20080261744 | GEAR UNIT AND USE OF THE SAME - The gear unit for use with a manually adjustable electric component has a manually operable adjusting shaft and a reduction gear including a rotatable ball cage and a plurality of balls as well as a race ring element having a spring and retaining portion that encircles the race ring externally. Such a gear unit allows greatly reduced dimensions and furthermore offers a considerable dielectric strength. | 10-23-2008 |
20100013464 | INDUCTIVE PROXIMITY SENSOR FOR EMBEDDED MOUNTING AND METHOD OF DESIGN - The invention relates to an inductive proximity sensor for embedding in a mild steel mounting plate, comprising an enclosure with a front wall of synthetic material forming a sensing face at a front end of the enclosure, an oscillator comprising a sensor coil with a core made of a material with a relative magnetic permeability larger than 1, typically a ferrite, which is arranged within the enclosure behind the front wall so that an open side of the core is directed towards the sensing face in order to direct the magnetic field of the coil towards a target in front of the sensing face, a hollow cylindrical metal member arranged perpendicular to the sensing face and surrounding the core, and a measuring circuit for measuring an attenuation of the oscillator due to eddy currents. The core is radially surrounded by a metal layer with a low electrical resistivity of less than 15 μΩ·cm and with a thickness of less than 40 μm, in order to improve the embeddability of the sensor. Alternatively, this thin metal layer may be omitted, if the electrical resistivity of the metal member is adjusted to a value in the range of 15 μΩ·cm-50 μΩ·cm. | 01-21-2010 |
20100061723 | OPTICAL SENSOR SYSTEM, OPTICAL SENSOR DEVICE AND BUS SEGMENT FOR CONNECTING THE DEVICE TO A BUS OF THE SYSTEM - An optical sensor system comprises one or more optical sensor devices, a master device and an electrical bus connecting the sensor devices to the master device. The bus comprises a signal daisy chain for the transmission of synchronization events. The sensor devices are adapted to detect a synchronization event at a signal input terminal, to time an optical activity based on this synchronization event and to provide at a signal output terminal a synchronization event delayed by an offset time with respect to the detected synchronization event. A property of the synchronization events provided by the sensor devices is indicative of an output value of the respective sensor device, corresponding to a state of an optical section to which the sensor is sensitive. Diodes are connected between the signal output terminals of the sensor devices and a signal line of the bus, which is connected to a signal input terminal of the master device, so that the latter receives the synchronization events from the sensor devices. The master device comprises means for extracting the output values of the sensor devices from these synchronization events. A sensor device for such a system comprises an enclosure of cuboid outer shape adapted to be mounted to a mounting rail so that the longitudinal direction of the rail is perpendicular to lateral sides of the enclosure. An electrical connector with the signal input and output terminals and with power supply terminals is arranged at a side connecting the lateral sides of the enclosure. Bus segments are provided for connecting the sensor devices to the system bus. | 03-11-2010 |

20120256096 | METHOD AND DEVICE FOR MONITORING MOVING OBJECTS - A method and a device for monitoring objects moving along a trajectory. The objects include a section that is transparent or translucent. The objects subsequently cross a light beam at the section. The presence or absence of an object is determined during a transitional time period during which substantially no light or light within a wavelength range substantially untransmittable through the section is detected. A monitoring device generates an output signal based on the light detection indicating the presence or absence of an object. | 10-11-2012 |
