International Classification:

H04M 1/00

US Classification:

379413, 37939901

Abstract:

A device and a method for detecting presence of service on a telephone line prior to and during activation of alternative service on the line. The method comprises performing a first voltage detection on a subscriber line (S), activating a subscriber line interface circuit (SLIC) if no pre-existing service is detected (S), the SLIC providing an interface between the subscriber line and a service provider, and performing a second voltage detection on the subscriber line after a usage-dependent time has elapsed (S), the time being determined by heuristics which consider several factors, including usage history of the line and time of day.

Abstract:

A system including a modem locally generates a web page based graphical User interface for display to a user on a PC using different standardized browser applications and enabling a User to control or configure system functions. A processing system supports Internet compatible bi-directional communication and employs a method for providing local access to processing system parameters. The method involves receiving a locally initiated User command requesting access to a web page and validating authorization of the User command. The method also involves generating an Internet compatible web page for display containing a system parameter associated with the bi-directional communication in response to the validated User command. The generated web page is locally accessible via a web browser resident in the processing system and supports interactive functions such as, (a) configuring the processing system, (b) requesting display of system parameters, (c) selecting a service billing option, and (d) assigning Internet addresses.

Brian Albert Wittman - Indianapolis IN, US

Assignee:

Thomson Licensing - Boulogne-Billancourt

International Classification:

G01R 19/00
G01R 29/26
G01R 23/20

US Classification:

324 7611, 324620, 324613

Abstract:

A method and apparatus are disclosed for detecting disturbances in an alternating current (AC) supply. A method includes a step of indicating a relationship between supplied AC voltage and a threshold voltage for at least a portion of each cycle of the supplied AC voltage. A circuit for detecting disturbances in supplied alternating current (AC) is provided. The circuit includes a threshold detector coupled to a source of supplied AC. The threshold detector provides a signal indicating a relationship of the supplied AC levels to a threshold level for at least a portion of each cycle of the supplied AC.

US Classification:

726 13, 726 22, 380266

Abstract:

Disclosed are a method and bi-directional communication device, such as a cable modem, router, bridge, or other communication device adapted to communicate via a network and having a firewall, for identifying those packets associated with inappropriate activity. The communication device includes at least one user discernable indicator associated with the firewall. The at least one user discernable indicator contemporaneously indicates that a number of packets associated with the inappropriate activity has exceeded a threshold level.

International Classification:

G01N 27/327

US Classification:

20440302

Abstract:

A test strip for analyzing a biological fluid using a test meter includes a biosensor to sense the biological fluid. The test strip includes contacts to communicate with the test meter and conductors connected to the contacts. The test strip further includes a combination of diodes, resistors, and short circuits arranged in various ways between the conductors. The test strip stores data based on a number of connections severed between the diodes, the resistors, the short circuits, and the conductors. The test meter reads the data and communicates with the biosensor via the contacts.

International Classification:

H04M 150

US Classification:

179 84VF

Abstract:

In a multifrequency generator providing tone signaling for a telephone, the common switching functions are performed by solid state switching circuitry (1200). Improved signal transfer between the telephone line and transmit and receive transducer of the telephone is provided by arranging the solid-state transmit and receive switches (1201, 1401) in a gain configuration to increase the level of the speech signal. The tone signals are digitally synthesized and use an integrated R-C oscillator (600) as a reference. Button down and button up debouncing of a contact closure signal from a single contact per button keypad is provided.

International Classification:

H04N 140

US Classification:

358446

Abstract:

Scanning equipment for a low-cost facsimile machine which includes a variable gain amplifier and a comparator circuit for correcting nonuniformities in lighting, lenses, light sensors and the like. Each line of a document being scanned is subdivided into a number of picture elements that individually suffer from different degrees of nonuniformity. Stored correction signals, associated with each picture element, are used by the variable gain amplifier and the comparator in processing an analog output signal from the line scanner to thereby correct nonuniformities. In one illustrative embodiment of the invention, the stored correction signals regulate the magnitude of the line scanner's analog output signal which is then compared with a fixed black/white threshold voltage. In another illustrative embodiment of the invention, the stored correction signals are used to generate a number of black/white threshold voltages which are then compared with the line scanner's analog output signal. In all embodiments, correction signals are set during a calibration procedure that uses an illumination level which corresponds to the threshold between black and white.
