Abstract: A digital signal generation assumes that a base frequency (the frequency with which the primitive phase angles are specified relative to) is equal to the carrier frequency for all relevant times. But this causes errors in the digital signals output to each array element transducer. Thus, it is necessary for the development of a signal generation system that is capable of producing a digital signal using the free selection of amplitude and phase. This is used to produce a substantially error-free signal that preserves the amplitude and phase relative to a constant base frequency while allowing the carrier frequency to vary.

Abstract: Reducing the maximum output of transducers near boundaries is described. In further refinements, the distribution of the transducer's maximum amplitude is determined by analyzing the Fourier dual of band-limited functions. This enables the Gibbs phenomena, or side lobes, to be effectively mitigated. Further, apodization is used to adjust transducer amplitudes, which in the context of emitting phased arrays, yields output with specific side lobe structure. A modification to the general principles of the method of apodization that are capable of working around transducer limitation will be described. Further, a shared horn structure modifies the distribution of acoustic power over emission angle from a group of transducers.

Abstract: A method for specifying desired quantities of the energy flux of the combined waves of acoustic radiation pressure to apply producing a mid-air haptic pushing force, which has the effect of simultaneously reducing the harmonic distortion present is described. Further, a method for communicating only the summaries of acoustic field contributions at the required locations in the form of summed portions of the relatively small matrix whose row and column count depend only on the control point count is described. Further, phased arrays of ultrasonic speakers can produce a relatively large amount of acoustic energy which is usually directed in a specific direction or focused to a particular point depending on the application of the array. Further, to allow the system to be driven more strongly than usual, the complex-valued linear system that governs the drive signal to each control point is solved twice.

Abstract: A method of generating complex exponentiation and logarithms in hardware is described that uses half the number of bits of lookup tables as the state-of-the-art. By splitting up each of the iterations into more simplified stages or using more iterations, the amount of precomputed information that must be held by the circuitry is reduced. This allows synthesis tools to take this more succinct logical description of the algorithm and make it into efficient gate level logic for fabrication into more compact integrated circuitry.

Abstract: An alternate root tree or graph structure for ray and path tracing enables dynamic instancing build time decisions to split any number of geometry acceleration structures in a manner that is developer transparent, nearly memory storage neutral, and traversal efficient. The resulting traversals only need to partially traverse the acceleration structure, which improves efficiency. One example use reduces the number of false positive instance acceleration structure to geometry acceleration structure transitions for many spatially separated instances of the same geometry.

Abstract: An indoor location is mapped into a grid comprising grid cells, each cell associated with items or objects detected as being present in the corresponding cell. The grid, grid cells, and linked items and/or objects are generated and updated using an Augmented Reality (AR) algorithm that maps a physical environment into cells and measures distances and directions within the environment relative to each cell. Walking paths (routes) to the items within the indoor location are generated using the grid information. As a user walks a path, the user's position within the indoor location is mapped and tracked to the cells and the path revised based on the user's actual position. A user device provides video via an AR application to track the user's position; a rendering of the position and path are superimposed within the video being viewed by the user on the user-operated device.

Abstract: A system providing various improved calibration techniques for haptic feedback is described. An acoustic field is defined by one or more control points in a space within which the acoustic field may exist. Each control point is assigned an amplitude value equating to a desired amplitude of the acoustic field at the control point. Because complete control of space is not possible, controlling the acoustic field at given points yields erroneous local maxima in the acoustic field levels at other related positions. In relation to mid-air haptic feedback, these can interfere in interactions with the space by creating secondary effects and ghost phenomena that can be felt outside the interaction area. The level and nature of the secondary maxima in the acoustic field is determined by how the space is controlled. By arranging the transducer elements in different ways, unwanted effects on the acoustic field can be limited and controlled.

Abstract: Creating near-instantaneous effects in a phased-array system may occur by splitting the update process of the array state into parts that depend on different update rates. Alternatively, leveraging the uncertainty of physical properties of focusing in a phased-array system may improve the intersection between the body part and the control point. Specifically, by focusing behind or in front of the intended region or at a position with a calculated geometric relationship to the intended interaction region, a larger volume (region) of space is addressed that more certainly contains the body part participating in the interaction. This larger volume is then subjected to the ultrasonic radiative energy flux that encodes the properties desired for the interaction point, which may include haptic and/or audio points.

Abstract: An acoustic field may be produced from a transducer array having known relative positions and orientations In this acoustic field, one or more control points may be defined. An amplitude may be assigned to the control point. Mid-air haptic effect for a virtual object on a human body part may be generated by moving the control point in a single closed curve comprising a plurality of curve segments. The single closed curve traverses at least one location where the human body part intersects with the virtual object. Additionally, a user may interact with virtual three-dimensional content using the user's hands while a tracking system monitoring the user's hands, a physics engine updates the properties of the virtual three-dimensional content and a haptic feedback system provides haptic information to the user.
