Abstract: A hand-push garden tool and a control method thereof. The hand-push garden tool comprises a main body, wheel and a handle assembly. The wheels are mounted on the main body, the handle assembly is mounted on the main body. The handle assembly comprises a handle, a first control rod and a second control rod. The first control rod is mounted on the handle and can rotate relative to the handle, the second control rod is mounted on the handle and can rotate relative to the handle, and the first control rod and the second control rod are coaxially arranged. The first control rod and the second control rod of the hand-push garden tool can coaxially rotate and cannot affect each other, the garden tool is convenient, beautiful and clean and tidy, and design spaces are saved.

Abstract: Disclosed are an antigravity shear-resisting and deformation-eliminating centerless grinding apparatus and a machining method. The grinding apparatus comprises a grinding tool configured to grind a thin-walled bearing ring and a clamping mechanism configured to clamp the thin-walled bearing ring stably. The clamping mechanism comprises a main clamping mechanism and an auxiliary clamping mechanism. The main clamping mechanism comprises an electromagnetic centerless clamp. The electromagnetic coil is arranged above the thin-walled bearing ring being ground. According to the present invention, not only can gravity of the thin-walled bearing ring and a tangential force generated by grinding be counteracted to effectively prevent extrusion deformation of the thin-walled bearing ring when being ground, but also the lubricating performance the capacity to resist load itself can be further improved and the service life of is prolonged.

Abstract: A method includes creating a bulk order. The bulk order includes a plurality of action sets. Each action set represents a set of changes to a plurality of assets, and the bulk order represents, for a plurality of accounts, a plurality of services and assets. The method also includes validating the bulk order. The validating includes verifying a validity of a user name, which includes a validity of an association between the user name and the account and a validity of an association between the user name and the service. The validating also includes verifying the action set obeys a constraint of the product. The method also includes submitting the bulk order for execution of the set of changes. The submitting includes preparing the action set, executing the set of changes and changing a status of the bulk orders header to indicate a completion of the bulk order.

Abstract: A service providing system comprising a server device, a terminal device, and a service providing device in combination with an optical wireless tag device to achieve transmitting of ID, password, or other service information stored in the service providing device in a non-contact and non-broadcasting manner, thus enabling highly secured and reliable services.

Abstract: The travel range is extended for electrostatically actuated micro mirrors used as attenuators, modulators and switches in optical networks by the use of dielectrically coated, preferably with Silicon dioxide, inner surfaces. Oxide charge and oxide capacitance combine to expand the travel range of the mirrors before snap down, at the expense of increased applied bias voltage. This method of travel range extension is preferred over other range extension methods due to its simplicity, reproducibility, and ease of manufacture, as well as benefits of decreased stiction and inhibited electrode shorting. A method for the manufacture of the devices is also disclosed.
