摘要： In a navigation system using a bird's-eye view display mode, map data on a plan view map are subjected to a perspective projection conversion to obtain drawing data on a bird's-eye view map. In this case, an input of the position of a view point is accepted, and a projection plane for a bird's-eye view is determined on the basis of the coordinates of a current position and a destination and the position of the view point so that the display positions of the two points which have been subjected to perspective-projection conversion are coincident with predetermined positions. Alternatively, an input of a scale is accepted, and the position of the view point and the projection plane are determined on the basis of the coordinates of the two points and the scale so that the display positions of the two points after the perspective projection conversion are coincident with predetermined positions and the drawing scale is coincident with the input scale. Or, as a further alternative, an input of the projection angle is accepted, and the projection plane is determined on the basis of the projection angle and the position of the view point.

摘要： A receiver is applied to optical communication using an optical pulse signal carrying data which is cyclically updated. The optical signal is converted to a corresponding electrical pulse signal. The data is extracted from the electrical signal. The extracted data from successive cycles are compared. In response to the result of comparison between the data, a determination is made as to the number of cycles in which the extracted data is at a given value. When the determined number of cycles reaches a variable preset number, a previously used data value is replaced by the given value. The amplitudes of the electrical signal pulses are compared with a reference level. The preset number is varied in accordance with the result of comparison between the pulse amplitudes and the reference level.

摘要： A speech recognition system for an automotive vehicle including a voice detecting means such that: the start of the spoken instruction is detected on the basis of the start detection threshold level varying according to the voltage level of an inputted spoken instruction signal including noise within the passenger compartment; however, the end of spoken instruction is detected on the basis of the end detection threshold level which is equal to or higher than that determined in detecting the start. Therefore, even if noise rises abruptly after the start of spoken instruction has been detected with a time delay, it is possible to detect the end of spoken instruction reliably. The system comprises a holding circuit (22) for holding the start-detection threshold level or a threshold level corrector (37) for increasing the start-detection threshold level to an appropriate level, etc., in addition to the conventional voice detecting means.

摘要： A speech recognition system for an automotive vehicle which can record or recognize spoken instruction phrases reliably even when engine noise increases high within the passenger compartment. When the engine begins to operate, the gain of an amplifier of a speech input section or the threshold level of a voice detector is so switched as to reduce the sensitivity to spoken instructions. As a result, the driver must necessarily utter a spoken instruction in a louder voice and thus the proportion of noise level to spoken instruction signal level is reduced. The system according to the present invention comprises engine operation detecting means, an analog switch, two amplifiers or two multipliers, etc. in addition to the conventional speech recognizer.
