Title: Signal compression
Inventor: HAYES-GILL B R
IPC: A61B8/02
Filed: 1997-04-05
Abstract: A system 10 for obtaining a fetal Doppler audio signal from a patient 12, to allow medical staff to listen to the signal from a loud speaker 14, uses an ultrasound transducer 16 placed against the mother's abdomen. This creates a fetal Doppler audio signal in conventional manner. Apparatus 18 then provides a compressed signal which is transmitted by radio link 20 to a receiver 24, where the signal is decompressed to recreate the original Doppler audio signal at the loud speaker 14. Compression is provided by analysing the uncompressed signal in successive periods of time to count the number of zero-crossings occurring in each period, and also to monitor the amplitude of the uncompressed signal. A compressed signal is then created to represent the zero-crossing count data and the amplitude data. Compression allows a greater number of patients to be monitored simultaneously.

Title: 1XN and NXN fiber optics couplers
Inventor: PAN JING-JONG
IPC: G02B6/287
Filed: 1997-11-05
Abstract: The present invention provides fiber optic couplers (20) for use with at least three optic fibers (10). The optic fibers (10) arranged in linear-array, that is, the optical fibers (10) are coupled side by side, The fibers (10) along either end of the linear-array are coupled only to a single fiber (10A), while the remaining fibers are generally coupled between only two adjacent fibers (10). Generally, at least one of the fibers (10) has a propagation constant different than the other fibers (10). Such variations in the propagation constant are used to vary the coupling coefficients among the fibers (10) of the linear-array, thereby providing a repeatable mechanism, to vary coupled power ratios among the fibers (10) of coupler (20). Theoretical calculations and empirical experience have shown that varying the propagation constant of fibers (10) among a linear-array, generally by pre-pulling the fibers (10) by varying amounts, allows repeatable manufacturing of 1x3, 3x3, 1x4, 4x4, 1xN and even NxN fiber couplers having even coupled power ratios.
