The present invention relates to artificial limbs generally and joints for same. The present invention provides hydraulic functional units whereby enabling movement of artificial joints to closely correspond with natural human movement. In the provision of realistic joints, as used in prosthetic limbs, an important aspect in achieving realistic movement is providing a different operating characteristic to the joint when under load. One important characteristic of an artificial leg for achieving a natural-looking walking gait corresponding with those of a stabilized knee, i.e. a knee resisting flexion when under load, is when it bears at least some of the weight of the amputee. Properties of resilient mechanical members are utilized to enable a hydro-mechanical system to be controlled so that it releases a low joint resistance mode relative to a default high resistance mode. The invention also permits alternative embodiments such as electronic, electro fluidic or electromechanical means.

The present invention relates to artificial limbs generally and to joints for the same. In particular, the present invention provides hydraulic functional units (35), generally classified as damping devices as connected between artificial limbs whereby to enable movement of artificial joints to closely correspond with natural human movement. In the provision of realistic joints, as used in prosthetic limbs, an important aspect in attempting to achieve a realistic movement is to provide a different operating characteristic to the joint when under load. Indeed, one of the more important characteristics of an artificial leg for achieving a natural-looking walking gait correspond with those of a so called stabilized knee, i.e. a knee which resists flexion when under load, that is when it is bearing at least some of the weight of the amputee. In accordance with the invention, there is provided hydraulic damper control elements for prostheses which utilize a pressure differential due to the presence a fluid flow as a direct control input for a at least one hydraulic valve (47). The valve can comprise a vortex flow arrangement (47f) to cause fluid flow to circulate about aperture. The valve can comprise a moveable element which abuts a resiliently mounted element which reduces the size of an aperture as the force increases.

A sealing device for a medical instrument includes a fastening area and a sealing area designed to either bear on the circumference of a medical instrument inserted into the sealing device or to close the sealing device when no medical instrument is inserted. The sealing device further includes a first elastic wall enclosing the sealing area in a ring shape, with an annular first edge, which is connected to the sealing area, and an annular second edge, and a second elastic wall which encloses the first wall in a ring shape and is spaced apart there from, with an annular first edge and an annular second edge, which is connected to the fastening area.

A method of and system for terminating or assigning outstanding OTC derivative transactions between a plurality of financial institutions (banks). The system comprises: a processing station arranged to receive transaction data describing a plurality of transactions from a plurality of banks via the Internet. The processing station comprises: a linking module for linking different versions of the same transaction received from different parties to that transaction; an analysis module for determining a set of linked transactions between a plurality of different banks, wherein each bank has debts and claims towards other banks in the set; a calculation module arranged to calculate an aggregated value of each set of linked transactions and select the set of linked transactions which has an aggregated value within bank-specified tolerance limits acceptable for executing a termination; and an execution module for executing a termination or assignment of the selected set of linked transactions.

A machine tool is provided, in particular for the synchronous machining of workpieces. The tool includes two or more spindle units (2, 3), which run parallel in a machining unit and are designed to hold tools and repositioning devices for the precise adjustment of the position of the spindle units (2, 3) in relation to one another, preferably in all three directions x, y and z of the orthogonal co-ordinate system in the machining unit (4). The repositioning devices for displacing at least one of the spindle units (2, 3), at least in an x and / or y direction, include an eccentric bush (5, 6), which can be rotated about a central shaft (B1, B2) and locked and in which the spindle units (2, 3) are mounted eccentrically, parallel to the central shaft (B1, B2).

Non-contact position and motion sensing is improved for oscillator frequency based sensors in response to adding a two phase calibration along with bootstrapping circuit. Calibration is performed across the multiple sensor channels, so that: (1) maximum sensor channel loading is determined, and (2) the amount of capacitive load required for each other channel to match this same maximum load is stored for application to that channel during non-contact sensing. Capacitive coupling between channels is nullified by a bootstrapping process, in which time-domain voltage on the active channel is replicated on the non-active channels during non-contact sensing, thus creating equal potentials across inter-channel couplings that effectively eliminate inter-channel capacitive loading.

A foot operable percussion instrument producing jingling sounds similar to a tambourine is useable by a solo performer and possesses a wedge-shaped body with an inclined striking surface for the striking by a foot or a portion thereof. The wedge-shaped body is connected to a base plate member by a pair of rigid connectors that together define a fulcrum so that the front portion of the wedge-shaped block pivots downwardly when struck by a foot on the inclined striking surface and rights itself when the foot is lifted. The jingling sound produced is of short duration.
