Mobile plant proximity detection and warning system
First Claim
1. A movement detection and warning system comprising a transmitter for transmitting an infra-red signal in association with die occurrence of an event or an object, the signal being adapted fir triggering a detector, said transmitter being mounted on a moveable vehicle, said movable vehicle being movable wit respect to the detector, said detector being tuned to only detect the infra-red signal transmitted by the detector when the detector is located within a predetermined distance from the transmitter, said detector activating an alarm for providing a warning to a person in the vicinity of the alarm in response to being triggered by the transmitted infra-red signal thereby providing an early and distinct warning to the person in the vicinity of the detector in order to eliminate or reduce the chances of the person sustaining injury, wherein the infra-red signal is transmitted through substantially 360°
- around the transmitter.

Abstract
A movement detection and warning system is provided and includes a transmitter means for transmitting a signal in association with an event or an object. The signal is adapted for triggering a detector means. The detector means is tuned to only detect the signal transmitted by the transmitter means when the detector is located within a predetermined distance from the transmitter means. The detector means activates an alarm means in response to being triggered by the transmitted signal thereby providing an early and distinct warning to people in the vicinity of the detector in order to eliminate or reduce the chances of the person sustaining injury. According to another aspect of the present invention there is provided a method of warning a person of the proximity of an object or event. According to the method, the object or event is associated with a transmitter means for transmitting a signal. The signal triggers a detector means and the detector is tuned to only detect the signal transmitted by the transmitter means. When the person and object or event are located within a predetermined distance from each other, the transmitter means transmits a signal to the detector means. In response, the detector means activates an alarm means in order to provide an early and distinct warning to the person in the vicinity of the object or event to alert the person to the presence of the object or event.

30. A movement detection and warning system for alerting a person to the close proximity of a moving vehicle, said system including a transmitter for transmitting an encoded infrared signal through substantially 360°
- round the transmitter for a preset time for triggering a detector, said transmitter being mounted on the vehicle so that the transmitter moves in accordance with movement of the vehicle so as to move with respect to the detector, said encoded infrared signal having a relatively narrow dimension in the substantially horizontal plane and a relatively wider dimension in the substantially vertical plane, said detector being tuned to detect the encoded infrared signal transmitted by the transmitter only when the detector is located within a predetermined distance from the transmitter and the infrared signal has been transmitted for the preset time, wherein when the transmitter is located within the predetermined distance from the detector, an alarm is activated in response to the detector sensing the encoded infrared signal for the preset time so as to provide an early and distinct warning to the person in the vicinity of the vehicle in order to eliminate or reduce the chances of the person sustaining injury.
