Patent number: 11967975Abstract: A method and apparatus that facilitates lossless data compression employing seed bits and recursive processing. The compression steps operate on the initial binary representation of the input digital data stream by representing the digital data stream using two data sets namely a rule data set and a seed data set, wherein the rules data is a dictionary, and the seed data is a unique binary string defined in the course of the recursive processing having a size that is less than the original data string.Type: GrantFiled: July 5, 2022Date of Patent: April 23, 2024Inventors: Eduin Esteban Hernandez Serna, Walter Andres Hernandez Serna

Publication number: 20240080609Abstract: Methods, systems, computer-readable media, and apparatuses for audio signal processing are presented. A device for audio signal processing includes a memory configured to store audio data and a processor coupled to the memory. The processor is configured to use an adaptation filter to adapt update filter coefficients of an update filter. The update filter coefficients are adapted based on a difference between an internal microphone signal and an output of the adaptation filter. An input of the adaptation filter is based on an external microphone signal. The processor is also configured to output an output signal from a hear-through filter. The hear-through filter includes the update filter and the adaptation filter. The processor is further configured to cause a loudspeaker to produce an audio output signal based on the output signal of the hear-through filter.Type: ApplicationFiled: November 10, 2023Publication date: March 7, 2024Inventors: Jacob Jon BEAN, Rogerio Guedes ALVES, Kamlesh LAKSHMINARAYANAN, Walter Andres ZULUAGA

Patent number: 11849274Abstract: Methods, systems, computer-readable media, and apparatuses for audio signal processing are presented. A device for audio signal processing includes a memory configured to store instructions and a processor configured to execute the instructions. When executed, the instructions cause the processor to receive an external microphone signal from a first microphone and produce a hear-through component that is based on the external microphone signal and hearing compensation data. The hearing compensation data is based on an audiogram of a particular user. The instructions, when executed, further cause the processor to cause a loudspeaker to produce an audio output signal based on the hear-through component.Type: GrantFiled: June 24, 2021Date of Patent: December 19, 2023Assignee: QUALCOMM IncorporatedInventors: Jacob Jon Bean, Rogerio Guedes Alves, Kamlesh Lakshminarayanan, Walter Andres Zuluaga
