Patent number: 11949628Abstract: Technologies to improve wireless communications by on-body products are described. One device includes millimeter wave (mmWave) frequency front-end circuitry and a baseband processor with an Orthogonal Frequency Division Multiplexing (OFDM) physical (PHY) layer. The baseband processor determines received signal strength indicator (RSSI) value and phase value associated with a wireless channel in a mmWave frequency range. The baseband processor determines a state of motion of the device using the RSSI value and the phase value. The baseband processor sends data to the second device using a first subcarrier structure of the OFDM PHY layer, in response to the state of motion being a first state of motion. The baseband processor sends data to the second device using a second subcarrier structure of the OFDM physical layer, in response to the state motion being a second state of motion having more motion than the first state of motion.Type: GrantFiled: December 6, 2021Date of Patent: April 2, 2024Assignee: Amazon Technologies, Inc.Inventors: Cyril Arokiaraj Arool Emmanuel, Balamurugan Shanmugam

Patent number: 11310581Abstract: Technologies directed to reducing wireless earbud form factor and cost without compromising antenna performance are described. One wireless earbud includes a metal element that is a hybrid radiating element, touch element, and electrostatic discharge (ESD) trap. The metal element can include a first section coupled to a first ESD element, a second section that can include a circular element, and a third section coupled to a second ESD element. The wireless earbud can include touch circuitry coupled to the metal element to detect a presence of a conductive object in proximity to the metal element. The wireless earbud can include a radio that is parasitically coupled to the metal element and configured to apply a radio frequency signal to parasitically induce a current on the metal element that causes the metal element to radiate electromagnetic energy as a parasitic monopole element.Type: GrantFiled: March 16, 2020Date of Patent: April 19, 2022Assignee: Amazon Technologies, Inc.Inventors: Balamurugan Shanmugam, Tzung-I Lee

Patent number: 10931531Abstract: A first information handling system may determine a first bandwidth of a first connection between the first information handling system and a client information handling system. The first information handling system may also determine a second bandwidth of a second connection between a second information handling system and the client information handling system. The first information handling system may determine that the first bandwidth is greater than the second bandwidth. Based on the determination, the first information handling system may be designated as a VRRP master node based. Based on the designation as the VRRP master node, the first information handling system may control VRRP operation of the first and second information handling systems.Type: GrantFiled: April 22, 2019Date of Patent: February 23, 2021Assignee: Dell Products L.P.Inventors: Sampath Kumar Rajamanickam, Karthi Kaliyamoorthy, Balamurugan Shanmugam

Patent number: 10924391Abstract: Presented herein are systems and methods that provide traffic recover when virtual router redundancy protocol (VRRP) virtual media access control (VMAC) failures occur in a link aggregation group fabric environment. In one or more embodiments, automatic traffic recovery may be accomplished using internode link control messages to synchronize a VRRP VMAC failure that has been encountered by one LAG node with a LAG peer node. If a database associated with the failed LAG node comprises no entry that indicates that the failure scenario has previously occurred in the LAG peer node, a forwarding path entry rule may be generated to route traffic via the internode link, thereby, reducing data loss through routing failures and the like.Type: GrantFiled: April 3, 2019Date of Patent: February 16, 2021Assignee: DELL PRODUCTS L.P.Inventors: Karthi Kaliyamoorthy, Sampath Kumar Rajamanickam, Rajashekar Jayaraj, Balamurugan Shanmugam

Publication number: 20200322260Abstract: Presented herein are systems and methods that provide traffic recover when virtual router redundancy protocol (VRRP) virtual media access control (VMAC) failures occur in a link aggregation group fabric environment. In one or more embodiments, automatic traffic recovery may be accomplished using internode link control messages to synchronize a VRPP VMAC failure that has been encountered by one LAG node with a LAG peer node. If a database associated with the failed LAG node comprises no entry that indicates that the failure scenario has previously occurred in the LAG peer node, a forwarding path entry rule may be generated to route traffic via the internode link, thereby, reducing data loss through routing failures and the like.Type: ApplicationFiled: April 3, 2019Publication date: October 8, 2020Applicant: DELL PRODUCTS L.P.Inventors: Karthi KALIYAMOORTHY, Sampath Kumar RAJAMANICKAM, Rajashekar JAYARAJ, Balamurugan SHANMUGAM

Patent number: 10764666Abstract: An electronic device that includes a metal element arranged to at least partially cover a high impedance region associated with an antenna of the electronic device. The metal element presents a capacitive load to the antenna to mimic or replicate a capacitance placed on the antenna by a conductive element, such as a user's finger, coming in contact or close proximity to the antenna area. The capacitive load applied by the metal element tunes the antenna system for a large capacitance to resist antenna de-tuning and radio link interruption caused by the unintended user contact or near contact with the high impedance region of the antenna.Type: GrantFiled: August 13, 2018Date of Patent: September 1, 2020Assignee: Amazon Technologies, Inc.Inventors: Adrian Napoles, Balamurugan Shanmugam

Patent number: 10732764Abstract: A device includes a substrate and a touch control interface including touch control electrodes laminated onto the substrate and a touch controller electrically connected to each touch control electrode. The touch controller is configured to detect a change in a capacitance of a first touch control electrode to determine that a user is touching the first touch control electrode. The device may include a high-pass filter connected to the first touch control electrode and an impedance matching network electrically connected to the high-pass filter. The device includes a radio controller connected to the impedance matching network. The radio controller is configured to use the first touch control electrode as a first antenna to transmit and receive wireless signals. The optional impedance matching network may be configured to match an input impedance of the first touch control electrode to an output impedance of the radio controller.Type: GrantFiled: September 5, 2018Date of Patent: August 4, 2020Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Balamurugan Shanmugam, Sandeep Vuppu
