An adjustable airless tire system with changeable supporting structures optimizes the contradictory relationship between a suspension potential and a tension of a tire according to changes of road conditions. The changeable supporting structures can be selected from one of three separated and compatible parts, including metallic rods, or springs or spring-loaded shock absorbers according to customer's requirements and usage of a vehicle. A metallic cable is used to maximize the suspension potential of the tire and a control component is used to regulate the tension of the tire. A curved tire forms a closed space between the tire and a rim to prevent foreign objects from sticking between them. Therefore, the invention possesses advantages of oil efficiency, affordability, comfortability, controllability and safety.
摘要:
An adjustable airless tire system uses springs, a metallic hawser loop and a control component to regulate a tension and a size of the ground contact surface of the tire, which optimizes contradictory relationship between hardness and suspension of the tire according to changes of road conditions. An enhanced rim of a wheel to protect the springs and provide limited moving ability for the vehicle if the airless system loses their functions; and a curved tire to form a closed space between the tire and the rim to prevent foreign objects from sticking between them. Therefore the invention improves oil efficiency, affordable, comfortability, controllability and safety.
摘要:
During transmission, a speed of sound pulses gradually reduces due to acoustic impedance. Regulating a length or a density or a sound speed of the sound pulses affects their average speed in the transmitting medium, sound intensity and detecting depth. Time of flight (TOF) and TOF shift can be used to calculate the depth and moving speed of detecting objects. Calculating a speed of moving objects by simultaneously detecting TOF shift at same site from two separated piezoelectric (PZT) elements improves the testing results with accuracy, simplification and reproducibility. Coding sound pulses to obtained the TOF and the TOF shift will simultaneously calculate the depth and the moving speed of sampling points, which can be used to construct 2D and 3D images for these motionless and/or moving sampling points. Coded sound pulses also improves the quality of the imaging.

A dynamic and flexible architecture and methods for demodulation of high data-rate streams with high symbol-rates, such as in satellite communications systems or computer network communications systems, is provided. A data stream of a data transmission is received, the data stream corresponding to a plurality of data symbols. A plurality of data samples corresponding to each of the data symbols is generated. Further, one or more representative data samples, corresponding each of the data symbols, are generated based at least in part on timing control signals and the generated data samples for the respective data symbol. The generated data samples corresponding to each of the data symbols other than the representative data samples are dropped. The timing control signals are then adjusted based at least in part on the generated representative data samples.
摘要:
During transmission, a speed of ultrasound pulses gradually reduces due to acoustic impedance. A length and a density and a sound speed of the ultrasound pulses decide their average speed in the transmitting medium, frequencies, sound intensity and detecting depth. Time of flight (TOF) and TOF shift can be used to calculate the depth and moving speed of detecting objects. Calculating a speed of moving objects by simultaneously detecting TOFs at one detecting site from two separated piezoelectric (PZT) elements improves the testing results with accuracy, simplification and reproducibility. Coding ultrasound pulses to obtained the TOF and the TOF shift can be used to simultaneously calculate the depth and the moving speed of the objects, which also avoids a problem of an aliasing for highly moving speed of the objects. Coding ultrasound pulses also improves the quality of the imaging.
