Abstract: A multi-axis turntable includes a base, a rocker arm and a first driving device capable of driving the rocker arm to rock around the first rotation axis on the base. A swing arm and a second driving device, which is capable of driving the swing arm to swing around the second rotation axis on the rocker arm, are provided on the rocker arm. A workbench and a third driving device for driving the workbench to rotate around the third rotation axis are provided on the swing arm. The second rotation axis and the third rotation axis are parallel to each other or on different planes. Compared with the existing double rotating shaft turntable, the multi-axis turntable of the present invention has a cutting tool system of good and stable rigidity.

Abstract: In some examples, an embolization device includes multiple sections with three-dimensional non-helical structures when deployed at a vascular site. The multiple sections include a first section and one or more second sections that are smaller than the first section. The first section may have a deployed structure configured to anchor the device at a vascular site (e.g., a blood vessel) of a patient while each of the one or more second sections may be formed from loops that configured to pack and obstruct the vascular site. In some cases, the embolization device also includes a third section having a deployed configuration with multiple helical windings or loops is configured to anchor the embolization device at the vascular site.

Abstract: The present application discloses a bird-repelling method, a bird-repelling apparatus, and a bird-repelling system. The bird-repelling method includes steps of: controlling a light-emitting device to emit blue light; controlling a sound producing device to emit sound waves; and repelling birds by the bird-repelling apparatus integrating blue light irradiation and sound wave emission. The blue light bird-repelling mode and the sound wave bird repelling mode complement each other. Light waves and sound waves generate a resonance effect, which can repel birds more effectively without causing harm to humans or birds. The present application can be widely applied to various fields requiring bird repelling, such as aviation, high-speed railways, electric power, agriculture, and the like.

Abstract: The present invention discloses novel aromatic ketone compounds with functional substitution groups at para- or meta positions which can be used as photo-initiators or effective components of photo-initiator mixtures for the photopolymerizations of ethylenically unsaturated systems. The preparation of these compounds is also disclosed.

Abstract: A data processing system which allows a user to interactively identify a portion of a volume and display the identified portion of the volume in a way that is particularly adapted for the visualization of the identified portion of the volume. One embodiment provides identifying a location of a volume based on input communicated via an input interface having at least 3 degrees of spatial freedom for input control; and displaying the volume with an unobstructed partial view path through the volume to a portion of the volume at the identified location. In one embodiment, the input interface includes a hand held device; and the displaying further comprises displaying a virtual tool corresponding to a location of the hand held device. For example, a portion of the volume is displayed at the location within the volume, as if a tunnel to the portion of volume were provided.

Abstract: A data processing system which allows a user to interactively identify a portion of a volume and display the identified portion of the volume in a way that is particularly adapted for the visualization of the identified portion of the volume. One embodiment provides identifying a location of a volume based on input communicated via an input interface having at least 3 degrees of spatial freedom for input control; and displaying the volume and separately displaying a portion of the volume corresponding to the location. In one embodiment, the input interface includes a hand held device; and the displaying further comprises displaying a virtual tool corresponding to a location of the hand held device. For example, a slice of a volume can be selected and displayed in an orientation that maximizes a displayed size and is consistent with the orientation of the slice in a 3D view of the volume.
