General Motors produces vehicles in 37 countries under thirteen brands: Alpheon, Chevrolet, Buick, GMC, Cadillac, Holden, HSV, Opel, Vauxhall, Wuling, Baojun, Jie Fang, UzDaewoo. General Motors holds a 20% stake in IMM, and a 77% stake in GM Korea. It also has a number of joint-ventures, including Shanghai GM, SAIC-GM-Wuling and FAW-GM in China, GM-AvtoVAZ in Russia, Ghandhara Industries in Pakistan, GM Uzbekistan, General Motors India, General Motors Egypt, and Isuzu Truck South Africa. General Motors employs 212,000 people and does business in more than 120 countries. General Motors is divided into five business segments: GM North America , Opel Group, GM International Operations , GM South America , and GM Financial.General Motors led global vehicle sales for 77 consecutive years from 1931 through 2007, longer than any other automaker, and is currently among the world's largest automakers by vehicle unit sales.General Motors acts in most countries outside the U.S. via wholly owned subsidiaries, but operates in China through 10 joint ventures. GM's OnStar subsidiary provides vehicle safety, security and information services.In 2009, General Motors shed several brands, closing Saturn, Pontiac and Hummer, and emerged from a government-backed Chapter 11 reorganization. In 2010, the reorganized GM made an initial public offering that was one of the world's top 5 largest IPOs to date and returned to profitability later that year. Wikipedia.

A method for controlling a vehicle cabin climate is provided. The method includes the steps of receiving and aggregating data relating to one or more inputs, wherein at least some of the data is acquired at the vehicle and some of the data is acquired from sources located remotely from the vehicle. The method further includes using a climate control module to determine an optimal cabin climate based on the aggregated data, and controlling one or more climate features according to the optimal cabin climate.

A method, implemented at a server of an operations control center of a telematics service provider, for transmitting commands to a network access device, is described. The method involves creating one or more command data packets, each comprising a payload and control information, the control information identifying an AT command air interface. The method further involves transmitting, by the server, the command data packets to the network access device via the AT command air interface, wherein the AT command air interface is a first tunnel extending through a network of the vehicular telematics unit. In addition, a method, implemented at a baseband processor of a network access device of a vehicular telematics unit, for receiving commands from a server of an operations control center and a system for transmitting commands between a server of an operations control center and a network access device are also described.

Traditional shape memory polymers (SMPs) are those capable of memorizing a temporary shape and recovering to the permanent shape upon heating. Although such a basic concept has been known for half a century, recent progresses have challenged the conventional understanding of the polymer shape memory effect and significantly expanded the practical potential of SMPs. In this article, notable recent advances in the field of SMPs are highlighted. Particular emphasis is placed on how the new developments have changed the conventional view of SMPs, what they mean for practical applications, and where the future opportunities are. © 2011 Elsevier Ltd.

A system and method for securely providing a mobile device with a cryptographic key in a vehicle. The method includes generating a cryptographic key pair that includes a first and second cryptographic keys. One of the keys is used to create a scannable image which is then incorporated into a label that is displayed in the vehicle, either as a physical label mounted in the vehicle or via a display screen within the vehicle. The label containing the scannable image can then be read by a mobile device at the vehicle, thereby providing the one key to the mobile device for use in sending communications to the vehicle.
