Techniques and systems are described for providing modularity, tracking and simulation features of a mixed reality simulator. A modular approach to tracking systems, tracked instruments, and interchangeable modular physical models is described. Enhanced indicators and indicator interfaces improve imaging probe and instrument orientation and alignment with respect to a physical target, including but not necessarily within a combined physical and virtual system; these include anisotropy indicators, indicators of alignment in both in-plane and out-of-plane ultrasound or other imaging techniques, and perpendicularity indicators for better placement of probes and instruments over curved surfaces. A universal needle hub is described that integrates tracking system components and simulation feedback components usably with varying needle types.

A pet management system and associated methods are configured for assisting an at least one user in caring for and training an at least one actual pet. In at least one embodiment, a central computing system is configured for receiving and processing data related to the at least one user and associated at least one actual pet. An at least one user device is under the control of the at least one user and in selective communication with the computing system. The system is configured for first teaching the at least one user how to care for and train an at least one virtual pet, configured for simulating the qualities and behaviors of the associated at least one actual pet, so as to better ensure that the user is sufficiently prepared for and capable of subsequently caring for and training the corresponding at least one actual pet, for which the system also assists in an ongoing manner.

A simulated non-lethal weapon comprises a cartridge that is fitted with an acoustic triggering mechanism. By detecting, capturing, and processing the sound of an electrical arc, the cartridge can activate a laser emitter. The laser emitter triggers a simulated laser “bullet” light and the laser light can be used to provide feedback about the shot placement for the simulated firearm in a laser-based simulation and training environment. In this fashion, more effective and efficient training with simulated non-lethal weapons can be conducted.

A system, including a memory in communication with a processor, the memory storing instructions that when executed by the processor cause the processor to create and store a geospatial virtual environment comprising a plurality of entities each having one or more location attributes and corresponding time attributes wherein at least one of the plurality of entities is a virtual asset and wherein at least one of the plurality of entities represents a real vehicle having a defined location within a physical space having spatial coordinates that are mapped to the virtual environment, receive an updated location of the real vehicle, map the received location of the real vehicle to the geospatial virtual environment, update the entity of the geospatial virtual environment corresponding to the real vehicle with the mapped received location and output data comprising a portion of the geospatial virtual environment to a display device adapted to display to an operator of the real vehicle a mixed reality representation of at least one virtual entity.

A light-diffusing optical element with efficient coupling to light sources with high numerical aperture. The light-diffusing optical element includes a higher index core surrounded by a lower index cladding. The cladding includes scattering centers that scatter evanescent light entering the cladding from the core. The scattered light exits the element to provide broad-area illumination along the element. Scattering centers include dopants, nanoparticles and/or internal voids. The core may also include scattering centers. The core is glass and the cladding may be glass or a polymer. The element features high numerical aperture and high scattering efficiency.
