Abstract: Medical procedure trays and related methods are provided to accommodate joining a first non-sterile medical device with a second sterile medical device and maintaining required sterilization of the second sterile medical device to perform an associated medical procedure. One example of such medical procedures includes biopsy of a bone and/or associated bone marrow using a non-sterile powered driver and a sterile biopsy needle or biopsy needle set. Each medical procedure tray may include a containment bag or sterile sleeve. A coupler assembly, one or more sharps protectors, a biopsy sample ejector and/or associated ejector funnel may also be included. Some medical procedure trays may allow engaging a non-sterile powered driver with one end of a coupler assembly and sealing the non-sterile powered driver in a sterile sleeve or containment bag without compromising sterility of other components in the medical procedure tray.

Abstract: An electrically operated displacement pump includes an electric motor having a stator and a rotor. The rotor is connected to the fluid displacement member to drive axial reciprocation of the fluid displacement member. A drive mechanism is disposed between and connected to each of the rotor and the fluid displacement member. The drive mechanism receives a rotational output from the rotor and provides a linear input to the fluid displacement member. A controller controls operation of the motor based on an operating state of the motor to control pumping by the displacement pump.

Abstract: A surgical instrument manipulator comprises a manipulator arm and an instrument mounting structure rotatably mounted to the manipulator arm. The instrument mounting structure comprises: an attachment interface configured to removably couple to a surgical instrument; and a passage within the instrument mounting structure. When the surgical instrument is coupled to the attachment interface, the surgical instrument is fixed to the instrument mounting structure. An elongate body of the surgical instrument extends through the passage when the surgical instrument is coupled to the attachment interface. The instrument mounting structure is rotatable relative to the manipulator arm, and when the surgical instrument is coupled to the attachment interface, rotation of the instrument mounting structure with respect to the manipulator arm causes rotation of the surgical instrument.

Abstract: A system for processing plastic waste may include a feed line, a feed fractionator, a hydrotreater, a catalytic reforming unit, a heavy oil cracker, and a steam cracker. A pyrolyzed plastics feed is separated into light, medium, and heavy hydrocarbon streams. The hydrotreater removes sulfur, and the catalytic reforming unit produces a circular aromatic-rich stream. The heavy oil cracker generates cracked streams. The steam cracker produces a circular olefin stream from a cracked stream. A system for processing plastic waste may include the feed line, the feed fractionator, the hydrotreater, a medium hydrocarbon fractionator, the catalytic reforming unit, a full-range reforming unit, the heavy oil cracker, and the steam cracker. The medium hydrocarbon fractionator produces two hydrocarbon streams. The full-range naphtha reforming unit produces a second circular aromatic-rich stream.

Abstract: Polymer composite photonic crystal materials are disclosed as coatings which have high reflection (>30%) in a specific range of the electromagnetic spectrum, such as ultraviolet (<400 nm), visible (Vis, 400 nm-700 nm), or near-infrared radiation range (NIR, 700-2000 nm), and relatively low reflection (<20% reflection) in a second, different range of the electromagnetic spectrum. Surprisingly, it was found that through a formulation and additives approach, the optical properties of polymer composite photonic crystal films can be selectively modified from a variety of different coating methods, including spray deposition.

Abstract: Group III nitride based light emitting diode (LED) structures include multiple quantum wells with barrier-well units that include III nitride interface layers. Each interface layer may have a thickness of no greater than about 30% of an adjacent well layer, and a comparatively low concentration of indium or aluminum. One or more interface layers may be present in a barrier-well unit. Multiple barrier-well units having different properties may be provided in a single active region.

Abstract: Various arrangements for performing intelligent cellular channel management are presented herein. A physical cellular communication channel may be established between a user equipment (UE) and a cellular network for sending a short message service (SMS) message in response to a cellular service request from the UE. One or more characteristics of the UE, the SMS message, or both may be analyzed. A duration of time for which the physical cellular communication channel is to be kept active may be based on the analyzed one or more characteristics. A channel maintenance instruction may be transmitted to keep the physical cellular communication channel active based on a cellular network messaging controller determining to adjust the duration of time for which the physical cellular communication channel is kept active.

Abstract: A head-mounted device may have optical modules that present images to a user's eyes. Each optical module may have a lens barrel with a display and a lens that presents an image from the display to a corresponding eye box. To accommodate users with different interpupillary distances, the optical modules may be slidably coupled to guide members such as guide rods. Actuators may slide the optical modules towards or away from each other along the guide rods. The guide rods may be formed from fiber-composite tubes with end caps that are fastened to a frame in the head-mounted device. The tubes may be partly or completely filled with cores to add strength. Low-friction coatings such as metal coatings may be formed on the fiber-composite tubes and the corresponding inner surfaces of the optical module structures that slidably engage the fiber-composite tubes.

Abstract: Apparatus and methods for optimizing bandwidth utilization and services in a data network infrastructure. In one embodiment, the data network is a managed Hybrid Fiber Coaxial (HFC) cable network, and the network infrastructure is configured to enable dynamic allocate of frequency bands to individual consumer premises device (e.g., DOCSIS-compliant cable modems). In one variant, the improved network infrastructure enables creation of virtual Service Groups (vSGs), and allocation of individual ones of the CM to such vSGs, to some degree irrespective of topological or “hardwired” location within the network. The allocations can be dynamic, and based on factors such as load balancing, evacuation of portions of the physical network topology (such as to support infrastructure upgrades or replacement), or for yet other reasons such as relating to subscriber tier or service level agreement (SLA).
