Abstract: The present invention comprises a working implement, such as a snowplow, that can be attached to a vehicle. The assembly contains its own power source, and is controlled remotely, such as wirelessly. This combination allows the operator of the vehicle to lift and lower the jack on the unattached working implement as required without exiting the vehicle. In one embodiment, the system further includes wireless remote control operation of the headlights and blinkers, thereby eliminating another physical connection that typically exists between the vehicle and the working implement. The wireless remote control operation of the jack enables proper positioning of the lift frame relative to the vehicle chassis for easy mounting and dismounting thereto. In certain embodiments, the engagement of the assembly's connection mechanism with the vehicle, such as with a receiver on the vehicle, creates an electrical connection that enables communication between the assembly and controls for the assembly.

Abstract: A stenting system includes a stent delivery catheter (2) having a catheter shaft with a step balloon (3) mounted thereon. The step balloon has a proximal portion (31) and a distal portion (32), wherein the proximal portion is inflatable to a larger expanded diameter than the distal portion. A two-part stent has a proximal part (11) that is mounted on the proximal portion of the step balloon and a distal part (12) that is mounted on the distal portion of the step balloon and a non-link zone (13) between the proximal part and the distal part of the two-part stent. The proximal part and the distal part of the two-part stent are each configured with stent struts that extend like interdigitating fingers into the non-link zone to provide improved strut coverage in the carina region of the bifurcated vessel. The non-link zone effectively eliminates any difficulties in alignment of the two parts relative to one another during placement of the two-part stent in a bifurcated vessel.
Patent CA-2631167-A1 (CA)
Inventor: GARLOW MARK E
IPC: F04B49/00
Filed: 2006-11-29
Abstract: A method and apparatus are provided for estimating and/or precluding stick-slip, or other oscillatory or resonant behavior, through use of a virtual transducer, which precludes the need for having sensors located adjacent to a driven element of the system, or adjacent contact surfaces at which the stick-slip relative motion may occur. Parameters measurable at a drive mechanism are utilized for controlling a system in a manner which precludes stick-slip, or other oscillatory or resonant behavior, of the driven element. Relative motion between contacting surfaces in the driven element, prone to stick-slip behavior, is controlled such that, after sufficient force is applied by the drive element to overcome static friction forces between the contacting surfaces and break them free from one another, relative motion between the surfaces is maintained at a high enough relative speed that the surfaces are precluded from statically contacting one another, so that stick-slip behavior is precluded.
