Abstract: A secondary battery is provided for cycling between a charged and a discharged state, the secondary battery including a battery enclosure, an electrode assembly, carrier ions, a non-aqueous liquid electrolyte within the battery enclosure, and a set of electrode constraints. The set of electrode constraints includes a primary constraint system having first and second primary growth constraints and at least one primary connecting member, the first and second primary growth constraints separated from each other in the longitudinal direction, wherein the primary constraint array restrains growth of the electrode assembly in the longitudinal direction such that any increase in the Feret diameter of the electrode assembly in the longitudinal direction over 20 consecutive cycles of the secondary battery is less than 20%.

Abstract: An augmented reality (AR) device can be configured to generate a virtual representation of a user's physical environment. The AR device can capture images of the user's physical environment to generate or identify a user's location. The AR device can project graphics at designated locations within the user's environment to guide the user to capture images of the user's physical environment. The AR device can provide visual, audible, or haptic guidance to direct the user of the AR device to explore the user's environment.

Abstract: Driving simulations may be generated based on driving log data and used to validate autonomous vehicle safety systems. A driving simulation system may receive driving log data from autonomous vehicles and determine events which caused a vehicle to diverge from a planned trajectory. Driving simulations may be generated based on the driving log data, and executed using a simulated vehicle that follows the initial planned trajectory of the autonomous vehicle. The driving simulations may be analyzed to detect potential collisions and near misses, and to determine success conditions for the behaviors of vehicle safety systems. Driving simulations and associated success conditions may be aggregated and used in validation suites for vehicle controllers and/or vehicle safety systems, thereby providing more comprehensive and robust autonomous vehicle validation based on real-world driving scenarios.

Abstract: A system for robotic surgery makes use of an end-effector which has been configured so that a drill connected thereto is guided in its trajectory and limited in its advancement into an associated anatomical feature by a drill guide. The drill guide may be adjusted manually to engage a corresponding surface of the drill after its advancement by a pre-selected amount. The drill guide likewise includes features to guide the drill during trajectories having oblique angles relative to the surface of the anatomical feature associated with the medical procedure.

Abstract: A method for controlling brake pressure during a shift of a vehicle out of park may include determining that a first status condition is met when the vehicle is in park with an electric parking brake applied, determining that a second status condition is met when the vehicle is not moving, responsive to detecting a shift of the vehicle out of park when the first and second status conditions are both met, directing a build-up of brake pressure until a brake pressure target is reached, and holding the brake pressure at the brake pressure target until a release condition is met.

Abstract: A cable retraction system, useful at least in vital signs monitoring systems, rolls sensors cables and tubes on rotary spring spools, inside a protective enclosure, for storage. The cables and tubes along with the sensors can easily be pulled out for use and then retracted back into the enclosure as required. This eliminates tangled cables and tubes and provides protection for the sensors by not being on dangling long cables when not in use.

Abstract: Systems and methods for displaying a cursor and a focus indicator associated with real or virtual objects in a virtual, augmented, or mixed reality environment by a wearable display device are disclosed. The system can determine a spatial relationship between a user-movable cursor and a target object within the environment. The system may render a focus indicator (e.g., a halo, shading, or highlighting) around or adjacent objects that are near the cursor. The focus indicator may be emphasized in directions closer to the cursor and deemphasized in directions farther from the cursor. When the cursor overlaps with a target object, the system can render the object in front of the cursor (or not render the cursor at all), so the object is not occluded by the cursor. The cursor and focus indicator can provide the user with positional feedback and help the user navigate among objects in the environment.

Abstract: A method of simulating an emergency response training scenario to users in different locations, including customizing a scenario, initiating a game state having a threat level and a time remaining, assigning a role to each of a plurality of users wherein each of the users uses a device, assigning digital assets within the scenario to each of the users, displaying an introduction sequence, initiating an incident and simultaneously notifying a first group of at least two users, logging and scoring a chosen response from the possible responses compared to a scoring system, updating the game state whereby the threat level is raised or lowered and the time remaining is increased or decreased, triggering another event to at least two of the plurality of users, and communicating a score calculated in the logging and scoring step to at least one user on one of the at least one client device.

Abstract: Systems and methods for displaying a group of virtual objects and a scrollbar in a virtual, augmented, or mixed reality environment are disclosed. The group of virtual objects can be scrolled, and a virtual control panel can be displayed indicating objects that are upcoming in the scroll.
