Abstract: A system for determining a biometric parameter of a body, in particular for determining a physiological parameter of a body comprising blood perfused tissue, the system comprising: a housing; a radiation source provided at or in the housing, configured to emit radiation to a surface of the body; a radiation detector configured to detect radiation and to create output signal(s) related to the detected radiation, and configured to simultaneously detect radiation emitted to the surface of the body and radiation received from the body at a fixed distance from the radiation source or the body; and a controller configured to receive output signal(s) from the radiation detector and to determine the biometric parameter from the output signal(s), and configured to determine a relative movement between the body and the radiation source from at least a portion of the output signal(s).

Abstract: The present invention relates to a system for deriving information relating to a cavity in blood perfused tissue comprising a cavity having an inner surface, the system comprising a sensor comprising a housing and, in or at the housing, a first, a second and a third distance and/or movement sensor, the housing having an outer surface and being configured to be positioned in the cavity, the first distance and/or movement sensor being configured to sense a first distance or velocity from a first position and in a first direction and output a corresponding first output signal, the second distance and/or movement sensor being configured to sense a first distance or velocity from a second position and in a second direction and output a corresponding second output signal, the third distance and/or movement being configured to sense sensing a first distance or velocity from a third position and in a third direction and output a corresponding third output signal, where, when projected on to a predetermined plane, no

Abstract: A hearing aid module includes an elongated housing, an optical sensor module within the housing, an audio driver positioned within the housing adjacent the optical sensor module, and first and second light guides positioned near the audio driver. The module has a rectangular configuration with opposite first and second sides, opposite third and fourth sides, and opposite first and second ends. The first and second sides each include an opening. An ear tip is coupled to the housing first end and is configured to retain the module within the auditory canal. The first light guide guides light from an optical emitter through the opening in the housing first side and into skin of the auditory canal in a non-line of sight manner. The second light guide collects light from the skin of the auditory canal and directs the collected light to an optical detector in a non-line of sight manner.

Abstract: A hearing device such as a receiver-in-ear assembly. The assembly includes a housing having a cavity extending through the housing; an optical transducer mounted in the cavity within a thickness of the housing, the optical transducer being mounted on a circuit board layer such that a spacing exists between a side of the optical transducer and a sidewall of the cavity. The circuit board layer extends underneath the housing and touching the housing such that the optical transducer is held within the cavity without touching the housing. The assembly further includes a protective substance forming a shield over the optical transducer and the cavity, the protective substance configured to affect a field of view of the optical transducer.

Abstract: An assembly of a receiver and a microphone, such as for positioning in an ear canal of a person. The receiver and microphone are provided in an overlapping relationship to take up less space while being able to emit sound in one direction and receive sound from that direction. When the assembly if for use deep inside the ear canal of a person, the microphone may be very small, as it is exposed to very high sound levels.
