Abstract: Embodiments relate to adjusting an image frame based on motion sensor data. An image frame including image data for a plurality of rows of the image frame is captured sequentially row-by-row. Motion sensor data corresponding to the image frame is also captured. Motion vectors describing motion between each row of the image frame are determined based on the motion sensor data. An image data translation is calculated for each row of image frame based on the motion vector for the row. The image frame is adjusted based on the image data translation for each row of the image frame to generate an adjusted image frame.

Abstract: A head-mounted display (HMD) device includes a plurality of activity detection sensors coupled to a liner formed around a periphery of a HMD or a band attached to the HMD. The sensors attached to the liner are adopted for direct or indirect contact to an upper portion of a user's face, and the sensors coupled to the band are adopted for direct or indirect contact with a back side of the user's head. The activity detection sensors detect electrical field signals caused by muscle contractions in an upper portion of a user's face or brain activity signals when the user is wearing the HMD. The HMD includes a module that reconstructs and projects a facial animation model of the user and a cognitive state of the user based on signals from the activity detection sensors while the HMD is in use by the user.

A stand pole is fixedly coupled to the pivot joint fitting and extends away from the camera head.

Abstract: A detachable audio system with an interface plate mounted on a head strap, and a mounting plate assembly removably attachable to the interface plate with a portion of the strap between the plates to provide independent electrical and mechanical connections between the plates. The mounting plate assembly connects to an earbud assembly via a flexible audio cable. The mounting plate assembly has a threaded attachment member that mates with a threaded attachment member on the interface plate. A pair of electrical connectors on opposing sides of the threaded attachment member protrude from spaced apart cylindrical bosses, such that when the mounting plate is attached to the interlace plate, independent mechanical and electrical connections are provided for detachable retention and operation of the earbud assembly.

Abstract: A dual arm barrier assembly comprising spaced-apart stanchions and a pair of barrier arms pivotally connected to a first stanchion for movement between closed and open positions. The barrier arms have distal end portions immediately adjacent to and out of engagement with the second stanchion when in the closed position during normal operation and when the vehicle is out of engagement with the barrier arms. The first barrier arm in the closed position is at a height corresponding to vehicle's windshield, and the second barrier arm in the closed position is below the first barrier arm and is at a height corresponding approximately to the vehicle's body or frame. The second stanchion engages the barrier arms only when the vehicle presses against barrier arms, thereby securely retaining the barrier arms in the closed position.

Abstract: A deformation sensing fabric comprises a fabric substrate comprising a first fabric layer and a first conductive element woven into the first fabric layer. The first conductive element outputs a first instrumented signal, responsive to an applied stimulus signal, indicative of a measure of change in an electrical property of the first conductive element in response to a strain applied to the fabric substrate along a long-axis of the first conductive element. The first conductive element is instrumented by a measurement system which stimulates the first conductive element and measures an electrical property of the first conductive element.

Abstract: A ?LED device comprising: a substrate and an epitaxial layer grown on the substrate and comprising a semiconductor material, wherein at least a portion of the substrate and the epitaxial layer define a mesa; an active layer within the mesa and configured, on application of an electrical current, to generate light for emission through a light emitting surface of the substrate opposite the mesa, wherein the crystal lattice structure of the substrate and the epitaxial layer is arranged such that a c-plane of the crystal lattice structure is misaligned with respect to the light emitting surface.

Abstract: A handheld controller, comprising a main body, handle extending from the main body, first and second input controls positioned for engagement by a user's fingers, and a finger detection sensor coupled to the first input control. One or more finger detection sensors are configured to detect the spatial location of the user's finger relative to a surface of the first input control. The finger detection sensor can be a touch capacitive sensor. The handheld controller can have one or more proximity sensors configured to detect the spatial location of the user's finger relative to the first input control.

Abstract: A virtual reality (VR) headset calibration system calibrates a VR headset, which includes a plurality of locators and an inertial measurement unit (IMU) generating output signals indicative of motion of the VR headset. The system comprises a calibration controller configured to receive a headset model of the VR headset that identifies expected positions of each of the locators. The controller controls cameras to capture images of the VR headset while the headset is moved along a predetermined path. The images detect actual positions of the locators during the movement along the predetermined path. Calibration parameters for the locators are generated based on differences between the actual positions and the expected positions. Calibration parameters for the IMU are generated based on the calibration parameters for the locators and differences between expected and actual signals output by the IMU. The calibration parameters are stored to the VR headset.

The device includes a body and a receptacle formed in the body, the receptacle configured to receive the anchor member therein. A housing can removably cover the receptacle to secure the anchor member in place, and a notch in the housing receives a portion of the lanyard therethrough.

Abstract: A system calibrates one or more head-related transfer functions (HRTFs) for a user. An indicator is presented on a head-mounted display, where the indicator prompts the user to turn the user's head to view the indicator and effectively change the user's head orientation. The head orientation corresponds to positions of both ears, thus a position of the indicator prompting to change the user's head orientation is associated with corresponding positions of both ears. Responsive to the indicator being viewed by the user, a sound source at a fixed position transmits a test sound and the test sound is received at microphones coupled to the user's ears. By analyzing the test sound received at the microphones, a unique HRTF associated with a relative position between the sound source and each ear can be obtained.
