Title: Ringtrip detection circuit for use on telephone systems
Inventor: SESSOM JERRY
IPC: H04M3/02
Filed: 1992-05-19
Abstract: ABSTRACT            A RINGTRIP DETECTION CIRCUIT FOR USE ON TELEPHONE SYSTEMS     The present invention implements a ringtrip circuit that compares the positive and negative energies of the ringing current.  The term energy, as used here, implies total duration that the current is positive or negative. The current during ringing is sampled by a cycle detec-tor.  The positive and negative durations are measured by an up/down counter and compared to a known value by a comparator.  Any DC shift in the current will begin in-creasing the difference between the positive cycle dura-tion of ringing and the negative cycle.  If the differ-ence exceeds some number set forth in the logic, then a ring trip will occur.  The sampling of the ringing cur-rent is performed with opto devices to maintain isolation from the digital portion of the circuit.

Abstract: In order to reduce the complexity of an adaptive digital filter used to cancel delayed network echoes, a delay circuit is arranged in series therewith end arranged to compensate for the delay inherent with a speech codec. In the case of a variable delay circuit, the degree by which the echo is delayed is detected in the adaptive digital filter and used to modify the delay time. A gain control arrangement can be provided and used to reduce the gain of the received signal when the near-end party is talking and the adaptive capacity of the adaptive digital filter is exceeded.

Inventor: SUGANUMA HIROSHI
IPC: G02B6/28
Filed: 1992-06-16
Abstract: The first process for producing an optical fiber coupler includes a first step wherein at least one of the optical fibers to be used is stripped of the coating, a second step in which the bare portion of that optical fiber is heated for a predetermined time to diffuse the dopants, a third step wherein the other optical fibers which have not been heat-treated are stripped of their coating, a fourth step in which the bare portions of all the optical fibers are heated as they are brought into intimate contact, thereby forming a unitary portion, and a fifth step wherein the unitary portion is drawn via heating to form the coupling portion of an optical fiber coupler.  The second process for producing an optical fiber coupler includes stripping the coating from at least one optical fiber, fixing the fiber so as to impart an axial stress thereto and then heating the bare portion of the stripped optical fiber thereby thinning the diameter of the heated portion, and then proceeding in the same manner as described with respect to the third through fifth steps of the first embodiment of the present invention.  The processes according to the present invention enable a wide-band optical fiber coupler to be easily produced without using optical fibers of different structures but using optical fibers of identical structures.

Patent CA-2075370-A1 (CA)
Inventor: LESKO JOHN J
IPC: G01N33/44
Filed: 1991-02-05
Abstract: Disclosed is a method and apparatus of indentation testing of variable types of specimens which includes mounting an indenter member (3) into a thermally expandable member (2), mounting the specimen (5) to be tested on a pedestal (4), loading the specimen with the indenter member by thermally expanding the thermally expandable member and measuring applied force to and displacement of the specimen so as to determine the hardness or other material properties of the specimen. The indenter member is thermally insulated from the thermally expandable member prior to thermally expanding the thermally expandable member. The thermal expansion driven indentation system in the present invention allows for controlled application of precise and continuous reproducible loads to produce stress-strain plots. Continuous indentation testing with this system has yielded results which correlate well to Rockwell fixed load hardness tests on standard test blocks. Further, efforts in drawing relationships with tensile results have shown support for the use of continuous indentation testing for the generation of local material properties.
