Abstract: Disclosed are methods, apparatuses and software products for graphic processing using a visual display system and image analysis for sizing of surgical implants in the planning and execution of spinal surgery, such as spinal fusion surgery of the cervical spine. The graphic processing includes determining a trajectory line for one or more target spine levels captured and measured by one or more measuring system to generate a 3D motion dataset for use in a range of diagnostic and therapeutic applications.

Abstract: A motor vehicle includes a spoiler articulable between a stored position substantially flush with the body of the vehicle and a deployed position vertically spaced from the body of the vehicle. The aerodynamic member is interconnected to the body through first and second stanchions. The stanchions are oriented substantially vertical when the aerodynamic members in the deployed position and horizontal when the aerodynamic member is in the stored position. A drive arrangement moves the aerodynamic member between its stored position and its deployed position.

Abstract: An apparatus conceals a trailer hitch socket and provides a step. The apparatus includes a generally planar main body portion having a first side and second side. The apparatus further includes a mounting arrangement for pivotally interconnecting the generally planar main body portion for articulation between a first position and a second position. In the first position, the generally planar main body portion is vertically oriented and conceals the trailer hitch socket. In the second position, the trailer hitch socket is horizontally oriented and provides the step.

Abstract: A roof rack has a pair of laterally spaced apart rails. A pair of channels in a roof panel of an automotive vehicle are spaced apart the same distance as the rails. Operating mechanism is provided for moving the rails from a raised position of use projecting above the roof panel to a retracted position within the channels. The rails when retracted are substantially flush with the top surface of the roof panel.
