Patent number: 12228289Abstract: A latching structure for a cooking device and a cooking device having the same are provided. The cooking device has a casing and a door body. The latching structure has a flipping member, a first restoring member, a restricting member and a second restoring member. The first restoring member provides the flipping member with a first restoring force for allowing the flipping member to rotate towards a non-triggered position. The restricting member is movably disposed on the casing between a first position and a second position. The second restoring member is configured to provide the restricting member with a second restoring force for allowing the restricting member to move towards the first position. The latching structure is configured, such that a restoring speed at which the flipping member rotates towards the non-triggered position is greater than a restoring speed at which the restricting member moves towards the first position.Type: GrantFiled: April 14, 2022Date of Patent: February 18, 2025Assignees: GUANGDONG MIDEA KITCHEN APPLIANCES MANUFACTURING CO., LTD., MIDEA GROUP CO., LTD.Inventors: Xin Zhang, Yanqi Wu, Shuaishuai Wei, Xinchao Zhu

Patent number: 12211466Abstract: Methods and apparatus for graphics processing, such as producing a smooth transition between images of different dynamic ranges (e.g., Standard Dynamic Range (SDR) images and High Dynamic Range (HDR) images). An example method generally includes using a high frame rate during a transition period to allow properties of images to incrementally vary. The properties may include brightness (i.e., luminance), color gamut, tone mapping, among others. For example, during the transition period, a subset of HDR images are displayed at a second frame rate (e.g., 120 Hz) higher than a frame rate based on the HDR images (e.g., 30 Hz). Simultaneously, a brightness level (as well as other aspects) of the display panel is adjusted incrementally from an SDR brightness level to an HDR brightness level during the transition time period over the subset of the HDR images.Type: GrantFiled: April 14, 2021Date of Patent: January 28, 2025Assignee: QUALCOMM IncorporatedInventors: Nan Zhang, Ike Ikizyan, Xinchao Yang, Zhizhou Chen

Patent number: 8755903Abstract: The present invention discloses a functional electrical stimulation system comprising a primary power, a boost module, an energy storage section, an output control relay, an automatic discharge circuit, a foot/hand controlled switch, a current detection chip and a current limiting fuse. The boost module comprises n DC chopper circuits connected in series, and outputs a high voltage of 100-200V. According to an enable signal and a current detection signal, the output control relay disables/enables the DC boost module. The automatic discharge circuit discharges capacitance of the energy storage section automatically when the relay turns off the power input. The Foot/hand controlled switch, the current detection chip and the current limiting fuse form a triple accident protection circuit. The functional electrical stimulation system maximizes the intensity of electrical stimulation within the range that the human body can withstand.Type: GrantFiled: June 28, 2011Date of Patent: June 17, 2014Assignee: Institute of Automation, Chinese Academy of SciencesInventors: Zengguang Hou, Min Tan, Yixiong Chen, Pengfeng Li, Hongbo Wang, Long Cheng, Guoqing Hu, Qingling Li, Feng Zhang, Jin Hu, Xinchao Zhang, Yi Hong, Junwei Zhang, Jinzhu Bai, Zhen Lv
