Abstract: In repairing soft tissue with a bone anchoring instrument (such as reattaching a tendon of a torn rotator cuff), the bone anchoring instrument may be used to anchor the soft tissue to a region of bone. The anchors inserted into the underlying bone may have one or more lengths of suture or wire attached thereto which may be tensioned independently of one another to affix the soft tissue to the bone by having a selector mechanism selectively engage and disengage ratcheted tensioning wheels from one another. Suture loading mechanisms may be employed for passing suture lengths into and/or through the anchors prior to deployment into the bone where such mechanisms may employ suture snares which are configured to reconfigure from an expanded shape through which suture lengths may be easily passed to a low-profile shape which secures the suture lengths within the snare.

Abstract: A knotless bone anchor and method for securing soft tissue, such as tendons, to bone, includes a plurality of discrete components. In one variation of the invention, the bone anchor includes a proximal toggle component, an intermediate plug component, and a distal sleeve component. Suture is looped around the plug component and once the anchor is actuated, the suture is compressed between the plug and the sleeve components. Advantageously, one or more of the components may be made of a biocompatible polymer. The polymeric components may be detachably joined to a drive shaft using a plurality of sacrificial fills. The sacrificial fills are broken or severed during deployment of the anchor. Related instruments and methods are also described.

Abstract: Particles (10) for controlling, treating, feeding of aquatic invertebrate filter feeding organisms such as mussels, clams, oysters and insect larvae comprising a biologically active ingredient (13) embedded within or surrounded by an innocuous carrier material (12). The organism effectively concentrates the active ingredient within its body by feeding on the particles, thereby reducing the total amount of active ingredient required to be used.

Abstract: A fixture for supporting a plurality of semiconductor chips during the thermal cycling of the chips, including a fluid-permeable bottom screen, a chip-cavity-defining plate supported against a top surface of the bottom screen, a lower attaching mechanism for attaching the chip-cavity-defining plate to the top surface of the bottom screen, and a removable fluid-permeable top screen attached to a top surface of the chip-cavity-defining plate to cover the plurality of holes and chips therein.

Abstract: A method of transferring a block of data from a first to a second circular buffer of a computer system. The method comprises notifying the DMA controller of the source and destination addresses for the transfer, the sizes of the circular buffers, and the size of the data block to be transferred. At the DMA controller, respective base and rollover addresses of the circular buffers are identified. Data is read from the first circular buffer starting at the source address, continuing until the rollover address is reached, and continuing from said buffer base address until the end of the block is reached. Data is written to the second circular buffer starting at the destination address, continuing until the rollover address is reached, and continuing from said buffer base address until the end of the block is reached.

Abstract: A system is provided for transferring data from a first network, which is packet based, to a second network. The system includes a physical layer input device, an input FIFO, a DMA controller for transferring data between addresses, an output FIFO, and a physical layer output device. The physical layer input device places beginning and end markers around packets in the input FIFO, and the DMA controller monitors the data which it transfers, and transfers data between said beginning and end markers, and ceases a transfer when an end of packet marker is reached.

Abstract: A Direct Memory Access (DMA) controller 5 for transferring data from a first to a second location under the control of a processor 7, the DMA controller 5 comprising at least three ports, each port being configurable to act as an input or output port of the DMA controller 5 and to be coupled to any one of the other ports.

Abstract: A method of debugging software arranged to run on a microcontroller for the purpose of controlling a macrocell associated with the microcontroller 1. The method comprises the steps of populating fields of a debugger application 3 using macrocell specific data read electronically from a database 4, said fields including at least a parameter name field and a parameter location field. One or more of the populated fields is displayed on a graphical user interface of the debugger application 3. User initiated debugging related instructions are relayed to the microcontroller 1 from the debugger application 3, whilst response data is received from the microcontroller 1 at the debugger application 3. The received response data is displayed to the user on the graphical user interface of the debugger application 3.
