An electrical wheelchair includes a vertical rotating shaft connected fixedly to a seat member and journalled on a frame of a chair body, and a worm unit for transferring rotation of a motor shaft to the rotating shaft. A wheel-controlling switch is disposed on the seat member, and is operable to rotate a driving wheel unit. A rotation-controlling switch is also disposed on the seat member, and is operable to rotate the rotating shaft and the seat member by any desired angle smaller than and equal to 360°. When the seat member rotates from a frontward position by 180°, the rotational direction of the driving wheel unit is reversed under automatic control. As such, forward and rearward movement of the wheelchair can be conducted with ease.

The present invention discloses an exfoliative clay and a derivative thereof and a method for producing the same. The exfoliative clay is formed by emulsion exfoliating an inorganic layered silicate clay with an amphibious intercalating agent by powerfully stirring at 60–180° C. and not less than 14.7 psig. The amphibious intercalating agent is obtained by copolymerizing polyoxyalkylene amine having molecular weight over 1,800 and polypropylene-grafting-maleic anhydride (PP-g-MA). Before emulsion exfoliation, the intercalating agent is acidified with an inorganic acid. The acidification is the key step for obtaining nanoscale of emulsifying particles less than 100 nm for the exfoliation. The exfoliative clay can be further extracted with a hydroxide or a chloride of alkali metal or alkaline-earth metal to obtain a derivative in the form of nanosilica plates which is free of organic portions.

The invention relates to novel pathogenic OrfF and OrfF′ polypeptides derived from Xanthomonas campestris pv. campstris, the nucleic acid molecules encoding the polypeptides and the uses of the same for detecting or preventing a black-rot disease of a crucifer plant, making organic fertilizer or composting and being a biofilter for degradation of organic compounds.
摘要:
A system for measuring periodic displacement of an object in periodic motion at a first frequency includes a light source module, a camera module and a processor. The light source module is configured to periodically illuminate the object at a second frequency that is different from the first frequency and that is related to a sum of the first frequency and a first constant. The camera module is configured to take pictures of the object. The processor is in communication with the camera module in order to receive the pictures, and is configured to determine periodic displacement of the object based on the pictures.

An electric vehicle assembly includes an electric vehicle and a processing device. The electric vehicle includes a wheel, and an electric motor configured to drive the wheel to rotate and to output a value of torque force applied on the wheel and a speed measurement of the electric vehicle. The processing device stores a vehicle weight, and receives a value of torque force and two speed measurements of the electric vehicle from the electric motor, obtains an acceleration based on the speed measurements, obtains a current user weight based on the value of torque force, the acceleration and the vehicle weight, and outputs a notification when the current user weight is lower than an initial user weight by a predetermined ratio.

An optical rotary encoder includes a code disk, a laser source unit, a focusing unit and a photodetector array. The focusing unit converts the laser beam emitted by the laser source unit into incident laser beams that have a plurality of light points respectively on code tracks of the code disk, such that the code disk modulates the incident laser beams to form optical code signals. The photodetector array receives and converts the optical code signals into electric code signals.
