  • Patent number: 10186187
    Abstract: A display may have an array of pixels arranged in rows and columns. Display driver circuitry may load data into the pixels via data lines that extend along the columns. The display driver circuitry may include gate driver circuitry that supplies horizontal control signals to rows of the pixels. The horizontal control signals may include emission enable signals for controlling emission enable transistors and scan signals for controlling switching transistors. During an emission phase of operation for the display, the emission enable signal may be pulse-width modulated by the emission control gate driver circuits in the gate driver circuitry to control the output of the light-emitting diodes. The emission control gate driver circuits may be controlled using an emission start signal and a pair of two-phase clocks.

  • Patent number: 10162416
    Abstract: A system is provided that dynamically converts an input signal into a haptic signal. The system generates effect objects, where an effect object includes an instruction to perform a haptic conversion algorithm on the input signal to convert the input signal into an output signal, and where an order of the effect objects is defined. The system further receives the input signal. The system further applies the effect objects to the input signal in the defined order, where the output signal of an effect object forms the haptic signal. The system further sends the haptic signal to a haptic output device, where the haptic signal causes the haptic output device to output haptic effects.

  • Patent number: 10133355
    Abstract: Projected input and output devices adapt to a desktop environment by sensing objects at the desktop environment and altering projected light in response to the sensed objects. For instance, projection of input and output devices is altered to limit illumination against and end user's hands or other objects disposed at a projection surface. End user hand positions and motions are detected to provide gesture support for adapting a projection work space, and configurations of projected devices are stored so that an end user can rapidly recreate a projected desktop. A projector scan adjusts to limit traces across inactive portions of the display surface and to increase traces at predetermined areas, such as video windows.

  • Patent number: 10108276
    Abstract: A mouse device includes a mouse casing, a first sensing module, a second sensing module and a switching module. The mouse casing includes a casing opening. Both of the first sensing module and the second sensing module are disposed on the switching module. Moreover, a part of the first sensing module and a part of the second sensing module are selectively exposed outside the casing opening. When the first sensing module or the second sensing module exposed outside the casing opening is rotated by the user, a switching body of the switching module is correspondingly rotated relative to the mouse casing. Consequently, a moving resolution of the mouse device is adjustable according to the practical requirements. The switching module has a simple mechanism for changing the moving resolution of the mouse device in a simple manner.

  • Patent number: 10078384
    Abstract: A haptic effect enabled device for producing a haptic effect. In some cases, the haptic effect may represent a component of a spatial pattern represented on a surface of the haptic effect enabled device. In some cases, the haptic effect enabled device may comprise a haptic output device, a drive module, and a drive circuit. The drive module may receive information indicative of a location of a touch input at the surface and determine whether the touch input's location corresponds with a location of one of multiple components of the spatial pattern. The drive module may generate a drive signal that the drive circuit then applies to the haptic output device to generate the haptic effect.

  • Patent number: 10067535
    Abstract: An electronic device may be provided with a display mounted in a housing. The display may have an array of display pixels that provide image light to a user. The array of display pixels may form an active display structure with a rectangular shape. The rectangular active display structure may be surrounded by an inactive border region. Optical structures such as upper structures formed from a sheet of glass and lower optical structures that lie beneath the sheet of glass may be configured to bend light from the display pixels along the periphery of the active display structure. The upper optical structures may have an area that is larger than the area of the active display structure, so that the presence of the optical structures may serve to enlarge the apparent size of the display. The lower and upper optical structures may have curved surfaces for bending the light.

  • Patent number: 10061387
    Abstract: An apparatus, method, and computer program product are provided for generating a projected user interface. The apparatus may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured, with the processor, to cause the apparatus to receive information regarding a detected position of the user's body and to determine whether the detected position is an activation position, in which case the projection of a user interface may be provided. The user interface may be projected on an area on the user's body, such as a hand or a forearm, or on the surface of an object. The activation position may thus be a predefined position of the user's body in which effective projection of the user interface onto the surface and user interaction with the user interface is facilitated.
