PORTABLE WIRELESS SENSOR SYSTEM
A removable device rests within a fixed device for the purpose of providing sensor data and/or communications capability to the fixed device. The removable device has no power source of its own, instead receiving power from a collar affixed to the fixed device with a pair of coils in proximate locations. Another pair of coils provides data between the two. The fixed device is permanently serialized so that a supervisory system may associate communications from the removable device with a certain fixed device.
1 . A wireless system gateway, comprising:
a removable WAND unit comprising a wireless communication device;
a collar for holding the WAND, wherein the WAND and the collar each have coils proximate to each other electronically coupled for providing power to the WAND and the exchange of data signals between the WAND and the collar.
