  • Publication number: 20260162553
    Abstract: 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.

  • Patent number: 12599177
    Abstract: 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.

  • Patent number: 12588698
    Abstract: Nicotine-containing formulations for electric/electronic nicotine delivery systems are disclosed, containing both nicotine at relatively much higher concentrations, typically at least 25% by weight of total formulation weight, w/w, and in many cases as much as 40-50% w/w, than is typical for conventional nicotine containing formulations, which only contain about 2-4% w/w nicotine. The formulations also include a biologically and pharmaceutically acceptable mono- or di-carboxylic organic acid, such as benzoic acid, salicylic acid and most preferably lactic acid also at relatively high w/w concentrations.

  • Patent number: 10952467
    Abstract: An inhalation device includes a mouthpiece and a heater having a rigid planar substrate which supports at least one resistive element portion applied over a first region of at least one surface of the substrate, and a pair of contacts each connected to the at least one resistive element portion at one end of the contacts and applied over a second region of the at least one surface of the substrate. The substrate supports an aerosolizable composition deposited on the substrate above the resistive element portion of the heater. The mouthpiece has at least a fluid inlet and a fluid outlet proximate rear and front ends thereof respectively. The heater is disposed within the mouthpiece with at least portions of the contacts being both exposed and accessible so that an electrical connection can be readily achieved when the rear end of the mouthpiece is connected to the inhalation device.

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.

  • Patent number: 10089790
    Abstract: 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.

  • Patent number: 8995654
    Abstract: A method for sending encrypted data in response to a request for an I/O operation. The method includes the steps of requesting a data encryption key, the request including one or more identifiers unique to the I/O operation; receiving a data encryption key attached with a first key use fingerprint, independently generating a second key use fingerprint in response to the one or more identifiers; comparing the first and the second key use fingerprints; and if the first key use fingerprint matches the second key use fingerprint, using the data encryption key to encrypt the data to be sent. In one embodiment, the one or more identifiers include at least one of a target identifier, a LUN identifier, and a LBA range identifier.
