  • Patent number: 10596336
    Abstract: A ventilation system provides patient-triggered support ventilation to a spontaneously breathing patient during ongoing high frequency ventilation (HFV), and has a pneumatic unit operated by a control computer for delivery of breathing gas in response to an effort to breathe by the patient, and an oscillator for superimposing high frequency oscillation onto the breathing gas. The system further includes a bioelectric sensor that measures a bioelectric signal indicative of the patient's efforts to breathe, and the control computer controls the delivery of breathing gas in response to the patient's effort to breathe, based on this bioelectric signal. The ventilation system is hence designed for neurally triggered support ventilation during ongoing HFV, which makes the trigger mechanism of the ventilation system more precise and robust compared to known trigger mechanisms of HFV ventilation systems.

  • Publication number: 20200068560
    Abstract: PUCCH resource determination for HARQ-ACK transmission in response to ePDCCH-scheduled PDSCH or ePDCCH-indicated SPS release in a TDD radio communication system. Downlink control information (DCI) is received in a downlink subframe via an Enhanced Physical Downlink Control Channel (ePDCCH). A resource index for a Physical Uplink Control Channel (PUCCH) resource is determined, based on the lowest enhanced Control Channel Element (eCCE) index of the received DCI, a device-specific offset value, and an index i that identifies the downlink subframe in a pre-determined set of one or more downlink subframes associated with an uplink subframe. The PUCCH resource is determined according to a formula that results in a sequential allocation of PUCCH resources in the uplink subframe with respect to the downlink subframes associated with the uplink subframe, for each of a plurality of sets of ePDCCH resources. HARQ feedback is transmitted in the uplink subframe, in the indexed PUCCH resource.
