Abstract: The disclosure describes a system and method for the reprogramming of the electronic control units (ECU) devices simultaneously in one or more motor vehicles using a radio broadcast system to transmit a digital radio signal to a receiving electronic control units (ECU) device present in the motor vehicles.

Abstract: The invention relates to a system and method for the reprogramming of ECU devices in automotive vehicles, via digital radio, which allows new software files to be transmitted when synchronizing a radio station, automatically and safely downloading the new updates without having to take the vehicle directly to a dealership, characterized by comprising means for encrypting audio files with software files, data files with vehicle information files; means for mixing the files to be transmitted simultaneously from a radio broadcast station in digital format; means for receiving the files by digital radio receiver that are sent to receiving ECUs in the vehicles; memory means for storing said files; means for demodulating the files; means for decrypting the files that are retransmitted within the bus of the ECU device through the internal network of the vehicle, so that all ECUs receive the message simultaneously and, after authenticating the information, auto-reprogram with the software file received in an applicat

Abstract: A method and system for normalizing various simulcasting nodes within a distributed antenna system (DAS) simulcast sector uses the simulcast sector's known fiber delays, the distance between the nodes, and its corresponding RF delays. The methodology includes adding calculated delays to the known fiber delays to normalize each node's delay. Each normalized node delay value is equal to the value of the fiber delay of the furthest node plus the respective RF delay distance from that node.

Abstract: A method and system for providing E911 services for a distributed antenna system uses a lookup table including round trip delay (RTD) ranges for a number of nodes of the distributed antenna system to determine a serving node for an E911 call. The method and system disclosed herein, may calculate such lookup table based on the values of the fiber delays and air delays for each node on the distributed antenna system. After determining the serving node for an E911 call, the system may use triangulation method to determine the exact location of the wireless unit generating the E911 call.

Abstract: Coating dispenser apparatus and methods which utilize a snuff back device for removing a small amount of coating material from the discharge passage of the dispenser upon shut-off thereof at the end of a coating run. A control is provided which discharges the material removed from the discharge passage back into the discharge passage upon a predetermined delay after the start of the next coating run. The disclosed methods contemplate the discharge of coating material back into the discharge passage in the middle of the next coating pattern, or depending on the application, during any segment of the next coating pattern after a defined leading edge of the pattern is created, during which segment the coating material discharged back into the discharge pattern smoothly blends into the coating pattern as it is applied to a substrate. The apparatus and methods are especially useful for applying conformal coating patterns onto circuit boards.

Abstract: Pressure-sensitive "hot melt" adhesive compositions based on styrene-butadiene radial block copolymers, styrene-isoprene linear and/or radial block copolymers and plasticizing oils, are characterized in that they maintain low tack values (peeling, quick Stick) although having a good balance of properties normally required.
