Abstract: Systems and methods for monitoring one or more anatomical elements are provided. An image depicting one or more anatomical elements and a plurality of annotations may be received. The image may comprise a plurality of image elements. Each annotation may correspond to one of the one or more anatomical elements and may be associated with one of the plurality of image elements. Movement information about movement of at least a portion of a particular anatomical element may be received. Image elements corresponding to the particular anatomical element may be identified to yield a set of image elements. The set of image elements may be adjusted based on the movement information to yield an updated image reflecting changes to affected anatomical elements.

Abstract: A system and method include transmitting a signal according to a set of frequencies. A frequency range associated with the set of frequencies is from about 300 Hz to about 30 MHz. The system and method include sensing an electromagnetic field based on transmitting the signal according to the set of frequencies and determining a distortion in association with sensing the electromagnetic field. The system and method include identifying frequencies at which the magnitude of the distortion is less than the threshold value. The system and method include transmitting the signal according to one or more of the identified frequencies and providing navigation information associated with an environment in response to transmitting the signal.

Abstract: The present invention provides immunoresponsive cells, including T cells, cytotoxic T cells, regulatory T cells, and Natural Killer (NK) cells, expressing an antigen recognizing receptor and an inhibitory chimeric antigen receptor (iCAR). Methods of using the immunoresponsive cell include those for the treatment of neoplasia and other pathologies where an increase in an antigen-specific immune response is desired.

Abstract: A system according to an embodiment of the present disclosure includes: a processor; and a memory storing data thereon that, when processed by the processor, enable the processor to: receive an image depicting an anatomical element; segment the image into a segmented image that includes a plurality of voxels; track a portion of a surgical instrument as the portion of the surgical instrument interacts with the anatomical element; identify, based on the tracking, an area from the segmented image representative of a section of the anatomical element that interacts with the portion of the surgical instrument; modify one or more voxels from the plurality of voxels that reside within the area identified from the segmented image as being representative of the section of the anatomical element that interacts with the portion of the surgical instrument; and render, to a display, the segmented image showing the modified one or more voxels.

Abstract: A spinal implant system includes a spinal implant template configured to provide three dimensional coordinates of a selected implant configuration. An implant bending device includes work surfaces engageable with a spinal implant to manipulate the spinal implant to the selected implant configuration and an implant contact sensor. Surgical instruments, spinal constructs, implants and methods are disclosed.

Abstract: In the field of agriculture and aerial firefighting, some example vent systems for aircraft fluid dispersion tanks include a vent-well recessed below the top of the tank. When a gate valve assembly below the tank opens to release fluid for dispersion along the aircraft's trailing flight path, the vent system prevents a detrimental vacuum from developing within the tank. In some examples, a recessed vent exploits the Coanda effect to direct air into the tank without obstructing the pilot's view. In some examples, a low profile scoop above the vent further promotes airflow with minimal visual obstruction. In addition or alternatively, some example vent systems include a lightweight cable connecting the gate valve assembly to a spring-loaded vent. The cable pulls the vent open in response to the gate opening to release fluid. When the gate closes, the cable becomes slack, which allows the spring to close the vent.

Abstract: A method according to one embodiment includes: determining a volume of a harvested autograft, the determining including: receiving an image depicting an anatomical element, the image segmented into a plurality of voxels with each voxel of the plurality of voxels labeled with either a first bone volume label representing a first volume type or a second bone volume label representing a second volume type; and summing a first set of voxel values labeled as having the first volume type and through which an operative portion of a navigated tool passes to determine the volume of the harvested autograft; and determining a total volume of a bone graft for a surgical task, the determining including: identifying a portion of a patient eligible for the bone graft; and summing a second set of voxel values associated with the portion of the patient to determine the total volume of the bone graft.

Abstract: A method according to at least one embodiment of the present disclosure includes: providing a first localizer relative to a patient anatomy; providing a second localizer in proximity to the first localizer; co-registering the first localizer and the second localizer; determining, based on tracking a pose of the first localizer, first localizer pose information; determining, based on a combination of the first localizer pose information and the co-registration of the first localizer with the second localizer, second localizer pose information; and outputting the second localizer pose information to at least one of a display device and a robotic controller.

Abstract: A guidance system for remotely guiding a work machine along a virtual path. The system uses a vision system to capture image data representative of areas surrounding the work machine. The image data is used to produce a spatial map. Analysis of image data allows the work machine's then-current position to be represented on the spatial map. A virtual path extending from the work machine's position is next added to the spatial map. The virtual path may be generated in response to external input provided at the display showing an image of the spatial map. Using continuously-updated image data, the work machine is driven toward the virtual path. During operation, the actual path of the work machine is compared to the virtual path. If any deviation between the paths is detected, the trajectory of the work machine is automatically adjusted.

Abstract: A system for tracking and steering a downhole tool using an augmented reality device. A tracker tracks the location of a downhole tool as it moves underground and transmits data to the device, while one or more sensors measure a position and orientation of the device. The device analyzes the data received from the tracker and the sensors and generates a virtual image of the downhole tool. The virtual image is displayed on the device at its detected location relative to the ground surface and relative to the position of the device. The position of the displayed virtual image is modified in response to updated information from the tracker or the sensors. Virtual images representing various parameters of the drilling operation are also displayed on the device in juxtaposition with the virtual image of the downhole tool.

Abstract: A dump gate system for a fluid hopper in a firefighting aircraft. A gate sealably engages a gate opening in the hopper at a closed position. The gate is hingedly connected about the gate opening, and a drive shaft is supported within the hopper. A crank arm is fixed to the drive shaft and is further coupled to the gate by a connecting link. The crank arm and the connecting link define an over-center geometry while the gate is at the closed position, such that weight of the fluid on the gate induces torque on the drive shaft in a gate-closing direction. A linear electric motor is selectively coupled to rotate the drive shaft in a gate-opening direction to thereby enable control of the fluid flow from the hopper according to an angular position of the drive shaft.
