A self-applying braking apparatus to prevent wind-blown movement of a mobile device includes a main body, a resisting member, a retaining member, a pushing member, and a mounting member. The braking apparatus is mounted on an application device by the mounting member. The retaining member provides an elastic force to fix the main body on the application device. The resisting member is disposed on the main body and configured to abut the tarmac or ground to prevent the mobile device from moving. The pushing member is disposed on the main body and is configured to push the resisting member to abut the ground when blown by the wind or by turbulence from a passing vehicle in a predetermined direction, when greater than the elastic force. The braking apparatus prevents unwanted wind-blown movement.

An illuminated vehicle distress sign is disclosed herein. The illuminated vehicle distress sign includes an emergency signal device comprising a vehicle window attachment. The vehicle window attachment has a first shaft hingedly attached thereto and a second shaft hingedly attached to the first shaft which supports a rigid signaling placard at the distal end thereof. Additionally, the signaling placard includes a plurality of battery powered and multi-colored LED's disposed on the peripheral edges of the front and back faces thereof. Furthermore, the signaling placard may be provided in the form of a square or in the shape of a hand. Additionally, the LEDs disposed on the placard may be mounted in a configuration to form the word “HELP”. Other configurations and other sizes may be used.

A warning triangle structure includes a base, a triangle, a number of connecting rods, and a braking device. The triangle includes a bottom end and a top end opposite the bottom end. The bottom end is fixedly mounted to the base. Each of the connecting rods includes a first end and a second end. The first end is fixedly coupled to the base, and the second end is mounted with a rotatable support wheel. The braking device is installed at the second end of at least one of the connecting rods. The braking device includes a transmission shaft coupled to the support wheel. The braking device controls the support wheel to stop rotating by stopping the transmission shaft from rotating.

A lighting device equipped at all times in a vehicle, which can be used for camping and leisure and has a function of a safety warning light of the vehicle, according to the present invention, comprises: a rectangular-shaped fixing plate having a pair of first magnet members which are disposed horizontally; a “C”-shaped front insertion groove which is formed on the front surface of the fixing plate and is formed to be adjacent to the edges of the fixing plate excluding the upper or lower edge of the fixing plate; a “C”-shaped first support member which is selectively fixed to the front insertion groove and is installed rotatably toward the front surface with respect to the fixing plate by the medium of a hinge; a pair of side surface insertion grooves which are longitudinally formed on the respective sides of the fixing plate; a pair of second support members which are respectively coupled to the inside of the side surface insertion grooves by the medium of a hinge, and are unfolded in a direction opposite to the first support member; a light unit which has, on the rear surface thereof, a second magnet member coupled to the first magnet members, has a battery embedded therein, and has a lighting device on the front surface thereof; and a cover which is rotatably coupled to the light unit by the medium of a hinge so as to selectively cover the lighting device, wherein the lighting device may flicker when the lighting device is covered by the cover.

A worksite classification system and method for classifying persons at a worksite is disclosed. The worksite classification system can include a sensor system configured to capture images of persons located at the worksite. An electronic data processor communicatively coupled to the sensor system and comprising a computer readable storage medium having machine readable instructions that, when executed by the electronic data processor, cause the processor to: determine an identity of the persons based on one or more identifying characteristics associated with the persons; determine if the persons have authorization access to enter to one or more operational zones at the worksite based on the identity of the persons and an associated access level; and generate an alert notifying an operator when persons without authorization access enters the one or more operational zones.
