Patent number: 11975593Abstract: A heat pump system, a heat management method and a vehicle are provided. The heat pump system includes an integrated heat exchanger integrated with a superconducting liquid flow passage and a refrigerant flow passage. The refrigerant flow passage is provided inside an on-board refrigerant circulation loop and is used for cooling and/or heating to adjust the temperature within a passenger compartment of a vehicle. The superconducting liquid flow passage is in communication with a motor heat dissipating conduit, for absorbing the heat generated by an on board motor and transferring the heat to the integrated heat exchanger by means of phase change heat transfer. The heat pump system can increase the energy utilization rate for the vehicle and reduce the allowable ambient temperature of the heat pump system.Type: GrantFiled: February 17, 2020Date of Patent: May 7, 2024Assignees: ZHEJIANG GEELY HOLDING GROUP CO., LTD., CHONGQING LIVAN AUTOMOBILE R&D INSTITUTE CO., LTDInventors: Lanbao Cao, Quankai Yang, Zhonggang Liu, Xiujuan Xu, Yanlin Liu, Guopin Tong, Chao Gao, Yanli Wang, Songyan Li, Ya Cui, Jingyu Chen, Feng Qiu, Jiaqi Zhang

Patent number: 11941553Abstract: The embodiment of the present disclosure discloses a method, an electronic device, and a storage medium for a ship route optimization. The method for the ship route optimization considers a dynamic feature of a multi-functional emergency rescue ship and an interference effect caused by an airflow, uses a movement model with kinematics non-holonomic constraints, such as a ship total cost assessment function to simulate the movement of the ship, and based on a sparrow search algorithm, learns how to apply the algorithm to a route plan of the emergency rescue ship. The method can improve the ship route optimization algorithm, improve an accuracy and practical applicability of a calculated plan. The method can effectively and accurately locate obstacles and hidden reefs, and consider effects of an airflow and a non-holonomic constraint effect, so as to make the route planning of the ship more efficient and intelligent.Type: GrantFiled: July 5, 2023Date of Patent: March 26, 2024Assignees: HEFEI UNIVERSITY OF TECHNOLOGY, ANHUI CONSTRUCTION ENGINEERING TRAFFIC & SHIPPING GROUP CO., LTD.Inventors: Jingyu Yu, Jingfeng Wang, Wei Lin, Yuxue Pu, Yongchao Zhu, Zhenxuan Li, Qiong Zhang, Yuming Zhang, Yonggen Gu, Zheng Qiu

Patent number: 8665310Abstract: Techniques to provide active lighting control for video teleconferencing systems are described. In an embodiment, a video teleconferencing (TVC) device receives lighting data from cameras in a room where a VTC is taking place. The VTC device may access lighting profiles for the lights in the room from a lighting control system. The VTC device may compare the current lighting conditions to a target model. The VTC device may use the lighting profiles to select lights to turn on or off via the lighting control system to improve the lighting. The VTC device may monitor the lighting conditions during the conference and may re-adjust the lights if a large change occurs. Other embodiments are described and claimed.Type: GrantFiled: February 4, 2011Date of Patent: March 4, 2014Assignee: Microsoft CorporationInventors: William Verthein, Jingyu Qiu

Patent number: 8189492Abstract: Architecture for enabling a communications endpoint to quickly recover from a packet loss, reducing duration of a signal dropout. A communications component sends a downlink of dependency-structured signals, such as audio and/or video signals using compressed frames between key frames. A multipoint control component (MCC) is located between the communications component and multiple endpoints, and distributes the downlink to the multiple endpoints. A frame caching component caches a key frame of the downlink. If a key frame is lost at one of the endpoints, the endpoint sends a packet loss report to the frame caching component. The key frame is resent from the frame caching component to the endpoint in response to the key frame loss. In this way, the frame caching component can respond to specific frame loss situations on any of the endpoints, without interfering with the performance on the other endpoints.Type: GrantFiled: March 18, 2009Date of Patent: May 29, 2012Assignee: Microsoft CorporationInventors: Jingyu Qiu, Shiwei Wang, Regis J.

Patent number: 8031222Abstract: During remote communication session, there can be situations where information needs to be sent at a high resolution. Sending information at a high resolution allows for the capture of detail that can be lost without the use of a high resolution. A web camera can obtain information in both a higher resolution and standard resolution. A sending component can send this information encoded with markers that allow a receiving component to process and display the information.Type: GrantFiled: April 25, 2007Date of Patent: October 4, 2011Assignee: Microsoft CorporationInventors: Regis J.

Patent number: 7957307Abstract: An error correction system determines a level of error correction protection to apply to a frame of video data to be transmitted by a sending endpoint to a receiving endpoint based on the predicted impact of packet loss as well as the importance of the frame based on inter-frame dependencies, frame size, packet loss probability, historical packet loss pattern, central processing unit (CPU) load, and available network bandwidth. At the receiving endpoint, when packet loss is detected for a particular frame, the receiving endpoint will attempt to recover the frame using protection packets received along with the video data.Type: GrantFiled: March 14, 2007Date of Patent: June 7, 2011Assignee: Microsoft CorporationInventors: Jingyu Qiu, Timothy M.

Patent number: 7869705Abstract: A subject captured by a camera may be affected by environmental lighting provided by nearby light sources and the sun or moon, which may cause underexposure or overexposure of the image or aesthetically displeasing color tones. Image processing and camera adjustments may mitigate some imaging problems with limited effect and introduce undesirable side effects. A lighting array may be devised to expose the subject to various types of light (e.g., white light comprising full spectrum illumination and red, green, and blue lights comprising partial spectrum illumination) to resolve lighting problems in a more effective manner. Moreover, the lighting array may be responsively controlled to adjust the subject image with respect to one or more target spectra specifying desirable colors for the subject image. The lighting array may be iteratively controlled, e.g. by a gradient descent algorithm, for incrementally adjusting parameters with respect to proximate target spectra for the image.Type: GrantFiled: January 21, 2008Date of Patent: January 11, 2011Assignee: Microsoft CorporationInventors: Zicheng Liu, Mingxuan Sun, Jingyu Qiu, Zhengyou Zhang, Michael J.

Patent number: 7652716Abstract: A video communication system may include a computer program that implements a feedback control process for automatically controlling a light. The feedback control process may include receiving an image from a video camera and determining an initial difference between the received image and a stored image. For example, the feedback control process may determine, on a pixel-by-pixel basis, whether the color and intensity of a facial region in the captured image is sufficiently close to the color and intensity of a facial region in the stored image. If the difference between the captured image and the stored image exceeds a threshold, the feedback control process includes transmitting an optimization instruction to the light. This optimization instruction, when performed by the light, decreases the difference between the received image and the stored image.Type: GrantFiled: May 31, 2007Date of Patent: January 26, 2010Assignee: Microsoft CorporationInventors: Jingyu Qiu, Regis J.
