Abstract: Methods and systems for providing feedback during a medical procedure. The 3D position and orientation of a tracked tool are determined, relative to a site of the medical procedure, based on tracking information received from a tracking system. The 3D position and orientation are mapped to a common coordinate space, to determine the 3D position and orientation relative to a field-of-view (FOV) of an optical camera that is capturing an optical image of the site. Navigational information associated with the 3D position and orientation is determined. A virtual representation of the navigational information overlaid on the FOV and displayed. The displayed virtual representation is updated when the 3D position and orientation of the tracked tool changes or when the FOV changes, in accordance with the change.

Abstract: A sweeper attachment for a refuse collection vehicle that utilizes either a conveyor system or a vacuum system to transport debris from a road surface to a collection body of the refuse collection vehicle. The sweeper attachment allows for the same vehicle to be used for both refuse collection and sweeping roadway surfaces.

Abstract: A collection mechanism for a side loading refuse collection vehicle that can move both horizontally and vertically to service multiple compartments designed for specific types of refuse or recyclables. A grabber assembly can move horizontally on a rail in either a lowered position or in a raised dumping position. The grabber assembly can move vertically on a mast. Preferably a sprocket wheel and a track are utilized to move the grabber assembly vertically from a street position to a dumping position.

Abstract: Methods and devices to track patient anatomy during a surgical operation. A patient reference device is attached to an anatomical feature of a patient and it includes an attachment base and an optically-trackable array detectable by an optical navigation system and having a longitudinally-extending arm to space apart the fixed geometric pattern from the anatomical feature. The arm includes a connector to be detachably secured to the attachment base. An inertial measurement unit within the attachment base enables determining, based on comparing a threshold level to a motion signal, that the attachment base has changed position, wherein the motion signal represents the change in position and its magnitude. Based on determining that the attachment base has changed position an alarm signal is generated an and an output device in the attachment base outputs an alarm in response to the alarm signal.

Abstract: A cam follower roller assembly has a shaft insertable into a roller. The shaft has a zerk in communication with the channel wherein lubricant can be added to the assembly. The design of the assembly in one embodiment is such that a larger shoulder to shaft radius stabilizes the shaft and limits the shaft from rocking or elongating within a mounting hole. When utilized in the application of a loading mechanism and carriage assembly for trash collection vehicles, one embodiment of the cam follower roller assembly provides greater life and easier serviceability.

Abstract: An attachment for a side loading refuse vehicles wherein the attachment can secure several different types of refuse containers. The attachment is operated without electronics and hydraulics, thus making retrofitting already in-use refuse vehicles easy and inexpensive.

Abstract: Methods and systems of performing intraoperative image registration during a medical procedure are described. A depth-encoded marker is provided to an object of interest. The marker is imageable by at least two imaging systems. The marker has asymmetry in at least a depth dimension. First and second sets of image data are obtained. Tracking data is obtained. The first image coordinate space, the second image coordinate space and the tracking coordinate space are independent from each other. Transformation mapping is performed to register the first and second sets of image data and the tracking data to each other. The first and second sets of image data are mapped to each other based on the depth-encoded marker. The first or second set of image data and the tracking data are mapped to each other based the same or different marker.

Abstract: A refuse collection assembly for a refuse collection vehicle mounts to a intermediate container on the refuse collection vehicle. The refuse receptacle collection assembly can grasp a refuse receptacle at curbside, at street side, or forward of the intermediate container in any location over a one hundred eighty degree arc. The collection assembly grasps the receptacle and locates it above the intermediate container and tilts it sufficiently to empty the contents of the receptacle in the intermediate container. The collection assembly then returns the receptacle upright to its previous location or to any location to the right, left or forward of the refuse collection assembly. The refuse receptacle collection assembly includes a rail extending along a wall of the intermediate container, a carriage selectively movable along the rail, and a receptacle engaging assembly supported by the carriage for grasping the refuse receptacle.

Abstract: An improved front loading or side loading refuse collection body includes an ejector panel which is moveable from a position immediately adjacent the front end wall of the storage compartment of the refuse collection body to a second position at the open rear end of the storage compartment. A compaction blade in a compaction chamber adjacent the front end of the storage compartment is independently driven by a second hydraulic ram. The ejector panel has an opening which is in registry with the opening in the front wall of the storage compartment through which refuse is pushed by the compaction blade. A tray member may be fixed to a side of the ejector panel to catch refuse which falls back through the opening in the ejector panel when it is moved away from the front end of the storage compartment. A multiple compartment body may include two compaction chambers each adjacent one of two storage compartments.
