摘要： Disclosed is a measurement system having multiple display orientations. The measurement system comprises a reader head having a reader element, and a display module. The reader element is configured for lateral movement with respect to a calibrated reference member for making a measurement relative to a reference position on the calibrated reference member. The display module is for displaying a measurement and includes coupling hardware for connecting the display module to the reader head so that the display module can be read horizontally independent of whether the reader head is oriented horizontally, vertically, or in some other direction.

摘要： Disclosed is a capacitive measurement system. The system comprises structure for generating a plurality of waveforms, a calibrated reference member for use with a reader head in making a measurement, and a reader element configured for lateral movement with respect to the calibrated reference member. The calibrated reference member comprises one element of a capacitor. The reader element comprises a plurality of reader regions comprising the other element of the capacitor. The reader element also includes structure for receiving two signals resulting from coupling of the two capacitor elements. The system functions to detect a phase shift level between the two signals and to determine magnitude of lateral movement in a particular direction from the magnitude of the phase shift.

摘要： Disclosed is a measurement system having reader element standoff. The system comprises a calibrated reference member for use with a reader head in making a measurement. The system also includes a reader head comprising a reader element configured to move laterally with respect to the calibrated reference member for making the measurement relative to a reference position on the calibrated reference member. Also, standoff structure is provided for establishing a variable standoff distance between the reader element and the calibrated reference member while substantially invariably maintaining a fixed lateral position of the reader element within the reader head.

摘要： A braking control circuit for an alternating current motor is disclosed as having a winding and adapted to be coupled to an energizing control circuit for connecting a source of AC voltage to and for disconnecting the source of AC voltage from the winding. The braking control circuit comprises a selectively controlled rectifier operative in a first conductive mode for applying rectified current to the winding to brake the motor and in a second non-conductive mode, and a switching circuit coupled to the rectifier and responsive to the disconnecting of the source of AC voltage from the winding for switching the rectifier between its first and second modes at a first switching rate to brake the motor rotation at a corresponding first braking rate, and thereafter for switching the rectifier between its first and second modes at a second switching rate different from the first switching rate to brake the motor at a corresponding second braking rate.
