Hinge sensor for barrier
First Claim
1. A method for determining direction of passage through an opening controlled by a barrier, comprising:
- detecting with a hinge sensor a closed position for the barrier, the hinge sensor being mounted to a hinge of the barrier, the hinge sensor having a physical fixed portion and a physical rotatable portion;
determining a position of the physical fixed portion relative to the hinge;
determining a position of the physical rotatable portion relative to the physical fixed portion using a measured value of the hinge sensor, the measured value of the hinge sensor comprising a change in angular position and a distance of separation between the physical rotatable portion and the physical fixed portion;
detecting with the hinge sensor the barrier changing from the closed position to an open position using the determined position of the physical fixed portion relative to the hinge and the determined position of the physical rotatable portion relative to the physical fixed portion;
detecting, via a motion sensor, a movement of an object through the opening based at least in part on the barrier changing from the closed position to the open position, wherein the hinge sensor comprises the motion sensor; and
determining a direction of the movement of the object through the opening based at least in part on a change in angular position and a distance of separation between the physical fixed portion and the physical rotatable portion, the movement occurring before and after the change in position of the barrier.

Abstract
Methods and systems are described for determining operation of an openable barrier and direction of movement of a person through an opening controlled by the barrier. A method includes detecting with a hinge sensor a closed position for the barrier, the hinge sensor being mounted to a hinge of the barrier, determining with the hinge sensor when the barrier changes position from the closed position to an open position, detecting with at least one motion sensor motion of an object in proximity to the opening, and determining a direction of movement of the object through the opening based on whether the motion is detected before or after detecting the change in position of the barrier.

16. A direction of movement detecting assembly, comprising:
-
a hinge sensor mounted to a hinge of a barrier operable to detect movement of the barrier, the hinge sensor having a physical fixed portion and a physical rotatable portion; the hinge sensor being operable to; determine a position of the physical fixed portion relative to the hinge; determine a position of the physical rotatable portion relative to the physical fixed portion using a measured value of the hinge sensor, the measured value of the hinge sensor comprising a change in angular position and a distance of separation between the physical rotatable portion and the physical fixed portion; and detect the barrier changing from a closed position to an open position using the determined position of the physical fixed portion relative to the hinge and the determined position of the physicall rotatable portion relative to the physical fixed portion; the hinge sensor comprising at least one motion sensor operable to; detect movement of an object through an opening of the barrier based at least in part on the changing from the closed position to the open position; and a controller operable to; determine a direction of the movement of the object through the opening based at least in part on a distance of separation between the physical fixed portion and the physical rotatable portion, the movement occurring before and after the change in position of the barrier. - View Dependent Claims (17, 18, 19)
