Abstract: A polymer coating/ring is employed to aid in the sealing and connection of modular elements used in body flow lumens for the exclusion and bypass of diseased regions of the flow lumen, such as where aneurysm occurs adjacent to branching blood vessels.

Abstract: A system and method for displaying images of internal anatomy includes an image processing device configured to provide high resolution images of the surgical field from low resolution scans during the procedure. The image processing device digitally manipulates a previously-obtained high resolution baseline image to produce many representative images based on permutations of movement of the baseline image. During the procedure a representative image is selected having an acceptable degree of correlation to the new low resolution image. The selected representative image and the new image are merged to provide a higher resolution image of the surgical field. The image processing device is also configured to provide interactive movement of the displayed image based on movement of the imaging device, and to permit placement of annotations on the displayed image to facilitate communication between the radiology technician and the surgeon.

The vehicle further includes front drive axle and a rear drive axle configured to communicate power to ground engaging members. A traction battery is housed within the electric pushback vehicle and provides electric power to an electric motor to drive an output shaft. A transmission is connected to receive mechanical power from the electric motor through a torque converter.

Abstract: In general, the subject matter described in this disclosure can be embodied in a display panel. The display panel includes a first area of multiple pixels that has a first density of light emitting diodes (LEDs), and that has an equal representation of LEDs of a first color, a second color, and a third color. Each pixel in the first area has: (i) a first sub-pixel comprising an LED of the first color, (ii) a second sub-pixel comprising an LED of the second color, and (iii) a third sub-pixel comprising an LED of the third color. The display panel includes a second area of multiple pixels that borders the first area, that has a second density of LEDs that is lower than the first density, and that has an unequal representation of LEDS of the first color, the second color, and the third color.

Abstract: Distance-sensing techniques (between probes and a sample) utilize at least one of squeeze-film damping and temperature sensing for scanning probe microscopy. Squeeze-film damping may be used for “approach;” that is, z-position detection. It may also be used for “imaging;” that is, to obtain a topographic map of the surface of a sample.

Abstract: An augmented reality (AR) platform for the Internet of Things (IoT) is disclosed. The AR platform enables a user to associate AR objects with IoT devices. These associations may further enable a user to direct a control input to a particular IoT device and receive outputs such as sensor measurements or state information from the IoT device via interaction with an associated AR object. These AR objects may be perceived by the user via a client device, such as via an AR viewer or other human interface. The AR platform further enables users to create shareable objects that define an association among or between multiple AR objects and their IoT devices that can be shared with and modified by other users.

Abstract: The present disclosure seeks to provide a handpiece configuration for a surgical instrument such as an electrosurgical instrument to reduce the risk of a burn to the operator handling the handpiece. In particular, the present disclosure firstly provides an inner moulding in the handpiece for housing a motor and a suction path of the electrosurgical instrument. The inner moulding comprises a thermal conduction path between the motor and the suction path for the purpose of transferring heat generated from the motor to the exiting irrigation fluid in the suction path. The handpiece is further configured to comprise a thermally insulating outer casing surrounding the inner moulding. This configuration of the handpiece enables heat transfer from the motor to the irrigation fluid in the suction path while keeping the external surface of the handpiece cool.

Abstract: This application relates to methods and materials for providing a benefit to a seed or seedling of an agricultural plant (e.g., an agricultural grass plant or a Glycine plant), or the agricultural plant derived from the seed or seedling. For example, this application provides purified bacterial populations that include novel seed bacterial endophytes, and synthetic combinations of seeds and/or seedlings (e.g., cereal or soy seeds and/or cereal or soy seedlings) with heterologous seed-derived bacterial endophytes.

Abstract: An apparatus for use with a surgical instrument having a hollow shaft for transferring fluid and/or debris generated during use of the surgical instrument. The apparatus comprises: a drive unit comprising a driving part configured to generate a driving force for driving the surgical instrument, and a driven part driven by the driving part to transfer the driving force to the surgical instrument; and a channel arranged to receive the hollow shaft of the surgical instrument, the channel extending through the driven part of the drive unit.

The AR platform includes a feature set having a variety of AR-specific features that interact with and are accessible to the AR applications or AR layers that define a collection of AR content.

Abstract: A surgical device includes a handpiece having a socket, including a distal opening providing access to a passage having a longitudinal axis, and first and second electrical contacts located therein, wherein the contacts are displaced along the longitudinal axis so the first contact is more distal than the second. Also, a surgical instrument includes an elongate shaft having distal and proximal ends, wherein an end effector at the distal end is for treating tissue. Further, a connecting portion includes third and fourth electrical contacts, wherein the contacts are displaced along the shaft so the third contact is more distal than the fourth. The surgical instrument is coaxially coupled to the handpiece by the connecting portion received in the passage, so the first contact is aligned with the third and the second is aligned with the fourth to provide an electrical power signal from the handpiece to the surgical instrument.

Abstract: Systems and methods are described for establishing Proof of Location for a computing device (which may serve as Proof of Location for a user of the device). In some examples, establishing Proof of Location involves trackable features findable by the device at the location in question. In some examples, the computing device is configured to generate a point cloud of a trackable feature for comparison to a reference point cloud. Anti-spoofing methods are described for reducing the possibility of accidental or intentional false-positive Proof of Location results.
