    Abstract: A sensor system for detecting motion in a predefined direction of motion (30) of an infrared light source (29) has at least one pair of infrared light sensors (4, 5; 36, 37), which are arranged side by side with respect to the direction of motion (30) and, thus, define a sensor coverage zone (17) determined by the distance between distal ends (16) (with respect to the direction of motion) of the infrared light sensors. During exposure to the infrared light source, the sensors provide electrical signals, the charge signs of which are opposite each other, for detecting the motion of the infrared light source (29). The sensor system (1) has a window (7) positioned between the infrared light source (29) and the sensors such that the infrared light of the infrared light source (29) radiates onto the sensors. The sensors are arranged behind the window and are adjusted relative to the width (41) of the window to extend in the direction of motion such that, beyond a predetermined limit distance (20) away from the window, each of the sensors has a full illumination zone (22, 23), which defines the locations from which the infrared light source (29) fully illuminates only one of the sensors (4, 36 or 5, 37). The full illumination zones (22, 23) do not spatially overlap beyond the limit distance (20); and the window width (41) is smaller than the sensor coverage zone (17) in the direction of motion (30).

    Abstract: An optical navigation device, such as an optical navigation joystick or mouse, includes an internal redirector which may be separate or formed from material of a touch surface of the optical device. The redirector is disposed at an angle with respect to a plane of the touch surface, operative to reflect light which would otherwise strike the touch surface at a low angle and be internally reflected. The light may be reflected in a direction away from a light sensor of the device, reducing sensed internally reflected light, or may be reflected into the touch surface at a higher angle, potentially increasing a quantity of good signal. The redirector may also include portions which block light directly emitted from a light emitter, or reflected off other surfaces of the navigation device.

    Abstract: The invention provides a glare reduction apparatus disposed in an object illuminated by a light source. The glare reduction device includes an electro-optical device covering a surface of the object. A light sensing device is disposed on a first fixed point of the object. A controller is electrically coupled to the electro-optical device and the light sensing device, wherein the controller calculates a corresponding light sensing position of the electro-optical device according to a light sensing position of the light sensing device which directly receives light from the light source, to reduce the light transmittivity of the corresponding light sensing position of the electro-optical device to generate a light shielding region. The light shielding region attenuates the light from the light source to a second fixed point of the object.

    Abstract: Apparatuses and methods for limiting the angle of incidence (AOI) of light reaching a dichroic filter. The apparatus may include an AOI filter element and the dichroic filter. The apparatus may be a sensor and may include a photodetector. The dichroic filter may be configured to prevent light having a wavelength outside a band pass region from reaching the photodetector and to pass light having a wavelength within the band pass. Physical limitations of the dichroic filter may preclude the dichroic filter from preventing high AOI light having a wavelength outside a band pass region from reaching the photodetector. The AOI filter element may be configured to prevent light having a high AOI from reaching the dichroic band pass filter and to propagate light having a low AOI to the dichroic band pass filter. The AOI filter element may be a fiber optic bundle comprising a plurality of optical fibers.
