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.

Patent number: 11885871Abstract: An augmented reality device has a radar system that generates radar maps of locations of real world objects. An inertial measurement unit detects measurement values such as acceleration, gravitational force and inclination ranges. The values from the measurement unit drift over time. The radar maps are processed to determine fingerprints and the fingerprints are combined with the values from the measurement unit to store a pose estimate. Pose estimates at different times are compared to determine drift of the measurement unit. A measurement unit filter is adjusted to correct for the drift.Type: GrantFiled: May 24, 2019Date of Patent: January 30, 2024Assignee: Magic Leap, Inc.Inventors: Alexander Ilic, Martin Georg Zahnert, Koon Keong Shee

Publication number: 20230396881Abstract: A system and method for operating a depth sensor. A configuration operation can be performed by storing a first sequence of operation steps which define a first depth sensing mode of operation, and a second sequence of operation steps which define a second depth sensing mode of operation, in the memory. In response to a first request for depth measurements according to the first depth sensing mode of operation, the depth sensor can be operated in the first mode of operation by causing it to execute the first sequence of operation steps. In response to a second request for depth measurements according to the second depth sensing mode of operation, and without performing an additional configuration operation, the depth sensor can be operated in the second mode of operation by causing it to execute the second sequence of operation steps.Type: ApplicationFiled: August 22, 2023Publication date: December 7, 2023Inventors: Brian Keith SMITH, Koon Keong SHEE, Gregory Michael LINK

Patent number: 11444701Abstract: 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: GrantFiled: April 30, 2021Date of Patent: September 13, 2022Assignee: Magic Leap, Inc.Inventors: Shurhabeel Zamir Seyed, Koon Keong Shee, Aly Aly

Patent number: 11303809Abstract: A system and method for operating a sensor which has at least two modes of operation. The sensor may be provided with one or more common operation steps to be used in both a first mode of operation and a second mode of operation. The sensor may also be provided with one or more dummy operation steps to be used in the second mode of operation but not the first mode of operation. The dummy operation steps can convert the first mode of operation to the second mode of operation when used with the one or more common operation steps.Type: GrantFiled: September 17, 2019Date of Patent: April 12, 2022Assignee: Magic Leap, Inc.Inventors: Brian Keith Smith, Koon Keong Shee, Gregory Michael Link

Publication number: 20210302587Abstract: Techniques are disclosed for operating a time-of-flight (TOF) sensor. The TOF may be operated in a low power mode by repeatedly performing a low power mode sequence, which may include performing a depth frame by emitting light pulses, detecting reflected light pulses, and computing a depth map based on the detected reflected light pulses. Performing the low power mode sequence may also include performing an amplitude frame at least one time by emitting a light pulse, detecting a reflected light pulse, and computing an amplitude map based on the detected reflected light pulse. In response to determining that an activation condition is satisfied, the TOF may be switched to operate in a high accuracy mode by repeatedly performing a high accuracy mode sequence, which may include performing the depth frame multiple times .Type: ApplicationFiled: March 23, 2021Publication date: September 30, 2021Applicant: Magic Leap, Inc.Inventors: David Cohen, Elad Joseph, Eyal Preter, Paul Lacey, Koon Keong Shee, Evyatar Bluzer
