Patent number: 11771852Abstract: A droplet delivery device with a small volume drug ampoule and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The droplet delivery device is configured to facilitate the ejection of small, e.g., single use, volumes of a therapeutic agent. The droplet delivery device includes a housing, a mouthpiece, a small volume drug ampoule, an ejector mechanism, and at least one differential pressure sensor. The delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The droplet delivery device is then actuated to generate a plume of droplets having an average ejected particle diameter within the respirable size range, e.g, less than about 5-6 ?m, so as to target the pulmonary system of the user.Type: GrantFiled: November 8, 2018Date of Patent: October 3, 2023Assignee: PNEUMA RESPIRATORY, INC.Inventors: John H.

Patent number: 11756267Abstract: A method for navigating in a simulated environment is disclosed herein. A navigation device determines a search space associated with a plurality of viewpoints other than the current viewpoint in a three-dimensional (3D) space for a current viewpoint. The search space comprises a set of 3D coordinates for each of the plurality of viewpoints. The navigation device determines a field of view at the current viewpoint, which is an area associated with a viewing angle and a visible distance. The navigation device determines a target viewpoint in the search space of the current viewpoint based on the field of view at the current viewpoint. The target viewpoint is outside the area of the field of view at the current viewpoint. The navigation device causes display of a guidance user interface (UI) comprising an indicator corresponding to the target viewpoint in the field of view at the current viewpoint.Type: GrantFiled: May 23, 2022Date of Patent: September 12, 2023Assignee: Realsee (Beijing) Technology Co., Ltd.Inventors: Yiding Wang, Chengjie Li, Jie Bai, Yi Zhu
