Patent number: 11959997Abstract: A method of using a first device to locate a second device is disclosed. The first device, while in a first mode, transmits a first signal and receives a second signal comprising a reflection of the first signal by the second device. The first device determines, based on the received second signal, a position of the second device relative to the first device. The first device transitions to a second mode, and while in the second mode, receives a third signal from the second device. The first device determines, based on the third signal, an orientation of the second device relative to the first device. The first device comprises one or more receiving antennas, and the second device comprises one or more transmitting antennas. The third signal corresponds to a transmitting antenna of the second device.Type: GrantFiled: November 20, 2020Date of Patent: April 16, 2024Assignee: Magic Leap, Inc.Inventors: Koon Keong Shee, Jose Felix Rodriguez, Ricardo Arencibia, Aly H.

Publication number: 20230276428Abstract: Systems and methods for adaptive frequency hopping for reducing or avoiding electromagnetic interference between two radios operating in the same radio frequency (RF) band are provided. In one aspect, a host device, which includes first and second wireless radios and a hardware processor, can use adaptive frequency hopping among a plurality of RF channels to reduce interference. The device can control the first wireless radio to establish a first wireless connection with a terminal device via a first subset of channels, determine a set of performance statistics for the channels, and replace at least one of the first subset of the channels with a new channel within the plurality of channels based on the statistics. For example, a channel can be replaced if a packet error rate (PER) exceeds a threshold.Type: ApplicationFiled: February 10, 2023Publication date: August 31, 2023Inventors: Aly H.M. ALY, Cuthbert Martindale ALLEN, Humberto Eduardo GARCIA, Sumanth MURALI, Juan Leopoldo BALLEN, Christopher Michael LOPEZ

Publication number: 20220404622Abstract: Head-mounted augmented reality (AR) devices can track pose of a wearer's head to provide a three-dimensional virtual representation of objects in the wearer's environment. An electromagnetic (EM) tracking system can track head or body pose. A handheld user input device can include an EM emitter that generates an EM field, and the head-mounted AR device can include an EM sensor that senses the EM field. EM information from the sensor can be analyzed to determine location and/or orientation of the sensor and thereby the wearer's pose. The EM emitter and sensor may utilize time division multiplexing (TDM) or dynamic frequency tuning to operate at multiple frequencies. Voltage gain control may be implemented in the transmitter, rather than the sensor, allowing smaller and lighter weight sensor designs. The EM sensor can implement noise cancellation to reduce the level of EM interference generated by nearby audio speakers.Type: ApplicationFiled: August 24, 2022Publication date: December 22, 2022Inventors: Brian Bucknor, Christopher Lopez, Michael Janusz Woods, Aly H. M. Aly, James William Palmer, Evan Francis Rynk

Publication number: 20200412459Abstract: A method for adjusting transmitter output power (PTX) comprises sensing, by a proximity sensor communicatively coupled to a transmitting device, whether an object is proximate to the transmitting device. The method further comprises analyzing an image from a camera to determine whether the transmitting device is proximate to a portion of a human body, when the proximity sensor senses the object proximate to the transmitting device. Further, the method comprises adjusting the PTX of an antenna operatively coupled to the transmitting device to be less than or equal to a SAR threshold output power (PSARMAX), when it is determined that the transmitting device is proximate to the portion of the human body or when it cannot be determined whether the transmitting device is proximate to a portion of a human body.Type: ApplicationFiled: May 6, 2020Publication date: December 31, 2020Applicant: MAGIC LEAP, INC.Inventors: Shurhabeel Zamir SEYED, Koon Keong SHEE, Aly H.M.
