摘要： The method can determine physical properties of the ground stepped upon by a user wearing a footwear incorporating an accelerometer, and includes: receiving a raw signal from the accelerometer during at least one step being taken by the user on the ground; identifying, in the received raw signal, at least one characteristic signature; associating the at least one characteristic signature to physical properties of the ground; and generating a signal indicating the physical properties based on said association. The generated signal can further be used to advise a user of a risk of falling based on at least the physical properties of the ground.

摘要： The system (10) and the method are used for forecasting the electrical conductivity of an anode (12) for aluminum production before the anode (12) is baked. In the system (10), at least one receiving coil (20,22) is coupled to an electromagnetic field emitting unit (14,18). A sensing device (30) is connected to the receiving coil (20,22), the sensing device (30) outputting a signal indicative of a variation of the electromagnetic field received by the receiving coil (20,22) as the crude anode (12), or a portion thereof, passes inside the receiving coil (20,22). A value indicative of the electrical conductivity of the anode (12) is then calculated using the signal from the sensing device (30) and signals previously obtained using reference anodes (12). This way, the electrical conductivity of the anodes (12) can be forecasted before the crude anodes (12) are baked.
摘要翻译：系统（10）和方法用于在阳极（12）烘烤之前预测用于铝生产的阳极（12）的导电性。在系统（10）中，至少一个接收线圈（20,22）耦合到电磁场发射单元（14,18）。感测装置（30）连接到接收线圈（20,22），感测装置（30）输出指示由接收线圈（20,22）接收的电磁场的变化的信号作为粗阳极（ 12）或其一部分通过接收线圈（20,22）内。然后使用来自感测装置（30）的信号和先前使用参考阳极（12）获得的信号来计算指示阳极（12）的电导率的值。这样，可以在粗阳极（12）被烘烤之前预测阳极（12）的电导率。

摘要： The method can include the steps of: providing a given current across each one of a plurality of current paths linking two opposite faces of the anode, the current paths being dispersed along a median plane located between the two opposite faces; measuring a voltage value independently across each one of a plurality of voltage paths linking the two opposite faces of the anode, each one of the plurality of voltage paths being positioned adjacent to a corresponding one of the current paths and forming a corresponding pair therewith, the path pairs thus being dispersed along the median plane; and processing an independent resistivity value for each one of the path pairs based at least on its given current and its measured voltage value.
