Abstract: A motorization device comprises two substantially parallel winding cylinders, at least one longitudinal link element to maintain a predetermined distance between the cylinders, and wound around said winding tracks, the link element consequently having a crossover point between the winding cylinders, two flexible tracks fixed to the winding cylinders and arranged facing and in contact with one another at the point of contact, a winding cylinder and flexible track assembly forming a fitting, a prestressing force being applied at the point of contact under the effect of the link element. The flexible tracks have a spiral form configured that the point of contact between the two flexible tracks in spiral form, situated between said winding cylinders, is offset relative to the crossover point, such that a torque dependent on the distance between the point of contact and the crossover point is applied, to provoke the mutual rotation of the fittings.

Abstract: Apparatus and methods of trimming resistors are disclosed. In one embodiment, a method of controlling the PCR of a thin film resistor is provided. The method includes applying a first current to a resistor so as to alter a property of the resistor, and measuring the property of the resistor. Applying the first current and measuring the property of the resistor can be repeated until the PCR of the resistor is within an acceptable tolerance of a desired value for the property of the resistor.

Abstract: Integrated voltage divider comprising partial resistors (R1 ,R2) formed of paths of polycrystalline semiconductor material applied over a dielectric layer (4) on a semiconductor substrate (5). Under the paths, each forming a partial resistor (R1,R2) in the semiconductor substrate (5), a well (6 and 7 respectively) is formed having a conductivity type opposite to the conductivity type of the semiconductor substrate (5). The total surfaces of the paths forming the partial resistors (R1,R2) are dimensioned so that their ratio equals the inverse ratio of the resistor values of the two partial resistors (R1 ,R2).

Abstract: A robot joint comprising first and second link members having respective congruent arcuate surfaces joined by complementary flexible metal bands and having an integral potentiometer transducer mechanism.
