## Abstract

A window system includes a window that moves between a closed position and an open position, and a pressure-sensitive material disposed on an edge of the window. An object detection method includes moving a window from a more open position to a less open position, and during the moving, detecting an electrical parameter using a pressure-sensitive material.

## Claims

### Claim 1

A window system, comprising:
a window that moves between a closed position and an open position; and
a pressure-sensitive material disposed on an edge of the window, wherein the pressure-sensitive material includes at least two before pressure is applied strands that are in contact with each other twisted.

### Claim 2 (depends on 1)

The window system of claim 1, wherein the pressure-sensitive material is a pressure-sensitive cord.

### Claim 3 (depends on 1)

The window system of claim 1, further comprising a control module configured to stop a movement of the window in response to a change in a resistance associated with the pressure-sensitive material.

### Claim 4 (depends on 3)

The window system of claim 3, wherein the control module is a door control module.

### Claim 5 (depends on 1)

The window system of claim 1, wherein the edge is exposed when the window is in an open position.

### Claim 6 (depends on 1)

The window system of claim 1, wherein the edge faces vertically upward.

### Claim 7 (depends on 1)

The window system of claim 1, wherein the pressure-sensitive material is electrically conductive.

### Claim 8 (depends on 1)

The window system of claim 1, wherein the pressure-sensitive material is electrically coupled to a door control module.

### Claim 9 (depends on 1)

The window system of claim 1, wherein the window is a door window.

### Claim 10 (depends on 9)

The window system of claim 9, further comprising a tube that holds the pressure-sensitive material.

### Claim 11 (depends on 1)

The window system of claim 1, wherein the at least two strands are braided.

### Claim 12 (depends on 1)

The window system of claim 1, wherein the at least two strands are plaited.

### Claim 13 (depends on 1)

The window system of claim 1, wherein the at least two strands are twisted to establish a plurality of crossing points where the at least two strands are in contact with each other.

### Claim 14

A window system, comprising:
a window that moves between a closed position and an open position;
a tube secured to an edge of the window;
at least one first strand of a pressure sensitive material, the at least one first strand disposed within the tube; and
at least one second strand of the pressure sensitive material, the at least one second strand disposed within the tube, the at least one first strand intertwined with the at least one second strand to establish a plurality of crossing points where the at least one first strand contacts the at least one second strand before pressure is applied.

### Claim 15 (depends on 14)

The window system of claim 14, wherein the at least one first strand is braided with the at least one second strand.

### Claim 16 (depends on 14)

The window system of claim 14, wherein the tube is a Teflon tube.

### Claim 17 (depends on 14)

The window system of claim 14, wherein the at least one first strand is twisted with the at least one second strand to establish the plurality of crossing points.
