Abstract: A low-cost, wide input range, DC-DC voltage-switching converter regulator device for supplying power to various components in an automotive application includes two pairs of serialized switch elements for controlling separate Boost and Buck Modes each through a respective one of said pairs.

Abstract: In a method for operating an electronic anti-theft system, data communication is effected between the control device and the key further to an access authorization request, whereby the control device unlocks the doors and deactivates an alarm system as a function of the data communication. The data communication for unlocking the doors and the data communication for disarming the alarm system are separate from each other. In this way, the mechanical unlocking of the doors can be initiated immediately after the data communication for unlocking the doors. The corresponding data communication for deactivating the alarm system is effected in parallel with this, whereby extensive cryptological data is exchanged between the control device and the key.

Abstract: In the device a controllable switch is built into the control device which enables the start authorization and by means of which the supply voltage with which this controllable switch is supplied can be switched off. To check a start authorization a diagnosis can be undertaken which is realized with known resistance elements in the voltage supply line between identification device holder and control device. This allows the voltage drops across the elements to be compared with the corresponding required values. Simple short circuiting of the starter or the ignition is thus no longer possible since this would be detected by the control device as a result of the changes in voltage drop. In addition a fault in the supply voltage or the feed lines can be definitively detected.

Abstract: A counter (2) alters its counter variable (C) on the basis of a clock signal which is generated by an oscillator (3). If the reset signal (CT1) intermittently transmitted by the processor (1) during normal operation is absent, the count variable (C) reaches a first limit value (Cgr1). The counter (2) then sends an interrupt signal (IR) to the processor (1). If the reset signal (CT) continues to be absent and the count variable (C) reaches a second limit value (Cgr2), the counter (2) transmits a hardware reset signal (HWR) to the processor (1). This signal or the result of this signal (HWR) is also used to reset the counter (2), i.e. the count variable (C) is set to a predetermined start value (CSTART). Thus, in the absence of the reset signal (CT1) from the processor (1), an interrupt (IR) and a hardware reset signal (HWR) are cyclically transmitted.

Abstract: Block polymers suitable for the preparation of data storage media are disclosed. The media produced of the inventive of the polymers has thickness in the range of a few millimeters. In contrast with currently available materials that feature high optical density the inventive polymers feature increased dilution of dyes (decrease in optical density) and decrease in the holographic diffraction efficiency.

Abstract: The present invention concerns a shelf-stable moist food foam product comprising a moist, foamed food base and at least one edible partially or fully denaturated protein which stabilizes the air bubbles in the food base and which contains more than 20% water.

Abstract: Methods are described herein for converting carbocationically terminated polymers to anionically terminated polymers. These methods comprise: (a) providing a carbocationically terminated polymeric moiety; (b) reacting the carbocationically terminated polymeric moiety with a heterocyclic compound of the formula where —X— is selected from —S—, —O—, —NH— and —NR—, and where R is an alkyl group or an aryl group, thereby providing an end-capped polymeric moiety; and (c) reacting the end-capped polymeric moiety with an organolithium compound to yield an anionically terminated polymeric moiety. Also described are block copolymers in which a first polymer block comprising cationically polymerized monomers is linked to a second polymer block comprising anionically polymerized monomers by a group, as well as a polymer in which a polymer block comprising cationically polymerized monomers is linked to a halogenated silane residue or a carbosilane residue by a group.

Abstract: The present invention relates to filled rubber mixes made from polyether/diolefin rubbers. The rubber mixes according to the present invention are suitable for the production of highly reinforced, abrasion-resistant moldings, in particular for the production of tires which exhibit low rolling resistance and elevated wet skid resistance.

Abstract: The present invention concerns a novel method for preparing polymers (preferably (meth)acrylate polymers and copolymers) having a narrow molecular weight distribution by metal-free anionic polymerization in the presence of a phosphonium salt of a nitrogen, oxygen and/or sulfur anion. The present invention also concerns block copolymer and methods of making the same using anionic polymerization in the presence of the phosphonium salt to prepare at least one block of the copolymer.
