摘要： A system and method for using a microscope to at least haptically observe a specimen in a fluid is provided. In one embodiment of the present invention, an audio frequency modulation sensing (AFMS) device is used to convert an optical signal from the specimen into an electrical signal. A haptic feedback device is then used to convert the electrical signal in at least vibrations, thereby providing a user with haptic feedback associated with the optical signal from the specimen. In another embodiment, a second electrical signal can be provided to a second haptic feedback (e.g., shaker, piezo electric, electric current inducing, etc.) device in the fluid, thereby allowing for bidirectional haptic feedback between the user and the specimen. In other embodiments, aural data can be extracted from the electrical signal and presented to the user either alone in in synchronization with video data (e.g., from a video camera).

摘要： Embodiments of a dermatological cosmetic treatment and/or imaging system and method can include use of transducer to create a linear thermal treatment zone at a focal depth to form a band shaped treatment area. The system can include one or more ultrasound transducers, a cylindrical transduction element, an imaging element, a hand wand, a removable transducer module, a control module, and/or graphical user interface. In some embodiments, a coated transducer may be used to provide more consistent treatment in cosmetic procedures, including brow lifts, fat reduction, sweat reduction, and treatment of the décolletage. Skin tightening, lifting and amelioration of wrinkles and stretch marks are provided. Treatment may include heating of tissue for a duration to deactivate a percentage of cells in the treatment region.

摘要： The present invention relates to an ultra-thin acoustic lens for subwavelength focusing in a megasonic range and a design method thereof. More particularly, the present invention relates to a super-oscillatory planar ultra-thin acoustic lens for subwavelength focusing in the megasonic range, which includes a plurality of concentric regions arranged in a concentric shape with reference to the center point, wherein the concentric regions include a plurality acoustic insulation region for insulating incident acoustic waves, and a plurality of transmission regions for transmitting acoustic waves, the acoustic insulation regions and the transmission regions being formed alternatively in a radial direction from the center point so as to focus incident acoustic wave energy onto a subwavelength region. The acoustic lens has flat surfaces on both sides thereof respectively and has a plate shape having a constant thickness, and a layout, which is a radius of each of the plurality of acoustic insulation regions and transmission regions in the concentric region, is determined by a topology optimization reverse design method.

摘要： In order to obtain a predetermined ultrasonic wave field in a homogeneous internal part of a medium masked by an aberrating barrier, an ultrasonic lens is interposed between the emitting ultrasonic probe and the aberrating barrier. The ultrasonic lens is calculated by using a model of the medium comprising a mapping of ultrasonic wave propagation properties obtained from actual imaging of the medium such that when the ultrasound probe sends a predetermined ultrasonic wave, said predetermined wave generates the predetermined objective ultrasonic wave field in the medium.

摘要： A waveguide assembly for guiding sound includes a chassis that provides a cavity configured to receive sound propagating in a forwards direction along a primary axis of the waveguide assembly; a fixed waveguide that is fixed with respect to the chassis and positioned on the primary axis of the waveguide assembly, wherein the fixed waveguide is spaced apart from the chassis and is configured to guide sound received by the cavity through at least one opening formed between the fixed waveguide element and the chassis; a moveable waveguide that is moveable with respect to the chassis between: a standby position in which the moveable waveguide is configured to obstruct the at least one opening and form a forward-facing surface of the waveguide assembly; an operational position in which the moveable waveguide is configured to allow sound to exit the cavity through the at least one opening.
