Abstract: A digital electronic hybrid circuit for a telephone line circuit is described wherein the two-to-four wire conversion function is provided with an improved synthesized automatic impedance match between the telephone subscriber line and the digital central office. More particularly, an impedance at the input to the line circuit is simulated without the use of discrete components and which closely matches the subscriber line impedance. The circuit digitally separates the full duplex signals on a two-wire transmission path to a pair of digital signals.

Abstract: An apparatus and method for monitoring the operation of a hollow drive shaft is disclosed. An instrument is inserted within the shaft. A first end of the instrument includes an elastomeric retainer having a relaxed outer diameter which is slightly smaller than the inner diameter of the shaft. The retainer is compressed to expand in into frictional engagement with the inner surface of the drive shaft to retain the instrument therein. A generator is mounted within the instrument for rotation therewith. The generator includes a relatively rotatable output shaft having a pendulum attached thereto. When the drive shaft is rotated, the instrument and the generator rotate therewith, but the output shaft and the pendulum do not. Consequently, an electrical output signal is generated which is representative of the rotational speed of the shaft. Several sensors are provided to generate electrical signals representative of the torsional stress within the shaft during use and the ambient temperature therein. The output signals are fed to a control circuit in the instrument. The control circuit includes a power supply sub-circuit for supplying electrical power to the various components thereof. The power supply sub-circuit includes batteries for maintaining the supply of electrical power when the drive shaft is not rotated during use and means for re-charging the batteries when the drive shaft is rotated. A power regulator sub-circuit regulates the electrical power supplied to most of the components of the control circuit. A wake-up sub-circuit generates a signal when the shaft is rotated. The control circuit is maintained in an active operating condition when the shaft is rotated and is automatically placed in a stand-by operating condition after a predetermined length of non-rotation.

Abstract: The present invention concerns a coherent light source based on frequency conversion of the radiation from two lasers (20, 21) by frequency mixing in optical waveguides (10; 90), which are provided in a substrate (1). The wavelengths for the two lasers (20, 21) should be such, that the phase matching condition for the optically nonlinear frequency conversion is fulfilled in the waveguide structure (10; 90). The frequency conversion is accomplished in the form of frequency mixing, frequency doubling or down conversion in frequency by parametric oscillation so that in total three or four new wavelengths can be generated. By using integrated optics technique the output radiation can be controlled in various ways, for example be switched to different output waveguides, varied in intensity or colour balance.
