A heart rate detection apparatus includes a signal acquisition device for acquiring an intra-aural vibration wave signal and converting the intra-aural vibration wave signal into an intra-aural vibration electrical signal; and an arithmetic processing device for processing the intra-aural vibration electrical signal by computing to generate heart rate information. In the prior art, the heart rate detection apparatus cannot accurately and reliably detect the heart rate information due to the weak optical signal detected by a sensor. The heart rate detection apparatus acquires the intra-aural vibration wave signal to obtain the heart rate information, thus enabling the apparatus to accurately and reliably detect heart rate information.

Embodiments herein relate to ear-wearable systems and devices that can detect and/or take actions to prevent or alleviate stress related conditions such as post-traumatic stress disorder (PTSD) and the like. In an embodiment, an ear-wearable stress therapy system is included having a control circuit, a first sensor package, a microphone, and an electroacoustic transducer, wherein the electroacoustic transducer is in electrical communication with the control circuit. The ear-wearable stress therapy system can be configured to initiate administration of desensitization and reprocessing (DR) therapy to a device wearer. Other embodiments are also included herein.

This application relates to earbuds configured with one or more biometric sensors. At least one of the biometric sensors is configured to be pressed up against a portion of the tragus for making biometric measurements. In some embodiments, the housing of the earbud can be symmetric so that the earbud can be worn interchangeably in either a left or a right ear of a user. In such an embodiment, the earbud can include a sensor and circuitry configured to determine and alter operation of the earbud in accordance to which ear the earbud is determined to be sitting in.

An embodiment of the invention provides a wireless in-ear utility device that rests in the user's ear canal near the user's eardrum. The in-ear utility device may be configured in a variety of ways, including, but in no way limited to a smart in-ear utility device, a flexible personal sound amplification product, a personal music player, a “walkie-talkie” and the like.

An optical heart rate earphone includes a front housing, a circuit board assembly, a rear housing assembled to a rear end of the front housing, and a light pipe. The front housing has a sound tube. At least one portion of the sound tube forms at least one light transmission gap. The circuit board assembly includes a circuit board and at least one optical sensor. The at least one optical sensor is corresponding to the at least one light transmission gap. The light pipe has a circular base. At least one portion of a periphery of the base protrudes rearward to form at least one transmittance slice. The light pipe is assembled to the sound tube. The at least one transmittance slice is wedged in the at least one light transmission gap.

A smart glass including photoplethysmography and electrocardiogram sensors to determine a health condition of the user is provided. The smart glass includes a frame for holding two eyepieces, the frame having two nose pads to rest on a user's nose, and two arms to rest on two user's ears, a sensor mounted on at least one of the nose pads or the arms, and configured to collect an optical signal from a user's blood vessel, and a processor configured to obtain a waveform from the optical signal or the electrical signal, and to determine a cardiovascular parameter based on the waveform.

Provided according to embodiments of the invention are photoplethysmography probes designed for use on a user's nasal alar. Methods of using such photoplethysmography probes are also provided herein.

A body temperature measuring device and method. The body temperature measuring device includes: a soft and flexible stick-shaped shell, configured to be inserted into an external auditory canal of a testee in a process of measuring body temperature; a body temperature sensor configured to detect the body temperature; a master control chip connected with the body temperature sensor and configured to determine body temperature data corresponding to the body temperature; and a wireless communication module connected with the master control chip and configured to receive the body temperature data transmitted by the master control chip, and send the body temperature data to an external device. The body temperature sensor, the master control chip and the wireless commutation module are disposed in the stick-shaped shell.

An image generation system includes a region of interest identifying unit operable to identify a region of interest within a piece of content, the piece of content comprising one or more objects, and an image generation unit operable to generate an image for display comprising one or more of the one or more objects such that objects at a different visual depth to the region of interest are present in the generated image at a lower quality.

Methods and systems related to the field of gesture detection are disclosed herein. A system for a personal head wearable device includes a first electrode and a second electrode. The first electrode and the second electrode measure a bioelectric signal. The system further includes one or more non-transitory computer readable media storing instructions which, when executed by the system, cause the system to analyze the bioelectric signal to recognize a gesture signal in the bioelectric signal using a stored signature model for the gesture signal, and generate an interface signal upon recognizing the gesture signal in the bioelectric signal. The gesture signal is one of a double jaw clenching signal, a triple jaw clenching signal, and a long jaw clenching signal.
