Typically, there are three buoyant smoke signals carried in each liferaft. These signals are used to alert nearby vessels or aircraft of an emergency situation.
"Liferaft" is one word. It refers to a type of inflatable raft designed for emergency situations at sea, providing flotation and safety for individuals. In general usage, compound words like "liferaft" are often combined into a single term.

The purpose of track light in rail signalling system is to control railway traffic safely, essentially to prevent trains from colliding. Being guided by the fixed rails, trains are susceptible to collision and they cannot stop quickly, for this reason the track lights signalling system is very important to avoid any kind of accident.
According to SOLAS (Safety of Life at Sea) regulations, a liferaft must be equipped with pyrotechnics, specifically a distress signal rocket and a hand flare. These pyrotechnic devices serve to signal for help and indicate the liferaft's location in emergency situations. The liferaft should also include a means to safely ignite and deploy these signals. The exact requirements may vary based on the type of vessel and its area of operation.
Cellular Signalling was created in 1989.
The population of Thales Rail Signalling Solutions is 2,000.
Each liferaft is typically equipped with a minimum of two handheld distress flares. However, the exact number can vary depending on the specific regulations and requirements of the vessel or the maritime authority in the region. It's important for operators to check the safety equipment guidelines relevant to their situation.
Boyd's Automatic tide signalling apparatus was created in 1906.

I think so. The CO2 cartridge could also be used for propulsion
