Patent number: 11183177Abstract: The present invention relates to a real-time voice recognition apparatus equipped with an application-specific integrated circuits (ASIC) chip and a smartphone, capable, by using one smartphone and one ASIC chip and without using a cloud computer, of assuring personal privacy, and, due to a short delay time, enabling real-time conversion of voice input signals into text for output. When one DRAM chip is optionally added to the real-time voice recognition apparatus, the number of neural network layers is increased thereby significantly improving accuracy of conversion of voice input signals into text.Type: GrantFiled: April 26, 2018Date of Patent: November 23, 2021Assignee: Postech Academy-Industry FoundationInventors: Hong June Park, Hyeon Kyu Noh, Won Cheol Lee, Kyeong Won Jeong

Patent number: 10993046Abstract: The present invention relates to a smartphone-based hearing aid which does not employ a separate power supply or digital signal processing device and instead has an analogue interface unit, configured with a single integrated circuit chip, connected between a plurality of microphones and a smartphone, thereby realizing a compact size, reducing the cost and enhancing the audio performance. Instead of employing a digital signal processing chip which is essentially used in the existing hearing aids or personal sound amplifiers, the smartphone-based hearing aid according to the present invention utilizes components such as a smartphone-embedded application processor (AP), RAM, digital-analogue converter, speaker and display and is therefore affordable.Type: GrantFiled: August 25, 2017Date of Patent: April 27, 2021Assignee: POSTECH ACADEMY-INDUSTRY FOUNDATIONInventors: Hong June Park, Seong Eun Cho, Ki Hwan Sung, Won Cheol Lee, Hyeon Kyu Noh, Im Soo Mok

Patent number: 9843867Abstract: The present invention relates to a microphone with a specific audible area using ultrasound wave, which emits an ultrasound wave toward a sound source positioned in a specific area within a desired distance and a desired direction from the microphone, and extracts a sound signal in an audible frequency range, generated by the sound source, from an ultrasound wave reflected and received from the sound source. The microphone with a specific audible area using ultrasound wave can limit the audible area to an area within a specific angle from a half line starting from the microphone and a specific distance from the microphone, such that a user can selectively hear a desired sound in a noisy environment. When the microphone is applied to a hearing aid, the user can hear only the audible sound generated by the sound source located within the specific audible area in front of the user with the surrounding noise removed.Type: GrantFiled: May 7, 2016Date of Patent: December 12, 2017Assignee: POSTECH ACADEMY-INDUSTRY FOUNDATIONInventors: Hong June Park, Dong Hee Yeo, Seong Eun Cho, Young Jae Jang, Kyeong Won Jeong

Patent number: 9392381Abstract: Disclosed is a hearing aid attached to a mobile electronic device. Elements forming the hearing aid are separated into a main hearing aid device and a sub-hearing aid device. The main hearing aid device is attached to the casing of a mobile electronic device and connected to the mobile electronic device through a wired cable, and the sub-hearing aid device is placed in an ear of a user. Other people rarely notice that a user uses the hearing aid because the main hearing aid device is mounted on the casing of a mobile electronic device. The hearing aid is supplied with power from the battery of the mobile electronic device, and has the same size as the casing of the mobile electronic device. Accordingly, a beamforming operation through a microphone array is possible, and use convenience and a level of satisfaction of the hearing aid can be improved.Type: GrantFiled: July 9, 2015Date of Patent: July 12, 2016Assignee: POSTECH ACADEMY-INDUSTRY FOUNDATIONInventors: Hong June Park, Seong Eun Cho, Dong Hee Yeo, Young Jae Jang, Hyeon Kyu Noh, Sang Hu Park

Publication number: 20150293636Abstract: The present invention relates to a sensor circuit method for securing a sufficient Signal to Noise Ratio (SNR) by reducing the influence of noise induced from a sensor element which appears in the final output signal of a reception unit although an input signal having a relatively small amplitude is used in a sensing apparatus in which a time-periodic signal having a relatively higher frequency as compared with the speed of change of a behavior of a user or a movement of an object to be sensed, such as a capacitive sensor or an inductive sensor, is used as an input signal. Power consumption of a touch sensor chip can be reduced even without increasing the amplitude of a touch sensor panel driving signal, and a production cost for a touch sensor chip can be reduced by removing a high voltage driver.Type: ApplicationFiled: December 4, 2013Publication date: October 15, 2015Applicant: POSTECH ACADEMY-INDUSTRY FOUNDATIONInventors: Hong June Park, Sang Su Lee, Dong Hee Yeo, Jae Seung Lee
