摘要:
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.

Embodiments of a finger navigation device are described. In one embodiment, the finger navigation device includes a light guide film (LGF), a light source, a sensor, and a navigation engine. At least a portion of the LGF exhibits total internal reflection (TIR) and the light source is in optical communication with the LGF and configured to inject light into the LGF. The sensor is configured to detect light that exits from the LGF after being reflected from a finger that is proximate the LGF and the navigation engine is configured to generate lateral movement information, which is indicative of lateral movement of the finger relative to the sensor, in response to light that is reflected from the finger and detected by the sensor. Other embodiments of the finger navigation device are also described.

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.

Various embodiments provide an enhanced mobile computing experience by providing an input device in a mobile electronic device that is configured to accurately and quickly re-center a button or other user interface while providing a sensation of enhanced tactile feedback to a user. The biasing force of a magnetic re-centering mechanism is employed to overcome frictional forces acting on the button during its travel forwards and backwards and tilting to insure that the button is returned quickly and accurately to a resting position. The magnetic re-centering mechanism has a low profile, and permits the input device and the mobile electronic device within which the input device is disposed to have small form factors.

An optical input device for finger input on an electronic computing device. The optical input device includes a thin-film transistor (TFT) imager and an integrated circuit (IC). The TFT imager includes a protective layer, a substrate, and a TFT array. The protective layer has a finger contact surface. The TFT array includes photo-sensitive thin-film transistors disposed on a surface of the substrate, between the substrate and the protective layer. The TFT array generates image signals corresponding to physical features of a user's finger in contact with the finger contact surface of the protective layer. The integrated circuit is coupled to the TFT imager. The integrated circuit processes the image signals from the TFT array.

An input device of an electronic device includes a position sensor, a base, a slider, and a controller. The position sensor includes a first positioning element and a second positioning element with the first positioning element being operably coupled relative to the second positioning element. A slider includes the first positioning element. The base is configured to guide slidable movement of the slider along a single axis relative to the base and the base includes the second positioning element. The controller is configured to capture a user input based on a linear slidable position of the slider relative to the base with the linear position being determined from a position of the first positioning element relative to the second positioning element.
