  • Publication number: 20170007169
    Abstract: A personal wearable monitor for monitoring a bio-electrical signal from a person. The monitor is adapted for detecting an upcoming seizure, and for providing an acoustical information signal. The monitor is provided with a first speaker (13) for providing the information signal, and a second speaker (14) is adapted for functioning as a microphone in testing if said first speaker is capable of providing a sound. The second speaker is also a back-up speaker. The monitor is adapted for providing a notification in the event that the second speaker (14) does not detect the generated sound from the first speaker (13).

  • Patent number: 9226082
    Abstract: A hearing aid (1) comprising a receiver (2) and at least one first microphone for transforming an acoustic signal surrounding a hearing aid user into an electrical signal, where the hearing aid comprises an ear plug part prepared for fitting tightly into the car canal (11) of a hearing aid user such that an inner volume is formed in the inner part of the ear canal between the car plug part and the car drum of the hearing aid user. The car plug part comprises a second microphone (3) arranged for transforming an acoustic signal in the volume into an electrical signal. The hearing aid comprises estimating means for estimating the effective size of the air leak between the inner volume and the surroundings based on the acoustical signal detected in said volume by said second microphone (3) from a known acoustical signal below 1000 Hz generated by the receiver. The hearing aid further comprises notification means for notifying the hearing aid user if the size range of the air leak is outside a predefined range.

  • Patent number: 9025802
    Abstract: A hearing aid comprises a microphone for transforming an acoustic signal surrounding a hearing aid user into an electrical signal, a signal processing means for processing the electrical signal into an electrical output signal and to a receiver (2) driven by the electrical output signal and generating an acoustical signal into the ear canal (11) of a hearing aid user. The hearing aid comprises an ear plug part (1) prepared for being arranged in the ear canal of a hearing aid user. The hearing aid comprises sound generation means for generating an acoustic guiding signal to be provided for a limited period through said receiver during insertion of the ear plug part into the ear canal, in order to be applied by the hearing aid user to optimize the positioning of the ear plug part (1). The invention further provides a method for guiding a hearing aid user during insertion of an ear plug.

  • Publication number: 20120257774
    Abstract: An earplug (100) for a hearing aid includes an ear canal body part (103) with a bore (106) and a sound output passage (107) in communication with the bore and leading to a sound output opening (105) and flanges (104a-d) surrounding said ear canal body part and adapted to engage a wall of an ear canal. The flanges are substantially disc shaped and have an axis of symmetry that is substantially parallel to the axis of symmetry of the bore of the ear canal body part. The invention further provides a hearing aid and a method of inserting a probe tube in an earplug.

  • Patent number: 6459886
    Abstract: A communication terminal, such as a handset, has a printed circuit board (PCB) sandwiched between a front cover and a back cover of the phone, and furthermore comprises at least one battery element placed between said printed circuit board and the back cover of the communication terminal. The at least one battery element and said printed circuit board are separated by a flexible and compressible partition wall. When the communication terminal is assembled, the wall provides bias between said at least one battery element and said printed circuit board.
