Elastographic images provide visualization in two or three dimensions of RF ablation lesions to guide in the ablation process. Compression may be applied using the RF probe. A similar technique may be applied to in vivo imaging of soft tissue without ablation.

A non-volatile flash memory system counts the occurrences of an event, such as the number of times that individual blocks have been erased and rewritten, by updating a compressed count only once for the occurrence of a large number of such events. Complementary embodiments include updating the compressed count based upon a random number or upon the actual count matching a multiple of the fixed number. These techniques also have application to monitoring other types of recurring events in flash memory systems or in other types of electronic systems. In another aspect of the present invention, provisions are made to maintain an accurate experience count if the memory system experiences an improper shutdown, for example in case of power loss or removal of a memory card.

A gasket system for sealed interfaces utilizes a carrier ring having inner and outer compression stops to account for and control flange rotation effects in order to achieve a uniform and constant gasket seating stress across the sealing region. The inner compression stop provides a fixed fulcrum for flange rotation. The inner and outer compression stops have different heights, dependent upon the characteristic flange rotation, that allow the orientation of the sealing material to be angularly matched to the flange side profile and that allow the sealing material to be fully captured within the sealing region upon full compression, minimizing creep relaxation. A visual compression indicator on the circumference of the carrier ring permits assembly of the interface without the use of specialized or calibrated tools.

An intraocular lens is laterally compressed prior to insertion through an eye incision using an inserter adapted to minimize damage to the intraocular lens. The inserter includes a handpiece with a longitudinal bore, a cartridge holder at the distal end of the handpiece bore, and a discharge nozzle with a tapered bore on the distal side of the cartridge holder.

A method for generating a representation of a polyline formed by a sequence of points determines an overcomplete set of geometric primitives that redundantly fit overlapping sections of the polyline. The overcomplete fitting is performed such that the set includes one or more types of geometric primitives, each fitted to a section of the polyline formed by a subset of the sequence of points. The method determines a local cost of each geometric primitive based on a combination of a fitting error and an encoding cost of the geometric primitive, and determines a join cost of each successive pair of adjacent primitives. Next, the method determines a combination of the geometric primitives forming a connected path along a length of the polyline such that a sum of the local costs of the geometric primitives and the join costs of adjacent primitives in the combination is optimized.
