Patent number: 10036712Abstract: A defect inspection system is provided for inspection of defects in the surface of a sample. An array of light sources is used, with different light sources providing light to the sample from different directions. A main direction of illumination is defined with highest intensity, and this direction evolves over time. By providing varying directional illumination instead of blanket illumination, it becomes easier to detect defects.Type: GrantFiled: October 13, 2014Date of Patent: July 31, 2018Assignee: PHILIPS LIGHTING HOLDING B.V.Inventors: Shuguang Kuai, Mark Christoph Jaeger, Weixi Zhou

Patent number: 10016574Abstract: The invention relates to a system (102) for providing biofeedback to a person (104). The system (102) comprises a source (106) for generating a source signal (108) and a transducer (110) for generating a measurement signal (112) in response to a physiological parameter (114) indicative for mental relaxation of the person (104). The system (102) furthermore comprises a filter (116) for variably filtering the source signal via modifying a cut-off frequency in response to the measurement signal (112) and an interface (118) for providing a biofeedback signal (119) to the person on the basis of the source signal as variably filtered by the filter (116).Type: GrantFiled: December 14, 2011Date of Patent: July 10, 2018Assignee: Koninklijke Philips N.V.Inventors: Mark Christoph Jaeger, Adrianus Johannes Maria Denissen, Murray Fulton Gillies

Patent number: 9929875Abstract: A space control system and a detection system are disclosed. The detection system is configured for distinguishing a moving living object, e.g. a human being, from a moving machine object in a space. The system comprises an imaging apparatus configured for producing a plurality of images over time of at least a part of the space. The images have a good spatial resolution. The system also comprises a processor configured for determining motion signals of the moving living object and the moving machine object from the plurality of images. The processor is configured to transform the motion signals to a frequency domain and distinguish in the frequency domain between motion signals related to moving living objects and motion signals related to the moving machine objects. Accordingly, the system is enabled to detect at least one of the living object and the machine object in the part of the space on the basis of the distinguished motion signals.Type: GrantFiled: September 11, 2014Date of Patent: March 27, 2018Assignee: PHILIPS LIGHTING HOLDING B.V.Inventors: Shuguang Kuai, Guofu Zhuo, Mark Christoph Jaeger
