US Patent:

40004120, Dec 28, 1976

Filed:

May 19, 1975

Appl. No.:

5/578913

Inventors:

Bruce David Rosenthal - Highland Park NJ
Andrew Gordon Francis Dingwall - Somerville NJ

Assignee:

RCA Corporation - New York NY

International Classification:

H03K 364
H03K 3353
H03K 1760

US Classification:

307208

Abstract:

Circuits for generating pulsating potentials and voltage levels outside the range of, and/or of greater magnitude than, the operating potential applied to the circuits. Each circuit includes first and second transistors for applying a first voltage to one plate of a capacitor and a second voltage to the other plate of the capacitor, during one time interval. During a subsequent time interval, the first and second transistors are turned off and a third transistor applies the second potential to the one plate of the capacitor. The change in the potential at the one plate of the capacitor is coupled to the other plate of the capacitor at which is produced an output potential outside the range of the first and second voltages. The potential difference between the first voltage and the output potential is greater in amplitude than the potential difference between the first and second voltages. The circuit may also include means alternately applying the first voltage and then the output potential to an output point for generating pulsating signals of greater amplitude than the magnitude of the applied potential.

Assignee:

RCA Corporation - New York NY

International Classification:

H03K 1700

US Classification:

307297

Abstract:

A circuit comprising first and second current amplifiers connected in a regenerative feedback loop and which includes a starting circuit. The latter initiates current flow in the loop and is automatically disconnected from the loop once normal operating conditions are reached therein.

Assignee:

RCA Corporation - New York NY

International Classification:

H03K 1940
H03K 1908

US Classification:

307214

Abstract:

A circuit, whose operating potential includes complementary pulsating signals, functions to produce quasi-static output signals which are virtually independent of the pulsations. An inverter circuit includes a first transistor connected between a first, fixed, operating voltage level and an output terminal and second and third transistors whose conduction paths are connected between the output terminal and, respectively, first and second sources of complementary pulsating signals whose voltages vary, in amplitude, between the first level and a second level. The same input signal is applied to the control electrodes of the second and third transistors whereby one of them always can, when turned on, clamp the output terminal to the second voltage level. The first transistor, when turned on, clamps the output to the first voltage level.

Abstract:

Implementations described herein relate to methods, systems, and computer-readable media to localize dynamic content. In some implementations, a computer-implemented method includes receiving visual content associated with a game from a first client locale, the visual content including text being represented at the first client locale by a first language, converting the text to generate translated text in at least a second language associated with a second client locale, and storing the translated text in a database in association with the visual content.

Abstract:

A video game method has steps for receiving, at a network-connected server providing video games, a request from a first player to enter a particular game, determining by software executing on a processor on the network-connected server, from a non-transitory medium, instances of the particular game already in progress, accessing stored information regarding friends of the first player, determining if one or more friends of the first player are engaged in one or more of the games already in progress, and directing the first player to a particular one of the games already in progress wherein one or more friends of the first player are engaged.

Abstract:

A VIP gaming service is provided through one or more servers providing games to players as members of the service, with one or more interactive interfaces executing on a web server, whereby players connected to the web server may select and configure games to play. Players connected to the server and logged in to the service are enabled by an interactive interface to purchase an ability to privatize an instance of playing a game, if a game developer has enabled the game to be hosted on a private server, and wherein privatizing the game selected as a VIP game enables the purchasing player to control entry of other players into the game in a specific instance of play, to alter circumstances and interactions in playing the game in the specific instance of play, and to lead the other players in the instance of playing the game.
