Patent CA-2396759-A1 (CA)
Inventor: GUO ZIHONG
IPC: A61B18/14
Filed: 2001-01-16
Abstract: A combination catheter includes an ultrasound transducer and RF ablation electrode. The ultrasound transducer transmits ultrasound signals into and receives echo signals from a vessel. The echo signals are processed and used to produce an image of the tissue surrounding the catheter. A driveshaft rotates the ultrasound transducer to obtain a 360~ view of the vessel wall. At the distal end of the driveshaft is an electrode. An RF generator is electrically coupled to the driveshaft to deliver RF energy to the electrode at the distal end of the driveshaft to ablate occluding material in the vessel. The electrode may have a variety of tip shapes including concave, roughened, or expandable configurations, depending on the size of the vessel and composition of the occluding material to be ablated. Alternatively, the RF  ablation energy may be delivered to a guidewire that is used to route the ultrasound catheter through a patient's vasculature. Finally, a steerable catheter can be used to further position the ultrasound catheter and ablation electrode in the vessel.

Title: Versatile system for creating test images in a digital printing apparatus
Inventor: PHAM HUNG M
IPC: G06F3/12
Filed: 2002-08-21
Abstract: In a digital printing apparatus, such as a xerographic or ink-jet printer, test marks, such as halftone patches or fiducial marks for image registration, are generated on demand. Coordinates of a desired location of the test mark within an imageable area (such as on a print sheet or on a photoreceptor), as well as a selection of the desired type of test mark, are entered through a user interface. Also entered is data about conditions under which image-quality tests using the test marks are to be performed. Information about the test mark and test conditions is retained as a small number of scalar values. The system enables test methods for a machine to be changed easily, and a basic set of system software can be readily applied to different types of printing hardware.

Abstract: In a remote unit (50) of a slotted mode wireless communication system, the handoff performance is improved. Search parameters for a preferred base station, and a desired number of neighboring base stations, are passed to a search engine during a preparation period (46) of an active state (42) of the remote unit prior to its assign slot. While in the preparation period (46), the search engine performs (70) searches and the controller evaluates the results. If one of the neighboring base stations' pilot signal is sufficiently stronger than the preferred base station (74) then a handoff is performed, assigning (76) the neighboring base station as the preferred base station. The handoff is completed before the remote unit enters its assigned slot (48).
