Disclosed is a non-blind-area multi-view panoramic stereo imaging device. The device comprises a front lens assembly or a plane mirror, an aspheric mirror, a middle lens assembly, a panoramic block, a rear lens assembly and an image surface which are longitudinally arranged along an optical axis. The aspheric mirror comprises a central hole and an annular reflecting surface. The panoramic block comprises a front central circular transmission surface, a front reflecting surface, a front transmission surface, a rear reflecting surface and a rear transmission surface. The front reflecting surface, the front transmission surface and the rear reflecting surface are all annular surfaces. The inner edge of the front reflecting surface is connected with the edge of the front central circular transmission surface.

Non-blind-area multi-view panoramic stereo imaging device

A 4K high-resolution panoramic annular optical system includes a panoramic annular lens head unit, a subsequent lens group, and a 4K sensor (SE) that is coaxially installed. The panoramic annular lens head unit includes a first lens (PALIPAL) and a second lens (PAL). The subsequent lens group includes a third lens (RL), a fourth lens (RL), a fifth lens (RL), a sixth lens (RL), a seventh lens (RL), an eighth lens (RL), and a ninth lens (RL) that are arranged in order from an object plane to an image plane. The first lens (PAL) and the fifth lens (RL) are meniscus glass lenses with positive refractive power. The six lens (RL) and the ninth lens (RL) are meniscus glass lenses with negative refractive power, and the second lens (PAL), the fourth lens (RL), the seventh lens (RL), and the eighth lens (RL) are biconvex lenses with positive refractive power.

4K high-resolution panoramic annular optical system

An electric tool includes a rotary wheel driven to rotate around a central axis thereof, an action member configured to bear a cutter of the electric tool, and a counterweight. The rotary wheel drives the action member such that it reciprocates linearly in a first direction. The rotary wheel simultaneously drives the counterweight such that it not only reciprocates linearly in the first direction in an opposite manner to the action member, but also performs reciprocating swinging movement in a plane perpendicular to the central axis. The first direction is parallel to the plane.

Power tool

The present disclosure relates to a hand-held machine tool. The hand-held machine tool includes: a first moving component as a main vibration source, the first moving component reciprocating substantially in a straight line in a first direction; a second moving component as a secondary vibration source, the second moving component having a movement state different from that of the first moving component; and a balancing block, with a linear movement direction of the balancing block being a second direction in a different plane from that of the first direction, and a movement pace of the balancing block being opposite to that of the first moving component.

Handheld machine tool

Providing object information on the Internet includes configuring a plurality of front-end categories for a plurality of network objects and a plurality of screening conditions for screening the plurality of network objects, where each of the plurality of screening conditions uniquely corresponding to a respective one of the plurality of the front-end categories. Providing object information further includes receiving object information pertaining to a network object, the object information including a screening condition for the network object; storing the object information in a back-end category, determining a front-end category to which the network object belongs, according to the screening condition and storing correlation information of the object and the front-end category, wherein the back-end category is separate from and different than the front-end category.
