Claims
- 1. A sensor mounting device for mounting a sensor on a surface of a windshield, said device comprising:
- a) a vacuum chamber defining a cavity for temporarily receiving a sensor, said vacuum chamber including an aperture to facilitate the insertion and removal of the sensor from the cavity of said vacuum chamber;
- b) movable positioning means disposed in the cavity of said vacuum chamber for securing the sensor in the cavity such that an adhesive surface of the sensor is adjacent the aperture;
- c) sealing means formed about the aperture in said vacuum chamber for sealably engaging a windshield when the aperture is positioned adjacent the windshield;
- d) vacuum means connected to said vacuum chamber for selectively creating a vacuum in the cavity of said vacuum chamber when the vacuum chamber is sealably engaging the windshield; and
- e) means for selectively driving the positioning means while a vacuum is maintained in the cavity of the vacuum chamber such that the adhesive surface of the sensor is secured to the windshield in a vacuum.
- 2. The sensor mounting device defined in claim 1 including a controller in electrical communication with said vacuum means and said drive means for controlling the operation of said vacuum means and said drive means.
- 3. The sensor mounting device defined in claim 2 wherein said controller includes a switching means mounted on said vacuum chamber for starting and stopping said vacuum means and said drive means.
- 4. The sensor mounting device defined in claim 2 wherein said vacuum means includes a valve in electrical communication with said controller for controlling pressure in said vacuum chamber, said valve having an output port communicating with the cavity of said vacuum chamber and two input ports, a first input port connected to a vacuum source and a second input port open to atmospheric pressure.
- 5. The sensor mounting device defined in claim 2 including a pressure sensor in electrical communication with said controller and mounted on said vacuum chamber for monitoring the pressure in said cavity.
- 6. The sensor mounting device defined in claim 2 wherein said positioning means includes an electrical connector extending from said positioning means for electrically connecting the sensor to said controller, said controller transmitting signals to said sensor to verify optical operation of the sensor upon securing the sensor to the windshield.
- 7. The sensor mounting device defined in claim 1 wherein said drive means includes a shaft extending into said vacuum chamber opposite the aperture, said shaft including a first end connected to said positioning means in the cavity of said vacuum chamber and a second end extending from said vacuum chamber, whereby the shaft may be moved longitudinally to secure the sensor to the windshield and a seal mounted to sealably engage said shaft and said vacuum chamber.
- 8. The sensor mounting device defined in claim 6 wherein said drive means includes a latching means to lock the shaft in position while a vacuum is created in the chamber and a solenoid valve which may be selectively energized to release the latching means for longitudinally positioning said shaft.
- 9. The sensor mounting device defined in claim 6 wherein said drive means includes a pneumatic drive connected to the second end of said shaft for longitudinally positioning said shaft.
- 10. The sensor mounting device defined in claim 6 wherein said positioning means includes a base mounted on the first end of said shaft in the cavity of said vacuum chamber, the base including a plurality of spring clips for securing the sensor to the base such that the adhesive surface of the sensor is adjacent the aperture of said vacuum chamber.
- 11. The sensor mounting device defined in claim 6 wherein said positioning means includes a base mounted on the first end of said shaft in the cavity of said vacuum chamber, the base including a planar, compressible pad mounted on said base to facilitate alignment of the adhesive surface of the sensor with the windshield.
- 12. The sensor mounting device defined in claim 1 including a means, mounted on said vacuum chamber, for locating a mounting position on the interior surface of the windshield for securing the sensor.
- 13. The sensor mounting device defined in claim 12 wherein said means for locating a mounting position includes a fixture mounted on said vacuum chamber for engaging a mirror mount on the interior surface of the windshield.
- 14. A device for mounting a sensor having an adhesive surface on a surface of a windshield, said device comprising:
- a) a vacuum chamber defining a cavity for temporarily receiving a sensor, said vacuum chamber including an aperture to facilitate the insertion and removal of the sensor from the cavity of said vacuum chamber;
- b) drive means for pressing the sensor against the windshield, said drive means including a shaft extending through said vacuum chamber opposite the aperture, said shaft including a first end positioned in the cavity of said vacuum chamber and a second end extending from said vacuum chamber and a seal mounted to sealably engage said shaft and said vacuum chamber;
- c) a base mounted transversely on the first end of said shaft in the cavity of said vacuum chamber, said base including a plurality of spring clips for securing the sensor to the base such that an adhesive surface of the sensor is adjacent the aperture of said vacuum chamber;
- d) sealing means formed about the aperture in said vacuum chamber for sealably engaging a windshield when the aperture is positioned adjacent the windshield;
- e) vacuum means connected to said vacuum chamber for selectively creating a vacuum in the cavity of said vacuum chamber when the vacuum chamber is sealably engaging the windshield, said vacuum means including a valve for controlling pressure in said vacuum chamber, the valve having an output port communicating with the cavity of said vacuum chamber and two input ports, a first input port connected to a vacuum source and a second input port open to atmospheric pressure; and
- f) control means in electrical communication with said drive means and said vacuum means for controlling the operation of said drive means and said vacuum means, said control means including a pressure sensor for monitoring the pressure in the cavity of said vacuum chamber, whereby said controller selectively controls the longitudinal movement and force of the shaft while a vacuum is maintained in the cavity of the vacuum chamber such that the adhesive surface of the sensor is secured to the windshield in a vacuum.
