  • Publication number: 20130158565
    Abstract: A medical insertion device which may be used with or installed within an imaging system, such as magnetic resonance imaging (MRI). The medical insertion device can generally be used to retain, position and effect insertion of a medical instrument, for example a biopsy device or an ablation treatment device. The device can generally provide linear and/or angular degrees of freedom for positioning of the medical instrument prior to an insertion of the medical instrument. The medical insertion device includes a mounting arm, an interface connected to the mounting arm for interfacing with a medical instrument, a mechanism for movement of the medical instrument or a part of the medical instrument in an insertion direction, a carriage connected to a distal end of the mounting arm, and a pivot connection between the carriage and the distal end of the mounting arm to permit pitch or yaw of the mounting arm.

  • Patent number: 7889729
    Abstract: A system and method are provided for fairly distributing grants for access to switch outputs, through crossbars, between switch input channels. Crossbars are granted access between specified switch inputs and switch outputs, and the least recently used input channels are associated with selected switch outputs. A history of the previous channel transaction is maintained for each switch output, and channels are nominated in a rotation through a priority channel list. The present invention bid grant algorithm permits information packets to be transferred across a switch in the time between a bid submission and a bid grant.

  • Publication number: 20100170557
    Abstract: This invention relates to an improved high efficiency solar cell. The improvement comprises the addition of one or more silicon cells to surround at least a portion of the active region of the solar cell. Preferably, the silicon cells completely surround the active region of the solar cell. The silicon cells act as scavenger cells to absorb light that would otherwise not be absorbed by other components of the solar cell and to convert that energy to electricity.

  • Patent number: 7304987
    Abstract: A system and method are provided for resynchronizing backplane link management credit counters in a packet communications switch fabric. The method comprises: at an input port card ingress port, accepting information packets including cells and cell headers with destination information; modifying the destination information in the received cell headers; routing information packets between the input port card and output port cards on backplane data links through an intervening crossbar; at the input port card, maintaining a credit counter for each output port card channel; decrementing the counter in response to transmitting cells from the input port card; generating credits in response to transmitting cells from an output port card channel; sending the generated credits to increment the counter, using the modified destination information; and, using the generated credit flow to resynchronize the credit counter.

  • Patent number: 7263066
    Abstract: A credit-based system and method are provided for managing backplane traffic flow in a packet communications switch fabric. The method comprises: accepting information packets including cells and cell headers with destination information; modifying the destination information in the received cell headers; routing information packets between an input port card and output port cards on backplane data links through an intervening crossbar; at the input port card, maintaining a credit counter for each output port card channel; decrementing the counter in response to transmitting cells from the input port card; generating credits in response to transmitting cells from an output port card channel; and, using modified destination information, sending the generated credits to increment the counter. In some aspects, modifying the destination information in the received packet headers includes: extracting the output port card termination from the card field; and, inserting the input port card source in the card field.

  • Patent number: 7230947
    Abstract: A system and method are provided for cut-through packet routing in a packet communications switch fabric. The method comprises: accepting information packets addressed to a plurality of output port card egress ports at an input port card ingress port; routing information packets between port cards on backplane data links through an intervening crossbar; maintaining a credit counter for each port card egress destination, at the input port card; decrementing the counter in response to transmitting cells in a packet from the input port card; and, incrementing the counter in response to transmitting cells from the packet at the output port card. In some aspects of the method, accepting information includes buffering the packets in an ingress memory subsystem (iMS). Routing information includes the iMS transmitting buffered packets on a selected backplane data link. Decrementing the counter includes the iMS communicating with the iPQ in response to transmitting a cell.
