Abstract

A vehicle wiper system includes a plurality of first sensor elements, an adjustable wiper, and a second sensor. The plurality of first sensor elements is configured to be disposed at a periphery of a vehicle window to form a boundary. The adjustable wiper has a distal end and a proximal end, and an adjustment mechanism that enables a distance between the distal end and the proximal end to change. The adjustable wiper is configured to travel along a windshield to define a wiper path. The second sensor element is disposed adjacent the distal end, and is configured to operate in conjunction with the first sensor element to adjust the adjustable wiper such that a distance between the distal end and the proximal end changes, and a distance between the distal end of the wiper and the boundary remains substantially consistent as the adjustable wiper travels along the wiper path.

First claim

What is claimed is:

1. A vehicle wiper system, comprising:
a plurality of first sensor elements configured to be disposed at a periphery of a vehicle window to form a boundary;
an adjustable wiper having a distal end and a proximal end, and having an adjustment mechanism that enables a distance between the distal end and the proximal end to change, the adjustable wiper configured to travel along the vehicle window to define a wiper path; and
a second sensor element disposed adjacent the distal end of the adjustable wiper blade, and configured to operate in conjunction with the first sensor element to adjust the adjustable wiper such that a distance between the distal end and the proximal end changes, and a distance between the distal end of the wiper and the boundary remains substantially consistent as the adjustable wiper travels along the wiper path.

2. The vehicle wiper system according to claim 1 , wherein
the second sensor is configured to transmit a signal in a direction generally parallel to a surface of the vehicle window.

3. The vehicle wiper system according to claim 1 , wherein
the second sensor is one of an infrared sensor, a laser, and a photo sensor.

4. The vehicle wiper system according to claim 1 , wherein
the first sensor is one of an infrared sensor, a laser, and a photo sensor.

5. The vehicle wiper system according to claim 1 , wherein
the plurality of first sensor elements are configured to be disposed within a trim element of the vehicle.

6. The vehicle wiper system according to claim 1 , wherein
the plurality of first sensor elements are disposed within a sensor attaching mechanism configured to be removably attached adjacent the periphery of the vehicle window.

7. The vehicle wiper system according to claim 1 , wherein
the adjustment mechanism is configured to move the distal end of the adjustable wiper in a longitudinal direction.

8. The vehicle wiper system according to claim 1 , wherein
the adjustable wiper includes a first wiper part and a second wiper part, and the second wiper part is configured to move relative to the first wiper part.

9. The vehicle wiper system according to claim 1 , wherein
the adjustable wiper includes a wiper contact blade disposed between the distal end and the proximal end and configured to contact the window, the wiper contact blade being capable of adjusting a contact length thereof during a wiper operation.

10. A vehicle wiper system, comprising:
a plurality of first sensor elements configured to be disposed at a periphery of a vehicle window so as to form a boundary;
an adjustable wiper having a distal end and a proximal end, and having an adjustment mechanism that enables a distance between the distal end and the proximal end to change;
a second sensor element disposed adjacent the distal end of the adjustable wiper blade, and configured to communicate with the plurality of first sensor elements; and
a controller in communication with the second sensor, and programmed to determine the distance between the second sensor element and each of the first sensor elements, and programed to adjust the adjustable wiper such that a distance between the distal end and the proximal end changes to maintain a predetermined distance between the distal end and the boundary of the vehicle window during operation of the vehicle wiper system, such that the predetermined distance remains substantially consistent as the adjustable wiper travels along a wiper path.

11. The vehicle wiper system according to claim 10 , wherein
the plurality of first sensor elements are configured to be disposed within a trim element of the vehicle.

12. The vehicle wiper system according to claim 10 , wherein
the plurality of first sensor elements are disposed within a sensor attaching mechanism configured to be removably attached adjacent the periphery of the vehicle window.

13. The vehicle wiper system according to claim 10 , wherein
the adjustable wiper includes a first wiper part and a second wiper part, and the second wiper part is configured to move relative to the first wiper part in a longitudinal direction of the adjustable wiper.

14. The vehicle wiper system according to claim 10 , wherein the adjustable wiper includes a wiper contact blade disposed between the distal end and the proximal end and configured to contact the window, the wiper contact blade being capable of adjusting a contact length thereof during a wiper operation.
