  • Publication number: 20210303152
    Abstract: In some examples, an input device includes a non-linear component, such as a diode. In response to a drive signal, such as a sinusoidal wave, the non-linear passive input device can produce a non-linear output that includes frequency content at the second and other higher harmonics of the fundamental frequency of the drive signal, for example. In some examples, drive electrodes can be driven with a drive signal having one of two fundamental frequencies such that the frequency of the drive signals are applied in an alternating pattern. The electronic device can sense the signal of the stylus to determine the coarse location of the stylus along the sense electrodes and, based on the frequency content of the received signal, a fine location along the axis of the drive electrodes.

  • Patent number: 9930317
    Abstract: A method for applying power in a plurality of pulses to the projection source to control the projection source to emit coherent light during an exposure interval comprising at least two sub-intervals, the applied power causing the projection source to have different temperatures during first and second sub-intervals of the at least two sub-intervals; and emitting light from the projection source, wherein the projection source emits light having different wavelengths during the first and second sub-intervals in accordance with the different temperatures of the projection source.

  • Patent number: 9826216
    Abstract: A pattern projection system includes a coherent light source, a repositionable DOE disposed to receive coherent light from said coherent light source and disposed to output at least one pattern of projectable light onto a scene to be imaged by an (x,y) two-dimensional optical acquisition system. Coherent light speckle artifacts in the projected pattern are reduced by rapidly controllably repositioning the DOE or the entire pattern projection system. Different projectable patterns are selected from a set of M patterns that are related to each other by a translation and/or rotation operation in two-dimensional cosine space. A resultant (x,y,z) depth map has improved quality and robustness due to projection of the selected patterns. Three-dimensional (x,y,z) depth data obtained from two-dimensional imaged data including despeckling is higher quality data than if projected patterns without despeckling were used.

  • Patent number: 9521399
    Abstract: Dynamic projection of at least first and second patterns contributes detectable disparity onto a scene that includes a target object. The scene is imaged with two-dimensional cameras whose acquired imagery includes disparity contributions whose presence enable a three-dimensional reconstruction depth map to be rapidly and accurately generated. In one embodiment coherent light is input to a first DOE within whose near range output is disposed a second DOE, whose far range output projects an image. Electronically varying effective optical distance between the two DOEs varies the pattern projected from the second DOE. A processor system and algorithms enable dynamic intelligent selection of projected patterns to more readily discern target object characteristics: shape, size, velocity. Patterns can implement spatio-temporal depth reconstruction, spatio-temporal depth reconstruction, and even single-camera spatio-temporal light coding reconstruction.
