Patent number: 11199425Abstract: Magnetic sensing technology can be used to detect changes, or disturbances (e.g., changes in magnetic field strength), in magnetic fields and can be used to measure the precise location/positioning of an electronic device in proximity to a magnetic source. In order to avoid interference by earth's static magnetic field, a modulated magnetic field can be used for magnetic based proximity sensing. Received modulated magnetic field signals can be demodulated to determine a received magnetic field strength. A drive current of a magnetic transmitter coil can be varied to maintain the detected magnetic field strength at a target value or within a desirable range. The drive current can also be varied to remain below a burnout current level that can cause damage to the transmitter coil.Type: GrantFiled: September 26, 2019Date of Patent: December 14, 2021Assignee: Apple Inc.Inventors: Savas Gider, Jian Guo, John Greer Elias

Patent number: 11181807Abstract: Apparatus and associated methods relate to ranging of objects in a scene based on difference images indicative of only objects in the scene that have ranges within a subrange. The difference images are calculated by taking differences of two images, each of which captures light reflected by objects in the scene that have ranges within range domains that are different from one another. Thus, each of the difference images includes light reflected by only those objects located at ranges that are included in one of the range domains but not the other. These range domains are controlled by the timing of operation of a fast shutter. In some embodiments, the fast shutter includes an electro-optical modulator between two polarizing filters. The electro-optical modulator can rapidly change the polarization of the light transmitted therethrough such that the second polarizing filter either transmits or blocks the light.Type: GrantFiled: July 14, 2020Date of Patent: November 23, 2021Assignee: ROSEMOUNT AEROSPACE INC.Inventor: Mark Ray
