    摘要： A robotic safety clutch that provides a wireless connection between the safety clutch and an robotic/automatic arm controller. The safety clutch includes a sensor for sensing a crash event and a radio frequency transmitter for transmitting a crash signal in response to the sensed crash event to a radio frequency receiver. The radio frequency receiver is connected to the robotic/automatic arm controller. Upon receiving the crash signal from the transmitter, the receiver sends a crash signal to the controller and in response to the crash signal, the controller shuts down all robotic/automatic functions.

    摘要： The tunnel-erase-type guard band "writing" along the tracks of a disk in a disk file is controlled by the same microcomputer which controls transducer repositioning in the seek mode. The micro-computer meters different delays for onset and cessation of erasing in relation to a signal (write gate) accompanying the data to be recorded; and these delays are longer for tracks having smaller diameters. The leading and trailing edges of the write gate signal trigger interrupts for the microcomputer, the interrupt channel is released only after the particular delay has been metered.

    摘要： A disk drive for one or more spinning disks has a voice coil motor, driving the transducer carriage and controlled by two feedback loops, respectively, for hold and seek modes and enabled by a microcomputer which is additionally inserted into the seek mode feedback loop. The microcomputer receives step pulses from a controller host as well as detent pulses through a path of that seek loop; the pulses serve as interrupts and the microcomputer selects digital speed signals on the basis of step and detect pulse counts. An a/d converter inserts that signal as command into the seek loop. The microcomputer performs basically a continuous loop type of program pursuant to which command (select) lines from the host are interrogated and the hold mode is maintained until, for example, one or more step pulses interrupt this program loop to command the drive to move the carriage to another track; the microcomputer then shifts the drive to the seek mode, which is maintained by the continuous loop until the carriage has arrived at the new position. Special subroutines cause the drive to center on a zero track when externally or internally commanded. A variety of diagnostic tests can be performed.
