The present invention relates to artificial limbs generally and to joints for the same. In particular, the present invention provides hydraulic functional units, 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 stabilised 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. The valve can comprise a moveable element which abuts a resiliently mounted element which reduces the size of an aperture as the force increases. Further, a moveable body acts upon the valve to enable an increase or decrease of flow of hydraulic fluid through the valve, whereby to enable an increase in gait by way of reduction of resistance to flow or to reduce or stop flow by way of a stumble recovery mechanism.

Apparatus and methods automate selection of patient interface(s) according to their size, such as with processing in a processor(s) or in a server(s). Image data captured by an image sensor may be received. The captured image data may contain facial feature(s) of an intended user of the patient interface. The facial features may be captured in association with a predetermined reference feature of known dimension(s). The user's facial feature(s) and the reference feature may be detected in the captured image data. Image pixel data of the image may be processed to measure an aspect of the detected facial feature(s) based on the reference feature. A patient interface size may be detected from standard patient interface sizes based on a comparison between the measured aspect of the facial feature(s) and a data record relating sizing information of the standard patient interface sizes and the measured aspect of the facial feature(s).

A transaction processor can receive transaction information from a transaction between a customer and a merchant. The transaction information includes an account identifier associated with a financial account of the customer. The processor determines that the account identifier is associated with a fixed price futures contract. The transaction is completed at the current market price. Thereinafter, the processor can determine if the fixed price is lower than the current market price. If the fixed price is lower than the current market price, the process determines the difference in cost for the transaction if the fixed price were used. Then, the processor can create and send a resettlement transaction to the customer's account to reimburse the customer for the difference. As such, the customer receives a simple method for paying for commodities at a set price without having special payment instruments or special accounts.
