The apparatus comprises two identical control devices (11a, 11b) which generate activation commands (24a, 24b) for preventive lights (2a-2e) signalling the progress of a vehicle (1). Each of the control devices (11a, 11b) is provided with driver-operated inhibiting members (17a, 17b, 18) for inhibiting the generation of at least one of said activation commands (24a, 24b) which is to be inhibited. The control devices (11a, 11b) can be used in a complementary fashion from an activation or deactivation of the inhibiting members (17a, 17b, 18) which they respectively include, by distribution between the control devices (11a, 11b) of the activation commands (24a, 24b) which they respectively emit to activate preventive lights (2a-2e) which include at least one piece of preventive equipment (4).

An article of clothing includes user-protection circuitry, integrated into the article of clothing. The user-protection circuitry includes condition-detection circuitry, which, in operation, generates one or more indications related to an environment of the article of clothing. The user-protection circuitry also includes broadcast circuitry including at least one pulsing device, and control circuitry. The control circuitry, in operation, activates the broadcast circuitry based on the one or more indications related to the environment of the article of clothing generated by the condition-detection circuitry.

The present invention relates to a portable traffic management system comprising a portable traffic signal assembly; a portable signal assembly; and a control unit in wireless communication with the portable traffic signal assembly and the portable signal assembly. The present invention alleviates one or more of the problems associated with the presently available traffic management systems.

Electronic light emitting flares and related methods. Flares of the present invention include various features such as self-synchronization, remote control, motion-actuated or percussion-actuated features, dynamic shifting between side-emitting and top-emitting light emitters in response to changes in positional orientation (e.g., vertical vs. horizontal) of the flare; overrides to cause continued emission from side-emitting or top-emitting light emitters irrespective of changes in the flare's positional orientation; use of the flare(s) for illumination of traffic cones and other hazard marking or traffic safety objects or devices, group on/off features, frequency specificity to facilitate use of separate groups of flares in proximity to one another, selection and changing of flashing patterns and others.

The present disclosure concerns a warning device comprising a warning body having a longitudinal axis and comprising a light-emitting assembly; and a collapsible stand configurable in a compacted configuration and in a warning configuration in which the light-emitting assembly is at least partially visible. The collapsible stand comprises a handle sleeve mounted to and slidable along the warning body and legs pivotably mounted to the handle sleeve, the legs being juxtaposed against the warning body when the collapsible stand is in the compacted configuration to cover the warning body and the legs extending outwardly and downwardly when the collapsible stand is in the warning configuration, the collapsible stand being configurable between the compacted configuration and the warning configuration by sliding the handle sleeve along the warning body. The disclosure also concerns a warning assembly comprising such a warning device and a method of emitting a warning light signal.

A handheld warning sign including front and back with at least one side having a predetermined color and warning information. A handle member of predetermined length is fastened to the bottom of the sign member enabling it to be handheld. A longer pole extension structure can be attached to the sign handle member enabling it to extend to the ground allowing the sign unit to be used a handheld road sign. An electronic sound device positioned within the handle member of the sign is connected to a battery and a off and on power switch on the handle member. When the sound device button on the handle member is pressed, the electronic sound device produce a warning sound such as a whistle, siren or other warning sounds to attract the attention of motorists or pedestrians so that they can safely follow the directions the safety personnel.

An attachment system for attachment to a signaling device includes an attachment member. The attachment member is formed of a ring-shape made of an elastic material and includes an annular base and at least one fin. The annular base includes an external peripheral edge and a central orifice defining an internal peripheral edge. The annular base also includes an annular lower face and an annular upper face. The fin projects from the external peripheral edge of the annular base. The attachment member is movable between a rest configuration in which the annular base is planar and extends in a main plane to allow insertion and positioning on the signaling device at a selected position, and a deformed configuration in which the annular base is non-planar in a deformed state in order to be able to match a peripheral area of the signaling device.

One or more techniques and/or systems are disclosed for alerting workers in a work zone of a potential intrusion by a vehicle. The example system can comprise a detection unit operable to mount to a work zone boundary marker. The detection unit monitors the work zone for intrusion by moving objects using the Doppler Effect. The detection unit can transmit an alarm signal to one or more personnel alerters, such as worn by workers. The personnel alerters can receive the alarm signal and activate an alert, such as an audible, visual, or other sensory alert. In this way, an alert is provided to personnel working in an established work zone that a moving object, such as a vehicle, has penetrated the work zone perimeter. This type of alert may provide the personnel the vital seconds needed to move to safety.
