Abstract: Devices for providing an acoustic wave to a target location include at least one transducer device and at least one beam-forming processor to cause the at least one transducer device to produce a first acoustic wave, the first acoustic wave includes a plurality of pulses having a pulse repetition frequency, where a pulse width of each pulse is in a range of 10 ns to 10 ?s and the pulse repetition frequency is in a range of 1 Hz to 50 Hz, receive data associated with a second acoustic wave, wherein the second acoustic wave is a reflection of the first acoustic wave, determine a characteristic of the second acoustic wave, and determine whether to change a beam path of an acoustic wave produced by the at least one transducer device based on the characteristic of the second acoustic wave. Methods and computer program products are also disclosed.

Abstract: A method for directing ultrasound energy toward an organ of a subject, including: determining a location of the organ within the subject's body; and directing ultrasound energy at the location of the organ within the subject's body using a wearable ultrasound device.

Abstract: An apparatus for sterilization of objects or materials comprises an enclosure for containing a gaseous atmosphere; an acoustically transparent platform located within the enclosure for supporting the objects or materials to be sterilized; one or more non-contact ultrasound transducers positioned within the enclosure and spaced from the platform; and an electric power amplifier for exciting the one or more transducers.
