  • Patent number: 9618749
    Abstract: Technologies for mitigating a physiological condition include a wearable computing device coupled with a head-mounted display and sensor(s). The wearable computing device may receive sensor data indicative of a physical attribute of the user while displaying information on the head-mounted display. The wearable computing device analyzes the sensor data to detect a physiological condition of the user and, if detected, applies a mitigation strategy to mitigate the physiological condition. The detected physical condition may be a nausea condition or a seizure condition. To reduce potential risk to the user, the wearable computing device may buffer information to be displayed by the head-mounted display, analyze the display information based on risk factor rules to determine whether the display information presents a potential risk to the user, and reduce the display rate of the head-mounted display in response to the potential risk to the user.

  • Patent number: 9618769
    Abstract: A long-range optical device has at least one optical channel, which has a housing and an arrangement of optical elements, wherein at least one of the optical elements is movable relative to the housing for image stabilization in the event of perturbing movements of the housing. The device further has a first passive stabilization system based on mass inertia for the at least one movable optical element, which, in the event of displacement of the at least one optical element relative to the housing, generates a first restoring force proportional to the displacement and a second restoring force proportional to the displacement velocity. The first stabilization system is designed for image stabilization in the event of perturbing movements in a first frequency range.

  • Patent number: 9618770
    Abstract: There is provided a camera module including a plurality of ball bearings to support the driving of a lens barrel at the time of compensating for unintended camera movement due to disturbance such as hand shake. The lens barrel may be driven in first and second directions, independently, by one driving force exerted in the first direction perpendicular to an optical axis and by another driving force exerted in the second direction perpendicular to both the optical axis and the first direction, thereby preventing driving displacement from being generated at the time of compensating for unwanted motion such as hand shake while securing reliability against external impact, and having reduced power consumption at the time of compensating for the disturbance.

  • Patent number: 9618783
    Abstract: An improved Liquid Crystal Display (LCD) heating system is provided. Resistor meshes, in particular VCOM resistor heating meshes, in the pixel array improve capacity of the display heater (heating system) so that the display is heated faster from low temperatures. The resistor mesh design provides much lower resistance from one point in the pixel array to an edge than pixel-to-pixel horizontal VCOM resistance, thus reducing horizontal crosstalk. Further, the approach permits the display to be active during the warm-up process.
