Patent number: 11985458Abstract: A first wireless speaker and microphone device paired with an information handling system comprising a microphone, speaker, wireless radio system for conducting a first pairing with the information handling system for wireless communications, and memory for storing a pairing profile for the first pairing. A microcontroller to operatively couple the first wireless speaker and microphone device to a second wireless speaker and microphone device by conducting a second pairing between the first and second wireless speaker and microphone devices, and cloning and transmitting the pairing profile from the first pairing to the second wireless speaker and microphone device. The first wireless speaker and microphone device to receive a switching command to stop audio transmission and reception at the first wireless speaker and microphone device to allow transmission and reception at the second wireless speaker and microphone device using a cloned wireless link established with the cloned pairing profile.Type: GrantFiled: April 29, 2022Date of Patent: May 14, 2024Assignee: DELL PRODUCTS LPInventors: Peng Lip Goh, Eng Kang Chng, Suet Chan Law

Patent number: 11978467Abstract: A speakerphone includes a processor, a memory device, a power management unit, a first microphone to receive audio waves, a second microphone to receive audio waves, and a third microphone to receive audio waves. The speakerphone may also include a digital signal processor (DSP) to detect a single-user mode activated at the speakerphone, process the audio waves received by the first microphone, second microphone, and third microphone to determine the wave phases of the audio waves received by the first microphone, second microphone, and third microphone, calculate a direction of a voice of a single user relative to the speakerphone; and process the voice of the single user and filter other voices detected by the first microphone, second microphone, and third microphone from the user's voice.Type: GrantFiled: July 21, 2022Date of Patent: May 7, 2024Assignee: DELL PRODUCTS LPInventors: Peng Lip Goh, Deeder M. Aurongzeb, Eng Kang Chng

Publication number: 20240029756Abstract: A speakerphone may include a memory device, a PMU, a first microphone, a second microphone, and a third microphone, each, to receive audio waves. The speakerphone also includes a DSP to process the audio waves received by the first microphone, second microphone, and third microphone to determine the wave phases of the audio waves received by the first microphone, second microphone, and third microphone to calculate a direction of a voice of a user relative to the speakerphone, lock in the voice direction of the user relative to the speakerphone, and process the voice of the user to detect characteristics of the user's voice and filter out background noises and background voices from outside an angular field coverage for the voice direction of the user.Type: ApplicationFiled: July 25, 2022Publication date: January 25, 2024Applicant: Dell Products, LPInventors: Peng Lip Goh, Eng Kang Chng, Fook Sin Choo, Deeder M.

Publication number: 20240031718Abstract: A headset presents audio sounds with first and second speakers disposed in first and second earcups that fit over first and second of an end user's ears. One ear cup adjusts with a greater travel distance relative to the other earcup so that the headset rests on the end user head with the one earcup raised above an ear and the other on an ear. A position sensor disposed in the headset detects the headset configuration to turn off audio at the speaker of the earcup that is displaced from the ear while increasing volume at the speaker of the earcup that remains over an ear. In addition, when only one ear is covered by an earcup, the audio presentation converts from stereo to monoaural.Type: ApplicationFiled: July 19, 2022Publication date: January 25, 2024Applicant: Dell Products L.P.Inventors: Eng Kang Chng, Karthikeyan Krishnakumar, Wong Hin Loong Justin

Patent number: 11656532Abstract: An information handling system peripheral camera ensures privacy with a cover that minimizes distance of a camera module to a front opening of the camera housing. For instance, opposing cover members rotate about geared ends that engage to translate rotation between the members, where the members meet over a camera opening to block capture of visual images and move to opposing sides to expose the camera module. In an alternative embodiment, a rotating shutter arrangement selectively covers the camera for security and also covers a microphone to provide security against unauthorized audible access through the camera. Selective covering and exposing of a camera module, infrared camera, microphone and user presence detection sensor support adaptive security at a camera based upon end user context.Type: GrantFiled: June 16, 2021Date of Patent: May 23, 2023Assignee: Dell Products L.P.Inventors: Peng Lip Goh, Suet Chan Law, Eng Kang Chng, Deeder M.
