Abstract: A locking assembly (10) for a medical device (1), the device (1) adapted to adjust the position of an upper teeth engagement member to a lower teeth engagement member, the device (1) having a plate, an elongate recess and a block slidable along said recess to adjust the position of the members relative to each other; the locking assembly (10) including: a screw having an elongate shaft having a thread extending substantially towards one end and a head at the other end, the thread adapted to engage the block, the head having at least one engagement member; and a cap having a corresponding at least one engagement member in use to lock the engagement members together to inhibit said screw from rotating in said block.

Abstract: A method and a system for counteracting model drift in a Latent Dirichlet Allocation (LDA) model by maintaining freshness and accuracy in the LDA model by leveraging LDA classification and vector algebra to detect potential degradations are provided. The method includes: receiving a first corpus that includes a first set of textual data; generating a first set of topics by applying a first LDA model to the first corpus; generating, for each topic, a corresponding vector of words with associated weights; measuring a cosine similarity of each topic with respect to a second set of topics that is associated with a second LDA model; using the measured cosine similarities to determine a topic match entropy between the first LDA model and the second LDA model; and when the topic match entropy exceeds a predetermined threshold, determining that the first LDA model has drifted and requires retraining.

Abstract: An aspect of the present disclosure relates to an intra-oral device. The intra-oral device comprises a lower arch component and an upper arch component, wherein the lower arch component is configured to be advanced relative to the upper arch component. The intra-oral device further comprises sensors configured for detecting characteristics of a patient, wherein the sensors are disposed in the upper arch component or the lower arch component, wherein the characteristics comprise indicators of sleep apnea on the patient and the advancement of the lower arch component relative to the upper arch component. The intra-oral device further comprises a processor in communication with the sensors to receive the detected characteristics, wherein the detected characteristics are used to determine efficacy of the intra-oral device in reducing the sleep apnea of the patient.
