  • Patent number: 7738482
    Abstract: The present invention describes a communications system having a first link partner and a second link partner that are connected by a communications link having at least four pairs of conductors. According to IEEE Standard 802.3 (e.g. Ethernet) for 1000Base-T, a data link is maintained (in a period absent data transmission) by sending idle signals over four pairs of conductors of the cable to maintain a logical connection. This idle signal scheme is replaced with an alternate idle signaling scheme that uses only two pairs of conductors to maintain a logical connection and therefore can operate with using lower power. The other two pairs of conductors of the four pairs of conductors are unused to maintain a logical connection absent data transfer, and therefore can be used to implement a Suspend Mode of operation. During Suspend Mode, the physical layer of each link partner powers down unnecessary circuitry so as to operate in a low power environment.

  • Patent number: 7685103
    Abstract: Disclosed is a technique for processing predicates in an iterator function. When an iterator function included in a statement is invoked, one or more predicates included in the statement are obtained. The one or more predicates are applied to a row of data. If applying the one or more predicates results in a match, the row of data is returned. If applying the one or more predicates does not result in a match, a search is performed for another row of data for which application of the one or more predicates results in a match. Also disclosed is a technique for processing predicates in which a statement including an iterator function and one or more predicates is received. A qualification descriptor that describes the one or more predicates and one or more functions that are to be used to evaluate the one or more predicates is created. Then, the iterator function is invoked one or more times, until receiving a done indicator from the iterator function.

  • Publication number: 20100067521
    Abstract: An internet protocol telephone includes a substrate having an input and an output that are capable of being connected to the internet protocol (IP) network. A relay is disposed on the substrate and is connected between the input and the output of the substrate. The relay includes first and second native FETs that have a threshold voltage of approximately zero volts. Therefore, the relay is nominally turned-on, even when little or no voltage (or power) is applied to the IP telephone substrate, as during the discovery mode of IP telephone operation. During discovery mode, The IP phone is configured to be responsive to extended link pulses and block data packets that are associated with legacy devices. Data packets have a higher signal duration and are more continuous than extended link pulses. The IP phone includes a switchable ground that is connected to the gates of the native devices, and is controlled by a rectifier and filter circuit that are connected to the substrate input.

  • Publication number: 20100034213
    Abstract: The invention allows data originating according to a first communications standard to be transmitted over a physical layer using a second communications standard. According to an embodiment of the invention, a data stream is received from a physical transmission medium that uses particular first communications standard. Next, a data type identification (DTID) is appended to each byte in the data stream, thereby creating a technology independent data stream having a particular bit rate. This bit rate is then matched to a different bit rate that corresponds to a second communications standard. The technology independent data stream is then transmitted over a physical transmission medium that uses the second communications standard.

  • Publication number: 20100002836
    Abstract: Flat panel images obtained during concurrent radiotherapy typically suffer from artefacts that relate to the pulses of MV energy. For a radiotherapeutic apparatus comprising a pulsed source of therapeutic radiation, a detector comprising control circuitry, an array of pixel elements, each having a signal output and an ‘enable’ input and being arranged to release a signal via the signal output upon being triggered by the enable input, and an interpreter arranged to receive the signal outputs of the pixel elements, the interpreter having a reset control, there are advantages in the control circuitry being adapted to reset the interpreter after a pulse of therapeutic radiation, prior to enabling at least one pixel of the array. Alternatively, the control circuitry can prompt a plurality of pulses by the pulsed source and then enable a plurality of pixels of the array. In effect, the therapeutic pulses are grouped into a short flurry of pulses.

  • Publication number: 20090288142
    Abstract: A device, system, and method are directed towards facilitating a registration of a user for a network service. In one embodiment, a server receives, from a user at a client device, user information including at least one text block. The server analyzes the text block to determine an authenticity value of the user information. The analysis may be based on the length of a lexicon of the text block, the size of a word such as the longest word in the text block, or the number of clauses in the text block. The analysis may be further based on expected values determined by such values in authentic text blocks of a similar nature. Based on the authenticity value, the system may allow the user to access the network service, disallow access to the network, allow conditional access, queue the registration application for further review, or take other actions.
