Publication number: 20240080444Abstract: Bitrate-adaptive segmentation is performed for transcoding a video stream uploaded to an online video platform for hosting and later playback to platform users. The video stream is segmented into chunks based on prediction-based bit costs determined for frames of the video stream rather than based on scene changes detected within the video stream. The bitrate-adaptive segmentation includes determining inter-prediction bit costs and intra-prediction bit costs for frames of the video stream based on information indicated within a pass log based on a first pass encoding of the video stream, determining chunk boundaries for segmenting the video stream into a chunk based on the inter-prediction bit costs and the intra-prediction bit costs for the frames, and transcoding the chunk to produce a transcoded video stream.Type: ApplicationFiled: November 13, 2023Publication date: March 7, 2024Inventors: Di Chen, Sam John

Patent number: 11757299Abstract: Methods and system include power harvesting with process and device monitoring. A power management system including a solar cell can be integrated with a display panel into a common housing. A capacitor and a rechargeable battery connected to the power management system can receive power from the solar cell and provide electrical power, first from the capacitor and then second from the rechargeable battery, to electronic components including the display engaged in monitoring processes and devices deployed in isolated locations. Electronics can include a microprocessor programmed to provide collected data display on the display panel and wireless transmission to a remote monitoring station. A rotatable stem operated by a step-motor and connected to the common housing can orient the integrated display and solar cell towards sunlight according to an internal time clock synchronizing movement of the display panel via a step motor and thereby maximize harvesting of electrical energy.Type: GrantFiled: August 16, 2019Date of Patent: September 12, 2023Assignee: Honeywell International Inc.Inventors: Sam Chen, Bin Sai

Patent number: 11668116Abstract: A door handle set includes a handle assembly having a primary lock and having a handle rotatable about a primary rotational axis. A latch bolt assembly has a latch bolt. The latch bolt assembly is operatively coupled to the handle assembly, wherein a rotation of the handle results in a linear translation of the latch bolt. A supplemental lock has a second axis parallel to, and spaced apart from, the primary rotational axis. The supplemental lock has an actuator that is operable relative to the second axis. The supplemental lock is configured to selectively block the rotation of the handle regardless of the locking state of the primary lock.Type: GrantFiled: December 5, 2017Date of Patent: June 6, 2023Assignee: dormakaba USA Inc.Inventors: (Steven) Ming-Che Chen, (Sam Chen) Po-Yang Chen, (Newman Lai) Cheng-Wen Lai Lai, (Kate) Kai-Ting Tung, Justin Crotzer, Brandon Faulkner

Publication number: 20150308246Abstract: A process for hydrocarbon recovery from a hydrocarbon-bearing formation utilizing an injection well for the injection of a mobilizing and displacing fluid, such as steam, into the formation and a production well, spaced from the injection well, and through which hydrocarbon is recovered. The process includes injecting a surfactant and a gas into the production well for a first period of time to thereby emplace or form foam to an extent sufficient to modify the path of flow in an inter-well region between the injection well and the production well and in an area spaced from the inter-well region of the reservoir, which area is in fluid communication with at least one of the injection well and the production well. The process also includes injecting fluid into the injection well to cause the flow of hydrocarbon in the formation and recovering the hydrocarbon through the production well.Type: ApplicationFiled: April 28, 2015Publication date: October 29, 2015Inventors: Sam Chen, Subodh Gupta, Alvin Winestock
