Publication number: 20230245452Abstract: Embodiments of adaptive multi-modal event detection are disclosed herein. In one example, sensor data captured by multiple sensors is received, and an inconsistency among the sensors is detected based on performing event detection on the sensor data. An external environment of the sensors is detected based on the sensor data, and one or more configuration parameter(s) for event detection are adjusted based on the external environment of the sensors. Event detection is then performed on the sensor data based on the adjusted configuration parameter(s).Type: ApplicationFiled: April 6, 2023Publication date: August 3, 2023Applicant: Intel CorporationInventors: Say Chuan Tan, Mee Sim Lai, Ying Wei Liew, Chien Chern Yew, Kuan Heng Lee, Nicolas C.

Patent number: 10820029Abstract: A method and apparatus for alerting groups of user devices to similar video content of interest based on role. The method includes providing a first video to groups of user devices, each having an associated user role, receiving viewing metrics indicative of levels of viewing interest for the first video from a first group of user devices associated with a particular user role, and when a level of viewing interest is above a predetermined threshold, classifying one or more corresponding first video frames of the first video as frames of interest. The method further includes receiving a second video, determining, using the frames of interest, that video content of the second video is of interest to a second group of user devices having the particular user role, and providing an alert to the second group of user devices.Type: GrantFiled: October 24, 2018Date of Patent: October 27, 2020Assignee: MOTOROLA SOLUTIONS, INC.Inventors: Kuan Heng Lee, Eng Wiang Chan, Peng Khoon Cheah, Mern Keat Lee, Kok Khian Ng, Prebesh Pavithran, Anil Kumar Vadlamudi

Publication number: 20200304708Abstract: A method and apparatus for acquiring an image is provided herein. During operation a determination is made that a user is intending to tag an object through pointing a finger at the object. In response, a pre-buffer is accessed, and an image of the object is selected from the pre-buffer that is absent the user's hand. Once the image has been selected, the image can be forwarded to other users.Type: ApplicationFiled: March 18, 2019Publication date: September 24, 2020Inventors: KUAN HENG LEE, TIH HUANG YEOH, ALWIN SONG GEN OOI, ANIL KUMAR VADLAMUDI, LEE SUN OOI, MOH LIM SIM

Patent number: 10175559Abstract: A camera flash system and method for the same. In one example, the system includes a camera including an image sensor, a plurality of lights, and an electronic processor. The camera is configured to capture an image frame. Each of the lights is configured to illuminate a region within the image frame. The electronic processor is configured to capture via the camera, while modulating an output of the plurality of lights, a first image frame and determine, using the image sensor, an object of interest within the first image frame. The electronic processor is further configured to identify a region of interest in which the object of interest is located based on the first image frame, identify, based on the region of interest, a subset of lights from the plurality of lights, and activate the subset of lights.Type: GrantFiled: November 3, 2017Date of Patent: January 8, 2019Assignee: MOTOROLA SOLUTIONS, INC.Inventors: Kok Khian Ng, Daniel Grobe Sachs, Kuan Heng Lee, Mern Keat Lee

Patent number: 9977429Abstract: Methods and systems of positioning a drone including a camera. One method includes generating, from a first image capture position of the drone, a first image or video having a first field of view. The method further includes determining a plurality of regions of interest, each of the plurality of regions of interest located within a predetermined area and having an associated priority. The method further includes determining a second image capture position different from the first image capture position for the drone as a function of the associated priority and a viewing distance of the camera. The method further includes generating a command for the drone to move to the second image capture position. The method further includes moving the drone based on the command. The method further includes generating, from the second image capture position, a second image or video having a second field of view.Type: GrantFiled: May 4, 2016Date of Patent: May 22, 2018Assignee: MOTOROLA SOLUTIONS, INC.Inventors: Kuan Heng Lee, Li Poh Chen, Su Lin Koay, Yen Nee Lee, Shervin Sabripour, Soo Fong Tan, Yew Leong Wong
