Blumino: The First Fully Integrated Analog SiPM With On-Chip Time Conversion
Edoardo Charbon, Andrei Ardelean, Emanuele Ripiccini, Andrada Alexandra Muntean, Esteban Venialgo Araujo
Blumino is the first analog silicon photomultiplier with integrated amplifier, comparator and time-to-digital converter (TDC). The combination of a photodetector together with on-chip readout circuitry enables system-level advantages, such as internal para ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021Subjective evaluation of a spatialization feature for hearing aids by normal-hearing and hearing-impaired subjects
Hervé Lissek, Xavier Gigandet, Gilles André Courtois
Remote microphone systems significantly improve speech intelligibly performance offered by hearing aids. The voice of the speaker(s) is captured close to the mouth by a microphone, then wirelessly sent to the hearing aids. However, the sound is rendered in ...
AES2018Method and apparatus for presenting to a user of a wearable apparatus additional information related to an audio scene
Martin Vetterli, Ivan Dokmanic, Juri Ranieri
A method for presenting to a user of a wearable audio device a modified audio scene together with additional information related to the audio scene, comprising: capturing audio signals with a plurality of microphones; outputting an audio signal with a plur ...
2017Hybrid NRZ/Multi-Tone Signaling for High-Speed Low-Power Wireline Transceivers
Over the past few decades, incessant growth of Internet networking traffic and High-Performance Computing (HPC) has led to a tremendous demand for data bandwidth. Digital communication technologies combined with advanced integrated circuit scaling trends h ...
EPFL2016Hybrid NRZ/Multi-Tone Serial Data Transceiver for Multi-Drop Memory Interfaces
Seyed Armin Tajalli, Yusuf Leblebici, Kiarash Gharibdoust
A 7.5 Gb/s mixed NRZ/multi-tone transceiver for multi-drop bus (MDB) memory interfaces is designed and fabricated in 40 nm CMOS technology. Reducing the complexity of the equalization circuitry on the receiver (RX) side, the proposed architecture achieves ...
Institute of Electrical and Electronics Engineers2015Spatial Sound Localization via Multipath Euclidean Distance Matrix Recovery
Hervé Bourlard, Philip Neil Garner, Afsaneh Asaei, Mohammadjavad Taghizadeh, Saeid Haghighatshoar
A novel localization approach is proposed in order to find the position of an individual source using recordings of a single microphone in a reverberant enclosure. The multipath propagation is modeled by multiple virtual microphones as images of the actual ...
Ieee-Inst Electrical Electronics Engineers Inc2015Enabling Speech Applications using Ad Hoc Microphone Arrays
Microphone arrays are central players in hands-free speech interface applications. The main duty of a microphone array is capturing distant-talking speech with high quality. A microphone array can acquire the desired speech signals selectively by leading t ...
EPFL2015Nested Surface Coils for Multinuclear NMR
This article introduces the design of surface coils for multinuclear applications. The relative sensitivities of several NMR-visible nuclei of biological interest are considered, and the motivations to operate an RF coil at multiple frequencies, both seque ...
John Wiley & Sons2011Method And Device For Removing Echo In A Multi-Channel Audio Signal
Acoustic echo control and noise suppression is an important part of any "handsfree" telecommunication system, such as telephony or audio or video conferencing systems. Bandwidth and computational complexity constraints have prevented that stereo or multi-c ...
2008Observations on Multi-Band Asynchrony in Distant Speech Recordings
Whenever the speech signal is captured by a microphone distant from the user, the acoustic response of the room introduces significant distortions. To remove these distortions from the signal, solutions exist that greatly improve the ASR performance (what ...
