Abstract: Embodiments described herein relate generally to systems and methods for creating durable lubricious surfaces (DLS) via interfacial modification. The DLS can be prepared via a combination of a solid, a liquid, and an additive that modifies the interface between the DLS and a contact liquid, resulting in an interfacial layer that acts as a lubricant and/or protective coating between the DLS and the contact liquid. The lubricating effect created between the additive and the contact liquid results in enhanced slipperiness, as well as the protective properties that can help with durability of the DLS.

Abstract: A system may have one or more processors and a memory storing instructions, that when executed by the processors, cause the processors to perform operations that include receiving data associated with a user, and determining that the received data corresponds to a direction of movement by the user through a virtual reality (VR) environment, augmented reality (AR) environment, or mixed reality (MR) environment. The operations may also include transmitting a tile of high quality image data to a display device based on the direction of movement by the user, transmitting a command to the display device to display one or more aspects of a region of the VR environment, the AR environment, or the MR environment based on the tile of high quality image data, and preloading one or more additional tiles of high quality image data into a preloader based on the tile of high quality image data.

Abstract: A vehicle transaxle comprising a plurality of mounting flanges fixedly mountable to an axle tube of the vehicle absent any additional structure for mounting the transaxle to the vehicle. The axle tube houses a wheel axle to which the transaxle is operably couplable. The transaxle additionally comprises a transaxle mounting collar that is fixedly mounted to or integrally formed with a housing of the transaxle. The mounting collar is structured and operable to have a prime mover of the vehicle mounted thereto and to support the weight/mass of the prime mover such that the prime mover is mountable to the vehicle via only the mounting collar absent any additional structure for mounting the prime mover to the vehicle such that the prime mover can be cantilevered from (e.g., suspended from) the transaxle, e.g., the prime mover is ‘free floating’.
