Patent number: 11645675Abstract: An online system trains machine learning models that, when applied to gathered sensor data, determines personal characteristics (e.g., age, gender, height) of an individual in a non-intrusive manner. Specifically, the online system trains a first machine learning model that analyzes sensor data gathered from a client device associated with the individual. The first machine learning model determines whether a trigger event, such as whether the individual is walking, is currently occurring. A second machine learning model trained by the online system analyzes sensor data corresponding to the trigger event to identify the personal characteristics of the walking individual.Type: GrantFiled: March 31, 2017Date of Patent: May 9, 2023Assignee: AdsWizz Inc.Inventors: Bruno Nieuwenhuys, Victor Mocioiu, Sergiu Alexandrescu, Ciprian Caba, Alexandru Cotiga

Patent number: 11459133Abstract: A method is provided for realigning or relieving mechanical stress in a spacecraft frame. The process includes providing a spacecraft which includes at least two frame subsections connected by a mechanical connector. The mechanical connector provides both a soft dock connection which mechanically connects the two frame subsections but allows relative movement between the two frame sections and a hard dock connection which mechanically connects the two frame subsections but does not allow relative movement between the two frame sections. Once in space, a controller causes the mechanical connector to transition from a hard dock connection to a soft dock connection, which is maintained for a predetermined time period to realign or relieve stress within the spacecraft frame. Thereafter, the controller causes the mechanical connector to transition from the soft dock connection back to the hard dock connection.Type: GrantFiled: May 8, 2019Date of Patent: October 4, 2022Assignee: NOVAWURKS, INC.Inventor: Talbot Jaeger
