A hinge used for a mobile device includes a base mounted on a body of the mobile device. A bracket is rotatably mounted on the base by an upright pintle. A positioning washer is provided between the bracket and the base. A seat is mounted on the bracket, and a lateral pintle is rotatably installed on the seat and substantially perpendicular to the upright pintle. A monitor of the mobile device is installed on the lateral pintle. Whereby, the monitor can be raised while the lateral pintle is rotated about the seat, and can be turned left or right for adjusting a horizontal visual angle while the bracket is rotated about the upright pintle.

A lighting device includes a reflector that has forward and rearward segments separated by a clearance for cooling, a gobo holder into which gobos of differing sizes can be inserted and held in position, and a lens holder which can be moved forwardly and rearwardly in the lighting device by rotation of a gear which is attached to the lens holder and engages a rack in a slide guide in the lighting device, the gear being moved by a knob located outside the lighting device and which is rotatable with the gear and movable along the lighting device.

Robots and other mobile apparatus, especially robotic bipeds, that exhibit agile capabilities can become easily destabilized by obstacles or particular surfaces. An algorithm for controlling the movement of a robot based on visual cues and learning processes will help to avoid destabilization and movement interruption by altering the gait measurement. As such, when the robot predicts that an obstacle is upcoming, it can make adjustments by either increasing or decreasing stride so that a smooth transition can be made in bypassing the obstacle.

A mobility device to provide ambulatory support includes a tubular body having upper and lower parts. The upper part has at least four, and preferably five, bends and includes a manually graspable handle portion between two of the bends, and a hook-shaped bend for engaging the user's forearm on three sides adjacent the elbow. An intermediate portion including another bend is positioned between two other bends, and is positioned between the handle portion and the bend located adjacent the user's elbow. The lower part includes a floor-engaging free end and defines an axis, preferably a generally vertical axis. The bends and other features of the upper part cooperate to provide improved support for a user's forearm. Also disclosed is a rocker-type end member either fixedly or slidably fitted to the lower part.

An assistive mobility device is provided that includes an automatic positive locking system, which permits an operator to move the assistive mobility device when an actuator is engaged and automatically lock the assistive mobility device when the actuator is disengaged. The assistive mobility device includes a braking system, stowable footrest and armrests, and an adjustable back, which all require the single-handed operation of the operator to function. The collapsible footrest is stowed under the seat permitting an occupant optimal entry into or exit from the assistive mobility device. The assistive mobility device can be formed from non-corrosive materials, including stainless steel, composite fibers, nylon, and plastics, for use in aquatic environments.

A movable belt conveyor system for a leach pad for use for sulfidic copper ore, where favorable conditions are to be generated for leaching out the copper by a slight compaction of the ore piled up into a dump for the microbiological leaching technology. The movable belt conveyor system of a length of up to several km is composed of a plurality of smaller belt segments, comprising a tail segment (70), standard segments (711-n) and a head segment (72), as well as a traveling tripper (8). To prevent the loading by these individual components from being excessively compacted by the weight of the device during multiple travel over the dump during the moving process, the belt drives with the driving drum are accommodated in the tail element (70), which is supported on the soil next to the leach pad. In addition, the traveling tripper (8) is designed as an independent unit with the belt drums, additional belt drives and the belt-tensioning means, which unit is autarchically displaceable on a caterpillar-type moving gear (85) of its own. Due to the moving of the belt on the caterpillar-type moving gears of the standard segments (711-n), on the head segment (72) and on the traveling tripper (8) as well as due to the absorption of the weight of the tail segment (70) by the transfer carriage (6), the surface pressure acting locally on the dump is reduced and the compaction of the ore on the dump due to being traveled over by the belt conveyor system remains low. Traveling over with a moving device, which frequently happens with the use of a moving caterpillar, is eliminated.
