Abstract: A heating device for heating clothing and a heating clothing include a controller, wires, wire carriers, and heating sheets. Each of the wires is electrically connected to the controller and corresponding heating sheets. The controller is configured to control the heating device. at least a part of the wires are arranged on the wire carriers. the part of the wires arranged on the wire carriers are in a bent shape. When the wires are pulled, the part of the wires on the wire carriers that are in a bent shape provide extra stretched length to avoid pulling on connection between the wires, the controller, and the heating sheets. Meanwhile, the wire carriers share pulling force and reduce pulling on the wires. Thus, the wires are not easily pulled, and a problem of poor electrical connection is avoided.

Abstract: The present application relates to the field of monitoring, and discloses a method and a device for obtaining evidences for illegal parking of a vehicle. In the method for obtaining evidences of the present application, a correspondence relationship between shooting positioning parameters of a first camera and a second camera is preset. The method for obtaining evidences comprises: taking a first photo of an illegally parked vehicle using the first camera and obtaining a current first shooting positioning parameter of the first camera; according to the correspondence relationship, calculating a second shooting positioning parameter of the second camera corresponding to the first shooting positioning parameter and controlling the second camera to take a second photo with the second shooting positioning parameter. Thereby the photos of the head and rear of the illegally parked vehicle are obtained simultaneously as the evidences for illegal parking for penalty.

Abstract: A system and method for determining a set of visualization points from any given two-dimensional dataset to best describe a given visual analytic. A first user selection is received in a data processing apparatus for a chart. A chart type associated with the first user selection is identified for the chart. One or more visualization strategies are accessed from a strategy pool database based on the chart type. A second user selection is received in the data processing apparatus for a two-dimensional dataset from a data provider in communication with the data processing apparatus. The two-dimensional dataset is analyzed to determine a best strategy from the one or more visualization strategies accessed from the strategy pool database. Metadata representing the two-dimensional dataset is generated based on the best strategy, and a display representing the metadata is generated to visualize the two-dimensional dataset according to the best strategy.

Abstract: An improved structure of applying container including a bottle to receive liquid for applying, the bottle is provided thereon with a connecting seat that has on its top a ball seat for a rollable ball. A displacement means and a stop means are provided between the connecting seat and the ball seat. The displacement means endues the ball seat and the connecting seat with a first kind of relative position after displacement and a second kind of relative position after displacement. When the connecting seat and the ball seat are in the first relative position, the stop means forms a closing state, the liquid for applying in the bottle is prevented from flowing out of the ball, by contact of the rollable ball with skin, a massaging function can be obtained.
