Publication number: 20170007169Abstract: 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).Type: ApplicationFiled: September 23, 2016Publication date: January 12, 2017Applicant: T&W Engineering A/SInventors: Tina Ahlberg LARSEN, Flemming Dahl JENSEN, Bent CLAUSEN, Erik Skov CHRISTENSEN, Soren KILSGAARD, Morten Holm JENSEN, Lars FRIIS

Patent number: 9232323Abstract: A hearing aid comprising a time domain codec. The codec comprises a decoder adapted to generate a decoded output signal based on an input quantization index and an encoder for generating an output quantization index based on an input signal, said encoder comprising said decoder and a predictor receiving an excitation signal derived from said decoder output signal and outputting a prediction signal. The output quantization index is determined by repeated decoding of the quantization indices in order to minimize the error between the input signal and the prediction signal, and the predictor uses a recursive autocorrelation estimate for the error minimization. The invention further provides a method of encoding an audio signal.Type: GrantFiled: March 26, 2012Date of Patent: January 5, 2016Assignee: Widex A/SInventors: Mike Lind Rank, Preben Kidmose, Michael Ungstrup, Morten Holm Jensen
