| 20110286009 | OPTICAL SENSOR - An optical sensor apparatus to detect objects within a monitored region includes a housing having a window. A sensor includes a transmitting/receiving unit arranged inside the housing and rotatable around an axis. The transmitting/receiving unit includes a transmitter to emit light rays and a receiver to receive light rays. The transmitted light rays and the received light rays are conducted through the window in the housing. The window is optically adapted to shape the transmitted light rays and the received light rays into beams. | 11-24-2011 |
| 20110248086 | OPTOELECTRONIC DEVICE - An optoelectronic device for detecting marks with defined contrast patterns includes a transmitter to emit polarized light beams, a receiver to receive light beams and having an output to produce receiving signals representing the received light beams, and a an evaluation unit to which the receiving signals are fed and in which the contrast pattern of a mark is detected with the aid of the receiving signals present at the receiver output. A thin-film polarization filter is arranged in front of the receiver to filter out a share of the received light beams specular reflected back by the mark. | 10-13-2011 |
| 20100085580 | Optical Sensor - The invention relates to an optical sensor for the detection of objects in a detection range, comprising a transmitter emitting transmitting light beams, a receiver that receives receiving light beams, and an evaluation unit, in which an object determination signal is generated by the evaluation of the receiving signals of the receiver. An optical element, having at least one boundary surface in the form of a free-form surface, is associated with the transmitter and/or the receiver for forming the beams of the transmitting light beams and/or the receiving light beams. | 04-08-2010 |
| 20090121886 | SENSOR - A sensor comprises a sensing element to generate output signals corresponding to receiving signals received from an object and an evaluation unit coupled to the sensing element and weighting the output signals from the sensing element with at least one switching threshold to generate object detection signals. The evaluation unit includes a key adapted to selectively reset the at least one switching threshold to higher and lower values through differences in activation of the key. | 05-14-2009 |
| 20090101791 | Optical Sensor - The invention relates to an optical sensor ( | 04-23-2009 |
| 20090084186 | SENSOR ARRANGEMENT - A sensor arrangement for detecting objects, includes an ultrasonic sensor and an optical sensor integrated into the ultrasonic sensor. | 04-02-2009 |
