Wireless Recharge
We have the “Wireless Recharge” system operating for our “Non Radiated Field” Data Links. This is not a particularly radical technology, but this demonstrated ability to use the Transmit/Receive Transducer Coils of this Data Link system to charge the batteries at each node, as well as verify all the calibrations and operating parameters at each isolated node, is a significant milestone.
We intend to cluster propulsion modules to form a variety of customized “Deep Space” experimental systems. Our Google Lunar Lander system will probably use use a cluster of seven modules (each having a fuel tank, motor and relevant control systems). Customized systems for interplanetary experiments may have as many as 50 modules. The wireless links will allow such assemblies with no cable harness or connectors. (This can also allow the modules to be assembled on orbit with simple techniques.) Modules can also be selected, replaced and even reprogrammed – with opening - at any time during vehicle integration.
The ability to conduct recharge, test and calibration without opening any of the modules makes preparation for launch much easier – even if it occurs many months after module production and at a far distant launch site.
Our prototype system accomplishes recharge at moderate distance even with our low power Transmitter prototype. In addition to battery recharge – to accommodate battery “self discharge” - this mode will also be used with appropriate Data Codes to switch the modules from “Zero Power” mode to standby.
In the standby mode, microamps of current will keep a more sensitive detector in operation. For a preset number of days after standby activation, the Link Nodes will be ready to respond to a much weaker signal – generated from the other Link Nodes in the vehicle – to switch them into full operation, with microcontroller data handling at each node and the potential to operate motors, release mechanisms, valves and sensors.
