摘要： A method of communicating among wireless devices includes providing a frequency hopping schedule to a target device. The frequency hopping schedule includes a sequence of frequencies. The method also includes, at the target device, alternately sleeping and listening on a frequency in the sequence of frequencies according to the frequency hopping schedule, exchanging time base information between the target device and the transmitting device, at the transmitting device, using the time base information to determine a current frequency of the target device, from the transmitting device, and transmitting a packet of information uniquely addressed to the target device.

摘要： The present invention is directed to system and method for determining a fluid level. The system comprises a sensing rod assembly comprised of releasably connectable rod segments. Each rod segment carries a processor and a plurality of inductors. Each inductor generates a position signal responsive to a float signal. A float assembly comprises a housing containing a circuit having an integrally formed coil periodically energizable by a processor to emit the float signal. A control assembly receives the generated position signals and determines the fluid level. The method comprises providing releasably connectable rod segments with inductors that generate a position signal responsive to a float signal, determining a sensing rod assembly length, forming the sensing rod assembly, disposing it within a container, providing a float assembly periodically actuated to generate a float signal, generating position signals responsive to the float signal and analyzing those signals to determine the fluid level.
