Abstract: Remote monitoring of an area with a remote sensing device (100, 200, 300) encased in a rubber ball (302) is provided. A remote sensing device (100, 200, 300) is provided which receives a spoken description of a location of the remote sensing device and stores the spoken description as predetermined location information. The description can be received directly prior to deployment or wirelessly transmitted from another device (400). The remote sensing device can sense information related to its environment via a motion sensor (314), such as whether an intruder is located within a vicinity of the remote sensing device (100, 200, 300). The remote sensing device (100, 200, 300) can then transmit the predetermined location information and the environment information to the another device (400) in response to the sensing. In response to receipt, the other device (400) can render the predetermined location information and the environment information in an audible format.

Abstract: Systems, methods, and apparatus for facilitating multi-sensor signal optimization for speech communication are presented herein. A sensor component including acoustic sensors can be configured to detect sound and generate, based on the sound, first sound information associated with a first sensor of the acoustic sensors and second sound information associated with a second sensor of the acoustic sensors. Further, an audio processing component can be configured to generate filtered sound information based on the first sound information, the second sound information, and a spatial filter associated with the acoustic sensors; determine noise levels for the first sound information, the second sound information, and the filtered sound information; and generate output sound information based on a selection of one of the noise levels or a weighted combination of the noise levels.

Abstract: Boomless-microphones are described for a wireless helmet communicator with siren signal detection and classification capabilities. An acoustic component receives an audio signal and comprises a left acoustic sensor and a right acoustic sensor. The left acoustic sensor is mountable or attachable to the surface of a left wall of a helmet and the right acoustic sensor is mountable or attachable to the surface of a right wall. A speaker component can generate an echoless audio signal via signal inversion of the audio signal, outputs to a left speaker mountable or attachable to a left ear area of the helmet and a right speaker mountable or attachable to a right ear area of the helmet. A signal enhancement component can increase an intensity of the first audio signal associated with an emergency siren based on a determined proximity of an emitting emergency vehicle or emergency object to the device.

Abstract: With regards to a hearing assistive device, a the user's speech can be picked up by the microphone and feed through the speaker causing an acoustic feedback effect. The user may have to constantly adjust the volume of the hearing assistive device to achieve a more comfortable volume based on where the speech is coming from. Furthermore, the when the hearing assistive device experiences feedback, the amplification of the feedback can cause damage to the user's hearing. Therefore, mitigating the acoustic feedback effect of assistive hearing devices can generate a more efficient and comfortable hearing device. The acoustic feedback can be mitigated by leveraging a dynamic range controller and a howling detector which comprises a user interface and a status indicator.

Abstract: Systems and methods are presented for detecting a direction of an incoming projectile and determining a source location of the projectile. One or more resonant sensors (comprising a plate, piezo electric sensor, etc.) can be arranged, where shockwaves from the projectile (e.g., shockwaves from a bullet travelling at supersonic speeds) are incident upon the plate and cause the plate to resonate. The resonance causes an electrical signal to be generated by the piezo electric sensor (e.g., a piezo electric film sensor), the greater the degree of resonance in the plate, the higher the magnitude of signal generated by the piezo electric sensor. By comparing the magnitude of the piezo electric signals across the array of resonant sensors it is possible to determine a trajectory of the projectile and hence a location of the source of the projectile. Acoustic waves can also be generated by muzzle waves.

Abstract: For many hearing assistive devices, the user's speech is received at a larger amplitude signal than the speech of someone speaking to the user. Since the user's speech is also picked up by the microphone and feed through the speaker causing an acoustic feedback effect, the user may have to constantly adjust the volume of the hearing assistive device to achieve a more comfortable volume based on where the speech is coming from. Therefore, mitigating the acoustic feedback effect of assistive hearing devices can generate a more efficient and comfortable hearing device.

Abstract: Enhancing audio content based on application of different gains to different frequency bands of an audio signal is disclosed. Audio information contained in an input signal can undergo beamforming to provide an initial adjustment to the audio information, e.g., noise reduction, etc. In an embodiment beamforming can comprise double-beamforming in which first audio information is adjusted based on second audio information and the second audio information is adjusted based on the first audio information. Different gains can be applied to content in determined frequency bands, resulting in an amplified signal. In some embodiments, the gains can be related to hearing sensitivity of a listener, e.g., via a hearing sensitivity model. The amplified audio information from each frequency band can then be recombined. The recombined signal can be level limited and subjected to further digital and analog gains. The resulting output, e.g., enhanced audio, can be individually adapted for a listener.

Abstract: Disclosed is a graphical user interface operational on a portable device that allows users to test their minimum audio hearing level at various frequencies using a single button. The graphical user interface generates sound frequencies that are played to the user, one ear at a time. Starting from zero decibels, sound intensity levels are gradually increased to intensity levels perceptible by the user. The users indicate recognition of the sound frequency by interacting with the graphical user interface. The intensities of the sound pressure levels (SPLs) are registered as estimates of a user's hearing sensitivity at the tested frequency bands. The process is repeated at different frequency bands for each ear, and hearing levels for each ear established.
