| 20110017433 | HEAT EXCHANGER FOR A HEATING DEVICE - A heat exchanger for a heating device, especially a fuel value heating device, made up of at least two vertically aligned members, and, in each case, one cover at the end face, which form a combustion chamber, and laterally border at least one heating gas flue, that leads from the combustion chamber in the upper region downwards to an exhaust collector in the lower region, having heat exchanger surfaces which, on the heating gas side, are provided with elements that increase the size of surfaces, especially in the form of ribs, optionally having at least one middle member between the two bordering outer members, and having a plurality of channels guiding the heating medium flowing through in parallel and/or in series in the members and/or the covers. The present system provides a compact heat exchanger for a heating device, and which is light and is especially suitable for the fuel value operation. In the present system, the members and the covers are connected to one another at the end face to form a block that is leak-proof to the heating gas, whose channels guiding the heating medium correspond to one another. The heat exchanger surfaces, acted upon by heating gas, of two adjacent members, over their length have a greater distance from one another in the middle, and thus form a wider heating gas flue than in the edge regions, the ribs each having a greater height in the middle and overlapping one another over a greater surface than in the edge regions. | 01-27-2011 |

| 20090262327 | MASK TRANSPORT SYSTEM CONFIGURED TO TRANSPORT A MASK INTO AND OUT OF A LITHOGRAPHIC APPARATUS - A mask transport system is configured to transport a mask into and out of a lithographic apparatus. The mask transport system includes a first container configured to shield a top side and a bottom side of the mask. At least a portion of the container is at least partially translucent for radiation having a predetermined wavelength used to detect contamination on the top side or the bottom side of the mask when the mask is shielded by the first container. The mask transport system also includes a second container configured to enclose the first container. The second container includes a first part defining a first opening and an openable cover that covers the first opening. The cover is configured to open and release the first container within the lithographic apparatus or at an interface with the lithographic apparatus. | 10-22-2009 |

| 20100213870 | DIMMER JITTER CORRECTION - A controller and a method for controlling lamp drivers such as e.g. LED drivers for lamps having a fast response behavior such as e.g. LED lamps are proposed. They enable to substantially reduce or prevent a visible luminance flicker at such lamps when dimming the lamps with a conventional dimmer such as e.g. a phase cut dimmer. This can be achieved by switching off the lamp driver prematurely in such a way that a time jitter of a dimmer switching does not influence an on-time of the lamp driver. No bulky or expensive filters or capacitors are needed. Thus, a space-switch saving and/or inexpensive construction is enabled. | 08-26-2010 |
| 20110043129 | DIM RANGE ENHANCEMENT FOR LED DRIVER CONECTED TO PHASE-CUT DIMMER - The present invention relates to a driving circuit ( | 02-24-2011 |
| 20110149444 | SURGE PROTECTION CIRCUIT - A surge protection circuit is disclosed for an electrical Load which may be for instance an LED load which is directly connected to a supply such as mains supply, and comprises a plurality of switches which are distributed across a plurality of semiconductor die. A surge detector detects the start of a spike in the supply, which results from, for example the commencement or interruption of a nearby inductive load, and opens all the switches. By distributing the switches across multiple die the peak voltage across each is reduced relative to using a single die; thereby each die can stay within the absolute maximum voltage capacity. Each die may have its own surge detector; alternatively, a single surge detector may be used which communicates with the switches on each of the die. In an extension the bridge rectifier may be integrated into the circuit distributed across the die. In this embodiment additional inter-die clamping diodes are required to prevent unsafe floating of the edge connections of each die. | 06-23-2011 |
