Abstract: A tool cabinet includes a cabinet body having two guide rails, a movable working platform unit having two extension members that are respectively coupled to the guide rails, two lifting units, and a driving unit. Each extension member has an inner coupling hole. Each lifting unit has a support member, a threaded rod, and a threaded member movably and threadedly engaging the threaded rod. Rotation of the threaded rods results in the movement of the working platform unit between lowered and lifted positions. When the working platform unit is arrested in the middle of being driven from the lifted position to the lowered position while the driving unit continues to operate, the rotation of the threaded rod drives the threaded member to slide away from the support member.

Abstract: A system and method are provided that enhances a user's experience when using a see-through near eye display device. A user interface is provided for a user to manage single or simultaneous applications in a head mounted device. Applications for the head mounted device may be activated or deactivated by the user via the user-interface. The user's total field of view (TFOV) which accounts for a complete range of rotation and translation of the user's head may be determined by tracking the user's head position and rotation relative to the user's body and an environment associated with the user. One region of the user's TFOV (e.g., the right-hand side) may display an “application menu” including a list of applications that can be launched, and another region of the user's TFOV (e.g., the left-hand side) may display an “active menu” including a list of applications currently running.

Abstract: Systems, methods, and computer media for calibrating user-mounted devices are provided. An external device capable of providing calibration data to a user-mounted device worn by a user is identified. An identification acknowledgement is received from the external device. A device calibration mode is entered in which calibration data describing the user-mounted device is received by the user-mounted device. The calibration data is based at least in part on sensor data acquired and normalized by the external device. The calibration data is then received. The calibration data includes at least one determined pose or body measurement of the user and a calculated alignment of the user-mounted device relative to the user. The user-mounted device is calibrated using the received calibration data.
