Abstract: A phacoemulsification handpiece for ocular surgery includes a housing including a grip for holding the phacoemulsification handpiece, a needle extending from the housing for removing ocular material from an eye, and a horn connected with the needle. The phacoemulsification handpiece also includes a driving circuit configured to vibrate the horn according to a multi-harmonic driving signal, to generate non-sinusoidal ultrasonic motion of a tip of the needle.

Abstract: The disclosure provides infant swaddling device or system in the form of two sleeves to help dampen the moro reflex—one for each arm—with the option of a non-flexible backing (or splint) and weighting. This device safely mimics the swaddling effect by adequately reducing the moro (twitching) reflex and flailing of arms, thus helping baby sleep for longer periods of time. The infant swaddle device may eliminate or reduce the risk of suffocation or overheating that other swaddle transition suits, garments, methods, or devices pose. This device can be used as a swaddle alternative; in conjunction of a swaddle blanket or sack, pod, etc. or without; or as a transition device to easily wean infants from the swaddle.
