Systems and methods for virtual reality (VR) training of medical events are described herein. In one aspect, a method for generating a VR medical training environment can include displaying a medical event through a VR headset, receiving, from a user of the VR headset, a set of verbal responses corresponding to the user reacting to the medical event, determining a timestamp for at least one verbal response received from the user, determining a medical event score for the user based on the set of verbal responses and the timestamp, and displaying a summary of the medical event score via the VR headset or a display screen.

Systems for simulating joining operations, such as welding, are disclosed. In some examples, a system may use a desktop device for conducting welding simulations, such as for purposes of training In some examples, the system may additionally, or alternatively, use modular workpieces. In some examples, the system may additionally, or alternatively, conduct the welding simulation based on one or more selected pieces of welding equipment.

A virtual reality training system according to an aspect of the invention may include a floor system having a base of a particular length and width, an object member configured to be detachably installed on the floor system, an input unit configured to assign a first position, which corresponds to the position of an object within a virtual reality space having a length and width smaller than or equal to the length and width of the base of the floor system, and a mapping unit configured to compute and output a second position, for installing the object member on the floor system, computed as a position on the floor system corresponding to the first position within the virtual reality space.

A lightweight training aid is disclosed including selectively positioned posable appendages for use in various training exercises. The training aid may be formed of one or more separable and distinct portions including a head module, a torso module and a leg module, and combinations thereof. The head module and/or leg module may be releasably coupled to the torso module by interchangeable mounting arrangements. Appendages of the training aid may be posable, at least within a set range of motion, within any of a potentially infinite number of orientations. Methods of using such a training aid also are disclosed.

A method of training for welding through virtual reality (VR) provides a VR headset, a processing device, and a welding training tool. The processing device is communicably coupled with the VR headset and the hand-held welding training tool designed to simulate a real-world welding experience in VR. A virtual welding environment is displayed through the VR headset, and motion tracking input is received through the welding training tool. The user input is analyzed using an AI algorithm to evaluate user welding performance. User feedback devices such as sound and scent generation may be implemented in order to simulate a welding procedure. AI user feedback is implemented based on the welding performance to guide learning. Welding scenarios may be completed to train for welding in the virtual welding environment, and virtual currency may be awarded for gamification purposes. Multi-participant welding scenarios and immersive, objective-based, simulated real-world environments are further implemented.

The present application discloses and claims a kidney phantom consisting of a silicone rubber model featuring the anatomical shape of a human kidney, the renal artery, the renal vein, and a total of 11 tumors and 2 cysts. Each tumor is represented by a solid mass, while cysts are empty three-dimensional shapes. In order to accommodate the needs of both novice and advanced surgeons, tumors were designed with increasing surgical difficulty. The kidney phantom disclosed in the present application can be combined with a commercially available ensemble of laparoscopic tools to provide localized and remote training to surgeons and medical staff practicing laparoscopic and robotic partial nephrectomy.

A linear actuator is configured to be connected between a platform and a structure or ground for displacement of the platform relative to the structure or the ground. The actuator comprises a base, and an output displaceable linearly relative to the base. A first plurality of idlers are on the base, and a second plurality of idlers are on the output. An actuator unit has a reciprocating rotational output. A tensioning member has a first end connected to the rotational output of the actuator unit, and a second end connected to an anchor point on one of the output and the base, the tensioning member being routed from the rotational output, through the first plurality of idlers and the second plurality of idlers and to the anchor point for converting a winding/unwinding of the tensioning member into a translation of the output.
