摘要： An apparatus for imaging a fingerprint operates in a selected mode to provide a finger recognition and/or a finger navigation application. At least one light source illuminates at least one partition of a finger interface upon which a user places a finger (or thumb). Light reflected from the finger is captured by at least one image sensing region aligned to receive reflected light emitted from the illuminating light source(s). The illuminating light sources are selected depending on the selected mode of operation to illuminate only those partitions of the finger interface necessary for operation of the selected mode.

摘要： An imaging system for imaging a fingerprint operates in at least two different modes to provide both finger recognition and finger navigation applications. A light source illuminates a swipe interface having an elongated sensing area upon which a user swipes a finger. Light reflected from the finger is captured by an optical image sensor as image data representing a sequence of images resulting from motion of the digit over the sensing area of the swipe interface. The captured image data is output by the optical image sensor for processing of the data in one of the at least two different modes.

摘要： An apparatus for imaging a fingerprint operates in a selected mode to provide a finger recognition and/or a finger navigation application. Multiple light sources are capable of being sequentially selected for illumination of corresponding partitions of a finger interface upon which a user places a finger (or thumb). The selection of light sources is based on the selected mode of operation. A single sensor captures light reflected from the digit in all illuminated partitions as sequential partition images. The sensor further outputs image data corresponding to the captured partition images for processing in the selected mode.

摘要： An imaging system captures a sequence of images representing finger lift-up and finger put-down motions over a sensing area and produces an image signal for use in detecting a click event. At least one light source illuminates a finger interface upon which a user places a finger (or thumb). Light reflected from the finger is captured by an image sensor as image data corresponding to the sequence of images. At least one image signal is produced in connection with or based on the image data. The image signal is used to detect a finger lift-up or finger put-down motion. A click, such as a single click, double click or triple click, is detected based on a combination of finger lift-up and finger put-down motions within a configurable time range.

摘要： Methods for determining actuation of a capacitive button are described. In some embodiments, indicia from the at least three distinct sensor electrodes associated with at least three sensor electrode elements comprising the capacitive button are received, the indicia indicative of interaction of an input object with the at least three distinct sensor electrodes. The actuation of the capacitive button is then determined, based at least in part on satisfying a set of criteria comprising: a location condition concerning a location of the input object relative to a center of the capacitive button, and a coupling condition concerning a change in capacitive coupling of the at least three distinct sensor electrodes associated with the at least three sensor electrode elements comprising the capacitive button.

摘要： An a data input system includes an encoded pad having position encoding and a data input device adapted to image a portion of the encoded pad to determine position and orientation of the data input device relative to the encoded pad. The encoding pad includes a plurality of correlation windows. Each correlation window includes a primary encoding marker in form of vertical line segment and a set of secondary encoding markers in form of diagonal line segments, at least one diagonal line segment intersecting the vertical line segment at an intersection angle. Spacing of the diagonal line segments encodes the X-axis position of the input device relative to the encoding pad. Intersection angle encodes the Y-axis position of the input device relative to the encoding pad. Angle of the primary encoding marker vertical line segment within the frame of the captured image encodes the angular orientation of the input device relative to the axes of the encoded pad.

摘要： A microwave imaging system uses microwave radiation provided by a microwave source to image targets. The system includes an array of antenna elements that are capable of being programmed with a respective transmission coefficient to direct the microwave illumination from the microwave source toward a position on the target. The antenna elements are further capable of being programmed with a respective additional transmission coefficient to receive reflected microwave illumination reflected from the position on the target and direct the reflected microwave illumination towards a microwave receiver. A processor is operable to measure an intensity of the reflected microwave illumination to determine a value of a pixel within an image of the target. Multiple beams can be directed towards the target to obtain corresponding pixel values for use by the processor in constructing the image.

Each of the antenna elements in a first array is capable of being programmed with a respective phase delay to direct a transmit beam of microwave illumination toward the target in a transmit beam pattern, and each of the antenna elements in a second array is capable of receiving reflected microwave illumination reflected from the target in a receive beam in a receive beam pattern complementary to the transmit beam pattern. The microwave image of the target is formed at an intersection between the transmit beam and the receive beam.

摘要： A microwave imaging system suppresses sidelobes in a microwave image captured using a sparse antenna array using an illumination system that operates in two different illumination modes. The antenna array including subarrays of antenna elements arranged in a sparse geometry to form complementary subarray patterns. The illumination system operates in a first mode to transmit microwave illumination to both of the complementary subarray patterns of the antenna array and receive reflected microwave illumination from both of the complementary subarray patterns of the antenna array to produce a first receive signal. The illumination system further operates in a second mode to transmit microwave illumination to a first one of the complementary subarray patterns of the antenna array and receive reflected microwave illumination from a second one of the complementary subarray patterns of the antenna array to produce a second receive signal. Sidelobes are suppressed using a linear combination of the first and second receive signals.

摘要： A microwave imaging system uses microwave radiation provided by a microwave source to image targets. The system includes an array of antenna elements that are capable of being programmed with a respective direction coefficient to direct the microwave illumination from the microwave source toward a position on the target. The antenna elements are further capable of being programmed to receive reflected microwave illumination reflected from the position on the target. A processor is operable to measure an intensity of the reflected microwave illumination to determine a value of a pixel within an image of the target.
