Abstract: An acoustic apparatus and method produces an acoustic signal in response to an electrical input signal applied to an acoustic receiver. The acoustic signal is converted to an electrical output signal that is proportional to a sound pressure of the acoustic signal, using an electro-acoustic transducer. In some embodiments the apparatus and method determine whether there is a change in the acoustic signal indicative of a change in an acoustic load coupled to the receiver by comparing the electrical output signal to reference information. The change in acoustic load, in one example, is attributable to ear wax accumulation in an output of the acoustic receiver or acoustic passage in the ear canal of a user or is attributable to seal leakage.

Abstract: A pre-distorted electrical excitation signal is generated for an acoustic transducer having an armature and a non-linear transfer characteristic by applying an electrical input signal (x) representative of a desired acoustic output to a computable non-linear function that is a function of the electrical input signal (x). When applied to an input of the transducer, the pre-distorted electrical excitation signal results in an improved acoustic output signal.

Abstract: Disclosed is a technique for providing one or more virtual machines or one or more software containers provided by cloud services to manage a horticultural operation. The techniques include transmitting, from the image dispatcher service, the image data to a first computing instance that executes a first subprocess of an image processing pipeline. Using the first subprocess of the image processing pipeline, partially processed image data is generated from the image data. The partially processed image data resulting from the first subprocess is then transmitted from the first computing instance to a second computing instance that executes a second subprocess of the image processing pipeline. Thereafter, a fully image processed image associated with the image data is produced via at least the second subprocess of the image processing pipeline.

More specifically, a captured image may be received from an image capture functions and analyzed to determine whether the captured image has sufficient information. In response to having sufficient information, an upload condition may be identified to upload the captured image to a remote data store. The captured image may be uploaded to the remote data store, based at least in part on the upload condition.

A sensor in the hearing device is configured to generate an output signal indicative of a state of the acoustic valve. An electrical circuit actuates the acoustic valve if the actual state is different than a desired state. The determination of the state of the acoustic valve can be done on the hearing device or on a remote device.

Abstract: The present disclosure describes techniques that facilitate a Governance Regulatory Compliance (C-GRC) controller that is configured to dynamically monitor and collate data associated with an agricultural operation for demonstrating compliance with an agricultural compliance plan. The C-GRC controller may act as a centralized server that dynamically monitors the cycle of agricultural activities for an agricultural product and in doing so, automates the governance of an agricultural compliance plan across a plurality of entities that are each responsible for one or more agricultural activities. The C-GRC controller may detect independent interactions conducted between a complying entity and a participating entity. These interactions may be intended to gather information relating to compliance of a pending task. In doing so, the C-GRC controller may update an agricultural compliance plan accordingly.

The membrane has a compliance that is 1 to 100 times a compliance of the acoustic device without the membrane, wherein the membrane prevents ingress of contaminants (e.g., solids, liquids or light) via the sound port while permitting propagation of the acoustic signal along the acoustic path without significant loss.

An image capture device is generally assigned to each plant, where images of each plant are captured frequently and periodically.

Alternatively, on the cloud based server side, a transfer manager software component manages file transfers based on available bandwidth, and provides a notification system reporting errors and violations of service level agreements.
