Abstract: An ultrasound simulation method for rendering an ultrasound image of an anatomy model, comprises acquiring, with at least one model sensor, a position and/or orientation of the model; acquiring, with at least one probe replicate sensor, a position and/or orientation of an ultrasound imaging probe replicate, the ultrasound imaging probe replicate interacting with low friction with at least one anatomy model surface, the model surface being deformed by the pressure of the ultrasound imaging probe replicate; aligning a VR/AR model to the tracked position and orientation of the anatomy model and the ultrasound imaging probe replicate; interpolating a 2D ultrasound slice by sampling through a standard reconstructed 3D ultrasound volume, as a function of the tracked position and orientation of the anatomy model and the ultrasound imaging probe replicate.

Abstract: A retractable pet leash assembly includes a housing, a spool, a leash and a braking assembly. The spool is disposed inside the housing and biased by a spring and includes braking notches. The leash is wound about the spool. The braking assembly includes a pawl, a pawl spring and an operating member. The pawl selectively engages the braking notches, the pawl spring biases the pawl towards engagement with the spool. The operating member moves the pawl between first and second positions to move the pawl into and out of the path of the braking notches. The operating member has a pawl non-engaged position in which the pawl is in the first position, a first pawl engaged position in which the pawl is in the second position, and a second pawl engaged position in which the operating member is retained while the pawl is in the second position.

Abstract: A retractable leash system includes a housing, a leash, a spool, and a brake. The spool is attached to the leash and disposed within the housing. The leash is configured to be rotationally biased so as to urge the leash into a spooled configuration. The brake includes an operating button, a compression spring, and a brake member coupled to the operating button. The brake member is associated with the compression spring and is configured to engage the spool by operation of the operating button, such that, when the brake is engaged, the spool is prevented from rotating in an unspooling direction and capable of rotating in a spooling direction.

Abstract: Anatomy mannequins, models and medical simulation systems described herein may facilitate various medical procedure training by rendering a realistic passive haptic touch when the end user manipulates the anatomy model with a handheld tool. An anatomy tissue model may comprise at least one fabric layer arranged over at least one foam layer to replicate the low-friction, elasticity and hardness of a living body anatomy tissue, such as the vagina wall, without requiring the use of lubricant in the medical simulation training procedure. The anatomy tissue model may be attached as an insert to a body structure model. A diversity of anatomy tissue models may be adapted with different fabric layer and/or foam layer designs, each design corresponding to a different haptic touch, so they can be interchanged in a medical training simulator system to realistically replicate different medical training scenarios.

Abstract: A two or more subject retractable leash, and methods of use thereof, is disclosed, which includes a roll-back feature on each retractable leash. The leashes may be locked in place by engaging a single lever. The leashes retract regardless of whether the spools are locked or unlocked. Each leash retracts independently of the other leashes, such that a dual leash may be used to walk one subject. In some embodiments, a single subject retractable leash includes a roll-back feature that provides and allows for leash retraction, whether or not a brake associated with a spool thereof is engaged.

Abstract: Embodiments of flexible ultrasound simulation devices, methods, and systems described herein may facilitate various medical procedure training by rendering realistic ultrasound images in accordance with the end user interaction with an anatomy model, an ultrasound probe replica and a medical tool. An ultrasound probe replica may be adapted with a low friction tip, such as a roller ball. A data processing unit may compute and display an accurate Virtual Reality/Augmented Reality (VR/AR) model and an ultrasound image in accordance with the position and orientation tracking of the VR/AR ultrasound simulator elements. The VR/AR ultrasound simulator may be adapted to realistically render the VR/AR model and the ultrasound image as a function of the user interaction with the VR/AR simulator elements.

Abstract: Simulation systems and methods may enable medical training. A manufacturing unit may receive data from a configuration unit indicating identification and manufacturing parameters for an anatomy model. A data processing unit may receive data from the configuration unit identifying the anatomy model, and data from a calibration unit indicating a position and/or orientation of a position and orientation sensor relative to the anatomy model. The data processing unit may also receive data from the position and orientation sensor indicating a position and/or orientation of the anatomy model. The data processing unit may generate a virtual image using the data from the position and orientation sensor, the data from the calibration unit, and the data from the configuration unit. The data processing unit may render the virtual image to a display.
