Patent number: 11295140Abstract: A camera system may automatically identify high frequency motion regions in a field of view of the camera system. Analysis of motion events detected at different regions of a scene in the field of view, may be performed. Similar events frequently occurring at a certain region may be recorded/accumulated and compared to a threshold. Regions with high frequency activity may be determined and a user may be notified. If the user is not interested in events within the high activity regions, the regions may be ignored and notifications to the user may cease. The camera system may determine specific actions/events occurring in a region, such as a person approaching or leaving a home.Type: GrantFiled: March 14, 2019Date of Patent: April 5, 2022Assignee: COMCAST CABLE COMMUNICATIONS, LLCInventors: Hongcheng Wang, Rui Min, Hong Li, Ruichi Yu

Publication number: 20210382939Abstract: Methods and systems for more efficient analyses of and response to voice commands and queries are provided. The system may be configured to receive one or more of audio files corresponding to a voice query and determine, for each of the audio files, whether the audio file is a first type of audio file capable of being processed based on a characteristic of the audio file or a second type of audio file that cannot, and may require further processing in order to recognize the voice query associated with the audio file. The system may process each of the first type of audio files and respond to the associated voice queries. The system may also determine a priority for each of the second type of audio files for further processing of the second type of audio files.Type: ApplicationFiled: August 25, 2021Publication date: December 9, 2021Inventors: Rui Min, Hongcheng Wang

Publication number: 20210325201Abstract: A voice enabled device can assist a computing device, such as a server, in processing/analyzing a voice input. The voice enabled device can initiate a network communication session and transmit the voice input to the computing device. The computing device can classify the voice input as a type of communication session (e.g., conversation, etc. . . . ). Based on the type of communication session, the computing device can either remain in communication with the voice enabled device and continue to process voice input or terminate the communication after instructing the voice enabled device to process the voice input.Type: ApplicationFiled: January 28, 2021Publication date: October 21, 2021Inventors: Rui Min, Hongcheng Wang, Vamsi Potluru, Vijayendra Ghadge, Raul Guerra Paredes

Publication number: 20210311989Abstract: An audio file associated with a user voice query may be received at a user device. The audio file may be compared to a plurality of references, such as cache entries, corresponding to a plurality of other voice queries. Based on a determination that the voice query corresponds to one of the references, an operation associated with the voice query may be executed. An indication may be received that the operation was not an intended operation associated with the voice query. Based on receiving this indication, the incorrectly identified operation, associated reference, e.g., voice query, may be disabled for the user or the device. However, the cache entry may remain enabled for one or more of a plurality of other devices.Type: ApplicationFiled: April 3, 2020Publication date: October 7, 2021Inventors: Rui Min, Stefan Deichmann, Hongcheng Wang

Publication number: 20210117470Abstract: A device may be configured to determine whether an audio file is a first type of audio file that is capable of being processed to recognize the voice query based on a characteristic of the audio file itself or a second type of audio file that may require speech recognition processing in order to recognize the voice query associated with the audio file. In determining whether the audio file is a first type of audio file or a second type of audio file, a query filter associated with the device may be configured to access one or more guidance queries. Using the one or more guidance queries, the device may classify the audio file as a first type of audio file or a second type of audio file based on receiving only a portion of the audio file, thereby improving the speed at which the audio file can be processed.Type: ApplicationFiled: October 21, 2019Publication date: April 22, 2021Inventors: Rui MIN, Hongcheng WANG

Publication number: 20200279565Abstract: A cache associated with a voice recognition engine may be configured to receive an audio file corresponding to a voice query. The voice query may be received by the voice recognition engine from a user device in response to receipt of the voice query by the user device at the user device. The cache may be configured to determine an audio fingerprint based on the audio file and to determine whether the audio fingerprint corresponds to one of a plurality of audio transcriptions stored in the cache. The audio transcriptions may correspond to popular voice queries received at the voice recognition engine and processed by a server capable of performing automated speech recognition. In response to determining that the audio fingerprint corresponds to a given one of the stored audio transcriptions, the audio file may be processed based on the stored audio transcription.Type: ApplicationFiled: March 10, 2020Publication date: September 3, 2020Inventors: Rui Min, Hongcheng Wang

Publication number: 20200273448Abstract: Methods, systems, and apparatuses for predicting an end of a command in a voice recognition input are described herein. The system may receive data comprising a voice input. The system may receive a signal comprising a voice input. The system may detect, in the voice input, data that is associated with a first portion of a command. The system may predict, based on the first portion and while the voice input is being received, a second portion of the command. The prediction may be generated by a machine learning algorithm that is trained based at least in part on historical data comprising user input data. The system may cause execution of the command, based on the first portion and the predicted second portion, prior to an end of the voice input.Type: ApplicationFiled: February 27, 2019Publication date: August 27, 2020Inventors: Rui Min, Hongcheng Wang

Patent number: 10444500Abstract: A projection screen of a head-up display has a projection surface and a back surface opposite to the projection surface. The projection surface is used for receiving an image beam projected by an image projection component and reflecting part of the image beam. The projection screen includes a photochromic layer disposed on the transmission path of the image beam. When an ambient light irradiates the back surface of the projection screen, the transmittance of the photochromic layer decreases as the intensity of the ambient light increases.Type: GrantFiled: August 13, 2018Date of Patent: October 15, 2019Assignee: SICHUAN LONGHUA FILM CO., LTDInventors: Rui-Min Diao, Yao-Chang Wang
