  • Patent number: 6579281
    Abstract: An instrument stabilizer minimizes unwanted motion at the distal end of a surgical instrument by applying a damping force to the instrument. According to one embodiment, the instrument stabilizer preferably includes a cannula through which an instrument can extend, and a distal bushing adapted to contact the instrument. The instrument stabilizer also includes a proximal housing which includes a mechanism which applies a stabilizing or damping force to the proximal portion of the cannula. The mechanism which applies the force may be, by way of example, one or more of elastic bands, springs, struts, etc. When a surgical instrument is extended through the cannula and contacts the bushing, movement of the cannula and consequently the surgical instrument is damped by the stabilization force on the proximal portion of the cannula. In addition, a swivel device for angularly orienting the instrument stabilizer relative to a body of patient is also provided.

  • Patent number: 6567465
    Abstract: A DSL modem with a receiver and a transmitter includes an LDPC encoder which utilizes a generation matrix G which is derived from a substantially deterministic H matrix in order to generate redundant parity bits for a block of bits. The H matrix is determined by assigning “ones” of a first column Nj randomly or deterministically. Then, beginning with the second column, assignment of “ones” is carried out deterministically with each “1” in a previous ancestor column generating a “1” in the next descendant column based on the rule that a descendant is placed one position below or above an ancestor. As a result, descending or ascending diagonals are generated. When distributing “ones” in any given column, care is taken to ensure that no rectangles are generated in conjunction with other “ones” in the current column and previous columns. By avoiding generation of rectangles, diagonals are interrupted.

  • Patent number: 6546417
    Abstract: Electronic mail client software has a mailbox displayer which lists messages together with an icon for each message where the icon is associated with the MIME type of the message. Mail which contains a file attachment is listed in the inbox with an icon indicative of the type of file attached to the email. The mailbox displayer interprets the MIME type and selects the appropriate icon either from the icon registry in the OS or from a directory of icons maintained by the email client software. The mailbox displayer component preferably includes all of the functionality of state-of-the-art mailbox displayers and includes the functionality of looking to a directory of icons for display with information about the message based on the MIME type and subtype of the message. If there is no appropriate icon in the directory of icons, the mailbox displayer uses icon image data contained in a subpart of the MIME message if it is available. Otherwise, no icon or a generic icon is used.

  • Patent number: 6542551
    Abstract: The receiver of a PCM modem utilizes the V.90 TRN1d training signal for detecting whether any of the six slots of the received signal may be subject to alternating robbed bit signaling (ARBS), and what the alternating robbed bit signaling pattern may be. This is accomplished by accumulating the received level over a plurality of frames for each slot and by comparing the received levels for each slot to an average level for that slot. If the difference between the received levels and the average levels exceeds a threshold, the slot is determined to be subject to ARBS. Where a slot is subject to ARBS, DIL sequence signals for frames of the alternating robbed bit signaling slot having LSB=0 and LSB=1 are accumulated separately (if available) in order to generate two translation tables (TRT0, TRT1) for that slot. Where the DIL sequence is found only in the frames having the alternating robbed bit signaling slot having LSB=0 or having LSB=1, only one translation table can be generated.

  • Patent number: 6539023
    Abstract: An apparatus for handling back-to-back maintenance messages in extended superframe t1 telephone circuits includes a FIFO, a byte counter, and a message length register. According toga method of the invention, when messages are placed in the. FIFO, the byte counter counts the message length and places the message length in the message length register. A host controller is required to read the message length register in the time interval following complete receipt of a first message before complete receipt of a second message, but is only required to read the contents of the FIFO before it overflows. According to a presently preferred embodiment of the apparatus, a second register is provided for indicating the current depth of the FIFO. The second register sends an interrupt to the host controller when the contents of the FIFO exceed a threshold.
