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.

An automated computing system and method for determining fingering of musical instruments from digitized scored music or tablature. The computerized automated finger finder system and method analyzes a musical composition and determines hand and / or fingering positional information such that the musical composition can be efficiently played on a musical instrument of choice with minimal hand movement. The method and computing system also provide alternate or secondary fingering choices such that the musician can play with a different tonal stylization or with greater or lesser ease depending on his skill level.

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.

An escape system for moving a person on a cord on the exterior of a building. The building has a first surface and a second surface. The first surface and the second surface are substantially perpendicular to each other. The system comprises a control device for controlling the movement of the person on the cord and an anchoring device for reversibly mechanically attaching the control device to the building. The control device is substantially irreversibly mechanically connected to the anchoring device. The anchoring device has a first elongated element and a second elongated element. The first elongated is mechanically connected to the second elongated element. The first elongated element and the second elongated element are configured such that, the first elongated element at least partially rests against the first surface of the building and the second elongated element at least partially rests against the second surface of the building.
