The Ford Expedition is a full-size SUV built by the Ford Motor Company. Introduced in 1996 for the 1997 model year as a replacement to the Ford Bronco, it was previously slotted between the smaller Ford Explorer and the larger Ford Excursion, but as of the 2005 model year, it is Ford's largest and last truck-based, off-road and tow-capable SUV. The Expedition is based heavily on the Ford F-150 pickup and continues to share various components (transmissions, electronics, chassis control systems, towing features, etc.) with the full-size half-ton pickup truck. Ford currently offers the standard regular-sized model and the longer EL/Max model, succeeding the Excursion which was discontinued in 2005.
The Expedition is the third Ford vehicle to use the "Expedition" name, as it was originally used on a 1992 concept vehicle, the F-150 Eddie Bauer Expedition. The name was subsequently and briefly used for one of the Explorer Sport (two door)'s trim levels during the 1995 model year, before finding a home on the full-size SUV for the 1997 model year. All Expeditions were originally built in Wayne, Michigan. In 2009, Ford shifted its current third generation (2007–present) model production to Louisville, Kentucky when Ford converted the Wayne assembly plant to begin further production of the Focus. A refreshed third generation will arrive to dealers in 2014 for the 2015 model year.
Radio frequency (RF) engineering is a subset of electrical engineering that deals with devices that are designed to operate in the Radio Frequency spectrum. These devices operate within the range of about 3 kHz up to 300 GHz.
A keyless entry system is an electronic lock that controls access to a building or vehicle without using a traditional mechanical key. The term keyless entry system originally meant a lock controlled by a keypad located at or near the driver's door, that required pressing a predetermined (or self-programmed) numeric code for entry. These systems, having evolved into a hidden touch-activated keypad, are still available on certain Ford or Lincoln models.
The term remote keyless system (RKS), also called keyless entry or remote central locking, refers to a lock that uses an electronic remote control as a key which is activated by a handheld device or automatically by proximity.
A unique key or primary key is a key that uniquely defines the characteristics of each row. The primary key has to consist of characteristics that cannot collectively be duplicated by any other row.
In an entity relationship diagram of a data model, one or more unique keys may be declared for each data entity. Each unique key is composed from one or more data attributes of that data entity. The set of unique keys declared for a data entity is often referred to as the candidate keys for that data entity. From the set of candidate keys, a single unique key is selected and declared the primary key for that data entity. In an entity relationship diagram, each entity relationship uses a unique key, most often the primary key, of one data entity and copies the unique key data attributes to another data entity to which it relates. This inheritance of the unique key data attributes is referred to as a foreign key and is used to provide data access paths between data entities. Once the data model is instantiated into a database, each data entity usually becomes a database table, unique keys become unique indexes associated with their assigned database tables, and entity relationships become foreign key constraints. In integrated data models, commonality relationships do not become foreign key constraints since commonality relationships are a peer-to-peer type of relationship.
A transponder chip disarms a vehicle immobiliser when the car key is used to start the engine. The majority of keys to cars built after 1995 contain transponder chips.
Finance is the practice]citation needed[ of funds management, or the allocation of assets and liabilities over time under conditions of certainty and uncertainty. A key point in finance is the time value of money, which states that a unit of currency today is worth more than the same unit of currency tomorrow. Finance aims to price assets based on their risk level, and expected rate of return. Finance can be broken into three different sub categories: public finance, corporate finance and personal finance.
