  • Patent number: 10228799
    Abstract: Pressure-sensing touch systems and methods are disclosed for sensing the occurrence of a touch event based on pressure applied at a touch location. The touch system includes a light-source system and a detector system operably adjacent respective input and output edges of a waveguide. Pressure at a touch location on the waveguide gives rise to a touch event causes the waveguide to bend or flex. The waveguide bending causes a change in the optical paths of light traveling by FTIR, causing the light distribution in the output light to change. The changes are detected and are used to determine whether a touch event occurred, as well as the time-evolution of the touch event. The changes in the output light can include polarization changes caused by birefringence induced in the waveguide by the applied pressure applied. Various detector configurations are disclosed for sensing the location and pressure of a touch event.

  • Patent number: 9893102
    Abstract: A sensor is provided for capturing images of skin topology having an upper surface providing a platen, and a one or two-dimensional array of light sensing pixel elements for receiving light representative of the topology of skin when upon the upper surface and illuminated by at least redirected ambient light received within the sensor through the upper surface. One or more layers or coatings of reflective or scattering materials are provided in the sensor for redirecting ambient light by one or more of reflection, scattering, or propagation towards the platen to illuminate the skin. The pixel elements are sensitive to one or more selected wavelengths or wavelength ranges of the ambient light present. Optional light source(s) may be provided for use when ambient light present is inadequate for proper sensor operation.

  • Patent number: 9886408
    Abstract: A protection circuit can be used with a computer system having a master device and at least one slave device that are connected by an inter-integrated circuit (I2C) bus. A first access request is received that includes an address that identifies a first slave device. In response to a permissible mode, the first access request is communicated to the first slave device using the I2C bus. A sticky protection bit can be set. In response to the sticky protection bit being set, the protection circuit can be placed in a protected mode. A second access request is received. The second access request can be determined to be a protected access to the first slave device. In response to the determining and the protected mode, the second access request to the first slave device can be denied.

  • Patent number: 9830496
    Abstract: Disclosed is a fingerprint input device using a portable terminal equipped with a camera, and an external optical device for inputting a fingerprint. According to the present invention, a fingerprint image may be generated by an optical fingerprint input method by using the external optical device of the present invention even when an existing portable terminal does not have a configuration for an optical fingerprint input. To this end, the external optical device is provided as an external type to be mounted in the existing portable terminal provided with a camera, and has an optical refractor and a mirror. The external optical device may generate a user's fingerprint image by an optical fingerprint input method, in accordance with circumstances, without interrupting the main use of a camera and an LED of the existing portable terminal.

  • Patent number: 9829614
    Abstract: Systems and methods for optical imaging are disclosed. The optical fingerprint sensor includes an image sensor array; a collimator filter layer disposed above the image sensor array, the collimator filter layer having an array of apertures; and an illumination layer disposed above the collimator filter layer. The collimator filter layer filters reflected light such that only certain of the reflected light beams reach optical sensing elements in the image sensor array. Employing the collimator filter layer prevents blurring while allowing for a lower-profile image sensor.
