  • Publication number: 20230403008
    Abstract: The present application provides an input device. The input device comprises a key module, a capacitance detection module and a control module. The key module receives a physical pressing signal and correspondingly feeds back a capacitance change signal, the capacitance detection module receives the capacitance change signal from the key module and determines the working state of the key module, and the control module receives the determination result from the capacitance detection module and correspondingly generates an input signal. The key module comprises a key switch and a capacitor circuit arranged in series. The key module responds to the external physical pressing signal, and correspondingly adjusts the capacitance value change of the key module. By serially connecting a capacitor circuit, the sensitivity of determining the working state of a key module is improved, the requirements for assembly precision of a key switch are reduced, and the installation difficulty of products is reduced.

  • Patent number: 11819058
    Abstract: Disclosed are an electronic cigarette and a vaporizer thereof which are suitable for adjusting air inflow with a single hand. The electronic cigarette vaporizer includes a vaporizer base and a liquid reservoir connected to the vaporizer. An atomizing cavity is formed by an internal cavity obtained by the connection of the liquid reservoir and the vaporizer base. An air inlet passage communicated with the atomizing cavity is arranged at the liquid reservoir. An adjusting knob at the entrance of the air inlet passage for adjusting air inflow is also arranged at the liquid reservoir. An air inlet is arranged at the adjusting knob. By rotating the adjusting knob, the air inflow can be adjusted by relative position changes of the air inlet and the entrance of the air inlet passage.

  • Patent number: 11790633
    Abstract: The disclosure provides a learning framework that unifies both semantic segmentation and semantic edge detection. A learnable recurrent message passing layer is disclosed where semantic edges are considered as explicitly learned gating signals to refine segmentation and improve dense prediction quality by finding compact structures for message paths. The disclosure includes a method for coupled segmentation and edge learning. In one example, the method includes: (1) receiving an input image, (2) generating, from the input image, a semantic feature map, an affinity map, and a semantic edge map from a single backbone network of a convolutional neural network (CNN), and (3) producing a refined semantic feature map by smoothing pixels of the semantic feature map using spatial propagation, and controlling the smoothing using both affinity values from the affinity map and edge values from the semantic edge map.

  • Patent number: 11295514
    Abstract: Inverse rendering estimates physical scene attributes (e.g., reflectance, geometry, and lighting) from image(s) and is used for gaming, virtual reality, augmented reality, and robotics. An inverse rendering network (IRN) receives a single input image of a 3D scene and generates the physical scene attributes for the image. The IRN is trained by using the estimated physical scene attributes generated by the IRN to reproduce the input image and updating parameters of the IRN to reduce differences between the reproduced input image and the input image. A direct renderer and a residual appearance renderer (RAR) reproduce the input image. The RAR predicts a residual image representing complex appearance effects of the real (not synthetic) image based on features extracted from the image and the reflectance and geometry properties. The residual image represents near-field illumination, cast shadows, inter-reflections, and realistic shading that are not provided by the direct renderer.
