    摘要: A vibrorotational fluid flow actuator includes: a first vibrorotational component comprising a first body including an axis, a plurality of first legs extending from a bottom surface of first body in a direction of and at an angle to the axis, and a plurality of first blades extending from a respective side of the first body in a direction perpendicular to the axis, wherein when the first vibrorotational component is placed on a chassis, vibration of the chassis induces rotation of the body such that the blades and body rotate about the axis of the body thereby inducing fluid flow in a fluid surrounding the actuator.

    摘要: A system and apparatus for navigating and tracking a robotic platform includes a non-contact velocity sensor module set positioned on the robotic platform for measuring a velocity of the robotic platform relative to a target surface. The non-contact velocity sensor module set may include a coherent light source that is emitted towards the target surface and reflected back to the coherent light source. Measuring the change in intensity of the reflected coherent light source may be used to determine the velocity of the robotic platform based on the its relationship with the principles of a Doppler frequency shift. A communication unit may also be utilized to transmit data collected from the non-contact velocity sensor set to a computer for data processing. A computer is then provided on the robotic platform to process data collected from the non-contact velocity sensor set. A user may then monitor the determined trajectory path of the robotic platform and transmit navigation instructions to the robotic platform based on the received trajectory path data.

    摘要: Systems and methods are provided for tunable band pass filtering for Tunable RF Anti-Jamming Systems. A tunable notch filter includes a transmission line coupled to an antenna, a splitter, a band-stop filter, a polarity inverter, and a combiner. In operation, the band-stop filter suppresses predetermined frequency bands of a received signal creating a filtered signal, the polarity inverter creates an inverted signal, and the combiner combines the filtered and inverted signals to create a pass band including the predetermined frequency bands and suppressing frequency bands adjacent the predetermined frequency bands. Alternatively, a tunable multiband bandpass filter includes first and second bandpass filters and a plurality of tunable passive components adapted to tune the first and second bandpass filters to first and second frequency bands, thereby creating a multiband pass band signal including the first and second frequency bands and attenuating frequency bands adjacent to the first and second frequency bands.
