摘要： A wireless communication system includes a wireless master node having a plurality of channels, and a number of wireless slave nodes having a plurality of the channels. The master node and the slave nodes are structured to wirelessly communicate over a particular channel. The master node and the slave nodes are structured to decide to hop to a different channel. The master node and the slave nodes are structured to select: (a) the different channel, in order to be as far away as possible from a number of the channels, which are known to cause interference to wireless communications between the master node and the slave nodes, or (b) the different channel, in order to be as close as possible to one of the channels of a different master node, which is compatible with the former master node, but without the different channel being employed by the different master node.

摘要： A system includes first and second wireless nodes having a clock with plural times, a wireless transceiver, and a processor cooperating with the transceiver to transmit and receive packets. The second node transceivers wirelessly communicate with the first or other second node transceivers. The second nodes include a Kalman filter with an output, plural filter gains, and an input representing the difference between: about the time of the clock when a received packet should have ideally been received, and a time when the received packet was actually received as measured by the clock. A circuit provides dynamic adjustment of the filter gains. The Kalman filter output estimates the difference between the time of the receiving node clock and a corresponding one of the times of the transmitting node clock. The second processor cooperates with the Kalman filter output to adjust the times of the receiving node clock.

摘要： An embedded system includes a first wireless node and a number of second wireless nodes, each of which includes a wireless transceiver, a memory storing a schedule defining transmission and reception of test packets, and a processor transmitting and receiving the test packets responsive to the schedule. The memories store a corresponding predetermined application employing some of the wireless communications, and a corresponding predetermined measurement function measuring wireless communication performance. A corresponding one of the schedules is executed by the corresponding predetermined measurement function. The second wireless nodes wait to receive a number of the test packets before being synchronized with their schedule and receiving and transmitting the test packets according to their schedule. The processors store data from the test packets to assess wireless communication performance between corresponding nodes.

摘要： A system for assessing wireless communication performance includes a first master wireless node and a number of second wireless nodes. A first schedule of the first node defines transmission and reception of a first set of test packets. A second schedule of the second nodes defines transmission and reception of a second set of the test packets. After start up, each of the second nodes is initialized, and waits to receive a number of the second set of test packets before being synchronized with the second schedule and beginning to receive and transmit the second set of test packets according to the second schedule. First and second processors store data from the first and second sets of test packets, respectively.

摘要： An apparatus for a power bus includes an inductive power harvesting unit structured to provide a first power output arising from current flowing in the power bus, an energy storage unit structured to store energy from the first power output and to provide a second power output, and a selector structured to select one of the first and second power outputs and to provide a third power output from the selected one. A processor is powered from the third power output of the selector. The selector is further structured to normally provide the third power output from the first power output of the inductive power harvesting unit. The processor is structured to determine that the first power output of the inductive power harvesting unit is inadequate and to cause the selector to provide the third power output from the second power output of the energy storage unit.
