Patent number: 11833661Abstract: Utilization of past dynamics sample(s), that reflect past contact physics information, in training and/or utilizing a neural network model. The neural network model represents a learned value function (e.g., a Q-value function) and that, when trained, can be used in selecting a sequence of robotic actions to implement in robotic manipulation (e.g., pushing) of an object by a robot. In various implementations, a past dynamics sample for an episode of robotic manipulation can include at least two past images from the episode, as well as one or more past force sensor readings that temporally correspond to the past images from the episode.Type: GrantFiled: October 31, 2021Date of Patent: December 5, 2023Assignee: GOOGLE LLCInventors: Zhuo Xu, Wenhao Yu, Alexander Herzog, Wenlong Lu, Chuyuan Fu, Yunfei Bai, C.

Publication number: 20230375793Abstract: An apparatus includes a pluggable optical module having a fiber connector, an optical module, a fiber harness, and an edge connector. The fiber connector optically couples to an optical fiber cable. The optical module includes a photonic integrated circuit having a first surface at which optical couplers are provided. The fiber harness optically couples the fiber connector and the first surface, and includes optical fibers and an optical fiber connector that optically couples the optical fibers to the first surface. The optical fiber connector includes a 2D arrangement of fiber ports that in combination with the optical couplers enable light signals to be transmitted between the photonic integrated circuit and the optical fibers. The edge connector includes conductive pads that electrically couple to conductive pads of a receptacle when the edge connector is mated with the receptacle. The conductive pads of the edge connector are electrically coupled to the optical module.Type: ApplicationFiled: March 3, 2023Publication date: November 23, 2023Inventors: Peter Johannes Winzer, Dan Harding, Karen Liu, Mark Demers

Patent number: 11608641Abstract: In a method for recycling energy from stairs, a step platform is moveable between an upper and lower position. An energy storage device, coupled to the platform, stores energy when a downward force is applied thereto, causing the step platform to move to the lower position. The energy storage device (also releases stored energy as the step platform moves from to the upper position. A controllable locking mechanism (locks the step platform in the lower position when the downward force has caused the step platform to move into the lower position. A sensor determines when a downward force has been applied to the next higher step platform. A controller signals the controllable locking mechanism to unlock the step platform when the step platform is in the lower position, and when the downward force has been applied to the next higher step platform.Type: GrantFiled: April 13, 2021Date of Patent: March 21, 2023Assignees: Georgia Tech Research Corporation, Emory UniversityInventors: Cheng-Yun Karen Liu, Sehoon Ha, Yun Seong Song, Lena Ting

Patent number: 11435603Abstract: A thin film polymer device including a waveguide core surrounded by dielectric material positioned on a platform. The core has a passive input portion and a passive output portion joined by a necked down active portion. A layer of EO polymer material positioned on the dielectric material overlying the active portion of the core and the core, the EO polymer, and the dielectric material all having refractive indices with the refractive index of the EO polymer being higher than the refractive index of the dielectric material. Light progressing through the core from the passive input portion to the passive output portion transitions to the layer of EO polymer material as it enters the necked down active portion and transitions back to the core as it leaves the necked down active portion.Type: GrantFiled: October 14, 2020Date of Patent: September 6, 2022Assignee: LIGHTWAVE LOGIC INC.Inventors: Frederick J. Leonberger, Karen Liu, Michael Lebby

Patent number: 11372630Abstract: Efficient immutable syntax representation with parent pointers under incremental change is enabled by creating a data structure comprising at least one tree structure that allows both upward and downward references in the tree and a tree structure that is immutable (read-only), and allows parts of itself to be re-used in other data structures. The data structure described enables tools to search and target particular sub trees. The fragment of the tree representing the targeted sub tree is produced as it is used. The rest of the tree is not produced. The read-only tree retains relative information, allowing it to be reassembled and shared.Type: GrantFiled: February 17, 2020Date of Patent: June 28, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Matthew J. Warren, Mads Torgersen, Renaud Paquay, Neal M. Gafter, Jared Parsons, David N. Schach, Aleksey V. Tsingauz, Peter Golde, Kevin Andrew Pilch, Karen Liu
