An ultrasonic dog repeller with two ultrasonic emitters comprises a housing (1) formed with a part cavity, a front support (2) clamped in the part cavity, a main board (3) clamped on the front support (2) and provided with a battery (4), and an ultrasonic head clamped on the front support (2), provided with a pair of ultrasonic emitters (5) capable of emitting in-phase ultrasonic sounds, and electrically connected to the main board (3). According to the ultrasonic dog repeller with two ultrasonic emitters, ultrasonic waves emitted by the two ultrasonic emitters (5) are superimposed, so that compared with the prior art, the ultrasonic waves can be transmitted farther by users, and the two ultrasonic emitters (5) are protected from being burnt out.

A system and method for driving geese away from an area employs predetermined random illuminations of particular wavelength light directed in a fashion that repels geese while avoiding annoying humans. Embodiments include systems associated with golf course pins and other structures and animal decoys that hide undesired aesthetic appearances of prior art industrial lighting elements. Other embodiments employ adjustable/movable mirror elements used in conjunction with systems powered by solar energy panels positioned below the light source, which can be adjusted in terms of direction, shielding, color, duration, wavelength and pulsation, providing a variety of random patterns so as to avoid habituation by geese.

The invention discloses a method of operating a system for neurofeedback (NFB) that includes trained animal in a feedback chain. Feedback chain consists of the following steps:
A.fwdarw.B.fwdarw.C.fwdarw.D.fwdarw.A wherein said steps are: A. real time recording of the subject's EEG performed by the user module and forwarded to the mobile module; B. analytics of the recorded signal performed by the mobile module and algorithmic decisioning about the stimulation form; C. forwarding the stimulation towards the animal by using of one or more ultrasonic speakers simultaneously wherein the information needed for the animal performance is forwarded in the form of a coded ultrasonic signal; and D. performing of a learned action by the animal triggered by the received ultrasonic signal from the step C which provides a stimulus to the subject exposed to the NBF training.

A respiratory function testing system includes an air transforming device, a sound reception device and an operation device. The air transforming device is configured to collect exhaled and/or inhaled air for a predetermined period and generate a wide frequency range sound signal according to the collected respired air. The wide frequency range sound signal at least contains an ultrasonic signal. The sound reception device is configured to receive and record the wide frequency range sound signal as an audio file. The operation device is in communication with the sound reception device and is configured to receive and compute the audio file to generate a respiratory function parameter. Besides, the recorded wide frequency range sound signal may be converted into a spectrogram for further applications, and the computation of the audio file can be replaced by analyzing the spectrogram. A respiratory function testing method corresponding to the respiratory function testing system is also provided.
