Utility
Detection of Blockage In a Porous Member
18 Nov 20
A method of detecting at least a blockage status in a porous member separating a measurement chamber of a device including a gas sensor positioned within the measurement chamber which is responsive to an analyte in an ambient environment to be sampled, includes emitting pressure waves from a pressure wave source which travel within the measurement chamber, measuring a first response via a first sensor responsive to pressure waves positioned at a first position within the measurement chamber, measuring a second response via a second sensor at a second position, different from the first position, and in fluid connection with the pressure wave source, determining the blockage status of the porous member based upon a functional relation of the first response and the second response.

Utility
Safety Device for Providing Output to an Individual Associated with a Hazardous Environment
16 Sep 20
Provided are computer-implemented methods that include receiving one or more messages from a device in a transmit state, including: a first message received at a first power level, the first message including data associated with a power level at which the first message was transmitted by the device in the transmit state, and a second message received at a second power level, the second message including data associated with a power level at which the second message was transmitted by the device in the transmit state; and determining a heading toward the device in the transmit state based on the first message and the second message.

Utility
Detection of Blockage In a Porous Member
27 May 20
A method of detecting at least a partial blockage in a porous member separating a first volume from a second volume or inner chamber of a device includes emitting pressure waves within the inner chamber by changing a volume of the inner chamber, measuring a response via a pressure sensor responsive to pressure waves positioned within the inner chamber, and determining if at least a partial blockage is present in the porous member based upon the response of the pressure sensor.

Utility
Sensor Interrogation
22 Apr 20
A method of operating a sensor system including at least one sensor for detecting an analyte gas and a control system includes electronically interrogating the sensor to determine the operational status thereof and upon determining that the operational status is non-conforming based upon one or more predetermined thresholds, the control system initiating an automated calibration of the sensor with the analyte gas or a simulant gas.

Utility
Determination of Sensor Operational Status Via Sensor Interrogation
1 Apr 20
A method of operating a gas sensor for a gas analyte including a sensing component includes, in a first mode, interrogating the sensor by periodically applying an electrical signal to the sensing component of the sensor, measuring sensor response to the electrical signal which is indicative of a sensitivity of the sensor each time the electrical signal is applied to the sensing component, determining whether one or more thresholds have been exceeded based upon the sensor response determined each time the electrical signal is applied to the sensing component, and entering a second mode, different from the first mode in analysis of the sensor response to the periodically applied electrical signals, if one or more thresholds are exceeded.
