Salus, as this device is called, is a mountaineering safety tool for that will deliver concise communication between parties of climbers or individuals. Colored lights will function as basic commands that will be able to create a conversation, where each unit sports a quartet of buttons – red, amber and green which represent commands and an acknowledgment button. Whenever you press a colored button, it will send a signal over to a connected device that illuminates its colored light. The climber will be able to “reply” by pressing acknowledge after that.
Targeting mountaineering and multi pitch climbing use, there are also other areas of life where Salus could be of use. Made out of PVC toughened plastic for roughness and durability, the lamp itself is made from solid Perspex that has been sandblasted to soften the light. Anyone willing to see this idea materialize into the real world?
