A method and system for decoding a biphase-mark input stream is disclosed. Aspects of the present invention include receiving an external biphase-mark input stream by a receiver module; recovering timing information from the input stream; decoding the input stream to generate decoded data and storing the decoded data in a data buffer; reading, by an audio out module, the decoded data from the data buffer at a rate determined by a programmable clock; using the timing information from the receiver module to calculate a sampling frequency of the input stream; and adjusting a frequency of the programmable clock to substantially match the sampling frequency so that the audio out module reads the decoded from the buffer at substantially the same rate that the receiver module inputs the decoded data into the data buffer.

A physical layer transceiver of a home network station connected to a telephone medium has an architecture enabling adaptation of detection circuitry based on received network signals to enable reliable recovery of data signals. The physical layer transceiver includes an input amplifier that amplifies network signals according to one of 128 gain settings set by a receiver gain control signal. A signal conditioning circuit includes an envelope detector configured for outputting an envelope of the amplified received signal, and an energy detector configured for outputting an energy signal of the amplified received signals. The envelope signal and the energy signal are supplied to slicer threshold circuits, configured for outputting noise, peak, data event and energy event signals based on noise threshold, peak threshold, data transition threshold, and energy threshold signals, respectively. A digital controller controls the input amplifier gain and the threshold values, and adjusts the gain and threshold values based on the noise event signal and the peak event signal within an access ID (AID) interval. Hence, the receiver can be optimized on a per-packet basis for receiving network signals by adjusting the receiver portion during the AID preamble phase of the data packet.

A network node has multiple physical layer devices (PHYs), multiple media access controllers (MACs), and means for gathering information regarding the capabilities of other nodes on the network. The node capability information may be gathered using hardware or software, and may involve gathering information from data frames received by the node, and/or from capability and status announcement frames received by the node. The node capability information gathered and the node topology determined may be utilized in selecting one of the MACs as an active MAC for monitoring a network medium, and/or in selecting one of the PHYs as an active PHY for transmission of frames onto the network medium. The PHYs of the interface in an exemplary embodiment are able to transmit and receive data frames or packets which are in accordance with different home phoneline networking alliance (HPNA) specifications, for example, HPNA 1. 0 and HPNA 2.

Methods and apparatus are provided for removing emboli during an angioplasty, stenting or surgical procedure comprising a catheter having a funnel-shaped occlusion balloon of uniform thickness disposed on a distal end of the catheter. The occlusion balloon is fused to the distal end so that it provides a substantially seamless flow transition into a working lumen of the catheter. Additionally, a distal edge of the occlusion balloon is configured to be in close proximity with an inner wall of a vessel to facilitate blood flow into the catheter and efficiently remove emboli.

A network interface system includes a memory system for managing data obtained via a system bus that supports split transactions. The memory system comprises a first memory for storing outgoing assembled data frames and associated control information prior to transfer of the outgoing data to the network, and an assembly memory that stores unassembled outgoing data from the bus. A memory control system stores the control information associated with pending bus read requests and also transfers outgoing data from the assembly memory to the first memory when all the outgoing data for a corresponding read request has been assembled.

A balloon catheter includes a catheter shaft, a balloon, and a guidewire lumen extending through the lumen. A core wire with a distal coil are positioned in the catheter shaft proximal of the balloon, and a hypotube is positioned in a longitudinally extending inflation lumen, to provide both flexibility and pushability to the catheter shaft.

A medical device for the treatment of a sinus opening includes a handle, a grooming sheath, a rail, a guide wire, a balloon catheter and a balloon catheter movement mechanism. A method for treating a sinus opening includes inserting a medical device for the treatment of a sinus opening partially into a patient's anatomy, positioning a guide wire operatively extending from a rail of the medical device into a sinus opening of the patient, advancing a balloon catheter from an annular lumen of the medical device and along both the rail of the medical device and the guide wire with a balloon catheter movement mechanism, and inflating the balloon catheter.
