Patent Images
1. A self-contained collision warning device comprising:
- a support structure supporting a power supply, a microprocessor, a first motion sensor having a first field of view (FOV), a second motion sensor having a second FOV, a first indicator, and a second indicator wherein;
the first motion sensor and the first indicator are positioned on a first side of the support structure;
the second motion sensor and the second indicator are positioned on a second side of the support structure such that the first FOV and the second FOV are non-overlapping;
the power supply provides power to the microprocessor, the first motion sensor, the second motion sensor, the first indicator, the second motion sensor, and the second indicator; and
the microprocessor is operationally coupled to the first motion sensor, the second motion sensor, the first indicator, and the second indicator and activates the first indicator and the second indicator when both the first motion sensor and the second motion sensor detect motion.

Abstract
A self-contained collision warning device warns of possible collisions between people and between people and moving objects on opposite sides of doors and other visual barriers. Motion sensors detect the presence of people or moving objects and activate indicators that warn of the presence of unseen people and moving objects. The device can be mounted to a door or wall without modification to the door or wall or access to electrical power.
