Abstract: A humidification system can include a heater base, a humidification chamber, and a breathing circuit. A cartridge can be removably coupled to the heater base. The cartridge can include various sensors, probes, sensor wire connectors, heater wire connectors, and/or other features. The cartridge can include features configured to mate with corresponding features on the humidification chamber and the heater base. The cartridge includes a memory, such as an EEPROM, or other suitable storage device. When the cartridge is installed on the heater base, the memory is electrically connected to a processor and/or memory of the heater base. Various models of cartridges can be produced for use with different humidification chambers, breathing circuits, and/or therapies. A connector can be configured to couple an inspiratory conduit to an outlet port of the humidification chamber. The connector can provide a pneumatic connection to the outlet port and an electrical connection to the cartridge.

Abstract: A method is described for proving erasure of a memory. In the method a prover device receives a seed value from a verifier device. The prover device generates a series of data blocks starting with the seed value and a function. The series of data blocks is generated using the function and the seed to generate a first data block of the series of data blocks. Each subsequent data block is generated using the function and a preceding data block until a last data block of the series of data blocks is generated and written to the memory portion. The prover device writes the series of data blocks to the memory to overwrite all memory contents of a memory portion of the prover device. After the data blocks are written to the memory by the prover device, the prover device sends notification of memory erasure to the verifier device.

Abstract: Systems disclosed herein facilitate generating no-code applications and enable untrained users to develop no-code applications by using machine learning based recommendation systems to recommend no-code components to users. The systems can recommend no-code components during the development of a no-code application and/or after publication of a no-code application. The systems may recommend replacements of selected no-code components. Further, the systems may recommend configurations or alternative configurations of selected no-code components. The recommendations may be determined by using a prediction model trained using one or more machine learning models or algorithms. In some cases, the prediction model may be an ensemble model that uses the results of a plurality of prediction models or machine learning algorithms to make a recommendation.

Abstract: A device for providing respiratory gases comprises a blower configured to receive a first gas from a first gas flow path and generate a flow of a first gas provided through a first gases outlet of the blower; a second gas flow path configured to receive a flow of a second gas and provide the flow of the second gas through a second gases outlet; and a mixing chamber configured to receive a flow of the first gas from the first gases outlet and a flow of the second gas from the second gases outlet. The received gases are configured to mix in the mixing chamber to form a mixed gas. The received gases are configured to travel in a mixing flow direction in the mixing chamber towards a mixed gases inlet, wherein mixed gas exits the mixing chamber via the mixed gases inlet providing flow to a mixed gas flow path.

Abstract: The invention is directed to a method of monitoring oxygen at a patient to determine spontaneous breathing with a patent airway. The method includes the steps of providing a gas flow to a patient's airway, the gas flow including a predetermined fraction of oxygen, monitoring the fraction of oxygen at the patient's airway, generating a waveform representing the fraction of oxygen at the patient's airway, and determining whether the patient is spontaneously breathing with a patent airway based on the waveform.
