A flooring system for use with floating floors is described which includes a glider bar having base portions including extending rails in the form of dovetail protrusions. The bases and rails are longitudinally moveable relative to anchoring plates, which anchoring plates are affixed to a subflooring. Flush finished floor moldings are slid longitudinally along the rails and are glued or mechanically fixed, at one side only, to the adjacent floating laminate flooring. By this assembly, smooth transitions between adjacent floating floors, or where floating floors meet another hard floor covering, or carpet, can be achieved. The system can also be used with flush stair nosing elements.

The present invention relates to a horn antenna device. The horn antenna device has a step-shaped signal feed-in apparatus and a conical horn antenna. The step-shaped signal feed-in apparatus has a stepped body having multiple stairs and a connecting pin. The stepped body is adapted to radiate electromagnetic waves and receive a reflection of the electromagnetic waves. According to the structure of the step-shaped signal feed-in apparatus of the invention, the resonating modes are easy to be determined. The directivity and the signal-to-noise rate are improved. In addition, the connecting pin is directly connected to the stairs for improving the signal stability of the horn antenna device.

The lower extremity exoskeleton comprises two leg supports connectable to person's lower limbs and configured to rest on the ground during their stance phase. Each leg support comprises a thigh link and a shank link; a knee joint configured to allow flexion and extension between the shank link and the thigh link. The lower extremity exoskeleton further comprises an exoskeleton trunk connectable to the person'supper body. The exoskeleton trunk is connectable to the thigh links of the leg supports allowing for the flexion and extension between the leg supports and the exoskeleton trunk. Two torque generators are coupled to each of the knee joints. A power unit, capable of providing power, is coupled to the torque generators. In operation when a leg support is in a stance phase and climbing a slope or stairs, the power unit injects power into the respective torque generator thereby extending the respective knee angle. When a leg support is in stance phase and not climbing a slope or stairs, the power unit does not inject any power to the respective torque generator, but without dissipating any stored power in said power unit, it forces the torque generator to resist flexion of the respective knee joint. When a leg support is in a swing phase, the power unit does not inject any power to the respective torque generator, but without dissipating any stored power in said power unit, it forces the torque generator to minimize its resistance to knee flexion and extension.

A system and method associated with the movement of a limb. In one example, the system, such as a prosthetic or orthotic system, includes an actuator that actively controls, or adjusts, the angle between a foot unit and a lower limb member. A processing module may control movement of the actuator based on data obtained from a sensor module. For instance, sensing module data may include information relating to the gait of a user and may be used to adjust the foot unit to substantially mimic the movement of a natural, healthy ankle. The system may further accommodate, for example, level ground walking, traveling up / down stairs, traveling up / down sloped surfaces, and various other user movements. In addition, the processing module may receive user input or display output signals through an external interface. For example, the processing module may receive a heel height input from the user.

An intraocular lens (IOL) inserter and method of use ensure that an artificial intraocular lens is controllably ejected from a cartridge and into a patient's eye by using successive, predefined detent positions. One embodiment has a distal pivotal portion that can be pivoted to a desired angle as a mover advances the IOL into the eye. A detent controls the motion of the mover. In one embodiment, the detent includes a longitudinally extending component with a plurality of stair steps, so that a face of each stair step engages the housing at each different predefined detent position. Other embodiments include at least one orifice in the housing, so that when the orifice is aligned with a pin or protrusion, it engages the orifice to define a detent step.

A system that includes a pop-up graphical user interface that includes menu bars overlapping marking menu zones. The interface pops up at the current position of the cursor when the space bar is held down. The menu bars are positioned around a central marking zone with the common menu bars located above the central zone and task specific menu bars located below the central zone. The common application menu bar is positioned outer most and the common window menu bar is located inner most. The menu bars are sized in a “stair-step” pattern and the commands therein are left and right justified to fill the menu bar evenly. The menu bar menu items are accessed just like menu bar items typically found at the top of windows. The menu bars mimic the menu bars that a user may need to use during tasks that users typically perform using the menu bars found in application windows. The zones are divided into a central zone and four outer zones where user customizable marking menus are activated when a mouse button is held down while the cursor is in one of the zones.

A system generates an estimated floor area measurement of a building based on the calculated estimated total roof area of the roof of the building. This is based on a correlation between the size of the building roof and the size of the building. Typically, the floor area of a single full floor of the building is roughly the size of the roof of the building if the roof were flat with no slope. This in effect is turning the roof into a floor to generate estimated floor area. With additional adjustments to area measurements to account for multiple floors, roof overhang, wall width, internal building features such as walls and staircases, and / or obstructed views of the building in the aerial image(s), etc., an even more accurate floor area estimation may be generated.

A microelectronic assembly incorporates units stacked one above the other and may include a plurality of similar stacks mounted to a circuit board. Some of the stacks may be inverted, rotated or both relative to other stacks so that corresponding edges of the stacks face one another to facilitate communication between the stacks. Communication between the stacks may be carried along traces on one or more interposers intercepting the stacks remote from the circuit board. Within each stack, conducting paths may extend in vertical columns or in other arrangements such as a stair step arrangement wherein each conductive path traverses a series of column positions, or in a crossing arrangement such two conductive paths cross back and forth between column positions along the vertical extend of the stack. A stack may include portions disposed above and below the circuit board.
