  • Publication number: 20220373416
    Abstract: A system and method for measuring resistance over an array. The array includes at least three electrodes. Nodes at each intersection between input electrodes and output electrodes have variable resistance. A driving voltage is applied to a selected input electrode and an output current is received at a selected output electrode. A selected node is at the intersection of the two selected electrodes and includes an electrical component with a resistive property. Remaining electrodes are connected with a ground for isolating the selected node from the effects of changes in impedance of the remaining nodes. The driving voltage is converted to an output current by resistance at the selected node. The output current is converted to an output voltage with a current-to-voltage converter circuit for measuring the resistance of the electrical component. The nodes may be measured as the selected node in sequential or non-sequential patterns.

  • Patent number: 11463804
    Abstract: A loudspeaker system with viscoelastic material affixed between two flexible panels is disclosed. The loudspeaker system dissipates the energy of motion, resulting in less pronounced resonant peaks. The effect may be especially evident at high frequencies, where energy is dissipated over many cycles in a shorter period of time. Also disclosed are the method of making the loudspeaker system and a method of using the loudspeaker system.

  • Publication number: 20220286777
    Abstract: Systems and methods of driving plate loudspeakers with different parameters based on frequency region in a way similar to typical cone driver crossover networks are described. These systems and methods may be implemented using arrays of independently controlled drivers which allow a designer to emphasize or de-emphasize certain modes in certain frequency bands. Tuning the characteristics of the plate's motion can also affect the acoustical properties in a larger space rather than just at a single location. The systems and methods described herein can grant a designer a degree of control over the characteristics and performance of the plate.
