摘要： A method and apparatus for minimizing escapement positioning error by matching the move sequence of a print carrier to the mechanical system dynamic characteristics without the use of a feedback sensor are described. A plurality of constant velocity signals are provided for driving the print carrier to the next print position. The sequential velocity signals comprise an acceleration velocity signal and a deceleration velocity signal, the duration of which are dependent upon the damped natural frequency of the print system. For long escapement moves, a slew velocity command is provided between the acceleration and deceleration velocity commands so as to maintain the velocity of the print carrier at the amplitude it had attained at the conclusion of the acceleration velocity signal. The relative amplitudes of the acceleration, slew and deceleration velocity signals are a function of the damping ratio of the printer system.

摘要： A board-handling mechanism for more easily installing and removing boards from motherboards and/or other mountings within system enclosures does not require the removal of the enclosure. The mechanism provides leverage to positively seat and unseat circuit boards mounted into system connectors on the motherboard or other locations within system enclosures. A cable loop connector is provided within the enclosure opposite the opening for engaging the I/O connector on the forward edge of the daughterboard. The cable loop connector is biased to an upper position so that the daughterboard will first seat in the cable loop connector before being lowered and engaged to the motherboard connector.

摘要： A board-handling mechanism for more easily installing and removing boards from motherboards and/or other mountings within system enclosures such that it does not require the removal of the enclosure. The mechanism provides leverage to positively unseat circuit boards mounted into system connectors on the motherboard or other locations within system enclosures. A gripping mechanism is used for gripping one edge of the circuit board during the unseating process. The gripping mechanism is particularly adapted to provide additional force to unseat the circuit board. The gripping mechanism is adjustably mounted for accommodating circuit boards of various sizes.

摘要： A magnetic transducer is provided having a plurality of magnetic poles arranged annularly about an axis to form a stator coacting with a rotor which rotates about the same axis to induce changes in the magnetic forces between the poles. Each of the poles in the stator has a sense coil thereon for generating an electric output signal in response to the induced changes in flux. At least one pair of these magnetic poles have the same polarity and are positioned substantially 180.degree. apart. The sense coils on each of the poles in this pair are connected in series so that the resulting output electrical signal from these coils would be cumulative.
