Abstract: Remote configuration of an industrial or remote telemetry device using sound. Acoustic energy directed from a remote programming device to a remote industrial or telemetry device has tones indicating a request to establish communication. By directing further acoustic energy from the remote programming device to the remote industrial or telemetry device, the remote programming device requests information relating to a current configuration of the remote industrial or telemetry device. The remote industrial or telemetry device processes the tones to identify the request and replies with acoustic energy that has associated tones indicating the information relating to the current configuration of the remote industrial or telemetry device.

Abstract: Embodiments described herein provide for systems and methods for implementing a neural network architecture for spoof detection in audio signals. The neural network architecture contains a layers defining embedding extractors that extract embeddings from input audio signals. Spoofprint embeddings are generated for particular system enrollees to detect attempts to spoof the enrollee's voice. Optionally, voiceprint embeddings are generated for the system enrollees to recognize the enrollee's voice. The voiceprints are extracted using features related to the enrollee's voice. The spoofprints are extracted using features related to features of how the enrollee speaks and other artifacts. The spoofprints facilitate detection of efforts to fool voice biometrics using synthesized speech (e.g., deepfakes) that spoof and emulate the enrollee's voice.

Abstract: An exemplary audio enhancement system substantially eliminates latency by returning audio input signals in amplified form directly in the analog domain to the source, thereby reducing signal degradation and removing redundancy from digital and analog audio transmission and processing architectures.

Abstract: A smartphone case can include one or more piezotransductive materials (e.g., piezoelectric, piezomagnetic, piezoluminescent, etc.) positioned at one or more contact locations of the smartphone case. For example, a piezoelectric material can be positioned at multiple different locations of the smartphone case at which users may physically contact the smartphone case when holding the case. The piezoelectric material can generate an electric charge when pressure is applied to the material, and the generated electric charge can pass through an electromagnetic coil as an electric current to produce a magnetic field which one or more sensors (e.g., one or more magnetometers) of a smartphone that is housed within the smartphone case may be able to detect.

Abstract: A portable communications module (600) of FIG. 6 has an input (621) coupled to receive an incident signal. The input (621) split out a first audio channel containing a context audio track from the incident signal and directs the first audio channel along a first audio output path for selective audio output from a speaker (634, 620) either internally within or external to the module. The input (621)also directs a second audio channel in the incident signal to an RF audio transmitter chain for broadcast, the second audio channel comprising a composite audio signal from a plurality of audio tracks, each audio track embedded with a unique activation code that is present for substantially an entire duration of audio activity in each audio segment of each track. The input (621) is further arranged to apply a tone encoded signal in the incident signal to at least a tone decoder (640) in a data transmitter chain distinct from the audio transmitter chain (642).
