Abstract: A ski bike and conversion kit for converting a conventional bicycle to a ski bike include at least a rear ski assembly configured to replace a rear wheel of the bicycle. The rear ski assembly includes first and second ski mounts configured to receive corresponding first and second skis. The ski mounts are deployed on a frame that is configured to couple the ski mounts to the bicycle in place of the rear wheel. The frame and ski mounts are rotatably connected to one another and configured such that tilting the ski bike (e.g., to steer) causes the first and second ski mounts to tilt at corresponding angles that are greater than the tilt of the ski bike.

Abstract: A method for generating visual representations of interactions between two different materials is provided. The method can be performed using a computing device operated by a computer user or artist. The method includes modeling a primary material as a plurality of first particles and modeling a layer portion of a secondary material as a fluid volume. The secondary material can include a layer portion positioned between the plurality of first particles and an outer portion. At least one boundary condition might be assigned to a boundary positioned between the layer portion and the outer portion, the at least one boundary condition includes at least one pressure value. Values of motion parameters might be determined by applying the at least one boundary condition at the boundary and generating one or more visual representations of the primary material interacting with the secondary material based on the values of the motion parameters.

Abstract: A system for detecting and/or mitigating the effects of an obstruction on a surface of a sensor may include a surface configured to receive the sensor, and comprising a sensor window configured to provide a path through which the sensor senses the environment. The system may also include a vibratory actuator configured to facilitate vibration of the sensor window and a heating element configured to heat the sensor window. The system may further include an obstruction detection system configured to detect an obstruction, such as moisture, and an obstruction mitigation controller configured to initiate activation of the vibratory actuator and/or the heating element to mitigate the obstruction. The obstruction detection system may be configured to receive a signal from one or more sensors and detect the obstruction based at least in part on the signal.

Abstract: One embodiment of the present invention sets forth a technique for performing nested kernel execution within a parallel processing subsystem. The technique involves enabling a parent thread to launch a nested child grid on the parallel processing subsystem, and enabling the parent thread to perform a thread synchronization barrier on the child grid for proper execution semantics between the parent thread and the child grid. This technique advantageously enables the parallel processing subsystem to perform a richer set of programming constructs, such as conditionally executed and nested operations and externally defined library functions without the additional complexity of CPU involvement.

Abstract: A system for detachably coupling subassemblies of vehicles or other components is discussed herein. The system can include one or more driveshafts and worm drives to drive fasteners to couple the subassembly to the vehicle. The system can enable module repair or replacement in conventional locations without any additional infrastructure by driving fasteners horizontally into the body or other subassembly. In this manner, fasteners can be hidden and to utilize blind holes in the body of the vehicle. The system can be partially disassembled in situ to enable parts replacement and fastener access in the event of a failure. The system can be used in conjunction with a robotic cart to enable subassemblies to be removed from the vehicle for service and repair. A portion of the system can also act as a portion of, or to reinforce, the crash structure of the vehicle.

The system can include one or more driveshafts and worm drives to drive fasteners to couple the subassembly to the vehicle.
