Patent number: 11991027Abstract: Systems and methods for phase demodulation is described. A wireless power transmitter can include a controller, a transmission coil, and an integrated circuit connected to the controller and the transmission coil. The integrated circuit can be configured to measure a voltage of a transmission coil of a wireless power transmitter. The integrated circuit can be further configured to generate, based on the measured voltage, a pulse signal comprising a plurality of pulses. The integrated circuit can be further configured to send the pulse signal to the controller of the wireless power transmitter. The controller can be configured to perform phase demodulation using the pulse signal.Type: GrantFiled: February 23, 2022Date of Patent: May 21, 2024Assignee: Renesas Electronics America Inc.Inventors: Gustavo James Mehas, Giovanni Figliozzi, Xintian Shi, Francesco Santoro

Patent number: 11983926Abstract: A video content recognition method is performed by a computer device, the method including: obtaining an image feature corresponding to a video frame set extracted from a target video; dividing the image feature into a plurality of image sub-features according to a preset sequence, and each image sub-feature having a corresponding channel; choosing, from the image sub-features based on the preset sequence, a current image sub-feature; image sub-feature fusing the current image sub-feature and a convolution processing result of a previous image sub-feature into a fused image sub-feature, and performing convolution processing on the fused image sub-feature, to obtain a convolved image sub-feature corresponding to the current image sub-feature; splicing a plurality of convolved image sub-features corresponding to the plurality of channels of the convolved image sub-feature, to obtain a spliced image feature; and determining video content corresponding to the target video based on the spliced image feature.Type: GrantFiled: February 17, 2022Date of Patent: May 14, 2024Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Yan Li, Bin Ji, Xintian Shi, Bin Kang

Patent number: 11967151Abstract: Embodiments of this application disclose a video classification method performed by a computer device and belong to the field of computer vision (CV) technologies. The method includes: obtaining a video; selecting n image frames from the video; extracting respective feature information of the n image frames according to a learned feature fusion policy by using a feature extraction network, the learned feature fusion policy being used for indicating proportions of the feature information of the other image frames that have been fused with feature information of a first image frame in the n image frames; and determining a classification result of the video according to the respective feature information of the n image frames. By replacing complex and repeated 3D convolution operations with simple feature information fusion between adjacent image frames, time for finally obtaining a classification result of the video is therefore reduced, thereby having high efficiency.Type: GrantFiled: October 29, 2021Date of Patent: April 23, 2024Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Yan Li, Xintian Shi, Bin Ji

Patent number: 11933923Abstract: A detector system which can be switched between single photon counting and charge integrating mode depending on the application, the photon flux and energy. Although the space for electronics in a pixel or strip detector system is very limited (as each channel is limited by the pixel size), the reconfiguration of the analog chain and the logic/counter in this smart way yields to have a detector system allowing both modes of operation and, therefore, effectively combining the characteristics of an Eiger® single photon counting system and a Jungfrau® charge integrating pixel detector system into one single detector. Depending on the application, the flux and the photon energy, the operator is enabled to switch between single photon counting and charge integrating mode of operation.Type: GrantFiled: September 28, 2020Date of Patent: March 19, 2024Assignee: Paul Scherrer InstitutInventors: Gemma Tinti, Xintian Shi, Roberto Dinapoli, Bernd Schmitt, Aldo Mozzanica

Patent number: 10356342Abstract: An X ray detector with single photon measurement capabilities includes a layer of photosensitive material and an N×M array of photo-detector diodes in the layer of photosensitive material. The photo-detector diodes have a bias potential interface and a diode output interface. An N×M array of high gain, low noise readout unit cells are assigned to the photo-detector diodes. Each readout unit cell has an input interface connecting the diode output interface to a high-gain charge-to-voltage amplifier with integration capacitors. The high-gain charge-to-voltage amplifier can switch between different gains. A comparator and a digital block monitors the charge of the integration capacitance and switches the gain depending from the monitored charge of the integration capacitance. The pixel detector provides the possibility of in pixel intermediate evaluation of an automatic gain switching circuit state to increase the dynamic range of the detector in case of quasi continuous incoming particle flux.Type: GrantFiled: July 15, 2016Date of Patent: July 16, 2019Assignee: Paul Scherrer InstitutInventors: Dominic Greiffenberg, Aldo Mozzanica, Xintian Shi, Bernd Schmitt
