An input pen (60) of the present invention is an input pen used for performing an input to a touch-panel-integrated liquid crystal display device (100) (display device). The liquid crystal display device (100) includes a plurality of photosensitive elements (30) that senses light transmitted through a panel surface. The photosensitive elements (30) detect a position of input by sensing an image on a surface of a display panel. The input pen (60) includes a retroreflective element (61) at its tip that is to be in contact with the display panel. The retroreflective element (61) is made up of a spherical glass (62) (spherical transparent member) and an elastic reflective element (63). In this way, it is possible to provide an input pen which is to be used with a touch-panel-integrated display device and which makes it possible to perform a more accurate position detection.

An information processing method, system and an electronic device are provided according to the embodiments of the disclosure, and applied to an electronic device having at least a first panel, with a first surface of the first panel being provided with a display unit and at least one image acquisition apparatus, where the at least one image acquisition apparatus is positioned below the display unit in the case that the first panel stands on a plane. After an image for a to-be-recognized object and the plane is acquired by the image acquisition apparatus, whether the object contacts the plane is determined based on the acquired image, and information about position change on the object is detected in the case that it is determined that the object contacts the plane.

The invention relates to an automatic welding method based on a three-dimensional model and machine vision and a welding device based on the three-dimensional model and the machine vision, relating to the technical field of welding. An industrial camera is used for acquiring an image of a workpiece to be welded; three-dimensional match is carried out and the workpiece to be welded is positioned according to the three-dimensional model of the workpiece; a welding line is positioned according to welding line information in the three-dimensional model; the welding line is accurately positioned by using a structure optical sensor; a movement track of a welding gun is adjusted according to the accurate position of the welding line so as to accurately track and weld the welding line. According to the automatic welding method, an automatic positioning and tracking function of the welding line can be realized, and the reliability of tracking the welding line and the tracking precision are improved. The problems that the welding precision is influenced, caused by the fact that the workpiece is warped by thermal deformation in a welding process and the like are solved; the adjustment and the adaptation can be carried out very well and the welding quality is improved.

A monitoring device (100) for a loom (2), comprising at least one camera device (20) and a weft yarn beating device (1), wherein the weft yarn beating device (1) comprises at least one reed ( 13) and / or the sley (17), and the reed (17) and / or the sley (13) extend along the longitudinal direction (LA1, LA2) of the weft thread beating device (1). At least one camera device (20) is fixed to the weft thread beating-up device (1) and comprises a plurality of sensor elements arranged next to each other. The camera device (20) is designed to record images by means of sensor elements, wherein the sensor elements are arranged in a row extending approximately parallel to the longitudinal direction (LA1, LA2) of the weft thread beating-up device (1).

The invention relates to a safety seat control method, a safety seat and a corresponding vehicle. The safety seat comprises a seat body and a safety belt and further comprises a swing arm arranged on a backrest of the seat. The swing arm is provided with a connecting end and a swing end. The swing end is provided with a containing position used for containing the safety belt and a releasing position used for releasing the safety belt in the swing stroke of the swing end. The swing arm contains the safety belt in the containing position on the upper rear side or over the backrest of the swing arm, and the swing arm releases the safety belt in the releasing position in front of a passenger. The swing end is provided with a controlled-separable type combining device which is used for being separably connected with the safety belt. The connecting end is connected with a power device which is used for driving the swing arm to swing. The safety belt is driven to swing through the swing arm. The safety seat is wide in applicability and capable of being used universally.

The present invention provides an elevator apparatus, capable of being controlled to run when there is an earthquake even though a detector used in common is fault. A first (used under normal condition) detector is arranged in an elevator car running in a lifting channel, a first (used under normal condition) parking position detecting body is arranged on a parking position of the elevator car onthe lifting channel side in a projecting manner such that the first detector detects the parking position of the elevator car when it faces to the first detector. In the elevator apparatus capable ofbeing controlled to run by an earthquake detector when there is an earthquake, a second (used under emergent condition) wide detector is arranged in the elevator car, and a second (used under emergent condition) parking position detector is arranged on a position facing to the second detectoron the lifting channel side, when the earthquake detector plays a function of switching so as to use the second detector in control.

The invention relates to a safety belt fastening device. The safety belt fastening device comprises an inversed-L-shaped swing arm arranged on one side of a seat. The swing arm comprises a connecting end connected with the seat and a swing end. The connecting end is located on a vertical arm body of the swing arm, and the swing end is located on a transverse arm body of the swing arm. The swing end has a containing position where a safety belt is contained and a releasing position where the safety belt is released in the swing stroke of the swing end. When the swing end is located at the containing position, the swing arm is located above the back of a backrest or located right above the backrest to contain the safety belt. When the swing end is located at the releasing position, the swing arm is located in front of a passenger to release the safety belt. A control-separable combining device is arranged at the swing end and used for being connected with the safety belt in a separable manner. An assembling part connected with a power mechanism in a transmission manner is arranged at the connecting end. As the safety belt is driven by the swing arm to swing, the safety belt fastening device has the wide applicability and can be generally applicable.
