Abstract: An ultrasound system that detects a characteristic of an ultrasound wave. The system includes a circuit member defining a sensing portion operable to be exposed to the ultrasound wave. The system also includes a current generating device that generates a current in the sensing portion of the circuit member. Furthermore, the system includes a voltage sensor that detects a voltage across the sensing portion due to the exposure to the ultrasound wave to thereby detect the characteristic of the ultrasound wave.

Abstract: Therapy methods using pulsed cavitational ultrasound therapy can include the subprocesses of initiation, maintenance, therapy, and feedback of the histotripsy process, which involves the creation and maintenance of ensembles of microbubbles and the use of feedback in order to optimize the process based on observed spatial-temporal bubble cloud dynamics. The methods provide for the subdivision or erosion of tissue, liquification of tissue, and the enhanced delivery of therapeutic agents. Various feedback mechanisms allow variation of ultrasound parameters and provide control over the pulsed cavitational process, permitting the process to be tuned for a number of applications. Such applications can include specific tissue erosion, bulk tissue homogenization, and delivery of therapeutic agents across barriers.

Abstract: A therapy device for conducting rehabilitative exercises that includes a base having a receptacle. A standard is capable of being positioned in the receptacle in a substantially vertical position and has a plurality of adjustable arms slidably mounted on it. A locking mechanism is used to secure the standard in the vertical position. Each arm has means for being slidably mounted to the standard and a locking mechanism for fixing the arm at a height along the vertical, longitudinal axis of the standard. Each arm also includes a fastening means for removably securing occupational therapy exercise items, such as hooks, rings, and other items. The base of the therapy device include a slot for receiving the standard and may be shaped and sized to resemble an attache or brief case and to include a handle and one or more bins for holding occupational therapy exercise items. The bin may be compartmentalized and have a lid to secure exercise items therein.

Abstract: A purposeful exercise device including a frame; a pump mounted on the frame; and a work-adjusting mechanism movably borne by the frame and disposed in force-transmitting relation relative to the pump. The pump has a handle which is moveable along a path of travel from a first or fluid withdrawing position to a second or fluid exhausting position. The work-adjusting mechanism permits a patient or operator to selectively adjust the amount of work performed when moving the pump handle from the fluid withdrawing position to the fluid exhausting position or vice versa.

Abstract: A support for a basket during weaving is disclosed. The support has a frame made up of a first column and a second column. A basket mold is supported on the first column and a foam rubber pad is rotatably supported on the second column. A hydraulic cylinder has a piston rod attached to the foam pad. The pad holds a basket bottom, having warp and weave members nailed to the basket bottom, to the basket mold. The basket can than be woven, the top handle installed and the completed basket removed from the mold.
