Abstract: An optical touch screen that utilizes a planar transparent sheet and that is configured to determine the position of a touch event on the transparent sheet is disclosed. Light-source elements and light-sensing elements are operably disposed at a perimeter of the transparent sheet. Light is detected over lines-of-sight between the light-source elements and the light-sensing elements. Attenuated lines-of-sight due to the touch event are determined. Central lines are established based on the attenuated lines-of-sight. The locations of central-line intersections are then established. The average of the locations of the central-line intersections is then used to establish the location of the touch event.

Abstract: Embodiments of the disclosure relate to increasing radixes of digital data switches and communications switches, and related components and methods. In one embodiment, a gearbox transfers a plurality of high bandwidth signals between a communications switch and a plurality of devices. The gearbox is configured to combine one or more groups of uplink component signals into one or more respective uplink combined signals, and transmit each combined signal to the communications switch. Each uplink component signal is combined into only one of the at least one respective downlink combined signal to ensure that no individual uplink component signal is divided between multiple uplink combined signals, thereby simplifying the process of combining the uplink component signals and dividing the uplink combined signals. The communications switch is then configured to divide each uplink combined signal back into its respective uplink component signals.

Abstract: Solar-redshift systems comprise an integral array of redshift modules, each having at least a focusing device, a target, and a quantum-dot vessel. The quantum-dot vessel contains quantum dots that emit light having an emission wavelength. The focusing device directs incident solar radiation through a focusing gap and toward the quantum-dot vessel, or into a slab waveguide and then toward the quantum-dot vessel, causing the quantum dots to emit redshifted light having the emission wavelength. The redshifted light is directed to the target, examples of which include a photovoltaic material or a living photosynthetic organism. The target has increased sensitivity or response to photons having the wavelength of the redshifted light. A trapping reflector component of the quantum-dot vessel prevents loss of redshifted light to the environment outside the solar-redshift system and allows undesirable infrared light to be removed from the system.

Abstract: A fingerprint sensing module for a touch screen device. The fingerprint sensing module includes a sensor, a light source, a motion detector, and an image processor. The sensor sets to capture portions for a fingerprint image as a finger is slid over the sensor. The motion detector determines a rate of the finger movement as the finger is slide over the touch screen device. The image processor reads fingerprint images from the sensor and the fingerprint motion data from the motion detector. The image processor subsequently combines portions of the fingerprint images into a complete fingerprint in accordance with the rate of the finger's movement.
