Custom alerts may be generated based on sound type indicators determined using a machine learning classification model trained on user-provided sound recordings and user-defined sound type indicators. A device may provide a sound recording and a type indicator identifying an entity that made a sound in the recording for storage in a database that includes a plurality sound recordings associated with a plurality of type indicators. A machine learning classification model may be trained based on the stored recordings, including the user-defined recordings. The model may be used to classify sounds recorded by other devices and generate alerts identifying the type of sound. Thus, multiple users may contribute data to customize machine learning models that recognize sounds and generate alerts based on user-defined identifiers.

A distress signal system for a sea vessel comprises several navigation lights (11, 12, 13, 14, 15), which are connected in an electrical circuit and arranged to emit a steady light in different directions in a normal operating state. The distress signal system comprises a control means (28, 30) connected to the electrical circuit which in a distress signal state is arranged to vary the current to the navigation lights (11, 12, 13, 14, 15) in order to vary the light emission therefrom in accordance with a distress signal, such as SOS. A manually actuatable actuator (24) is connected to the control means (28, 30) to activate or deactivate the distress signal state. A light activating means (26) is arranged to provide a varied power supply to the navigation lights (11, 12, 13, 14, 15) in connection with activating the distress state, regardless of whether these are in operating state or not. Such a distress signal system can be provided by connecting a separate distress signal unit comprising a control means to the navigation lights of a sea vessel.

A lighting assembly is configured to create an emergency notification. The lighting assembly has a housing with a housing first surface and a housing second surface. A plurality of strobe lights and/or light emitting diodes (LEDs) is arranged into at least one row and at least four columns. A direct current power system is joined to the plurality of lights and further comprising a printed circuit board electrically coupled to radio frequency relay switch, and a battery. A wireless remote is communicatively coupled to the radio frequency relay switch. Activating the wireless remote directs the printed circuit board to provide power to the plurality of lights creating the emergency notification.

An inflatable RADAR signal device that is capable of rising above the surface of the water when deployed and that reflects RADAR emissions. The signal device is a self-contained, small, independent system that can withstand being present in a maritime environment, including being submerged in the water and/or being located on a vessel in the water, for an extended amount of time. The device includes a housing that houses one or more deflated balloons that are constructed of a material that, when inflated, rise above the level of the water and that reflect RADAR emissions. The device includes at least one gas cylinder for inflating the balloon(s), and a mechanism to trigger release of the balloon(s) from the housing including a mechanism to trigger release of the gas from the gas cylinder(s) to inflate the balloon(s).

A smart traffic control device implements a method for detecting faulty sensors that result in false green requests and/or undetected true green requests. The faulty sensors may include inductive loops and pedestrian pushbuttons. The traffic control device may communicate with remote resources, including computer systems connected to human resources, to help identify the faulty sensors. The human resources may be crowdsourced. The traffic control device's communications with the remote resources may go through vehicle computers and smart phones of vehicles' occupants and pedestrians. The traffic control device may emit signals to enable vehicle computers to improve accuracy of position location. The traffic control device may emit its state (e.g., Green/Yellow/Red in various directions) and time to state changes, in real or substantially real time. A vehicle computer may receive the state and/or time to state changes and vary operation of the vehicle's power train in response thereto.

A mobile emergency light device includes a casing (1), a moving closure cover (2), a translucent lens (3), an electronic circuit board (5) for control, and a combined reflector (4), in which the combined reflector (4) has an inverted bell shape and is open at both ends, in which the electronic circuit board is securely connected to the combined reflector (4), and provided with a plurality of light-emitting diodes (LED), suitably angled towards the combined reflector (4), and in which the casing (1) forms inside this a cylindrical cavity (13), whose interior houses an automatic switch, driven by the base of the casing approaching a ferromagnetic material.

A location detector kit having a pouch with a cartridge containing a gas and the cartridge having a gas-release-activator, when the cartridge releases the gas through a gas straw on the cartridge, a rip cord is pulled from the outside of the pouch to release the gas, a deflated balloon then connects to the gas straw of the cartridge, when the balloon is inflated and rises above the pouch, the gas-release-activator breaks to allow the balloon to be fully deployed above the pouch, the cartridge is secured to the cable, and rises with the cable as the balloon rises and pulls the cable upward.

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.
