  • Publication number: 20200404420
    Abstract: There is disclosed in one example an audio processor, including: an audio crossover to separate a first frequency band from a second frequency band, the first frequency band having a lower frequency band than the second frequency band; an excursion estimator to estimate from information of the first frequency band a predicted excursion of a low-frequency driver; an interpolator to interpolate an adjustment to the second frequency band to compensate for the estimated excursion; and circuitry to drive the adjusted second frequency to a receiver.

  • Patent number: 10070237
    Abstract: Speakers do not always operate linearly. Linearity of the speaker can affect the quality of the sound produced by the speaker, i.e., causing distortions in the sound, if the nonlinearites are not accounted for. To determine nonlinearities of the speaker, the speaker is often modeled and measurements are made to estimate the characteristics of the speaker based on the model. By using an angle sensor and a light source, a speaker manager can make a direct measurement of excursion or displacement of the speaker. Moreover, when the angle sensor, the light source, and the light beam are configured appropriately with respect to the moving cone of the speaker, the measurement can be substantially linear with respect to the amount of excursion or displacement. Such measurements are far simpler to use and in some cases more accurate than measurements made by other types of systems.

  • Patent number: 9383974
    Abstract: A computer program product and method for using a computer program product for graphically developing a computer program for execution at least in part on a separate host processor device, such as, a digital signal processor. The computer program product includes code for providing a graphical programming environment. The computer code which is used for developing the computer program includes a cell module for graphically representing a graphical control. The cell module does not contain any host processor specific code. The cell module may include code for rendering on the display of the computer that is operating as the programming environment one or more graphical controls. The cell module may also contain host processor independent code that accepts input from a user (parameter value) and converts the parameter value or applies an equation to the parameter value.

  • Patent number: 8701332
    Abstract: A lightweight decoy comprises a fabric sheet having a front portion with a digital image and a rear portion and is provided rigidity by a flat flexible perimeter band fastened generally to the perimeter of the fabric sheet. The perimeter band is capable of twisting and folding onto itself such that the decoy is collapsible into a reduced size for transport. By means of a plurality of straps, the decoy may be attached to a support such as a bow or tripod. A central opening through the fabric sheet is capable of receiving a firearm barrel, an arrow or a camera lens.
