The stator for an electric machine includes a ring-shaped stator yoke, on which stator coils, formed on winding bodies and distributed uniformly around the circumference, are mounted. The coils are wired electrically together by a wiring arrangement, which has a ring-shaped carrier element designed to be attached to the stator to hold connecting conductors. The carrier element is mounted radially with respect to the winding elements. To ensure a simple and reliable mounting of the carrier element on the stator, it is proposed that the carrier element be held in place on the winding bodies by means of a latching connection so that it cannot move in the axial direction.

This application concerns a comb (200) for a hair clipper comprising a comb portion (208) comprising a plurality of comb teeth (216) having slots formed there between for guiding hairs to a cutting element of the hair clipper. The comb portion may be configured such that, when the comb is attached to the hair clipper, a substantially wedge-shaped hair debris-receiving space is formed between the housing and the comb portion into which hair debris can flow. The comb teeth may comprise an extension portion (230) which extends generally forwardly away from the respective comb tooth in a cutting movement direction such that a connecting bar is spaced apart from a housing of the hair clipper by a greater distance than the plurality of comb teeth.

The invention discloses a 360-degree three-dimensional display device based on splicing of multiple high-speed projectors. The 360-degree three-dimensional display device comprises an orientation diffuser screen set, a rotating device set, a rotating detection module, a projection splicing integration module, image storage modules and the N high-speed projectors. An algorithm of splicing of the multiple high-speed projectors is used for calculation to obtain a two-dimensional frame image sequence projected by each high-speed projector in real time, and the two-dimensional frame image sequences are sent to all the image storage modules. Under modulation of the rotating detection module, all the high-speed projectors are controlled to be matched with rotation of one set or more sets of orientation diffuser screens, splicing and synthesizing imaging of projection areas of all the high-speed projectors are achieved, and the space resolution ratio of three-dimensional display is improved in a multiplied mode. The algorithm based on splicing of the high-speed projectors is matched with the orientation diffuser screens for imaging, the three-dimensional imaging space is enlarged, the transverse dimension, the longitudinal dimension and the field depth dimension of a three-dimensional image are increased, and spatial expansion of three-dimensional display of the large-dimension space is achieved.

The invention discloses a cache replacement method in a heterogeneous memory environment, which is characterized in that it includes: adding a source flag bit in the cache line hardware structure to mark whether the cache line data comes from DRAM or PCM; A new sampling storage unit is added in the CPU, which is used to record program memory access behavior and data reuse distance information; it also includes three sub-methods: sampling method, equivalent position calculation method and replacement method. Sampling statistics, the equivalent location calculation submethod is used to calculate the equivalent location, and the replacement submethod is used to determine the cache line that needs to be replaced. The present invention optimizes the traditional cache replacement strategy for the memory access characteristics of programs in a heterogeneous memory environment. The implementation of the present invention can reduce the high delay cost of accessing PCM memory due to cache misses, thereby improving the overall memory access of the system performance.

The invention discloses a permanent magnetic wind electric generator control method based on a power factor correction and rectification algorithm in micro grid construction. A three-phase PMSG is controlled through a PFC method, and in order to meet the requirement for rotor position information needed in the control, an original position di / dt detection method, a rotation high-frequency voltage injection method and a double-salient-pole decoupling observer are combined. The three-phase PMSG is controlled through the PFC method, the original position di / dt detection method, the rotation high-frequency voltage injection method and the double-salient-pole decoupling observer are combined to accurately and effectively provide accurate and reliable rotor position information to current control of the PMSG, so that current harmonic content is reduced, power factors in the PMSG approach 1, direct-current output is maintained, and good control of the PMSG based on the PFC method is achieved.
