An inflatable warning system for roads that enables the user to warn the rear driver by expanding an inflatable tube, which is a warning system. More specifically, when the driver pulls the handle of the gas injector formed on the main body, the compressed gas stored in a gas container is instantaneously injected to the inflatable tube, and the warning system expanded by the injected compressed gas stands up, thereby notifying the rear driver to recognize the warning system to prevent an accident.

An emergency signaling system is disclosed. The system includes a receptacle and a painting device. The painting device is covered in a paint material and stored in the receptacle. The receptacle can be used to launch the painting device onto a surface, such as a roof, in the event that a user needs to signal a search and rescue team or anyone near their present location. The painting device, upon contact with a surface, creates a painted signal. The painted signal can have different shapes according to the shape of the painting device. The painting device can include weight members or flexible frame members to facilitate opening the painting device from a closed or folded configuration to a fully open configuration once the painting device has been launched from the receptacle.

An expandable dock monitor and control system having a communicating pile light assembly. The communicating pile light assembly has an electrical system with a controller assembly. The communicating pile light assembly is mounted onto a pile at a dock. The expandable dock monitor and control system further has a gateway/controller system, a local interface device and at least one sentinel. The sentinel has transmitting circuitry to transmit specific event information to a nearest and/or respective communicating pile light assembly, which relays the transmitted specific event information to the gateway/controller system, which deciphers then notices the local interface device. The controller assembly has an RGB and white light controller section, an accelerometer/remote sensor inputs/relay outputs section, a transceiver/digital address tag section and a power supply section. The expandable dock monitor and control system additionally has a remote interface device and a remote access gateway.

A safety device coupled to a fluid end such that the safety device is in fluid communication with at least one of a suction chamber and a discharge chamber of the fluid end. The safety device has an outer housing and a visual indicator. The visual indicator is moveable between a first position where the visual indicator is retracted into the outer housing, and a second position where the visual indicator is extended out of the outer housing.
