The apparatus and method are designed to compute the optimal spatial and temporal characteristics for combating tumor growth within a body on the basis of cytological (as provided by biopsies, etc.) and anatomical data (as provided by CT, MRI, PET, etc.), as well as the electric properties of the different elements. On the basis of this computation, the apparatus applies the fields that have maximal effect on the tumor and minimal effect on all other tissues by adjusting both the field generator output characteristics and by optimal positioning of the insulated electrodes or isolects on the patient's body.

An intravascular delivery catheter includes a middle member or manipulator to ameliorate the effect of buckling of the graft cover during the tracking or positioning of the delivery device within a body flow lumen to deploy an exclusion device, such a stent graft. The delivery device/catheter includes a region or regions of lower resistance to bending than other portions of the delivery device, which are positioned, within the delivery device, to preferentially bend the delivery system at locations where buckling will have minimal effect upon the deployment of the exclusion device from the delivery system. The preferential bending is accomplished, by providing a middle member/manipulator that is a rod with laterally oriented slots, having different depth and spacing configurations, or by using a wire coil as a portion of the middle member where the variable stiffness is created either by providing a variable/multiple coil diameter or by using a wire having a variable diameter along its length while the wire coil diameter is relatively uniform.

A method, system, computer system and computer program product to maintain consistency between mirrored copies of data. A first data change map identifies regions that are about to be updated. If a system failure occurs during the update, the first data change map identifies regions that were being changed so that only those regions can be synchronized to restore consistency between the mirrored copies of data. A second data change map tracks changes made to data after a snapshot of the mirrored data is taken. This second data change map enables the mirrored copies of data to be synchronized without copying all data from one mirrored copy to another. The first and second data change maps are updated in parallel to reduce processing time and overhead. This parallel processing enables fast restoration and synchronization of mirrored copies of data, while having minimal effect on performance of applications using the data.

According to the present invention, a circuit and methods for enhancing the operation of SOI fabricated devices are disclosed. In a preferred embodiment of the present invention, a pulse discharge circuit is provided. Here, a circuit is designed to provide a pulse that will discharge the accumulated electrical charge on the body of the SOI devices in the memory subarray just prior to the first access cycle. As explained above, once the accumulated charge has been dissipated, the speed penalty for successive accesses to the memory subarray is eliminated or greatly reduced. With a proper control signal, timing and sizing, this can be a very effective method to solve the problem associated with the SOI loading effect. Alternatively, instead of connecting the bodies of all SOI devices in a memory circuit to ground, the bodies of the N-channel FET pull-down devices of the local word line drivers can be selectively connected to a reference ground. This would enable the circuit to retain most of the speed advantages associated with SOI devices while overcoming the loading problem described above. With this preferred embodiment of the present invention, the major delay caused by the bipolar loading effect is minimized while the speed advantage due to providing a lower, variable Vt effect is preserved. The overall body resistance of the individual devices has a minimal effect on the device body potential.

A method, system, and computer-readable medium to quickly synchronize copies of data that have diverged over time. The present invention can be used in synchronizing replicated copies of data that have become unsynchronized due to the restoration of primary data from a backup copy of the primary data. The solution enables copies of data to be synchronized without copying all of the data from one copy to another. The solution uses minimal resources to maintain data consistency and has minimal effect on performance of applications using the data and on network usage. The method includes determining that a change occurred to data in a region of a primary volume without including the region in a set of regions designated for replication to a secondary volume. The region is added to the set of regions designated for replication to the secondary volume and replicated.

A variety of loudspeaker arrangements may have any of multiple adjacent magnetic circuits, single magnetic circuits, an improved loudspeaker voice coil assembly, multiple voice coil windings (124-127, 315-317), and commutated current. The radial direction of flux may alternate at adjacent poles and may have a controller that commands the current through each of the windings. The position of the moving components may be measured or inferred by the controller (213). An encoding track (318a) applied to the surface of the assembly may allow the assembly to function as part of a position transducer to permit appropriate action based on position. Calculated or sensed actual position may be used to determine the relative current in each of the windings and the controller may have compensation such as a motion control algorithm, thermal monitoring, and management of the driver. The voice coil assembly (305c) may have foil conductors applied to a substrate to connect and interconnect a single or multiple voice coil windings with minimal effect on the magnetic gap (303b) width.

An electric machine having a stator surrounding a rotor with an air gap therebetween. The stator has slots in its inner margin for accommodating stator coil windings. Stator teeth defined by the slots have irregular shapes to modify a variable flux flow pattern in the air gap to reduce harmonic torque components with minimal effect on an average value of rotor torque.

An endoscopic instrument has a control member, a portion of the member having an outer surface with a non-circular cross-sectional shape. The non-circular cross-sectional shape may be provided to the control member by providing peripheral projections or fins along the length of the portion or by providing the periphery of the portion with a polygonal shape. Where fins are used, the fins are preferably quite small and only have a minimal effect on the fluid flow cross-sectional area between the interior of the endoscope instrument shaft and the central control member. The resulting instrument has significantly reduced backlash in end effector assembly manipulation, while maintaining adequate fluid flow in the endoscope shaft. According to a second embodiment of the invention, a portion of the interior of the shaft of the endoscopic instrument has an interior surface having a non-circular cross-sectional shape by the inclusion of a plurality of radially spaced and inwardly directed ribs or by being polygonally shaped. The resulting endoscopic instrument likewise reduces the backlash experienced in operating the distal end effector assembly.

The switching or swapping is implemented with no or minimal effect on the active session or awareness of the remote party. The device switch may be performed in relation to any active session, including VoIP, video conferencing, or other media sessions.

According to the present invention, fat and caloric content of processed cheeses can be reduced by the replacement of a portion fat content normally found in processed cheeses with an equal amount of emulsified liquid shortening composition comprising dietary fiber gel, water and lipid. The result is that fat and caloric content of processed cheeses can be manipulated with minimal effect on taste and texture. Furthermore, these emulsified mixtures, or “emulsified liquid shortening compositions comprising dietary fiber gel, water and lipid”, can further comprise functional foods such as high omega three and omega six oils and pure omega three and omega six fatty acids, medium chain triglyceride, beta carotene, calcium estearate, vitamin E, bioflavonoids, fagopyritrol, polyphenolic antioxidants of vegetable origin, lycopene, luteine and soluble fiber, for example Beta-Glucan derived from yeast, and other soluble fibers derived from grain, flax seed, and other vegetable and fruit fiber sources, and any combination thereof. Hence, in addition to reducing fat and caloric content of processed cheeses, further health benefits can be achieved by replacing a portion of fat with emulsified liquid shortening compositions comprising dietary fiber gel, water and lipid.

The fuel efficiency of an internal combustion reciprocating piston engine may be increased through selective secondary expansion of exhaust gas in the engine cylinders in order to recover exhaust gas energy which is otherwise wasted by cylinder blow-down at the end of the power stroke. Exhaust valve cam switching, intake valve deactivation, multiple exhaust valves, a specialized exhaust manifold arrangement and an exhaust gas diverter valve can be configured to enable a reciprocating engine to selectively operate in efficient eight stroke cycle compound mode when moderate engine power is demanded, then revert to conventional four stroke cycle non-compound mode operation when high engine power is demanded, without stopping the engine. For a road vehicle application, the benefit is substantially reduced highway cruising fuel consumption, while incurring minimal impact on engine weight, minimal impact on engine manufacturing cost, and no adverse impact on vehicle acceleration performance, hill climbing performance or trailer towing performance.

This invention involves encapsulating an RFID device in an encapsulating material by known encapsulating processes to form a domed, encapsulated RFID tag. The encapsulating material may be translucent or opaque, flexible or hard, and has minimal effect on transmission or reception of radio frequency (RF) signals. The invention further involves a stand-off bracket, composed of one or more materials that have minimal effect on transmission or reception of RF signals, for mounting an RFID device on or near materials that impede RF transmission and reception. The encapsulated RFID tag and stand-off bracket, separately, may have an adhesive or other attachment means on one of their surfaces so that they may be adhered or otherwise attached to another surface. In one application, an encapsulated RFID tag in the 860-928 MHz range is mounted on a stand-off bracket and may be used for tracking items to which it is attached.
