The Goodrich Corporation formerly the B.F. Goodrich Company, was an American aerospace manufacturing company based in Charlotte, North Carolina. Founded in Akron, Ohio in 1870 as Goodrich, Tew & Co. by Dr. Benjamin Franklin Goodrich. The company name was changed to the "B.F. Goodrich Company" in 1880, to BFGoodrich in the 1980s, and to "Goodrich Corporation" in 2001.In 1869 Benjamin Franklin Goodrich purchased the Hudson River Rubber Company, a small business in Hastings-on-Hudson, New York. The following year Goodrich accepted an offer of $13,600 from the citizens of Akron, Ohio, to relocate his business there. Goodrich ranked 67th among United States corporations in the value of World War II military production contracts.The company grew to be one of the largest tire and rubber manufacturers in the world, helped in part by the 1986 merger with Uniroyal . This product line was sold to Michelin in 1988, and the company merged with Rohr , Coltec Industries, and TRW Aeronautical Systems in 2002. The sale of the specialty chemicals division and subsequent change to the current name completed the transformation. In 2006, company sales were $5.8 billion, of which 18%, 16% and 12% of total revenues were accounted for by the U.S. government, Airbus and Boeing, respectively.In 1936 the company entered the Mexican market in a joint venture with Euzkadi . The Troy, Ohio plant was purchased in 1946 from Waco. Since then, Goodrich has manufactured wheels and brakes for a variety of aircraft. Among these are commercial, military, regional, and business programs. This successful operation lies at the core of Goodrich's business. Competitors include the aerostructures divisions of companies such as Honeywell, Messier-Bugatti, Aircraft Braking Systems, and SNECMA. The Hood Rubber Company was sold before the Great Depression as a division of the B.F. Goodrich Company.Though BFGoodrich is a popular brand name of tires, the Goodrich Corporation exited the tire business in 1988. The tire business and use of the name was sold to Michelin. Before the sale to Michelin, Goodrich ran television and print ads showing an empty expanse of blue sky, to distinguish themselves from the similar-sounding Goodyear tire company. The tag line was, "See that blimp up in the sky? We're the other guys!" The company was also sometimes confused with Mr. Goodwrench as the two last names were very close and especially when B.F. Goodrich tires were featured on many General Motors cars and trucks. Wikipedia.

Systems and methods for detecting wheel speed are provided. An electric circuit (100) for detecting a speed of a wheel (304) may comprise: a transducer (102) in electronic communication with an operational amplifier (OP-AMP) (110), the transducer (102) configured to output a variable signal (122) in response to an angular velocity of a rotatable member of a wheel assembly (300) to one input of the operational amplifier; a constant voltage source (104) in electronic communication with the other input of the OP-AMP (110); and a sensor (128) in electronic communication with an output terminal (136) of the OP-AMP (110) configured to monitor an output signal (126) of the OP-AMP (110) representing a comparison of the transducer signal with the constant voltage, the output signal (126) being periodical and consisting of pulses having a particular period (152); and a controller (320) configured to receive the output signal (126) and to calculate the speed of the wheel (304) according to a pre-determined ratio between the wheel speed and the period (152). In various embodiments, the circuit (100) may allow for slow wheel speed detection.

A method of making a hoist cable capable of continuous resistance monitoring includes applying an electrically-insulating material to at least one strand of a wire rope such that a length of the strand is electrically insulated and an end of the strand is electrically conductive. The end of the at least one strand is joined to other strands of the wire rope such that at least two strands are electrically connected at a free end of the wire rope. A method of inspecting the hoist cable includes transmitting a first electrical signal through a first strand from a hoist drum to a free end of the wire rope and receiving the first electrical signal through a second strand at the hoist drum, the first and second strands being electrically connected at the free end. Using the first electrical signal, the resistance of the wire rope is calculated.

A system, apparatus and method provide emergency differential braking for effecting braked steering of an aircraft. A brake input device is provided that not only allows for emergency and parking brake functions, but also enables differential braking. The brake input device (e.g., a parking and/or emergency brake lever, pedal, handle, etc.) can be used in a brake system including a brake system control unit (BSCU), one or more electro-mechanical actuator controllers (EMACs) and a brake assembly including one or more electrical actuators. Each EMAC is electrically coupled to one or more of the actuators so as to provide electrical power for driving the actuators. Each EMAC is also communicatively coupled to the BSCU so as to receive braking data therefrom. In an emergency, the input device sends braking signals directly to the brake actuators.
