Abstract: A low-power system-on-chip includes an originating controller, a fabric, and a power controller. The originating controller is configured to initiate a memory transaction request including a source address. The fabric includes an arbiter configured to receive the memory transaction request and determine a first memory device associated with the memory transaction request. The power controller is configured to selectively change a first memory bank of the first memory device from a first power mode to a second power mode based at least in part on the source address. The fabric is configured to perform a memory operation by (a) receiving stored data from memory storage locations corresponding to the source address when the memory transaction request includes a read request, and (b) sending data included in the memory transaction request to the memory storage locations when the memory transaction request includes a program or a write request.

Abstract: An expandable interbody fusion device and an associated instrument for inserting the device into an intervertebral disc space, expanding the device and for use in delivering graft material into the device once expanded in the disc space. The device is small enough to fit through Kambin's triangle yet is capable of expanding both in the vertical direction to accommodate spinal lordosis and in the lateral direction to provide sufficient structural support for opposing vertebral bodies laterally within the disc space. A process of forming textured top and bottom surfaces of the device by initially laser ablating each surface with a nano-second pulsed laser followed by laser ablating those surfaces with a femto-second pulsed laser.

Abstract: Various technologies described herein relate to routing an autonomous vehicle based upon likelihood of interacting with a disruptive third-party vehicle. A computing system receives an origin location of an autonomous vehicle and a destination location of the autonomous vehicle. The computing system identifies a route for the autonomous vehicle to take based upon output of a computer-implemented model. The computer-implemented model is generated based upon labeled data that is indicative of observed instances of a disruptive third-party vehicle exhibiting behavior that impacts operation of an autonomous vehicle. The output of the computer-implemented model is a score that is indicative of a likelihood that the disruptive third-party vehicle will be traveling through a geographic location along a candidate route at a certain time. The score is used in part to identify the route from amongst a plurality of candidate routes. The autonomous vehicle then travels along the route.

Abstract: Apparatus and devices for adding an additional spinal construct in a patient are disclosed. In one arrangement the additional spinal construct extends an existing spinal construct ipsilaterally with an inline rod connector in a minimally invasive or preferably, percutaneous procedure. In another arrangement, the ipsilateral extension of an existing spinal construct uses an offset rod connector for receiving an additional spinal rod that may be placed interiorly or exteriorly of the existing spinal construct.

Abstract: An expandable device for expanding and supporting body tissue comprises an inferior endplate having an outer surface configured to contact one body tissue surface and a superior endplate having an outer surface configured to contact an opposing body tissue surface. The inferior endplate and the superior endplate are movable relative to each other in a direction of expansion. The device includes an elevator captively supported between the inferior endplate and the superior endplate for independent movement along the direction of expansion. In the first direction the elevator is moved toward said superior endplate to lift the superior endplate and expand the device. In the second direction the elevator moves away from said superior endplate toward said inferior endplate to create a space for insertion of an insert into the expanded device.

Abstract: An expandable anterior lumbar interbody fusion device comprises a multiple piece construction that includes an outer shell, movable upper and lower endplates and a pair of laterally spaced supports therebetween. The endplates are initially nested within the outer shell and telescope through the outer shell when expanded by a secondary instrument. Each endplate includes fixation elements to anchor the expanded device in an intervertebral disc space. Bilateral internal pockets are formed within each of the endplates to fully contain the supports. Once the device is expanded, the supports are pushed into place by the instrument in a manner to maintain the expanded position. After the supports are in place, the expander instrument is removed, and the device remains anchored in the expanded state.

Abstract: A modular inserter assembly for use in inserting an interbody fusion cage into the disc space between opposing vertebrae comprises a depth stop and a modular inserter tip releasably attached thereto. The modular inserter assembly includes a cage attachment surface for releasable attachment to an interbody fusion cage, the depth stop including a movable stop axially movable relative to the inserter tip and being sized and configured to engage an exterior surface of one of the vertebrae to establish the depth to which the interbody fusion cage is to be inserted in the disc space. A plurality of modular inserter tips, each being configured for selective releasable attachment to differently sized interbody fusion cages are provided in a kit with the depth stop.

A stop, sized to engage an exterior surface of the vertebrae, is movable on the depth stop stem by rotation of an adjustment knob to a plurality of selectable distances between the proximal end of the trial device and the movable stop. An actuator releasably attached to the trial is operable to rotate the rasp. A plurality of modular trials, each having a trial device of different heights may be provided in a kit. Each scoring trial is selectively releasably attachable to a single depth stop.

Abstract: An accelerometer and a linear resonant actuator (LRA) are mechanically coupled, such as by being mounted to the same circuit board. The output of the accelerometer is evaluated in order to select a drive frequency for the LRA. For example, the drive frequency may be varied while measuring the magnitude of acceleration induced by the LRA. The output of the accelerometer may further be used to perform a fitness tracking function, such as counting steps or detecting an activity level.
