Abstract: Provided are computer-implemented systems and methods for a device that includes at least one processor programmed or configured to receive one or more messages from a device in an transmit state, the one or more messages comprising a first message received at a first power level, the first message comprising data associated with a power level at which the first message was transmitted by the transmitting device, and a second messages received at a second power level, the second message comprising data associated with a power level at which the second message was transmitted by the transmitting device. The processor is further configured to determine a heading toward the transmitting device based on the first message and the second message; and output data associated with an indication of the heading toward the transmitting device.

Abstract: 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.

Abstract: A safety helmet includes an outer shell configured for surrounding a head of a user, and an infrared reflective layer disposed in an interior of the outer shell. The infrared reflective layer is configured for reflecting at a least a portion of incident infrared radiation transmitted through the outer shell. The infrared reflective layer has infrared reflectivity of at least 40%. The safety helmet further may have an evaporative cooling pad positioned within a cavity defined by the inner surface of the outer shell. A method of manufacturing a safety helmet is also disclosed.

Abstract: A gas sensor device includes a sensing element including a heating element and electronic circuitry in connection with the heating element. The sensing element forms resistive element in a circuit of the electronic circuitry. The electronic circuity operates the sensing element in a trigger mode via a pulsed energy input to the heating element at a first duty cycle and in a primary mode via a pulsed energy input to the heating element at a second duty cycle, which is greater than the first duty cycle. The electronic circuitry is further configured to measure a response of the sensing element over time during each pulse of a plurality of pulses of the pulsed energy input. The primary mode is entered upon measurement of a value of a response at or above a threshold value in the trigger mode of operation.

Abstract: 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.

Abstract: A method of operating a sensing element including a heating element in operative connection with electronic circuitry, wherein the sensing element forms a resistive element in a circuit of the electronic circuitry, includes, in at least a first phase, activating the electronic circuitry to heat the sensing element to a temperature at which the sensing element is responsive to an analyte gas via energy input to the heating element in a pulsed manner. A constant resistance setpoint is set for the sensing element and energy through the circuit is variably controlled via the pulsed energy input toward achieving the constant resistance setpoint. The method further includes measuring a response of the sensing element over time to the pulsed energy input.
