Abstract: Devices and techniques are generally described for learning personalized concepts for natural language processing. In various examples, a first natural language input may be received. In some examples, a determination may be made that the first natural language input comprises non-actionable slot data. A dialog session may be initiated with the user. In some examples, first slot data that is indicated by the user during the dialog session may be determined. In various examples, data representing the first slot data may be stored in a database in association with the first natural language input.

Abstract: A touch sensor and a display apparatus are disclosed. The touch sensor includes a first opening region, first touch electrodes and second touch electrodes. The first touch electrodes respectively extend along a first direction, and at least one of the first touch electrodes includes first touch sub-electrodes arranged side by side in the first direction and electrically connected with each other; the second touch electrodes respectively extend along a second direction, and at least one of the second touch electrodes includes second touch sub-electrodes arranged side by side in the second direction and electrically connected with each other; an area of a first touch sub-electrode in the first region is less than that of a first touch sub-electrode in the third region, or an area of a second touch sub-electrode in the first region is less than that of a second touch sub-electrode in the third region.

Abstract: The present invention discloses a method for producing unidirectional hybrid-braided fabrics, including: preparing a first layer of 0° warps; preparing a second layer of 0° warps to a Nth layer of 0° warps; preparing an auxiliary layer of wefts; preparing binding yarns; laying and hybrid-braiding the materials prepared in steps 1-4 to obtain unidirectional hybrid-braided fabrics; and cutting and winding. The 0° warps and wefts of the invention are made of two or more layers of different fibers that are laid in a single direction and finally hybrid-braided. Therefore, two or more different types of materials can be laid, thereby ensuring the uniform distribution and thickness of the fibers in different areas of the hybrid-braided fabric. The grammage of different 0° warp fiber layers can be adjusted freely in a range of 30-3000 grams/m2, thereby realizing performance and cost designability of a composite material.

Abstract: A laser control circuit, comprising at least two laser tubes and a control unit controlling the at least two laser tubes respectively; the control unit sends control signals to the at least two laser tubes to control startup/shutdown thereof. The control unit comprises: a main pulse signal generator and a logic control unit; the main pulse signal generator, the logic control unit and the at least two laser tubes are connected successively; and the logic control unit classifies the control signals into different types of control signals and sends to the at least two laser tubes, causing the at least two laser tubes to present different working conditions. The laser control circuit has more flexible control over the laser tubes, reduces working current of the laser tubes and allows the working current to be steadier, thus avoiding peak interference.
