Abstract: A warning device of the flashing beacon type (2) is provided with a dual light source (14, 16), typically in the form of two LEDs arranged in back to back relationship, in which the light from one light source (14) is transmitted directly from the beacon whereas the light from the other light source (16) is reflected by a compound reflector (18, 20) from a direction which is essentially opposite the direction of the light from the first source to a direction which is the same as or substantially parallel to the direction of the first source so as to produce a compound beam of illumination having a relatively darker first peripheral part, a relatively more intense central part followed by a relatively less intense third peripheral part. The two light sources and the compound reflector rotates in unison with each other to produce flashes of illumination to a person observing the beacon from a remote location to the beacon.

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.
