Abstract: Control consoles and methods for supplying a drive signal to a surgical tool are provided. The control console comprises a transformer with primary and secondary windings. The primary winding receives an input signal from a power source and induces the drive signal in the secondary winding to supply the drive signal to the surgical tool. A first current source comprising a leakage control winding is coupled to a path of the drive signal. The primary winding induces a first cancellation current in the leakage control winding to inject into the path of the drive signal to cancel leakage current. A sensor coupled to the path of the drive signal outputs a sensed signal to provide feedback related to leakage current. The sensor may connect to a second leakage current cancellation source and/or a fault detection stage. The power source may be variable and may also energize the second current source.

Abstract: Improved systems and methods for diagnosing an injury of a patient. The system and methods provide for more accurate scans of the injury thereby enabling a combat medic, a medical technician, or even untrained individuals to quickly diagnose the injury. By providing more accurate information, the systems and methods provide the technician with additional information regarding treatment options, such as whether to transport the patient or treat the patient in place, potential for aspiration, and other information about dangerous fluid build-up such as size, depth, and types of surrounding tissues, thereby increasing survivability of the patient. The systems and methods can also provide a diagnosis of the injury as well as suggestions on actions to take to treat the patient.

Abstract: Examples herein include piezoelectric layers of an ultrasound transducer, ultrasound transducers, methods of manufacturing the transducers, and methods of manufacturing the piezoelectric layers of an ultrasound transducer. In one example, a piezoelectric layer of an ultrasound transducer include a non-metallic frame and a piezoelectric material. The non-metallic frame surrounds the piezoelectric material on at least two sides and is coupled to a lens support structure with a structure such that an acoustic lens and the piezoelectric material are oriented substantially parallel to each other. The piezoelectric material is sized to span an area greater than or equal to an active surface of the acoustic lens.
