85 results about "Physical body" patented technology

In common usage, a physical object or physical body (or simply an object or body) is a collection of matter within a defined contiguous boundary in 3-dimensional space. The boundary must be defined and identified by the properties of the material. The boundary may change over time. The boundary is usually the visible or tangible surface of the object. The matter in the object is constrained (to a greater or lesser degree) to move as one object. The boundary may move in space relative to other objects that it is not attached to (through translation and rotation). An object's boundary may also deform and change over time in other ways.

Head-mounted bag-type miniature semiconductor cooling ice belt

The invention relates to the field of semiconductor refrigerating and domestic medical physical body coolers, in particular to a head-mounted bag-type miniature semiconductor cooling ice belt comprising a water bag. The water bag is loosely connected with a head belt through belt loops arranged on the water bag. The head belt is a combination member; the middle of the head belt is provided with a cold transfer plate; one side of the cold transfer plate is attached to the water bag, and the other side of the cold transfer plate is attached to a cooling face of a cooler; fixing belts are connected to left and right sides of the head belt. The heating face of the cooler is attached to a heat transfer plate of a heat tube radiator. The heat tube radiator is a combination member composed of the heat transfer plate, heat tubes, and a plurality of radiating fins; the heat tube radiator is used for transferring heat from the forehead to the outside for cooling. A sponge pad is arranged around the cooler. A cooling fan is mounted on the heat tube radiator. The head belt, the cooler, the sponge pad and the heat tube radiator are integrally connected through screws by the aid of through holes in the cold transfer plate in the middle of the head belt and screw holes in the heat transfer plate of the heat tube radiator.

A creation method of candidate set for physical body-clothe confliction detection

InactiveCN101261745ASpeed ​​up the conflict detection processImprove computing efficiencyAnimation3D-image renderingRelative displacementHuman body
The invention discloses a building method for a candidate set used for detecting a human body-clothes conflict which mainly includes two steps of building a mother candidate set and a sub candidate set. Aiming at each human body primitive, the invention takes a clothes primitive which can conflict with the human body primitive and is apart from the human body primitive in a certain range as a composition element of the candidate set according to the neighboring position relation of the corresponding primitives on a human-clothes model and the characteristic of small relative displacement when moving, wherein, the building of the mother candidate set is finished at a pre-treating stage when the human body clothes is in a static state, a larger value can be selected as the distance range so as to avoid detection leakage; the sub candidate set is built or updated at an animation stage, a smaller value is selected as the distance range so as to reduce the detecting times among the primitives and improve the efficiency of the conflict detection. The detection process of the conflict between the human body model and the clothes model in a virtual space can be quickened by utilizing the method; the building method of the invention can be applied to relevant applications such as virtual fitting and clothes animation, etc. and has great help for quickening the calculation efficiency of conflict detection.
