A system for efficient delivery of radio frequency (RF) energy to cardiac tissue with an ablation catheter used in catheter ablation, with new concepts regarding the interaction between RF energy and biological tissue. In addition, new insights into methods for coagulum reduction during RF ablation will be presented, and a quantitative model for ascertaining the propensity for coagulum formation during RF ablation will be introduced. Effective practical techniques are presented for multichannel simultaneous RF energy delivery with real-time calculation of the Coagulum Index, which estimates the probability of coagulum formation. This information is used in a feedback and control algorithm which effectively reduces the probability of coagulum formation during ablation. For each ablation channel, electrical coupling delivers an RF electrical current through an ablation electrode of the ablation catheter and a temperature sensor is positioned relative to the ablation electrode for measuring the temperature of cardiac tissue in contact with the ablation electrode. A current sensor is provided within each channel circuitry for measuring the current delivered through said electrical coupling and an information processor and RF output controller coupled to said temperature sensor and said current sensor for estimating the likelihood of coagulum formation. When this functionality is propagated simultaneously through multiple ablation channels, the resulting linear or curvilinear lesion is deeper with less gaps. Hence, the clinical result is improved due to improved lesion integrity.

An oven for grilling food, is provided with: an outer shell (2), consisting of walls defining an internal volume, including a transparent portion (3); at least one door (4). The volume is subdivided into a zone (5) for heat production by heating elements and a cooking zone (6) including at least one grill (7) on which the food is placed. The at least one door (4) is associated with the at least one grill (7), which is slidingly supported inside the outer shell (2) and includes a bulkhead (8), opposite the door (4) with respect to the grill (7), arranged for closing the cooking zone (6) when the grill is fully extracted from the oven.

In a fuel cell stack ( 11 a), a larger number of fuel cells ( 18-21, 33-36 ) are interposed between successive cooler plates ( 13-15 ) without creating excessively high temperatures in those fuel cells ( 33-36 ) which are remote from the cooler plates, by virtue of increased air flow in air flow field channels ( 30 a) which are deeper in fuel cells ( 30-36 ) remote from the cooler plates, compared with the flow field channels ( 30, 30 b) which are in fuel cells ( 18-21 ) adjacent to the cooler plates. The thickness of air flow field plates ( 29 b) may be increased to accommodate the increased depth of the air flow channels ( 30 a). Fuel cells ( 18 a) adjacent the cooler plate may have air flow field channels ( 30 b) which are more shallow than normal whereby increased air utilization therein will be balanced by decreased air utilization in the cells ( 33-36, 33 a) having deeper air flow channels ( 30 a); in this case, the channels ( 30 a) may be normal or deeper than normal.

The invention relates to a thermal container which can be used to store drinks and food, characterised in that the walls thereof comprise three layers, namely: an intermediate layer (3) made from propylene, polyurethane foam or expanded polystyrene; an outer layer (2); and an inner layer (4), said outer and inner layers also comprising three panels in the form of an outer cardboard panel, an intermediate aluminium panel and an inner polyethylene panel. The container is intended primarily to retain the properties of wines under any circumstances and, more specifically, during transport from wine shops to the end user.

The invention provides a multifunctional teacup and belongs to the technical field of articles of everyday use. The multifunctional teacup solves the technical problems that according to existing teacups, carrying is not convenient and tea can not be made conveniently. The multifunctional teacup comprises an upper cup body, an intermediate lid and a vacuum cup body which has the heat preservation function, wherein the upper cup body, the intermediate lid and the vacuum cup body are combined in a stacked mode in sequence from top to bottom, the bottom of the upper cup body is fixed to the upper end of the intermediate lid, the lower end of the intermediate lid is detachably fixed to the upper end of the vacuum cup body, the upper end of the upper cup body is provided with a first cup rim, the upper end of the upper cup body is further provided with an upper cup lid which can seal the first cup rim, the upper end of the vacuum cup body is provided with a second cup rim, an inner plug which can seal the second cup rim is detachably connected to the upper end of the vacuum cup body, and the volume of the vacuum cup body is larger than the volume of the upper cup body. According to the multifunctional teacup, due to the fact that the vacuum cup body having the heat preservation function and the upper cup body which can be used for making tea and does not have the heat preservation function are arranged and are fixed into a whole organically through the intermediate lid, the portability of tea making tools is improved.
