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： 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： Methods and apparatus for producing orientation dependent radiation, and orientation detection systems are disclosed. An orientation dependent radiation source directs radiation to an observation area and facilitates a determination of the orientation of the orientation dependent source from the observation area. In particular, the orientation dependent source produces a radiation pattern having one or more detectable centroids that vary in position across an observation surface of the orientation dependent source as observed from the observation area, based on a rotation of the orientation dependent source about one or more axes of rotation. According to various embodiments, the orientation dependent radiation source may include one or more primary radiation sources or secondary sources, such as reflectors. One or more orientation dependent sources may be employed in an orientation detection system according to the invention which includes a radiation sensor located in the observation area to detect the orientation dependent radiation pattern produced by one or more orientation dependent radiation sources. Additionally, the radiation pattern produced by an orientation dependent source may be visibly observable, allowing an observer to qualitatively determine the orientation of the source from the observation area.

摘要： A moving target which is reflecting waves will give rise to the well known Doppler frequency shift. When the reflected signal can be compared with the transmitted signal in homodyne detection, the resulting signal is called the Doppler signal. Both frequency and phase of the Doppler signal carry information about the motion of the target.By observing a Doppler signal at several points in space, it is possible to determine the position, velocity and acceleration of a moving target. Systems employing this principle are-used to track acoustic emitters with sonar, as well as radio emitters with radar. While the prior an has relied on analyzing the Doppler shift frequency, the present invention introduces a method employing the analysis of the phase of the Doppler signal. The phase-based algorithm shows a better signal to noise ratio in applications where the ratio of velocity and distance to the point of closest approach is large. The improved signal to noise ratio translates to lower power and lower cost for Doppler based three dimensional tracking.

摘要： Methods for controlling the net-displacement of a rotary fluid pressure device are disclosed. One of the net-displacement control methods (47) includes obtaining a desired input parameter (23) and a relative position (21) of a first member (43) and a second member (35) of a fluid displacement mechanism. A determination of a first and second output value is then made for each of a plurality of volume chambers (45) when the volume chambers (45) are supplied with fluid at fluid inlet and fluid outlet conditions, respectively. A total output value is then computed for each of a plurality of control valve configurations (63) and compared to the desired input parameter (23). The control valve configuration (63) with the total output value most similar to the desired input parameter (23) is then selected. A plurality of control valves (15) are then actuated in accordance with the selected control valve configuration (63).
