A head mounted display device has a mount which attaches the device to a user's head, a beam-splitter attached to the mount with movement devices, an image projector which projects images onto the beam-splitter, an eye-tracker which tracks a user's eye's gaze, and one or more processors. The device uses the eye tracker and movement devices, along with an optional head-tracker, to move the beam-splitter about the center of the eye's rotation, keeping the beam-splitter in the eye's direct line-of-sight. The user simultaneously views the image and the environment behind the image. A second beam-splitter, eye-tracker, and projector can be used on the user's other eye to create a stereoptic, virtual environment. The display can correspond to the resolving power of the human eye. The invention presets a high-resolution image wherever the user looks.

A hybrid air and liquid coolant conditioning unit is provided for facilitating cooling of electronics rack(s) of a data center. The unit includes a first heat exchange assembly, including a liquid-to-liquid heat exchanger, a system coolant loop and a facility coolant loop, and a second heat exchange assembly, including an air-to-liquid heat exchanger, an air-moving device, and the facility coolant loop. The system coolant loop provides cooled system coolant to the electronics rack(s), and expels heat in the liquid-to-liquid heat exchanger from the electronics rack(s) to the facility coolant. The air-to-liquid heat exchanger extracts heat from the air of the data center and expels the heat to the facility coolant of the facility coolant loop. The facility coolant loop provides chilled facility coolant in parallel to the liquid-to-liquid heat exchanger and the air-to-liquid heat exchanger. In one implementation, the hybrid coolant conditioning unit includes a vapor-compression heat exchange assembly.

An apparatus for removing formation sand from an oil storage tank. The apparatus is mounted to a truck towable trailer so that it may be transported to remote sites. Mounted to the truck towable trailer is a container adapted to accept and dewater a sand-water slurry pumped from the oil storage tank. The slurry is formed by injecting high pressure water from a water reservoir mounted to the truck towable trailer into the approximate centre of mass of the formation sand by way of a pipe having a nozzle generating a spherical spray pattern within the slurry. The pipe is forced into the slurry by way of a two counter-rotating drive wheels in frictional contact with the pipe. Included in the apparatus is a bifurcated conduit adapted for attachment to the storage tank drain port adapted for the injection of high pressure through one branch of the conduit and withdrawal of slurry from the other branch and into the container by way of a slurry pump. The dewatering of the slurry takes place by a plurality of screen filters mounted to the bottom, side and front inside walls of the container. Oil and water extracted from the slurry is recycled back into the storage tank for later removal and treatment. All pumps and conduits are mounted to the truck towable trailer so that the apparatus is self-contained.

A MEMS scanning device includes more than one type of actuation. In one approach capacitive and magnetic drives combine to move a portion of the device along a common path. In one such structure, the capacitive drive comes from interleaved combs. In another approach, a comb drive combines with a pair of planar electrodes to produce rotation of a central body relative to a substrate. In an optical scanning application, the central body is a mirror. In a biaxial structure, a gimbal ring carries the central body. The gimbal ring may be driven by more than one type of actuation to produce motion about an axis orthogonal to that of the central body. In another aspect, a MEMS scanning device is constructed with a reduced footprint.

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 non-invasive vagal stimulation device and method. The device comprises a body having a vibration member. The stimulation is created by the vibration member which has a vibratory rate that can be adjusted from being off to a preferred operating range. The non-invasive stimulation method consists of placing the non-invasive stimulation device in the vicinity of the carotid artery bifrication where arises a carotid sinus and body which contain afferent sensory nerves that travel to medulla oblongata of brain, and either applying pressure in place, or moving the device along the target arm. The method can be accomplished either with the vibration feature of the device turned on or off.

A mobile apparatus and method of timing synchronization. The mobile apparatus comprises a timing synchronization controller, a frame detector, a decoder, and a clock generator. The timing synchronization controller determines a number of times of the mobile station clock switching from a first clock speed to a second clock speed, and compares the number of times of the mobile station clock switching the clock speed with a predetermined number of clock speed switch. The frame detector, coupled to the timing synchronization controller, receives a control channel block when the number of times of clock speed switch reaches the predetermined number of clock speed switch. The decoder, coupled to the frame detector, decodes the control channel block to compute a timing error between the base station clock and the mobile station clock. The clock generator, coupled to the decoder, receives the timing error to compensate for the mobile station clock.

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.

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.
