Abstract: Described herein are various embodiments of differential air pressure systems and methods of using and calibration such systems for individuals with impaired mobility. The differential air pressure systems may include an access assist device configured to help a mobility impaired user to stand in a pressure chamber configured to apply a positive pressure on a portion of the user's body in the sealed pressure chamber. The system may also include load sensors configured to measure the user's weight exerted inside and outside the chamber. The system may be calibrated by determining a relationship between the actual weight of the user and the pressure in the chamber, where the actual weight of the user may be measured by more than one load sensor and at least one load sensor is not in the pressure chamber.

Abstract: Systems, methods, and non-transitory computer-readable media can identify a virtual character being presented to a user within a real-time immersive environment. A first animation to be applied to the virtual character is determined. A nonverbal communication animation to be applied to the virtual character simultaneously with the first animation is determined. The virtual character is animated in real-time based on the first animation and the nonverbal communication animation.

Abstract: A display system comprising a steerable display having a monocular field of view of at least 1 degree, positioned within a scannable field of view of at least 20 degrees, the steerable display positioned for a user. In one embodiment, the steerable display is positioned for the user's fovea.

Abstract: A vertical takeoff and landing (VTOL) aircraft is configured with a front set of propellers mounted to a front wing and an aft set of propellers mounted to an aft wing wherein the propellers may be repositioned by rotating them around a front thrust vectoring axis and an aft thrust vectoring axis respectively. The positioning of the propellers with respect to the thrust vectoring axes and the positioning of the thrust vectoring axes with respect to the upper and lower limits of the passenger compartment ensure that, as the propellers are rotated from a vertical thrust position to a horizontal thrust position, the plane of rotation of the propellers never intersects with the portion of the passenger compartment where a failure of propeller components could result in debris penetrating the passenger compartment and causing injury.

Abstract: In one aspect, an electronic gaming system is provided. The electronic gaming system may cause to be displayed on a display device a game interface including a matrix having a plurality of symbol positions for displaying a symbol within each symbol position, generate, based on an RNG call outcome, an optimal game outcome, programmatically select a suboptimal game outcome based on the generated optimal game outcome, display at least a portion of the suboptimal game outcome in the matrix, cause to be displayed a prompt to select from a plurality of user options to modify at least one symbol of the at least a portion of the suboptimal game outcome displayed in the matrix, modify, based on a selection received from a user of one of the plurality of user options, the symbols displayed in the matrix, and determine if the optimal game outcome is displayed.
