A capacitive tile tactile sensor is described and includes several groups of individual sensors each controlled by a dedicated IC. Individual sensors are formed by sensing electrodes on one side of the sensor and a single ground electrode on the other side, the ground electrode is separated from the sensing electrodes by a compressible dielectric layer. A single electrical connection between the ground electrode and the sensing electrode layer allows for routing of all electrical connections including individual electrodes and a ground electrode to appropriate ICs within the same layer using conductive ink or other similar techniques. Stand-alone configurations are described as well as those adapted for communicating with outside control means including a personal computer. Arranging groups of sensors in parallel with each other creates a matrix of sensors while arranging them along a single line creates a linear strip sensor. Using off-the-shelf capacitance-sensing ICs to control a limited number of capacitance sensors allows reducing the number of electrical connections to the sensor array and increasing its reliability.

In a machine tool which includes a rotary shaft configured to allow a tool or a workpiece to be attached thereto, a driving unit for causing the rotary shaft to rotate is regulated to change a rotation speed of the rotary shaft in such a manner that the rotation speed oscillates with a given amplitude and a given period with respect to a given mean rotation speed, so that chatter vibrations can be suppressed. A parameter display control unit configured to cause a display device to display parameter information related to predetermined parameters for changing at least one of the mean rotation speed, the amplitude and the period is provided so that the parameters can be changed based upon the parameter information displayed in the display device.

A device for protecting medical apparatus from contamination by infectious agents comprises a containment body having an inlet destined to be set in fluid communication with an extracorporeal circuit of blood, and an outlet destined to be connected to a fluid line operatively connected to a pressure gauge of a medical apparatus. The inlet is in gas communication with the outlet across an internal cavity of the containment body. Two hydrophobic membranes are predisposed in the containment body between the inlet and the outlet. The membranes each define an anticontamination barrier which is gas-permeable. The device transmits the pressure of the extracorporeal circuit to the pressure gauge, with no relevant loss of head, while at the same time protecting, with a high degree of security, the medical apparatus from risks of contamination by pathogens originating in the extracorporeal circuit.

A horizontal-axis wind turbine of a rotor-support design is provided in which the structural load of the wind turbine rotor is carried by the wind turbine tower itself. The turbine uses a composite shaft to transfer torque from the wind turbine rotor to the generator, the shaft having high torsional strength but being flexible in bending. This prevents the transmission of bending moments from the rotor hub to the generator system. Accordingly, the components of the turbine can be rigidly mounted to the turbine main frame, removing the need for vibration damping elements. The result is a wind turbine of reduced weight, which can be modeled and designed for improved efficiency and performance. Furthermore, as the turbine components do not have to be load-balanced, the turbine can be of a modular construction for relatively easy servicing and / or upgrading.

An abnormality of a generator provided with a plurality of power supply units is easily detected. Each of the power supply units includes each of output windings L1 to L4, which are wound independently of each other around the single iron core, and each of rectifier circuits 2 to 5. The power supply units produce an integrated output power. Control means 33 to 35 control the rectifier circuits such that an output voltage agrees with a target voltage Vref. In a case where an added up power W becomes a power target value Wref, when the added up current I further increases, a power comparing section 39 reduces the target voltage Vref to prevent the rectifier circuits from outputting power. Further, when the added up current I exceeds a current upper limit ILMT, a gate pulse is stopped.
