  • Patent number: 10281986
    Abstract: Methods of providing user accessibility to an electronic device are provided. Methods include receiving a physical input via at least one user input device in a user interface, generating, in the user interface, a sensor output signal responsive to receiving the physical input from the user, and interpreting the sensor output signal as a gesture input signal that that is received by the electronic device. The gesture input signal is operative to cause the electronic device to perform a function corresponding to a gesture that is physically applied to the electronic device.

  • Patent number: 8610900
    Abstract: The present invention relates to an apparatus for low coherence optical imaging, and more particularly to an apparatus for low coherence optical imaging which can obtain the information of the different depths of a sample simultaneously. The apparatus comprises a phase transformation unit or a beam shift unit. The phase transformation unit or beam shift unit transforms and reflects the reference light, such that the reflected reference light comprises different phases at the different positions of a cross-section. When the reference light and a information light from the sample are superimposed on a photo detector, the information of the different depths of the sample is obtained. By using the apparatus of the present invention, the elements, the volume, and the cost of the apparatus are reduced. Because of only two-dimensional scanning is required, the scanning rate is improved.
