| 20090154691 | Control circuit for controlling a DC supply voltage for a terminal - A control device for controlling a supply voltage which can be switched between a constant line current operation and a constant line voltage operation, wherein a line current, which consists of a direct current for supplying the terminal and of an alternating current for transmitting information, flows via a subscriber line of a terminal, comprising a sensing circuit for sensing an analogue input voltage dependent on the line current, a subtractor which, in the constant line current operation, subtracts an analogue feedback voltage dependent on an adjustable nominal direct-current value from the sensed input voltage for generating an analogue difference voltage, an analogue/digital converter for converting the generated analogue difference voltage into a digital difference voltage value, a digital low-pass filter for filtering a sequence of control error values out of the generated sequence of difference voltage values, a controller for generating a control value in dependence on the filtered-out sequence of control error values, and comprising a first digital/analogue converter which, in the constant line current operation, converts the control value in each case generated by the controller into the analogue direct voltage for supplying the terminal. | 06-18-2009 |
| 20110019315 | OVER-CURRENT PROTECTION FOR DC-TO-DC CONVERTERS - A DC-to-DC converter includes a switching control circuit adapted to provide a control signal having a duty cycle. A switching regulator is adapted to receive both a supply voltage having the first voltage level and the control signal. The switching regulator is further adapted to provide an output signal at the second voltage level as a function of both the supply voltage and the control signal. In addition, a current sensing circuit is adapted to provide at least one alarm signal based the duty cycle of the time-varying signal. Other systems and methods are also disclosed. | 01-27-2011 |

| 20090080811 | CHEMICAL, BIOLOGICAL, AND RADIOLOGICAL CONTAINMENT BAG - An isolation apparatus for transporting and storing objects or human remains. The apparatus is formed of a flexible, foldable, opaque, generally box-like enclosure fabricated of a fiber reinforced plastic film, and welded together to form a sealed, air-tight and/or liquid-tight enclosure. A gas and liquid sealing zipper is positioned along three of four sides of the enclosure, thereby allowing the apparatus to open in a clamshell or suitcase-like manner, for easy access to the interior of the enclosure. An NBC and/or a CBRN filter can be mounted to the apparatus to allow for release of pressure from within the enclosure. An interior liner made of chemical protective fabric can be placed within the enclosure for additional chemical containment. This apparatus eliminates or significantly reduces the size and number of cracks, crevices and/or other voids into which contaminated materials can enter, for example by positioning, sizing and/or structuring welds to extend completely to an edge of the isolation apparatus, and/or by welding materials together entirely around one or more peripheries. | 03-26-2009 |

| 20090030162 | Polyether-Functional Siloxanes, Polyether Siloxane-Containing Compositions, Methods For The Production Thereof And Use Thereof - The present invention provides a linear, cyclic or branched polyether-functional siloxane or a mixture of polyether-functional siloxanes of the general formula (I) R[—O | 01-29-2009 |
| 20110143147 | Agent for providing substrates based on cellulose and/or starch with water repellent and simultaneously antifungal, antibacterial insect-repellent and antialgal properties - The invention relates to an agent for providing substrates based on cellulose and/or starch with water-repellent and simultaneously antifungal, antibacterial, insect-repellent and antialgal properties, which contains water and, as active substance, at least one linear, cyclic, branched or crosslinked co-oligomer or mixtures of co-oligomers from the series consisting of the alkyl-/aminoalkyl-/alkoxy- or hydroxy-siloxanes, the use of such agents and a special treatment process using such agents. | 06-16-2011 |
