Abstract: Systems, methods, and devices associated with the precise manipulation and placement of virtual content/objects in virtual space are disclosed herein. In some embodiments, user input data associated with placement of virtual content in a virtual space can be filtered/transformed across one or more degrees of freedom of the coordinate system associated with the virtual space. The filters/transforms may add precision to placement of the virtual content. The user input data can continually be monitored to detect an indication that the virtual content is close to a target location/orientation in the virtual space, and filters/transforms may be adjusted or applied to provide the user with additional precision and control over placement of the virtual content.

Abstract: This document describes imaging and visualization systems in which the intent of a group of users in a shared space is determined and acted upon. In one aspect, a method includes identifying, for a group of users in a shared virtual space, a respective objective for each of two or more of the users in the group of users. For each of the two or more users, a determination is made, based on inputs from multiple sensors having different input modalities, a respective intent of the user. At least a portion of the multiple sensors are sensors of a device of the user that enables the user to participate in the shared virtual space. A determination is made, based on the respective intent, whether the user is performing the respective objective for the user. Output data is generated and provided based on the respective objectives respective intents.

Abstract: The present disclosure is directed to systems, methods, and devices are configured to ensure, improve, and/or verify the quality of the administration of a remote medical health or diagnostic exam. These systems, methods, and devices may improve the testing experience for the user and ensure test quality for the administered test. For example, the disclosure may enable easier transitioning between an augmented reality experience and pre-recorded video upon a failure with the augmented reality experience during the administration of a remote health or diagnostic exam.

Abstract: At-home diagnostic tests kits may be used by individuals to self-administer a diagnostic test. The diagnostic test kit can include one or more machine-readable codes on the surface of the test kit which may indicate information about the diagnostic test, such as whether a proctor is required during administration of the test. A software can be used to match a user with a proctor, and provide monitoring and quality control over the proctors performance.

Abstract: According to some aspects, a method for at-home diagnostic testing and treatment can include receiving, from a first data source, forecast information, the forecast information indicating a projected infection trend; receiving, from a second data source, a risk profile; receiving, from a third data source, a selection of one or more individuals; converting the selection of one or more individuals to a format compatible with a fourth data source; requesting, from the fourth data source, health information associated with at least one of the one or more individuals; receiving, from the fourth data source, health information of at least one of the one or more individuals; determining, for each of the one or more individuals, a risk score, wherein the risk score is based at least in part on the health information and the forecast information; and determining that a risk score of an individual meets the risk profile.

Abstract: Systems and methods for providing remotely proctored at-home health testing and diagnostics are provided herein. In particular, systems and methods for improving proctor performance by increasing accuracy and reducing proctor time are disclosed. In some embodiments, images and/or video of a patient may be enhanced to aid the proctor. In some embodiments, proctor performance may be evaluated. In some embodiments, proctor time per patient may be reduced by automating one or more steps in a proctored testing process.

Abstract: A method is described for avoiding gyroscopic singularities during attitude correction to a system, such as a spacecraft having a CMG array. The method receives a corrective torque vector ? and gimbal angle values ? for each of at least three gimbals within the CMG array. The method generates a Jacobian matrix A as a function of gimbal angle values ?. The method calculates a determinant D of Jacobian matrix A. If the determinant is not equal to zero, it is not singular, and the method calculates a gimbal rate {dot over (?)} using a pseudo-inverse steering law equation. If the determinant is equal to zero, it is singular, and the method calculates a gimbal rate {dot over (?)} using a singularity avoidance steering law equation. The gimbal rate {dot over (?)} is output and can be applied to a CMG array resulting in applied torque to a spacecraft and attitude correction.

Abstract: A device for temporarily splinting toes, especially for the treatment of hammertoes and other defective positions of toes, consisting of a tube composed of a bio-absorbable material and a guide wire. The tube has an inner diameter of d, whereas the guide wire has an external diameter D, such that D<d. The device enables contact between the ball of the toe and the floor to be reestablished.

Abstract: An arrhythmia control system and method having automatic determination of the tachycardia confirmation interval. The interval is dynamically set at the minimum of an absolute detection interval and a value calculated as a function of either average sinus interval or tachycardia cycle length or both. The continued presence or the reversion of a pathologic tachycardia can be reliably confirmed, particularly when the patient experiences an elevated heart rate due to, for example, exercise, prior to onset of the tachycardia.
