摘要:
The present invention presents a bionic automatic vision and line of sight control system and method, wherein the system comprises multiple camera sets, wherein each camera set comprises one or more parallel camera with different shooting range, wherein each camera set is driven by one or three actuators, capable of rotating in two or three degree of freedom. The present system is capable of fast object positioning, high accuracy tracking and wide range compensation for line of sight deviation caused by the movement of the system. More specifically, the system can ensure two camera sets to position and track the same object at the same time. The present system not only can be used in various fixed places to monitor, protect and care taking, it can also be installed on various moving objects, such as cars, airplanes, boats, military equipments, and it can be used as eyes for various types of robots.

The present invention relates to the field of grinding equipment, in particular to a powder grinder, comprising a power mechanism, a grinding mechanism, and a feeding mechanism. The feeding mechanism comprises a bowl and a base. The bowl is detachably installed on the base, and the power mechanism is detachably installed on the bowl. The first discharge opening is arranged in the middle of the bowl, and the second discharge opening is arranged in the middle of the base. An adjusting plate is rotatably installed on the base. The third discharge opening is arranged in the middle of the adjusting plate. An adjusting ring is arranged between the bowl and the base. The second connecting assembly is arranged between an inner edge of the adjusting ring and an outer edge of the adjusting plate. A bearing is arranged in the bowl. One end of the bearing is connected to the power mechanism, and the other end of the bearing passes through the first discharge opening, the third discharge opening, and the second discharge opening in sequence and is connected to the grinding mechanism for separate removal and cleaning of the bowl, the base, and the grinding mechanism. When cleaning, the power mechanism can be separately detached, which effectively prevents liquid from entering the inside of the power mechanism.

The user wearable devices are configured to allow attendees of events to exchange their information upon a simultaneous input into their respective device. The simultaneous inputs initiate a verification that the two users are registered for and present at the same event before initiating a pairing through single direction short range antennas. The simultaneous inputs can also verify whether the two users are facing one another and an appropriate distance apart to coordinate the simultaneous input.

The present invention discloses a method for dynamic two-way auction, applicable for auctioning participating goods, comprising: (1) setting, by a server. The descriptive information, possible search conditions and the relations which associate each search condition with the descriptive information of all participating goods are set up and stored on the server side; (2) sending, by a buyer terminal and/or a seller terminal, a search request which includes a search condition to the server; (3) parsing, by the server, the search request to obtain the search condition, determining whether a definition of a relation which associates the search condition with the descriptive information has been recorded, and performing step (4) if the relation has not been recorded; (4) defining, by the server, a relation which associates the search condition with the descriptive information of some participating goods.
摘要:
In a 3D free space micromirror device, a mirror plate is joined with actuators through flexible springs where the other ends of the actuators have fixed support on the substrate. Single crystal silicon and aluminum are used as bi-morph materials with silicon dioxide providing electrical isolation between the two. Thickness variation in the microstructure is achieved by two-step p-n junction formed in a p-type substrate. Thick and thin n-silicon layer formation and DRIE cut mechanisms are employed in such a way that all the thick and thin silicon components of the structure are released simultaneously avoiding overetch which can be detrimental to the thin flexural springs. Working prototypes of the device have been found suitable for any optical switching array architecture where deflections up to 10 degrees are required.
