摘要:
The present invention relates to the structural improvement of a wheel, and more particularly to an assembled wheel structure that has excellent resilience and no need to fill in air as well as is free of air leakage and easy to be disassembled. The present invention is constructed by a wheel body and a tire, wherein the wheel body is further constructed by a wheel shell and a matching wheel cover, while the tire, made of resilient materials (e.g., plastic, PU, etc.), inside accommodates a resilient inner tire to provide double-layered resiliency. There are several position pads on both sides of the inner circumference of the tire and the position pads 421, 431 on two sides are alternated with each other. A hole 422, 432 is formed on each position pad 421, 431 to allow the position rods to set in place and form a complete wheel structure.

The invention is based on speed changes of sound/ultrasound pulses and a fixed detecting depth between a transducer and sampling points to collect information of the detecting depth and/or a velocity of motionless and/or moving objects from the sampling points to construct two-dimension or three-dimension images of the sampling points. By taking advantages of a pulse ultrasound and a continuous ultrasound, a method of coded sound pulses can simultaneously collect the information of the detecting depth and the velocity from the sampling points, which improves imaging quality. Calculating a speed of the moving objects by simultaneously detecting time-of-flight (TOF) and TOF shift at same site from two separated piezoelectric (PZT) elements improves testing results with accuracy, simplification and reproducibility. An aliasing can be rectified based on the TOF and the TOF shift.

An adjustable airless tire with an air sac within a wheel includes an air sac located within a wheel to transfer a load of a vehicle from a ground contacting area of a tire to whole walls of the tire through a plurality of spoke structure of rods that connect with the walls of the air sac and the tire. A sensor detects a tension of the tire and a variation of a tension during driving. A control component adjusts the tension of the tire according the load of the vehicle and road conditions to improve its fuel efficiency, comfortability, controllability and safety. A rim of the wheel keeps an appropriate distance from the tire to limit the maximal level of upward movement of the rods. A transversely curved tire mounted to the rim of the wheel to form closed space between the tire and the wheel.

An adjustable airless tire system includes supporting rods connecting with walls of a tire and a metallic hawser loop, which transfer a load of a vehicle from a ground contact surface of the tire to whole walls of the tire. A sensor detects a tension of the tire and a variation of the tension during driving. A control component adjusts the tension of the tire according the load of the vehicle and the road conditions to improve its oil saving, comfortability, controllability and safety. A rim of a wheel keeps an appropriate distance from the tire to limit the maximal level of downward movement of the supporting rods, and support the load of the vehicle if the tire is overload or the supporting rods lose their function. A curved tire forms closed space between the tire and the rim of the wheel to prevent sticking of foreign objects between them.

This invention relates to flame-retardant modified maleic anhydride resins. This resin copolymer consists of styrene, maleic anhydride and, along with a halogen-free epoxy resin, interacts with a hydroxyl group to become a flame-retardant maleic anhydride copolymer that can be applied to copper clad laminate and prepreg. This composition comprises: (A) one or more epoxy resin mixtures; (B) modified styrene-maleic anhydride curing agent copolymer; (C) additives; (D) inorganic fillers. When the aggregate amount of components (A), (B) and (C) equals 100%, component (A), epoxy resin mixture, is 60%-80% in total weight, component (B), modified styrene-maleic anhydride curing agent copolymer, equals 10%-40% in total weight. This invention uses the copolymer of Styrene and Maleic anhydride to generate a flame-retardant hydroxyl group, and with the phosphorus additive, the above components eventually interact to form a flame-retardant modified maleic anhydride copolymer curing agent.

An adjusting apparatus includes a shaft, a rack, and a gear. The shaft includes a cam portion contacting a bracket and a securing portion. The cam portion includes a first outer edge and a second outer edge connected to the first outer edge. The cam portion defines a pivoting axis. The distance between the first outer edge and the pivoting axis is less than the distance between the second outer edge and the pivoting axis. The gear is toothed and secured to the shaft and the rack defines a plurality of slots engaged by the toothed gear. The rack is used to drive the gear and the shaft to be rotated.

A driving circuit of an organic light emitting device includes a switch module, a capacitor, and a driving unit. The switch module includes a first switch unit and a second switch unit. The first switch unit is coupled to a data line. The second switch unit is coupled to the organic light emitting device. During a programming period, the first switch unit is turned on and the second switch unit is turned off; and during an emission period, the first switch unit is turned off and the second switch unit is turned on. The capacitor is coupled to the first switch unit for being charged to a data voltage according to a data current of the data line during the programming period. The driving unit is used for generating a driving current to drive the organic light emitting device according to the data voltage during the emission period.

Data cells in a spreadsheet report are collapsed and expanded without disrupting other spreadsheet data. A user may want to drill down on data corresponding to a parent member of the report to display more detailed information about the parent member. Likewise, a user may want to drill up the displayed information corresponding to the parent member to hide detailed information associated with the parent member. Before expanding or collapsing a report, the spreadsheet is scanned for information to determine whether the display of other data in the spreadsheet would be disrupted by the expansion/collapse. The information may include cross-join information associated with the parent member, the number of child members associated with the parent member, the dimension of the report created by the parent member and the associated child members, and other reports that may be linked to the report that includes the parent member.
