Abstract: To accommodate computer graphics delays, the future position and orientation of a simulated vehicle are predicted in an operating sequence by separate coordinated models that are fed data signals indicating the operator's control actions. The control actions are extrapolated to provide further data signals. A suspension model and a nonlinear chassis model operate sequentially with a road model to provide one reference-state input to a prediction model. Other inputs to the prediction model are from the drive train and steering extrapolation units controlled by driver inputs.

Abstract: A photographic system designed to simultaneously take video and still portraits of a subject is disclosed. The system includes a video camera for real time display, on a cathode ray tube, of an image of the subject to be photographed. It also includes a still camera for taking a photograph of the subject. Each of the cameras normally includes a zoom feature, and apparatus is provided for interconnecting the zoom features so that the cameras zoom at the same rate. The two cameras are normally associated with or positioned in a toy animal so that the subject will be entertained during the photographic process and will not tend to be frightened or intimidated by a strange or unfamiliar camera apparatus.

Abstract: A recursive digital filter is disclosed for removing noise from an incoming television signal. The filter couples the incoming television signal to a subtracter without substantial attenuation of the television signal. The subtracter also receives at an input an attenuated difference signal comprising a selected amplitude of the difference between the incoming signal and an earlier received signal which has been delayed for an interval corresponding to one television frame. The subtracter subtracts the attenuated difference signal from the incoming signal and develops an output in which noise is substantially reduced.
