  • Patent number: 9862312
    Abstract: A motion sickness countermeasure system for a user within a vehicle having a light array system configured to output visual stimuli presented in a field of view of the user; and a controller outputting a control signal to the light array system to activate the light array system in such a way as to mimic the visual input one would receive if one were to look outside the vehicle.
    Type: Grant

  • Patent number: 4791399
    Abstract: The amount of time required to produce a luminant output signal at the rear of a vehicle in response to the application of a brake is reduced by preheating the filament of the brake lamp and applying an overvoltage thereto when a brake switch is closed in response to the application of the brake. In accordance with the invention, preheating of the filament is achieved by switching a transistor in series with the filament at a fairly high frequency. The duty cycle of the switching operation can be adjusted to conduct a preheat signal through the lamp which results in little or no radiation of light from the filament. This corresponds to a filament temperature of approximately 2000.degree. K., and an increase in temperature of only approximately 800.degree.0 K., is required to produce a normal steady state rated illumination for the lamp.
