Abstract
Contents of one or more received messages can be analyzed to determine whether a transceiver device generating the inductive field has already been programmed with a unique communication code. If not, bidirectional communications can be established to program the transceiver device with a unique communication code over an inductive link. Orientation or position of a transceiver device can be used to initiate a process for programming a communication code. Generally, the communication code can define a unique relationship between two or more transceiver devices.

32. A method of supporting inductive communications among multiple transceivers, the method comprising:
-
sharing a wireless bandwidth to support bidirectional communications between pairs selected from at least three transceivers, a transceiver pair being assigned use of one or more time slots to communicate within a communication cycle;
disposing at least two transducer elements in at least one transceiver to support communications between the transceivers at any angular orientation relative to each other within a range of distance;
for each pair of transceivers communicating with each other, comparing link qualities of communications between different transmit-receive transducer element pairs of communicating transceivers; and
selecting transmit-receive pairs of transducer elements to support further communications in respective time slots between pairs of transceivers based on detected link quality. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
