  • Patent number: 8276011
    Abstract: A system and method for tunneling control over a MAC/PHY interface for legacy ASIC support. Energy efficient Ethernet control or status information can be communicated over a MAC/PHY interface using control codes that are embedded in sequence ordered sets. These sequence ordered sets would not affect the data flow and can be tunneled within an existing interface (e.g., XAUI, XFI, xxMII or derivative interfaces) without generating errors.

  • Patent number: 8019686
    Abstract: A method and system allows multiple and simultaneous use of a pre-paid calling card. A call management system allows for the completion of multiple calls under one pre-paid calling card account number. Depending on the number of concurrent users, a billing system assigns a portion of the total number of available service units to individualized user accounts. The individualized accounts are debited according to the rate charges for each of the calls and are initially assigned an account balance that allows all concurrent users with the same amount of talk time.

  • Publication number: 20070120543
    Abstract: Flexible power converter and simplified process controller capable of being configured for a variety of applications with minimal effort. The power converter has a plurality of filtered half-bridges that can be configured for multiple topologies. The process controller can be adjusted through a timing parameter to process the configured feedback signal. External settings or serial port configuration enable stand-alone or processor-based operation. The invention may be quickly and easily applied as a versatile power supply, motor driver, thermal regulator, or controller for Lighting and flow applications. The flexible power converter and simplified process controller reduces development time and cost, reduces parts count and cost, and improves performance and reliability of power and control systems.

  • Patent number: 7027986
    Abstract: A method and an apparatus for providing automated speech-to-text encoding and decoding for hearing-impaired persons. A broadband subscriber terminal interfaces to: (a) a network to convey speech packets thereover, (b) a telephone to convey speech information, and (c) a display device to display textual information of spoken words. A speech buffer in the subscriber terminal receives speech data and a processor decodes and displays textual representations of speech on the display device. A database stores voice and/or speech patterns that are used by a speech analyzer to recognize an incoming caller and to associate a name or characteristic (e.g., male or female) with the incoming call. A tonal and inflection analyzer analyzes speech to add punctuation to the displayed text. A detector, such as a DTMF detector, responds to subscriber inputs to activate/deactivate speech recognition or other functions.

  • Publication number: 20060031148
    Abstract: A method of managing inventory may include using a handheld scanning device to locate one or more inventory items on a retail display. The method may further include scanning the identification symbols of inventory items on a retail display to determine the type of the scanned item. An associated apparatus may include a communication interface to receive information from a remote database and to send information to a remote server. The received information may include predetermined information about proper locations for individual inventory items on the retail display, thereby reducing the need to manually determine the proper locations of multiple inventory items, which may be, for example, greeting cards on a retail store display.
