A self-assembling network is configured to automatically and dynamically connect devices used in operations carried out on or near roads bearing vehicle and pedestrian traffic. An automatic, ad hoc network connecting existing and new devices can be used to enhance safety by gathering and exchanging safety critical information. In some cases, existing equipment can be augmented with a network controller and radio frequency communications to permit the devices to join a wireless local network and exchange information over the network. New devices, including wearable devices, can be configured to act as nodes on the wireless local network. Establishing the relative position of vehicles, sensors, wearables, and other nodes on the disclosed ad hoc wireless network allows the coordination of functions based on position.

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.

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.

A system for detecting a vehicle traveling a designated direction of travel on a roadway includes a sign having a front surface and a back surface. The sign may include a sign boundary marker that is different in color than a color of the front surface. One or more light panels such as an LED light panel is affixed to the sign such as to its front surface. The light emitting elements may lie below a top plane of the light panel. A color of a top surface of the light panel matches a color on the front surface of the sign over which the light panel is placed. A vehicle motion detector or proximity detector is oriented in a direction and has a detection zone for detecting moving vehicles in proximity to the sign. The detector illuminates the lights of the light panel after detecting a moving vehicle in proximity to the sign.

The disclosure provides systems, devices, and associated methods for mitigating traumatic brain injury, injury to an ocular structure, or injury to the inner ear of a subject by applying pressure to one or more neck veins before and during an injurious event.

Embodiments relate to visibility-enhancing objects and systems. These embodiments include visibility-enhancing portions can include a reflective portion and/or a light source. In some embodiments, a connecter is adapted to removably attach a visibility-enhancing portion to a container. Such containers can include at least one strap, and the visibility-enhancing portion can be arranged between the container and one a strap, to extend at least partially beyond a perimeter of the container to increase visibility of the wearer.

One or more techniques and/or systems are disclosed for warning workers in a work zone of a potential intrusion by a vehicle. The example system can comprise a master device, coupled with one or more boundary markers using a tripwire. When the trip wire, and/or one of the boundary markers, is impacted with sufficient force, the tripwire is disengaged from the master device. Once disengaged, the master device can transmit a wireless alert signal to one or more portable alerter, such as worn by workers. The portable alerters can receive the signal and activate a personnel 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 potentially threatening vehicle has penetrated the work zone perimeter. This type of alert may provide the personnel the vital seconds needed to move to safety.

A method for safeguarding a self-driving, damaged vehicle includes independently detecting damage of the damaged vehicle by the damaged vehicle and sending information concerning the damage to a central computing unit, connected with the damaged vehicle, of an operator of the damaged vehicle by the damaged vehicle. Information concerning the damage of the vehicle is sent to a superior authority by the central computing unit. A further central computing unit of an operator of a self-driving further vehicle located near the damaged vehicle is informed about the damaged vehicle by the superior authority. When the further vehicle is moving towards the damaged vehicle, the further vehicle is put into a safeguarding mode by the further central computing unit.

A portable handheld traffic control device includes a lamp, a housing that encloses the lamp, and a handle. The handle attaches to a proximal (back) side of the housing and includes a control panel operable by a thumb of a hand grasping the handle. In a first (vehicle) mode, the lamp emits light on a distal (front) side of the housing in one of four colors: red, yellow, green, or white, when a respective button for the corresponding color is pressed. In a second (pedestrian) mode, pressing the red button causes the lamp to display a steady red upraised hand, pressing the yellow button causes the lamp to display a flashing red upraised hand, and pressing the green button causes the lamp to display a steady white walking person figure. A battery powers the lamp. The device includes a secondary display visible on the proximal (back) side of the device.
