Abstract: A method and a system for impact detection in a stationary vehicle are provided. The method includes putting a telematics device into a sleep mode, performing at least one micro wakeup, determining at least one value from at least one sensor during the micro wakeup. The method also includes storing the at least one value, returning to sleep mode, and waking up from the sleep mode. The method further includes sending the at least one value over a network interface to a telematics server.

Abstract: Devices and systems for determining an alternator condition in a motor vehicle are provided. The method includes performing a plurality of micro wakeups to capture voltage values during a cranking event, determining the maximum cranking voltage and its timestamp, detecting an ignition signal, determining the maximum device voltage and its timestamp, and determining a potential alternator undercharging condition if a duration between the maximum cranking voltage timestamp and the maximum device voltage timestamp is greater than an undercharging indicator duration threshold. Advantageously, an alternator may be repaired or replaced before it fails thus averting having the motor vehicles inoperable.

Abstract: This invention relates to the production of succinic acid and other chemicals derived from phosphoenolpyruvate (PEP) by fermentation with a microorganism in which the fermentation medium contains one or more sugars, and in which one or more of the sugars is imported into the cell by facilitated diffusion. As a specific example, succinic acid is produced from a glucose-containing renewable feedstock through fermentation using a biocatalyst. Examples of such a biocatalyst include microorganisms that have been enhanced in their ability to utilize glucose as a carbon and energy source. The biocatalysts of the present invention are derived from the genetic manipulation of parental strains that were originally constructed with the goal to produce one or more chemicals (for example succinic acid and/or a salt of succinic acid) at a commercial scale using feedstocks that include, for example, glucose, fructose, or sucrose.

Abstract: This invention relates to improvements in the fermentation process used in the production of organic acids from biological feedstock using bacterial catalysts. The improvements in the fermentation process involve providing a fermentation medium comprising an appropriate form of inorganic carbon, an appropriate amount of aeration and a biocatalyst with an enhanced ability to uptake and assimilate the inorganic carbon into the organic acids. This invention also provides, as a part of an integrated fermentation facility, a novel process for producing a solid source of inorganic carbon by sequestering carbon released from the fermentation in an alkali solution.

Abstract: Example systems, methods, and logic are provided herein for detecting a numerical identifier of an endpoint. In one example, a connectivity manager establishes a wireless communication session with a fixed endpoint using a wireless communication protocol. The connectivity manager module then generates a Phone Book Access Profile (PBAP) request to download a phone number associated with the fixed endpoint. The connectivity manager module receives, via the wireless communication session, a PBAP response comprising a phone number identifying the fixed endpoint and inputs the phone number identifying the fixed endpoint into a field used for initiating a call to the fixed endpoint.

Abstract: This invention relates to the production of chemicals by fermentation with a microorganism in which the fermentation medium contains the sugar sucrose. As a specific example, succinic acid is produced from a sucrose-containing renewable feedstock through fermentation using a biocatalyst. Examples of such a biocatalyst include microorganisms that have been enhanced in their ability to utilize sucrose as a carbon and energy source. The biocatalysts of the present invention are derived from the genetic manipulation of parental strains that were originally constructed with the goal to produce one or more chemicals (for example succinic acid and/or a salt of succinic acid) at a commercial scale using feedstocks other than sucrose. The genetic manipulations of the present invention involve the introduction of exogenous genes involved in the transport and metabolism of sucrose into the parental strains.
