    Abstract: A measurement system is described herein that accurately calculates the complete position and orientation of a dynamic object in real-time. The measurement system includes a laser unit, a target, a camera unit, and a control unit. The target is arranged to rotate about all three spatial axes, and includes a reflective element, a gyroscope, and a pair of light emitting devices. The laser unit is arranged to rotate about two of its spatial axes, and further arranged to emit a laser beam toward the target. The reflective element reflects the laser beam back toward the laser unit, where the laser unit detects the returned laser beam. The camera unit is arranged to detect light emitted from the pair of light emitting devices. The control unit is arranged to gather information and data captured by the system to determine the position and orientation of the object.

  • Patent number: 9942466
    Abstract: A convertible computer includes a transparent optical element in the keyboard base that provides light pass-through for the camera but does not interfere with the user's experience. The transparent optical element may include a transparent glass or plastic element that maintains the imaging specifications of the rear-facing camera. In some implementations, the transparent optical element can maintain the f-number of the optical system that includes the camera and the transparent optical element and may not affect image quality of images captured by the camera. In some arrangements, the transparent optical element can include an optical system that can increase the light-gathering ability of the camera (e.g., decreases f-number), effectively converting the camera lens into a macro lens. In other arrangements, the transparent optical element can include an optical system that can improve the imaging of distant objects (e.g., increases f-number), effectively converting the camera lens into a telephoto lens.

  • Patent number: 9921853
    Abstract: Various features for a computer operating system include mechanisms for operating where a single native application, in the form of a Web browser, exists for an operating system, and all other applications run as Web apps of the browser application. A computer-implemented object tracking method includes instantiating, a first time, an operating system object on a computing device; automatically identifying contextual meta data that defines a state of objects that are open on the computing device, other than the instantiated operating system object, when the operating system object is instantiated; and storing the identifying contextual meta data in correlation with the operating system object, wherein the contextual meta data identifies one or more objects that are active in the operating system when the operating system object is instantiated.

  • Patent number: 9882895
    Abstract: A first computing device provides an indication that the first computing device accepts dynamic user registration of user accounts over a wireless connection. A second computing device automatically connects to the first computing device and passes an account token to the first computing device over the wireless connection, all without physical interaction with the first computing device. The first computing device automatically contacts a remote account server to retrieve a user account associated with the account token and registers the user account with the first computing device.

  • Patent number: 9785195
    Abstract: A portable computing device may include a lid and a base. The lid may include a display on a front side of the lid. The base may be rotatably attached to the lid. The rotatable attachment of the base to the lid may enable the lid to rotate from an open position in which the lid is rotated away from the base to a tablet position in which a back side of the lid faces a bottom side of the base. The base may include a keyboard on a top side of the base and an elastic sheet extending over the keyboard. The keyboard may include keys configured to retract into the base in response to the lid rotating to the tablet position and extend out of the base in response to the lid rotating out of the tablet position.
