Slew (spacecraft)
Slew and slewing are terms which can refer to a spacecraft's orientation or movement in reference to a plane or fixed position such as Earth, the Sun, another celestial body or other point in space. During space flight, a craft's attitude must be controlled for reasons dependent upon the craft's mission. Keeping a spacecraft slewed properly is vital toward ensuring that its high-gain antenna remains oriented toward Earth for sending and receiving data and commands. Additionally with many craft, keeping their solar arrays angled toward the Sun optimizes their power absorption and reduces the craft's reliance on internal power systems. Thermal heating and cooling of a craft and its subsystems can also be controlled by the craft's orientation. Cameras or other sensing equipment that are fixed into position upon the craft need to be aimed by slewing the craft. A spacecraft can either be spin stabilized or 3-axis stabilized to maintain proper orientation. For spin-stabilized spacecraf ...

Slewing
Slewing is the rotation of an object around an axis, usually the z axis. An example is a radar scanning 360 degrees by slewing around the z axis. This is also common terminology in astronomy. The process of rotating a telescope to observe a different region of the sky is referred to as slewing. The term slewing is also found in motion control applications. Often the slew axis is combined with another axis to form a motion profile. In crane terminology, slewing is the angular movement of a crane boom or crane jib in a horizontal plane. The term is also used in the computer game Microsoft Flight Simulator ''Microsoft Flight Simulator'' is a series of amateur flight simulator programs for Microsoft Windows operating systems, and earlier for MS-DOS and Classic Mac OS.

Eigenvector Slew
In aerospace engineering, especially those areas dealing with spacecraft, the eigenvector slew is a method to calculate a steering correction (called a slew) by rotating the spacecraft around one fixed axis, or a gimbal. This corresponds in general to the fastest and most efficient way to reach the desired target orientation as there is only one acceleration phase and one braking phase for the angular rate. If this fixed axis is not a principal axis a time varying torque must be applied to force the spacecraft to rotate as desired, though. Also the gyroscopic effect of momentum wheels must be compensated for. That such a rotation exists corresponds precisely to a main result of the mathematical theory of rotation operators, the (only real) eigenvector of the rotation operator corresponding to the desired re-orientation is this axis. Given the current orientation of the craft, and the desired orientation of the craft in cartesian coordinates, the required axis of rotation ...

Jenny Slew
Jenny Slew (1719 – after 1765) was one of the first black Americans to sue for her freedom, and the first person to succeed through trial by jury.Sara Kakazu, "Slew, Jenny, 1719–?)," in ''African American National Biography'online/ref> Biography Early life Jenny Slew was born around 1719 to a free white woman, Betty Slew, and a man of African descent, likely a slave. Slew lived a life as a free woman in Ipswich, Massachusetts up until 1762. Marriages Slew was married several times, all to enslaved men. Kidnapping In January 1762, when Slew was forty-three, she was kidnapped from her home in Ipswich and forced into servitude by John Whipple Jr. ''Slew vs. Whipple'' In 1765, three years after her kidnapping, Slew brought a suit to court. She demanded her freedom and 25 pounds in damages, charging Whipple with violating her liberty. Most colonies denied slaves the right to sue in court, but Massachusetts allowed slaves to bring forward civil suits, even though they wo ...

William Hester
William Ewing Hester Jr. (May 7, 1912 – February 8, 1993), also known as Slew Hester, was an American tennis player and official. He was president of the United States Tennis Association (USTA) from 1977 to 1978, and the first USTA president from the Deep South. In spite of protests against the apartheid regime from African nations and civil rights activists, Hester let South Africa compete in two tournaments against the United States, first in Newport Beach, California, in April 1977 and next at Vanderbilt University in Nashville, Tennessee, in March 1978. He moved the USTA out of the West Side Tennis Club into the USTA National Tennis Center. He was inducted into the International Tennis Hall of Fame in 1981. Early life William Hester was born on May 7, 1912 in Hazlehurst, Mississippi. He graduated from Millsaps College in 1933. During World War II, Hester participated in the Red Ball Express. He was awarded a Bronze Star Medal for his service. Career Hester began his caree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Slew Footing
A tripping (or obstruction tripping) penalty in ice hockey and ringette is called by the referee when a player trips an opposing player with their hockey stick or ringette stick, or uses their skate against the other players skate ("slew footing"), causing them to lose balance or fall and obstruct them from making their desired play. This article deals chiefly with ice hockey. A tripping call usually results in a two-minute minor penalty on the player that caused the infraction. However, if the player is called for slew footing, he receives a match penalty. If the player was tripped on a breakaway (with no opponents to pass other than the goaltender), a tripping call may instead result in a penalty shot for the tripped player. See also *Penalty (ice hockey) A penalty in ice hockey is a punishment for an infringement of the rules. Most penalties are enforced by sending the offending player to a penalty box for a set number of minutes. During the penalty the player may not part ...

Slew Rate
In electronics, slew rate is defined as the change of voltage or current, or any other electrical quantity, per unit of time. Expressed in SI units, the unit of measurement is volts/second or amperes/second, but is usually expressed in terms of microseconds (μs) or nanoseconds (ns). Electronic circuits may specify minimum or maximum limits on the slew rates for their inputs or outputs, with these limits only valid under some set of given conditions (e.g. output loading). When given for the output of a circuit, such as an amplifier, the slew rate specification guarantees that the speed of the output signal transition will be at least the given minimum, or at most the given maximum. When applied to the input of a circuit, it instead indicates that the external driving circuitry needs to meet those limits in order to guarantee the correct operation of the receiving device. If these limits are violated, some error might occur and correct operation is no longer guaranteed. For exampl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
