Publication number: 20220201421Abstract: A spatial audio processing system operable to enable audio signals to be spatially extracted from, or transmitted to, discrete locations within an acoustic space. Embodiments of the present disclosure enable an array of transducers being installed in an acoustic space to combine their signals via inverting physical and environmental models that are measured, learned, tracked, calculated, or estimated. The models may be combined with a whitening filter to establish a cooperative or non-cooperative information-bearing channel between the array and one or more discrete, targeted physical locations in the acoustic space by applying the inverted models with whitening filter to the received or transmitted acoustical signals. The spatial audio processing system may utilize a model of the combination of direct and indirect reflections in the acoustic space to receive or transmit acoustic information, regardless of ambient noise levels, reverberation, and positioning of physical interferers.Type: ApplicationFiled: March 9, 2022Publication date: June 23, 2022Inventors: James Keith McElveen, Gregory S. Nordlund, JR., Leonid Krasny

Patent number: 11019414Abstract: A wearable microphone array apparatus and system used as a directional audio system and as an assisted listening device. The present invention advances hearing aids and assisted listening devices to allow construction of a highly directional audio array that is wearable, natural sounding, and convenient to direct, as well as to provide directional cues to users who have partial or total loss of hearing in one or both ears. The advantages of the invention include simultaneously providing high gain, high directivity, high side lobe attenuation, and consistent beam width; providing significant beam forming at lower frequencies where substantial noises are present, particularly in noisy, reverberant environments; and allowing construction of a cost effective body-worn or body-carried directional audio device.Type: GrantFiled: March 31, 2020Date of Patent: May 25, 2021Assignee: Wave Sciences, LLCInventors: James Keith McElveen, Gregory S.

Patent number: 10298373Abstract: A radio base station, user equipment (UE), and method of control signaling in wireless communication systems. Control information is transferred from a base station to at least one UE, via a plurality of common pilot channels. A set of unique pilot sequences is predefined, and the base station assigns specific pilot sequences from the set of pilot sequences to specific common pilot channels, forming a pilot sequence assignment pattern representing specific control information. The UE, having knowledge of the relations between pilot sequence assignment patterns and control information, interprets the received pilot sequence assignment pattern as specific control information. The method is particularly well suited for broadcast type control information.Type: GrantFiled: September 21, 2017Date of Patent: May 21, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Yi-Pin Eric Wang, Jung-Fu Cheng, Stephen Grant, Karl J.

Publication number: 20150319712Abstract: A base station maximizes a uplink data transmission rate from multiple mobiles treated by the base station as a virtual single uplink transmitter. The base station identifies a set of mobile stations as a candidate transmitting set and determines a transmit power allowable from the mobile stations in the candidate transmitting set. A subset of those mobile stations in the candidate transmitting set is identified. Uplink data transmission rates are assigned and communicated to the subset of mobile stations in the candidate transmitting set so as to optimize a total number of bits processed by the base station associated with the uplink transmissions received from the subset of candidate mobile stations. The optimization may accomplish one or more objectives in addition to optimizing the total number of bits processed.Type: ApplicationFiled: June 2, 2015Publication date: November 5, 2015Inventors: Kumar Balachandran, Leonid Krasny

Patent number: 9042842Abstract: In a wireless network, plural downlink signals from plural base stations are transmitted to a terminal. The plural downlink signals all carry the same information to the terminal. The terminal provides feedback on the downlink channels. The feedback provides information on the taps of the channels. The amount of information fed back is constrained. Based on the feedback, transmission parameters of the downlink signals are adjusted. The process of transmitting, providing feedback, and adjusting the parameters continue so that the energy of the downlink signal is enhanced at the terminal location and suppressed elsewhere. Beam forming can be used to further suppress the energy signature at locations other than the terminal location.Type: GrantFiled: August 31, 2013Date of Patent: May 26, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Kumar Balachandran, Leonid Krasny
