Driving Techniques for Phased-Array Systems - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240265907 titled 'Driving Techniques for Phased-Array Systems
- Simplified Explanation:**
The patent application describes various techniques for driving phased array systems, specifically focusing on acoustic phased arrays for applications such as mid-air haptics, parametric audio, acoustic levitation, and acoustic imaging.
- Key Features and Innovation:**
- Mitigating the effects of changes in the air to provide a consistent haptic experience - Producing trap points in the air - Defining phased-array optimization in terms of vectors for more consistent haptic effects - Defining control points or regions in space via a controlled acoustic field - Using a reduced representation method for constructing acoustic basis functions - Efficient evaluation of complex-valued functions for a large quantity of throughput - Generating a krylov sub-space of a matrix - Maximizing an objective described by different control points and/or regions for creating the acoustic basis functions
- Potential Applications:**

Original Abstract Submitted
various techniques for driving phased array systems are described, specifically intended for acoustic phased arrays with applications to mid-air haptics, parametric audio, acoustic levitation and acoustic imaging, including a system: 1) that is capable of mitigating the effect of the changes in the air to provide a consistent haptic experience; 2) that produces trap points in air; 3) that defines phased-array optimization in terms of vectors for the production of more consistent haptic effects; 4) that defines one or more control points or regions in space via a controlled acoustic field; 5) that uses a reduced representation method for the construction of acoustic basis functions; 6) that performs efficient evaluation of complex-valued functions for a large quantity of throughput; 7) that generates a krylov sub-space of a matrix; and 8) that maximizes an objective described by different control points and/or regions to those used to create the acoustic basis functions.
