Abstract: A flow path duct system for a propulsion system of an aircraft includes a base defining a flow surface. The base has an internal surface and an external surface. A plurality of perforations are formed through the base between the internal surface and the external surface. A plurality of supports define a plurality of cavities. The plurality of supports extend outwardly from the external surface of the of the base. One or more of the plurality of cavities are in fluid communication with the one or more of the plurality of perforations. A backing surface is secured to the plurality of supports. The plurality of supports are disposed between the base and the backing surface. The one or more of the plurality of cavities are in fluid communication with an internal volume defined by the internal surface of the base through the one or more of the plurality of perforations. The base, the plurality of supports, and the backing surface can be integrally formed together as a monolithic, load-bearing structure.

Abstract: A power transfer system comprises a patient support apparatus and a separate power transfer device. The patient support apparatus comprises a support structure having a base and a patient support surface for a patient and wheels coupled to the support structure to facilitate movement of the patient support apparatus over a floor surface. One or more of the wheels includes a power receiver integrated therewith. The power transfer device is energizeable to interact with the wheel to facilitate power transfer between the power transfer device and the power receiver through the wheel.

Abstract: A kink-resistance catheter has a first pair of core wires residing in the catheter body on opposed side of a catheter lumen. The core wires have relatively stiff proximal ends but taper toward their distal ends. The tapered construction provides the core wires with a degree of distal flexibility that helps the catheter advance along a vasculature to a site of interest without kinking and with improved torsional rigidity. If desired, shaping ribbons are provided in the catheter body adjacent to the distal ends of the core wires. The shaping ribbons can be pre-bent before a surgical procedure to help the physician advance the catheter along the vasculature. Finally, the core wires provide the ability to push the catheter through the vasculature with out the need for the catheter to go over a guidewire already in-situ in the vasculature.

Abstract: A sensor assembly for an electric machine includes a position sensor mounted to the stator. The sensor assembly further includes a target configured to be inductively coupled to a transmit coil of the position sensor and a plurality of receive coils of the position sensor when the target passes the position sensor during a revolution of the rotor relative to the stator. The sensor assembly includes a circuit mounted to the rotor. The sensor assembly further includes a power generation element on the rotor. The power generation element generates electrical power needed for powering electronic components of the circuit based on an inductive coupling with the transmit coil when the power generation element passes the position sensor during the revolution of the rotor. The electronic components can include a sensor configured to obtain data that can be communicated to the position sensor mounted to the stator.

Abstract: An agent executed by a computer identifies a critical path of a transaction in a web application. The transaction includes a plurality of methods each representing an operation of the application and asynchronously executed by a server between a beginning of the transaction and an end of the transaction. The agent receives metrics for the transaction, which include identifiers of each executed method and specify relationships between the transaction methods. Based on the received metrics, the agent identifies a method completed at the end of the transaction. Based on the relationships between the methods, the agent determines one or more other methods preceding the identified method in the transaction and affecting a duration of the transaction. The determined methods and the method completed at the end of the transaction are identified as a critical path. Identifiers of the methods on the critical path are sent for display to a user.

Abstract: A patient support apparatus comprises a support structure comprising a base and a patient support surface to support a patient. An actuator system facilitates movement of the patient support surface relative to a floor surface. One or more sensors are responsive to changes in position of the patient support surface caused by the actuator system. A controller is operably coupled to the one or more sensors and the actuator system. The controller is configured to operate the actuator system to move the patient support surface and to monitor the movement of the patient support surface by sensing positions of the patient support surface over time. The controller is further configured to identify a frictional load event on the actuator system during movement in a present cycle and associate the frictional load event with a sensed position of the patient support surface in the present cycle.

Abstract: An augmented reality and extended reality surgical system comprising three 3D viewing options of: (i) an AR/XR headset or headsets, (ii) one or more autostereoscopic “3D glasses free” monitor(s); and (iii) one or more digital ocular stereoscopic 3D viewports which is mounted to a cobotic arm viewing option for ergonomically sound viewing. The system may comprise a wearable device, such as a head mounted display or glasses, that provides the user with virtual reality, augmented reality, and/or mixed reality for surgery visualization. This system is all digital and features both wired and wireless connections that have approximately the same latency of less than 20 milliseconds. This may allow the user to access 2D or 3D imaging, magnification, virtual visualization, six-degrees of freedom (6DoF) image management, and/or other images while still viewing real reality and thus maintaining a presence in the operating room.

Abstract: A guidewire having a fiber optic force sensor with a mirror having encoded reflectance is described. The guidewire has a distal housing supported by a core wire. A distal hypotube connected to the distal housing supports a spring intermediate hypotube proximal and distal portions. An atraumatic head is connected to the distal hypotube portion. An optical fiber having at least one fiber core extends through lumens in the core wire and housing to a distal end of the housing. A mirror supported by the atraumatic head faces proximally but is spaced distally from the fiber core at a distal face of the optical fiber. The mirror is provided with a pattern of reflectance that varies along a radius from a central area of reflectance. Light of a defined power shines from the fiber core to the mirror with a reflected percentage of the defined light power being reflected back to the fiber core.

Abstract: A medical system comprising a guidewire that is connectable to a catheter is described. The guidewire has a housing connected to the distal end of a core wire. A printed circuit board (PCB) electrically connected to a camera chip resides in the housing. An atraumatic lens is supported by the housing with the camera chip residing between the atraumatic lens and the housing so that light rays entering the atraumatic lens are refracted to a focal plane aligned along a distal face of the camera chip. A proximal connector powered by a controller is wired to a visual display. With the proximal end of the guidewire connected to the proximal connector, the controller provides electrical power to the camera chip via a power cable extending along the core wire to the PCB. The catheter has an axially-extending primary lumen and a plurality of optical fibers extending to respective light-emitting lenses. During a medical procedure, the guidewire is first inserted into the vasculature of a patient.
