Publication number: 20200401136Abstract: An autonomous control system generates synthetic data that reflect simulated environments. Specifically, the synthetic data is a representation of sensor data of the simulated environment from the perspective of one or more sensors. The system generates synthetic data by introducing one or more simulated modifications to sensor data captured by the sensors or by simulating the sensor data for a virtual environment. The autonomous control system uses the synthetic data to train computer models for various detection and control algorithms. In general, this allows autonomous control systems to augment training data to improve performance of computer models, simulate scenarios that are not included in existing training data, and/or train computer models that remove unwanted effects or occlusions from sensor data of the environment.Type: ApplicationFiled: June 8, 2020Publication date: December 24, 2020Inventors: Forrest Nelson Iandola, Donald Benton MacMillen, Anting Shen, Harsimran Singh Sidhu, Paras Jagdish Jain

Publication number: 20200401160Abstract: A convoy of trucks can save fuel by drafting, following at small vehicle separations. Autonomous vehicles can follow much closer than human driven vehicles, in the sub meter spacing. A problem with this is that it can create a moving wall that blocks other traffic. For example, a convoy in the right lane of a two-lane highway could block a car in the left lane from exiting. If there was sufficient space in between the convoying trucks, the car could merge in between two trucks and then exit. Unfortunately, this larger spacing diminishes the benefits of drafting. The present invention involves a system for convoying autonomous vehicles that changes separation distances depending on the behavior of the surrounding autonomous vehicles comprising two or more autonomous systems, a set of sensors that allows it to sense its environments, other autonomous vehicles, their position, and their velocities and a control system that uses the location of the surrounding autonomous vehicles to adjust the convoy distance.Type: ApplicationFiled: June 20, 2019Publication date: December 24, 2020Inventor: Alberto Daniel Lacaze

Publication number: 20200401178Abstract: The clock generator is provided and includes a phase detector, a voltage generator, a voltage-to-current converter, and an oscillation circuit. The voltage generator generates a control voltage. The voltage-to-current converter converts the control voltage into an internal current having a level based on a resistance value of a resistor circuit, the resistance value set based on first control information. The oscillation circuit generates a output clock having a frequency based on the level of the internal current and a capacitance value of a capacitor circuit, the capacitance value set based on second control information. The clock generator maintains a frequency value and varies jitter characteristics of the output clock in response to the first control information and the second control information.Type: ApplicationFiled: December 23, 2019Publication date: December 24, 2020Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Sangdon Jung, Jaehong Jung, Seunghyun Oh, Kyungmin Lee

Publication number: 20200401179Abstract: A method of automatically constructing a hierarchical clock tree for an integrated circuit may include constructing a global clock tree on a first level based on first-level constraints, pushing the global clock tree to partitions on a second level, and generating second-level constraints for the partitions on the second level. The second-level constraints may be included in configuration files that may be generated for the partitions on the second level. The first-level constraints may be included in a first-level configuration file that is user-modifiable. The second-level constraints may include information for replicating multiple instantiated partitions on the second level. The method may further include modifying terminal names and/or configurations after pushdown. The method may further include creating infrastructure to analyze timing of the global clock tree.Type: ApplicationFiled: October 25, 2019Publication date: December 24, 2020Inventors: Sridhar SUBRAMANIAM, Hongda LU, Kok-Hoong CHIU

Publication number: 20200401180Abstract: A phase detection circuit may include an edge trigger circuit, a strobe generation circuit and a phase detector. The edge trigger circuit generates a falling clock signal and a rising clock signal based on a reference clock signal and a target clock signal. The strobe generation circuit generates a falling strobe signal and a rising strobe signal having pulse widths varying based on a phase relationship between the reference clock signal and the target clock signal. The phase detector generates a phase detection signal based on the falling clock signal, the rising clock signal, the falling strobe signal and the rising strobe signal.Type: ApplicationFiled: December 6, 2019Publication date: December 24, 2020Applicant: SK hynix Inc.Inventor: Gyu Tae PARK

Publication number: 20200401181Abstract: In one embodiment, a method includes receiving, from a controller, a data packet including (1) a plurality of samples each corresponding to measurements from a motion sensor and (2) a timestamp corresponding to a measurement time of one of the samples as measured by a clock of the controller; determining, based on the timestamp, an estimated measurement time relative to a local clock for each of the plurality of samples that is not associated with the timestamp; and converting each of the timestamp and the estimated measurement times to a corresponding synchronization time using a learned relationship relating the clock of the controller and the local clock. The learned relationship is iteratively learned based on previously received data packets from the controller. The synchronization time associated with each of the plurality of samples represents an estimated time, relative to the local clock, at which the sample was measured.Type: ApplicationFiled: August 31, 2020Publication date: December 24, 2020Inventors: Boyang Zhang, Adrian Brian Ratter, Chengyuan Yan, Jack Hood Profit, JR., Paul Austin Buckley

Publication number: 20200401182Abstract: Transitioning between a high-resolution input mode, such as a mouse-based interface, and a low-resolution input mode, such as a touch-based interface, is described. A change of orientation of a touch screen between a first orientation and a second orientation is detected. Transitioning between the two input modes and corresponding user interfaces (UIs) is based on the detected change of orientation. A change of orientation can be detected with one or more sensors, such as an accelerometer, position sensors, etc. Transitioning from one mode to another can include modifying an item displayed in the UI of the one mode into a corresponding item displayed in the UI of the other mode. The modifying can include enlarging/reducing, obscuring/unobscuring, moving, etc. For example, an item can be obscured by the visual effect of sliding it off of the screen.Type: ApplicationFiled: July 6, 2020Publication date: December 24, 2020Inventor: Paul COSTA
