    摘要: Circuit for selectively enabling energization of printing electrodes in sequence in a print head to achieve a more nearly constant current flow in the electrodes to thereby produce recorded marks of more uniform size. The formation of the electrodes into gated small groups reduces the maximum allowable current and, hence, the electromagnetic radiation. During traversal of the print head along a print line, a lagging electrode group or groups are enabled before the leading groups regardless of travel direction to minimize recording impedance for energized electrodes.

    摘要: An optical connection means is provided for connecting an optical docking station to an information handling system and to one or more peripheral devices. The optical connection means comprises two components that are not mechanically attached. The two components are a laptop component that is housed within the information handling system and within the one or more peripheral devices, and a docking station component housed within the optical docking station. The components send and receive information optically (i.e., in the form of light) to each other.

    摘要: A robotic system includes two joints moving a common load-bearing member along a path for positioning a load. Each joint includes a linear electric motor and a feedback loop, the latter driving the motor accurately in response to a commanded position signal, and a true position signal provided by sensor apparatus disposed alongside a track of each linear motor. Cross-coupling circuitry connects with the sensor apparatus of each joint to produce signals representing differences in positional error and in speed of the joints. The signals are injected into the feedback loops of the joints to effect a shift of power between the joints to synchronize their travel. Window comparator circuitry is employed for introduction of variable gains to the feedback loops for values of positional error and velocity which are greater than reference values in a window. Simultaneous injection of phase lead angle to the electric motors is employed for transition to a high speed mode while retaining synchronized operation of the motors.
