Abstract: Each of one or more unknown compounds are separated from a sample over a separation time period. Separated compounds are ionized, producing one or more compound precursor ions for each of the unknown compounds and a plurality of background precursor ions. A precursor ion mass spectrum is measured for the combined compound and background precursor ions at each time step of a plurality of time steps spread across the separation time period, producing a plurality of precursor ion mass spectra. One or more background precursor ions are selected from the plurality of precursor ion mass spectra that have a resolving power in a range below a threshold expected resolving power. A separation time is detected for an unknown compound when a decrease in an intensity measurement of the selected background precursor ions over a time period exceeds a threshold decrease in intensity with respect to time.

Abstract: A method includes obtaining video data for a first set of video files, generating processing job data for a first video processing job based on the video data, identifying a first processing server having a capacity for handling the first video processing job, sending, to the first processing server, the processing job data for the first video processing job and a first request to validate the video data, receiving, from the first processing server, validation testing results in connection with the first set of video files, determining first transcoding parameters for the first set of video files based on the validation testing results and output requirements data for the first video processing job, and sending, to the first processing server, a second request to generate an output video based on the first set of video files, the second request including an indication of the first transcoding parameters.

Abstract: A processor-implemented method for authenticating a login without a password. The method includes: receiving a request to authenticate a login, the request including a user identifier and excluding a password; based on the user identifier, identifying a device to be used to authenticate the login; and in response to determining that a login confirmation message has been received from the identified device, authenticating the login.

Abstract: In one aspect, the present disclosure describes a server-implemented method for authenticating a login without a password. The method includes: a) receiving, from a request initiator, a request to authenticate a login, the request including a user identifier; b) providing, to a device pre-registered for use in association with the user identifier, an acknowledgement request, the device being configured to generate a prompt in response to receiving the acknowledgment request, the prompt requesting input to authenticate the login; c) initiating a timer; d) determining that a login confirmation message has been received from the pre-registered device before expiration of the timer; and e) in response to determining that the login confirmation message has been received from the pre-registered device before expiration of the timer, providing an authentication acknowledgment message to the request initiator.

Abstract: A lung ventilator particularly adapted for use in weaning patients from dependence thereupon and includes an exhalation conduit through which the gas exhaled by the patient is passed. Both the rate of flow of gas passing through the exhalation conduit during each individual exhalation phase, and the minute volume of exhaled gases are monitored. If, during any given exhalation phase, the minute volume of exhaled gases should fall below a chosen threshold, indicating that the patient fails to breathe adequately, the ventilator is triggered to perform a mandatory ventilation cycle. The ventilator is inhibited from delivering mandatory breaths, however, until the rate of flow of exhaled gas in a given exhalation phase has reduced to the point which indicates that exhalation has ceased.

Abstract: A volume-cycled lung ventilator providing for both spontaneous breathing of a patient and intermittent mandatory ventilation, the invention provides two parallel inspiratory flow paths, one flow path including a demand valve for supplying gas to the patient during spontaneous breathing and the other flow path including a solenoid-operated inspiratory flow valve for providing intermittent mandatory breaths. The invention provides structure capable of adjusting the intervals between mandatory breaths, the volume of each such breath and the flow waveform of each such breath. An expiratory flow path including a fluid operated expiratory flow valve is further provided. A flow rate signal generator in the expiratory flow path acts to sense the rate of exhalation of the patient and is effective to inhibit the opening of the inspiratory flow valve unless the rate of exhalation is below a predetermined value.
