A method for controlling breathing gas flow of a ventilator for assisted or controlled ventilation of a patient as a function of a tracheobronchial airway pressure of the patient. A ventilator tube, such as a tracheal tube or tracheostomy tube, can be introduced into a trachea of the patient and subjected to the breathing gas, and has an inflatable cuff and at least one lumen that is continuous from a distal end of the tube to a proximal end of the tube. An apparatus detects an airway pressure, in which the tracheobronchial airway pressure is ascertained by continuous or intermittent detection and evaluation of an intra-cuff pressure prevailing in the cuff of the tube inserted into the trachea. The breathing gas flow of the ventilator is controlled as a function of the intra-cuff pressure detected.

A system for expanding PCI Express (PCIe) compliant signals over a fiber optic medium with no latency. A standardized fiber optic transceiver is adapted to provide an optimal PCIe expansion over a fiber optic medium. Signal buffers are utilized to translate and fine-tune standardized PCIe traffic to a level of low voltage differential signaling (LVDS) that is comprehensible to a wide range of fiber optic transceivers over a wide range of interface bandwidths. The intended use for such a high-speed LVDS buffer is to strengthen and enable PCIe signals over metal (copper) cable or metal printed circuit board (PCB) traces for large PCBs, such as backplanes, server motherboards, etc. By disposing the PCIe buffer used for metal (copper) cable between the PCIe bus and the fiber optic transceiver, one can achieve the signal conditioning and translating required to allow PCIe signals to pass over the fiber optic medium.

The present disclosure is directed to controlling a sending of a single data stream from a sending endpoint to a receiving endpoint. Both of the endpoints each have multiple physical interfaces connecting each endpoint to one or more networks. A buffer size is selected for a buffer at the receiving endpoint, and an estimation is made by the receiving endpoint of a fill rate of the buffer. The estimated fill rate is then compared with a target fill rate. Feedback is then sent by the receiving endpoint over one or more of the physical interfaces instructing the sending endpoint to reduce or increase a rate at which data is being sent, if the estimated fill rate is more than the target fill rate or the estimated fill rate is less than the target fill rate, respectively. The splitting and sending of data is then adjusted according to the feedback.
