摘要： A navigation system which can enhance the position determining accuracy of a mobile object without employing any high precision measuring instrument. The navigation system comprises a GPS range measuring device (101 in Fig. 1), an angular velocity measuring device (102), a velocity measuring device (103) and an azimuth measuring device (104), which measure the motion of the mobile object; a GPS range error estimating device (105), an angular velocity error estimating device (106), a velocity, error estimating device (107) and an azimuth error estimating device (108), which estimate errors involved in the respectively corresponding measuring devices; and a position calculating device (109) which calculates the position of the mobile object from the outputs of the error estimating devices. The error estimating devices are implemented by Kalman filters and averaging processes. The factors of the errors of the individual measuring devices are assumed, and the outputs thereof are corrected, so that the position of the mobile object can always be determined at a high accuracy without employing any high precision sensor.

摘要： The invention relates to an engine startup fuel control system for use with an internal combustion engine (20) of the type having a plurality of combustion chambers (30), an air intake passage (34) fluidly connected to each combustion chamber (30) and a source of fuel (44). The system includes a multipoint fuel injector (42) associated with each combustion chamber (30) in which the multipoint fuel injector (42) has an inlet connected to the fuel source (44) and an outlet fluidly connected to the intake air passageway (34) adjacent its associated combustion chamber (30). A cold start fuel injector (60) also has an inlet (62) connected to the fuel source (44) and an outlet (64) connected through a cold start passageway (68) with each combustion chamber (30). A processing circuit (48) selectively activates the multipoint fuel injectors (42) as well as the cold start fuel injector (60). The processing circuit (48) determines the air/fuel mixture introduced by the cold start fuel injector (60) into each combustion chamber (30) during engine startup and then selectively activates the multipoint fuel injectors (42) to achieve a predetermined air/fuel mixture in each combustion chamber (30) during engine startup. The processing circuit (48) also variably retards the ignition of the combustion charge within at least one of the combustion chambers (30) to achieve faster heating of a catalytic converter. Furthermore, the cold start fuel injector (60) is optionally activated in a plurality of spaced sub-pulses (112) for each combustion charge provided to each combustion chamber (30).

摘要： The invention relates to a system which detects droplets (12) on a translucent surface (14) having a camera (16) which, upon activation, acquires an image of a portion of the surface (14). A radiation source (22), upon activation, illuminates the portion of the translucent surface (14) while a control circuit selectively activates both the camera (16) and the radiation source(22). A processor receives a captured image from the camera (16) and, through image processing, generates an output signal representative of the number of droplets (12) on the portion of the translucent surface (14).

摘要： The invention relates to a throttle position sensor (40) for a throttle having a movable throttle element (24). The sensor (40) includes an elongated electrically resistive strip (12) having a first (14) and second (16) end. The first end (14) of the strip is connected to a first voltage potential while the second end (16) is electrically connected to a second voltage potential different from the first end (14). An electrically conductive wiper (20) is in sliding contact with the resistive strip (12). The wiper (20) and resistive strip (12) are relative to each other and one of the wiper (20) or resistive strip (12) is connected to the movable throttle element (24). Consequently, the position of the wiper (20) relative to the strip (12) varies proportionally with the position of the throttle element (24) so that a voltage output from the wiper (20) varies proportionally with the position of the movable throttle element (24). A circuit is associated with the sensor (40) which determines the contact resistance between the wiper (20) and the strip (12).

摘要： A method and a system are disclosed for identifying a gas type. The system includes a first sensor in contact with the gas and which produces a first electrical output signal indicative of a first condition of the gas. Similarly, a second sensor is also in contact with the gas and produces a second electrical output signal indicative of a second condition of the gas. A processor receives the output signals as input signals from the first and second sensors and determines the type of gas by calculation or from lookup tables stored in memory accessible to the processor. The first and second conditions of the gas are selected from the group of temperature, mass flow rate, temperature and pressure.
