A method for minimizing center frequency shift and linearity errors encountered in YIG filters, comprising the following steps: automatically generating data packages in test unit depending on the user request or containing all filter characteristic states and transmitting them to the driver circuit, adjusting the desired voltage level by means of the digital to analog converters contained in the structure of the data packages received by the driver circuit, and transmitting the adjusted voltage level to the YIG filter, measuring filter characteristics (scattering parameters) corresponding to the data packages transmitted to the YIG filter in the analyser, in order to calculate the center frequency shift of the filter, determining the center frequency and linearity calculations, and recording the characteristic features measured by the analyser in the test unit.

A waveform data acquisition module acquires the waveforms of electrical signals for multiple channels. A memory controller continuously writes a digital signal S3 to one from among a first memory unit and a second memory unit. When a given memory unit has become full, the memory controller notifies an external higher-level controller that the corresponding memory unit is full and switches the wiring target to the other memory unit.

A system for locating an optimal location of a reception antenna of the present disclosure has an unmanned aerial vehicle (UAV), a wireless internet service provider (WISP) tower configured for transmitting radio signals, and an antenna removeably coupled to the unmanned aerial vehicle, the antenna configured for receiving the radio signals. Further, the system has a processor that receives data indicative of a height from a user and automatically flies the UAV to the height. Additionally, the processor rotates the unmanned aerial vehicle at the height and detects the radio signals from the at least one WISP tower as the UAV rotates to determine an optimal azimuth, and if the radio signals received are not conducive for the provision of wireless services at the height, the processor moves the UAV to different heights and rotates the UAV until radio signals received are conducive for the provision of wireless services. Further, when the radio signals received are conducive for the provision of wireless services, the processor maneuvers the UAV downwardly toward the ground until the radio signals are no longer conducive for the provision of wireless services, thereby determining an optimal azimuth and location altitude range for a reception antenna.

A device for remotely supplying power, through magnetic induction, to a secondary module able to move in relation to a primary module along a predetermined path. An advantageous arrangement of the primary coils of the primary module and of a secondary coil of the secondary module furthermore allows the device to estimate the position of the secondary module. The primary coils are arranged such that: the primary coils form respective magnetic fields oriented in the same direction along their respective axes, during the movement, the inductive coupling between the first primary coil and the secondary coil evolves in the opposite way to the inductive coupling between the second primary coil and the secondary coil, the total inductive coupling existing between the primary coils and the secondary coil is substantially constant regardless of the position of the secondary coil.

A device provides an electromagnetically active area where the presence of a newly discovered field can manifest its characteristic behavior. This detection area is comprised of electrochemical batteries, rarified inert gases and materials combined so as to be responsive to electromagnetic field changes with remote data transmission for collection. The device creates an inertial reaction effect from the field by creating a high inertial mass. When the inertia of the core is at a high level, the device can also provide a progressive rotation and other physical changes in the device's location in space. Observation of the electro-magnetically active detection area, which surrounds the core as a spherical surface, will reveal the newly observed Machian phenomenon. The observation will occur with a frequency equal or greater than the actual surface area where the detection material is active.
