Abstract: Systems and methods are provided for mitigating motion sickness. When motion sickness is predicted, the motion sickness mitigation system alters vehicle performance, cabin conditions, and/or alerts the occupant to upcoming vehicle actions, to avoid or alleviate motion sickness. A controller includes a processor that receives an occupant profile and traffic information for an upcoming trip of the vehicle on a route. Using the occupant profile and the traffic information, the processor calculates whether the occupant will experience motion sickness when the vehicle travels on the route. A vehicle performance signal correlated to the calculation, is delivered by the processor to initiate motion sickness mitigation. The vehicle performance signal varies operation of a steering actuator, an acceleration actuator, and/or a brake actuator to implement the motion sickness mitigation.

Abstract: A lifting mechanism includes a load bearing structure, and a carrier. The carrier is configured for supporting a load. The carrier is moveable relative to the load bearing structure in a substantially vertical direction relative to a ground surface, along a vertical axis. A load carrying spring applies a spring force that biases the carrier relative to the load bearing structure in a direction along the vertical axis. A negative stiffness device interconnects the carrier and the load bearing structure. The negative stiffness device applies a device force that biases the carrier relative to the load bearing structure in a direction along the vertical axis. The device force opposes the spring force. The device force includes a magnitude that is substantially equal to the spring force in any of a plurality of different positions of the carrier relative to the load bearing structure along the vertical axis.

Abstract: A system and method for estimating road grip conditions. More particular, the invention relates to a system and method for computationally estimating a road condition of a road location using tire-road grip data received from at least one or a plurality of vehicles and transmitting this road condition via a network such that users may anticipate upcoming road conditions.
