The present invention provides a method, system and apparatus for a time stamped visual motion sensor that provides a compact pixel size, higher speed motion detection and accuracy in velocity computation, high resolution, low power integration and reduces the data transfer and computation load of the following digital processor. The present invention provides a visual motion sensor cell that includes a photosensor, an edge detector connected to the photosensor and a time stamp component connected to the edge detector. The edge detector receives inputs from the photosensor and generates a pulse when a moving edge is detected. The time stamp component tracks a time signal and samples a time voltage when the moving edge is detected. The sampled time voltage can be stored until the sampled time voltage is read. In addition, the edge detector can be connected to one or more neighboring photosensors to improve sensitivity and robustness.

The embodiment herein generally relates to a system to apply moments to a user, particularly during gait. The system is a portable gyroscopic-assisted system, mounted on a user's body, particularly the upper body, particularly to influence orientation of users having difficulty with balancing during gait. The system comprises a plurality of variable-speed control moment gyroscopes (VSCMGs). The VSCMGs generate moments, particularly to counteract a fall to any direction. The VSCMGs are placed close to the center of mass of the user. The couple moments of the VSCMGs are transmitted to the user through a support structure that is tightly attached to the user. Particularly, the system controls moments based on detecting pre-fall conditions.

Micro-regional force application improves the control of the orthodontic movement of teeth in all six degrees of freedom. Micro regional force application utilizes an elastic repositioning appliance, a tooth positioner, a polymeric shell, or preprogrammed series of polymeric shells. The key components of the invention are the envelope of freedom, the force applicators, force couplers, counterpart coupling, vector modifiers, seating guides, decouplers, and forced balance points. Further, computerized finite element analysis determines the center of resistance and the center of rotation for each tooth to be moved. The present invention gently rotates and translates one or more teeth to a desired straight position within a treatment plan.

A pull-type crop harvesting machine has a header carried on a frame mounted on ground wheels with a hitch arm extending from the frame over the header to a hitch coupling of a tractor. The hitch arm is mounted for pivotal movement about a generally upright axis such that in a first position the tractor tows the frame in echelon to one side and in a second position the tractor tows the frame in echelon. The movement is actuated by a hydraulic cylinder and stopped at one end of the movement by the piston with a rod coupling being adjustably mounted on the rod to adjust the end position. At the other end of the movement, the position is defined by a stop member mounted on the piston rod and adjustable relative thereto. Each end of the cylinder includes a cushion effect by using separate orifices for the fluid ports which slow fluid flow as the piston approaches the ends of the cylinder.

Two embodiments of a guard are provided for protecting a padlock securing stanchion levers in their door locking position. An opening in the front wall of the guard permits its use with padlocks having long shackles as well as those with regular length shackles while retaining the compactness not normally retained for the extended length of the shackles. The preferred construction lock guard has a pitched roof and a pair of legs on its laterally outer sides extending downwardly behind the stanchion lever at laterally opposite sides of the stanchion latching mechanism that increase stability, rigidity of the housing and protection of the latches.

A common rail directly actuated fuel injection valve is disclosed with a hydraulic transmission device that is fluidly isolated from the fuel so that the hydraulic fluid can be different from the fuel. This arrangement is particularly suitable for valves that inject a gaseous fuel, but can also be beneficial for use with liquid fuels. According to the method, the hydraulic fluid is pressurizable by the fuel pressure to reduce differential pressures and leakage, in addition to assisting with operation of the hydraulic transmission device. The method further comprises detecting the position of the valve needle for more accurate control of rate of fuel injection during an injection event.

Control system for a remote-controlled working machine (10) provided with caterpillar tracks (6) or the like for the travel thereof, e.g. a demolition robot intended for demolition work, etc., the said control system including a remote control (11) intended to be carried by an operator situated beside the machine (10), the said remote control (11) being connected wirelessly, e.g. via Bluetooth, or by means of a cable to at least one electronic unit in the machine, and having at least one control stick or joystick (12, 13) and a number of buttons, levers and / or knobs for operating the different travel and working functions of the machine. The machine furthermore has one or more different setting modes or positions, wherein its control sticks and / or certain buttons have different functions in different modes. In a travel mode, also referred to as a transport position, travel of the machine is handled entirely by one control stick (12, 13), advantageously the left control stick (12), such that the caterpillar tracks (6) of the machine are operated as follows: - if the control stick is moved forwards or backwards, both caterpillar tracks (6) are driven forwards or backwards so that the machine moves forwards or backwards; - if the control stick is moved straight to the left, the right caterpillar track is driven forwards and the left caterpillar track is driven backwards so that the machine turns to the left; - if the control stick is moved straight to the right, the left caterpillar track (6) is driven forwards and the right caterpillar track is driven backwards so that the machine turns to the right. The operator's other hand is thus free for other tasks during travel of the machine.

A pulling tool includes a housing and a tube disposed within the housing, the tube configured to supply hydraulic fluid. The spike puller further includes a piston rod connected to a piston. The piston rod has a hollow axial bore, and the piston and the piston rod are axially moveable relative to the tube. The spike puller has a passage communicating fluid from the tube to the piston. The passage is contained within the housing. The passage is variable between a first configuration in which hydraulic fluid flows at a first restricted flow so as to provide a slower retraction of the piston rod and a second configuration in which hydraulic fluid flows at a second less restricted flow so as to provide a faster retraction of the piston rod.

The invention discloses a balance valve. In the balance valve, a main valve core and a control piston are placed in two cavities of a valve body respectively; a control valve core is arranged in a cavity of the main valve core in an embedded mode; when working pressure oil liquid enters the valve body from a second oil opening, the control piston moves to the right to pull the control valve core to move to the right, a second segment of the control valve core is separated from a ring-shaped protrusion of the cavity of the main valve core; the working pressure oil liquid acts on the protruding surface of the outer edge of the main valve core, the main valve core moves to the right, namely the transitional surface of the main valve core is separated from the transitional surface of a second cavity, and the working pressure oil liquid passes the second cavity of the valve body and flows out of the valve body by a first oil opening; because the control valve core needs to be opened before the main valve core is opened and in fine adjustment, the main valve core is still at a closing state and relatively smoothly moves, so that the vibration caused by loading operation is eliminated; and when the control pressure continuously increases, the main valve core moves to the right under an action of the working pressure of the second oil opening, the opening is free from the influence of control pressure, a heavy article can smoothly fall at a controlled speed, and the control accuracy is improved.
