  • Patent number: 10330644
    Abstract: Methods and systems are provided for conducting measurements of relative humidity using an ultrasonic sensor. In one example, a plurality of ultrasonic signals having different frequencies are transmitted from a single sensor, and attenuation values of reflected signals are determined only for those signals determined to have the same transit time from transmission to receipt, and where frequency of the plurality of ultrasonic signals may be changed responsive to an indication that the signals may be below a signal-to-noise threshold. In this way, by determining a difference between attenuation values between pairs of signals, where the signals comprise different frequencies and where the signals comprise the same transit times, relative humidity may be accurately determined.

  • Patent number: 10278368
    Abstract: An insect separating apparatus may include a sensor positioned to detect one or more insects when present within a test chamber. For example, the sensor may emit signals into the test chamber and receive reflected signals indicative of Doppler shifts caused by movement of the one or more insects. Based on information from the sensor, a computing device may determine a characteristic of the one or more insects in the chamber, such as a wing beat frequency, sex, or other characteristic. The computing device may instruct different responses based on the characteristic determined, such as activating an air mover to divert detected mosquitoes out of the test chamber in response to the determined characteristics matching those of female mosquitoes, or deactivating or maintaining the air mover in an inactive condition in response to the determined characteristics matching those of male mosquitoes, for example, to allow passage through the chamber into a collection receptacle.

  • Patent number: 10284208
    Abstract: An apparatus and method for frequency tuning/tracking between an electrical subsystem and a mechanical transducer subsystem is presented. An electromechanical transducer generates acoustic pulses as it is driven by a transmit signal from an electrical subsystem. As the transmit signal goes inactive, the settling behavior of the transducer is registered from which the difference in frequency between the resonance of the electromechanical transducer and the transmit signal frequency is determined and utilized for locking the electrical subsystem to the mechanical transducer subsystem by either tuning operating frequency of the electrical subsystem, or the mechanical transducer, to keep them matched (locked).

  • Patent number: 10284305
    Abstract: Systems and methods are disclosed allowing for spatially separated nodes to transmit data to a single remote master receiver node in a synchronized way. Slave nodes can send acoustic data so that it travels through water and arrives at the master node exactly timed so that the data bit appears in a predetermined time slot. The next time slot could be a data bit coming from another remote or slave node in another direction and at a different distance. This can be repeated for many nodes and the incoming bits will be received in a time division multiplexed fashion at the receiver or master node. The senders address and bit meaning are implicit due to the time slot in which they arrive. The assumption is that all nodes have accurate synchronized time as well as the ability to accurately estimate sound travel time between itself and any master node.
