US Patent:

44082487, Oct 4, 1983

Filed:

Dec 30, 1981

Appl. No.:

6/335623

Inventors:

Raymond M. Bulley - Whippany NJ
William F. MacPherson - Wheaton IL
Robert F. Youhas - Parsippany NJ

Assignee:

Bell Telephone Laboratories, Incorporated - Murray Hill NJ

International Classification:

H02H 904

US Classification:

361 91

Abstract:

A protection circuit for communication equipment connected to a two conductor communication line includes a bridge rectifier having alternating current terminals connected to the conductors and to ground. The direct current terminals of the rectifier are connected to a device responsive to a range of predetermined voltage and current conditions in the conductors for reflecting foreign electrical energy.

Appl. No.:

5/648165

Inventors:

Charles Elmer Jones - Fairfield NJ
William Frederick MacPherson - Warren NJ

Assignee:

Bell Telephone Laboratories, Incorporated - Murray Hill NJ

International Classification:

H04M 1300

US Classification:

179 17E

Abstract:

A telephone ringer isolator for isolating ringers and extending ringing range on a multiparty telephone line or for range extension only on single party lines is disclosed. The circuit includes a detector circuit for detecting the direct current superimposed on an alternating current ringing signal. A pair of biasing circuits for transistors are enabled by a properly poled ringing signal appearing between tip and ring conductors. When the transistors are enabled, a capacitor is charged to trigger a silicon-controlled rectifier. When thus fired, the silicon-controlled rectifier enables a diode bridge gate to connect the ringer between one side of the telephone circuit and ground potential. Isolation between the input and output terminals is provided by the high collector resistance of the gating transistors.

International Classification:

G06F 3/0482
G06F 3/0483
G06T 11/20
G06Q 40/04

Abstract:

Disclosed are methods and systems of displaying graphical user interfaces (GUIs) that illustrate various offering analytics and insights. The GUI display selectable graphical components representing attributes of maturity bonds, wherein when a user interacts with a first graphical component corresponding to a first maturity bond, the server dynamically updates a second section of the GUI. The second section of the GUI displays time periods corresponding to a maturity date for the first maturity bond, wherein the server displays a vertical bar for each time period, a height of the vertical bar indicating a value of the maturity bond, wherein each vertical bar is divided into two areas a first area corresponding to a competitive sale of the first maturity bond, and a second area corresponding to a negotiated sale of the first maturity bond.
