Abstract: A method for transforming an audio signal and a system employing that method is disclosed. The method proceeds by extracting from the signal components that fall within a stop band, for example, using one or more low-pass filters. Then, a set of one or more harmonics of the extracted components is generated by down-sampling to create an intermediate signal, which is then repeated. Each harmonic is then weighted by controlling its gain by application to it of a respective weighting factor, the factors being determined by the psychoacoustic properties of a system that will reproduce the signal. Then, the weighted harmonics are added to the audio signal (which may have been subject to a delay to ensure synchronization) to create an output signal.

Abstract: The present invention proposes a system in which an ultrasonic carrier beam is modulated using an audio input signal. The audio signal is divided into frequency bands, and that frequencies in different ones of these bands are treated differently. Specifically, different modulating schemes are used for different frequency bands. Also, different transducer aperture sizes are used for different frequency signals. Also, a further frequency equalizer is provided within each of the frequency bands. Finally, a relatively smaller amplitude modulating index (or indices) is used for signals in low frequency band(s).

Abstract: A local positioning system is proposed for wirelessly locating an object using existing features within a static environment, such as walls, as the references for determining the position of the system. An antenna 16 attached to the object transmits RF signals which are reflected by the surroundings. During a training mode, the reflected signals are used to train a neural network 22, 43 to map the position of the object to the characteristics of the reflected signals. During a working mode, the trained neural network is to identify the position of the object based on reflected signals in working mode. Optionally, the reflected signals may be subject to a clustering process before input to the neural network.

Determination of the DOA of the signal may include receiving first and second UWB waveforms of the signal at one or more antennas of a UWB transceiver. A window may be defined in the first and second UWB waveforms such that the window is defined in a leading portion of the signal. First and second amplitude values of the respective first and second UWB waveforms in the window may be calculated. An amplitude ratio may be calculated with the first and second amplitude values and compared with calibration data to determine the DOA of the signal.

Abstract: A system and method for determining position of, for example, a robot based on reflected signals comprises a transmitter for transmitting signals in a number of directions within a range of directions and a receiver for receiving echoes of the signals from any direction in the range. The transmitter has a first rotatable antenna and the receiver has a second rotatable antenna which is mechanically couplable to the second antenna. The received echoes are processed by a processor to derive echo data signals indicative of the distance of the system to one or more reflective surfaces and the direction of the reflective surface(s) relative to the system. The processor is arranged to determine the position of the system relative to a starting position from the derived echo data signals indicative of the distance of the system to the reflective surface(s) and the direction of the reflective surface(s) relative to the system.
