The present invention provides an unmanned aerial vehicle (“UAV”) operations system for cleaning one or more designated surfaces such as a solar panel installed on a roof, or the surface of a window, wall, billboard, scoreboard, etc., which may be too high or too far away from a position on the ground which is easily and safely accessible by a person. For solar panels, such cleaning is not only for aesthetic purposes, but must be performed regularly in order to keep the solar panel functioning at peak performance. The system may also include a ground companion vehicle such as an ATV, golf cart, or the like, which can follow an approximation of the UAV's flight path and provide cleaning media and power to the UAV via a tether, allowing the UAV to clean a large number of surfaces before returning to refill or recharge.

An improvement for a bracket assembly of the type used in lifting and supporting a structure or shallow foundation element on a pile is provided. The bracket assembly rests on top of a deep foundation pile positioned adjacent to a structure. The bracket has inside and outside sections, the inside section is a weldment consisting of a bearing member which engages and attaches to the structure or foundation element. The inside section also functions as a guide for installing a pile. The outside section is further divided into upper and lower parts. The lower outside section has a pile guide and a spaced apart U-shaped adjustment bolt that together cradle the pile. The upper outside section caps the pile and attaches to the lower outside section using threadably adjustable rods. The outside section attaches to the inside section thereby fixing the bracket assembly against horizontal translation and rotation about a horizontal axis with respect to the pile.

The invention discloses a curved plate separator. The curved plate separator comprises a plate separator body, a plate separating jig in/out mechanism and an XYZ module plate separating mechanism, wherein a computer is arranged on the left side of the back end of the plate separator; a bottom plate is arranged at the center of the plate separator body, and the plate separating jig in/out mechanismand the XYZ module plate separating mechanism are located at the upper end of the bottom plate; a plate separating jig fixing plate is arranged at the front end of the plate separating jig in/out mechanism, a plate separating jig is arranged at the upper end of the plate separating jig fixing plate, a linear guide rail is arranged at the back end of the plate separating jig in/out mechanism, anda plate separating jig in/out air cylinder is arranged at the left end of the linear guide rail. When the curved plate separator is used, a PCBA plate is clamped by a manipulator, the PCBA plate movesto a plate separating jig to be separated, and the plate separating jig is sent to the XYZ module plate separating mechanism to be separated by means of the plate separating jig in/out air cylinder.The curved plate separator disclosed by the invention is compact in integral structure, extra-high in rigidity, simple and safe to operate and convenient to pick and place products, and improves the productivity greatly and reduces the labor intensity.

The embodiment of the invention provides a method, a device and a system for authentication of WLAN (Wireless Local Area Network) access and relates to the technical field of communication. By means of the method, the device and the system, the authentication of the WLAN access can be performed more conveniently and safely. The method comprises the following steps: receiving guest information transmitted by an authorization terminal by an authorization guaranteeing device, wherein the authorization terminal is a terminal for accessing the authorization guaranteeing device by adopting a guaranteeing person authorization certificate; transmitting an authorization request to an access authorization device, wherein the authorization request contains the guest information; receiving authorization response transmitted by the access authorization device, wherein the authorization response comprises a guest authorization certificate generated by the guest information; in addition, generating an authorization code, and transmitting the authorization code to the authorization terminal, wherein the authorization code comprises the guest authorization certificate and an address of the authorization guaranteeing device; then receiving the authorization request transmitted by the guest terminal, wherein the authorization request comprises the guest authorization certificate; forwarding the authorization request to the access authorization device. The embodiment of the invention is used for the authentication of the WLAN access.

An external ladder assembly for a nacelle of a wind turbine includes at least one ladder having parallel side legs and a plurality of rungs arranged between the parallel side legs. The ladder assembly also includes a ladder platform arranged with the ladder and configured for placement atop the nacelle. Further, the ladder assembly includes a mounting assembly for affixing the ladder platform atop the nacelle. More specifically, the mounting assembly is adjustable between multiple positions so as to level the ladder platform atop the nacelle. Thus, the ladder assembly provides access to one or more uptower, external features of the wind turbine.

The invention discloses a T-shaped automatic nest box. A nest box body (1) of the T-shaped automatic nest box is separated into a left-right two-range egg laying room (19) through an egg channel slotcover (6) and a separation plate (17), C-shaped steel channels (3) are fixedly arranged at the front end and the rear end of the lower portion of the nest box body (1), and locating frames (15) are movably arranged in clamping grooves in the two ends of the C-shaped steel channels (3). Movable standing plates (16) are movably inserted into the locating frames (15), and a hen standing preventing movable triangular plate (9) is arranged at the upper top end of a box body inclined top (2) through spherical movable locating pins (10), and an egg conveying mechanism is inserted into an egg channelslot (20). Due to the fact that hens can enter the T-shaped automatic nest box from the front portion and the rear portion, egg laying is convenient, space is saved, and the efficiency is high; the egg conveying mechanism is arranged on the lower middle portion in the box body, the space utilization rate is high, a movable foldable standing plate and the hen standing preventing movable triangularplate are adopted, the breeding hens can safely go in and out of the nest box when laying eggs, a barton is not occupied, and mounting, demounting and repairing are easy.

The invention discloses a seed dormancy breaking device, and relates to the technical field of agricultural machinery. The device comprises a bottom plate, a lead screw lifting adjusting mechanism, aninclined supporting mechanism, a gastric juice containing barrel, a seed storage barrel and a stirring motor, the lead screw lifting adjusting mechanism is installed on the rear portion of the upperportion of the bottom plate, and a sliding plate is installed at the front end of the lead screw lifting adjusting mechanism. Through arrangement of the gastric juice containing barrel, the seed storage barrel and the stirring motor, seeds to be subjected to dormancy breaking are placed in the gastric juice containing barrel, cattle and sheep gastric juice is added into the gastric juice containing barrel outside the seed storage barrel, the cattle and sheep gastric juice is immersed into the seeds, and the seeds are driven by the stirring motor to roll up and down in the cattle and sheep gastric juice to simulate cattle and sheep gastric movement to digest food; the strong acidity of cattle and sheep gastric juice is used for promoting seed coat decomposition, so that the effect of breaking dormancy of seeds is achieved, and the problems that an existing seed dormancy breaking mode is poor in dormancy breaking effect and high in seed damage rate and does not conform to the green and environment-friendly concept are solved.
