Abstract: Methods and apparatuses for performing patient registration. 3D scan data from a 3D scanner, preoperative image data, first tracking data from a first tracking system, and second tracking data from a second tracking system are mapped to a common coordinate space. The 3D scan data and the first tracking data are mapped to each other using a transformation that is determined based on a calibration relating the 3D scan coordinate space and the tracking coordinate space. The 3D scan data and the preoperative image data are mapped to each other using a surface matching algorithm. The first tracking data and the second tracking data are mapped to each other based on tracking of the patient reference device.

Abstract: A device and method is provided for a trackable suction tool for surgical use. The suction tool provides multiple configurations for the tip and reference tree, while allowing tracking by a navigation system. The tip and reference tree are attached to the suction tool handle by a snap fit, a threaded ring with key and slot connections or semi-Allen key connections, providing specific rotational configurations of the tip, handle and reference tree with each other. The handle may include a rotatable outer sleeve with a tear-shaped orifice for suction regulation and an inner sleeve with a corresponding opening, allowing variable placement of the tear-shaped orifice relative to the longitudinal axis of the suction tool. The features of the device allow a suction tool with multiple configurations to be trackable with a navigation system.

Abstract: A handheld scanner is provided for use in registering a patient for a medical procedure with a medical navigation system. The handheld scanner has a housing having a main body portion having a first end and a second end and a handle portion having a first end and a second end with the second end attached to the second end of the main body portion with a bridge portion. The handheld scanner further has a circuit board contained in the housing, a processor connected to the circuit board, a light emitter contained in the main body portion and connected to the circuit board, a light detector contained in the main body portion and connected to the circuit board, and a button connected to the circuit board and located on the second end of the handle portion. The button is engageable by a thumb of a hand holding the handle portion.

Abstract: A strut-tower brace includes a pair of strut-tower attachments, and front and rear cross members extending between the attachments. The rear cross member has a flange configured to connected with a vehicle cowl. A lattice structure interconnects the cross members and has ribs that are each joined to another of the ribs at a node that is spaced between the front and rear cross members.

Abstract: The invention is directed to a process for extracting bitumen from poor oil sand ore involving mixing the poor oil sand ore with heated water to produce a slurry, and conditioning the slurry to yield a poor ore stream. In a separate train, good oil sand ore is mixed with heated water to produce a slurry, and conditioned to yield a good ore stream. Both the conditioned poor ore and good ore streams are combined in specified proportions to yield a blended slurry which is then fed to a primary separation vessel to produce primary bitumen froth.

Abstract: A process for extracting bitumen from oil sand, comprising: mixing oil sand with process water to produce an oil sand slurry containing bitumen, sand, water and entrained air; conditioning the oil sand slurry; optionally flooding the conditioned oil sand slurry with flood water to dilute the slurry, if required; introducing the slurry into a primary separation vessel wherein separate layers of primary bitumen froth, middlings and sand tailings are formed; removing a portion of the primary bitumen froth from the primary separation vessel and recycling the portion of primary bitumen froth to that step of the process upstream of the primary separation vessel to join and mix with the feed stream moving to the primary separation vessel; and thereafter retaining said feed stream in said primary separation vessel to produce primary bitumen froth.

Abstract: An aqueous aerated oil sand slurry is conditioned in a pipeline and then spun within an elongate vessel of circular cross-section, to cause bitumen droplets in the slurry to coalesce. This increases the probability that the droplets will become aerated by contact with air bubbles. The slurry is then subjected to separation of the sand and bitumen.
