a bi-directional air-curtain proximate to the outside-surface.
First claim
Opening claim text (preview).
We claim: 1. A cold-test system for testing a camera at a cold temperature, said system comprising: a test-chamber configured to establish a cold temperature for testing a camera therein; a window installed in the test-chamber so the camera is provided with a view of a test-target outside of the test-chamber; a nozzle located proximate to a first edge of the window, said nozzle configured to direct air from an air-source in a first direction parallel to an outside-surface of the window, said outside-surface characterized as outside the test-chamber; and a recirculator located proximate to a second edge of the window opposite the first edge, said recirculator configured to receive the air from the nozzle moving in the first direction and re-direct that same air in a second direction opposite the first direction and adjacent to the air moving in the first direction opposite the window. 2. The system in accordance with claim 1 , wherein the nozzle and the recirculator cooperate to form a bi-directional air-curtain proximate to the outside-surface. 3. The system in accordance with claim 1 , wherein the window is characterized as consisting of a single-layer of transparent material. 4. The system in accordance with claim 1 , wherein the system includes a source-heater operable to heat air from the air-source that is emitted by the nozzle. 5. The system in accordance with claim 1 , wherein the system includes a recirculator-heater operable to heat air passing through the recirculator. 6. An apparatus to maintain a surface-temperature of an outside-surface of a window of a test-chamber greater than a dew-point temperature, said apparatus comprising: a nozzle located proximate to a first edge of the window, said nozzle configured to direct air from an air-source in a first direction parallel to an outside-surface of the window, said outside-surface characterized as outside a test-chamber; and a recirculator located proximate to a second edge of the window opposite the first edge, said recirculator configured to receive the air from the nozzle moving in the first direction and re-direct that same air in a second direction opposite the first direction and adjacent to the air moving in the first direction opposite the window. 7. The apparatus in accordance with claim 6 , wherein the nozzle and the recirculator cooperate to form a bi-directional air-curtain proximate to the outside-surface. 8. The apparatus in accordance with claim 6 , wherein the apparatus includes a source-heater operable to heat air from the air-source that is emitted by the nozzle. 9. The apparatus in accordance with claim 6 , wherein the apparatus includes a recirculator-heater operable to heat air passing through the recirculator.
