Patent number: 11399069Abstract: A home computing system (cloud) integrates a protocols gateway, WiFi router, cloud server, and mass storage device to support one or more Internet of Things (IoT) devices, possibly with different connectively protocols, in a local environment such as a residential home. The home computing cloud often reduces the amount of data traffic sent to a public computing cloud by locally processing collected device data rather than by sending the device data to the public computer cloud for processing. The home computing cloud may download an appropriate data analytic model from the public computing cloud, locally train (for example, reinforcement learning) the model, and locally execute the trained model to obtain prediction information from collected IoT device data. The home computing cloud also allows direct access of the connected IoT devices by user applications via the internet, through a protocols gateway and an IoT message translator.Type: GrantFiled: April 6, 2020Date of Patent: July 26, 2022Assignee: Computime Ltd.Inventors: Yau Wai Ng, Hung Bun Choi, Chun Kit Chu

Patent number: 11179064Abstract: Various embodiments of a vision-based privacy-preserving embedded fall-detection system are disclosed. This embedded fall-detection system can include one or more cameras for capturing video images of one or more persons. Moreover, this embedded fall-detection system can include various fall-detection modules for processing the captured video images including: a pose-estimation module, an action-recognition module, and a fall-detection module, all of which can perform the intended fall-detection functionalities within the embedded system environment in real-time in order to detect falls of the one or more persons. When a fall is detected, instead of sending the original captured images, the embedded fall-detection system can transmit sanitized video images to the server, wherein each detected person is represented by a skeleton figure in place of the actual person images, thereby preserving the privacy of the detected person.Type: GrantFiled: November 2, 2019Date of Patent: November 23, 2021Assignee: Altum View Systems Inc.Inventors: Him Wai Ng, Xing Wang, Jiannan Zheng, Andrew Tsun-Hong Au, Chi Chung Chan, Kuan Huan Lin, Dong Zhang, Eric Honsch, Kwun-Keat Chan, Minghua Chen, Yu Gao, Adrian Kee-Ley Auk, Karen Ly-Ma, Adrian Fettes, Jianbing Wu, Ye Lu

Publication number: 20210349485Abstract: Electronic thermostats are expanding to a higher integration of services that includes, for example, the integration of a home Internet-of-Things (IoT) gateway, local rule control, local machine learning capability, and higher resolution thin-film transistor (TFT) display. However, the required incorporation of higher processing power control units and/or large display typically results in a higher heat dissipation of electronic components, thus increasing the temperature around the components of an electronic thermostat. The system heat dissipation consequently degrades the accuracy of the on-board temperature sensors. An aspect of the embodiments provides a compensation for the temperature rise effect on the printed circuit board (PCB) of the electronic thermostat to obtain better precision and performance. Once the measurements from the temperature sensors have stabilized, the compensated ambient temperature may be used by an associated system (for example, a HVAC system).Type: ApplicationFiled: May 6, 2020Publication date: November 11, 2021Inventors: Yau Wai Ng, Hung Bun Choi, Chun Kit Chu

Publication number: 20210249013Abstract: An apparatus supports smart assistant services with a plurality of smart service providers. The apparatus includes an audio device that receives a speech signal having a user utterance, captures the user utterance when the user utterance includes a user wake word, and sends the captured utterance to a backend computing device. The backend computing device replaces the user wake word with specific wake words associated with different smart service providers. The processed utterances are then sent to selected smart service providers. The backend computing device subsequently constructs feedback to the user utterance based on voice responses from the different smart service providers. The backend computing device then passes a digital representation of the feedback to the audio device, and the audio device converts the digital representation to an audio reply to the user utterance.Type: ApplicationFiled: April 26, 2021Publication date: August 12, 2021Applicant: Computime Ltd.Inventors: Hung Bun Choi, Kai Nang Pang, Yau Wai Ng, Chi Chung Liu, Tsz Kin Lee

Patent number: 10943096Abstract: Embodiments described herein provide various examples of a face-image training data preparation system for performing large-scale face-image training data acquisition, preprocessing, cleaning, balancing, and post-processing. The disclosed training data preparation system can collect a very large set of loosely-labeled images of different people from the public domain, and then generate a raw training dataset including a set of incorrectly-labeled face images. The disclosed training data preparation system can then perform cleaning and balancing operations on the raw training dataset to generate a high-quality face-image training dataset free of the incorrectly-labeled face images. The processed high-quality face-image training dataset can be subsequently used to train deep-neural-network-based face recognition systems to achieve high performance in various face recognition applications.Type: GrantFiled: December 31, 2017Date of Patent: March 9, 2021Assignee: AltumView Systems Inc.Inventors: Zili Yi, Xing Wang, Him Wai Ng, Sami Ma, Jie Liang
