Abstract: An ultrasonic surgical instrument assembly including an irrigation sleeve assembly defining a lumen and an ultrasonic tip at least partially disposed within the lumen of the irrigation sleeve. The irrigation sleeve assembly may comprise a hub and an irrigation sleeve coupled to the hub. The irrigation sleeve may comprise an inner sheath and an outer sheath, both extending distally from the hub. The outer sheath may surround at least a portion of the inner sheath to define an irrigation passageway between the outer sheath and the inner sheath configured to deliver irrigation fluid to the surgical site. The distal end of the inner sheath may extend beyond the distal end of the outer sheath. Each of the inner and the outer sheath may be coupled to the hub by an annular sealing member configured to create fluid-tight seal between the hub and the respective inner and outer sheath.

Abstract: The present disclosure relates to an ultrasonic surgical handpiece assembly comprising a surgical handpiece for use with an irrigation sleeve and ultrasonic tip. The surgical handpiece may comprise a piezoelectric transducer disposed within a housing and configured to manipulate the ultrasonic tip. One or more lumens and/or a flex circuit including an antenna may be disposed within the surgical handpiece housing. The lumen(s) may be configured to provide irrigation and/or aspiration to the irrigation sleeve and/or ultrasonic tip. The irrigation sleeve may comprise a second antenna configured to communicate with the ultrasonic handpiece antenna. The irrigation sleeve may further comprise and an alignment and/or coupling feature configured to removably secure the irrigation sleeve to the housing and orient the second antenna relative to the ultrasonic handpiece antenna. The irrigation sleeve may further comprise a lumen for supplying irrigation and/or aspiration to the ultrasonic tip.

Abstract: A lens barrel attached to an imaging device, including a focus lens unit that is movable in an optical axis direction; an actuator that moves the focus lens unit along the optical axis direction; a drive control section that controls drive of the actuator; and a setting section that is capable of setting a movement range of the focus lens unit to be one of a first range and a second range that differ from each other with respect to at least one of one end and another end, each range defining the range in which the focus lens unit is allowed to move. Even when the movement range of the focus lens unit is set by the setting section to be one of the first range and the second range, the drive control section removes the setting of the movement range when instructions are received from the imaging device.

Abstract: An audio data synthesizing apparatus includes an imaging unit that captures an image of a subject through the use of an optical system and outputs image data, an audio data acquiring unit that acquires audio data, an audio data separating unit that separates first audio data produced by the subject and second audio data other than the first audio data from the audio data, and an audio data synthesizing unit that synthesizes the first audio data and the second audio data of which gains and phases are controlled for each channel of the audio data to be output to a multi-speaker on the basis of the gain and a phase adjustment amount set for each channel.

Abstract: The lens barrel has a first lens unit that is disposed at the object side and changeable between a first state, a spacing of the lenses is a predetermined spacing, and a second state, the spacing of the lenses is narrower than in the first state; a second lens unit that is disposed at the image side and capable of changing a focusing state by moving along the optical axis; a restricting member that restricts the change of the first lens unit from the first state to the second state; and driving unit that, in a state in which the change to the second state is restricted by the restricting member, moves the second lens unit toward the image side, wherein the restricting member releases the restriction in association with a completion of the movement of the second lens unit by the driving means.
