Publication number: 20240236567Abstract: In general, this disclosure describes various aspects of the techniques directed to an adaptive audio system for occupant aware vehicles. A device configured to reproduce a soundfield based on audio data within a vehicle may implement the techniques. The device may comprise a memory configured to store the audio data, and processing circuitry coupled to the memory. The processing circuitry may be configured to obtain, from an occupant monitoring system, a state of an occupant residing within a cabin of the vehicle, modify, based on the state of the occupant residing within the cabin of the vehicle, playback of the audio data within at least a portion of the cabin of the vehicle to obtain modified playback data for the audio data, and reproduce, based on the modified playback data, the soundfield.Type: ApplicationFiled: September 20, 2023Publication date: July 11, 2024Inventors: Asif Mohammad, Laxmi Rayapudi, Eddie Choy

Patent number: 10431211Abstract: An apparatus includes multiple microphones to generate audio signals based on sound of a far-field acoustic environment. The apparatus also includes a signal processing system to process the audio signals to generate at least one processed audio signal. The signal processing system is configured to update one or more processing parameters while operating in a first operational mode and is configured to use a static version of the one or more processing parameters while operating in the second operational mode. The apparatus further includes a keyword detection system to perform keyword detection based on the at least one processed audio signal to determine whether the sound includes an utterance corresponding to a keyword and, based on a result of the keyword detection, to send a control signal to the signal processing system to change an operational mode of the signal processing system.Type: GrantFiled: December 21, 2016Date of Patent: October 1, 2019Assignee: Qualcomm IncorporatedInventors: Lae-Hoon Kim, Erik Visser, Asif Mohammad, Ian Ernan Liu, Ye Jiang

Publication number: 20130195904Abstract: We identified regions of the HIV-1 proteome with high conservation, and low variant incidence. Such highly conserved sequences have direct relevance to the development of new-generation vaccines and diagnostic applications. The immune relevance of these sequences was assessed by their correlation to previously reported human T-cell epitopes and to recently identified human HIV-1 T-cell epitopes (identified using HLA transgenic mice). We identified (a) sequences specific to HIV-1 with no shared identity to other viruses and organisms, and (b) sequences that are specific to primate lentivirus group, with multiclade HIV-1 conservation.Type: ApplicationFiled: January 4, 2011Publication date: August 1, 2013Applicants: NATIONAL UNIVERSITY OF SINGAPORE, THE JOHNS HOPKINS UNIVERSITYInventors: J.

Publication number: 20130011427Abstract: Flaviviruses represent an increasing global public health issue, with no prophylactic and therapeutic formulations currently available for many of them. The combination of factors such as evolutionary change, global warming and wide range of animal hosts suggest the possible occurrence of Flavivirus strains with greater distribution and human pathogenicity. There is, thus, a need for greater understanding of viral protein sequences that function in the human immune responses. The evolutionary diversity of the reported sequences of major flaviviruses, such as dengue virus, yellow fever virus, Japanese encephalitis virus, and West Nile virus were analyzed with a combination of experimental and bioinformatics methodologies. The analysis of all reported sequences revealed that these species-specific peptide tags are highly conserved and are potential T-cell epitopes due to correspondence to known or predicted epitopes.Type: ApplicationFiled: December 16, 2010Publication date: January 10, 2013Applicant: THE JOHNS HOPKINS UNIVERSITYInventors: J. Thomas August, Tin Wee Tan, Asif Mohammad Khan
