Wearable apparatus for monitoring various physiological and environmental factors are provided. Real-time, noninvasive health and environmental monitors include a plurality of compact sensors integrated within small, low-profile devices, such as earpiece modules. Physiological and environmental data is collected and wirelessly transmitted into a wireless network, where the data is stored and / or processed.

A wireless headset for use with a separate communications device, such as a cellular telephone, includes automatic on / off capabilities to maximize battery life. By detecting a user's interaction, such as picking up the headset or placing it upon the user's body, the wireless headset automatically transitions from an inactive state to an active state. Techniques for automatic headset enabling include but are not limited to motion sensors, attitude or position sensors, proximity sensors, and contact sensors. These techniques may be used individually or in any combination. An internal timer allows the wireless headset to return to its inactive state a defined interval after cessation of movement or removal of the wireless headset. Including an optional sleep state further optimizes battery life. In the sleep state, only a portion of the wireless headset circuitry is enabled. Rather than transitioning from inactive to active, the headset transitions from inactive to sleep. In sleep, the headset periodically monitors for a signal from the separate communications device. Upon detection of such a signal, the wireless headset transitions to its active state, thereby providing full functionality to the user.

A listener can experience the sound of virtual loudspeakers over headphones with a level of realism that is difficult to distinguish from the real loudspeaker experience. Sets of personalized room impulse responses (PRIRs) are acquired for the loudspeaker sound sources over a limited number of listener head positions. The PRIRs are then used to transform an audio signal for the loudspeakers into a virtualized output for the headphones. Basing the transformation on the listener's head position, the system can adjust the transformation so that the virtual loudspeakers appear not to move as the listener moves the head.

A method and a control circuit for controlling an output of an audio signal of a battery-powered device are described.

The present invention provides a process for separating a good quality information signal from a noisy acoustic environment. The separation process uses a set of a least two spaced-apart transducers to capture noise and information components. The transducer signals, which have both a noise and information component, are received into a separation process. The separation process generates one channel that is substantially only noise, and another channel that is a combination of noise and information. An identification process is used to identify which channel has the information component. The noise signal is then used to set process characteristics that are applied to the combination signal to efficiently reduce or eliminate the noise component. In this way, the noise is effectively removed from the combination signal to generate a good qualify information signal. The information signal may be, for example, a speech signal, a seismic signal, a sonar signal, or other acoustic signal.

Embodiments of the invention relate to a feedback mechanism that informs a user of a communication device to adjust the volume, pitch, tone or other characteristic of his voice so as to compensate for noise in the surrounding environment. The feedback mechanism includes feedback circuitry that analyzes audio signals from the microphone and preferably from one or more additional environmental noise sensors. From the analysis, the feedback circuitry determines characteristics of the user's voice and characteristics of the environmental noise, and provides an analysis of how the user might modify his voice to best compensate for environmental noise. This analysis results in an indication to the user, such as through a vibration, a sound, or graphical indication on the device, which tells the user whether and to what extent the user should adjust a characteristic of his voice to best overcome such environmental noise.

The invention relates to an apparatus for sound reproduction of a sound information signal having spatial components, the apparatus includes: sound input means adapted to input the sound information signal; headtracking means for tracking a current head orientation of a listener listening to the sound information signal via sound emission sources and to produce a corresponding head orientation signal; sound information rotation means connected to the sound input means and the headtracking means and adapted to rotate said sound information signal to a substantially opposite degree to the degree of orientation of said current head orientation of the listener to produce a rotated sound information signal; and sound conversion means connected to the sound information rotation means for converting the rotated sound information signal to corresponding sound emission signals for outputting by the sound emission sources such that the spatial components of the sound information signal are substantially maintained in the presence of movement of the orientation of head of the listener.

This invention is a method for binaural localization using a cascade of resonators and anti-resonators to implement an HRTF (head-related transfer function). The spectrum of the cascade reproduces the magnitude spectrum of a desired HRTF. The proposed method provides a considerably more computationally efficient implementation of HRTF filters with no detectable deterioration of output quality while saving memory when storing a large quantity of HRTFs due to the parameterization of its resonators and anti-resonators. Finally, the method offers additional flexibility since the resonators and anti-resonators can be manipulated individually during the design process, making it possible to interpolate smoothly between HRTFs, reduce spectral coloring or achieve higher accuracy at perceptually relevant frequency regions. These HRTF are useful in stereo enhancement and multi-channel virtual surround simulation.

In representative embodiments, the present invention is directed to an at least partially in-the-canal module. The module may include a speaker module that generates audio signals from an electrical driving signal. The speaker module has a tubular body with a diameter that is smaller than the ear canal of the user. The speaker module also includes an arcuate raised ridge. A cushion tip of deformable material may be used to enclose the speaker module within a tubular portion that applies an elastic force to the arcuate raised ridge to prevent removal of the speaker from the cushion tip. Also, the tubular portion is longer than the speaker module to cause the cushion tip to deflect during navigation through the canal. Further, the tip portion of the cushion tip possesses sufficient structural rigidity to prevent the speaker from being pushed through the cushion tip during navigation through the canal.

Disclosed herein is a communications system implementing a headset wirelessly connected to a half-duplex communications device, such as a two-way radio or a radio-simulating cellular phone. The headset may incorporate a transmit / receive switch wherein a transmit signal is wirelessly transmitted from the headset to the communications device to direct the communications device to enter into a transmit mode. Alternatively, a wireless transmit / receive switch may be implemented separately from the wireless headset, where the wireless transmit / receive switch may be positioned in the proximity of the communications device and the headset and may be engaged by a user to direct the communications device to enter a transmit mode.

The present invention includes apparatuses and methods comprising a means for detecting the presence of speakers and microphones coupled to a portable multi-function device (such as Apple's iPhone™). In response, a portable multi-function device can adapt its output depending on the nature of the coupled headset device. In particular, a portable multi-function device containing the present invention can, upon detecting only one speaker in a coupled headset accessory device, combine the multiple channels of a stereo audio signal into a single mono audio signal. Likewise, a portable multi-function device containing the present invention can alert users to the absence of a coupled microphone.
