    Abstract: Embodiments relate to a device (102) and method for determining a status of an environment (100) and/or a status or condition of a person (106) therein. The method may comprise: receiving (S402) an output of a sensor (204) to monitor said environment; commencing (S406) a time window after the sensor detects (S404) activity in the environment; upon expiry of the time window (S410), activating (S412) an active reflected wave detector (206) to measure wave reflections from the environment, the detector consuming more power in an activated state than the sensor in an activated state; and determining (S414) a status of the environment and/or of a person therein based on an output of the active detector indicative of one or more of the measured reflections. The method comprises delaying expiry of the time window in response to the sensor detecting activity in the environment during the time window.

    Abstract: A method is disclosed comprising: transmitting a pair of tracking signals, the pair of tracking signals including a first tracking signal and a second tracking signal; receiving a data set that is collected by using a sensor in a sensor array, the data set including: (i) a received first tracking signal that is generated by the sensor in response to receiving the first tracking signal, (ii) a received second tracking signal that is generated by the sensor in response to receiving the second tracking signal, and (iii) a received target signal; detecting a relative delay at which the first tracking signal and the second tracking signal are received by the sensor; removing the received first tracking signal and the received second tracking signal from the data set to produce a filtered data set; and providing the filtered data set and an indication of the relative delay to a beamformer.

    Abstract: Systems, methods, and computer program products for monitoring a level of product (14) in a reservoir (10, 130, 140, 190, 260) of a chemical dispensing system. A lid (22, 148, 216, 302, 358 ) configured to engage an opening (28, 136, 138, 146, 204, 352) of a container (12, 198, 354) includes a level sensor (26, 244, 272, 342, 386) having a transceiver (36) that transmits an output signal (38) and receives a portion of the output signal (38) reflected back (42) to the transceiver (36). The level sensor (26, 244, 272, 342, 386) determines an amount of the product (14) in the container (12, 198, 354) by comparing a characteristic of the reflected signal (42), such as time the reflected signal (42) was received, to the characteristic of the output signal (38), such as the time the output signal (38) was transmitted. The level sensor (26, 244, 272, 342, 386) may also determine the size of the container (12, 198, 354) based on the reflected signal (42), and take this size into account when determining the amount of product (14) in the container (12, 198, 354). The level sensor (26, 244, 272, 342, 386) transmits product level data to a mobile device (54) in response to receiving an interrogation signal (66) therefrom.

    Abstract: This invention relates to a method of reducing error in a SODAR system adapted to locate discontinuities in the atmosphere over a range extending away from an acoustic transmitter and receiver, the method comprising the steps of: measuring wind to determine either a substantially upwind direction or a substantially downwind direction relative to the transmitter; transmitting one or more forward or reverse acoustic chirps in the substantially upwind or downwind direction; receiving one or more acoustic echoes of the transmitted chirps; and processing the acoustic echoes to provide an indication of the discontinuities in the atmosphere over the range, thereby providing a wind shear profile.
