International Classification:
H04M 908
US Classification:
37940608, 37940601
Abstract:
A non-linear processor for use in an echo canceller is set forth. The non-linear processor includes a center clipping digital filter receiving an echo compensated signal. The non-linear processor provides a center clipped output signal having non-linear thresholds at values of +T and -T. The value of T is dynamically dependent, at least in part, on echo return loss measurements. To limit the processors susceptibility to corruption from double-talk conditions, the non-linear processor inhibits the dynamic setting of the T value when a double-talk condition is present. Additionally, or in the alternative, the non-linear processor locks the value of the echo return loss measurement after a predetermined number of consecutive echo return loss measurements have values falling within a predetermined range of one another. Such locking further reduces the susceptibility of the non-linear processor to corruption from double-talk conditions.

International Classification:
G06Q 99/00 G06Q 20/00
US Classification:
705001000, 705016000
Abstract:
A central information processing system and method that issues receipts or tickets that can be securely validated at points of redemption. The method and system couple a client system with a server system and also couple at least one Radio Frequency IDentification (RFID) reader to the client system. The method and system read at least one identifier from a sheet with a RFID tag embedded therein with the RFID reader. The method and system also send the at least one identifier from the client system to the server system and receive from the server system at least one receipt image for printing on the paper with the RFID tag embedded therein. The method and system also print, at the client system, a receipt containing ticket information received from the server system. The server system further accepts at least one identifier that was read from a Radio Frequency Identification tag that was read from a sheet at the client system, records the at least one identifier, sends to the client system, in response to the accepting, at least one receipt image. Validation of the receipt or ticket includes reading, at a point of delivery, the at least one identifier from the Radio Frequency Identification tag and providing, in response to reading the at least one identifier, at least one of a good and a service.

US Classification:

Abstract:
A non-linear processor for use in an echo canceller is set forth. The non-linear processor includes a center clipping digital filter receiving an echo compensated signal. The non-linear processor provides a center clipped output signal having non-linear thresholds at values of +T. sub. NLP and -T. sub. NLP. The value of T. sub. NLP is dynamically dependent, at least in part, on echo return loss measurements. To limit the processor's susceptibility to corruption from double-talk conditions, the non-linear processor inhibits the dynamic setting of the T. sub. NLP value when a double-talk condition is present. Additionally, or in the alternative, the non-linear processor locks the value of the echo return loss measurement after a predetermined number of consecutive echo return loss measurements have values falling within a predetermined range of one another. Such locking further reduces the susceptibility of the non-linear processor to corruption from double-talk conditions.
Method And Apparatus For Providing A Multi-Pane Graphical Display With Information Associated With A Case Data Structure
Approaches are provided for an apparatus having an interface with an input and an output. The apparatus also includes a display device having a touch-sensitive user interface. The apparatus also includes a processor coupled to the interface and the display device. The processor is configured to display at the display device a first content pane, a second content pane, and a third content pane. The first content pane includes a case report received at the input of the interface. The case report represents characteristics of a case associated with an abnormality detected in an industrial machine or system. The second content pane includes a user input interface configured to receive a user input. The third content pane includes a response to the user input. The response is received at the input of the interface.
Method And Apparatus For Collaborative Threat Assessment

International Classification:
G08B 21/18 G05B 23/02 G07C 3/00
Abstract:
Approaches are provided for storing in a memory device a work plan and a case data structure associated with an industrial machine or system. The case data structure includes an impact field with an impact value, and an urgency field with an urgency value. A processor transmits via an output a case report to a plurality of local computing devices at a remote location. The case report is indicative of one or more characteristics of a case. The processor is further configured to receive via an input a plurality of transmissions from the plurality of local computing devices. Each of the transmissions are indicative of an assessed impact and an assessed urgency.

Lorry tragedy proves you're never alone in Glasgow
You can read it in the tweets of taxi driver David Farrell who offered to take anyone caught up in the crash home or to hospital for free. In the actions of the emergency services, many of them, no doubt, with difficult memories of the Clutha. Glasgow is heartbroken, yes, but what a heart.

Is the man from Dragon's Den Ireland's next president?
"I think the [real] winners, politically, will be Fianna Fil and Sinn Fin," said David Farrell, professor of politics at University College Dublin, saying many had written Fianna Fil off and that a victory for Mr Gallagher would be a major coup for the party.
