    摘要： The information transfer method includes: determining an indicator of a start bit in a protection time slot or a preamble time slot of a laser, and establishing a communication channel according to the indicator of the start bit; inserting Operation Administration and Maintenance (OAM) information of a Long Reach-Passive Optical Network (LR-PON) device into an upstream frame sent to an Optical Line Terminal (OLT) device by the LR-PON device at a position indicated by the indicator of the start bit, and transporting the upstream frame to the OLT device through the communication channel. Therefore, OAM functions of the LR-PON device are extended, so that the OAM information can be transported by the LR-PON device independently, and OAM characteristics of the LR-PON device are enhanced. For example, PON protection is better supported, and the speed and success ratio of protection switching of a PON system are increased.

    摘要： The invention is directed to a system and method for controlling the flow of gas from a medical ventilator into a patient's lungs. The control system provides for a non-linear feedforward controller to correct for disturbances caused by back pressure at the outlet of the blower of the medical ventilator. For this purpose, a pressure transducer is provided to measure the back pressure. Additionally, the invention allows for a feedback controller to correct for the differences between the rate of the actual gas flow and the targeted gas flow rate. For this purpose a flow rate transducer is provided. The control system may account for each of the gas flow rate error and the back pressure disturbance to provide for a quick and accurate adjustment to achieve the targeted gas flow rate.
