A 3D construction module comprising at least one vertically upstanding panel with first and second mesh layers oriented generally transversely and longitudinally. The first and second mesh layers have at least one rod member mounted to said panel and are vertically spaced from each other. The rod members form a first horizontally projected retention cell to restrict translation of a bar held in said retention cell between said first and second mesh layers. A third mesh can also be provided to form a second retention cell between said second and third mesh layers. The first and second retention cells restrict translation movement longitudinally and transversely of a vertical reinforcement member held in said first and second retention cells, and restrict rotation of the vertical reinforcement member about both a longitudinal axis and a transverse axis of the said 3D construction module. Horizontal reinforcement meshes are features of the invention. Other features of the invention include a trough for holding melted panel material, connectors for connecting rods to panels and associated stopper members. Also included are bracers for joining connectors and other devices related to panel connections.

This invention provides improvements to worm drives for mechanical power transmission and roller wheels and the worm screws for use in such drives. The principal innovation is utilizing conjugate mesh between the worm screw and the roller wheel by shaping both the surfaces of the threads of the worm screw and the driven surfaces of the roller tips so that they become conjugate surfaces that accomplish the most efficient energy transfer.

Previous worm drive approaches have emphasized conforming shapes for the roller tips and the worm screw as well as certain other techniques in an attempt to compensate certain inherent limitations to energy transfer between driving and driven surfaces. This has caused greater energy losses in the gearing mechanism with corresponding decreased power transfer efficiency. The use of conjugate shapes for the roller tips and the driving worm gear surface represents a significant improvement to the concept.

The invention discloses an installation device for an offshore wind generating set. The installation device comprises a positioning mechanism, a fan, a six-dimensional parallel mechanism, a tower pedestal platform and a crane ship; the six-dimensional parallel mechanism is fixed on the tower pedestal platform through the positioning mechanism; the fan penetrates through the six-dimensional parallel mechanism and is fixed through the six-dimensional parallel mechanism; and the crane ship is connected with a fixing mechanism. The six-dimensional parallel mechanism with three working units is adopted in the installation device and does not have a working dead angle, so that deflection of positive deviation and negative deviation of a fan tower cylinder can be realized, and bolt holes in a bolt hole cylinder tower pedestal on fan tower cylinder flanges are quickly aligned. The six-dimensional parallel mechanism can play a role in buffering when the fan tower cylinder declines, so that collision impact between the fan tower cylinder and the tower pedestal is reduced. The six-dimensional parallel mechanism has a series of advantages of high rigidity, high speed, high bearing capacity, small errors, high precision, good power performance and the like and is easy to control, so that positioning and buffering integration of the fan tower cylinder can be realized, and the manufacturing cost is greatly reduced.

The present invention relates to a projection lens shifting mechanism having: a driving apparatus, a first supporting apparatus, a transmitting apparatus, a movable plate and a second supporting apparatus. The transmitting apparatus is driven by the driving apparatus for changing a direction of the torque transmitted by the driving apparatus. The movable plate, on which a projection lens is mounted, is in contact with the transmitting apparatus to be driven by the transmitting apparatus to translate in a perpendicular direction with respect to the central axis of the driving apparatus, whereby providing a user-friendly interface, that is, when it is operated manually, a direction that the user applies force against the driving apparatus is consistent with that the movable plate translates. Furthermore, after two above mechanisms are combined, the projection lens can be positioned in any position of a two-dimensional plane.

Systems, apparatuses, and methods for limiting translation lookaside buffer (TLB) searches using active page size are described. A TLB stores virtual-to-physical address translations for a plurality of different page sizes. When the TLB receives a command to invalidate a TLB entry corresponding to a specified virtual address, the TLB performs, for the plurality of different pages sizes, multiple different lookups of the indices corresponding to the specified virtual address. In order to reduce the number of lookups that are performed, the TLB relies on a page size presence vector and an age matrix to determine which page sizes to search for and in which order. The page size presence vector indicates which page sizes may be stored for the specified virtual address. The age matrix stores a preferred search order with the most probable page size first and the least probable page size last.
