galvanic power transfer; eliminating conductivity problems commonly experienced with exposure to saltwater, oil spills, and extreme weather conditions. Removing any exposed metal contact within the charging system eliminates problems due to corrosion, oil, or mud. Tere are no metallic charging nodes that could be covered with mud or even erode away and direct water exposure will not short circuit the system, explains Einar Lende. Programmed routines perform specified tests
on both torch and charger in order to monitor systemic conditions. Automatic charging routines are performed at scheduled intervals to ensure optimal battery capacity, and to maintain long-term durability. An internal processor initiates these tasks on a regular basis when the torch is positioned in the charger unit, and produce feedback through a small LED indicator if any faults are detected. In order for optimal projection when using a high efficiency light emitting diode (LED) light source, a corresponding 4 degree lens was imbedded behind 3mm of scratch resistant hardened glass. Te lens produces a bright and uniform light, capable of lighting up objects at far distances. Te LED itself is solid with no inner filaments or fragile glass, and has a life span of more than 50 000 hours. Unlike a filament, which must gets intensely heated in order to emit light, the LEDs do not waste energy, and operate even below a single watt.
Wireless efficiency Te Reference solution has been based on wireless technology developed by the company Wireless Power and Communication (WPC) in Kristiansand, Norway. During the past nine years, induction technology has taken a great leap forward, both in terms of transfer efficiency while at the same time keeping heat exhaust to a minimum. “Our solution is capable of transmitting
hundreds of watts with a potential of 95 per cent efficiency rate. Te possibilities of application are therefore mostly limited to potential ideas and economic viability, says Geir Olav Gyland at WPC. WPCs improved and patented solution opens for a wide range of other industrial applications transferring not only power, but also video and data packages. Te technology allows transfer in a sealed system, offering a safer and more reliable solution for hazardous environments, whether the obstacles involve hydrous, highly erosive or potentially explosive areas. Industrial projects involving subsea cable connectors have already been developed based on WPC technology. l
