Abstract: A receiver circuit capable of characterizing a communication channel or link is disclosed. The receiver circuit may receive an input signal that encodes multiple data symbols, and may sample the input signal to generate recovered symbols, a recovered clock signal, and samples. Using the samples and recovered symbols, the receiver circuit may generate recovered data. The receiver circuit may, in response to a detection of a particular logic value in the recovered data, count a number of occurrences of a particular logic value in the samples over a range of sample threshold values and sample times to generate a conditional probability distribution of the input signal. Using a statistical measurement of the conditional probability distribution, the receiver circuit may adjust one of its operating parameters.

Abstract: The present application provides a biomimetic finger including an epidermis provided with a first liquid outlet hole; an elastomer wrapped and mounted within the epidermis, the elastomer is provided with a second liquid outlet hole, and the second liquid outlet hole is communicated with the first liquid outlet hole; a rigid support member, wrapped and mounted within the epidermis; and a liquid delivery tube, a first end of the liquid delivery tube is wrapped and mounted within the epidermis, the first end of the liquid delivery tube is supported between the rigid support member and the elastomer, a side of the first end of the liquid delivery tube is provided with a third liquid outlet hole, the third liquid outlet hole is communicated with the second liquid outlet hole, and a second end of the liquid delivery tube extends to an outside of the epidermis.

Abstract: Systems and methods described herein relate to a near-eye display using a pinhole aperture array. In some examples, a near-eye display system includes a ray-limiting structure to provide a pinhole aperture array with a plurality of apertures. The plurality of apertures can each have a shape defined by radially extending elements. Examples also describe extended reality (XR) devices including such a near-eye display system and methods utilizing the near-eye display system.

Abstract: A device, system and method for enhancing high-contrast and text regions in projected images is provided. A device applies, to an input image: a high-contrast sharpening filter sharpening high-contrast regions producing a high-contrast sharpened image; and a background sharpening filter sharpening other regions of the input producing a background sharpened image, the background sharpening filter applying less sharpening than the high-contrast sharpening filter.
