Abstract: Disclosed herein, among other things, are systems and methods for humidity detection for hearing device applications. A method includes calculating a capacitance between a terminal of a processor within a housing of an ear-wearable device and a designated ground plane within the housing. A temperature measurement is obtained from a sensor within the housing, and a humidity level is determined within the housing using the calculated capacitance and the obtained temperature measurement. The determined humidity level is compared to one or more predetermined humidity trigger levels, and a notification is sent to a wearer of the ear-wearable device conditioned on the comparison.

Abstract: A system to optimize energy usage associated with a fume hood is disclosed. The system may include a transceiver and a processor. The transceiver may be configured to receive inputs from a detection unit. The processor may obtain the inputs from the transceiver. Responsive to obtaining the inputs, the processor may determine that an extent of open state of a window associated with an enclosure may be greater than a predefined threshold for a predefined time duration and an absence of a user in proximity to the enclosure for the predefined time duration based on the inputs. The processor may further determine a total time duration the extent of open state is greater than the predefined threshold. Furthermore, the processor may calculate an estimated energy loss associated with the enclosure based on the extent of open state and the total time duration, and then output the estimated energy loss.

Abstract: Disclosed are methods to manipulate a given parametrized haptic curve in order to yield a smooth phase function for each acoustic transducer which minimizes unwanted parametric audio. Further, the impulse response of a haptic system describes the behavior of the system over time and can be convolved with a given input to simulate a response to that input. To produce a specific response, a deconvolution with the impulse response is necessary to generate an input.

Abstract: The system and method for wireless water leak detection provides for manual prevention of external action, such as an external alarm and/or valve shut-off, if a leak sensor can be reached by a respondent within a pre-set time threshold. Upon detection of a leak by a leak sensor, a local alarm, such as an audible alarm or the like, is initiated. Additionally, at the time of detection, a first time is recorded. A first alarm signal is transmitted from the leak sensor to a base station. The first alarm signal includes data representative of the recorded first time. If manual input is not received by the leak sensor within a pre-set time threshold measured from the first time, then the base station transmits a second alarm signal to at least one external device, and may further wirelessly transmit a shut-off signal to a valve controller for closing an associated valve.

Abstract: An aerial vehicle is programmed or configured to respond to reports of events or conditions within spaces of a facility. The aerial vehicle travels to a location of a reported event or condition and captures data using onboard sensors.

Alternatively, the aerial vehicle transmits a request for additional resources to be provided at the location, where necessary. A map of the location generated based on images or other data captured by the onboard sensors may be utilized for any purpose, such as to make one or more recommendations of products that are appropriate for use at the facility.
