    摘要: An automatic vehicle following system is provided for controlling a following vehicle to maintain at least a predetermined distance behind a preceding vehicle and to substantially follow the path of the preceding vehicle. An on-line measurement system of the preceding vehicle generates signals indicative of the velocity (having speed and directional components) of the preceding vehicle, and a communication system transmits the velocity signals to the following vehicle. The following vehicle likewise has a communication system for receiving the signals from the preceding vehicle, and an on-line measurement system for providing signals indicative of the velocity of the following vehicle and signals indicative of the distance between the two vehicles. A signal processing system of the following vehicle is coupled to the communication system and on-line measurement system for estimating motion trajectory of the preceding vehicle based on the difference in the velocities of the preceding and following vehicles and the following distance. A control system generates control signals and takes action so as to perform speed control and maintain at least a predetermined safe following distance between the two vehicles, and steering control to substantially follow the path of the preceding vehicle.

    摘要: In an apparatus and method for automatic vehicle following, a pair of video cameras are mounted on the front portion of a following vehicle, and each camera generates image data indicative of a respective image of a distinctive mark located on a rearward portion of a lead vehicle. An image processor generates two one-dimensional image-intensity distributions for each mark image based on the image data, and in turn generates a respective edge-intensity distribution based on each image-intensity distribution. The edge-intensity distributions are each generated by taking the first derivative of the respective image-intensity distribution. The image processor in turn generates a respective feature vector based on each edge-intensity distribution, wherein the vector components of each feature vector define select characteristics of the respective mark image. The center points of the two corresponding mark images are determined based on the feature vectors, and a signal processor generates signals indicative of the following distance and the heading angle of the lead vehicle based on the image center points. A window enclosing each mark image is moved upon generating a new mark image to the approximate center point of the preceding image, to substantially follow image movements from one camera image frame to the next, and thereby suppress noise and enhance the image-processing speed of the apparatus.

    摘要: An automated object following system includes a tracker associated with a following device, and a guider associated with an object to be followed. The tracker includes a first processor, and at least two transducers for generating an encoded ultrasonic signal. Each transducer has a control input communicating with the first processor for emitting an encoded ultrasonic signal generally toward the guider in response to a command signal from the first processor. The encoded ultrasonic signals carry signal source identification information. A radio frequency (RF) receiver communicates with the first processor for receiving from the guider an encoded RF signal carrying distance and direction information of the guider relative to the tracker to be used for steering the following device toward the object to be followed.

    摘要: There is disclosed a direct fuel cell comprising an anode and a cathode immersed in an electrolyte in the presence of a reductant and oxidant. Specifically, the fuel cell lacks a permselective membrane or other chemical barrier between the anode and cathode. Instead, the fuel cell has a mechanical/electrical porous separator that permits the free diffusion of liquid between all elements of the fuel cell. The fuel cell further contains an anode electrode of conductive substrate with catalyst and a cathode comprising a hydrophobic coated material that prevents cathode flooding. As a result, oxidation of the anode fuel and reduction of the cathode fuel occur to a substantial extent only at the anode and cathode, respectively, and is capable for ambient pressure/temperature and passive operation.
