Abstract: The disclosed embodiments provide an apparatus and methods for assisting individuals in controlling respiratory rates. For example, a respiratory regulation apparatus is provided in the form of a plush animal toy that operates components to simulate the breathing rate of anxious individuals. The apparatus may include actuators that are controlled by a slotted cam that is dynamically rotated at varying speeds in a determined rotational direction. The actuators move inward and outward in relative directions to move a torso of the plush animal toy to simulate breathing. In certain aspects, actuators may expand outward while at the same time another actuator contracts inward to cause the torso to simulate realistic breathing movements. A processor controls the speed of the cam such that the simulated breathing of the animal toy apparatus can be reduced at a controlled rate to assist an individual in reducing their breathing rate to a calmer state.

Abstract: An optical pullback sensor assembly is disclosed that facilitates measuring displacement of a flexible elongate member, such as an ultrasound catheter probe that is inserted within a body. The disclosed embodiments of the optical pullback sensor assembly include a light source that illuminates a target surface that reflects at least a portion of light received from the light source. An optical sensor array including a set of sensor cells is arranged opposite the target surface to receive light reflected by the target surface. The optical sensor array is oriented to render image frames that are utilized to determine displacement of the flexible elongate member. A tracking guide on the pullback sensor assembly confines relative movement between the target surface and the optical sensor array in a direction of measured displacement of the optical sensor array. The measured displacement of the target surface in relation to the optical sensor represents displacement of the flexible elongate member.
