Abstract: An impact cushioning material is provided for use in padded gloves for combat sports. The impact cushioning material comprises a first lattice and second lattice, each lattice configurable in structure to provide desired protection properties. The impact cushioning material allows for variable protection properties at different regions of the padded glove. The impact cushioning material can be used to provide all or the majority of the protection material within the glove, or in conjunction with other protective materials such as conventional foams. The impact cushioning material can also be configured as an insert, allowing for replacement and tailoring of use to a wider variety of conditions. The impact cushioning material can be manufactured from an elastomeric resin using conventional 3D printing properties, allowing for the varying properties of the material in a single component.

Abstract: An attachment for a projected head mounted display redirects images designed to be projected on retroreflective screens directly back into the eyes of a user. This permits, for example, the head mounted display to be switched from an augmented reality mode to a virtual reality mode. The attachment can be engaged or disengaged from the head mounted display. The attachment includes a freeform prism.

Abstract: A projected head mounted display system is disclosed that projects images onto a retroreflective screen, which are then reflected back for view by a user. The projected head mounted display system displays computer generated images at multiple focal distances to simulate a light field so as to match eye accommodation to vergence.

Abstract: A head mounted projection display includes a polarizing beam splitter stack that includes a waveplate. The polarizing beam splitter stack reduces optical losses and has a low forward extension. The polarizing beam splitter may be used at a 45 degree angle or at a non 45 degree angle relative to the line of view. A correction may be also be performed to the intensity of individual pixels to account for chromatic non-uniformity in the optical response of a retroreflector and other optical components.

Abstract: A protective sports glove worn by athletes during training or for use in a combative event to protect against injury and increase performance (including but not limited to total force generation, grip strength, striking force and speed, muscular endurance, time to contraction, etc.). These gloves are engineered with a dorsal splint system and a cooperating adjustable dual strapping wrist tie system to secure the gloves to the contour of the hands, to ensure they remain tight and fixed, and to support the wrist from excessive bending. The dual strapping system with the dorsal splint system provides increased wrist/hand rigidity mirroring a tightness of hand wrap bandages for maximal bone and tendon support of the hands and wrists, and this novel tie system increases the transfer of force generation to the point of impact.

Abstract: A system and method is presented to increase the sense of immersion in virtual and augmented reality systems by means of touch stimulation (haptic output) that is referred from the point of actual stimulation to the perceived point or points of contact with virtual objects and/or surfaces.

Abstract: A system of active fiducial markers for pose calculation of head mounted displays is described in which information is exchanged among said markers for the purpose of synchronization. Fiducial patterns are made more easily identifiable by selective duty cycles of sub groups of synchronized emitters and means is described to propagate pose information among markers.

Abstract: A protective headgear is disclosed. The headgear protects regions of the wearer's head including the crown, temples, and chin. The headgear has a closure system having two adjustable closures, operating substantially perpendicular to each other and to reinforce one another, that act to provide custom fit for the headgear and to maintain a field of view for the wearer during use and after repeated uses.

Abstract: A shin guard for combat sports is provided having increased protect for the wearer and the opponent. The shin guard has sleeve for surrounding the lower leg of the wearer and a front padding attached to the sleeve with a top portion reversibly secured which covers and hides a closure system. The shin guard may also have a calf reinforcement.

Abstract: In a head mounted virtual reality or augmented reality system, a fast but lower resolution second camera is added and used to quickly find an area of a visual field returned by a slower but higher resolution first camera, where that area is likely to contain the image of a marker for a head tracking system or a hand held device.

Abstract: A short pant has the following: a body having a plurality of fabric sections assembled together in a seamless manner having a front region, a back region, and opposing side regions forming a pelvic region, a pair of thigh regions, an inner surface, and an outer surface; and a closure system, operatively coupled to the body at the pelvic region at a top waist edge, for securing the short pant during wearing; and the pair of thigh regions each having a bottom edge and having a slit on each opposing side region substantially perpendicular to and extending from the bottom edge upward a distance toward the top waist edge. The short pant may be used for athletics, such as for combat sports training or competition. The short pant has a seamless body and side slits for minimal irritation, for providing a lightweight short pant, for minimal hook-and-loop in the closure while maintaining proper fit and allowing unrestricted movement.

Abstract: The present invention seeks to provide a user interface for use with a pair of gloves that controls at least one function of a device. The gloves are constructed and arranged to restrict the use of individual fingers of a wearer. The user interface comprises a sensor operatively configured to detect and transmit wearer input mediated through specific hand motions performed by the wearer. A processor is in operative communication with the sensor such that the processor is configured to receive, interpret, and process wearer input. Specific hand motions are detected by the sensor, transmitted to the processor, interpreted to correspond to at least one specific function of the device, and processed to execute the at least one specific function.

Abstract: The present invention provides a protective sports glove worn. The glove may be used by athletes during training or in a combative event requiring striking to protect against injury and increase performance, including, but not limited to, total force transference, grip strength, striking force and speed, muscular endurance, time to contraction, etc. These gloves have an adjustable dual strapping wrist tie system to secure the gloves to the contour of the hands and ensure they remain tight and fixed.
