  • Patent number: 10680669
    Abstract: A frequency discriminator is described. The frequency discriminator comprises a power splitter (2) for splitting a signal into a plurality of paths (40, 41, 42, . . . , 4n). At least two of the plurality of paths (41, 42, . . . , 4n) include respective filters (121; 122, . . . , 12n) having different frequency characteristics which are configured to provide respective filtered signals to respective power detectors (161, 162, . . . , 16n. The frequency discriminator comprises an analogue-to-digital conversion section (8) which is configured to receive values of measured powers from the power detectors, to generate digital values of measured powers and to provide the digital values of measured powers to a digital processing section (10). The digital processing section is configured to estimate a value (11) of at least one frequency in the signal in dependence on the digital values, for example the ratio of the digital values, of measured powers and on frequency responses (201, 202, . . . , 20n; FIG.

  • Patent number: 10629172
    Abstract: A drum beater including a hollow housing and loose fill material to generate a rattle sound upon striking a drum is disclosed herein. A user can customize the sound and loudness of the generated rattle or sound by changing the size, shape, quantity, materials, or combinations thereof of the hollow housing. The user can further customize the sound and loudness that they wish to create by also changing the size, shape, material, amounts or combinations thereof of the loose fill material. The drum beater also includes a rod to mount the drum beater to a drum foot pedal to control the drum beater while playing the drums. Optionally, the drum beater includes a pad mounted thereon, which changes the way the rattle sounds. The user, such as a musician, is free to express their creativity by how much can be varied in order to generate different sounds and rattles.

  • Patent number: 10571544
    Abstract: A method of determining incident angles of Radio Frequency, RF, signals received by an antenna array comprising a plurality of antennae is described. The method comprises generating a plurality of direction finding, DF, signals based on antenna signals received from the antenna array, wherein each DF signal corresponds to a respective antenna array element and each antenna array element corresponds to one or more antennae. A plurality of DF spectra are then generated, each DF spectrum corresponding to a respective DF signal and comprising measured values of signal power at two or more given respective frequencies. An incident signal angle is calculated for each given frequency, based on the measured values of power at the frequency, the configuration of the antennae in the antenna array and antenna gain patterns corresponding to the antenna array elements.
