  • Publication number: 20250181173
    Abstract: Aspects of the present disclosure can trigger an action based on a motion detected by an artificial reality (XR) device, such as a head-mounted display (HMD). The XR device can display an XR experience to a user. While displaying the XR experience, the XR device can detect a physical interaction with the XR device using one of more sensors (e.g., sensors of an inertial measurement unit (IMU)). The physical interaction can generate a movement profile captured by the one or more sensors. The XR device can identify the physical interaction as a particular motion (e.g., one or more taps on the XR device) by applying a machine learning model to the movement profile. In response to identifying the particular motion, the XR device can trigger an action on the XR device (e.g., activating pass-through on the XR device).

  • Publication number: 20250104365
    Abstract: For artificial reality (XR) applications that need a guardian, aspects of the present disclosure can automatically determine where boundaries should be set in the real-world environment. Using a machine learning model, the automatic boundary system can detect the floor plane, then generate a height map of the real-world environment with the floor at zero. The height map can include positive heights (e.g., objects on the floor) and negative heights (e.g., downward leading stairs). The automatic boundary system can then generate a boundary for the area based on the detected heights by: applying thresholds to disregard objects at certain heights, applying thresholds to disregard open areas at certain widths, excluding oddly shaped areas that would constantly trigger the boundary if the user were nearby, etc. The user can further manually adjust the generated boundary in both directions (e.g., bringing it closer or further from the user).

  • Publication number: 20250104366
    Abstract: Instead of having a constant boundary, artificial reality (XR) applications that can run in boundaryless mode (e.g., in augmented or mixed reality) can be given controls by selective boundary system on an XR system to customize partial boundaries. For example, an application can specify to select particular boundaries when certain object types are in the real-world environment. In another example, an application can transition to different boundary modes when certain application events occur (e.g., when transitioning from virtual reality to mixed reality). On the backend, the selective boundary system can provide the application with an API that exposes boundary information. Based on this information, the application can use the API to create new boundaries or turn on or off certain boundaries based on requests by the application.

  • Publication number: 20250069334
    Abstract: Aspects of the present disclosure are directed to providing assisted scene capture for an artificial reality (XR) environment. Some implementations can obtain an XR space model corresponding to a real-world space, including walls, the ceiling, and the floor, using an XR system. Some implementations can then scan the real-world space and display a mesh corresponding to the scanned area overlaid onto a view of the real-world space. Some implementations can perform post-processing on the displayed mesh, which can include A) collapsing variations in the mesh corresponding to the walls, ceiling, or floor onto the XR space model; B) clipping the mesh to the XR space model for open doorways, windows, etc.; C) simplifying the mesh corresponding to the walls, ceiling, or floor; D) determining that the mesh is complete by identifying that a threshold percentage of the XR space model is covered by the mesh; or any combination thereof.

  • Publication number: 20170323163
    Abstract: A method is disclosed for interrogating enclosed spaces such as sewers and the like by commanding a camera to travel through the enclosed space while transmitting the video feed from the camera to a remote location for viewing and processing. The processing involves image manipulation before analyzing frames of the video using a neural network developed for this task to identify defects from a library of known defects. Once a new defect is identified, it is inserted into the model to augment the library and improve the accuracy of the program. The operator can pause the process to annotate the images or override the model's determination of the defect for further enhancement of the methodology.

  • Patent number: 8769329
    Abstract: A peripheral power management system includes a power monitor for determining a power consumption characteristic of a computing processor and a controller for generating a reference power signal based on the power consumption characteristic. The peripheral power management system also includes a power regulator control signal generator for generating a power regulator control signal based on the reference power signal. The power regulator control signal controls a peripheral device power regulator which regulates an electrical supply power of a peripheral device. In this way, the peripheral power management system controls regulation of the electrical supply power of the peripheral device based on the power consumption characteristic of the computing processor. In some embodiments, the peripheral power management system determines the power consumption characteristic of the computing processor by monitoring communication on a serial voltage identification bus.

  • Patent number: 7815369
    Abstract: A method of measuring temperature of a TMR element includes a step of obtaining in advance a temperature coefficient of element resistance of a discrete TMR element that is not mounted on an apparatus, by measuring temperature versus element resistance value characteristic of the discrete TMR element in a state that a breakdown voltage is intentionally applied to the discrete TMR element and a tunnel barrier layer of the discrete TMR element is brought into a stable conductive state, a step of bringing a tunnel barrier layer of a TMR element actually mounted on the apparatus into a stable conductive state by intentionally applying the breakdown voltage to the mounted TMR element having the same structure as that of the discrete TMR element whose temperature coefficient has been measured, a step of measuring an element resistance value of the mounted TMR element with the tunnel barrier layer that has been brought into a stable conductive state, and a step of obtaining a temperature corresponding to the measure

  • Publication number: 20080100288
    Abstract: A seal inspector and a method of inspecting a seal are described. A seal inspector includes an eddy current sensor for detecting changes in an eddy current within a lid seal of a can. The eddy current sensor includes a signal line for creating a magnetic field, which induces the eddy current. The induced eddy current generates a magnetic field that acts on the alternating current and as a consequence produces an eddy current response. A signal processing control unit receives the eddy current response and determines whether a value associated with the eddy current has surpassed a threshold value. If the associated value has surpassed the threshold value, the can may be ejected from a can conveyor system.

A plurality of program lines within a first region are cladded with a flux-concentrating layer configured to focus a generated magnetic field while the portions of the program lines within a second region are uncladded so that the generated magnetic field is unfocused. Generally, the first region is associated with the operational MRAM elements and the second region is associated with the reference cell.

  • Publication number: 20060198057
    Abstract: A slider mounted CPP GMR or TMR read head sensor is protected from electrostatic discharge (ESD) damage and from noise and cross-talk from an adjacent write head by means of a balanced resistive/capacitative shunt. The shunt includes highly resistive interconnections between upper and lower shields of the read head and a grounded slider substrate and a low resistance interconnection between the lower pole piece of the write head and the substrate. The capacitances between the pole piece and the upper shield, the upper shield and the lower shield and the lower shield and the substrate are made equal by either forming the shields and pole piece with equal surface areas and separating them with dielectrics of equal thicknesses, or by keeping the ratio of area to insulator thicknesses equal.
