Latest Patents

One of Douglas's latest patents is titled "System and method for three-dimensional ultrasound imaging." This innovative ultrasound system is designed to produce a detailed representation of an object by utilizing a concave transducer array. The system transmits ultrasonic pulses into the object and receives the reflected pulses, which contain crucial structural information. Each transducer in the array generates output signals that represent portions of this information. The system also features a multi-focal lens structure for focusing the transmitted ultrasonic pulses and a multiplexing structure that couples output signals from transducers to construct a comprehensive representation of the object's structural information.

Another notable patent is "Ultrasonic linear or curvilinear transducer and connection technique therefore." This invention employs a double-sided flexible circuit to interconnect a piezoelectric ultrasonic transducer array. The ultrasonic crystal is equipped with first and second electrode layers separated by an insulation gap. The flexible circuit material is bonded to these layers, ensuring effective contact with the transducer electrodes. This design includes a concave acoustic lens with an acoustic velocity greater than water, enhancing the performance of the ultrasonic transducer.
