Title: Trouser-fly piece serging apparatus
Inventor: FUKUMOTO YASUHIRO
IPC: D05B35/00
Filed: 1991-09-06
Granted: 1997-12-23
Abstract: A  trouser-fly piece serging apparatus includes a guide unit disposed upstream of a serging station and composed of a first elongate guide member extending at an angle relative to the path of movement of a trouser-fly piece being advanced by a serging unit, and a second elongate guide member extending parallel to the path of movement of the trouser-fly piece.  The trouser-fly piece is guided by the first guide member into the serging station so that a trimming cutter disposed immediately upstream of the serging unit assumes a position to conform to a curvature of the leading end of a substantially arcuate trimming line passing across a corner of the leading end of the trouser-fly piece.  Synchronous operation of the serging unit and the trimming cutter causes the trouser-fly piece to turn in one direction during which an arcuate corner which is trimmed by the trimming cutter and subsequently serged by the serging unit is automatically produced on the leading end of the trouser-fly piece.  Then, the trouser-fly piece is guided by the second guide member, and as the trouser-fly piece is further advanced, a curved longitudinal edge of the trouser-fly piece including the trimmed arcuate corner is completely serged with an overedge or serge stitching.

Title: Telephone handsfree algorithm
Inventor: REESOR GORDON
IPC: H04B3/23
Filed: 1991-09-27
Granted: 2000-05-23
Abstract: A handsfree telephone circuit has separate transmit and receive audio paths for connection to a microphone and speaker respectively. The circuit comprises a controllable attenuator in each of said transmit and receive paths, an attenuator control responsive to control signals to set the attenuation level of said attenuators, and a separate monitoring circuit connected to each of said transmit and receive paths for sensing audio signals therein. Each monitoring circuit comprises a filter for band limiting the audio signals, a peak level detector receiving said band limited signals, and a speech detector for distinguishing speech from background noise. A switching comparator compares the outputs of the peak level detectors in the two monitoring circuits and produces directional control signals for said attenuator control means to determine which audio path has control. The circuit is prone to causing a "hollow" effect in the speech due to bandlimiting filtering in the audio paths.

Patent CA-2056886-C (CA)
Inventor: PASTOR JOSE
IPC: H04L9/06
Filed: 1991-12-04
Granted: 1996-06-04
Abstract: A method for the secure communication of messages.  A first party is provided with a set of numbers that have the property that when encrypted using an RSA encryption key the resulting set of encrypted numbers is of an order substantially smaller than that of the original set.  If the encryption key and the original set of numbers are of the order of 200 decimal digits then the resulting set of encrypted numbers may be of the order of 15-30 decimal digits. To communicate a message the first party selects a number from the original set and applies a hashing function to the selected number to obtain a 64 binary bit DES key.  The selected number is then encrypted with the RSA key and a message is encrypted with the DES key obtained.  The encrypted message and the encrypted selected number are combined and the combined message is sent to a second party who has the corresponding RSA decryption key and knows the hashing function.  The second party then decrypts the number, applies the hashing function to obtain the DES key and decrypts the message.  Thus the parties may communicate with substantially the security of RSA while significantly reducing the minimum message length which may be securely encrypted.

An image stabilization system (40) is also provided which includes a detector (58) for monitoring an interference pattern created by the signal beam and the reference beam. Circuitry (60) is included for providing control signals in response to the detector (58) outputs. A phase shifter (44) induces a phase shift in the reference beam. A phase shifter positioning mechanism (46) adjusts the phase shifter (44) in response to the control signals so that the image is stabilized on the film (26) despite the movement thereof.

Abstract: In an ATM cell assembling and disassembling method for a communications network having first and second communications nodes, HDLC data is transferred from a first terminal to the first communications node via a first transmission line, the HDLC data conforming to an HDLC format.  It is started to assemble, in the first communications node, at least one cell from the HDLC data when data which is contained in the HDLC data and equal to one cell has been received.  Then the above at least one cell is transferred from the first communications node to the second communications node. Disassembly is started, in the second communications node, of the above at least one cell to thereby generate original HDLC data when a fluctuation compensation time has elapsed after a first cell among the above-mentioned at least one cell is received by the second communications node.  The fluctuation compensation time is based on a maximum fluctuation time of a route connecting the first and second communications nodes to each other as well as a bit rate of the first transmission line.  Finally, the original HDLC data is transferred to a second terminal from the second communications node via a second transmission line.
