Abstract: A material moving machine includes a chassis, a dual-sensor position sensor system including a master and a slave, and a controller. The master and the slave are each configured to generate independent position signals representing a machine position. The controller is programmed to determine whether the machine is tramming, determine whether the master and the slave are operational, determine a center of rotation (COR) of the chassis when the machine is not tramming, and determine heading(s) based on a pair selected from the COR, an operational master, and an operational slave. The controller is further programmed to determine a prioritized heading based on at least one of the operational master and the operational slave and based on an order of priority that ranks the heading(s), use the prioritized heading to generate the machine heading when the machine is not tramming, and operate the machine based on the machine heading.

Abstract: The invention provides a card having a combination of positive motivational, inspirational, and/or educational material printed thereon regarding a specific theme or message. The cards have material printed on at least one side thereof, and preferably on both sides. The material on the cards may also include drawings or photographs of persons, places or things. The material on the cards may further include biographical information, other factual data, and trivia. The material printed on each card pertains to a specific theme or message. The material on each card is written and/or organized in a manner not only to motivate, inspire, or educate, but also to influence or persuade the person viewing the information to act on the message, i.e., to adopt a personal behavior consistent with the message.
