A combination of a patient core temperature sensor and the dual-wavelength optical sensors in an ear probe or a body surface probe improves performance and allows for accurate computation of various vital signs from the photo-plethysmographic signal, such as arterial blood oxygenation (pulse oximetry), blood pressure, and others. A core body temperature is measured by two sensors, where the first contact sensor positioned on a resilient ear plug and the second sensor is on the external portion of the probe. The ear plug changes it's geometry after being inserted into an ear canal and compress both the first temperature sensor and the optical assembly against ear canal walls. The second temperature sensor provides a reference signal to a heater that is warmed up close to the body core temperature. The heater is connected to a common heat equalizer for the temperature sensor and the pulse oximeter. Temperature of the heat equalizer enhances the tissue perfusion to improve the optical sensors response. A pilot light is conducted to the ear canal via a contact illuminator, while a light transparent ear plug conducts the reflected lights back to the light detector.

The disclosed methods and devices incorporate a novel expandable bubble portion which provides superior fidelity to a listener while minimizing listener fatigue. The expandable bubble portion may be expanded through the transmission of low frequency audio signals or the pumping of a gas to the expandable bubble portion. In addition, embodiments of the acoustic device may be adapted to consistently and comfortably fit to any ear, providing for a variable, impedance matching acoustic seal to both the tympanic membrane and the audio transducer, respectively, while isolating the sound-vibration chamber within the driven bubble. This reduces the effect of gross audio transducer vibration excursions on the tympanic membrane and transmits the audio content in a manner which allows the ear to utilize its full inherent capabilities.

This invention is a wireless, speakerphone accessory that allows the user to be in either public or private communication with a remote electronic device like a mobile telephone. The accessory includes a detachable ear bud that can be worn in a user's ear so that only the user hears the audio signal being received. When the ear bud is coupled to the speakerphone accessory, the circuitry in the ear bud is used to control a loudspeaker and other components in the accessory so as to convert the combined device in to a speakerphone that may be heard by the user and others in his immediate vicinity. The speakerphone accessory optionally includes pockets for receiving rechargeable batteries, as well as utility pockets for holding spare components like ear sleeves. The invention not only offers the dual functionality of private and public operating modes, but serves as a self-retaining case to greatly reduce the chances that any of the components become lost.

A wearable wireless ear plug for providing a downloadable programmable personal alarm and method of construction are described. An alarm circuit is integrated with a self-contained power source. A randomly accessible memory is included to provide general purpose storage. A leadless interface is provided to externally receive a user-settable time interval and a programmable alarm tone, which are both stored into the memory. A clock circuit activates and times the user-settable time interval. A wireless interface receives a radio frequency alarm signal. An alarm circuit retrieves from the memory and generates the alarm tone through an in-ear speaker, which is triggered by either the clock circuit or the wireless interface respectively upon an expiry of the user-settable time interval and receipt of an alarm signal. The alarm circuit is housed in an ear plug shaped to house the in-ear speaker within an ear canal and to enclose the alarm circuit.

A non-vented shell earplug for insertion into the ear canal has multiple chambers configured as coupled acoustic resonators. Each chamber is provided with an acoustic element having inertia and resistance coupling the chamber to its neighbor to form multiple resonant chambers. The dimensions of the individual acoustic elements set the frequency response of the earplug, and determine the attenuation characteristics of the resonators. Unlike the single chamber resonator of the prior art, the multiple-resonator earplug provides attenuation in both low and high frequency segments of the noise spectrum.

Additionally, the present invention teaches placing loudspeaker and/or sound sensing transducer for sound communication purposes and active noise control within the earplug, with their sound field patterns directed into a chamber for coupling to the ear canal. The use of multiple resonators enhances the high frequency communications response of the earplug.

A kit for attenuation of noise includes a noise source audio transducer, two ear pieces, and a control unit. The two ear pieces have respective resilient bodies that engage outer portions of ear canals of respective ears of a user while respective in-ear transducers of the two ear pieces are respectively positioned in inner portions of the ear canals. The respective in-ear transducers detect discrepancies (e.g., incomplete superpositioning) between the noise and the anti-noise. The respective in-ear transducers optionally detect respective secondary path effects in the ear canals. The noise source audio transducer detects noise generated by a noise source (e.g., snoring noise). The control unit configures an adaptive filter based at least in part on an error signal, and optionally based in part on secondary path effects. The control unit generates signals representative of anti-noise. The two ear pieces produce the anti-noise responsive to the signals. The two ear pieces produce masking noise with sound level that varies in direct correlation with sound level of the noise generated by the noise source.
