Abstract: An optical transmission device for interconnecting an optical full duplex transmission line and a half duplex transmission line.  When a start bit of a data block of an electrical signal received from the half duplex transmission line is detected, a maintaining signal to maintain the same transmission direction is generated during which the data block can be transmitted.          An optical signal is received from the optical full duplex transmission line and converted into an electrical signal.  Similarly, a maintaining signal to maintain the same transmission direction is generated.          In response to either one of the two maintaining signals, passage or stopping of signals by a driver for sending out an electrical signal to the half duplex transmission line and a receiver for receiving an electrical signal from the half duplex transmission line are controlled.  Possible interference of data is prevented and the transmission direction is changed over in this manner.  Further, the level of an optical signal is monitored, and when the optical signal level becomes lower than a reference level, an abnormality warning data is transmitted succeeding to the data block.

Title: Apparatus for providing telephonic mass announcement service and methods for use therein
Inventor: LIBONATI MICHAEL G
IPC: H04Q11/04
Filed: 1990-08-02
Granted: 1995-07-04
Abstract: Apparatus for a telephone switch, e.g. a tandem switch, for providing a telephonic mass announcement service and methods for use therein in providing passive and/or interactive announcements as well as interactive mass announcement based custom call routing services. Specifically, mass announcements are provided by connecting an announcement circuit as one input to a time-space-time (T/S/T) switch located within a tandem telephone switch and permitting the central processor that controls the tandem switch to establish a time slot connection between that circuit and any caller.  Digitized announcements are stored in a main announcement store contained within the tandem switch.  Operationally, the central processors respond to each incoming call for a specific announcement by establishing a time slot connection between that announcement circuit and the caller through the T/S/T matrix switch, downloading this announcement from the main announcement store into the announcement circuit and thereafter instructing the announcement circuit to play the announcement over the time slot connection to the caller, and specifically over the caller's "receive" leg of the "four-wire" path established through the T/S/T switch.  For interactive mass announcements, the central processor connects a DTMF receiver to a time slot connection established through the T/S/T matrix switch to the caller's "transmit" leg of this "four-wire" path in order to obtain a digit(s) entered by the caller during playback of the announcement.  During an interactive announcement, the announcement circuit executes a specific script, typically involving a decision tree contained therein, associated with the announcement and, in response to the entered digit(s).

Title: Compression of signals for perceptual quality
Inventor: JAYANT NUGGEHALLY SAMPATH
IPC: H04B14/04
Filed: 1992-02-17
Granted: 1997-06-17
Abstract: Compression of signals is achieved through a simple decision of whether or not to encode certain frequency bands; not how well to encode all of the frequency bands. Based on the input signal and on a preselected perceptual model, a "just noticeable difference" (jnd) noise spectrum is computed. This spectrum is applied to a selector where it is used in the decision to select a chosen number of frequency bands of the input signal. The bands selected are the bands with the greatest energy relative to the jnd energy in the same band. Each of the selected bands is encoded and transmitted to the receiver. Both analog and digital realizations are presented.
