Abstract: A smart face mask protects a user from harmful contaminants found in the user's environment. The face mask includes inlet and outlet filters to not only protect the user, but also other people within a vicinity of the user. The inlet and outlet filters include fans that promote proper air flow into and out of the mask. Air respiratory sensors provide accurate measurements of possible air contaminants. Sensors also collect data that is used to control and change fan speed operations. A mobile application controlled by the user is used to control operation of the face mask during use. Communications via short range wireless network 150s are provided between people via microphones, speakers, or earpieces. The face mask may be worn in shared spaces, indoor environments, or outdoor environments.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for adjusting physical location usage for a plurality of particular locations. Methods can include obtaining a three-dimensional (3D) representation of the given geographic area, wherein the 3D representation depicts a view of the given geographic area from a specified viewing perspective. For the given geographic area, traffic data is obtained indicating different traffic volumes during different time periods and one or more traffic characteristics. The 3D representation is segmented into a plurality of particular locations. For each particular location among the plurality of particular locations and based on the traffic data, a viewability score is determined that indicates an aggregate amount of time that the particular location is viewable by traffic passing the different locations. Physical location usage is then adjusted based on the viewability scores for the plurality of particular locations.

Abstract: Introduced here are methods, apparatuses, and systems for mitigating the contact pressure applied to a human body by the surface of an object, such as a chair, bed, or table. A pressure-mitigation apparatus can include a series of chambers whose pressure can be individually varied. When placed between a patient and a contact surface, a controller can vary the contact pressure on the human body by controllably inflating one or more chambers, deflating one or more chambers, or any combination thereof. By monitoring the pressure in each chamber over time, the controller can also gain an enhanced understanding of movement(s) performed by the human body when positioned on the pressure-mitigation apparatus.

Abstract: A system for detecting Denial-of-Service (DoS) attacks on one or more user profiles collects a number of invalid sign-on attempts on the one or more user profiles during every time interval. The system determines a number of invalid sign-on attempts on every user profile since the start of the first time interval. The system detects a first DoS attack on a particular user profile if a first number of invalid sign-on attempts on the particular user profile exceeds a single-user profile. The system detects a second DoS attack on multiple user profiles during the first time interval if the increase in the total number of invalid sign-on attempts since the last time interval exceeds a scan-level threshold number. The system detects a third DoS attack on multiple user profiles if the total number of invalid sign-on attempts detected during combined time intervals exceeds a third threshold number.

Abstract: Methods and systems for intraoperatively determining alignment parameters of a spine during a spinal surgical procedure are disclosed herein. In some embodiments, a method of intraoperatively determining an alignment parameter of a spine during a surgical procedure includes receiving initial image data of the spine including multiple vertebrae and identifying a geometric feature associated with each vertebra in the initial image data. The geometric features each have a pose in the initial image data and characterize a three-dimensional (3D) shape of the associated vertebra. The method further comprises receiving intraoperative image data of the spine and registering the initial image data to the intraoperative image data. The method can then update the pose of each geometric feature based on the registration and the intraoperative image data, and determine the alignment parameter based on the updated poses of the geometric features associated with two or more of the vertebrae.

Abstract: Control systems for liquid lenses can use feedback control using one or more measured parameters indicative of a position of the fluid interface in the liquid lens. Capacitance between a fluid and an electrode in the liquid lens can vary depending on the position of the fluid interface. Current mirrors can be used for making measurements indicative of the capacitance and/or the fluid interface position. The liquid lens can be calibrated using the measurements indicative of capacitance and/or fluid interface position as the voltage is driven across an operational range. A control system can use pulse width modulation (PWM) for driving a liquid lens, and a carrier frequency for the PWM signals can be varied to control power consumption in the liquid lens. The slew rate can be adjustable to control power consumption in the liquid lens.

Abstract: Grain size of a deliverable metal product can be improved by pre-setting recrystallization-suppressing dispersoids during casting. The outer regions of a direct chill cast embryonic ingot can undergo reheating before casting is complete. Through unique wiper placement and/or other reheating techniques, the temperature of the ingot can be permitted to reheat (e.g., up to approximately 410° C. to approximately 420° C.), allowing dispersoids to form. Stirring and/or agitation of the molten sump can facilitate formation of a deeper sump and desirably fine grain size as-cast. The formation of dispersoids during and/or immediately after casting can pin the grain boundaries at the desirably fine grain size, encouraging the same grain sizes even after a later recrystallization and/or solutionizing step.
