Abstract: A mobile work machine is provided with a prime mover supported by a chassis, a first hydraulic pump driven by the prime mover, a work attachment powered by the prime mover, and a traction system. The traction system can include a ground engagement assembly for propelling the chassis. The mobile work machine can include an electronic controller configured to execute a traction speed control algorithm in which the position of the power reduction device is operated by the electronic controller to reduce available fluid pressure to a traction control device without receiving an actual traction speed feedback signal at the electronic controller. Alternatively, or in addition, a commanded position of the power reduction control device can be calculated by the electronic controller as a function of a requested prime mover operating speed demand reduced by a calculated adjustment factor.

Abstract: Systems and methods are disclosed for use in electronic guidance systems for surgical navigation. A sensor is provided with an optical sensor, to provide optical information, and a measuring sensor, to provide measurements for determining a direction of gravity. The sensor communicates optical information and measurements to an inter-operative computing unit. In an embodiment, the inter-operative computing unit receives first optical information for a registration device and a patient anatomy and a measurement to determine a direction of gravity to perform a registration step. The inter-operative computing unit receives second optical information for the patient anatomy and an object and determines and presents measurements relative to the anatomy. The measurements relative to the anatomy are determined from the second optical information, and in relation to the registration of the anatomy of the patient.

Abstract: Apparatus for variable width turn-up procedures on a paper processing machine. The apparatus may include a turn-up tape dispenser fixedly attached to a proximal end of a transverse track and movable with the transverse track along the first linear bearing. A movable turn-up tape exit point may be mounted to a second linear bearing. The second linear bearing may be independent of the transverse track or attached to the transverse track. The apparatus may include a brake operable to secure the transverse track in a position relative to the surface of the first spool. Furthermore, the apparatus may include a movable track curve that allows a placement of the track curve to be moved.

Abstract: Presented are methods and systems for determining, monitoring, and displaying the relative positioning of two rigid bodies such as during a surgery. In particular, the present disclosure relates to methods and systems for positioning a prosthesis relative to a bone during a surgery as well as to systems and methods for verifying resulting relative positioning of adjacent bones.

Abstract: A bone cap (100) for preventing leakage of medullary canal components in a residual limb (102) that can lead to pathologies such as heterotopic ossification reducing heterotopic ossification and a method for using the same are provided. The bone cap (100) includes a proximal base (114) and an insertion extension portion (116) extending from the proximal base (114). The insertion extension portion (116) has an outer surface and a distal end (112b) opposite the proximal base (114). The insertion extension portion (116) is configured to be inserted into a resected portion of a bone (104) of a patient. The bone cap (100) also has at least one bone engaging feature (120) disposed on the outer surface of the insertion extension portion (116) adjacent to the distal end (112b) of the insertion extension portion (116). A porous coating (122) is disposed on the outer surface of the insertion extension portion (116) adjacent to the proximal base (114).

Abstract: Methods and a kit for a navigated procedure, such as a navigated surgical procedure relate to an optical sensor system such as a sterile optical sensor system. The methods relate to using components of the optical sensor system and a processing unit, for example, performing a navigated procedure using an optical sensor as draped and using the processing unit coupled to the optical sensor. Performing the navigated procedure comprises receiving instructions for the navigated procedure from the processing unit, and using the optical sensor comprises interacting with a button on the optical sensor through the drape to provide input to the processing unit. A kit comprises optical sensor system components and instructions for performing a method.

Abstract: Apparatus and methods for improved turn-up procedures on a paper making machine that include a flexible portion of a turn-up tape track and movement of a track curve portion to avoid interference with threading a paper web to a spool. A transverse turn-up tape track may be extended across a first spool to a track curve and the track curve may be set at a lower position that does not interfere with a paper web during threading, and subsequently repositioned to a position from which a turn-up position may be performed. The paper web threading leader may continue to be wound around the first spool until a full width of the paper web has been spooled onto the first spool. The transverse turn-up tape track may be maintained essentially stationary relative to the first spool.

In one example, a system to make sterile a non-sterile optical sensor for use in navigational guidance during surgery includes a sterile drape having an optically transparent window to drape the optical sensor in a sterile barrier and a sensor alignment mechanism. The alignment mechanism secures the sensor through the drape in alignment with the window without breaching the sterile barrier and facilitates adjustment of the orientation of the optical sensor. The optical sensor may be aligned to view a surgical site when the alignment mechanism, assembled with the sterile drape and optical sensor, is attached to a bone. The alignment mechanism may be a lockable ball joint and facilitate orientation of the sensor in at least two degrees of freedom. A quick connect mechanism may couple the alignment mechanism to the bone.

Abstract: Systems and methods are described herein to generate a 3D surface scan of a surface profile of a patient's anatomy. The 3D surface scan may be generated by reflections of structured light off the surface profile of the anatomy. The 3D surface scan may be used during intra-operative surgical navigation by a localization system. Optionally, a pre-operative medical image may also be registered to the localization system or used to enhance the 3D surface scan.

Abstract: Systems, methods and devices are described herein for performing a navigated surgical procedure involving a patient's anatomy in sterile and non-sterile surgical environments. A camera may be used to determine a registration of the camera coordinate-frame to the patient anatomy or optionally a tracker in relation to the patient anatomy. A drape may be applied to permit use in a sterile surgical environment. The camera may be moved from its original position to enable access to patient anatomy while maintaining a registration of the camera coordinate-frame with the patient anatomy. Alternatively, the camera may be used in a hand-held or head-mounted manner. A visualization of the patient anatomy may be displayed on a computing unit, with visualization reference planes defined by the pose of an instrument or the camera. The visualization may be presented on a display of a computing unit or as part of a head mounted augmented reality system.

Abstract: A hood for a hooded garment may include apertures in the hood to improve a sealing connection between headphone earpieces and the outer portion of the user's ears while using headphones while also maintaining the hood's ability to retain body heat when not using headphones. While using the hood with headphones, the apertures may improve the sealing connection between the headphone earpieces and the user's ears and, thus, improve the function of the headphones (e.g., sound translation or sound deadening). While using the hood without headphones, a portion of mesh fabric sewn into the hood over the apertures allows the hood to retain the user's body heat and thereby mitigate heat loss through the hood caused by the apertures.
