Publication number: 20260162553Abstract: The present invention comprises novel processes to facilitate learning through automated, bidirectional, multimodal, and personalized question and answer practice. Content creation is accelerated through an automated extraction pipeline, lowering barrier-to-entry in domains with sufficient documentation. To practice the material, Learners converse with an AI Examiner which offers personalized, dynamic follow-up responses and evaluation. The Examiner may assume the role of an instructor or a student, either posing questions or attempting to answer them, with the Learner adopting the opposite role. Other configuration settings for the Examiner include input/output modality and grading stringency. With these options available, a Learner can rapidly iterate through different postures and means of practice and learning, compressing the time required to master knowledge and related question and answer skills.Type: ApplicationFiled: November 18, 2025Publication date: June 11, 2026Applicant: Call SimulatorInventors: Luke Van Popering, Eric Sharkey, Jeremy Quinto, Michael LaFortune, David Lawson

Patent number: 12599177Abstract: A mouthpiece assembly for an inhalation device including a replaceable substrate component and a replaceable substrate component therefor. The mouthpiece assembly includes a mouthpiece which is essentially a hollow tube within which fluid flow can occur along a substantially longitudinal axis thereof. Within the mouthpiece, a cavity region is formed which is adapted to receive and locate the substantially planar elongated substrate component, such that it interacts with the fluid flow when occurring. The substrate component includes a substrate which can be excited sufficiently to cause aerosolization, and the substrate is fixedly mounted within the substrate component in an orientation and location whereby a channel formation or a conduit of the substrate component at least partially coincides with the cavity region, and thus the surface of the substrate in that cavity region is exposed to, and may be entrained within, whatever fluid may be flowing in that channel or conduit.Type: GrantFiled: January 3, 2024Date of Patent: April 14, 2026Assignee: Ventus Medical LimitedInventors: David Lawson, Gethin Griffith, Mark Dignum

Patent number: 10115842Abstract: Embodiments of the present disclosure are directed to optical packages having a package body that includes a light protection coating on at least one surface of a transparent material. The light protection coating includes one or more openings to allow light to be transmitted to the optical device within the package body. In one embodiment, the light protection coating and the openings allow substantially perpendicular radiation to be directed to the optical device within the package body. In one exemplary embodiment the light protection coating is located on an outer surface of the transparent material. In another embodiment, the light protection coating is located on an inner surface of the transparent material inside of the package body.Type: GrantFiled: November 2, 2017Date of Patent: October 30, 2018Assignees: STMICROELECTRONICS PTE LTD., STMICROELECTRONICS R&D LIMITEDInventors: Yonggang Jin, David Lawson, Colin Campbell, Anandan Ramasamy

Patent number: 10089790Abstract: A virtual reality display system that generates display images in two phases: the first phase renders images based on a predicted pose at the time the display will be updated; the second phase re-predicts the pose using recent sensor data, and corrects the images based on changes since the initial prediction. The second phase may be delayed so that it occurs just in time for a display update cycle, to ensure that sensor data is as accurate as possible for the revised pose prediction. Pose prediction may extrapolate sensor data by integrating differential equations of motion. It may incorporate biomechanical models of the user, which may be learned by prompting the user to perform specific movements. Pose prediction may take into account a user's tendency to look towards regions of interest. Multiple parallel pose predictions may be made to reflect uncertainty in the user's movement.Type: GrantFiled: September 28, 2016Date of Patent: October 2, 2018Assignee: Ariadne's Thread (USA), Inc.Inventors: David Lawson, Adam Li
