Abstract: A dual-use support cushion includes a seat cushion side and a back cushion side, with the seat cushion side configured to provide seat support and the back cushion side configured to provide back support. The dual-use pillow is an all-in-one design that allows the owner to choose between using the dual-use support cushion as back support or as a seat support and the owner can manually flip the cushion depending on what side is more appropriate for the user at any given moment. The dual-use support cushion provides, in a single item, the option of sitting on the cushion, and the option for using the same cushion, after relocation of the cushion, for back support.

Abstract: In a method of measuring packet loss, a flow of packets is identified at first and second locations in a network. The packets in the flow are counted at each of the first and second locations to provide first and second packet counts, respectively. When a trigger packet in the flow is identified at each of the first and second locations, the first and second packet counts are latched to provide latched first and second packet counts corresponding to same packets in the flow. The latched first and second packet counts are compared to measure packet loss between the first and second locations.

Abstract: A buffer to buffer credit recovery mechanism is disclosed in which the ports involved in the credit recovery operation are synchronized while credit recovery is being enabled and during a credit recovery operation when credit recovery parameters are being reset. Buffer to buffer credit recovery involves exchanging primitive control signals and parameters during the login sequence to enable credit recovery. Once credit is lost; there may be a need for resetting a link to reset the credit recovery counters and BB credits. Both of these processes require synchronization between the ports involved in the credit recovery mechanism. This synchronization is achieved by enabling credit recovery during the Link Reset protocol negotiation and ensuring that no frames or R_RDYs are exchanged during the procedure.

Abstract: Clock data recovery (CDR) circuitry of a high-speed serial interface on a programmable integrated circuit device toggles, during the electrical idle period of the receiver of the interface, between its “lock-to-reference” (“LTR”) state and its normal “lock-to-data” (“LTD”) state. Whenever during this toggling mode the CDR circuitry toggles to the LTD state, it remains in that state for a predetermined interval and then returns to the LTR state, unless, while it is in the LTD state, it receives a signal from elsewhere in the receiver that data have been received and byte synchronization has occurred. The predetermined toggling interval preferably is long enough to obtain an LTR lock to minimize frequency drift, but short enough to avoid unnecessary delay in detection of the synchronization signal. Preferably, this interval is programmable by the user within limits determined by the characterization of the programmable device. Unreliable analog signal detection is thereby avoided.

Abstract: Structures and methods to facilitate channel bundling are disclosed. In one embodiment, signal distribution circuitry includes a data path with at least two registers coupled to adjacent sets of data channels in a bundle of data channel sets. In another embodiment, self-switch circuits allow channels in a bundle of channel-sets to switch from bundle-wide signals to locally generated signals after the bundle-wide signals have been synchronously distributed to all channel sets in the bundle. In a particular embodiment, signal distribution circuitry is used to distribute a divided clock signal. In another particular embodiment, signal distribution circuitry is used to distribute enable signals for first-in first-out circuits (“FIFOs”) located in channels of each data channel set in a channel set bundle. In a particular aspect of an embodiment, FIFO read and write operations across a channel set bundle are initiated such that a difference between read and write pointer signals is the same in each channel set.

Abstract: A method of extracting network information first receives an initial link address (102) and retrieves a file (104) associated with the initial link address. The file is then parsed (106) to find a hyper text link. Next it is determined (108) if the hyper text link has a link address that contains the network address as a root. When the link address contains the initial link address as the root, a link file associated with the link address is retrieved (110).
